Abstract
Child malnutrition (CM) is a global public health problem. It contributes to poor health in one in four children under five years worldwide and causes serious health problems in children, including stunted, wasted, and overweight growth. These serious public health issues lead to a higher chance of living in poverty in adulthood. Malnutrition is related with reduced economic productivity and increases the serious national and international burden. Currently, there is no meaningful therapeutic intervention of CM, and the use of different therapeutic foods has shown poor outcomes among supplemented malnourished children. The role of metabolites and lipids has been extensively recognized as early determinants of child health, but their contribution in CM and its pathobiology are poorly understood. This perspective provides a most recent update on these aspects. After briefly introducing the disciplines of metabolomics and lipidomics, we describe a mass spectrometry-based metabolic workflow for analysis of both metabolites and lipids and summarize several recent applications of metabolomics and lipidomics in CM. Finally, we discuss the future directions of the field toward the development of meaningful interventions for CM through metabolomics and lipidomics advances.

Prado EL, Larson LM, Cox K, Bettencourt K, Kubes JN, Shankar AH. Do effects of early life interventions on linear growth correspond to effects on neurobehavioural development? A systematic review and meta-analysis. Lancet Glob Health 2019; 7:e1398-e1413. [PMID: 31537370 DOI: 10.1016/s2214-109x(19)30361-4] [Citation(s) in RCA: 92] [Impact Index Per Article: 18.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Revised: 07/13/2019] [Accepted: 07/24/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Faltering in linear growth and neurobehavioural development during early childhood are often assumed to have common causes because of their consistent association. This notion has contributed to a global focus on the promotion of nutrition during pregnancy and childhood to improve both conditions. Our aim was to assess whether effects of interventions on linear growth are associated with effects on developmental scores and to quantify these associations. METHODS In this systematic review and meta-analysis, we included randomised trials done during pregnancy and in children aged 0-5 years that reported effects of any intervention on length-for-age or height-for-age Z scores (LAZ or HAZ) and on any of the following outcomes: motor, cognitive or mental, language, and social-emotional or behavioural development. We searched MEDLINE (Ovid), CINAHL (EBSCO), and PsycINFO (EBSCO) from database inception to June 25, 2019. Study-level data were extracted and, when required, authors were contacted for missing information. We calculated weighted meta-regression coefficients of the association between standardised effect sizes of interventions on LAZ or HAZ and developmental outcome scores and calculated pooled effect sizes for different types of intervention. FINDINGS Of the 7207 studies identified, we included 75 studies with 122 comparisons between intervention and control groups and outcomes reported for 72 275 children. Across all interventions, effect sizes on LAZ or HAZ were significantly associated with effect sizes on social-emotional scores (β 0·23, 95% CI 0·05 to 0·41; p=0·02), but not on cognitive (0·18, -0·36 to 0·72; p=0·51), language (0·12, -0·07 to 0·31; p=0·21), or motor development scores (0·23, -0·05 to 0·50; p=0·11). In studies that provided nutritional supplements, we observed positive significant pooled effect sizes on all five outcomes of LAZ or HAZ (effect size 0·05, 95% CI 0·01-0·09; p=0·01; n=50), cognitive or mental (0·06, 0·03-0·10; p<0·01; n=38), language (0·08, 0·03-0·13; p=0·01; n=21), motor (0·08, 0·04-0·12; p<0·01; n=41), and social-emotional (0·07, 0·02-0·12; p=0·01; n=20) scores. The effect sizes of nutritional supplementation on LAZ or HAZ scores were significantly associated with effect sizes on cognitive (β 0·40, 95% CI 0·04-0·77; p=0·049) and motor (0·43, 0·11-0·75; p=0·01) scores. In the 14 interventions promoting responsive care and learning opportunities, the pooled effect size on LAZ or HAZ score was not significant (-0·01, 95% CI -0·07 to 0·05; p=0·74), but pooled effect sizes on cognitive, language, and motor scores were 4 to 5 times larger (range 0·38-0·48) than the pooled effect sizes of nutritional supplementation (0·05-0·08). INTERPRETATION In nutritional supplementation interventions, improvements in linear growth were associated with small improvements in child development, whereas nurturing and stimulation interventions had significant effects on child development but no effects on linear growth. The determinants of linear growth and neurodevelopment are only partly shared. To nurture thriving individuals and communities, interventions should specifically target determinants of neurodevelopment and not simply linear growth.

Abstract
BACKGROUND Over the past two decades, Rwanda has experienced impressive economic growth, resulting in considerable improvements in living standards and poverty reduction. Despite these gains, progress on reducing the level of stunting in smallholder rural children, particularly boys, continues to be a serious concern. METHODS Policies, dietary diversity and socio-economic factors that may influence stunting in rural Rwandan children were evaluated using a logit model with clustered variance-covariance estimators based on village membership of the household. RESULTS Stunting of rural children was found to be multidimensionally related to the child's gender, weight and age; the dietary diversity, marriage status and education level of the head of household; mother's height; presence of a family garden or if they owned livestock; environmental factors such as altitude and soil fertility and location relative to a main road en route to a market; and a policy that promoted food production. CONCLUSIONS Findings suggest that agricultural policies may be subsidizing poor dietary behavior in that the aggregation of production encourages households to sell high quality nutritious food such as fruit and vegetables, for more voluminous amounts of nutritionally substandard goods, hence low dietary diversity. However, it is less clear if rural food markets are capable of supplying diverse and nutritious foods at affordable prices on a consistent basis, resulting in a lack of diversity and hence, low nutrient quality diets. Rwanda's next round of food security policies should focus on nutrition insecurity with special emphasis on the lack of protein, micronutrients and calories. Multipronged policies and programs focused on income growth, food security, enhanced access to markets and gender-related nutrition risks from inception through 2 years of age in the rural areas are required to improve rural household health outcomes, stunting in particular.

Association of Early Interventions With Birth Outcomes and Child Linear Growth in Low-Income and Middle-Income Countries: Bayesian Network Meta-analyses of Randomized Clinical Trials. JAMA Netw Open 2019; 2:e197871. [PMID: 31348509 PMCID: PMC6661710 DOI: 10.1001/jamanetworkopen.2019.7871] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Accepted: 05/29/2019] [Indexed: 12/24/2022] Open
Abstract
Importance The first 1000 days of life represent a critical window for child development. Pregnancy, exclusive breastfeeding (EBF) period (0-6 months), and complementary feeding (CF) period (6-24 months) have different growth requirements, so separate considerations for intervention strategies are needed. No synthesis to date has attempted to quantify the associations of interventions under multiple domains of micronutrient and balanced energy protein and food supplements, deworming, maternal education, water sanitation, and hygiene across these 3 life periods with birth and growth outcomes. Objective To determine the magnitude of association of interventions with birth and growth outcomes based on randomized clinical trials (RCTs) conducted in low-income and middle-income countries (LMICs) using Bayesian network meta-analyses. Data Sources MEDLINE, Embase, and Cochrane databases were searched from their inception up to August 14, 2018. Study Selection Included were LMIC-based RCTs of interventions provided to pregnant women, infants (0-6 months), and children (6-24 months). Data Extraction and Synthesis Two independent reviewers used a standardized data extraction and quality assessment form. Random-effects network meta-analyses were performed for each life period. Effect sizes are reported as odds ratios (ORs) and mean differences (MeanDiffs) for dichotomous and continuous outcomes, with 95% credible intervals (CrIs). This study calculated probabilities of interventions being superior to standard of care by at least a minimal clinically important difference. Main Outcomes and Measures The study compared ORs on preterm birth and MeanDiffs on birth weight for pregnancy, length for age (LAZ) for EBF, and height for age (HAZ) for CF. Results Among 302 061 participants in 169 randomized clinical trials, the network meta-analyses found several nutritional interventions that demonstrated greater association with improved birth and growth outcomes compared with standard of care. For instance, compared with standard of care, maternal supplements of multiple micronutrients showed reduced odds for preterm birth (OR, 0.54; 95% CrI, 0.27-0.97) and improved mean birth weight (MeanDiff, 0.08 kg; 95% CrI, 0.00-0.17 kg) but not LAZ during EBF (MeanDiff, -0.02; 95% CrI, -0.18 to 0.14). Supplementing infants and children with multiple micronutrients showed improved LAZ (MeanDiff, 0.20; 95% CrI, 0.03-0.35) and HAZ (MeanDiff, 0.14; 95% CrI, 0.02-0.25). The study found that pregnancy interventions generally had higher probabilities of a minimal clinically importance difference than the interventions for the EBF or CF in the first 1000 days of life. Conclusions and Relevance These analyses highlight the importance of intervening early for child development, during pregnancy if possible. Results of this study suggest that there is a need to combine interventions from multiple domains and test for their effectiveness as a package.

Abstract
BACKGROUND Nutritional interventions may affect child morbidity. OBJECTIVE The aim of this study was to examine whether providing lipid-based nutrient supplements (LNSs) to pregnant and lactating women or LNS or micronutrient powder (MNP) to their infants influences child morbidity. METHODS In a 4-arm cluster-randomized effectiveness trial, participants enrolled at ≤20 weeks of gestation (n = 4011) received: 1) maternal LNSs until 6 mo postpartum and child LNSs from 6-24 mo of age (LNS-LNS); 2) iron and folic acid (IFA) until 3 mo postpartum and child LNSs at 6-24 mo (IFA-LNS); 3) IFA (as above) and child MNP at 6-24 mo (IFA-MNP); or 4) IFA and no child supplement (IFA-Control). At 6, 12, 18, and 24 mo of age, we collected information on acute lower and upper respiratory infection (ALRI/AURI), diarrhea, and fever in the previous 14 d, and on episodes of illness in the previous 6 mo. RESULTS At 6 mo, prevalence of ALRI, fever, or diarrhea in the previous 14 d (17.6%, 18.9% and 6.8%, respectively) did not differ between infants of women who received LNS and infants of women who received IFA, but prevalence of AURI was lower in the LNS-LNS group than in all other groups combined (27.7% compared with 31.7%; OR: 0.83; 95% CI: 0.70, 0.99). At 12, 18, and 24 mo, the 4 arms did not differ in prevalence of fever (∼18.3%) or ALRI (≤15%) in the previous 14 d, but prevalence of AURI at 12 mo was lower in IFA-LNS than in IFA-Control infants (27.6% compared with 33.9%, OR: 0.74; 95% CI: 0.56, 0.99). The mean ± SD number of diarrhea episodes in the previous 6 mo was significantly higher among IFA-LNS than among IFA-Control infants at 6-12 (0.46 ± 0.04 compared with 0.33 ± 0.03) and 12-18 (0.45 ± 0.03 compared with 0.33 ± 0.02) mo. No other pairwise group differences were significant. CONCLUSION Providing LNSs to women or LNSs or MNP to children generally did not increase or decrease childhood illnesses. This trial was registered at clinicaltrials.gov as NCT01715038.

