Preconception nutrition intervention improved birth length and reduced stunting and wasting in newborns in South Asia: The Women First Randomized Controlled Trial

Influence of Socioeconomic Factors and Nutritional Advice on Diet Quality in Women of Reproductive Age: A FIGO-DQS Assessment

BACKGROUND/OBJECTIVES

Nutritional knowledge, attitudes, and practice are important ways of assuring a healthy pregnancy start, which can be shaped during the pre-pregnancy period by the intervention of healthcare providers. In this cross-sectional study, the main objective was to explore contextual determinants of diet quality in women of fertile age, including socioeconomic factors and sources of information.

METHODS

Data on socioeconomic background, sources of nutritional advice, and determinants of food choices were collected through an anonymous web-based questionnaire completed by 465 women. Diet quality was assessed with the International Federation of Gynaecology and Obstetrics diet quality score (FIGO-DQS).

RESULTS

Better food choices (OR = 1.73; 95% CI: 1.16-2.51), higher knowledge level (OR = 1.66; 95% CI: 1.119-2.466), and healthcare advice (OR = 1.70, 95% CI: 1.119-2.466) increased the chances of having a better diet. Both healthcare providers (β = 0.503, p = 0.018) and determinants of food choices (β = 0.520, p = 0.011) had a significant influence on the FIGO score, although the advice provided by the healthcare professionals did not yield a significant influence on the determinants of food choices (β = 0.310, p = 0.125); Conclusions: Knowledge had a mediator effect on the impact of healthcare guidance on nutrition practices, but it does not fully explain the adherence to healthy lifestyle choices.

Implementation of preconception care for preventing adverse pregnancy outcomes in rural and tribal areas of Nashik District, India

Introduction

The World Health Organization has suggested preconception care to improve pregnancy outcomes. Hence, the study aimed to compare the effect of preconception care on pregnancy outcomes, particularly prematurity and low birth weight.

Methods

We carried out interventions in one tribal and one non-tribal block. For comparison, one adjacent tribal block and one non-tribal block were included in Nashik district, India. The total study period was from April 2018 to July 2021. All reproductive age group women desiring pregnancy within one year in selected four blocks participated in the study. The services included clinical examination, laboratory investigations, treatment, six-monthly deworming, anemia management, folic acid supplementation, family planning services, and behavioral change communication using different media. The existing healthcare workers provided services to the women until they became pregnant or until the end of the follow-up period (27 months). We monitored pregnancy outcomes, including abortion, stillbirth, and live birth; among live births, low birth weight, preterm birth, congenital physical anomaly, and neonatal death.

Results

The study enrolled 7,875 women, and 3,601 had outcomes. The proportion of preterm births in the intervention and comparison block was 11.18 % and 14.99 %, respectively (p = 0.001), and the proportion of low-birth-weight babies was 9.23 % and 11.25 %, respectively (p = 0.01). The adjusted prevalence ratio showed that the risk of preterm births in the absence of intervention was 1.3 (CI: 1.1-1.6). Preterm birth was a mediator between preconception care and low birth weight.

Conclusion

Reduction in proportion of low birth weight and preterm babies can be achieved through preconception care using minimal additional resources.

Effect of preconception multiple micronutrients vs. iron-folic acid supplementation on maternal and birth outcomes among women from developing countries: a systematic review and meta-analysis

Background

Maternal malnutrition affects the somatic growth of the fetus and subsequent adverse events during infancy and childhood period. Though trials have been conducted on multiple micronutrient (MMN) supplements initiated during the preconception period, there is no collated evidence on this.

Materials and methods

We performed a systematic review of published trials with the application of Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The searches were conducted until 30 September 2023. Meta-analysis was performed using Review Manager 5 software. The primary objective was to compare the effect of preconception MMN vs. iron-folic acid (IFA) supplementation on newborn anthropometric parameters at birth.

