Background: Few studies have evaluated the dietary impact of complementary food supplements (CFSs) designed to deliver macro- and micronutrients to children at risk for undernutrition. In a randomized controlled trial in rural Bangladesh, we previously reported that CFSs increased children's micronutrient adequacy., Objective: To longitudinally characterize energy and macronutrient intakes and inadequacies and evaluate the extent to which CFSs fill intake gaps., Methods: Children were enrolled at 6 months and received one of four CFSs plus caregiver nutrition counseling or counseling alone for one year. A semi-quantitative diet questionnaire was administered at 6, 9, 12, 15, 18, and 24 months. Energy and macronutrient intakes were estimated by age and arm; protein adequacy was adjusted for protein quality and infection. We estimated the proportion meeting intake requirements set by FAO and the Institute of Medicine and compared group-wise differences using log binomial regression models with generalized estimating equations. We used multivariate analysis of variance models to evaluate if CFSs substituted home foods., Results: Across groups, most children did not meet energy or protein requirements at enrollment (74.6-81.3% and 77.4-79.2%, respectively). Estimated energy and macronutrient intakes from home foods increased from 6 to 24 months. Energy inadequacy was lower in the supplemented groups compared to the control at all ages (e.g., 10.5-13.8% versus 31.4% at 18 months). In the control group, protein inadequacy dropped from 78.4% at 6 months to 8.3% at 9 months to 2.8% by 18 months; adjusted protein estimates were 25.1% at 9 months and 7.0% at 18 months. Protein inadequacy was highest in the control group at all timepoints. CFSs did not substitute home foods., Conclusions: CFSs can significantly bridge energy and protein intake gaps. With earlier trial findings that CFSs filled micronutrient gaps and improved growth, these findings strengthen evidence supporting using CFSs for improved health outcomes., Clinical Trial Registry: NCT01562379, https://clinicaltrials.gov/ct2/show/NCT01562379., Competing Interests: Declaration of Competing Interest ☒ The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Parental feeding practices are associated with children's eating, but little is known about how childcare staff feeding practices relate to children's eating. The study examined the associations between childcare staff feeding practices and children's willingness-to-try-new-foods. Participants included children (n = 460), ages 3-5 years, and childcare staff (n = 91) recruited from 51 childcare centers in 10 Maryland counties. Feeding practices were measured using the Comprehensive Feeding Practices Questionnaire (CFPQ) adapted to the childcare setting. Children's willingness-to-try-new-foods was assessed using a food tasting activity administered in the childcare centers. Confirmatory and exploratory factor analyses were used to evaluate the factor structure of the CFPQ applied to childcare staff, and to identify modified factor structures. Logistic regressions assessed the association between childcare staff feeding practices and children's willingness-to-try-new-foods (categorized as high vs. low). Among this sample, a revised 7-factor, 32-item model, including encourage balance and variety, environment, healthy eating guidance, indulgent, monitoring, pressure, and restriction for health was identified. Children exposed to more indulgent feeding practices in the classroom had 2.13 (95% CI: 1.04, 4.37) times the odds of demonstrating high willingness-to-try-new-foods compared to children exposed to less frequent use of this feeding practice, with no associations among other feeding practices. Understanding mechanisms driving childcare staff feeding practices and their relation to children's eating behavior can inform interventions that promote healthy eating behaviors among young children., Competing Interests: Declaration of competing interest No competing interests of any authors or persons related to this research are declared., (Copyright © 2024.

Mali national policy recommends that women take iron and folic acid supplements (IFA) from the time of the first antenatal care (ANC) visit, throughout pregnancy and during the first 3 months after delivery. In 2020, the World Health Organization (WHO) updated their ANC guidelines to recommend the United Nations International Multiple Micronutrient Antenatal Preparation (UNIMMAP) formulation of multiple micronutrient supplements (MMS) in the context of rigorous research, including implementation research. In Bamako, Mali, a codesign process was used to tailor antenatal care MMS packaging and counselling materials aimed at optimizing delivery and uptake of and adherence to MMS. This paper presents the codesign process along with the results of a post-intervention qualitative assessment to evaluate the behaviour change intervention. At the conclusion of the intervention, we conducted semistructured qualitative interviews with 24 women who had received the intervention and six pharmacy managers from the six health centres participating in the study. We conducted two focus groups with midwives who had delivered the intervention and two group discussions with family members of women who had received the intervention. Respondent perspectives reveal an easy experience transitioning from previously used IFA. Women and providers concur that the intervention counselling materials and visual aids were instrumental in influencing the perceived benefit and uptake of MMS. Family members play an influential role in pregnant women's decision-making regarding MMS uptake. MMS and the associated implementation strategies developed through the codesign process were found to be a highly acceptable intervention., (© 2024 The Author(s).

Left ventricular hypertrophy (LVH) is often used as an indicator to assess hypertension-mediated organ damage (HMOD), alongside hypertensive retinopathy (HR) and nephropathy. Assessment of HMOD is crucial when making decisions about treatment optimization. Despite longstanding debate over its reliability to detect LVH, it is common practice to perform an electrocardiogram (ECG) instead of directly assessing left ventricular mass with echocardiography. In this study, the presence of LVH was evaluated using both ECG and echocardiography among consecutive patients suspected of therapy-resistant hypertension or secondary hypertension in the outpatient clinic of the Department of Internal Medicine at the Diakonessen Hospital, Utrecht, the Netherlands, between July 15, 2017, and July 31, 2020. The primary endpoints were the specificity and sensitivity of ECG as a diagnostic tool for LVH, with echocardiography serving as the reference method. Among the 329 participants, we identified 70 individuals (21.3%) with true LVH based on echocardiography. The ECG displayed a sensitivity of 47.9% and a specificity of 75.3%. Moreover, the area under the receiver operating characteristics curve was 0.604. In conclusion, ECG demonstrates limited value in identifying LVH. Considering the importance of accurately assessing HMOD for treatment optimization of hypertension, the role of ECG as a diagnostic tool for LVH is, therefore, questionable. Instead, we recommend employing standard echocardiography as a more reliable diagnostic., (© 2024 The Author(s). The Journal of Clinical Hypertension published by Wiley Periodicals LLC.)