Abstract
BACKGROUND One nutritional intervention advocated to prevent malnutrition among children is lipid-based nutrient supplements (LNS). LNS provide a range of vitamins and minerals, but unlike most other micronutrient supplements, LNS also provide energy, protein and essential fatty acids. Alternative recipes and formulations to LNS include fortified blended foods (FBF), which are foods fortified with vitamins and minerals, and micronutrient powders (MNP), which are a combination of vitamins and minerals, OBJECTIVES: To assess the effects and safety of preventive LNS given with complementary foods on health, nutrition and developmental outcomes of non-hospitalised infants and children six to 23 months of age, and whether or not they are more effective than other foods (including FBF or MNP).This review did not assess the effects of LNS as supplementary foods or therapeutic foods in the management of moderate and severe acute malnutrition. SEARCH METHODS In October 2018, we searched CENTRAL, MEDLINE, Embase, 21 other databases and two trials registers for relevant studies. We also checked the reference lists of included studies and relevant reviews and contacted the authors of studies and other experts in the area for any ongoing and unpublished studies. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs that evaluated the impact of LNS plus complementary foods given at point-of-use (for any dose, frequency, duration) to non-hospitalised infants and young children aged six to 23 months in stable or emergency settings and compared to no intervention, other supplementary foods (i.e. FBF), nutrition counselling or multiple micronutrient supplements or powders for point-of-use fortification of complementary foods. DATA COLLECTION AND ANALYSIS Two review authors independently screened studies for relevance and, for those studies included in the review, extracted data, assessed risk of bias and rated the quality of the evidence using the GRADE approach. We carried out statistical analysis using Review Manager software. We used a random-effects meta-analysis for combining data as the interventions differed significantly. We set out the main findings of the review in 'Summary of findings' tables,. MAIN RESULTS Our search identified a total of 8124 records, from which we included 17 studies (54 papers) with 23,200 children in the review. The included studies reported on one or more of the pre-specified primary outcomes, and five studies included multiple comparison groups.Overall, the majority of trials were at low risk of bias for random sequence generation, allocation concealment, blinding of outcome assessment, incomplete outcome data, selective reporting and other sources of bias, but at high risk of bias for blinding of participants and personnel due to the nature of the intervention. Using the GRADE approach, we judged the quality of the evidence for most outcomes as low or moderate.LNS+complementary feeding compared with no intervention Thirteen studies compared LNS plus complementary feeding with no intervention. LNS plus complementary feeding reduced the prevalence of moderate stunting by 7% (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.88 to 0.98; nine studies, 13,372 participants; moderate-quality evidence), severe stunting by 15% (RR 0.85, 95% CI 0.74 to 0.98; five studies, 6151 participants; moderate-quality evidence), moderate wasting by 18% (RR 0.82, 95% CI 0.74 to 0.91; eight studies; 13,172 participants; moderate-quality evidence), moderate underweight by 15% (RR 0.85, 95% CI 0.80 to 0.91; eight studies, 13,073 participants; moderate-quality evidence), and anaemia by 21% (RR 0.79, 95% CI 0.69 to 0.90; five studies, 2332 participants; low-quality evidence). There was no impact of LNS plus complementary feeding on severe wasting (RR 1.27, 95% CI 0.66 to 2.46; three studies, 2329 participants) and severe underweight (RR 0.78, 95%CI 0.54 to 1.13; two studies, 1729 participants). Adverse effects did not differ between the groups (RR 0.86, 95% CI 0.74 to 1.01; three studies, 3382 participants).LNS+complementary feeding compared with FBF Five studies compared LNS plus complementary feeding with other FBF, including corn soy blend and UNIMIX. We pooled four of the five studies in meta-analyses and found that, when compared to other FBF, LNS plus complementary feeding significantly reduced the prevalence of moderate stunting (RR 0.89, 95% CI 0.82 to 0.97; three studies, 2828 participants; moderate-quality evidence), moderate wasting (RR 0.79, 95% CI 0.65 to 0.97; two studies, 2290 participants; moderate-quality evidence), and moderate underweight (RR 0.81, 95% CI 0.73 to 0.91; two studies, 2280 participants; moderate-quality evidence). We found no difference between LNS plus complementary feeding and FBF for severe stunting (RR 0.41, 95% CI 0.12 to 1.42; two studies, 729 participants; low-quality evidence), severe wasting (RR 0.64, 95% CI 0.19 to 2.81; two studies, 735 participants; moderate-quality evidence), and severe underweight (RR 1.23, 95% CI 0.67 to 2.25; one study, 173 participants; low-quality evidence).LNS+complementary feeding compared with MNP Four studies compared LNS plus complementary feeding with MNP. We pooled data from three of the four studies in meta-analyses and found that compared to MNP, LNS plus complementary feeding significantly reduced the prevalence of moderate underweight (RR 0.88, 95% CI 0.78 to 0.99; two studies, 2004 participants; moderate-quality evidence) and anaemia (RR 0.38, 95% CI 0.21 to 0.68; two studies, 557 participants; low-quality evidence). There was no difference between LNS plus complementary feeding and MNP for moderate stunting (RR 0.92, 95% CI 0.82 to 1.02; three studies, 2365 participants) and moderate wasting (RR 0.97, 95% CI 0.77 to 1.23; two studies, 2004 participants). AUTHORS' CONCLUSIONS The findings of this review suggest that LNS plus complementary feeding compared to no intervention is effective at improving growth outcomes and anaemia without adverse effects among children aged six to 23 months in low- and middle-income countries (LMIC) in Asia and Africa, and more effective if provided over a longer duration of time (over 12 months). Limited evidence also suggests that LNS plus complementary feeding is more effective than FBF and MNP at improving growth outcomes.

Abstract
BACKGROUND Few studies have evaluated the long-term effects of nutritional supplementation during the first 1000 d of life. We previously reported that maternal and child lipid-based nutrient supplements (LNS) increased child length by 18 mo. OBJECTIVE The aim of this study was to examine the effects of LNS on later growth and body composition at 4-6 y of age. DESIGN This was a follow-up of children in the International Lipid-based Nutrient Supplements (iLiNS)-DYAD trial in Ghana. Women (n = 1320) at ≤20 weeks of gestation were randomly assigned to: 1) iron and folic acid during pregnancy and 200 mg calcium/d for 6 mo postpartum, 2) multiple micronutrients (1-2 RDA of 18 vitamins and minerals) during both periods, or 3) maternal LNS during both periods plus child LNS from 6 to 18 mo. At 4-6 y, we compared height, height-for-age z score (HAZ), and % body fat (deuterium dilution method) between the LNS group and the 2 non-LNS groups combined. RESULTS Data were available for 961 children (76.5% of live births). There were no significant differences between LNS compared with non-LNS groups in height [106.7 compared with 106.3 cm (mean difference, MD, 0.36; P = 0.226)], HAZ [-0.49 compared with -0.57 (MD = 0.08; P = 0.226)], stunting (< -2 SD) [6.5 compared with 6.3% (OR = 1.00; P = 0.993)], or % body fat [15.5 compared with 15.3% (MD = 0.16; P = 0.630)]. However, there was an interaction with maternal prepregnancy BMI (kg/m2) (P-interaction = 0.046 before correction for multiple testing): among children of women with BMI < 25 , LNS children were taller than non-LNS children (+1.1 cm, P = 0.017), whereas there was no difference among children of women with BMI ≥ 25 (+0.1 cm; P = 0.874). CONCLUSIONS There was no overall effect of LNS on height at 4-6 y in this cohort, which had a low stunting rate, but height was greater in the LNS group among children of nonoverweight/obese women. There was no adverse impact of LNS on body composition. This trial was registered at clinicaltrials.gov as NCT00970866.

Exposure to a slightly sweet lipid-based nutrient supplement during early life does not increase the level of sweet taste most preferred among 4- to 6-year-old Ghanaian children: follow-up of a randomized controlled trial. Am J Clin Nutr 2019; 109:1224-1232.

Abstract
BACKGROUND The impact of feeding a slightly sweet nutrient supplement early in life on later sweet taste preference is unknown. OBJECTIVE We tested the hypothesis that the level of sucrose most preferred by 4-6-y-old children exposed to a slightly sweet lipid-based nutrient supplement (LNS) early in life would not be higher than that of children never exposed to LNS. DESIGN We followed up children born to women (n = 1,320) who participated in a randomized trial in Ghana. In one group, LNS was provided to women on a daily basis during pregnancy and the first 6 mo postpartum and to their infants from age 6 to 18 mo (LNS group). The control groups received daily iron and folic acid or multiple micronutrients during pregnancy and the first 6 mo postpartum, with no infant supplementation (non-LNS group). At age 4-6 y, we randomly selected a subsample of children (n = 775) to assess the concentration of sucrose most preferred using the Monell 2-series, forced-choice, paired-comparison tracking procedure. We compared LNS with non-LNS group differences using a noninferiority margin of 5% weight/volume (wt/vol). RESULTS Of the 624 children tested, most (61%) provided reliable responses. Among all children, the mean ± SD sucrose solution most preferred (% wt/vol) was 14.6 ± 8.6 (LNS group 14.9 ± 8.7; non-LNS group 14.2 ± 8.4). However, among children with reliable responses, it was 17.0 ± 10.2 (LNS group 17.5 ± 10.4; non-LNS group 16.5 ± 10.0). The upper level of the 95% CI of the difference between groups did not exceed the noninferiority margin in either the full sample or those with reliable responses, indicating that the LNS group did not have a higher sweet preference than the non-LNS group. CONCLUSION Exposure to a slightly sweet nutrient supplement early in life did not increase the level of sweet taste most preferred during childhood. This trial was registered at clinicaltrials.gov as NCT00970866.

Abstract
A child’s endowment is a reflection of his/her genetic makeup and the conditions faced in early life. Parents build on their child’s endowment by investing resources in their child, and together, a child’s endowment and subsequent investments act as input into important later-life outcomes. A positive or negative shock to a child’s endowment can have a direct biological effect on a child’s long-term outcomes but may also affect parents’ decisions about investments in the health and human capital of their children. Using follow-up data collected several years after a randomized trial in Ghana, we explored whether maternal and child supplementation with small-quantity lipid-based nutrient supplements (SQ-LNS) throughout much of the first 1,000 days influenced parental investments in the health and human capital of their children. Across the domains of family planning, breastfeeding, health, education, and paternal financial support, we found that, in general, the intervention did not affect investments in the treated child nor his/her untreated siblings. These results suggest that given production technologies, constraints, and preferences, the intervention either did not change parents’ optimal investment strategies or that the effects of the intervention, namely increased birth size and attained length at 18 months of age, were too small for parents to perceive or to have any meaningful impact on parents’ expectations about the returns to investments in their children.