Results

Of the 11,832 total citations retrieved, 12 studies with data from 11,391 participants [Intervention = 5,767; Control = 5,624] were included. For the primary outcome, there was no significant difference in the birth weight [MD, 35.61 (95% CI, -7.83 to 79.06), p = 0.11], birth length [MD, 0.19 (95% CI, -0.03 to 0.42), p = 0.09], and head circumference [MD, -0.25 (95% CI, -0.64 to -0.14), p = 0.22] between the MMN and control groups. For all the secondary outcomes [except for small for gestational age (SGA) and low birth weight (LBW)], the difference between the MMN and control groups was not significant. The GRADE evidence generated for all the outcomes varied from "very low to moderate certainty."

Conclusion

A "very low certainty" of evidence suggests that MMN supplementation may not be better than routine IFA supplementation in improving newborn anthropometric parameters (weight, length, and head circumference). The adverse events resulting from the supplementation were not significant. We need better quality uniformly designed RCTs before any firm recommendation can be made.Systematic review registration: identifier (CRD42019144878: https://www.crd.york.ac.uk/prospero/#searchadvanced).

Preconception Micronutrient Supplementation Affects Maternal BMI and Body Composition Postpartum: A Randomized Controlled Trial in Vietnam

BACKGROUND

Although there is growing evidence on the role of preconception nutrition for birth outcomes, limited evidence exists for its effects on maternal health.

OBJECTIVES

This study evaluates the impact of preconception micronutrient supplementation on maternal BMI (kg/m2) and body composition at 6 to 7 y postpartum (PP).

METHODS

We followed females who participated in a randomized controlled trial of preconception supplementation in Vietnam and delivered live offspring (n = 1599). Females received weekly supplements containing either 2800 μg folic acid (FA) only, 60 mg iron and 2800 μg FA (IFA), or multiple micronutrients (MMs) (15 micronutrients including IFA) from baseline until conception followed by daily prenatal IFA supplements until delivery. Height, weight, mid-upper arm circumference, triceps skinfold, and waist-hip circumference were measured at recruitment and at 1, 2, and 6 to 7 y PP. Body fat was assessed using bioelectric impedance at 6 to 7 y PP (n = 867). Group comparisons were made using analysis of variance or chi-square tests and general linear models for adjusted models.

RESULTS

At 6 to 7 y PP, we found significant differences (P < 0.05) by treatment group for mean percent fat (MM: 29.2%; IFA: 27.6%; FA: 27.8%), absolute fat mass (MM: 15.1 kg; IFA: 14.0 kg; FA: 14.3 kg), and prevalence of underweight based on BMI < 18.5 (MM: 5.8%; IFA: 10.3%; FA: 14.3%). Mean BMI and triceps skinfold thickness were higher in the MM group, but these differences were not statistically significant; the differences in absolute fat mass were also attenuated after controlling for body weight. No differences were observed for fat-free mass, prevalence of overweight (BMI >23), or other anthropometric measurements.

CONCLUSIONS

Preconception MM supplementation was associated with lower prevalence of underweight and higher percent fat when compared with IFA and/or FA only. Preconception micronutrient interventions may have long-term effects on maternal health and merit further examination. This trial was registered at clinicaltrials.gov as NCT01665378.

Exploring the relationships between pre-pregnancy BMI, gestational weight gain, and nutritional intake: a real-world investigation in Shandong, China

