Antenatal care is associated with adherence to iron supplementation among pregnant women in selected low-middle-income-countries of Asia, Africa, and Latin America & the Caribbean regions: Insights from Demographic and Health Surveys.

Anaemia is a global public health problem affecting 800 million women and children globally. Anaemia is associated with perinatal mortality, child morbidity and mortality, mental development, immune competence, susceptibility to lead poisoning and performance at work. The objective of this article is to identify whether antenatal care-seeking was associated with the uptake of iron supplementation among pregnant women, adjusting for a range of covariates. This article used data from the cross-sectional recent Demographic and Health Surveys (DHS) of 12 countries in Asia, Africa and Latin America & the Caribbean regions. The individual-level data from 273,144 women of reproductive age (15-49 years) were analysed from multi-country DHS. Multiple Logistic regression analyses were conducted using Predictive Analytics Software for Windows (PASW), Release 18.0. Receiving at least four antenatal care visits was significantly associated with the consumption of 90 or more iron-containing supplements in 12 low and middle income countries across three regions after adjusting for different household and respondent characteristics, while mass media exposure was found to be a significant predictor in India and Indonesia. Antenatal care seems to be the most important predictor of adherence to iron intake in the selected countries across Africa, Asia, Latin America and Caribbean regions.

Tanzanian men's engagement in household chores is associated with improved antenatal care seeking and maternal health.

BACKGROUND: Male support for partners' antenatal care (ANC) has the potential to improve women's care-seeking and maternal health outcomes. This study describes factors that are associated with men's involvement in household tasks and explores the relationship between men's help with tasks and women's ANC-seeking, diet and workload during pregnancy as well as other health behaviors. METHODS: This study was conducted in five Lake Zone regions of Tanzania. Cross-sectional surveys were carried out among approximately 10,000 households that had children under the age of 2 years. Surveys were administered to mothers of children less than 2 years and where available, their male partners. Data were collected between December 2015 and May 2020, in conjunction with a large-scale campaign aimed at reducing childhood stunting by changing the behavior of mothers, caregivers, and decision makers. Data analysis included bivariate analysis and logistic regression modeling. RESULTS: Men's engagement in household activities was significantly associated with living in an urban setting, being younger, having at least some formal schooling, early verbal interactions with their children, and male involvement in healthcare decisions. Additionally, mothers of male partners that were engaged in household activities were significantly older and more likely to have at least some secondary school education. Relative to households where men only infrequently helped out with chores or not at all, women from households where men frequently helped were significantly more likely to have taken iron tablets during pregnancy, report having eaten more than usual, lessening their household workload during their most recent pregnancy, and more likely to have played with their child in the week prior to the survey. CONCLUSION: Male's participation in household tasks is associated with a general improvement in mother's ANC behaviors. Implicit in these findings is that general primary education for both men and women has health benefits that transcend socioeconomic class and that future interventions aimed to engage males in household tasks may target older males with less education living in rural areas.

Engaging fathers to improve complementary feeding is acceptable and feasible in the Lake Zone, Tanzania.

In Tanzania, suboptimal complementary feeding practices contribute to high stunting rates. Fathers influence complementary feeding practices, and effective strategies are needed to engage them. The objectives of this research were to examine the acceptability and feasibility of (1) tailored complementary feeding recommendations and (2) engaging fathers in complementary feeding. We conducted trials of improved practices with 50 mothers and 40 fathers with children 6-18 months. At visit 1, mothers reported current feeding practices and fathers participated in focus group discussions. At visit 2, mothers and fathers received individual, tailored counselling and chose new practices to try. After 2 weeks, at visit 3, parents were interviewed individually about their experiences. Interview transcripts were analysed thematically. The most frequent feeding issues at visit 1 were the need to thicken porridge, increase dietary diversity, replace sugary snacks and drinks and feed responsively. After counselling, most mothers agreed to try practices to improve diets and fathers agreed to provide informational and instrumental support for complementary feeding, but few agreed to try feeding the child. At follow-up, mothers reported improved child feeding and confirmed fathers' reports of increased involvement. Most fathers purchased or provided funds for recommended foods; some helped with domestic tasks or fed children. Many participants reported improved spousal communication and cooperation. Families were able to practice recommendations to feed family foods, but high food costs and seasonal unavailability were challenges. It was feasible and acceptable to engage fathers in complementary feeding, but additional strategies are needed to address economic and environmental barriers.