Abstract
BACKGROUND Multiple-micronutrient (MMN) deficiencies often coexist among women of reproductive age in low- and middle-income countries. They are exacerbated in pregnancy due to the increased demands of the developing fetus, leading to potentially adverse effects on the mother and baby. A consensus is yet to be reached regarding the replacement of iron and folic acid supplementation with MMNs. Since the last update of this Cochrane Review in 2017, evidence from several trials has become available. The findings of this review will be critical to inform policy on micronutrient supplementation in pregnancy. OBJECTIVES To evaluate the benefits of oral multiple-micronutrient supplementation during pregnancy on maternal, fetal and infant health outcomes. SEARCH METHODS For this 2018 update, on 23 February 2018 we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP), and reference lists of retrieved studies. We also contacted experts in the field for additional and ongoing trials. SELECTION CRITERIA All prospective randomised controlled trials evaluating MMN supplementation with iron and folic acid during pregnancy and its effects on pregnancy outcomes were eligible, irrespective of language or the publication status of the trials. We included cluster-randomised trials, but excluded quasi-randomised trials. Trial reports that were published as abstracts were eligible. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS We identified 21 trials (involving 142,496 women) as eligible for inclusion in this review, but only 20 trials (involving 141,849 women) contributed data. Of these 20 trials, 19 were conducted in low- and middle-income countries and compared MMN supplements with iron and folic acid to iron, with or without folic acid. One trial conducted in the UK compared MMN supplementation with placebo. In total, eight trials were cluster-randomised.MMN with iron and folic acid versus iron, with or without folic acid (19 trials)MMN supplementation probably led to a slight reduction in preterm births (average risk ratio (RR) 0.95, 95% confidence interval (CI) 0.90 to 1.01; 18 trials, 91,425 participants; moderate-quality evidence), and babies considered small-for-gestational age (SGA) (average RR 0.92, 95% CI 0.88 to 0.97; 17 trials; 57,348 participants; moderate-quality evidence), though the CI for the pooled effect for preterm births just crossed the line of no effect. MMN reduced the number of newborn infants identified as low birthweight (LBW) (average RR 0.88, 95% CI 0.85 to 0.91; 18 trials, 68,801 participants; high-quality evidence). We did not observe any differences between groups for perinatal mortality (average RR 1.00, 95% CI 0.90 to 1.11; 15 trials, 63,922 participants; high-quality evidence). MMN supplementation led to slightly fewer stillbirths (average RR 0.95, 95% CI 0.86 to 1.04; 17 trials, 97,927 participants; high-quality evidence) but, again, the CI for the pooled effect just crossed the line of no effect. MMN supplementation did not have an important effect on neonatal mortality (average RR 1.00, 95% CI 0.89 to 1.12; 14 trials, 80,964 participants; high-quality evidence). We observed little or no difference between groups for the other maternal and pregnancy outcomes: maternal anaemia in the third trimester (average RR 1.04, 95% CI 0.94 to 1.15; 9 trials, 5912 participants), maternal mortality (average RR 1.06, 95% CI 0.72 to 1.54; 6 trials, 106,275 participants), miscarriage (average RR 0.99, 95% CI 0.94 to 1.04; 12 trials, 100,565 participants), delivery via a caesarean section (average RR 1.13, 95% CI 0.99 to 1.29; 5 trials, 12,836 participants), and congenital anomalies (average RR 1.34, 95% CI 0.25 to 7.12; 2 trials, 1958 participants). However, MMN supplementation probably led to a reduction in very preterm births (average RR 0.81, 95% CI 0.71 to 0.93; 4 trials, 37,701 participants). We were unable to assess a number of prespecified, clinically important outcomes due to insufficient or non-available data.When we assessed primary outcomes according to GRADE criteria, the quality of evidence for the review overall was moderate to high. We graded the following outcomes as high quality: LBW, perinatal mortality, stillbirth, and neonatal mortality. The outcomes of preterm birth and SGA we graded as moderate quality; both were downgraded for funnel plot asymmetry, indicating possible publication bias.We carried out sensitivity analyses excluding trials with high levels of sample attrition (> 20%). We found that results were consistent with the main analyses for all outcomes. We explored heterogeneity through subgroup analyses by maternal height, maternal body mass index (BMI), timing of supplementation, dose of iron, and MMN supplement formulation (UNIMMAP versus non-UNIMMAP). There was a greater reduction in preterm births for women with low BMI and among those who took non-UNIMMAP supplements. We also observed subgroup differences for maternal BMI and maternal height for SGA, indicating greater impact among women with greater BMI and height. Though we found that MMN supplementation made little or no difference to perinatal mortality, the analysis demonstrated substantial statistical heterogeneity. We explored this heterogeneity using subgroup analysis and found differences for timing of supplementation, whereby higher impact was observed with later initiation of supplementation. For all other subgroup analyses, the findings were inconclusive.MMN versus placebo (1 trial)A single trial in the UK found little or no important effect of MMN supplementation on preterm births, SGA, or LBW but did find a reduction in maternal anaemia in the third trimester (RR 0.66, 95% CI 0.51 to 0.85), when compared to placebo. This trial did not measure our other outcomes. AUTHORS' CONCLUSIONS Our findings suggest a positive impact of MMN supplementation with iron and folic acid on several birth outcomes. MMN supplementation in pregnancy led to a reduction in babies considered LBW, and probably led to a reduction in babies considered SGA. In addition, MMN probably reduced preterm births. No important benefits or harms of MMN supplementation were found for mortality outcomes (stillbirths, perinatal and neonatal mortality). These findings may provide some basis to guide the replacement of iron and folic acid supplements with MMN supplements for pregnant women residing in low- and middle-income countries.

Maternal-Infant Supplementation with Small-Quantity Lipid-Based Nutrient Supplements Does Not Affect Child Blood Pressure at 4-6 Y in Ghana: Follow-up of a Randomized Trial. J Nutr 2019; 149:522-531. [PMID: 30753625 PMCID: PMC6398380 DOI: 10.1093/jn/nxy285] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Revised: 07/23/2018] [Accepted: 10/15/2018] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND In the International Lipid-Based Nutrient Supplements (iLiNS)-DYAD-Ghana trial, prenatal small-quantity lipid-based nutrient supplements (LNSs) had a positive effect on birth weight. Birth weight may be inversely related to blood pressure (BP) later in life. OBJECTIVES We examined the effect of the intervention on BP at 4-6 y of age, and maternal and child factors related to BP. METHODS The iLiNS-DYAD-Ghana study was a partially double-blind, randomized controlled trial which assigned women (n = 1320) ≤20 weeks of gestation to daily supplementation with: 1) iron and folic acid during pregnancy and 200 mg Ca for 6 mo postpartum , 2) multiple micronutrients during pregnancy and postpartum, or 3) LNSs during pregnancy and postpartum plus LNSs for infants from 6 to 18 mo of age. At 4-6 y of age (n = 858, 70% of live births), we compared BP, a secondary outcome, between non-LNS and LNS groups and examined whether BP was related to several factors including maternal BP, child weight-for-age z score (WAZ), and physical activity. RESULTS Non-LNS and LNS groups did not differ in systolic (99.2 ± 0.4 compared with 98.5 ± 0.6 mm Hg; P = 0.317) or diastolic (60.1 ± 0.3 compared with 60.0 ± 0.4 mm Hg; P = 0.805) BP, or prevalence of high BP (systolic or diastolic BP ≥90th percentile of the US National Heart, Lung, and Blood Institute reference: 31% compared with 28%; P = 0.251). BP at 4-6 y of age was positively related to birth weight; this relation was largely mediated through concurrent WAZ in a path model. Concurrent WAZ and maternal BP were the factors most strongly related to child BP. CONCLUSIONS Despite greater birth weight in the LNS group, there was no intervention group difference in BP at 4-6 y. In this preschool population at high risk of adult hypertension based on BP at 4-6 y, high maternal BP and child WAZ were key factors related to BP. This trial was registered at clinicaltrials.gov as NCT00970866.

J Nutr 2019; 149:532-541.

Abstract
BACKGROUND Whether consuming sweet foods early in life affects sweet food preferences and consumption later in childhood is unknown. OBJECTIVE We tested the hypothesis that exposure to a slightly sweet lipid-based nutrient supplement (LNS) early in life would not increase preference for or consumption of sweet items at preschool age. METHODS We followed up children who had participated in a randomized trial in Ghana in which LNS was provided to 1 group of women during pregnancy and 6 mo postpartum and to their infants from ages 6-18 mo (LNS group). The control group (non-LNS group) received iron and folic acid during pregnancy or multiple micronutrients during pregnancy and 6 mo postpartum, with no infant supplementation. At 4-6 y, we obtained data from caregivers on children's food and beverage preferences and consumption (n = 985). For a randomly selected subsample (n = 624), we assessed preference for sweet items using a photo game (range in potential scores, 0-15). For the photo game and reported consumption of sweet items, we examined group differences using predetermined noninferiority margins equivalent to an effect size of 0.2. RESULTS Median (quartile 1, quartile 3) reported consumption of sweet items (times in previous week) was 14 (8, 23) in the LNS group and 16 (9, 22) in the non-LNS group; in the photo game, the number of sweet items selected was 15 (11, 15) and 15 (11, 15), respectively. The upper level of the 95% CI of the mean difference between LNS and non-LNS groups did not exceed the noninferiority margins for these outcomes. Caregiver-reported preferences for sweet items also did not differ between groups (P = 0.9). CONCLUSION In this setting, where child consumption of sweet foods was common, exposure to a slightly sweet LNS early in life did not increase preference for or consumption of sweet foods and beverages at preschool age. This trial was registered at clinicaltrials.gov as NCT00970866.

Abstract
Background Adequate nutrition is necessary for brain development during pregnancy and infancy. Few randomized controlled trials of supplementation during these periods have measured later developmental outcomes. Objective Our objective was to investigate the effects of provision of prenatal and postnatal lipid-based nutrient supplements (LNS) on child development at preschool age. Methods We conducted a follow-up study of 966 children aged 4-6 y in 2016, born to women who participated in the International Lipid-Based Nutrient Supplements-DYAD trial conducted in Ghana in 2009-2014, representing 79% of eligible children. Women ≤20 weeks of gestation were randomized to daily LNS or multiple micronutrient (MMN) capsules during pregnancy through 6 mo postpartum or iron and folic acid (IFA) capsules during pregnancy and calcium placebo capsules during 6 mo postpartum. Children in the LNS group received LNS from 6 to 18 mo. Primary outcomes of this follow-up study were (1) a cognitive factor score based on a test battery adapted from several standard tests, 2) fine motor score (9-hole pegboard test), and (3) social-emotional difficulties (Strengths and Difficulties Questionnaire; SDQ). Eight secondary outcomes were calculated in specific domains (e.g., language, SDQ prosocial). Analysis was by a complete case intention to treat in a 2-group comparison: LNS compared with non-LNS (MMN + IFA). Results Children in the LNS group had significantly lower social-emotional difficulties z-scores than children in the non-LNS group (adjusted for child age β = -0.12, 95% CI: -0.25, 0.02, P = 0.087; fully adjusted β = -0.16, 95% CI: -0.29, -0.03, P = 0.013). The effect of LNS on social-emotional difficulties score was larger among children living in households with lower home environment scores (P-interaction = 0.081). No other outcomes differed between the 2 intervention groups. Conclusions Provision of LNS during the first 1000 d of development improved behavioral function, particularly for children from low nurturing and stimulation households, but did not affect cognition at preschool age in this setting. Trial Registration: clinicaltrials.gov, Identifier NCT00970866.

Path analyses of risk factors for linear growth faltering in four prospective cohorts of young children in Ghana, Malawi and Burkina Faso. BMJ Glob Health 2019; 4:e001155.

Abstract
Stunting prevalence is an indicator of a country’s progress towards United Nations’ Sustainable Development Goal 2, which is to end hunger and achieve improved nutrition. Accelerating progress towards reducing stunting requires a deeper understanding of the factors that contribute to linear growth faltering. We conducted path analyses of factors associated with 18-month length-for-age z-score (LAZ) in four prospective cohorts of children who participated in trials conducted as part of the International Lipid-Based Nutrient Supplements Project in Ghana (n=1039), Malawi (n=684 and 1504) and Burkina Faso (n=2619). In two cohorts, women were enrolled during pregnancy. In two other cohorts, infants were enrolled at 6 or 9 months. We examined the association of 42 indicators of environmental, maternal, caregiving and child factors with 18-month LAZ. Using structural equation modelling, we examined direct and indirect associations through hypothesised mediators in each cohort. Out of 42 indicators, 2 were associated with 18-month LAZ in three or four cohorts: maternal height and body mass index (BMI). Six factors were associated with 18-month LAZ in two cohorts: length for gestational age z-score (LGAZ) at birth, pregnancy duration, improved household water, child dietary diversity, diarrhoea incidence and 6-month or 9-month haemoglobin concentration. Direct associations were more prevalent than indirect associations, but 30%–62% of the associations of maternal height and BMI with 18-month LAZ were mediated by LGAZ at birth. Factors that were not associated with LAZ were maternal iron status, illness and inflammation during pregnancy, maternal stress and depression, exclusive breast feeding during 6 months post partum, feeding frequency and child fever, malaria and acute respiratory infections. These findings may help in identifying interventions to accelerate progress towards reducing stunting; however, much of the variance in linear growth status remained unaccounted for by these 42 individual-level factors, suggesting that community-level changes may be needed to achieve substantial progress.