This study investigated the associations between gestational weight gain (GWG), pre-pregnancy body mass index (BMI), and prenatal diet quality in pregnant women from Shandong, China. We analyzed a sample of 532 early-stage pregnant women registered at an outpatient clinic. Diet quality was evaluated using the Chinese Healthy Dietary Index for Pregnancy (CHDI-P), encompassing three dimensions: diversity, adequacy, and limitation, with an overall score out of 100. Dietary intake was documented via 24-h dietary recalls spanning three consecutive days and subsequently translated to a CHDI-P score. At the time of enrollment, BMI was measured on-site and classified as underweight (<18.5), normal weight (18.5-24.9), overweight (25.0-29.9), and obese (≥30.0). Pregnant women were also categorized into inadequate, adequate, and excessive weight gain groups based on their GWG. We employed a Tukey-adjusted generalized linear model to compare the CHDI-P scores between the pre-pregnancy BMI groups and GWG groups. The results revealed that the underweight group had significantly higher total scores and limitation total scores on the CHDI-P (p < 0.001). Conversely, the overweight and obese groups were more susceptible to suboptimal dietary quality. Notably, the inadequate weight gain group displayed significantly elevated food adequacy scores compared to the other two groups (p < 0.05). This indicates that greater GWGs do not necessarily align with principles of adequate nutrition.

Stunting in the first year of life: Pathway analysis of a birth cohort

Malnutrition among infants aged below 6 months has been largely overlooked creating gaps in our understanding of factors underlying stunting in early infancy. Recent evidence suggests that pre-natal and early childhood factors may contribute more to driving childhood stunting than previously appreciated. The study was set up to examine pathways including parental and household characteristics, birth size and gestation, and illness in infancy with stunting at birth and months 3, 6 and 12 using an a priori hypothesized framework. It was a secondary analysis of a birth cohort of 1017 infants recruited from four health facilities in Burkina Faso and followed up for one year. Structural equation models (SEM) were generated to explore pathways to stunting at birth and months 3, 6 and 12. The prevalence of being stunted at birth and months 3, 6 and 12 was 7.4%, 23%, 20% and 18% respectively. The fractions of month 12 stunting attributable to being stunted at birth, months 3 and 6 were 11% (95%CI 5.0‒16%), 32% (95%CI 22‒41%) and 40% (95%CI 31‒49%) respectively. In the structural equation model, male sex and maternal characteristics had direct effects on stunting at birth and at 3 months, but not subsequently. Premature birth, twin birth and being stunted at a previous time point were directly associated with stunting at months 3, 6 and 12. Both maternal and paternal characteristics were directly associated with preterm birth. Non-exclusive breastfeeding had borderline positive direct effect on stunting at month 6 but not at month 12. The direct and indirect pathways identified in this study highlight the complex interlinks between child, maternal, paternal and household characteristics. Interventions tackling preterm birth, in utero growth, exclusive breastfeeding and maternal wellbeing may reduce stunting in the first year of life.

Associations between socio-demographic characteristics of pregnant women and birth outcome: The Nutritional status of Expectant Mothers and their newborn Infants study

BACKGROUND

Low socio-economic status is associated with poor birth outcomes, however, few studies on this topic have been conducted in South Africa. We determined associations between socio-demographic variables of pregnant women and birth outcome in their offspring.

METHODS

This study was nested in a prospective cohort study conducted at an antenatal clinic at a regional hospital in Bloemfontein, South Africa. Questionnaires on socio-demographic information were completed on 682 pregnant women in a structured interview. Post-delivery, 331 participants provided the Road to Health Booklets for 347 infants, in which birth data were recorded. Associations between socio-demographic variables and birth outcome (defined as premature delivery or low length-for-age or low weight-for-length at birth) were investigated. Logistic regression with backward selection (p < 0.05) was used to select independent factors that were significantly associated with birth outcome. Variables with a p-value of <0.15 on bivariate analysis were considered for inclusion in the model.

RESULTS

Poor birth outcome was observed in 36.3% (116/320) of women. The odds of experiencing poor birth outcome were lower for women who owned a stove versus those who did not (OR 0.11, 95% CI: 0.02-0.67), and higher for women with grade 8-10 (OR 5.84, 95% CI: 1.90-17.91) or grade 10-12 (OR 4.33, 95% CI: 1.50-12.49) as their highest level of education versus tertiary education. The odds of experiencing poor birth outcomes were also higher for those employed part-time (OR 2.55, 95% CI: 1.10-5.93) versus full-time and/or self-employed.