Importance of authorship and inappropriate authorship assignment in paediatric research in low- and middle-income countries.

OBJECTIVE: To understand the importance of authorship and authorship position, and gauge perceptions of inappropriate authorship assignment, among authors publishing paediatric research conducted in low- and middle-income countries (LMICs). METHODS: We conducted a cross-sectional, mixed-methods study using an online survey of both corresponding and randomly selected, non-corresponding authors who published research conducted in LMICs from 2006 to 2015 in the top four paediatric journals by Eigenfactor score. We used chi-square tests to compare responses by authors living in LMICs to authors living in high-income countries (HICs). We analysed qualitative responses using thematic analysis. RESULTS: Of 1420 potential respondents, 19.6% (n = 279) completed the survey. 57% (n = 159) lived in LMICs and 43% (n = 120) in HICs. LMIC authors more commonly perceived first authorship as most important for their academic advancement than HIC authors (74.2% vs. 60.8%, P = 0.017), while HIC authors reported last authorship as most important (25.1% vs. 38.3%, P = 0.018). 65% (n = 181) of respondents believed that their collaborators had been inappropriately assigned authorship positions (no difference in LMIC and HIC responses) and 32.6% (n = 91) reported personally accepting inappropriate authorship positions (more common in HIC respondents, P = 0.005). In qualitative data, respondents questioned the applicability of standard authorship guidelines for collaborative research conducted in LMICs. CONCLUSIONS: LMIC and HIC authors held different perceptions about the importance of authorship position. Reported inappropriate authorship assignment was common among both LMIC and HIC respondents. Alternatives to standard authorship criteria for research conducted in LMICs merit further studies.

OBJECTIF: Comprendre l'importance de la paternité d'auteur et de la position de l'auteur, et évaluer les perceptions de l'attribution inappropriée de la paternité d'auteur parmi les auteurs qui publient des recherches pédiatriques menées dans des pays à revenu faible ou intermédiaire (PRFI). MÉTHODES: Nous avons mené une étude transversale à méthodes mixtes avec un sondage en ligne auprès d'auteurs de correspondance et sélectionnés au hasard, d'auteurs not de correspondance, ayant publié des recherches menées dans des PRFIde 2006 à 2015 dans les quatre revues pédiatriques les mieux classées par le score d'Eigenfactor. Nous avons utilisé des tests de chi carré pour comparer les réponses des auteurs des PRFI à ceux des aux auteurs des pays à revenu élevé (PRE). Nous avons analysé les réponses qualitatives à l'aide d'une analyse thématique. RÉSULTATS: Sur 1.420 répondants potentiels, 19,6% (n = 279) ont répondu au sondage. 57% (n = 159) vivaient dans des PRFI et 43% (n = 120) dans des PRE. Les auteurs des PRFI estimaient plus souvent que la position de premier auteur était le plus important pour leur avancement universitaire que les auteurs des PRE (74,2% contre 60,8%, P = 0,017), tandis que les auteurs desPRE ont déclaré que le dernier auteur était le plus important (25,1% contre 38,3%, P = 0,018). 65% (n = 181) des répondants estimaient que des positions d'auteur avaient été attribués de manière inappropriée à leurs collaborateurs (aucune différence entre les réponses des PRFI et des PRE) et 32,6% (n = 91) ont déclaré avoir personnellement accepté des positions d'auteurs inappropriées (plus fréquents chez les répondants desPRE, P = 0,005). En ce qui concerne les données qualitatives, les répondants se sont interrogés sur l'applicabilité des directives standards en matière de paternité d'auteur pour la recherche collaborative menée dans les PRFI. CONCLUSIONS: Les auteurs des PRFI et desPREont des perceptions différentes sur l'importance de la position de l'auteur. L'attribution inappropriée de laposition d'auteur signalée était fréquente chez les répondants des PRFI et des PRE. Les alternatives aux critères standards de la paternité d'auteur pour les recherches menées dans les PRFI méritent d'être approfondies.

