Effectiveness of nutritional supplementation during the first 1000-days of life to reduce child undernutrition: A cluster randomized controlled trial in Pakistan

Specialized nutritious foods and behavior change communication interventions during the first 1000 d of life to prevent stunting: a quasi-experimental study in Afghanistan

BACKGROUND

Considerable evidence supports the effectiveness of nutritional supplementation with or without nutrition education in preventing stunting in developing countries, but evidence from Afghanistan is scarce.

OBJECTIVES

This project aimed to assess the effectiveness of specialized nutritious food (SNF), social and behavior change communication (SBCC) intervention to prevent stunting among children under 2 y during the first 1000 d of life in Badakhshan, Afghanistan.

METHODS

We used a community-based quasi-experimental pre-post study design with a control group. Pregnant and lactating women received a monthly ration of 7.5 kg of super cereal (250 g/d) during pregnancy and the first 6 mo of breastfeeding. Children aged 6-23 mo received 30 sachets of medium-quantity lipid-based nutrient supplement (50 g/sachet/d) monthly. We compared pre- and postintervention assessments of the intervention and control groups to isolate the effect of the intervention on key study outcomes at the endline by difference-in-differences (DID) estimates.

RESULTS

A total of 2928 and 3205 households were surveyed at baseline and endline. DID estimates adjusted for child, maternal, and household characteristics indicated a significant reduction in stunting (DID: -5% (95% confidence interval [CI]: -9.9, -0.2) and underweight (DID: -4.6% (95% CI: -8.6, -0.5) among children <2 y of age. However, DID estimates for wasting among children in the intervention and control groups were not significantly different (DID: -1.7 (95% CI: -5.1, 1.6). Furthermore, exposure to the SBCC messages was associated with improvements in the early initiation of breastfeeding (DID: 19.6% (95% CI: 15.6, 23.6), exclusive breastfeeding under 6 mo (DID: 11.0% (95% CI: 2.3, 19.7), minimum meal frequency (DID: 23% (95% CI: 17.7, 28.2), and minimum acceptable diet (DID: 13% (95% CI: 9.8, 16.3).

CONCLUSIONS

The provision of SNF in combination with SBCC during the first 1000 d of life was associated with reduction in stunting and underweight and improvements in infant and young child feeding practices among children under 2 y of age. This trial was registered at clinicaltrials.gov as NCT04581993.

The Effectiveness of Nutritional Interventions Implemented through Lady Health Workers on the Reduction of Stunting in Children under 5 in Pakistan: The Difference-in-Difference Analysis

In Pakistan, the 2018 National Nutrition Survey reported that 40% of children under five years old were stunted. This study assessed the effectiveness of nutritional supplementation in reducing stunting among children under five years old in two rural districts in Sindh, Pakistan. This was a mixed-method quasi-experimental study comprising intervention and control populations, with 3397 and 3277 children under five years old participating in the baseline and end-line surveys, respectively. The study areas were similar in terms of demographic and economic circumstances. In the intervention group, pregnant and lactating women (first six months post-partum) received wheat soy blend, children 6-23 months old received Wawamum (lipid-based supplement), and children 24-59 months old received micronutrient powders, all through lady health workers. This was underpinned by nutrition behaviour change communication for appropriate complementary feeding practices and hygiene promotion targeted at primary caregivers. The control group received no intervention. The impact was assessed using the difference-in-difference analysis with kernel propensity score matching to adjust the differences among the control and intervention populations. The overall DID analysis indicated that the intervention did not significantly reduce the prevalence of stunting (under 5 years) [DID = -5.1, p = 0.079]. The adjusted DID indicated a significant decrease of 13% [DID = -13.0, p = 0.001] in the number of stunted children 24-59 months of age at the endline survey. A significant reduction in underweight among children 24-59 months old was also observed (DID = -9.4%, p = 0.014). In conclusion, this evidence further establishes that nutrient uptake through an intervention for a short duration cannot effectively reduce stunting. It requires continuous nutritional supplementation for mothers during the pregnancy and an initial six months of lactation and then nutritional supplementation for children 6-59 months of age underpinned by effective behaviour change communication targeting mothers and other caregivers for improving complementary feeding practices and hygiene promotion.