CONCLUSION

Our findings confirm that the presence of basic amenities such as a stove, better education and employment improve the chances of better birth outcomes. Early screening of pregnant women for the identification of socio-demographic risk factors that may impact on birth outcome is recommended.

The why, what and how of preconception care: an exploratory descriptive qualitative study in Karnataka, India

BACKGROUND

Women's health and nutrition are key to their reproductive health and are important for optimising pregnancy outcomes. Formation of most foetal organs starts soon after conception and much before the woman has her first antenatal visit. The provision of biomedical, behavioural and social interventions to couples to address health, nutrition, behaviour issues and individual environmental risk factors that could contribute to improved maternal and child health outcomes before conception is crucial. Most rural women in India, do not seek pregnancy care before the second trimester because of socio-cultural factors. Therefore, intervening in the preconception period is important. The objective of the study was to explore the challenges and opportunities of implementing preconception care interventions.

METHODS

Individual, in-depth, semi-structured interviews (n = 25) were conducted with primary stakeholders (newly married women, newly married men, and family members) in Shorapur taluk of Yadgir district and Devadurga taluk of Raichur district. Thirty-one interviews were conducted with taluk, district, state officials and academicians. This descriptive qualitative study conducted four focus group discussions with front-line health workers. The in-depth interviews (IDIs) and Focus-group discussions (FGDs) used separate pre-tested semi-structured interview/discussion guides. Data analysis was carried out using NVivo software using a phenomenological approach with both inductive and deductive analysis.

RESULTS

A strong influence of social and cultural norms shapes healthcare-seeking behaviour at the community level. Poor dietary diversity, lack of awareness, poor literacy levels, work pressure for women, lack of decision-making power and empowerment among women, pressure to conceive early, and gender norms are the roadblocks to successful preconception care programs in the rural Karnataka setting. The stakeholders expressed the need for interventions during the preconception period. The government functionaries recommended several interventions which could be potentially integrated into the existing Reproductive Maternal, Neonatal, Child and Adolescent Health (RMNCH + A) strategy to improve the health and nutrition of women before they conceive.

CONCLUSION

The study highlights the need for structured interventions during the preconception period to improve maternal health and pregnancy outcomes. The recommendations provided by government functionaries are indicative of the feasibility of integrating interventions in the RMNCH + A strategy.

Pre-pregnancy Diet to Maternal and Child Health Outcome: A Scoping Review of Current Evidence

OBJECTIVES

Pre-pregnancy diet has an important role in preparing for healthy generation. However, evidence on this issue has been scarce. A scoping review synthesising current evidence will support the demand to map 'what has been researched' on pre-pregnancy diet and maternal and child health.

METHODS

Systematic search was performed using PICOS (Population, Intervention, Comparison, Outcomes, and Study design) framework in electronic databases. Articles were screened for eligibility, summarized, and the quality was assessed using the National Institute of Health assessment tool. The review structure complies with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guide.

RESULTS

Forty-two articles were included after full-text screening. Twenty-five studies were in high-income countries (HICs), six in each upper-middle income, five in lower-middle income countries (LMICs), and one in low-income countries (LIC). Based on the regions: North America (n=16), Europe (n=5), South America (n=4), Australia (n=4), Asia (n=5), Middle East (n=2), and sub-Saharan Africa (n=1). The two-most observed diet-related exposures were dietary pattern (n=17) and dietary quality (n=12). The most assessed outcome was gestational diabetes mellitus (n=28) and fetal and newborn anthropometry (n=7). The average quality score±standard deviation was 70±18%.

CONCLUSIONS

Research related to pre-pregnancy diet is still concentrated in HICs. The context of diet may vary; therefore, future research is encouraged in LMICs and LICs context, and Mediterranean, South-East Asia, Pacific, and African regions. Some maternal and child nutrition-related morbidity, such as anemia and micronutrient deficiencies, have not been discussed. Research on these aspects will benefit to fill in the gaps related to pre-pregnancy diet and maternal and child health.