Authorship in paediatric research conducted in low- and middle-income countries: parity or parasitism?

OBJECTIVES: Interest in global health has increased greatly in the past two decades. Concomitantly, the number and complexity of research partnerships between high-income (HIC) and low- and middle-income countries (LMICs) has grown. We aimed to determine whether there is authorship parity (equitable representation and author order) or parasitism (no authors from study countries) in paediatric research conducted in LMICs. METHODS: We reviewed all articles published from 2006 to 2015 in the four paediatric journals with the highest Eigenfactor scores. We limited our review to articles from LMICs and abstracted information on author affiliation and order, funding source and study design. We calculated Student's t-tests and chi-square using Fisher's exact test with Monte Carlo estimates. RESULTS: There were 24 169 articles published during the study period, and 1243 met inclusion criteria. Of those, 95.9% (n = 1,192) included at least one author affiliated with a LMIC. Among multicountry studies (n = 165), 40.4% did not include authors from every LMIC involved. Of the 9876 authors, most were affiliated with institutions from upper-middle-income countries (41.7%) and HICs (32.7%), with far fewer affiliated with lower middle-income (15.5%) and low-income countries (5.4%) (P < 0.001). In articles from low-income countries, first and last authors from HICs were more common than authors with low-income country affiliations (P < 0.001). CONCLUSIONS: Authorship parasitism was rare overall but common in multicountry studies. In studies conducted in low-income countries, HIC authors more commonly occupied first and last author positions than authors from the study countries. Where LMIC authors make substantial contributions, researchers should strive for authorship parity.

Children with access to improved sanitation but not improved water are at lower risk of stunting compared to children without access: a cohort study in Ethiopia, India, Peru, and Vietnam.

BACKGROUND: This study's purpose was to understand associations between water, sanitation, and child growth. METHODS: We estimated stunting (height-for-age Z score <-2 SD) and thinness (BMI-Z <-2 SD) risk ratios using data from 7,715 Ethiopian, Indian, Peruvian, and Vietnamese children from the Young Lives study. RESULTS: In unadjusted models, household access to improved water and toilets was often associated with reduced stunting risk. After adjusting for child, household, parent, and community variables, access to improved water was usually not associated with stunting nor thinness except in Ethiopia where access to improved water was associated with reduced stunting and thinness at 1y and 5y. In contrast, in both unadjusted and adjusted models, stunting at 1y was less common among children with good toilet access than among those without access and this difference persisted when children were 5y and 8y. For example, in adjusted estimates, Vietnamese 5y olds with access to improved toilets had relative stunting risk at 8y 0.62-0.68 that of 5y olds with no access to improved toilets. Water and toilets were rarely associated with thinness. CONCLUSIONS: Results from our study indicate that access to improved sanitation is more frequently associated with reduced stunting risk than access to improved water. However, additional studies are needed before drawing definitive conclusions about the impact of toilets relative to water. This study is the first to our knowledge to demonstrate the robust and persistent importance of access to improved toilets in infancy, not only during the first year but continuing into childhood. Additional longitudinal investigations are needed to determine concurrent and long-term associations of WASH with stunting and thinness.

Stunting in Infancy Is Associated with Decreased Risk of High Body Mass Index for Age at 8 and 12 Years of Age.

