Abstract
BACKGROUND Large-scale social and behavioral change communication (SBCC) approaches can be beneficial to achieve improvements in knowledge, attitudes, and practices (KAP). Addressing Stunting in Tanzania Early (ASTUTE) included a significant SBCC component and targeted precursors to stunting including KAP related to maternal and child health, antenatal care, WASH, childhood development, and male involvement. METHODS Baseline, midline, and endline surveys were conducted for a total of 14,996 female caregivers and 6726 male heads of household in the Lake Zone region of Tanzania. Regression analyses were used to estimate differences in KAP from baseline to midline and endline. RESULTS Women's knowledge of handwashing and infant/child feeding practices, and attitudes related to male involvement, consistently improved from baseline to midline and baseline to endline. Women's practices related to antenatal care, breastfeeding, and early child development improved from baseline to midline and baseline to endline. Improvements in KAP among male heads of household were varied across indicators with consistent improvement in practices related to child feeding practices from baseline to midline and baseline to endline. CONCLUSION Many changes in KAP were observed from baseline to midline and baseline to endline and corresponded with SBCC programming in the region. These results provide support for the value of large SBCC interventions. Public health efforts in settings such as Tanzania may benefit from adopting these approaches.

Abstract
IMPORTANCE Approximately 1 in 4 women experience intimate partner violence (IPV) or nonpartner sexual violence during their lifetime. Mothers exposed to IPV are more likely to experience depressive symptoms and to discipline their children harshly, which may affect their children's socioemotional development; however, there is limited evidence on these outcomes. OBJECTIVE To examine the association between IPV, maternal depressive symptoms, harsh child discipline, and child stimulation with child socioemotional development. DESIGN, SETTING, AND PARTICIPANTS This study used cross-sectional follow-up data collected from February 19 to October 10, 2014, from a birth cohort of children aged 18 to 36 months who were enrolled in a randomized, double-blind, placebo-controlled trial of neonatal vitamin A supplementation in the Morogoro region of Tanzania. Data analysis occurred between September 10, 2019, and January 20, 2020. EXPOSURES Lifetime experience of IPV was assessed using an abbreviated module of the Tanzania Demographic and Health Survey, maternal depressive symptoms were assessed with the Patient Health Questionnaire, and data on harsh child discipline and maternal stimulation of their children were collected using modules of the United Nations Children's Fund Multiple Indicator Cluster Survey. MAIN OUTCOMES AND MEASURES Child socioemotional development was measured by the Caregiver-Reported Early Childhood Development Instruments. RESULTS A total of 981 mother-child dyads were included in the analytic sample; 388 children (39.6%) were between ages 18 and 24 (mean [SD] age, 27.06 [6.08]) months, and 515 (52.5%) were male children. A negative association was observed between maternal report of physical IPV only (mean difference, -0.022; 95% CI, -0.045 to -0.006) and physical and sexual IPV (mean difference, -0.045; 95% CI, -0.077 to -0.013) with child socioemotional scores, but neither was statistically significant after including depressive symptoms in the model, which is consistent with mediation. Furthermore, a negative association was observed between maternal mild to severe depressive symptoms and child socioemotional development, including adjustment for IPV (mean difference, -0.073; 95% CI, -0.103 to -0.043). Harsh disciplinary practices and stimulation were not associated with child socioemotional development after adjusting for IPV, maternal depressive symptoms, and other factors. CONCLUSIONS AND RELEVANCE The findings of this study suggest that maternal depressive symptoms may explain the negative association between IPV and child socioemotional development.