Birth length is the strongest predictor of linear growth status and stunting in the first 2 years of life after a preconception maternal nutrition intervention: the children of the Women First trial

BACKGROUND

The multicountry Women First trial demonstrated that nutritional supplementation initiated prior to conception (arm 1) or early pregnancy (arm 2) and continued until delivery resulted in significantly greater length at birth and 6 mo compared with infants in the control arm (arm 3).

OBJECTIVES

We evaluated intervention effects on infants' longitudinal growth trajectory from birth through 24 mo and identified predictors of length status and stunting at 24 mo.

METHODS

Infants' anthropometry was obtained at 6, 12, 18, and 24 mo after the Women First trial (registered at clinicaltrials.gov as NCT01883193), which was conducted in low-resource settings: Democratic Republic of Congo, Guatemala, India, and Pakistan. Longitudinal models evaluated intervention effects on infants' growth trajectory from birth to 24 mo, with additional modeling used to identify adjusted predictors for growth trajectories and outcomes at 24 mo.

RESULTS

Data for 2337 (95% of original live births) infants were evaluated. At 24 mo, stunting rates were 62.8%, 64.8%, and 66.3% for arms 1, 2, and 3, respectively (NS). For the length-for-age z-score (LAZ) trajectory, treatment arm was a significant predictor, with adjusted mean differences of 0.19 SD (95% CI: 0.08, 0.30; P < 0.001) and 0.17 SD (95% CI: 0.07, 0.27; P < 0.001) for arms 1 and 2, respectively. The strongest predictors of LAZ at 24 mo were birth LAZ <-2 and <-1 to ≥-2, with adjusted mean differences of -0.76 SD (95% CI: -0.93, -0.58; P < 0.001) and -0.47 SD (95% CI: -0.56, -0.38; P < 0.001), respectively. For infants with ultrasound-determined gestational age (n = 1329), the strongest predictors of stunting were birth LAZ <-2 and <-1 to ≥- 2: adjusted relative risk of 1.62 (95% CI: 1.39, 1.88; P < 0.001) and 1.46 (95% CI: 1.31, 1.62; P < 0.001), respectively.

CONCLUSIONS

Substantial improvements in postnatal growth are likely to depend on improved intrauterine growth, especially during early pregnancy.

Socio-economic and socio-demographic determinants of diet diversity among rural pregnant women from Pune, India

Background

Diet diversity signifies the nutrient adequacy of an individual and thus has gained widespread significance in recent times. In developing countries achieving maximum diet diversity, especially among pregnant women from rural areas is challenging although of great importance. However, to do so understanding the primary factors associated with diet diversity is important. This paper, therefore, assessed the socio-demographic and socio-economic determinants of diet diversity among rural pregnant women in India.

Methods

The study consisted of a community-based prospective cohort of n = 204 pregnant women attending primary healthcare centers (PHC) across 14 villages in Mulshi Taluka, Pune, Maharashtra, India. The data was collected using a structured questionnaire through a one-to-one interview method.

Results

The prevalence of low, medium and high diet diversity was 56.4%, 33.3%, and 10.3% respectively. Minimum diversity in the diet was achieved among 73.5% of pregnant women. The mean diet diversity score (DDS) was 3.6 ± 1.3 with starchy staples being (100%) of commonly consumed foods. Young (< 20 years) women (OR = 5.2; CI:1.9- 13.8), housewives (OR = 3; CI:1.4–6.7), husbands working as skilled laborers (OR = 2.5; CI:1.2–5.5) were at significant risk of having low diet diversity scores. Whereas, those living in a joint family (OR = 0.3; CI:0.1–0.6), not owning a house (OR = 0.5; CI:0.2–0.9), and having a poor income (OR = 1.9; CI: 0.9- 3.7) were less likely to have low diet diversity.