BACKGROUND: Effects of early-life stunting on adiposity development later in childhood are not well understood, specifically with respect to age in the onset of overweight and obesity. OBJECTIVES: We analyzed associations of infant stunting with prevalence of, incidence of, and reversion from high body mass index-for-age z score (BMIZ) later in life. We then estimated whether associations of infant stunting with BMIZ varied by sex, indigenous status, and rural or urban residence. METHODS: Data were collected from 1942 Peruvian children in the Young Lives cohort study at ages 1, 5, 8, and 12 y. Multivariable generalized linear models estimated associations of stunting (height-for-age z score <-2) at age 1 y with risk of BMIZ > 1 and BMIZ > 2 prevalence, incidence (moving above a BMIZ threshold between ages), and reversion (moving below a BMIZ threshold between ages) at later ages. RESULTS: After adjustment for covariates, stunting at age 1 y was associated with a lower prevalence of BMIZ > 1 at age 8 y (RR: 0.81; 95% CI: 0.66, 1.00; P = 0.049) and 12 y (RR: 0.75; 95% CI: 0.61, 0.91; P = 0.004), as well as a lower prevalence of BMIZ > 2 at age 8 y. Stunting was not associated with incident risk of BMIZ > 1 or BMIZ > 2. Stunting was positively associated at age 5 y with risk of reversion from BMIZ > 1 (RR: 1.22; 95% CI: 1.05, 1.42; P = 0.008) and BMIZ > 2. We found evidence that the association of stunting with prevalent and incident BMIZ > 1 was stronger for urban children at ages 5 and 8 y, and for nonindigenous children at age 8 y. CONCLUSIONS: Stunting predicted a lower risk of prevalent BMIZ > 1 and BMIZ > 2, even after controlling for potential confounders. This finding may be driven in part by a higher risk of reversion from BMIZ > 1 by age 5 y. Our results contribute to an understanding of how nutritional stunting in infancy is associated with BMIZ later in life.

Does pre-school improve cognitive abilities among children with early-life stunting? A longitudinal study for Peru.

Several studies in developing countries have found that children who experience growth faltering in the first years of life show lower cognitive abilities than their peers. In this study, we use the Young Lives longitudinal dataset in Peru to analyze if attending pre-school affects cognitive abilities at age five years, and if there is an interaction with HAZ at age one year. Using instrumental variables we found, for receptive vocabulary, a positive effect of attending Jardines (formal) pre-schools; the effect of attending PRONOEI (community-based) pre-schools was not significant. More years attending Jardines was more beneficial for children who were better nourished. We suggest working to improve the quality of PRONOEIs, and with teachers on targeting children of lower nutritional status.

Cross-Sectional and Longitudinal Associations between Household Food Security and Child Anthropometry at Ages 5 and 8 Years in Ethiopia, India, Peru, and Vietnam.

BACKGROUND: Poor childhood nutritional status has lifetime effects and food insecurity is associated with dietary practices that can impair nutritional status. OBJECTIVES: We assessed concurrent and subsequent associations between food insecurity and height-for-age z scores (HAZs) and body mass index-for-age z scores (BMI-Zs); evaluated associations with transitory and chronic food insecurity; and tested whether dietary diversity mediates associations between food insecurity and nutritional status. METHODS: We used data from the Young Lives younger cohort composed of children in Ethiopia (n = 1757), India (n = 1825), Peru (n = 1844), and Vietnam (n = 1828) recruited in 2002 (round 1) at ∼1 y old, with subsequent data collection at 5 y in 2006 (round 2) and 8 y in 2009 (round 3). RESULTS: Children from food-insecure households had significantly lower HAZs in all countries at 5 y (Ethiopia, -0.33; India, -0.53; Peru, -0.31; and Vietnam, -0.68 HAZ; all P < 0.001), although results were attenuated after controlling for potential confounders (Ethiopia, -0.21; India, -0.32; Peru, -0.14; and Vietnam, -0.27 HAZ; P < 0.01). Age 5 y food insecurity predicted the age 8 y HAZ, but did not add predictive power beyond HAZ at age 5 y in Ethiopia, India, or Peru. Age 5 y food insecurity predicted the age 8 y BMI-Z even after controlling for the 5 y BMI-Z, although associations were not significant after the inclusion of additional confounding variables (Ethiopia, P = 0.12; India, P = 0.29; Peru, P = 0.16; and Vietnam, P = 0.51). Chronically food-insecure households had significantly lower HAZs than households that were consistently food-secure, although BMI-Zs did not differ by chronic food-insecurity status. Dietary diversity mediated 18.8-30.5% of the association between food security and anthropometry in Vietnam, but mediated to a lesser degree (8.4-19.3%) in other countries. CONCLUSIONS: In 4 countries, food insecurity at 5 y of age was associated with both HAZ and BMI-Z at age 8 y, although the association was attenuated after adjusting for other household factors and anthropometry at age 5 y, and remained significant only for the HAZ in Vietnam.