Perinatal intervention strategies providing food with micronutrients to pregnant and breastfeeding women in low- and middle-income countries: A scoping review

In resource-constrained settings, pregnant and breastfeeding women and girls (PBW/G) are particularly vulnerable to undernutrition. Micronutrient-fortified balanced energy protein (BEP) supplementation may be provided to boost maternal nutritional status and improve birth and infant outcomes. We conducted a scoping review of the published literature to determine the impact of BEP and other related nutrition interventions that provided fortified food or cash along with a minimum of 3 micronutrients on maternal, birth, and infant/child outcomes in low- and middle-income countries. We conducted a PubMed search using pre-defined keywords and controlled vocabulary search terms. All titles and abstracts were reviewed for eligibility by two independent reviewers, and data were extracted according to outcome type. We identified 149 eligible research articles that reported on a total of 21 trials and/or programme evaluations which assessed the health impact of one or more products (fortified lipid-based nutrient supplement [LNS, n = 12], fortified blended flours [n = 5], milk-based beverages [n = 2], and local food/snacks [n = 3]) that provided 118-750 kcal/day and varying levels of protein and micronutrients. Only one of these programme evaluations assessed the impact of the provision of cash and fortified food. Effects on maternal outcomes such as gestational weight gain and duration of gestation were promising but inconsistent. Birth outcomes were reported in 15 studies, and the effects on birthweight and birth length were generally positive. Seven studies demonstrated sustained benefits on infant and child growth out of the 15 studies that reported at least one of these outcomes, although data were sparse. Additional research is needed to investigate issues of dose, cost-effectiveness, and incorporation into multi-component interventions.

Effect of nutrition-related infodemics and social media on maternal experience: A nationwide survey in a low/middle income country

BACKGROUND

Undernutrition is a crucial cause of morbidity and mortality among children in low- or middle-income countries (LMICs). A better understanding of maternal general healthy nutrition knowledge, as well as misbeliefs, is highly essential, especially in such settings. In the current era of infodemics, it is very strenuous for mothers to select not only the right source for maternal nutrition information but the correct information as well.

AIM

To assess maternal healthy nutritional knowledge and nutrition-related misbeliefs and misinformation in an LMIC, and to determine the sources of such information and their assessment methods.

METHODS

This cross-sectional analytical observational study enrolled 5148 randomly selected Egyptian mothers who had one or more children less than 15 years old. The data were collected through online questionnaire forms: One was for the general nutrition knowledge assessment, and the other was for the nutritional myth score. Sources of information and ways of evaluating internet sources using the Currency, Relevance, Authority, Accuracy, and Purpose test were additionally analyzed.

RESULTS

The mean general nutrition knowledge score was 29 ± 9, with a percent score of 70.8% ± 12.1% (total score: 41). The median myth score was 9 (interquartile range: 6, 12; total score: 18). The primary sources of nutrition knowledge for the enrolled mothers were social media platforms (55%). Half of the mothers managed information for currency and authority, except for considering the author's contact information. More than 60% regularly checked information for accuracy and purpose. The mothers with significant nutrition knowledge checked periodically for the author's contact information (P = 0.012). The nutrition myth score was significantly lower among mothers who periodically checked the evidence of the information (P = 0.016). Mothers dependent on their healthcare providers as the primary source of their general nutritional knowledge were less likely to hold myths by 13% (P = 0.044). However, using social media increased the likelihood of having myths among mothers by approximately 1.2 (P = 0.001).

CONCLUSION

Social media platforms were found to be the primary source of maternal nutrition information in the current era of infodemics. However, healthcare providers were the only source for decreasing the incidence of maternal myths among the surveyed mothers.

Lipid-based nutrient supplements for prevention of child undernutrition: when less may be more

BACKGROUND

Both small-quantity and medium-quantity lipid-based nutrient supplements (LNS) have been used for the prevention of child undernutrition. A meta-analysis of 14 trials of small-quantity lipid-based nutrient supplements (SQ-LNS) - no LNS showed effects on length-for-age z-score {LAZ, +0.14 [95% confidence interval (CI): 0.11, 0.16]} and weight-for-length z-score [WLZ, +0.08 (0.06, 0.10)] z-scores, as well as prevalence ratios (95% CI) for stunting [LAZ < -2, 0.88 (0.85, 0.91)] and wasting [WLZ < -2, 0.86 (0.80, 0.93)]. However, little is known about the effects of medium-quantity lipid-based nutrient supplements (MQ-LNS) on growth.