Undernutrition and a lack of learning opportunities can jeopardize long-term growth and development among infants in low- and middle-income countries. We conducted a 6-month 2 × 2 cluster-randomized trial to assess the effects of multiple micronutrient-fortified beverages and responsive caregiving interventions among infants 6-18 months in 72 community sectors in southwest Guatemala. We administered baseline and endline assessments of childhood development (Bayley Scales of Infant and Toddler Development) and socioemotional development (Brief Infant Toddler Socio-Emotional Assessment) and measured ferritin and hemoglobin on a subsample. The trial was analyzed using linear mixed models. At the baseline, the mean age (SD) was 13.0 (4.6) months, including 49% males, 32% who were stunted, 55% who were anemic, and 58% who were iron deficient. At the endline ( n = 328/386, 85% retention), there was no synergistic effect on the fortified beverage and responsive caregiving intervention. Compared to the non-fortified beverage group, socioemotional development improved in the fortified beverage group. There were no intervention effects on other measures of child development, hemoglobin, or ferritin. In a setting with high rates of anemia and iron deficiency, a multiple micronutrient-fortified beverage improved infants' socioemotional development.

Translating agricultural productivity into food availability depends on food supply chains. Agricultural policy and research efforts promote increased horticultural crop production and yields, but the ability of low-resource food supply chains to handle increased volumes of perishable crops is not well understood. This study developed and used a discrete event simulation model to assess the impact of increased production of potato, onion, tomato, brinjal (eggplant), and cabbage on vegetable supply chains in Odisha, India. Odisha serves as an exemplar of vegetable supply chain challenges in many low-resource settings. Model results demonstrated that in response to increasing vegetable production 1.25-5x baseline amounts, demand fulfillment at the retail level fluctuated by + 3% to -4% from baseline; in other words, any improvements in vegetable availability for consumers were disproportionately low compared to the magnitude of increased production, and in some cases increased production worsened demand fulfillment. Increasing vegetable production led to disproportionately high rates of postharvest loss: for brinjal, for example, doubling agricultural production led to a 3% increase in demand fulfillment and a 19% increase in supply chain losses. The majority of postharvest losses occurred as vegetables accumulated and expired during wholesale-to-wholesale trade. In order to avoid inadvertently exacerbating postharvest losses, efforts to address food security through agriculture need to ensure that low-resource supply chains can handle increased productivity. Supply chain improvements should consider the constraints of different types of perishable vegetables, and they may need to go beyond structural improvements to include networks of communication and trade., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Background: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) promotes and supports breastfeeding for low-income women and children. A prior review reported negative associations of WIC with breastfeeding outcomes. WIC food package changes in 2009 increased breastfeeding support., Objective: The objectives of this systematic review were to 1) evaluate evidence on WIC participation and breastfeeding outcomes and 2) evaluate breastfeeding outcomes of WIC participants before versus after the 2009 food package., Data Sources: PubMed, Embase®, CINAHL, ERIC, SCOPUS, PsycINFO, and the Cochrane Central Register of Controlled Trials for papers published January 2009 to April 2022., Eligibility Criteria: Included studies compared breastfeeding outcomes (initiation, duration, exclusivity, early introduction of solid foods) of WIC participants with WIC-eligible nonparticipants, or among WIC participants before versus after the 2009 package change., Study Appraisal Methods: Two independent reviewers evaluated each study and assessed risk of bias using EHPHP assessment., Results: From 13 observational studies we found: 1) moderate strength of evidence (SOE) of no difference in initiation associated with WIC participation; 2) insufficient evidence regarding WIC participation and breastfeeding duration or exclusivity; 3) low SOE that the 2009 food package change is associated with greater breastfeeding exclusivity; 4) low SOE that WIC breastfeeding support services are positively associated with initiation and duration., Limitations: Only observational studies, with substantial risk of bias and heterogeneity in outcomes and exposures., Conclusions and Implications of Key Findings: WIC participation is not associated with a difference in breastfeeding initiation compared to WIC-eligible nonparticipants, but the 2009 food package change may have improved breastfeeding exclusivity among WIC participants and receipt of breastfeeding support services may have improved breastfeeding initiation and duration., (Copyright © 2022 The Authors.

Background: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is intended to improve maternal and child health outcomes. In 2009, the WIC food package changed to better align with national nutrition recommendations., Purpose: To determine whether WIC participation was associated with improved maternal, neonatal-birth, and infant-child health outcomes or differences in outcomes by subgroups and WIC enrollment duration., Data Sources: Search (January 2009 to April 2022) included PubMed, Embase, CINAHL, ERIC, Scopus, PsycInfo, and the Cochrane Central Register of Controlled Trials., Study Selection: Included studies had a comparator of WIC-eligible nonparticipants or comparison before and after the 2009 food package change., Data Extraction: Paired team members independently screened articles for inclusion and evaluated risk of bias., Data Synthesis: We identified 20 observational studies. We found: moderate strength of evidence (SOE) that maternal WIC participation during pregnancy is likely associated with lower risk for preterm birth, low birthweight infants, and infant mortality; low SOE that maternal WIC participation may be associated with a lower likelihood of inadequate gestational weight gain, as well as increased well-child visits and childhood immunizations; and low SOE that child WIC participation may be associated with increased childhood immunizations. We found low SOE for differences in some outcomes by race and ethnicity but insufficient evidence for differences by WIC enrollment duration. We found insufficient evidence related to maternal morbidity and mortality outcomes., Limitation: Data are from observational studies with high potential for selection bias related to the choice to participate in WIC, and participation status was self-reported in most studies., Conclusion: Participation in WIC was likely associated with improved birth outcomes and lower infant mortality, and also may be associated with increased child preventive service receipt., Primary Funding Source: Agency for Healthcare Research and Quality.

Background: Anemia is a global public health problem that undermines childhood development. India provides government-sponsored integrated nutrition/child development preschools., Objectives: This double-masked, cluster-randomized controlled trial examines whether point-of-use multiple micronutrient powder (MNP) compared with placebo fortification of preschool meals impacts child development and whether effects vary by preschool quality (primary outcome) and biomarkers of anemia and micronutrients (secondary outcomes). We also measured growth and morbidity., Methods: We randomly assigned 22 preschools in rural India to receive MNP/placebo fortification. We administered baseline and endline blood sampling and measures of childhood development (Mullen Scales of Early Learning, inhibitory control, social-emotional), anthropometry, and morbidity to preschoolers (aged 29-49 mo). Preschools added MNP/placebo to meals 6 d/wk for 8 mo. We conducted linear mixed-effects regression models accounting for preschool clustering and repeated measures. We evaluated child development, examining effects in high- compared with low-quality preschools using the Early Childhood Environment Rating Scale-Revised and the Home Observation for the Measurement of the Environment Inventory, modified for preschools., Results: At baseline, mean age ± SD was 36.6 ± 5.7 mo, with 47.8% anemic, 41.9% stunted, and 20.0% wasted. Baseline expressive/receptive language scores were higher in high-quality compared with low-quality preschools (P = 0.02 and P = 0.03, respectively). At endline (91% retention, n = 293/321), we found MNP compared with placebo effects in expressive language (Cohen's standardized effect d = 0.4), inhibitory control (d = 0.2), and social-emotional (d = 0.3) in low-quality, not high-quality, preschools. MNP had significantly greater reduction of anemia and iron deficiency compared with placebo (37% compared with 13.5% and 41% compared with 1.2%, respectively). There were no effects on growth or morbidity., Conclusions: Providing multiple micronutrient-fortified meals in government-sponsored preschools is feasible; reduced anemia and iron deficiency; and, in low-quality preschools, increased preschoolers' expressive language and inhibitory control and reduced developmental disparities. Improving overall preschool quality by incorporating multiple components of nurturing care (responsive care, learning, and nutrition) may be necessary to enhance preschoolers' development.