Participation in the Juntos Conditional Cash Transfer Program in Peru Is Associated with Changes in Child Anthropometric Status but Not Language Development or School Achievement.

BACKGROUND: It is unclear what effects a conditional cash transfer (CCT) program would have on child anthropometry, language development, or school achievement in the context of the nutrition transition experienced by many low- and middle-income countries. OBJECTIVE: We estimated the association of participation in Peru's Juntos CCT with anthropometry, language development, and school achievement among children aged 7-8 y. METHODS: We used data from the Young Lives Study of a cohort born between 2001 and 2002. We estimated associations of the Juntos program with height-for-age z score (HAZ), body mass index-for-age z score (BAZ), stunting, and overweight at age 7-8 y separately for children participating in the program for ≥2 y (n = 169) and children participating for <2 y (n = 188). We then estimated associations with receptive vocabulary and grade achievement among children who had been assessed at age 4-6 y before enrollment in Juntos (n = 243). We identified control subjects using propensity score matching and conducted difference-in-differences comparisons. RESULTS: Juntos participation was associated with increases in HAZ among boys participating for ≥2 y [average effect of treatment among the treated (ATT): 0.43; 95% CI: 0.09, 0.77; P = 0.01] and for boys participating for <2 y (ATT: 0.52; 95% CI: 0.23, 0.80; P < 0.01). Among girls participating in the program for ≥2 y, BAZ declined (ATT: -0.60; 95% CI: -1.00, -0.21; P < 0.01) as did the prevalence of overweight (ATT: -22.0 percentage points; 95% CI: -42.5, -2.7 percentage points; P = 0.03). We observed no significant associations of Juntos participation with receptive vocabulary or grade attainment. CONCLUSIONS: CCT program participation in Peru was associated with better linear growth among boys and decreased BAZ among girls, highlighting that a large-scale poverty-alleviation intervention may influence anthropometric outcomes in the context of the nutrition transition.

Growth faltering and recovery in children aged 1-8 years in four low- and middle-income countries: Young Lives.