OBJECTIVES

We aimed to examine the effects of preventive MQ-LNS (∼250-499 kcal/d) provided at ∼6-23 mo of age on growth outcomes - no LNS or provision of SQ-LNS.

METHODS

We conducted a systematic review of studies of MQ-LNS for prevention, and categorized them as providing <6 mo - ≥6 mo of supplementation; for the latter category, we conducted a meta-analysis, with the main outcomes being change in WLZ and LAZ, and prevalence of wasting and stunting.

RESULTS

Three studies provided MQ-LNS for 3-5 mo (seasonal) for children 6-36 mo of age, and did not show consistent effects on growth outcomes. Eight studies provided MQ-LNS for 6-18 mo, generally starting at 6 mo of age; in the meta-analysis (max total n = 13,954), MQ-LNS increased WLZ [+0.09 (95% CI: 0.05, 0.13)] and reduced wasting [0.89 (0.81, 0.97)], but had no effect on LAZ [+0.04 (-0.02, 0.11)] or stunting [0.97 (0.92, 1.02)] - no LNS. Two studies directly compared SQ-LNS and MQ-LNS and showed no significant differences in growth outcomes.

CONCLUSIONS

The current evidence suggests that MQ-LNS offer no added benefits over SQ-LNS, although further studies directly comparing MQ-LNS with SQ-LNS would be useful. One possible explanation is incomplete consumption of the MQ-LNS ration and thus lower than desirable intake of certain nutrients.

Development and validation of the Teen Moms Child Feeding Questionnaire for Sub-Saharan Africa

BACKGROUND

In Sub-Saharan Africa, the nutritional status of children born to teenage mothers deserves critical attention. Maternal knowledge and attitudes concerning infant and young child feeding (IYCF) may predict actual practices and child nutritional status. This study created and validated the Teen Moms Child Feeding Questionnaire for Sub-Saharan Africa.

METHODS

A literature search on IYCF knowledge and attitude gaps in teenage mothers generated scale items. Ten nutrition experts and six teenage mothers assessed content validity and comprehensibility, respectively. Construct validation was conducted by item response theory (IRT) and confirmatory factor analysis (CFA), in 150 teenage mothers in rural communities of Abuja, Nigeria. Model fit parameters were estimated by standardized chi-square tests. Internal consistency reliability was determined by marginal reliability and Cronbach's alpha. In a sub-sample of 40 women who completed the questionnaire two weeks later, test-retest reliability was assessed via intraclass correlations.

RESULTS

The IRT analysis retained 23 knowledge items on infant food type, breastfeeding and complementary feeding, with acceptable discrimination and difficulty. CFA produced a six-factor solution (exclusive breastfeeding, breast milk expression, meal frequency, responsive feeding, dietary diversity, and barriers) with 17 attitude items. Confirmatory fit and Tucker Lewis indices > 0.9; Root Mean Square Errors of Approximation and Standardized Root Mean Square Residuals < 0.08, showed good model fit. Overall Cronbach's alpha of the attitude scale (0.843), subscales (≥ 0.6) and high intraclass correlation coefficients (> 0.75) indicated reliability.

CONCLUSION

The Teen Moms Child Feeding Questionnaire for Sub-Saharan Africa is a valid assessment tool for IYCF knowledge and attitudes of teenage mothers.

Drivers of Nutritional Change in Pakistan: A Decomposition Analysis

The global reduction in child undernutrition highlights the international and national commitment to prioritizing future generations' health. This study aims to find out the previous trends in nutrition and the key drivers of these changes in different regions of Pakistan. For empirical investigation, we employed a regression-based decomposition model by using two distinct rounds of demographic and health surveys: 2012-13 and 2017-18. Results showed children with stunted growth reduced substantially in Balochistan, while Punjab exhibited the highest progress for underweight children. Regression estimates showed that maternal nutritional status and household wealth were more pronounced in reducing all measures of child malnutrition. Some determinants, including mother age at marriage and prenatal visits to the hospital, are significant only for long-term nutritional status-stunting, while mother education contributed to reducing wasted and underweight children. The rest of the factors, like father education and household environment, appear to play a humble role in explaining nutritional improvements. From disaggregated analysis based on different regions, we found that modeled factors used in this study explained changes disproportionately. Thus, it is recommended to use multidimensional nutrition policies incorporating a broader range of sectors, and region-specific programs should be designed for more effective outcomes.