Background: Growth failure in sub-Saharan Africa leads to a high prevalence of child stunting starting in infancy, and is attributed to dietary inadequacy, poor hygiene, and morbidity., Objectives: To evaluate the impact of a program in Malawi providing a lipid-based nutrient supplement to infants from 6-23 months of age, accompanied by a social and behavior change communication intervention to optimize caregiver feeding and handwashing practices., Methods: This impact evaluation was a quasi-experimental, longitudinal study with 1 program and 1 comparison district. Infants were enrolled at 6-7 months of age. Anthropometry, child morbidity, and caregiver feeding and handwashing practices were assessed at enrollment and at 6, 12, and 18 month follow-ups (ages 6, 12, 18, and 24 months, respectively). Changes in the length-for-age z-score (LAZ), weight-for-length z-score (WLZ), and midupper arm circumference (MUAC) were compared using mixed-effects models. Program impacts on child stunting (LAZ < -2), wasting (WLZ < -2), morbidity, and feeding and handwashing practices were estimated using difference-in-differences., Results: We enrolled 367 infants across the program (n = 176) and comparison (n = 191) districts. The combined prevalences of stunting and wasting at enrollment were 42.1% and 1.4%, respectively, and did not differ by district. At enrollment, the prevalence of severe stunting (LAZ < -3) was higher in the program (15.5%) versus comparison (7.6%) district (P = 0.02), with corresponding lower LAZ scores (-1.9 vs. -1.7, respectively; P = 0.12). Growth velocities favored program children, such that LAZ, WLZ, and MUAC measurements increased by +0.12/y (P = 0.06), +0.12/y (P = 0.04), and +0.24 cm/y (P < 0.001), respectively, leading to comparable LAZ distributions across districts by 24 months of age. Program exposure was associated with 19.8 percentage point (pp) and 13.8 pp reductions in the prevalences of malaria (P = 0.001) and fever (P = 0.02), respectively, at the 18-month follow-up. Improvements of 20 pp (P < 0.01) in minimum dietary diversity and minimum acceptable diet were seen in the program versus comparison district at 18 months of follow-up., Conclusions: The program improved child growth patterns, with benefits to health and diet apparent after 18 months of exposure. This trial was registered at clinicaltrials.gov as NCT02985359., (© The Author(s) 2021. Published by Oxford University Press on behalf of the American Society for Nutrition.)

Prenatal micronutrient supplements are cost-effective in reducing nutritional deficiencies and adverse pregnancy and birth outcomes. However, poor adherence remains a potential barrier to the successful implementation of these supplementation programs. This systematic review assessed the effectiveness of interventions designed to increase adherence to prenatal micronutrient supplementation. Following the Cochrane Collaboration Methodology, literature searches were conducted in six electronic databases and gray literature (on July 24, 2020), and abstract screening, data extraction, and risk of bias assessment were conducted independently by two reviewers. We included 22 studies. Interventions that resulted in increased adherence were most of the education-based strategies, consumption monitoring by volunteer health workers or family members, SMS reminders, free provision of supplements, a multicomponent intervention with community mobilization, and a participatory action research intervention. In several studies, increased adherence was accompanied by beneficial effects on pregnancy and birth outcomes. Given the heterogeneity of study designs and methods used to define and measure adherence, a meta-analysis was not appropriate. We identified several potentially effective strategies to improve supplementation adherence, which may need to be adapted to specific contexts when considered for program implementation. However, additional high-quality studies are critically needed to effectively guide policies and programs., (© 2021 The Authors.

Rapid weight gain increases risks of obesity and associated co-morbidities. The objective was to reduce the rate of body mass index (BMI) growth (BMI z score), relative to control. Secondary outcomes were toddler-mother physical activity, mealtime interactions and fruit/vegetable intake. The randomized three-arm, eight-session, 4-month trial, conducted 2009-2013, included two intervention arms (responsive parenting and maternal lifestyle) and an attention control (home safety). Baseline and 6- and 12-month follow-up evaluations included weight and length/height, ankle accelerometry, video-recorded mealtime interactions (Emotional Availability Scales) and 24-h diet recalls (Healthy Eating Index-2015 [HEI-2015]). Analyses used linear mixed-effects models with repeated measures comparing intervention versus control changes in BMI z score. We recruited 277 racially mixed (70% African American) toddler-mother dyads (mean ages 20.1 months and 27.3 years) from US WIC and primary care clinics and randomized them into intervention versus control; 31% toddlers and 73% mothers were overweight/obese. At follow-up, changes in the rate of toddler BMI z score and maternal BMI were non-significant. Maternal lifestyle group toddlers and mothers spent 24.43 and 11.01 more minutes in physical activity (95% confidence interval [CI]: 2.55, 46.32, and 95% CI: 1.48, 20.54, respectively). Fruit intake increased in both intervention groups. Hostile mealtime interactions increased in the maternal lifestyle group, and in supplementary analyses, mealtime interactions were significantly higher in the responsive parenting group than in the maternal lifestyles group, suggesting that toddler dietary interventions include responsive parenting. Intervention effects were stronger among older versus younger toddlers. Despite no impact on weight gain, additional research should examine integrated two-generation responsive parenting and maternal lifestyle interventions among toddler-mother dyads., (© 2020 The Authors.