Effect of small-quantity lipid-based nutrient supplements on growth, psychomotor development, iron status, and morbidity among 6- to 12-mo-old infants in South Africa: a randomized controlled trial. Am J Clin Nutr 2019; 109:55-68. [PMID: 30649163 PMCID: PMC6358035 DOI: 10.1093/ajcn/nqy282] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Accepted: 09/18/2018] [Indexed: 01/14/2023] Open
Abstract
Background Evidence on the effect of small-quantity lipid-based nutrient supplements (SQ-LNSs) on early child growth and development is mixed. Objective This study assessed the effect of daily consumption of 2 different SQ-LNS formulations on linear growth (primary outcome), psychomotor development, iron status (secondary outcomes), and morbidity in infants from age 6 to 12 mo within the context of a maize-based complementary diet. Methods Infants (n = 750) were randomly assigned to receive SQ-LNS, SQ-LNS-plus, or no supplement. Both SQ-LNS products contained micronutrients and essential fatty acids. SQ-LNS-plus contained, in addition, docosahexaenoic acid, arachidonic acid (important for brain and eye development), lysine (limiting amino acid in maize), phytase (enhances iron absorption), and other nutrients. Infants' weight and length were measured bimonthly. At age 6 and 12 mo, psychomotor development using the Kilifi Developmental Inventory and South African Parent Rating Scale and hemoglobin, plasma ferritin, C-reactive protein, and α1-acid glycoprotein were assessed. WHO Motor Milestone outcomes, adherence, and morbidity were monitored weekly through home visits. Primary analysis was by intention-to-treat, comparing each SQ-LNS group with the control. Results SQ-LNS-plus had a positive effect on length-for-age zscore at age 8 mo (mean difference: 0.11; 95% CI: 0.01, 0.22; P = 0.032) and 10 mo (0.16; 95% CI: 0.04, 0.27; P = 0.008) but not at 12 mo (0.09; 95% CI: -0.02, 0.21; P = 0.115), locomotor development score (2.05; 95% CI: 0.72, 3.38; P = 0.003), and Parent Rating Score (1.10; 95% CI: 0.14, 2.07; P = 0.025), but no effect for weight-for-age zscore. Both SQ-LNS (P = 0.027) and SQ-LNS-plus (P = 0.005) improved hemoglobin concentration and reduced the risk of anemia, iron deficiency, and iron-deficiency anemia. Both SQ-LNS products reduced longitudinal prevalence of fever, coughing, and wheezing but increased incidence and longitudinal prevalence of diarrhea, vomiting, and rash/sores. Conclusions Point-of-use fortification with SQ-LNS-plus showed an early transient effect on linear growth and improved locomotor development. Both SQ-LNS products had positive impacts on anemia and iron status. This trial was registered at clinicaltrials.gov as NCT01845610.

J Nutr 2019; 149:149-158. [PMID: 30624674 PMCID: PMC6351141 DOI: 10.1093/jn/nxy225] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2018] [Accepted: 08/10/2018] [Indexed: 11/17/2022] Open
Abstract
Background Interventions are needed to address iron deficiency in low-income settings. Objective This secondary outcome analysis aimed to compare the hemoglobin (Hb) and iron status [zinc protoporphyrin (ZPP)] of children born to women enrolled in the iLiNS-DYAD trial in Ghana. Methods Women ≤20 wk pregnant (n = 1320) were assigned to receive 60 mg Fe/d and 400 µg folic acid/d until delivery and placebo thereafter, and no supplementation for infants (IFA group); or multiple micronutrients containing 20 mg Fe/d until 6 mo postpartum and no supplementation for infants (MMN); or small-quantity lipid-based nutrient supplements (SQ-LNSs) containing 20 mg Fe/d until 6 mo postpartum, and SQ-LNSs for infants from 6 to 18 mo of age (LNS). We compared infants' Hb (g/L) and ZPP (µmol/mol heme) at 6 and 18 mo of age. Results At 6 mo of age, groups did not differ in mean ± SD Hb (overall: 113 ± 9.9 g/L) or geometric mean (95% CI) ZPP [overall: 62.6 (60.6, 64.7)]. At 18 mo of age, mean ± SD Hb (overall: 112 ± 10.4 g/L) did not differ significantly between groups, whereas geometric mean (95% CI) ZPP was lower (P = 0.031) in the LNS group [53.9 (50.7, 57.3)] than the IFA [60.4 (56.7, 64.3)] but not the MMN [58.8 (55.6, 62.2)] group. Further, the LNS group, compared with the IFA and MMN groups combined, had a lower prevalence of elevated (>70) ZPP (27.5% compared with 35%; P = 0.02) and a marginally lower prevalence of anemia (38.7% compared with 44.9%; P = 0.06). These results generally remained unchanged when controlling for prespecified covariates or correcting for inflammation. Conclusions In this setting, providing SQ-LNSs or multiple micronutrients with 20 mg Fe/d, compared with iron (60 mg/d) and folic acid, to pregnant women does not affect their infants' Hb or iron status at 6 mo of age, but maternal and infant supplementation with SQ-LNSs increases infants' iron status at 18 mo of age. This trial was registered at clinicaltrials.gov as NCT00970866.

Abstract
Poor infant and young child feeding (IYCF) practices are associated with linear growth faltering. Our objective was to evaluate the impact of a nutrition and water and sanitation for health intervention on three IYCF indicators-minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum acceptable diet (MAD) in Kenyan children. Households were randomized into one of eight groups: (a) active control; (b) passive control; (c) water quality (W); (d) sanitation (S); (e) handwashing (H); (f) combined Water, Sanitation, and Handwashing; (g) nutrition (N); and (h) combined WSH + N. In the N and WSH + N arms, community-based promoters counselled households on optimal IYCF practices, and small-quantity lipid-based nutrient supplements (SQ-LNS) were provided to children 6-24 months of age. Twelve months (Year 1) and 24 months (Year 2) after interventions began, enumerators surveyed mothers to ascertain IYCF practices. We made pairwise comparisons of each intervention arm versus the active control arm using log binomial models. In total, 3,652 caretakers were surveyed at Year 1 and 4,987 caretakers at Year 2. Compared with the active control, there were no differences in any of the arms in MDD, MMF, or MAD, aside from an increase in MDD at Year 1 in the nutrition only arm but not in the combined WSH + N arm (N: 68%; WSH + N: 61%; C: 61%; N arm prevalence ratio: 1.13 95% CI [1.01, 1.25]). In this setting, a nutrition behaviour change communication intervention had little impact on IYCF indicators. The provision of SQ-LNS was not detrimental to current IYCF indicators in the community.

Abstract
Background Food-assisted maternal and child health and nutrition (FA-MCHN) programs may foster child growth during the first 1000 d (pregnancy and the first 2 y of a child's life), but evidence is scant. Objective We evaluated the impact of an FA-MCHN program, PROCOMIDA, on linear growth (stunting [length-for-age z score (LAZ) < -2] and length-for-age difference [LAD]) among children aged 1-24 mo. PROCOMIDA was implemented in Guatemala by Mercy Corps and was available to beneficiaries throughout the first 1000 d. Methods We used a longitudinal, cluster-randomized controlled trial with groups varying in family ration sizes [full (FFR), reduced (RFR), and none (NFR)] and individual ration types provided to mothers (pregnancy to 6 mo postpartum) and children (6-24 mo of age) [corn-soy blend (CSB), lipid-based nutrient supplement (LNS), micronutrient powder (MNP)]: 1) FFR + CSB (n = 576); 2) RFR + CSB (n = 575); 3) NFR + CSB (n = 542); 4) FFR + LNS (n = 550); 5) FFR + MNP (n = 587); 6) control (n = 574). Program impacts compared with control, and differential impacts between groups varying family ration size or individual ration type, were assessed through the use of linear mixed-effects models and post hoc simple effect tests (significant if P < 0.05). Results PROCOMIDA significantly reduced stunting at age 1 mo in FFR + CSB, RFR + CSB, and FFR + MNP groups compared with control [5.05, 4.06, and 3.82 percentage points (pp), respectively]. Stunting impact increased by age 24 mo in FFR + CSB and FFR + MNP relative to control (impact = 11.1 and 6.5 pp at age 24 mo, respectively). For CSB recipients, the FFR compared with RFR or NFR significantly reduced stunting (6.47-9.68 pp). CSB reduced stunting significantly more than LNS at age 24 mo (8.12 pp). Conclusions FA-MCHN programs can reduce stunting during the first 1000 d, even in relatively energy/food-secure populations. Large family rations with individual rations of CSB or MNP were most effective. The widening of impact as children age highlights the importance of intervening throughout the full first 1000 d. This trial was registered at clinicaltrials.gov as NCT01072279.

Abstract
BACKGROUND Ready-to-use lipid-based nutrient supplements (LNS) are a highly nutrient-dense supplement, which could be a good source of macro- and micronutrients for pregnant women who need to supplement their nutrient intake. OBJECTIVES To assess the effects of LNS for maternal, birth and infant outcomes in pregnant women. Secondary objectives were to explore the most appropriate composition, frequency and duration of LNS administration. SEARCH METHODS In May 2018, we searched CENTRAL, MEDLINE, Embase, 22 other databases and two trials registers for any published and ongoing studies. We also checked the reference lists of included studies and relevant reviews, and we contacted the authors of included studies and other experts in the field to identify any studies we may have missed, including any unpublished studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs that compared LNS given in pregnancy to no intervention, placebo, iron folic acid (IFA), multiple micronutrients (MMN) or nutritional counselling. DATA COLLECTION AND ANALYSIS We used standard Cochrane procedures. MAIN RESULTS We included four studies in 8018 pregnant women. All four studies took place in stable community settings in low- and middle-income countries: Bangladesh, Burkina Faso, Ghana and Malawi. None were in emergency settings. The oldest trial was published in 2009. Of the four included studies, one compared LNS to IFA, one compared LNS to MMN, and two compared LNS to both IFA and MMN.We considered the included studies to be of medium to high quality, and we rated the quality of the evidence as moderate using the GRADE approach.LNS versus IFAMaternal outcomes: there was no difference between the LNS and IFA groups as regards maternal gestational weight gain per week (standard mean difference (SMD) 0.46, 95% confidence interval (CI) -0.44 to 1.36; 2 studies, 3539 participants). One study (536 participants) showed a two-fold increase in the prevalence of maternal anaemia in the LNS group compared to the IFA group, but no difference between the groups as regards adverse effects. There was no difference between the two groups for maternal mortality (risk ratio (RR) 0.53, 95% CI 0.12 to 2.41; 3 studies, 5628 participants).Birth and infant outcomes: there was no difference between the LNS and IFA groups for low birth weight (LBW) (RR 0.87, 95% CI 0.72 to 1.05; 3 studies, 4826 participants), though newborns in the LNS group had a slightly higher mean birth weight (mean difference (MD) 53.28 g, 95% CI 28.22 to 78.33; 3 studies, 5077 participants) and birth length (cm) (MD 0.24 cm, 95% CI 0.11 to 0.36; 3 studies, 4986 participants). There was a reduction in the proportion of infants who were small for gestational age (SGA) (RR 0.94, 95% CI 0.89 to 0.99; 3 studies, 4823 participants) and had newborn stunting (RR 0.82, 95% CI 0.71 to 0.94; 2 studies, 4166 participants) in the LNS group, but no difference between the LNS and IFA groups for preterm delivery (RR 0.94, 95% CI 0.80 to 1.11; 4 studies, 4924 participants), stillbirth (RR 1.14; 95% CI 0.52 to 2.48; 3 studies, 5575 participants) or neonatal death (RR 0.96, 95% CI 0.14 to 6.51). The current evidence for child developmental outcomes is not sufficient to draw any firm conclusions.LNS versus MMNMaternal outcomes: one study (662 participants) showed no difference between the LNS and MMN groups as regards gestational weight gain per week or adverse effects. Another study (557 participants) showed an increased risk of maternal anaemia in the LNS group compared to the MMN group.Birth and infant outcomes: there was no difference between the LNS and MMN groups for LBW (RR 0.92, 95% CI 0.74 to 1.14; 3 studies, 2404 participants), birth weight (MD 23.67 g, 95% CI -10.53 to 57.86; 3 studies, 2573 participants), birth length (MD 0.20 cm, 95% CI -0.02 to 0.42; 3 studies, 2567 participants), SGA (RR 0.95, 95% CI 0.84 to 1.07; 3 studies, 2393 participants), preterm delivery (RR 1.15, 95% CI 0.93 to 1.42; 3 studies, 2630 participants), head circumference z score (MD 0.10, 95% CI -0.01 to 0.21; 2 studies, 1549 participants) or neonatal death (RR 0.88, 95% CI 0.36 to 2.15; 1 study, 1175 participants). AUTHORS' CONCLUSIONS Findings from this review suggest that LNS supplementation has a slight, positive effect on weight at birth, length at birth, SGA and newborn stunting compared to IFA. LNS and MMN were comparable for all maternal, birth and infant outcomes. Both IFA and MMN were better at reducing maternal anaemia when compared to LNS. We did not find any trials for LNS given to pregnant women in emergency settings.Readers should interpret the beneficial findings of the review with caution since the evidence comes from a small number of trials, with one-large scale study (conducted in community settings in Bangladesh) driving most of the impact. In addition, effect sizes are too small to propose any concrete recommendation for practice.