Promoting Caregiver Early Childhood Development Behaviors through Social and Behavioral Change Communication Program in Tanzania. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19095149. [PMID: 35564545 PMCID: PMC9103222 DOI: 10.3390/ijerph19095149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 04/15/2022] [Accepted: 04/20/2022] [Indexed: 12/04/2022]
Abstract
Objectives: Stunting remains a prevalent issue in Tanzania. The consequences of stunting include reduced height, greater susceptibility to disease, and diminished cognitive ability throughout the lifespan. Lack of psychosocial stimulation is associated with increased stunting, particularly in terms of its cognitive impact. The Addressing Stunting in Tanzania Early (ASTUTE) program was a large social and behavior change communication (SBCC) intervention that aimed to reduce childhood stunting in the region by targeting early childhood development (ECD) behaviors. The purpose of this study is to report on the extent to which exposure to ASTUTE might be related to ECD behaviors. Methods: ASTUTE disseminated program messages via a mass media campaign and interpersonal communication (IPC). Logistic regression models were used to explore the relationship between exposure to TV, radio, IPC messages, and key ECD behaviors of female primary caregivers and male heads of household. Results: Among primary caregivers, IPC was positively associated with all ECD behaviors measured. Radio was associated with all behaviors except drawing with their child. TV was associated with all behaviors except playing with their child. Among heads of household, only the radio was positively associated with the ECD behaviors measured. Conclusions for practice: Findings indicate that SBCC interventions that include mass media and IPC components may be effective at promoting parental engagement in ECD behaviors. Significance: We know that ECD is important for a child’s development. We know that parents play a critical role in promoting ECD behaviors. We are still exploring ways to influence parents so that they are more involved in ECD behaviors. The results presented here provide evidence for successful mass media and IPC efforts to improve parents’ ECD behaviors. We hope this study will add more evidence for large interventions such as these to the literature, and we are very hopeful that governments and large international NGOs will prioritize SBCC approaches in the future, especially in locations where face-to-face interventions may be challenging.