Background: The prevalence of stunting in central rural Malawi is ∼50%, which prompted a multipronged nutrition program in 1 district from 2014 to 2016. The program distributed a daily, fortified, small-quantity lipid-based nutritional supplement, providing 110 kcal and 2.6 g of protein to children aged 6-23 mo, and behavior change messages around optimal infant and young child feeding (IYCF) and water, sanitation, and hygiene., Objectives: Our objective was to perform an impact evaluation of the program using a neighboring district as comparison., Methods: Using a quasi-experimental study design, with cross-sectional baseline (January-March, 2014; n = 2404) and endline (January-March, 2017; n = 2453) surveys, we evaluated the program's impact using a neighboring district as comparison. Impact on stunting was estimated using propensity score weighted difference-in-differences regression analyses to account for baseline differences between districts., Results: No differences in mean length-for-age z-score or prevalence of stunting were found at endline. However, mean weight, weight-for-length z-score, and mid-upper arm circumference were higher at endline by 150 g, 0.22, and 0.19 cm, respectively, in the program compared with the comparison district (all P < 0.05). Weekly reports of high fever and malaria were also lower by 6.4 and 4.7 percentage points, respectively, in the program compared with the comparison district (both P < 0.05). There was no impact on anemia. Children's dietary diversity score improved by 0.17, and caregivers' infant and young child feeding and hand-washing practices improved by 8-11% in the program compared with the comparison district (all P < 0.05)., Conclusions: An impact evaluation of a comprehensive nutrition program in rural Malawi demonstrated benefit for child ponderal growth and health, improved maternal IYCF and hand-washing practices, but a reduction in stunting prevalence was not observed., (Copyright © The Author(s) on behalf of the American Society for Nutrition 2020.)

We evaluated the association between maternal anxiety score and diet quality over time among mothers and toddlers in low-income families. Longitudinal data were collected from 267 mother-toddler dyads in an obesity prevention trial. Participants were recruited from the Special Supplemental Nutrition Program for Women, Infants and Children and paediatric clinics between 2007 and 2010. Dyads were assessed at study enrolment (Time 1), 6-month (Time 2), and 12-month follow-up (Time 3). On the basis of a 1-day 24-hr dietary recall, we estimated maternal and toddler diet quality using the Healthy Eating Index 2015. Anxiety, a time-varying variable, was assessed via the State-Trait Anxiety Inventory. Associations between maternal anxiety score and maternal and toddler diet quality over time were assessed in adjusted mixed models. Maternal and toddler diet quality were positively correlated (r = .48, p < .001). Higher maternal anxiety scores were related to lower toddler Healthy Eating Index scores (b = -0.51, 95% confidence interval, CI [-0.87, -0.15]) with no significant variation over time. The relation between maternal diet quality and anxiety score varied over time (b = 0.28, p = .03, for time-anxiety interaction). Higher maternal anxiety scores were associated with lower maternal diet quality at Time 1 (b = -0.71, 95% CI [-1.09, 0.34]) and at Time 2 (b = -0.51, 95% CI [-0.97, -0.05]), but not at Time 3 (b = -0.14, 95% CI [-0.54, 0.26]). Findings suggest that mothers and toddlers exhibited similar low-quality dietary patterns and that lower diet quality was associated with higher maternal anxiety scores. Approaches to enhance diet quality may consider incorporating anxiety-reducing strategies into maternal and toddler care and feeding behaviour guidelines., (© 2020 The Authors.

Background: Nutrient-level intakes from home-prepared complementary foods are rarely estimated among infants and young children in low-income settings. The major constraints are related to lack of standard recipes and ingredients and portion sizes., Objectives: This article describes the feasibility, applicability, and validity of a post hoc qualitative methodology to estimate nutrient intakes in children using 24-h dietary recall., Methods: Semistructured, interviewer-administered caregiver 24-h diet recalls were conducted to assess food intake among children participating in a randomized trial of complementary food supplementation at ages 6, 9, 12, 15, 18, and 24 mo in rural Bangladesh. At the end of the diet data collection, focus group discussions with mothers ( n  = 6) and cooking activities ( n  = 5) were conducted to obtain standard recipes (and ingredients) and portion sizes for reported foods given at different ages. Nutrient intakes were calculated for children in the control group ( n  = 1438), and convergent validity of the data was tested by examining the association of energy and protein intakes with child age and socioeconomic status (SES)., Results: Focus group discussions generated standardized recipes for 21 commonly consumed mixed dishes being fed to children. These recipes were cooked, and portion sizes of standardized measures used in 24-h recalls were quantified in grams. For discrete foods, we quantified women's perceptions of "small," "medium," and "large" in grams. Across all ages, food groups consumed consisted mostly of staples, with the most common being rice, potatoes, and biscuits. Using portion size data and recipe ingredients, the 24-h dietary data, and Bangladeshi food composition tables, we successfully estimated nutrient intakes in children. Convergent validity analysis showed that energy and protein intakes were strongly associated with age and SES (both P  < 0.001)., Conclusions: We demonstrated the use of a validated, qualitative methodology for estimating nutrient intakes in young children from complementary foods in undernourished contexts. This trial was registered at clinicaltrials.gov as NCT01562379., (Copyright © The Author(s) on behalf of the American Society for Nutrition 2020.)

Micronutrient supplementation during pregnancy has been shown to be a cost-effective method to reduce the risk of adverse pregnancy and birth outcomes. However, one of the main barriers to the successful implementation of a micronutrient supplementation program in pregnancy is poor adherence. Our review will assess the effectiveness of interventions designed to increase adherence to micronutrient supplements in pregnancy. Following the Cochrane Collaboration Methodology, we will start by conducting the literature searches on Medline (via PubMed), Embase, Scopus, Web of Science, and Cochrane Library, in addition to sources of gray literature, to retrieve all the available relevant studies. We will include randomized controlled trials and nonrandomized studies with a control group, where participants are pregnant women taking any micronutrient supplements in the context of antenatal care globally. We will include studies with targeted interventions designed to improve adherence to micronutrient supplementation in pregnant women compared with (1) usual care or no intervention or (2) other targeted micronutrient adherence intervention. Abstract selection, data extraction, and risk of bias assessment (according to the type of studies) will be conducted by two independent reviewers. The pooled results will be reported using the standardized mean differences for continuous data, and odds ratio or risk ratio for dichotomous data. We will assess sources of heterogeneity and publication bias. By following this protocol, we will systematically assess and synthesize the existing evidence about interventions designed to increase adherence to micronutrient supplementation in pregnant women. Understanding which strategies are more effective to increase the consumption of micronutrient supplements during this critical stage of life will have significant implications for clinicians and policymakers involved in the delivery of prenatal micronutrient supplementation interventions., (© 2020 The Authors.