Prenatal and Postnatal Supplementation with Lipid-Based Nutrient Supplements Reduces Anemia and Iron Deficiency in 18-Month-Old Bangladeshi Children: A Cluster-Randomized Effectiveness Trial. J Nutr 2018; 148:1167-1176.

Abstract
Background Anemia, iron deficiency (ID), and iron deficiency anemia (IDA) among young children are public health concerns in developing countries. Objective We evaluated the effects of small-quantity lipid-based nutrient supplements (LNSs) and micronutrient powder (MNP) on anemia, ID, and IDA in 18-mo-old Bangladeshi children. Methods We enrolled 4011 pregnant women in a cluster-randomized effectiveness trial with 4 arms-1) LNS-LNS: LNSs (including 20 mg Fe) for women daily during pregnancy and 6 mo postpartum and LNSs (including 9 mg Fe) for children daily from 6 to 24 mo of age (LNS-C); 2) IFA-LNS: iron (60 mg) and folic acid (IFA) for women daily during pregnancy and every other day for 3 mo postpartum and LNS-C for children; 3) IFA-MNP: IFA for women, and MNP (including 10 mg Fe) for children daily from 6 to 24 mo; and 4) IFA-Control: IFA for women and no child supplement. Hemoglobin, serum ferritin, and soluble transferrin receptor (sTfR) were assessed in a subsample of children (n = 1121) at 18 mo to identify anemia (hemoglobin <110g/L), ID (ferritin <12 µg/L or sTfR >8.3 mg/L), and IDA. Data were analyzed with the use of mixed-effects modeling. Results Compared with the IFA-Control arm, hemoglobin was higher in the LNS-LNS and IFA-LNS arms and ferritin was higher and sTfR was lower in the LNS-LNS, IFA-LNS, and IFA-MNP arms; LNS-LNS children had reduced odds of anemia (OR: 0.46; 95% CI: 0.25, 0.84), high sTfR (OR: 0.47; 95% CI: 0.29, 0.73), and ID (OR: 0.45; 95% CI: 0.28, 0.71); and all 3 groups had lower odds of low ferritin [corrected for inflammation; OR (95% CI)-LNS-LNS: 0.29 (0.13, 0.63); IFA-LNS: 0.25 (0.11, 0.59); and IFA-MNP: 0.37 (0.18, 0.76)] and IDA [LNS-LNS: 0.35 (0.18, 0.67); IFA-LNS: 0.45 (0.24,0.85); and IFA-MNP: 0.47 (0.26, 0.87)]. Conclusions Home fortification using LNSs or MNP reduced IDA in 18-mo-old Bangladeshi children. The provision of LNSs in both pregnancy and childhood also reduced child anemia and ID. These findings are relevant to programs targeting similar populations. This trial was registered at www.clinicaltrials.gov as NCT01715038.

Unintended effects of a targeted maternal and child nutrition intervention on household expenditures, labor income, and the nutritional status of non-targeted siblings in Ghana. WORLD DEVELOPMENT 2018; 107:138-150.

Abstract
It is common for health and nutrition interventions to target specific household members and for evaluations of their effects to focus exclusively on those members. However, if a targeted intervention changes a household's utility maximization problem or influences decision-making, households might respond to the intervention in unintended ways with the potential to affect the wellbeing of non-targeted members. Using panel data from a randomized controlled nutrition trial in Ghana, we evaluate household behavioral responses to the provision of small-quantity lipid-based nutrient supplements (SQ-LNS) to mothers and their infants to prevent undernutrition. We find that targeted supplementation with SQ-LNS had a positive effect on household expenditures on food, including some nutrient-rich food groups, as well as on non-food goods and services. We also find a positive impact on labor income, particularly among fathers. We then explore intrahousehold spillover effects on the nutritional status of non-targeted young children in the household. We find evidence that the targeted provision of SQ-LNS led to higher height-for-age z-scores among non-targeted children in the LNS group compared to the non-LNS group, though only among those with relatively taller mothers, which is an indicator of a child's growth potential. These findings support existing evidence and suggest that unintended behavioral responses and spillover are a real possibility in the context of nutrition interventions targeting nutritionally-vulnerable household members. Thoughtfully considering this possibility in the design, analyses, and evaluation of targeted nutrition interventions may provide a more complete picture of overall effects.

Abstract
BACKGROUND The growing appreciation of the multi-faceted importance of optimal maternal nutrition to the health and development of the infant and young child is tempered by incompletely resolved strategies for combatting challenges. OBJECTIVE To review the importance of maternal nutrition and strategies being employed to optimize outcomes. METHODS Selected data from recent literature with special focus on rationale for and currently published results of maternal nutrition supplements, including lipid based nutrition supplements. RESULTS 1) An impelling rationale for improving the maternal and in utero environment of low resource populations has emerged to achieve improved fetal and post-natal growth and development. 2) Based partly on population increases in adult height over one-two generations, much can be achieved by reducing poverty. 3) Maternal, newborn and infant characteristics associated with low resource environments include evidence of undernutrition, manifested by underweight and impaired linear growth. 4) Apart from broad public health and educational initiatives, to date, most specific efforts to improve fetal growth and development have included maternal nutrition interventions during gestation. 5) The relatively limited but real benefits of both iron/folic acid (IFA) and multiple micronutrient (MMN) maternal supplements during gestation have now been reasonably defined. 6) Recent investigations of a maternal lipid-based primarily micronutrient supplement (LNS) have not demonstrated a consistent benefit beyond MMN alone. 7) However, effects of both MMN and LNS appear to be enhanced by commencing early in gestation. CONCLUSIONS Poor maternal nutritional status is one of a very few specific factors in the human that not only contributes to impaired fetal and early post-natal growth but for which maternal interventions have demonstrated improved in utero development, documented primarily by both improvements in low birth weights and by partial corrections of impaired birth length. A clearer definition of the benefits achievable by interventions specifically focused on correcting maternal nutrition deficits should not be limited to improvements in the quality of maternal nutrition supplements, but on the cumulative quantity and timing of interventions (also recognizing the heterogeneity between populations). Finally, in an ideal world these steps are only a prelude to improvements in the total environment in which optimal nutrition and other health determinants can be achieved.

Abstract
BACKGROUND This article summarizes a presentation given at the 2017 Dairy for Global Nutrition Conference in Boise, Idaho. OBJECTIVE To give an overview of the pattern of early growth faltering in developing countries and examine the implications of the iLiNS-DYAD randomized trial in Ghana. METHODS The pattern of growth faltering in developing countries was outlined. In Ghana, 1320 women ≤ 20 weeks of pregnancy were assigned to 20 g/d small-quantity lipid-based nutrient supplement (SQ-LNS; LNS group) or multiple micronutrients (MMNs) containing 22 and 18 vitamins and minerals, respectively, until 6 months postpartum, or iron and folic acid (IFA) until delivery, and thereafter placebo until 6 months postpartum. Infants in the LNS group were assigned to SQ-LNS from 6 to 18 months of age. RESULTS Mean anthropometric z-scores for infants in developing countries start below the World Health Organization standard at 1 month of age, and generally decline until about age of 24 months. In the Ghana trial, mean (SD) birth weight (g) was greater ( P = .044) for the LNS group (3030 [414]) than the IFA group (2945 [442]) but not the MMN group (3005 [435]). Among primiparous mothers, the LNS group had significantly greater mean birth length, weight, and head circumference than the IFA or MMN group. By 18 months of age, the mean length (95% confidence interval) for the LNS group was +0.6 (0.1-1.1) cm greater than for the IFA group and +0.6 (0.1-1.2) cm greater than for the MMN group. CONCLUSION Pre- and post-natal SQ-LNS consumption may improve fetal and infant growth in similar populations.

Ghanaian parents' perceptions of pre and postnatal nutrient supplements and their effects. MATERNAL AND CHILD NUTRITION 2018; 14:e12608.

Abstract
Small-quantity lipid-based nutrient supplements (SQ-LNS) have been studied in efficacy and effectiveness trials, but little is known about how parents perceive the products and their effects. In a randomised trial in Ghana, efficacy of SQ-LNS provided to women during pregnancy and the first 6 months postpartum and to their children from 6 to 18 months of age was assessed by comparison with iron-folic acid (IFA) capsules and multiple micronutrient (MMN) capsules provided to women. In a follow-up study conducted when the index children from the original trial were between 4 and 6 years of age, we used survey-based methods to assess retrospective and current parental perceptions of nutrient supplements generally and of SQ-LNS and their effects compared with perceptions IFA and MMN capsules. Most parents perceived that the assigned supplements (SQ-LNS, IFA, or MMN) positively impacted the mother during pregnancy (approximately 89% of both mothers and fathers) and during lactation (84% of mothers and 86% of fathers). Almost all (≥90%) of mothers and fathers perceived that the assigned supplement positively impacted the index child and expected continued positive impacts on the child's health and human capital into the future. A smaller percentage of parents perceived negative impacts of the supplements (7%-17% of mothers and 4%-12% of fathers). Perceptions of positive impacts and of negative impacts did not differ by intervention group. The results suggest that similar populations would likely be receptive to programs to deliver SQ-LNS or micronutrient capsules.

Willingness to pay for small-quantity lipid-based nutrient supplements for women and children: Evidence from Ghana and Malawi. MATERNAL & CHILD NUTRITION 2018; 14:e12518.

Abstract
Small-quantity lipid-based nutrient supplements (SQ-LNS) are designed to enrich maternal and child diets with the objective of preventing undernutrition during the first 1,000 days. Scaling up the delivery of supplements such as SQ-LNS hinges on understanding private demand and creatively leveraging policy-relevant factors that might influence demand. We used longitudinal stated willingness-to-pay (WTP) data from contingent valuation studies that were integrated into randomized controlled nutrition trials in Ghana and Malawi to estimate private valuation of SQ-LNS during pregnancy, postpartum, and early childhood. We found that average stated WTP for a day's supply of SQ-LNS was more than twice as high in Ghana than Malawi, indicating that demand for SQ-LNS (and by extension, the options for effective delivery of SQ-LNS) may be very context specific. We also examined factors associated with WTP, including intervention group, household socioeconomic status, birth outcomes, child growth, and maternal and child morbidity. In both sites, WTP was consistently negatively associated with household food insecurity, indicating that subsidization might be needed to permit food insecure households to acquire SQ-LNS if it is made available for purchase. In Ghana, WTP was higher among heads of household than among mothers, which may be related to control over household resources. Personal experience using SQ-LNS was not associated with WTP in either site.