Effects of vitamin and mineral supplementation during pregnancy on maternal, birth, child health and development outcomes in low- and middle-income countries: A systematic review. CAMPBELL SYSTEMATIC REVIEWS 2021; 17:e1127. [PMID: 37051178 PMCID: PMC8356361 DOI: 10.1002/cl2.1127] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Indexed: 05/04/2023]
Abstract
Background Almost two billion people who are deficient in vitamins and minerals are women and children in low- and middle-income countries (LMIC). These deficiencies are worsened during pregnancy due to increased energy and nutritional demands, causing adverse outcomes in mother and child. To reduce micronutrient deficiencies, several strategies have been implemented, including diet diversification, large-scale and targeted fortification, staple crop bio-fortification and micronutrient supplementation. Objectives To evaluate and summarize the available evidence on the effects of micronutrient supplementation during pregnancy in LMIC on maternal, fetal, child health and child development outcomes. This review will assess the impact of single micronutrient supplementation (calcium, vitamin A, iron, vitamin D, iodine, zinc, vitamin B12), iron-folic acid (IFA) supplementation, multiple micronutrient (MMN) supplementation, and lipid-based nutrient supplementation (LNS) during pregnancy. Search Methods We searched papers published from 1995 to 31 October 2019 (related programmes and good quality studies pre-1995 were limited) in CAB Abstracts, CINAHL, Cochrane Central Register of Controlled Trials, Embase, International Initiative for Impact Evaluations, LILACS, Medline, POPLINE, Web of Science, WHOLIS, ProQuest Dissertations & Theses Global, R4D, WHO International Clinical Trials Registry Platform. Non-indexed grey literature searches were conducted using Google, Google Scholar, and web pages of key international nutrition agencies. Selection Criteria We included randomized controlled trials (individual and cluster-randomized) and quasi-experimental studies that evaluated micronutrient supplementation in healthy, pregnant women of any age and parity living in a LMIC. LMIC were defined by the World Bank Group at the time of the search for this review. While the aim was to include healthy pregnant women, it is likely that these populations had one or more micronutrient deficiencies at baseline; women were not excluded on this basis. Data Collection and Analysis Two authors independently assessed studies for inclusion and risk of bias, and conducted data extraction. Data were matched to check for accuracy. Quality of evidence was assessed using the GRADE approach. Main Results A total of 314 papers across 72 studies (451,723 women) were eligible for inclusion, of which 64 studies (439,649 women) contributed to meta-analyses. Seven studies assessed iron-folic acid (IFA) supplementation versus folic acid; 34 studies assessed MMN vs. IFA; 4 studies assessed LNS vs. MMN; 13 evaluated iron; 13 assessed zinc; 9 evaluated vitamin A; 11 assessed vitamin D; and 6 assessed calcium. Several studies were eligible for inclusion in multiple types of supplementation. IFA compared to folic acid showed a large and significant (48%) reduction in the risk of maternal anaemia (average risk ratio (RR) 0.52, 95% CI 0.41 to 0.66; studies = 5; participants = 15,540; moderate-quality evidence). As well, IFA supplementation demonstrated a smaller but significant, 12% reduction in risk of low birthweight (LBW) babies (average RR 0.88, 95% CI 0.78 to 0.99; studies = 4; participants = 17,257; high-quality evidence). MMN supplementation was defined as any supplement that contained at least 3 micronutrients. Post-hoc analyses were conducted, where possible, comparing the differences in effect of MMN with 4+ components and MMN with 3 or 4 components. When compared to iron with or without FA, MMN supplementation reduced the risk of LBW by 15% (average RR 0.85, 95% CI 0.77 to 0.93; studies = 28; participants = 79,972); this effect was greater in MMN with >4 micronutrients (average RR 0.79, 95% CI 0.71 to 0.88; studies = 19; participants = 68,138 versus average RR 1.01, 95% CI 0.92 to 1.11; studies = 9; participants = 11,834). There was a small and significant reduction in the risk of stillbirths (average RR 0.91; 95% CI 0.86 to 0.98; studies = 22; participants = 96,772) and a small and significant effect on the risk of small-for-gestational age (SGA) (average RR 0.93; 95% CI 0.88 to 0.98; studies = 19; participants = 52,965). For stillbirths and SGA, the effects were greater among those provided MMN with 4+ micronutrients. Children whose mothers had been supplemented with MMN, compared to IFA, demonstrated a 16% reduced risk of diarrhea (average RR 0.84; 95% CI 0.76 to 0.92; studies = 4; participants = 3,142). LNS supplementation, compared to MMN, made no difference to any outcome; however, the evidence is limited. Iron supplementation, when compared to no iron or placebo, showed a large and significant effect on maternal anaemia, a reduction of 47% (average RR 0.53, 95% CI 0.43 to 0.65; studies = 6; participants = 15,737; moderate-quality evidence) and a small and significant effect on LBW (average RR 0.88, 95% CI 0.78 to 0.99; studies = 4; participants = 17,257; high-quality evidence). Zinc and vitamin A supplementation, each both compared to placebo, had no impact on any outcome examined with the exception of potentially improving serum/plasma zinc (mean difference (MD) 0.43 umol/L; 95% CI -0.04 to 0.89; studies = 5; participants = 1,202) and serum/plasma retinol (MD 0.13 umol/L; 95% CI -0.03 to 0.30; studies = 6; participants = 1,654), respectively. When compared to placebo, vitamin D supplementation may have reduced the risk of preterm births (average RR 0.64; 95% CI 0.40 to 1.04; studies = 7; participants = 1,262), though the upper CI just crosses the line of no effect. Similarly, calcium supplementation versus placebo may have improved rates of pre-eclampsia/eclampsia (average RR 0.45; 95% CI 0.19 to 1.06; studies = 4; participants = 9,616), though the upper CI just crosses 1. Authors' Conclusions The findings suggest that MMN and vitamin supplementation improve maternal and child health outcomes, including maternal anaemia, LBW, preterm birth, SGA, stillbirths, micronutrient deficiencies, and morbidities, including pre-eclampsia/eclampsia and diarrhea among children. MMN supplementation demonstrated a beneficial impact on the most number of outcomes. In addition, MMN with >4 micronutrients appeared to be more impactful than MMN with only 3 or 4 micronutrients included in the tablet. Very few studies conducted longitudinal analysis on longer-term health outcomes for the child, such as anthropometric measures and developmental outcomes; this may be an important area for future research. This review may provide some basis to guide continual discourse around replacing IFA supplementation with MMN along with the use of single micronutrient supplementation programs for specific outcomes.