One in four children younger than age five in Guatemala experiences anaemia (haemoglobin <11.0 g/dl). This study characterized the factors and micronutrient deficiencies associated with anaemia in a baseline cross-sectional sample of 182 Guatemalan infants/toddlers and 207 preschoolers, using generalized linear mixed models. Associations between anaemia and maternal, child and household variables, and biomarkers (soluble transferrin receptor, ferritin, zinc, folate, vitamin B12, C-reactive protein, and α1-acid glycoprotein) were explored. Rates of anaemia were 56% among infants/toddlers and 12.1% among preschoolers. In children with anaemia, rates of iron deficiency (low ferritin based on inflammation status, and/or high soluble transferrin receptor, ≥1.97 mg/L) and zinc deficiency (serum zinc <65 μg/dl) were 81.1% and 53.7%, respectively. Folate deficiency (either plasma folate <3 ng/ml or erythrocyte folate <100 ng/ml) was 3.3%. Vitamin B12 deficiency (plasma vitamin B12 <148 pmol/L) was 7.5%. For infants and toddlers (<24 months), the odds ratio of anaemia was lower when higher number of adults lived in the household (OR = 0.69; 95% CI [0.53, 0.90]), and higher when children were zinc deficient (OR = 3.40; 95% CI [1.54, 7.47]). For preschoolers (36-60 months), the odds ratio of anaemia was lower for every additional month of age (OR = 0.90; 95% CI [0.81, 1.00]). Findings suggest that micronutrient deficiencies coexist in Guatemalan rural children, and zinc deficiency is associated with anaemia in children <24 months, highlighting the need of continued multidisciplinary interventions with multiple micronutrients. Further research examining how household composition, feeding practices, and accessibility to micronutrient supplements and to animal source foods is needed to incorporate strategies to improve the nutritional status of Guatemalan children., (© 2019 The Authors.

Background: Global attention to the study of nutrition program implementation has been inadequate yet is critical for effective delivery and impact at scale., Objectives: The objective of this mixed-methods process evaluation study was to measure the recruitment, fidelity, and reach of a large-scale, community-based nutrition program in Malawi., Methods: The nutrition program delivered a small-quantity lipid-based nutrient supplement (SQ-LNS) and social and behavior change communication (SBCC) to improve infant and young child feeding (IYCF) and water, sanitation, and hygiene (WASH) practices in households with children aged 6-23 mo. Program monitoring and evaluation data were used to measure program recruitment, reach, and fidelity. Structured direct observations and knowledge questionnaires with program volunteers measured quality aspects of program fidelity. The number of times activities were done correctly was used to tabulate proportions used to represent program functioning., Results: Half (49.5%) of eligible children redeemed program benefits by 8 mo of age during the first 4 y of program implementation. Implementation of training activities for SBCC cadres exceeded program targets (100.6%), but the completion of certain modules (breastfeeding and complementary feeding) was lower (22.9% and 18.6%, respectively). Knowledge of IYCF, WASH, and SQ-LNS messages by volunteers was >85% for most messages, except ability to list the 6 food groups (35.7%). Structured direct observations of SQ-LNS distributions indicated high fidelity to program design, whereas those of household-level counseling sessions revealed lack of age-appropriate messaging. Program reach showed participation in monthly distribution sessions of 81.0%, group counseling of 93.3%, and individual-level counseling of 36.9%., Conclusions: This community-based nutrition program was implemented with high fidelity and quality, with specific interventions requiring further attention. The documentation of implementation contributes to our understanding about how program impacts were achieved., (Copyright © The Author(s) 2019.)

Stunting has been negatively associated with children's development. We examined the range of height by testing hypotheses: (a) height is positively associated with children's development, with associations moderated by inflammation and (b) home environments characterized by nurturance and early learning opportunities is positively associated with children's development over time and attenuate associations with height. Data included 513 infants (mean age 8.6 months) and 316 preschoolers (mean age 36.6 months) in rural India from a randomized controlled trial of multiple micronutrient powders (MNPs). Measures included height (height-for-age z-scores based on WHO standards), inflammation (C-reactive protein concentration >5 mg/L), nurturance (HOME Inventory), child development (Mullens Scales of Early Learning), and inhibitory control (preschoolers). Linear mixed effects models accounting for repeated measures, clustering, and confounders were used to assess associations between height and child development over time (infants: enrollment, 6 and 12 months; preschoolers: enrollment and 8 months). Moderating effects of inflammation and nurturance were tested with interaction terms. Among infants and preschoolers, height and nurturance were positively associated with all domains of child development over time, with the exception of inhibitory control. Among preschoolers, in the presence of inflammation, height was not associated with child development. Among infants, but not preschoolers, a nurturant home environment attenuated significant associations between height with fine motor and receptive language development. The mechanisms associated with children's development over time are multifactorial and include direct and indirect associations among nutrition, health, and the home environment, as supported by the Nurturing Care Framework., (© 2019 John Wiley & Sons Ltd.)

Objective: Excess gestational weight gain (GWG) in obese women is linked to adverse maternal outcomes and is particularly pervasive among African Americans, who have the highest obesity rates in the USA. A better understanding of culturally relevant attitudes and perceptions of GWG is needed to develop targeted interventions to prevent excess GWG among this group., Design: Using the constructs of Social Cognitive Theory, we explored attitudes and perceptions surrounding diet and exercise among low-income obese African-American pregnant women in Baltimore. We conducted twenty-one semi-structured in-depth interviews with pregnant adult women., Setting: Participants were recruited from a referral clinic for obese pregnant women at a large urban hospital in Baltimore, MD, USA., Participants: Twenty-one low-income African-American adult females in the first two trimesters of pregnancy with BMI &gt; 30·0 kg/m2., Results: Lack of knowledge was not the main obstacle to healthy behaviours during pregnancy. Rather, food cravings and fatigue, an unhealthy physical food environment, limited self-efficacy for controlling excessive GWG, and a lack of adequate emotional and informational support impacted women's agency. While digital technology was discussed as a vehicle to promote maintenance of a healthy weight in pregnancy, further research is needed to test how it can be used to empower women to engage in healthy behaviours during pregnancy., Conclusion: Interventions to prevent excess GWG among African-American pregnant women should harness support from partners and family and must go beyond sharing of clinical knowledge to also include strategies that improve the food environment, diet quality and self-efficacy.