OBJECTIVE: We characterized post-infancy child growth patterns and determined the incidence of becoming stunted and of recovery from stunting. DESIGN: Data came from Young Lives, a longitudinal study of childhood poverty in four low- and middle-income countries. SETTING: We analysed length/height measurements for children at ages 1, 5 and 8 years. SUBJECTS: Children (n 7171) in Ethiopia, India, Peru and Vietnam. RESULTS: Mean height-for-age Z-score (HAZ) at age 1 year ranged from -1·51 (Ethiopia) to -1·08 (Vietnam). From age 1 to 5 years, mean HAZ increased by 0·27 in Ethiopia (P < 0·001) and decreased among the other cohorts (range: -0·19 (Peru) to -0·32 (India); all P < 0·001). From 5 to 8 years, mean HAZ increased in all cohorts (range: 0·19 (India) to 0·38 (Peru); all P < 0·001). Prevalence of stunting (HAZ<-2·0) at 1 year ranged from 21 % (Vietnam) to 46 % (Ethiopia). From age 1 to 5 years, stunting prevalence decreased by 15·1 percentage points in Ethiopia (P < 0·001) and increased in the other cohorts (range: 3·0 percentage points (Vietnam) to 5·3 percentage points (India); all P ≤ 0·001). From 5 to 8 years, stunting prevalence decreased in all cohorts (range: 5·0 percentage points (Vietnam) to 12·7 percentage points (Peru); all P < 0·001). The incidence of becoming stunted between ages 1 to 5 years ranged from 11 % (Vietnam) to 22 % (India); between ages 5 to 8 years, it ranged from 3 % (Peru) to 6 % (India and Ethiopia). The incidence of recovery from stunting between ages 1 and 5 years ranged from 27 % (Vietnam) to 53 % (Ethiopia); between ages 5 and 8 years, it ranged from 30 % (India) to 47 % (Ethiopia). CONCLUSIONS: We found substantial recovery from early stunting among children in four low- and middle-income countries.

What difference can fathers make? Early paternal absence compromises Peruvian children's growth.

Considerable evidence suggests that fathers' absence from home has a negative short- and long-term impact on children's health, psychosocial development, cognition and educational experience. We assessed the impact of father presence during infancy and childhood on children's height-for-age z-score (HAZ) at 5 years old. We conducted secondary data analysis from a 15-year cohort study (Young Lives) focusing on one of four Young Lives countries (Peru, n = 1821). When compared with children who saw their fathers on a daily or weekly basis during infancy and childhood, children who did not see their fathers regularly at either period had significantly lower HAZ scores (-0.23, P = 0.0094) after adjusting for maternal age, wealth and other contextual factors. Results also suggest that children who saw their fathers during childhood (but not infancy) had better HAZ scores than children who saw their fathers in infancy and childhood (0.23 z-score, P = 0.0388). Findings from analyses of resilient children (those who did not see their fathers at either round but whose HAZ > -2) show that a child's chances of not being stunted in spite of paternal absence at 1 and 5 years old were considerably greater if he or she lived in an urban area [odds ratio (OR) = 9.3], was from the wealthiest quintile (OR = 8.7) and lived in a food secure environment (OR = 3.8). Interventions designed to reduce malnutrition must be based on a fuller understanding of how paternal absence puts children at risk of growth failure.

The Impact of a Large-Scale Social and Behavior Change Communication Intervention in the Lake Zone Region of Tanzania on Knowledge, Attitudes, and Practices Related to Stunting Prevention.

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.

Promoting Caregiver Early Childhood Development Behaviors through Social and Behavioral Change Communication Program in Tanzania.

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.

Impact of early and concurrent stunting on cognition.

Undernutrition is associated with poor cognitive development, late entry into school, decreased years of schooling, reduced productivity and smaller adult stature. We use longitudinal data from 1674 Peruvian children participating in the Young Lives study to assess the relative impact of early stunting (stunted at 6-18 months of age) and concurrent stunting (stunted at 4.5-6 years of age) on cognitive ability. Anthropometric data were longitudinally collected for children at 6-18 months of age and 4.5-6 years of age at which time verbal and quantitative ability were also assessed. We estimate that an increase in concurrent height-for-age z-scores (HAZ) by one standard deviation was associated with an increase in a child's score on the Peabody Picture Vocabulary Test (PPVT) by 2.35 points [confidence interval (CI): 1.55-3.15] and a 0.16 point increase on the cognitive development assessment (CDA) (CI: 0.05-0.27). Furthermore, we report that the estimate for concurrent HAZ and PPVT is significantly higher than the estimate for early stunting and PPVT. We found no significant difference between early and concurrent estimates for HAZ and CDA. Children from older mothers, children whose mothers had higher education levels, children living in urban areas, children who attended pre-school, children with fewer siblings and children from wealthier backgrounds scored higher on both assessments. Cognitive skills of children entering school were associated with early stunting but the strongest association was found with concurrent stunting suggesting that interventions preventing linear growth faltering should not only focus on the under 2s but include children up to 5 years of age.