Abstract
OBJECTIVE This study was conducted to evaluate the relationship between DHA and development of motoric, cognitive, and socioemotional (DMCS) at infant 18-23 months of age. METHODS This was a cohort study following a supplementation to pregnant and lactating mothers with Moringa oleifera leaf (MOL) or iron folic acid (IFA). DHA in breastmilk was measured at 6 months of age (n=64). DMCS was measured at their age 18-23 months using CREDI (Caregiver Reported Early Childhood Development Index). All measurements were assessed by trained field workers using a standard questionnaire and data was analyzed using Spearman Correlation. RESULTS Majority of mothers were between 20 and 35yr old (71.9%), less than 12yr of education (71.9%), household wife (84.4%), and from farmers family (40.6%). There were borderline significant relationships between DHA levels and cognitive and motoric score (p=0.096, r=0.210 and p=0.064, r=0.233 respectively for cognitive and motoric). However, there was a significant relationship between DHA and socioemotional score (p=0.049, r=0.247). CONCLUSION We conclude that DHA in breastmilk 6 months would predict the development of motoric, cognitive, and socioemotional of infant at the period of 18-23 months of age.

Abstract
Reflecting a burgeoning political interest in supporting young children around the world, global demand for reliable, valid, and scalable assessments of early childhood development (ECD) is on the rise. One of the more popular sets of tools for measuring the ECD of children under age 3 is the Caregiver Reported Early Development Instruments (CREDI), which includes both a long form for research and evaluation and a short form for population-level monitoring. In this commentary, we describe the goals and limitations of the CREDI, research to support its use as a population-level ECD instrument, as well as the major gaps in its evidence base. We also discuss how the work of Alderman and colleagues (in this issue) addresses some of these outstanding gaps, highlighting several critical areas for future research.

Abstract
BACKGROUND It has been suggested that low serum zinc levels may be associated with suboptimal outcomes of pregnancy, such as prolonged labour, atonic postpartum haemorrhage, pregnancy-induced hypertension, preterm labour and post-term pregnancies, although these associations have not yet been established. This is an update of a review first published in 1997 and subsequently updated in 2007, 2012 and 2015. OBJECTIVES 1. To compare the effects on maternal, fetal, neonatal and infant outcomes in healthy pregnant women receiving zinc supplementation versus no zinc supplementation, or placebo. 2. To assess the above outcomes in a subgroup analysis reviewing studies performed in women who are, or are likely to be, zinc-deficient. SEARCH METHODS For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (3 July 2020), and reference lists of retrieved studies. SELECTION CRITERIA Randomised trials of zinc supplementation versus no zinc supplementation or placebo administration during pregnancy, earlier than 27 weeks' gestation. We excluded quasi-randomised controlled trials. We intended to include studies presented only as abstracts, if they provided enough information or, if necessary, by contacting authors to analyse them against our criteria; we did not find any such studies. DATA COLLECTION AND ANALYSIS Three review authors applied the study selection criteria, assessed trial quality and extracted data. When necessary, we contacted study authors for additional information. We assessed the certainty of the evidence using GRADE. MAIN RESULTS For this update, we included 25 randomised controlled trials (RCTs) involving over 18,000 women and their babies. The overall risk of bias was low in half of the studies. The evidence suggests that zinc supplementation may result in little or no difference in reducing preterm births (risk ratio (RR) 0.87, 95% confidence interval (CI) 0.74 to 1.03; 21 studies, 9851 participants; low-certainty evidence). Further, zinc supplementation may make little or no difference in reducing the risk of stillbirth (RR 1.22, 95% CI 0.80 to 1.88; 7 studies, 3295 participants; low-certainty evidence), or perinatal deaths (RR 1.10, 95% CI 0.81 to 1.51; 2 studies, 2489 participants; low-certainty evidence). It is unclear whether zinc supplementation reduces neonatal death, because the certainty of the evidence is very low. Finally, for other birth outcomes, zinc supplementation may make little or no difference to mean birthweight (MD 13.83, 95% CI -15.81 to 43.46; 22 studies, 7977 participants; low-certainty evidence), and probably makes little or no difference in reducing the risk of low birthweight (RR 0.94, 95% CI 0.79 to 1.13; 17 studies, 7399 participants; moderate-certainty evidence) and small-for-gestational age babies when compared to placebo or no zinc supplementation (RR 1.02, 95% CI 0.92 to 1.12; 9 studies, 5330 participants; moderate-certainty evidence). We did not conduct subgroup analyses, as very few studies used normal zinc populations. AUTHORS' CONCLUSIONS There is not enough evidence that zinc supplementation during pregnancy results in improvements in maternal or neonatal outcomes. Future research to address ways of improving the overall nutritional status of pregnant women, particularly in low-income regions, and not looking at zinc in isolation, should be an urgent priority.