Abstract
We examined the impact on depression at 6 months postpartum of maternal supplementation with small-quantity lipid-based nutrient supplement (SQ-LNS) compared to supplementation with iron and folic acid (IFA) or multiple micronutrients (MMN). In this partially double-blinded randomized controlled trial, pregnant women ≤20 weeks gestation (n = 1320) were recruited from antenatal clinics and randomly assigned to receive either (1) SQ-LNS during pregnancy and for 6 months postpartum, or (2) IFA during pregnancy only, or (3) MMN during pregnancy and for 6 months postpartum. Maternal depressive symptoms were measured at 6 months postpartum using the Edinburgh Postnatal Depression Scale (EPDS). Women who scored 12 or more on the EPDS were considered to show symptoms of depression. One thousand one hundred fifty-one women were included in this analysis (LNS = 382, IFA = 387 and MMN = 382). Characteristics of the three groups were similar at baseline, and there were no significant differences between women who were included in the analysis (n = 1151) and those who were not (n = 169). At 6 months postpartum, 13% of the women overall showed symptoms of depression, and this did not differ by group (LNS = 13.1%, IFA = 11.2% and MMN = 14.7%. P = 0.36). The median (25, 75 percentile) EPDS score did not differ by group (LNS 4.0 (1.0, 8.0), IFA 4.0 (1.0, 8.0), MMN 5.0 (2.0, 9.0), P transformed = 0.13). Adjustment for covariates did not alter these findings. Maternal supplementation with SQ-LNS compared to MMN or IFA did not affect postnatal depressive symptoms in this sample of Ghanaian women.

Abstract
There is little information on whether prenatal multiple micronutrient (MMN) supplements containing iodine affect women's iodine status. In the International Lipid‐based Nutrient Supplements DYAD‐Ghana trial, we aimed to assess women's urinary iodine concentration (UIC, μg/L) during pregnancy, as one of the planned secondary outcomes. Women (n = 1,320) <20 weeks of gestation were randomized to consume 60 mg iron and 400 μg folic acid per day (iron and folic acid [IFA]); 18 vitamins and minerals including 250 μg iodine per day (MMN); or 20 g/day of small‐quantity lipid‐based nutrient supplements (LNS) with the same and additional 4 vitamins and minerals as the MMN (LNS). In a subsample (n = 295), we tested differences in groups' geometric mean UICs at 36 weeks of gestation controlling for baseline UIC and compared the geometric means (approximately median UICs) with the World Health Organization (WHO) cut‐offs: median UIC <150, 150–249, and ≥500 reflecting low, adequate, and excessive iodine intakes, respectively. At baseline, overall median UIC was 137. At 36 weeks of gestation, controlling for baseline UIC, geometric mean (95% confidence interval) UICs of the MMN (161 [133, 184]) and LNS (158 [132, 185]) groups did not differ; both values were significantly greater (overall p = .004) than that of the IFA group (116 [101, 135]). The median UICs of the MMN and LNS groups were within the WHO “adequate” range, whereas that of the IFA group was below the WHO adequate range. In this setting, supplementation during pregnancy with small‐quantity LNS or MMN providing iodine at the WHO‐recommended dose, compared with IFA, increases the likelihood of adequate iodine status.

Maternal and Child Supplementation with Lipid-Based Nutrient Supplements, but Not Child Supplementation Alone, Decreases Self-Reported Household Food Insecurity in Some Settings. J Nutr 2017; 147:2309-2318. [PMID: 28978680 PMCID: PMC5697970 DOI: 10.3945/jn.117.257386] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Revised: 08/15/2017] [Accepted: 09/12/2017] [Indexed: 12/02/2022] Open
Abstract
Background: It is unknown whether self-reported measures of household food insecurity change in response to food-based nutrient supplementation.Objective: We assessed the impacts of providing lipid-based nutrient supplements (LNSs) to women during pregnancy and postpartum and/or to their children on self-reported household food insecurity in Malawi [DOSE and DYAD trial in Malawi (DYAD-M)], Ghana [DYAD trial in Ghana (DYAD-G)], and Bangladesh [Rang-Din Nutrition Study (RDNS) trial].Methods: Longitudinal household food-insecurity data were collected during 3 individually randomized trials and 1 cluster-randomized trial testing the efficacy or effectiveness of LNSs (generally 118 kcal/d). Seasonally adjusted Household Food Insecurity Access Scale (HFIAS) scores were constructed for 1127 DOSE households, 732 DYAD-M households, 1109 DYAD-G households, and 3671 RDNS households. The impact of providing LNSs to women during pregnancy and the first 6 mo postpartum and/or to their children from 6 to 18-24 mo on seasonally adjusted HFIAS scores was assessed by using negative binomial models (DOSE, DYAD-M, and DYAD-G trials) and mixed-effect negative binomial models (RDNS trial).Results: In the DOSE and DYAD-G trials, seasonally adjusted HFIAS scores were not different between the LNS and non-LNS groups. In the DYAD-M trial, the average household food-insecurity scores were 14% lower (P = 0.01) in LNS households than in non-LNS households. In the RDNS trial, compared with non-LNS households, food-insecurity scores were 17% lower (P = 0.02) during pregnancy and the first 6 mo postpartum and 15% lower (P = 0.02) at 6-24 mo postpartum in LNS households.Conclusions: The daily provision of LNSs to mothers and their children throughout much of the "first 1000 d" may improve household food security in some settings, which could be viewed as an additional benefit that may accrue in households should policy makers choose to invest in LNSs to promote child growth and development. These trials were registered at clinicaltrials.gov as NCT00945698 (DOSE) NCT01239693 (DYAD-M), NCT00970866 (DYAD-G) and NCT01715038 (RDNS).

Abstract
Background: Stunting affects ∼25% of children <5 y of age and is associated with impaired cognitive and motor development and increased morbidity and mortality. The pathogenesis of stunting is poorly understood.Objective: The purpose of this study was to identify altered metabolic pathways associated with child stunting.Design: We measured 677 serum metabolites using liquid chromatography-tandem mass spectrometry in a cross-sectional study of 400 Malawian children aged 12-59 mo, of whom 62% were stunted.Results: A low height-for-age z score (HAZ) was associated with lower serum concentrations of 1) ω-3 (n-3) and ω-6 (n-6) polyunsaturated fatty acids (PUFAs), 2) sulfated neurosteroids, which play a role in brain development, 3) carnitine, a conditionally essential nutrient with an important role in the carnitine shuttle for the metabolism of fatty acids and energy production, and 4) γ-glutamyl amino acids, which represent an altered γ-glutamyl cycle of glutathione metabolism. A low HAZ was associated with significantly higher serum concentrations of 5 biomarkers related to cigarette smoke exposure.Conclusions: This metabolomics study shows a cross-sectional association between stunting and low serum ω-3 and ω-6 long-chain PUFAs, which are essential for growth and development; low sulfated neurosteroids, which play a role in brain development; low carnitine, which is essential for β-oxidation of fatty acids; alterations in glutathione metabolism; and increased serum metabolites that are associated with secondhand tobacco smoke exposure. This trial was registered at www.controlled-trials.com as ISRCTN14597012.

Complementary Feeding Interventions Have a Small but Significant Impact on Linear and Ponderal Growth of Children in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis. J Nutr 2017; 147:2169S-2178S. [PMID: 28904113 DOI: 10.3945/jn.116.243857] [Citation(s) in RCA: 54] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2016] [Revised: 12/22/2016] [Accepted: 04/06/2017] [Indexed: 11/14/2022] Open
Abstract
Background: World Health Assembly member states have committed to ambitious global targets for reductions in stunting and wasting by 2025. Improving complementary diets of children aged 6-23 mo is a recommended approach for reducing stunting in children <5 y old. Less is known about the potential of these interventions to prevent wasting.Objective: The aim of this article was to review and synthesize the current literature for the impact of complementary feeding interventions on linear [length-for-age z score (LAZ)] and ponderal [weight-for-length z score (WLZ)] growth of children aged 6-23 mo, with the specific goal of updating intervention-outcome linkages in the Lives Saved Tool (LiST).Methods: We started our review with studies included in the previous LiST review and searched for articles published since January 2012. We identified longitudinal trials that compared children aged 6-23 mo who received 1 of 2 types of complementary feeding interventions (nutrition education or counseling alone or complementary food supplementation with or without nutrition education or counseling) with a no-intervention control. We assessed study quality and generated pooled estimates of LAZ and WLZ change, as well as length and weight gain, for each category of intervention.Results: Interventions that provided nutrition education or counseling had a small but significant impact on linear growth in food-secure populations [LAZ standardized mean difference (SMD): 0.11; 95% CI: 0.01, 0.22] but not on ponderal growth. Complementary food supplementation interventions with or without nutrition education also had a small, significant effect in food-insecure settings on both LAZ (SMD: 0.08; 95% CI: 0.04, 0.13) and WLZ (SMD: 0.05; 95% CI: 0.01, 0.08).Conclusions: Nutrition education and complementary feeding interventions both had a small but significant impact on linear growth, and complementary feeding interventions also had an impact on ponderal growth of children aged 6-23 mo in low- and middle-income countries. The updated LiST model will support nutrition program planning and evaluation efforts by allowing users to model changes in intervention coverage on both stunting and wasting.

Abstract
The main forms of childhood malnutrition occur predominantly in children <5 years of age living in low-income and middle-income countries and include stunting, wasting and kwashiorkor, of which severe wasting and kwashiorkor are commonly referred to as severe acute malnutrition. Here, we use the term 'severe malnutrition' to describe these conditions to better reflect the contributions of chronic poverty, poor living conditions with pervasive deficits in sanitation and hygiene, a high prevalence of infectious diseases and environmental insults, food insecurity, poor maternal and fetal nutritional status and suboptimal nutritional intake in infancy and early childhood. Children with severe malnutrition have an increased risk of serious illness and death, primarily from acute infectious diseases. International growth standards are used for the diagnosis of severe malnutrition and provide therapeutic end points. The early detection of severe wasting and kwashiorkor and outpatient therapy for these conditions using ready-to-use therapeutic foods form the cornerstone of modern therapy, and only a small percentage of children require inpatient care. However, the normalization of physiological and metabolic functions in children with malnutrition is challenging, and children remain at high risk of relapse and death. Further research is urgently needed to improve our understanding of the pathophysiology of severe malnutrition, especially the mechanisms causing kwashiorkor, and to develop new interventions for prevention and treatment.

Abstract
The first 1000 days of life is marked by intense metabolic activity and tissue deposition. The increased nutritional needs during this period, and the challenges to meeting them, are often not understood or appreciated. Here, we describe the nutritional needs during the first 1000 days, highlight the challenges to meeting these needs in developing countries, outline intervention strategies, and examine the consumption of small-quantity lipid-based nutrient supplements (SQ-LNS) as a promising strategy. In low-income settings, the challenge to meeting nutritional needs during the first 1000 days is worsened by overreliance on cereal-based diets of low nutrient density and high prevalence of infections and infestations. Dietary diversification is the ideal long-term solution to nutritional deficiencies, but difficulties with obtaining adequate amounts of iron, zinc, and certain vitamins may still remain. Several other interventions are available, but applying them is often fraught with challenges, including cost and contextual factors limiting efficacy. Evidence suggests that SQ-LNS supplementation may help reduce inadequate gestational weight gain and promote fetal and child growth and development in some populations. More research is needed to evaluate the effectiveness of SQ-LNS and other fortified products in different contexts and within integrated programs that address other determinants of maternal and child undernutrition.