Health facility-based counselling and community outreach are associated with maternal dietary practices in a cross-sectional study from Tanzania.

BACKGROUND: Anemia and underweight among women are major public health challenges. Access to health services can improve dietary behaviors and women's nutritional status. We examined whether exposure to health services is associated with women's dietary practices in Tanzania. METHODS: Data come from a cross-sectional baseline survey among 5000 female primary caregivers who were randomly selected via two-stage sampling, prior to implementing a maternal and child nutrition program. We ran frequencies on women's exposure to existing health facility-based counselling, community health worker visits, and attendance at women's support groups. We examined associations between exposure to these interventions and maternal diets and adjusted for sociodemographic covariates using ordinary least squares regression and ordered logistic regression. RESULTS: A third of the sample (34.1%) had received any antenatal care (ANC) during their most recent pregnancy or had been advised by anyone about nutrition (37.0%). 68.0% had never had a community health worker (CHW) speak to them about their children's health and 9.4% had participated in a women's group. Only 8.0% of mothers ate more than usual during pregnancy and 7.1% ate more types of foods. After adjusting for mother's age, education and household assets, women who received nutrition advice were 1.3 times (95% CI: 1.1, 1.7) more likely than mothers who did not to eat more during pregnancy. Receiving antenatal care (ANC) and advice on nutrition before, during, and after pregnancy and delivery were highly associated with the mother eating more types of foods. Hearing from a CHW about children's health but not support group attendance was often associated with various dietary practices. Almost all measures of access to health services were significantly associated with mothers' frequency of eating in the previous 24 h. Receiving advice on nutrition during pregnancy and after giving birth and CHW contact were associated with mothers' dietary diversity in the previous 24 h. CONCLUSIONS: Several program exposure variables-especially being counselled about nutrition-were associated with improved dietary practices. Improving service delivery at scale may contribute to improved dietary behaviors in larger populations, given the associations we describe, along with findings from the existing literature.

Association between WASH-Related Behaviors and Knowledge with Childhood Diarrhea in Tanzania.

BACKGROUND: Diarrhea remains a major cause of morbidity and mortality among children in Tanzania. The purpose of this study was to explore associations between diarrheal disease and water, sanitation, and hygiene (WASH) related behaviors and determine care-seeking predictors for diarrheal disease. METHODS: Data from 9996 female primary caregivers were collected as part of a larger integrated nutrition program. Logistic regression was used to measure associations between predictor and dependent variables and diarrheal and care-seeking outcomes. RESULTS: Knowledge of the importance of handwashing after assisting a child who has defecated (OR 0.79, CI 0.72-0.87), before preparing food (OR 0.88, CI 0.80-0.97), and before feeding a child (OR 0.89, CI 0.81-0.99) were each associated with not having a child with diarrhea in the past two weeks. Fathers or male caregivers (OR 0.65, CI 0.48-0.89) were less likely to seek medical care for a child with diarrhea. No associations were found between WASH-related knowledge or behavior and seeking medical care for a child with diarrhea. CONCLUSIONS: Findings indicate that knowledge of handwashing importance was significant in washing hands after assisting a child who has defecated, before preparing food, and prior to feeding a child. These findings demonstrate the value of parental involvement to lower morbidity and mortality among children.

Children who recover from early stunting and children who are not stunted demonstrate similar levels of cognition.