Conclusion

Socio-economic and demographic factors (maternal age, mother's occupation, and husband's occupation) influenced the diet diversity among pregnant women. Monotonous diets are commonly seen in developing countries, especially in rural areas which can be a risk factor for poor nutrient adequacy and health of pregnant women. Policies and programs about these determinants of diet diversity should be enacted to replace the poor quality diets to ensure improved diet diversity and nutrient adequacy.

The importance of nutrition in pregnancy and lactation: lifelong consequences

Most women in the United States do not meet the recommendations for healthful nutrition and weight before and during pregnancy. Women and providers often ask what a healthy diet for a pregnant woman should look like. The message should be “eat better, not more.” This can be achieved by basing diet on a variety of nutrient-dense, whole foods, including fruits, vegetables, legumes, whole grains, healthy fats with omega-3 fatty acids that include nuts and seeds, and fish, in place of poorer quality highly processed foods. Such a diet embodies nutritional density and is less likely to be accompanied by excessive energy intake than the standard American diet consisting of increased intakes of processed foods, fatty red meat, and sweetened foods and beverages. Women who report “prudent” or “health-conscious” eating patterns before and/or during pregnancy may have fewer pregnancy complications and adverse child health outcomes. Comprehensive nutritional supplementation (multiple micronutrients plus balanced protein energy) among women with inadequate nutrition has been associated with improved birth outcomes, including decreased rates of low birthweight. A diet that severely restricts any macronutrient class should be avoided, specifically the ketogenic diet that lacks carbohydrates, the Paleo diet because of dairy restriction, and any diet characterized by excess saturated fats. User-friendly tools to facilitate a quick evaluation of dietary patterns with clear guidance on how to address dietary inadequacies and embedded support from trained healthcare providers are urgently needed.

Recent evidence has shown that although excessive gestational weight gain predicts adverse perinatal outcomes among women with normal weight, the degree of prepregnancy obesity predicts adverse perinatal outcomes to a greater degree than gestational weight gain among women with obesity. Furthermore, low body mass index and insufficient gestational weight gain are associated with poor perinatal outcomes. Observational data have shown that first-trimester gain is the strongest predictor of adverse outcomes. Interventions beginning in early pregnancy or preconception are needed to prevent downstream complications for mothers and their children. For neonates, human milk provides personalized nutrition and is associated with short- and long-term health benefits for infants and mothers. Eating a healthy diet is a way for lactating mothers to support optimal health for themselves and their infants.

Scoping Review of Intervention Strategies for Improving Coverage and Uptake of Maternal Nutrition Services in Southeast Asia

Maternal undernutrition can lead to protein-energy malnutrition, micronutrient deficiencies, or anemia during pregnancy or after birth. It remains a major problem, despite evidence-based maternal-nutrition interventions happening on ground. We conducted a scoping review to understand different strategies and delivery mechanisms to improve maternal nutrition, as well as how interventions have improved coverage and uptake of services. An electronic search was conducted in PubMed and Google Scholar for published studies reporting on the effectiveness of maternal-nutrition interventions in terms of access or coverage, health outcomes, compliance, and barriers to intervention utilization. The search was limited to studies published within ten years before the initial search date, 8 November 2019; later, it was updated to 17 February 2021. Of 31 studies identified following screening and data extraction, 22 studies were included for narrative synthesis. Twelve studies were reported from India and eleven from Bangladesh, three from Nepal, two from both Pakistan and Thailand (Myanmar), and one from Indonesia. Nutrition education and counselling, home visits, directly observed supplement intake, community mobilization, food, and conditional cash transfer by community health workers were found to be effective. There is a need to incorporate diverse strategies, including various health education approaches, supplementation, as well as strengthening of community participation and the response of the health system in order to achieve impactful maternal nutrition programs.