Child stunting is a public health problem in Malawi. In 2014, the Government of Malawi launched the Right Foods at the Right Time (RFRT) program in Ntchisi district delivering nutrition social and behavior change communication, a small-quantity lipid-based nutrient supplement to children 6-23 months, and nutrition sensitive activities. Monitoring and evaluation (M&E) systems are key aspects of successful program implementation. We describe these and the methodology for an impact evaluation that was conducted for this program. Two monitoring systems using traditional and electronic platforms were established to register and track program delivery and processes including number of eligible beneficiaries, worker performance, program participation, and to monitor input, output, and outcome indicators. The impact evaluation used comparative cross-sectional and longitudinal designs to assess impact on anthropometric and infant and young child feeding outcomes. Three cross-sectional surveys (base-, mid-, and end-line) and two longitudinal cohorts of children followed in 6-month intervals from 6 to 24 months of age, were conducted in sampled households in the program and a neighboring comparison district. Additional M&E included qualitative studies, a process evaluation, and a cost-effectiveness study. The current paper describes lessons from this program's M&E, and demonstrates how multiple implementation research activities can inform course-correction and program scale-up., (Copyright © 2018 The Authors.

Objective: To examine the association between household food insecurity and dietary diversity in the past 24h (dietary diversity score (DDS, range: 0-9); minimum dietary diversity (MDD, consumption of three or more food groups); consumption of nine separate food groups) among pregnant and lactating women in rural Malawi., Design: Cross-sectional study., Setting: Two rural districts in Central Malawi., Subjects: Pregnant (n 589) and lactating (n 641) women., Results: Of surveyed pregnant and lactating women, 66·7 and 68·6 %, respectively, experienced moderate or severe food insecurity and only 32·4 and 28·1 %, respectively, met MDD. Compared with food-secure pregnant women, those who reported severe food insecurity had a 0·36 lower DDS (P&lt;0·05) and more than threefold higher risk (OR; 95 % CI) of not consuming meat/fish (3·19; CI 1·68, 6·03). The risk of not consuming eggs (3·77; 1·04, 13·7) was higher among moderately food-insecure pregnant women. Compared with food-secure lactating women, those who reported mild, moderate and severe food insecurity showed a 0·36, 0·44 and 0·62 lower DDS, respectively (all P&lt;0·05). The risk of not achieving MDD was higher among moderately (1·95; 1·06, 3·59) and severely (2·82; 1·53, 5·22) food-insecure lactating women. The risk of not consuming meat/fish and eggs increased in a dose-response manner among lactating women experiencing mild (1·75; 1·01, 3·03 and 2·81; 1·09, 7·25), moderate (2·66; 1·47, 4·82 and 3·75; 1·40, 10·0) and severe (5·33; 2·63, 10·8 and 3·47; 1·19, 10·1) food insecurity., Conclusions: Addressing food insecurity during and after pregnancy needs to be considered when designing nutrition programmes aiming to increase dietary diversity in rural Malawi.

Background: Adolescents' dietary intake often fails to meet national dietary guidelines, especially among low-income African-American youth. The dietary habits established in adolescence are likely to continue into adulthood, and a poor-quality diet increases the risk of developing obesity and chronic disease. Based on principles from ecological and social-cognitive behavior change health theories, perceptions of parental beliefs about healthy eating, perceptions of peer eating behaviors, and parental monitoring of what adolescents eat may positively influence adolescent diet quality., Objective: The purposes of this study were to determine whether perceived parental beliefs about nutrition, perceived peer eating behaviors, and reported parental monitoring of the adolescent diet were related to African-American adolescent diet quality and whether these relationships were moderated by adolescent age or sex., Design: This secondary cross-sectional study used baseline data (2002 to 2004) from an urban community sample of low-income adolescents participating in a health promotion trial., Participants/setting: Participants were 216 African-American adolescent-caregiver dyads in Baltimore, MD., Main Outcome Measures: The 2010 Healthy Eating Index was used to estimate adolescent diet quality., Statistical Analyses Performed: Analyses included correlations, t tests, age- and sex-by-perception regression interactions, and multivariate regressions adjusted for body mass index-for-age percentile, caregiver weight status, and caregiver depressive symptoms., Results: Higher diet quality scores were related to higher levels of perceived parental and peer support for healthy eating behaviors among adolescents (β=.21; P<0.05; β=.15; P<0.05, respectively) and to caregiver reports of parental monitoring of adolescent dietary behavior (β=1.38, P<0.01). Findings were not moderated by age or sex., Conclusions: Consistent with ecological and social-cognitive theories, adolescents look to their friends and family in making healthy food choices. The relationships uncovered by this study describe some of the contextual, interpersonal influences associated with diet quality among low-income, urban African-American adolescents and warrant further exploration in future intervention studies., (Copyright © 2018 Academy of Nutrition and Dietetics.

Background: Inadequate complementary feeding is common in low- and middle-income countries, contributing to growth deficits. Complementary food supplements (CFSs) aim to fill dietary gaps, but few CFS studies have measured nutrient intake. In a community-based, randomized CFS trial in Bangladesh, we previously reported poor dietary diversity in 6-18-mo-old participants., Objective: We investigated, in a secondary analysis in the same trial, micronutrient intake adequacy in supplemented compared with control-arm children., Methods: At age 6 mo, children were assigned to 1 y of child-feeding counseling for mothers (control) or counseling plus 1 of 4 CFS formulations. Mothers were administered quantitative past 24-h diet questionnaires for their children at ages 6, 9, 12, 15, and 18 mo. Nutrient intakes were estimated with local recipes and food composition tables assuming average age-specific breastmilk intake. Adequacy was evaluated relative to estimated average requirements or adequate intakes. Multivariate analysis of variance and generalized estimating equation (GEE) regression models estimated the effect of each CFS on nutrient adequacy. GEE models tested dietary predictors of nutrient adequacy in the control arm., Results: A total of 25,964 dietary modules across 5 interviews were completed. Nutrient adequacy from home foods combined with assumed breastmilk intake was low. Only 5 of 16 micronutrients were adequately consumed by >60% of children at 18 mo of age. Daily CFSs did not affect energy-adjusted micronutrient intake from home foods at any follow-up age (P > 0.05). CFSs increased the mean adequacy ratio for all micronutrients (P < 0.001 at all ages), to ≥1 for 14 of 16 micronutrients at 18 mo. Dietary diversity predicted adequate iron, zinc and calcium intake at 15 mo in unsupplemented controls., Conclusions: Home foods did not meet the estimated micronutrient needs of 9-18-mo-old children in rural Bangladesh. Daily supplementation with fortified complementary foods filled many micronutrient intake gaps and did not displace home foods. Previously, CFSs were shown to also improve linear growth and reduce stunting in this cohort. Findings support the need for CFSs in similar settings to promote nutritional well being and growth. This trial was registered at clinicaltrials.gov as NCT01562379.