Stunting is associated with adverse cognitive development in childhood and adolescence, fewer years of schooling, decreased productivity, and reduced adult stature. Recovery from early stunting is possible; however, few studies explore whether those who demonstrate linear catch-up growth experience long-term cognitive deficits. Using longitudinal data on 1674 Peruvian children from the Young Lives study, we identified factors associated with catch-up growth and assessed whether children who displayed catch-up growth have significantly lower cognition than children who were not stunted during infancy and childhood. Based on anthropometric data for children 6-18 mo of age and again for the same children when they were 4.5-6 y of age, we categorized participants as not stunted, stunted in infancy but not childhood (catch-up), stunted in childhood, and stunted in infancy and childhood. Children who had grandparents in the home, had less severe stunting in infancy, and had taller mothers were more likely to demonstrate catch-up growth by round 2. Children who experienced catch-up growth had verbal vocabulary and quantitative test scores that did not differ from children who were not stunted (P = 0.6 and P = 0.7, respectively). Those stunted in childhood as well as those stunted in infancy and childhood scored significantly lower on both assessments than children who were not stunted. Based on findings from this study, policy makers and program planners should consider redoubling efforts to prevent stunting and promote catch-up growth over the first few years of life as a way of improving children's physical and intellectual development.

Exploring the relationship between chronic undernutrition and asymptomatic malaria in Ghanaian children.

BACKGROUND: A moderate association has been found between asymptomatic parasitaemia and undernutrition. However, additional investigation using the gold standard for asymptomatic parasitaemia confirmation, polymerase chain reaction (PCR), is needed to validate this association. Anthropometric measurements and blood samples from children less than five years of age in a rural Ghanaian community were used to determine if an association exists between chronic undernutrition and PCR-confirmed cases of asymptomatic malaria. METHODS: This was a descriptive cross-sectional study of 214 children less than five years of age from a community near Kumasi, Ghana. Blood samples and anthropometric measurements from these children were collected during physical examinations conducted in January 2007 by partners of the Barekuma Collaborative Community Development Programme. RESULTS: Findings from the logistic model predicting the odds of asymptomatic malaria indicate that children who experienced mild, moderate or severe stunting were not more likely to have asymptomatic malaria than children who were not stunted. Children experiencing anaemia had an increased likelihood (OR = 4.15; 95% CI: 1.92, 8.98) of asymptomatic malaria. Similarly, increased spleen size, which was measured by ultrasound, was also associated with asymptomatic malaria (OR = 2.17; 95% CI: 1.44, 3.28). Fast breathing, sex of the child, and age of the child were not significantly associated with the asymptomatic malaria. CONCLUSIONS: No significant association between chronic undernutrition and presence of asymptomatic malaria was found. Children who experience anaemia and children who have splenomegaly are more likely to present asymptomatic malaria. Programmes aimed at addressing malaria should continue to include nutritional components, especially components that address anaemia.

Are Household Expenditures on Food Groups Associated with Children's Future Heights in Ethiopia, India, Peru, and Vietnam?

Household expenditure surveys, routinely conducted in low-and middle-income countries (LMICs), usually include questions pertaining to recent household expenditures on key food groups. When child anthropometrics are also available, such expenditure data can provide insights into household food purchasing patterns that are associated with subsequent child growth measures. We used data from 6993 children, born around 2001, from Ethiopia, India, Peru, and Vietnam, from the Young Lives younger cohort. We compared associations between two weeks of household food expenditures (in PPP-Purchasing Power Parity adjusted dollars) on food groups and child height-for-age-Z score (HAZ) at subsequent time points to assess longitudinal associations. Total food expenditures, rural/urban residence, maternal and paternal schooling, and child sex were included in our adjusted models because they may affect the relations between household food group expenditures and future child HAZ. In Ethiopia, India, and Peru every extra PPP$ spent on fats was associated with 0.02-0.07 higher future HAZ. In Vietnam every extra PPP$ spent on starches, was significantly associated with a 0.01 lower future HAZ. Across countries, different patterns of food expenditure and procurement may be differentially critical for predicting child HAZ. Our results demonstrate how expenditures on specific food groups can be associated with children's linear growth. This study provides additional evidence of the utility of longitudinal household food expenditure data in understanding child nutritional status.