Differing growth responses to nutritional supplements in neighboring health districts of Burkina Faso are likely due to benefits of small-quantity lipid-based nutrient supplements (LNS). PLoS One 2017; 12:e0181770. [PMID: 28771493 PMCID: PMC5542440 DOI: 10.1371/journal.pone.0181770] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2017] [Accepted: 06/28/2017] [Indexed: 12/18/2022] Open
Abstract
Background Of two community-based trials among young children in neighboring health districts of Burkina Faso, one found that small-quantity lipid-based nutrient supplements (LNS) increased child growth compared with a non-intervention control group, but zinc supplementation did not in the second study. Objectives We explored whether the disparate growth outcomes were associated with differences in intervention components, household demographic variables, and/or children’s morbidity. Methods Children in the LNS study received 20g LNS daily containing different amounts of zinc (LNS). Children in the zinc supplementation study received different zinc supplementation regimens (Z-Suppl). Children in both studies were visited weekly for morbidity surveillance. Free malaria and diarrhea treatment was provided by the field worker in the LNS study, and by a village-based community-health worker in the zinc study. Anthropometric assessments were repeated every 13–16 weeks. For the present analyses, study intervals of the two studies were matched by child age and month of enrollment. The changes in length-for-age z-score (LAZ) per interval were compared between LNS and Z-Suppl groups using mixed model ANOVA or ANCOVA. Covariates were added to the model in blocks, and adjusted differences between group means were estimated. Results Mean ages at enrollment of LNS (n = 1716) and Z-Suppl (n = 1720) were 9.4±0.4 and 10.1±2.7 months, respectively. The age-adjusted change in mean LAZ per interval declined less with LNS (-0.07±0.44) versus Z-Suppl (-0.21±0.43; p<0.0001). There was a significant group by interval interaction with the greatest difference found in 9–12 month old children (p<0.0001). Adjusting for demographic characteristics and morbidity did not reduce the observed differences by type of intervention, even though the morbidity burden was greater in the LNS group. Conclusions Greater average physical growth in children who received LNS could not be explained by known cross-trial differences in baseline characteristics or morbidity burden, implying that the observed difference in growth response was partly due to LNS.

Impact of fortified versus unfortified lipid-based supplements on morbidity and nutritional status: A randomised double-blind placebo-controlled trial in ill Gambian children. PLoS Med 2017; 14:e1002377.

Abstract
BACKGROUND Multiple micronutrients (MMN) are commonly prescribed in pediatric primary healthcare in sub-Saharan Africa to improve nutritional status and appetite without evidence for their effectiveness or international clinical guidelines. Community-wide MMN supplementation has shown limited and heterogeneous impact on growth and morbidity. Short-term ready-to-use therapeutic foods in acutely sick children in a hospital setting also had limited efficacy regarding subsequent growth. The effectiveness of MMN in improving morbidity or growth in sick children presenting for primary care has not been assessed. METHODS AND FINDINGS We undertook a double-blind randomised controlled trial of small-quantity lipid-based nutrient supplements (SQ-LNS) fortified with 23 micronutrients in children aged 6 months (mo) to 5 years (y) presenting with an illness at a rural primary healthcare centre in The Gambia. Primary outcomes were repeat clinic presentations and growth over 24 wk. Participants were randomly assigned to receive 1 of 3 interventions: (1) supplementation with micronutrient-fortified SQ-LNS for 12 wk (MMN-12), (2) supplementation with micronutrient-fortified SQ-LNS for 6 wk followed by unfortified SQ-LNS for 6 wk (MMN-6), or (3) supplementation with unfortified SQ-LNS for 12 wk (MMN-0) to be consumed in daily portions. Treatment masking used 16 letters per 6-wk block in the randomisation process. Blinded intention-to-treat analysis based on a prespecified statistical analysis plan included all participants eligible and correctly enrolled. Between December 2009 and June 2011, 1,101 children (age 6-60 mo, mean 25.5 mo) were enrolled, and 1,085 were assessed (MMN-0 = 361, MMN-6 = 362, MMN-12 = 362). MMN supplementation was associated with a small increase in height-for-age z-scores 24 wk after recruitment (effect size for MMN groups combined: 0.084 SD/24 wk, 95% CI: 0.005, 0.168; p = 0.037; equivalent to 2-5 mm depending on age). No significant difference in frequency of morbidity measured by the number of visits to the clinic within 24 wk follow-up was detected with 0.09 presentations per wk for all groups (MMN-0 versus MMN-6: adjusted incidence rate ratio [IRR] 1.03, 95% CI: 0.92, 1.16; MMN-0 versus MMN-12: 1.05, 95% CI: 0.93, 1.18). In post hoc analysis, clinic visits significantly increased by 43% over the first 3 wk of fortified versus unfortified SQ-LNS (adjusted IRR 1.43; 95% CI: 1.07, 1.92; p = 0.016), with respiratory presentations increasing by 52% with fortified SQ-LNS (adjusted IRR 1.52; 95% CI: 1.01, 2.30; p = 0.046). The number of severe adverse events during supplementation were similar between groups (MMN-0 = 20 [1 death]; MMN-6 = 21 [1 death]; MMN-12 = 20 [0 death]). No participant withdrew due to adverse effects. Study limitations included the lack of supervision of daily supplementation. CONCLUSION Prescribing micronutrient-fortified SQ-LNS to ill children presenting for primary care in rural Gambia had a very small effect on linear growth and did not reduce morbidity compared to unfortified SQ-LNS. An early increase in repeat visits indicates a need for the establishment of evidence-based guidelines and caution with systematic prescribing of MMN. Future research should be directed at understanding the mechanisms behind the lack of effect of MMN supplementation on morbidity measures and limited effect on growth.

Assessment of the effectiveness of a small quantity lipid-based nutrient supplement on reducing anaemia and stunting in refugee populations in the Horn of Africa: Secondary data analysis. PLoS One 2017; 12:e0177556.

Abstract
Stunting and micronutrient malnutrition are persistent public health problems in refugee populations. UNHCR and its partner organisations implement blanket supplementary feeding programmes using a range of special nutritional products as one approach to address these issues. The evidence base for the efficacy and effectiveness of a small quantity lipid-based nutrient supplement, Nutributter®, in reducing stunting and anaemia is limited. Secondary data analysis was used to assess the effectiveness of Nutributter® distribution on anaemia and stunting in children aged 6–23 months (programme target group) and 6–59 months (the standard age group sampled in routine nutrition surveys). Analysis was conducted using routine pre and post-intervention cross-sectional nutrition survey data collected between 2008–2011 in five refugee camps in Kenya and Djibouti. Changes in total anaemia (Haemoglobin<110g/L), anaemia categories (mild, moderate and severe), and stunting (height-for-age z-score <-2) were explored using available data on the Nutributter® programme and contextual factors. A significant reduction in the prevalence of anaemia in children aged 6–23 months and 6–59 months was seen in four of five, and in all five camps, respectively (p<0.05). Reductions ranged from 12.4 to 23.0, and 18.3 to 29.3 percentage points in each age group. Improvements were largely due to reductions in moderate and severe anaemia and occurred where the prevalence of acute malnutrition was stable or increasing. No change in stunting was observed in four of five camps. The replicability of findings across five sites strongly suggests that Nutributter® distribution was associated with a reduction in anaemia, but not stunting, among refugee children in the Horn of Africa. Benefits were not restricted to the 6–23 month target group targeted by the nutrition programme. However, even following this intervention anaemia remained a serious public health problem and additional work to define and evaluate an effective intervention package is warranted.

Abstract
Physical activity is beneficial for children’s well-being. The effect of dietary
supplementation on children’s physical activity in food-insecure areas remains little
studied. We examined the effects of a lipid-based nutrient supplement (LNS) on children’s
objectively measured physical activity in a randomised, controlled,
outcome-assessor-blinded trial. Mothers of the children received one capsule daily of
Fe-folic acid (IFA), one capsule containing eighteen micronutrients (MMN) or one 20 g
sachet of LNS (containing twenty-two MMN, protein, carbohydrates, essential fatty acids
and 494 kJ (118 kcal)) during pregnancy and for 6 months thereafter. Children in the IFA
and MMN groups received no supplementation, and these groups were collapsed into a single
control group; children in the LNS group received 20 g LNS from 6 to 18 months. We
measured physical activity with accelerometers over 1 week at 18 months. The main outcome
was mean vector magnitude counts/15 s. Of the 728 children at the beginning of child
intervention at 6 months, 570 (78 %) provided sufficient data for analysis. The mean
accelerometer counts for the 190 children in the LNS group and for the 380 children in the
control group were 303 (sd 59) and 301 (sd 56), respectively (Pfor difference=0·65). LNS, given to mothers during pregnancy and 6 months
postpartum and to their infants from 6 to 18 months of age, did not increase physical
activity among 18-month-old children.

Abstract
PURPOSE OF REVIEW Maternal and child malnutrition continues to disproportionately affect low and middle-income countries, contributing to high rates of morbidity, mortality, and suboptimal development. This article reviews evidence from recent systematic reviews and studies on the effectiveness of interventions to improve nutritional status in these especially vulnerable populations. RECENT FINDINGS Macronutrients provided to expectant mothers in the form of balanced protein energy supplements can improve fetal growth and birth outcomes, and new research suggests that lipid nutrient supplements can reduce both stunting and wasting in newborns. Maternal multiple micronutrient supplementations can also improve fetal growth, and reduce the risk of stillbirth. Nutrition education and supplementation provided to pregnant adolescents can also improve birth outcomes in this vulnerable population. New evidence is broadening our understanding of the development of gut microbiota in malnourished infants, and the possible protective role of breastmilk. SUMMARY The reviewed evidence on nutrition interventions reinforces the importance of packaging interventions delivered within critical windows throughout the life course: before conception, during pregnancy, and throughout childhood. Emerging evidence continues to refine our understanding of which populations and contexts benefit from which intervention components, which should allow for more nuanced and tailored approaches to the implementation of nutrition interventions.

Abstract
Background: Stunting in linear growth occurs mainly during the first 1000 d, from conception through 24 mo of age. Despite the recognition of this critical period, there have been few evaluations of the growth impact of interventions that cover most of this window.Objective: We evaluated home fortification approaches for preventing maternal and child undernutrition within a community-based health program. We hypothesized that small-quantity lipid-based nutrient supplements (LNSs) provided to women during pregnancy and the first 6 mo postpartum, LNSs provided to their offspring from 6 to 24 mo of age, or both would result in greater child length-for-age z score (LAZ) at 24 mo than iron and folic acid (IFA) provided to women during pregnancy and postpartum plus micronutrient powder (MNP) or no supplementation for their offspring from 6 to 24 mo.Design: We conducted a cluster-randomized effectiveness trial with 4 arms: 1) women and children both received LNSs (LNS-LNS group), 2) women received IFA and children received LNSs (IFA-LNS group), 3) women received IFA and children received MNP (IFA-MNP group), and 4) women received IFA and children received no supplements (IFA-Control group). We enrolled 4011 women at ≤20 wk of gestation within 64 clusters, each comprising the supervision area of a community health worker. Analyses were primarily performed by using ANCOVA F tests and Tukey-Kramer-corrected pairwise comparisons.Results: At 24 mo, the LNS-LNS group had significantly higher LAZ (+0.13 compared with the IFA-MNP group) and head circumference (+0.15 z score compared with the IFA-Control group); these outcomes did not differ between the other groups. Stunting prevalence (LAZ <-2) was lower in the LNS-LNS group at 18 mo than in the IFA-MNP group (OR: 0.70; 95% CI: 0.53, 0.92), but the difference diminished by 24 mo (OR: 0.81; 95% CI: 0.63, 1.04).Conclusion: Home fortification with small-quantity LNSs, but not MNP, during the first 1000 d improved child linear growth and head size in rural Bangladesh. This trial was registered at clinicaltrials.gov as NCT01715038.