Objective: Overall diet patterns may be a better predictor of disease risk than specific nutrients or individual foods. The purpose of this study is to examine how overall diet patterns relate to nutritional intake, body composition, and physiological measures of chronic disease risk among low-income, urban African American adolescents., Methods: Cross-sectional data were collected from two samples of African American adolescents (n = 317) from a low-income urban community, including dietary intake using the food frequency Youth/Adolescent Questionnaire and anthropometric measures. Serum cholesterol, serum lipoproteins, and glucose tolerance were measured in a subsample. Means testing compared differences in Healthy Eating Index (HEI) and Healthy Eating Index-2010 (HEI-2010) component and total scores. Pearson correlations examined how HEI and HEI-2010 scores related to nutrient, food intakes, and markers of disease risk, including body mass index, percent body fat, abdominal fat, serum cholesterol, serum lipoproteins, and impaired glucose tolerance. Fisher R-Z transformations compared magnitude differences between HEI and HEI-2010 correlations to nutritional intake and chronic disease risk., Results: Both HEI and HEI-2010 scores were positively associated with micronutrient intakes. Higher HEI scores were inversely related to serum cholesterol, low-density lipoprotein, impaired glucose tolerance, percent body fat, and percent abdominal fat. HEI-2010 scores were not related to biomarkers of chronic disease risk., Conclusions: Compared to the HEI-2010, the HEI is a better indicator of chronic disease risk among low-income, urban African American adolescents.

The double burden of malnutrition, defined by the coexistence of undernutrition and overweight, is well documented in low- and middle-income countries. However, the mechanisms by which employment may be related to maternal and child weight status in low- and middle-income countries are not well understood. We conducted in-depth interviews among 20 mothers who participated in Project MIEL, a contemporary trial which evaluated the effects of an integrated micronutrient supplement and parenting intervention in rural Guatemala. We utilized semi-structured interviews to explore the pathways by which maternal employment might influence bodyweight. Interviews were structured to explore the factors that mothers considered when deciding whether or not to participate in the labor force and how mothers perceived the influence of employment on determinants of their own bodyweight and that of their children. Themes were used to develop a conceptual framework. Mothers described four pathways through which employment could lead to changes in weight status: changes in food purchasing; improved household well-being; changes in time allocation; and psychological effects. Mothers described purchasing increased quantities and more varied types of food, as well as the purchase of energy-dense foods. Less time to devote to food preparation resulted in mothers preparing quicker meals and relying on substitute childcare. Mothers also expressed feelings of worry and neglect in relation to being employed, and perceived that these feelings would affect weight. A better understanding of these mechanisms is important for developing policies and programs to support women in the workplace and also reducing maternal and child overweight in Guatemala., (© 2017 John Wiley & Sons Ltd.)

This study aimed to assess the factors associated with home meal preparation (HMP) and fast-food sources use (FFS) frequencies of low-income African-American adults and their healthy food beliefs and attitudes, food-related psychosocial factors, food acquisition patterns, food sources use, and BMI. We used cross-sectional data from 295 adults living in Baltimore, USA. HMP was inversely associated with FFS, which had lower odds of HMP ≥1 time/day and higher BMI scores. HMP was positively associated with positive beliefs and self-efficacy toward healthy foods, getting food from healthier food sources, and lower FFS. Higher odds of HMP ≥1 time/day were associated with getting food from farmers' market and supermarkets or grocery stores. FFS had an inverse association with positive beliefs and self-efficacy toward healthy foods, and a positive association with less healthy food acquisition scores. Higher odds of FFS ≥1 time/week were associated with getting food from corner stores, sit-down restaurants, and convenience stores.

Objective: To determine whether living in a food swamp (≥4 corner stores within 0·40 km (0·25 miles) of home) or a food desert (generally, no supermarket or access to healthy foods) is associated with consumption of snacks/desserts or fruits/vegetables, and if neighbourhood-level socio-economic status (SES) confounds relationships., Design: Cross-sectional. Assessments included diet (Youth/Adolescent FFQ, skewed dietary variables normalized) and measured height/weight (BMI-for-age percentiles/Z-scores calculated). A geographic information system geocoded home addresses and mapped food deserts/food swamps. Associations examined using multiple linear regression (MLR) models adjusting for age and BMI-for-age Z-score., Setting: Baltimore City, MD, USA., Subjects: Early adolescent girls (6th/7th grade, n 634; mean age 12·1 years; 90·7 % African American; 52·4 % overweight/obese), recruited from twenty-two urban, low-income schools., Results: Girls' consumption of fruit, vegetables and snacks/desserts: 1·2, 1·7 and 3·4 servings/d, respectively. Girls' food environment: 10·4 % food desert only, 19·1 % food swamp only, 16·1 % both food desert/swamp and 54·4 % neither food desert/swamp. Average median neighbourhood-level household income: $US 35 298. In MLR models, girls living in both food deserts/swamps consumed additional servings of snacks/desserts v. girls living in neither (β=0·13, P=0·029; 3·8 v. 3·2 servings/d). Specifically, girls living in food swamps consumed more snacks/desserts than girls who did not (β=0·16, P=0·003; 3·7 v. 3·1 servings/d), with no confounding effect of neighbourhood-level SES. No associations were identified with food deserts or consumption of fruits/vegetables., Conclusions: Early adolescent girls living in food swamps consumed more snacks/desserts than girls not living in food swamps. Dietary interventions should consider the built environment/food access when addressing adolescent dietary behaviours.

Postpartum, low-income mothers are at risk for mental health symptoms and obesity, and disordered eating attitudes may be associated with both mental health and obesity in this vulnerable population. The study objective is to determine whether higher levels of mental health symptoms are associated with increased odds of emotional and restrained eating attitudes in this sample of Special Supplemental Nutrition Program for Women, Infants and Children (WIC) participants. Data on 711 mothers of infants <13 months from a statewide sample of Maryland WIC participants were collected via telephone survey. Maternal mental health symptoms were measured on continuous scales for depression (PRIME-MD), stress (Perceived Stress Scale) and anxiety (Spielberger State-Trait Anxiety Inventory). Emotional and restrained eating attitudes were measured with questions adapted from the Dutch Eating Behavior Questionnaire. Multivariate logistic regression analysis was used. Obesity [body mass index (BMI) ≥ 30] was explored as a moderating variable. Mothers reporting higher levels of depression symptoms [odds ratio (OR) = 3.93, 95%CI: 2.71-5.69], anxiety symptoms (OR = 1.96, 95%CI: 1.47-2.65), stress symptoms (OR = 2.09, 95%CI: 1.67-2.61) and high overall mental health symptomatology (OR = 3.51, 95%CI: 2.43-5.3) had increased odds of emotional eating attitudes. There were significant associations between symptoms of depression (OR = 1.59, 95% CI: 1.12-2.25) and increased odds of restrained eating attitudes. Obesity did not moderate the association. Mothers with mental health symptoms are at risk for disordered eating attitudes, which may increase risk of poor diet. These findings underscore the need for greater focus on addressing maternal mental health status and eating attitudes in the postpartum period., (© 2016 John Wiley & Sons Ltd.)