Stunting Prevention with Education and Nutrition in Pregnant Women: A Review of Literature

Background : Stunting is a major nutritional problem in children under five years old which has an impact on slowing growth by reducing the number and development of body cells, including brain cells and other organs. Pregnant women are one of the groups who are vulnerable to nutritional problems, related to the process of growth and development of the fetus in the womb. The role of education and nutrition is important during pregnancy because it has implications for the health of mothers and children in later life. The aimed of this review was to identify research about effect stunting prevention and education and nutrition to pregnant women. Methods : A database review undertaken using Pubmed, CHINAHL and Google Scholar from 2011-2021 to collect focused study on education and nutrition research on pregnant women to prevent stunting. A total of 1788 articles were identified. These were scaned and 18 articles were retrieved with 13 articles shortlisted for to in depth review. Results : Education with using audiovisual media, moringa leaf ice cream and early nutrition has proved effective in increasing pregnant women knowledge regarding stunting prevention. Providing nutritional supplements/nutrients for moringa oliefera, folic acid and iron, specific nutrition, LNS, PM2A PROCOMIDA, nutrition before pregnancy, supplements antenatal iron and folic acid, prenatal micronutrients have an effect on reducing children stunting. Conclusion: Audio visual education can convery health knowledge because easily to facilitate the reception of health message for pregnant women. Continuous education and monitoring of the of pregnant women diet every month during pregnancy classes at the posyandu are needed to prevent stunting in children.  

Preconception micronutrient supplementation positively affects child intellectual functioning at 6 y of age: A randomized controlled trial in Vietnam

BACKGROUND

Although there is growing evidence on the role of preconception nutrition for birth outcomes, very few studies have evaluated the long-term effects of nutrition interventions during the preconception period on offspring cognitive outcomes.

OBJECTIVE

We evaluate the impact of preconception weekly multiple micronutrients (MMs) or iron and folic acid (IFA) supplementation compared with folic acid (FA) alone on offspring intellectual functioning at age 6-7 y.

METHODS

We followed 1599 offspring born to women who participated in a double-blinded randomized controlled trial of preconception supplementation in Vietnam. Women received weekly supplements containing either 2800 μg FA only, 60 mg iron and 2800 μg FA, or MMs (15 micronutrients including IFA) from baseline until conception, followed by daily prenatal IFA supplements until delivery. We used the Wechsler Intelligence Scale for Children to measure full-scale IQ (FSIQ) and 4 related domains of intellectual functioning [Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), Working Memory Index (WMI), and Processing Speed Index (PSI) scores] at 6-7 y. Group comparisons were done using ANOVA tests for all children and the subgroup born to women who consumed the supplements ≥26 wk before conception (per-protocol analyses).

RESULTS

The final sample with data at 6-7 y (n = 1321) was similar for baseline maternal and offspring birth characteristics and age at follow-up by treatment group. Compared with the offspring in the FA group, those in the MM group had higher FSIQ (β = 1.7; 95% CI: 0.1, 3.3), WMI (β = 1.7; 95% CI: 0.2, 3.2), and PSI (β = 2.5; 95% CI: 0.9, 4.1). Similar findings were observed in the per-protocol analyses. There were no significant differences by treatment group for VCI and PRI.

CONCLUSIONS

Preconception supplementation with MMs improved certain domains of intellectual functioning at age 6-7 y compared with FA. These findings suggest the potential for preconception micronutrient interventions to have long-term benefits for offspring cognition.

The effect of nutrition and reproductive health education of pregnant women in Indonesia using quasi experimental study

BACKGROUND

Almost one-third of children under 5 years old in Indonesia suffer from stunting. Stunting can be prevented optimally during pregnancy as the initial phase of the first 1000 days of life. This study aims to determine the effect of nutrition and reproductive health education of pregnant women in Bogor Regency, Indonesia.