Maternal Supplementation with Small-Quantity Lipid-Based Nutrient Supplements Compared with Multiple Micronutrients, but Not with Iron and Folic Acid, Reduces the Prevalence of Low Gestational Weight Gain in Semi-Urban Ghana: A Randomized Controlled Trial. J Nutr 2017; 147:697-705. [PMID: 28275100 PMCID: PMC5368579 DOI: 10.3945/jn.116.242909] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2016] [Revised: 11/29/2016] [Accepted: 02/07/2017] [Indexed: 12/15/2022] Open
Abstract
Background: It is unclear whether maternal supplementation with small-quantity lipid-based nutrient supplements (SQ-LNSs; 118 kcal/d) affects maternal weight.Objective: We compared several secondary anthropometric measures between 3 groups of women in the iLiNS (International Lipid-based Nutrient Supplements)-DYAD trial in Ghana.Methods: Women (n = 1320; <20 wk of gestation) were randomly assigned to receive 60 mg Fe + 400 μg folic acid/d (IFA), 18 vitamins and minerals/d [multiple micronutrients (MMNs)], or 20 g SQ-LNSs with 22 micronutrients/d (LNS) during pregnancy and a placebo (200 mg Ca/d), MMNs, or SQ-LNSs, respectively, for 6 mo postpartum. Weight, midupper arm circumference (MUAC), and triceps skinfold (TSF) thickness at 36 wk of gestation and 6 mo postpartum were analyzed, as were changes from estimated prepregnancy values. We assessed the adequacy of estimated gestational weight gain (GWG) by using Institute of Medicine (IOM) and International Fetal and Newborn Growth Standards for the 21st Century (INTERGROWTH-21st) guidelines.Results: The estimated prepregnancy prevalence of overweight or obesity was 38.5%. By 36 wk of gestation, women (n = 1015) had a mean ± SD weight gain of 7.4 ± 3.7 kg and changes of -1.0 ± 1.7 cm in MUAC and -2.8 ± 4.1 mm in TSF thickness. The LNS group had a lower prevalence of inadequate GWG on the basis of IOM guidelines (57.4%) than the MMN (67.2%) but not the IFA (63.1%) groups (P = 0.030), whereas the prevalence of adequate (26.9% overall) and excessive (10.4% overall) GWG did not differ by group. The percentages of normal-weight women (in kg/m2: 18.5 < body mass index < 25.0; n = 754) whose GWG was less than the third centile of the INTERGROWTH-21st standards were 23.0%, 28.7%, and 28.5% for the LNS, MMN, and IFA groups, respectively (P = 0.36). At 6 mo postpartum, the prevalence of overweight or obesity was 45.3%, and the risk of becoming overweight or obese did not differ by group.Conclusion: SQ-LNS supplementation is one potential strategy to address the high prevalence of inadequate GWG in women in settings similar to Ghana, without increasing the risk of excessive GWG. This trial was registered at clinicaltrials.gov as NCT00970866.

Social Franchising and a Nationwide Mass Media Campaign Increased the Prevalence of Adequate Complementary Feeding in Vietnam: A Cluster-Randomized Program Evaluation. J Nutr 2017; 147:670-679. [PMID: 28179488 PMCID: PMC5368587 DOI: 10.3945/jn.116.243907] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2016] [Revised: 12/13/2016] [Accepted: 01/13/2017] [Indexed: 01/25/2023] Open
Abstract
Background: Rigorous evaluations of health system-based interventions in large-scale programs to improve complementary feeding (CF) practices are limited. Alive & Thrive applied principles of social franchising within the government health system in Vietnam to improve the quality of interpersonal counseling (IPC) for infant and young child feeding combined with a national mass media (MM) campaign and community mobilization (CM).Objective: We evaluated the impact of enhanced IPC + MM + CM (intensive) compared with standard IPC + less-intensive MM and CM (nonintensive) on CF practices and anthropometric indicators.Methods: A cluster-randomized, nonblinded evaluation design with cross-sectional surveys (n = ∼500 children aged 6-23.9 mo and ∼1000 children aged 24-59.9 mo/group) implemented at baseline (2010) and endline (2014) was used. Difference-in-difference estimates (DDEs) of impact were calculated for intent-to-treat (ITT) analyses and modified per-protocol analyses (MPAs; mothers who attended the social franchising at least once: 62%).Results: Groups were similar at baseline. In ITT analyses, there were no significant differences between groups in changes in CF practices over time. In the MPAs, greater improvements in the intensive than in the nonintensive group were seen for minimum dietary diversity [DDE: 6.4 percentage points (pps); P < 0.05] and minimum acceptable diet (8.0 pps; P < 0.05). Significant stunting declines occurred in both intensive (7.1 pps) and nonintensive (5.4 pps) groups among children aged 24-59.9 mo, with no differential decline.Conclusions: When combined with MM and CM, an at-scale social franchising approach to improve IPC, delivered through the existing health care system, significantly improved CF practices, but not child growth, among mothers who used counseling services at least once. A greater impact may be achieved with strategies designed to increase service utilization. This trial was registered at clinicaltrials.gov as NCT01676623.

Abstract
Background: Nutrition during the first 1000 d is critical for brain development.Objective: We evaluated the effects on child development of home fortification with lipid-based nutrient supplements (LNSs) for mothers and/or children or micronutrient powder (MNP) for children.Design: We conducted a cluster-randomized effectiveness trial with 4 arms: 1) LNSs during pregnancy and the first 6 mo postpartum and LNSs for the offspring from 6 to 24 mo (LNS-LNS), 2) iron and folic acid (IFA) during pregnancy and the first 3 mo postpartum and LNSs for the children from 6 to 24 mo (IFA-LNS), 3) IFA (as above) and MNP for the offspring from 6 to 24 mo (IFA-MNP), and 4) IFA (as above) and no child supplement (IFA-Control). Women were enrolled at ≤20 wk of gestation; children were assessed at 12 (n = 3331), 18 (n = 3364), and 24 (n = 3379) mo.Results: Compared with the IFA-Control group, motor development scores were higher in the LNS-LNS (P = 0.016) and IFA-LNS groups (P = 0.006) at 18 mo and in the IFA-MNP group (P = 0.048) at 24 mo. Receptive language scores were higher for the LNS-LNS group (P = 0.028) at 18 mo and for all 3 groups at 24 mo (P = 0.008 for LNS-LNS, P = 0.022 for IFA-LNS, and P = 0.009 for IFA-MNP compared with IFA-Control). Expressive language scores did not differ at 18 mo (P = 0.236) but were higher in the LNS-LNS (P = 0.035) and IFA-MNP (P = 0.002) groups than in the IFA-Control group at 24 mo. Groups did not differ in personal-social scores at 18 (P = 0.233) or 24 (P = 0.146) mo or in executive function score at 24 mo (P = 0.467).Conclusion: Prenatal LNSs, postnatal LNSs, or both, or postnatal MNP had a positive effect on motor and language development in Bangladeshi children. This trial was registered at clinicaltrials.gov as NCT01715038.

Abstract
The prevalence of stunting remains high in low- and middle-income countries despite adoption of comprehensive nutrition interventions, particularly in low-income countries. In the present paper, we review current evidence on the acceptability and efficacy of small-quantity lipid-based nutrient supplements (SQ-LNS) on preventing stunting in children under 2 years, discuss the factors that affect their efficacy, highlight the implications of the current findings at pragmatic level and identify research priorities. Although the present paper is not a generic systematic review, we used a systematic approach to select relevant literature. The review showed that there is growing interest in the potential benefits of using SQ-LNS to prevent growth faltering. Acceptability studies showed that SQ-LNS are generally well accepted. However, results on the efficacy of SQ-LNS on improving linear growth or preventing growth faltering in infants and young children are still inconclusive. Factors that may affect efficacy include the duration of the trial, composition and dosage of SQ-LNS given, and baseline demographics and nutritional status of research participants. Future research should focus on controlled and long-term follow-up trials to obtain more conclusive results. In the long term, there will be need for studies to investigate how provision of SQ-LNS can be integrated with existing strategies to prevent stunting in low- and middle-income settings.

Abstract
It is unknown whether a novel small-quantity lipid-based nutrient supplement (SQ-LNS) containing alpha-linolenic (ALA) and linoleic acids impacts maternal plasma lipids and fatty acid status. We measured plasma fatty acids (wt%) and lipid concentrations at 36 wk gestation and breast milk fatty acids (wt%) at 6 months postpartum in a subsample of women enrolled in a randomized controlled trial studying the effects of SQ-LNS on birth outcomes and child growth. Women≤20 wk gestation in Ghana (n=1,320) and Malawi (n=1,391) were assigned to receive daily either: 1) iron-folic acid (pregnancy); 2) multiple micronutrients (pregnancy and lactation); or 3) SQ-LNS (pregnancy and lactation). At 36 wk, plasma ALA levels were higher in those receiving SQ-LNS. SQ-LNS increased breast milk ALA in Ghana but not Malawi. There was no effect on plasma lipids or other selected fatty acids. SQ-LNS may impact plasma and breast milk ALA levels depending on the population.

A mixed method study exploring adherence to and acceptability of small quantity lipid-based nutrient supplements (SQ-LNS) among pregnant and lactating women in Ghana and Malawi. BMC Pregnancy Childbirth 2016; 16:253. [PMID: 27577112 PMCID: PMC5004276 DOI: 10.1186/s12884-016-1039-0] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2016] [Accepted: 08/11/2016] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Supplementing pregnant and lactating mothers with small quantity lipid-based nutrient supplements (SQ-LNS) has resulted in improvements in birth outcomes in some low-income settings. In order to be effective, SQ-LNS must be consumed regularly over sustained periods. METHODS The objective was to assess and compare acceptability of and adherence to SQ-LNS consumption among pregnant and lactating women in Ghana and Malawi throughout 12 months of supplementation. We enrolled women before 20 gestation weeks into randomized trials in Ghana (n = 1320) and Malawi (n = 869). In the SQ-LNS group participants received a 20 g sachet of supplement per day during pregnancy and the first 6 months of lactation. In the control groups participants received multiple micronutrients (MMN) during pregnancy and lactation or iron and folic acid (IFA) during pregnancy and calcium during lactation. We used questionnaires to collect data on self-reported adherence to daily use of supplements and conducted in-depth interviews with women in the SQ-LNS group to examine acceptability. RESULTS The mean self-reported adherence during the supplementation period was lower in Ghana (79.9 %) than in Malawi (91.7 %) for all supplements (difference 11.8 %, P < 0.001). Over time, adherence increased in Malawi but decreased in Ghana. In both countries, adherence in the SQ-LNS group was non-inferior to that in the control groups. Participants typically reported consuming SQ-LNS as instructed but when interviewers queried about experiences, most of the women described incidents of non-adherence. A usual reason for not consuming SQ-LNS was nausea and vomiting during pregnancy. Especially in Malawi, women reported sharing SQ-LNS with families and friends. Sustained use of SQ-LNS was attributed to expected health benefits and favorable sensory attributes. Often women compared their pregnancy to previous ones, and were of the view that SQ-LNS made a positive difference. CONCLUSION Self-reported sustained adherence to consume SQ-LNS daily was high in both sites but lower in Ghana than in Malawi. In Ghana, adherence decreased over time whereas in Malawi adherence increased. Acceptability and adherence appeared interlinked, complex and context-related. Sustained consumption of SQ-LNS may require tailoring interventions by context. TRIAL REGISTRATION The Ghana trial was registered at clinicaltrials.gov as NCT00970866 , and the Malawi trial as NCT01239693 .