Abstract
Infants born with congenital heart disease (CHD) are at increased risk of neurodevelopmental difficulties in childhood. The extent to which perioperative factors, cardiac physiology, brain injury severity, socioeconomic status, and home environment influence early neurodevelopment is not clear. Sixty-nine newborns with CHD were recruited from St Thomas' Hospital. Infants underwent presurgical magnetic resonance imaging on a 3-Tesla scanner situated on the neonatal unit. At 22 months, children completed the Bayley Scales of Infant and Toddler Development-3rd edition and parents completed the cognitively stimulating parenting scale to assess cognitive stimulation at home. Level of maternal education and total annual household income were also collected. Hospital records were reviewed to calculate days on the intensive care unit post-surgery, time on bypass during surgery, and days to corrective or definitive palliative surgical intervention. In the final analysis of 56 infants, higher scores on the cognitively stimulating parenting scale were associated with higher cognitive scores at age 22 months, correcting for gestational age at birth, sex, and maternal education. There were no relationships between outcome scores and clinical factors; socioeconomic status; or brain injury severity. Supporting parents to provide a stimulating home environment for children may promote cognitive development in this high-risk population.

French B, Outhwaite LA, Langley-Evans SC, Pitchford NJ. Nutrition, growth, and other factors associated with early cognitive and motor development in Sub-Saharan Africa: a scoping review. J Hum Nutr Diet 2020; 33:644-669. [PMID: 32734599 DOI: 10.1111/jhn.12795] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 06/05/2020] [Accepted: 06/08/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Food insecurity, poverty and exposure to infectious disease are well-established drivers of malnutrition in children in Sub-Saharan Africa. Early development of cognitive and motor skills - the foundations for learning - may also be compromised by the same or additional factors that restrict physical growth. However, little is known about factors associated with early child development in this region, which limits the scope to intervene effectively. To address this knowledge gap, we compared studies that have examined factors associated with early cognitive and/or motor development within this population. METHODS Predetermined criteria were used to examine four publication databases (PsycInfo, Embase, Web of Science and Medline) and identify studies considering the determinants of cognitive and motor development in children aged 0-8 years in Sub-Saharan Africa. RESULTS In total, 51 quantitative studies met the inclusion criteria, reporting on 30% of countries across the region. Within these papers, factors associated with early child development were grouped into five themes: Nutrition, Growth and Anthropometry, Maternal Health, Malaria and HIV, and Household. Food security and dietary diversity were associated with positive developmental outcomes, whereas exposure to HIV, malaria, poor maternal mental health, poor sanitation, maternal alcohol abuse and stunting were indicators of poor cognitive and motor development. DISCUSSION In this synthesis of research findings obtained across Sub-Saharan Africa, factors that restrict physical growth are also shown to hinder the development of early cognitive and motor skills, although additional factors also influence early developmental outcomes. The study also reviews the methodological limitations of conducting research using Western methods in sub-Saharan Africa.

[PMID: 31738767 PMCID: PMC6860446 DOI: 10.1371/journal.pone.0223056] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Accepted: 09/12/2019] [Indexed: 11/19/2022] Open
Abstract
This study examined variation in the timing of 5,447 infants' and toddlers' reported acquisition of 12 basic social-emotional skills across and within 11 developing and developed country sites. Although children differed significantly across sites in when they attained social-emotional skills on average (e.g., M age Brazil = 20.50 months vs. M age India = 26.92 months), there was also substantial heterogeneity across skills. For example, children in Pakistan were reported to demonstrate sympathy on average seven months earlier than their peers in Ghana, whereas the opposite was true for sharing. Overall, country-level health and education were strongly associated (r > .60) with earlier site-level skill attainment. In addition to heterogeneity across sites, we also observed notable within-site variability in skill development (ICCs = .03 to .38). Future research is needed to identify sources of variability and how to promote skills that matter within a given context.