METHODS

A quasi-experimental study was conducted among 194 pregnant women from August to November 2019. The pregnant women were randomly selected from four different villages in Bogor Regency. The intervention group (n = 97) received 2 h of nutrition and reproductive health education in small groups (four or five mothers per group) every 2 weeks for 3 consecutive months. This interactive education was given by facilitators using techniques such as lectures, role-playing, simulation, and games. The control group (n = 97) received regular health care services. A structured questionnaire was applied to collect data consisting of maternal characteristics, nutritional and reproductive health knowledge, attitudes, and practices in the intervention and control groups. Data were analysed using t-test and chi-square analysis.

RESULTS

Pregnant women in the intervention group indicated a significant increase in knowledge, attitudes, and practices regarding nutrition and reproductive health after receiving education. The pre-test and post-test mean scores in the intervention group were 55.1 and 83.1 for overall knowledge, 40.2 and 49.0 for attitudes, and 36.2 and 40.2 for practices, respectively. In the control group, there was no significant difference between the pre-test and post-test mean scores for these three variables. There was a significant difference (P < 0.001) in the post-test mean between the intervention group and the control group, but the difference was not significant (P > 0.05) in the pre-test.

CONCLUSION

Providing nutrition and reproductive health education through small groups with interactive methods improves the knowledge, attitudes, and practices of pregnant women. This intervention has the potential to be replicated and developed for large-scale implementation by optimising collaboration between government, non-governmental organizations, and maternal and child health service providers.

Childbearing Age Women Characteristics in Latin America. Building Evidence Bases for Early Prevention. Results from the ELANS Study

Latin American (LA) women have been exposed to demographic and epidemiologic changes that have transformed their lifestyle, with increasing sedentary and unhealthy eating behaviors. We aimed to identify characteristics of LA women to inform public policies that would benefit these women and their future children. The Latin American Study of Nutrition and Health (ELANS) is a multicenter cross-sectional study of representative samples in eight Latin American countries (n = 9218) with a standardized protocol to investigate dietary intake, anthropometric variables, physical activity, and socioeconomic characteristics. Here we included the subsample of all 3254 women of childbearing age (15 to <45 years). The majority of ELANS women had a low socioeconomic status (53.5%), had a basic education level (56.4%), had a mostly sedentary lifestyle (61.1%), and were overweight or obese (58.7%). According to the logistic multiple regression model, living in Peru and Ecuador predicts twice the risk of being obese, and an increased neck circumference is associated with a 12-fold increased obesity risk. An increased obesity risk was also predicted by age <19 years (Relative Risk (RR) 19.8) and adequate consumption of vitamin D (RR 2.12) and iron (RR 1.3). In conclusion, the identification of these risk predictors of obesity among Latin American women may facilitate targeted prevention strategies focusing on high-risk groups to promote the long-term health of women and their children.

Effect of a Nutrient-Rich, Food-Based Supplement Given to Rural Vietnamese Mothers Prior to or during Pregnancy on the Trajectories of Nutrient Biomarkers

Nutrient interventions initiated after conception tend to have modest effects on maternal nutritional status and pregnancy outcomes. Thus, we compared the association between micronutrient intakes and the trajectories of their biomarkers before and during pregnancy. Data from a randomized trial of the effect of a nutrient-rich, food-based supplement given to 317 Vietnamese women prior to or during pregnancy on birth outcomes were used to assess nutrient intakes with biomarker trajectories of zinc, iron, folate, cobalamin, and vitamin A using linear mixed regression models. The circulating plasma or serum trajectories of all five micronutrients were associated to their baseline levels (p < 0.0001). Plasma zinc trajectories were also related to farm work (p = 0.024). Cobalamin and vitamin A trajectories were associated with gestational weight gain (p = 0.003 and p = -0.037, respectively). In this population of rural Vietnamese women, nutrient intakes during pregnancy did not affect biomarker trajectories. The primary determinant of each nutrient biomarker trajectory was its respective baseline level prior to conception.