Responsive feeding is a derivative of responsive parenting that has been applied to infant and young child feeding. With a theoretical basis in the reciprocal interactions between parents and children, responsive feeding is particularly relevant during complementary feeding as young children progress from an exclusively milk-based liquid diet to the family diet and self-feeding. The period of complementary feeding includes multiple developmental changes that may threaten a successful transition and lead to growth and feeding problems. In spite of high rates of global childhood underweight, stunting, overweight, and obesity, and the inclusion of responsive feeding in the World Health Organization's Global Strategy for Infant and Young Child Feeding, there have been few intervention trials of responsive feeding. The aim of this chapter is to examine how parents and young children navigate the progression in feeding, with an emphasis on complementary feeding, and to address the following topics: (1) navigating the progression of feeding development, (2) provision of responsive feeding, (3) preventing or resolving growth and feeding problems, (4) responsive feeding research, and (5) strategies to promote healthy mealtime interactions. To advance responsive feeding research and practice, clarity is needed in both measurement and intervention strategies, guided by the reciprocity between parent and child interactions inherent in the theoretical basis of responsive feeding., (© 2017 Nestec Ltd., Vevey/S.

Background: Complementary food supplements (CFSs) can enhance growth where stunting is common, but substitution for the usual diet may reduce observed benefits., Objective: We aimed to characterize dietary diversity from home foods in a CFS efficacy trial and determine whether supplementation reduced breastfeeding frequency or displaced home foods., Design: In a cluster-randomized controlled trial in rural Bangladesh, children (n = 5499) received, for 1 y starting at age 6 mo, periodic child feeding counseling for mothers (control) or counseling plus 1 of 4 CFSs fed as a daily snack. Breastfeeding status and past 24-h diet were assessed at enrollment and every 3 mo thereafter until 18 mo of age. A 7-food group dietary diversity score (DDS) was calculated from home foods only, and a DDS ≥4 constituted minimum dietary diversity (MDD)., Results: Most children (97%) were breastfed through 18 mo of age, and 24-h breastfeeding frequency did not differ by supplementation group. Child dietary diversity was low; only 51% of children met the MDD by 18 mo. Rice, potatoes, and biscuits (cookies) were the most frequently consumed foods, whereas the legumes, dairy, eggs, and vitamin A-rich fruit and vegetable food groups were each consumed by <50% of children. The odds of meeting the MDD through the consumption of home foods were equal or greater in the supplemented groups compared with the control group at all ages. High socioeconomic status and any maternal education were associated with increased odds of MDD at age 18 mo, whereas child sex and household food security were not associated with MDD., Conclusions: In a setting where daily complementary food supplementation improved linear growth, there was no evidence that supplementation displaced breastfeeding or home foods, and the supplementation may have improved dietary diversity. Pathways by which supplementation with fortified foods may enhance dietary diversity, such as an improved appetite and increased body size, need elucidation. This trial was registered at clinicaltrials.gov as NCT01562379.

Background: Shortened sleep duration is associated with poor health and obesity among young children. Little is known about relationships among nighttime sleep duration, sleep behaviors, and obesogenic behaviors/obesity among toddlers. This study characterizes sleep behaviors/duration and examines relationships with obesogenic behaviors/obesity among toddlers from low-income families., Methods: Mothers of toddlers (age 12-32 months) were recruited from urban/suburban sites serving low-income families. Mothers provided demographic information and completed the Brief Infant Sleep Questionnaire (BISQ); a 6-item Toddler Sleep Behavior Scale was derived (TSBS-BISQ, higher score reflects more recommended behaviors). Toddler weight/length were measured; obesity defined as ≥95th percentile weight-for-length. Measures of obesogenic behaviors: physical activity [accelerometry, minutes/day in Moderate-to-Vigorous Physical Activity (MVPA)] and diet quality [24-hour recall, Healthy Eating Index 2005 (HEI-2005)]. Bivariate and adjusted multivariable models examined associations between nighttime sleep behaviors/duration and obesogenic behaviors/obesity., Results: Sample included 240 toddlers (mean age = 20.2 months), 55% male, 69% black, 59% urban. Toddlers spent 55.4 minutes/day in MVPA, mean HEI-2005 score was 55.4, 13% were obese. Mean sleep duration was 9.1 hours, with 35% endorsing 5-6 recommended sleep behaviors (TSBS-BISQ). In multivariable models, MVPA was positively related to sleep duration; obese toddlers had a shorter nighttime sleep duration than healthy weight toddlers [odds ratio = 0.69, p = 0.014]. Nighttime sleep duration was associated with high TSBS-BISQ scores, F = 6.1, p = 0.003., Conclusions: Toddlers with a shorter nighttime sleep duration are at higher risk for obesity and inactivity. Interventions to promote healthy sleep behaviors among toddlers from low-income families may improve nighttime sleep duration and reduce obesogenic behaviors/obesity., Competing Interests: Author Disclosure Statement No competing financial interests exist.

Background: Childhood obesity, one of the greatest challenges to public health, disproportionately affects low-income urban minority populations. Fruits and vegetables (FV) are nutrient dense foods that may be inversely associated with excessive weight gain. We aimed to identify the individual characteristic, psychosocial, and household factors influencing FV and fiber consumption in low-income African-American (AA) youth in Baltimore, MD., Methods: Cross-sectional analysis of data collected from 285 low-income AA caregiver-youth (age range: 10-14 y) dyads participating in the baseline evaluation of the B'More Healthy Communities for Kids obesity prevention trial. The Kid's Block FFQ was used to estimate daily intakes of FV (including 100 % fruit juice) and dietary fiber. Questionnaires were used to assess household socio-demographics, caregiver and youth food purchasing and preparation behavior, and youth psychosocial information. Ordered logit regression analyses were conducted to examine psychosocial and food-related behavior associated with FV and dietary fiber intake (quartile of intake) controlling for youth age, sex, BMI percentile, total calorie intake and household income., Results: On average, youth consumed 1.5 ± 1.1 (M ± SD) servings of fruit, 1.8 ± 1.7 serving of vegetables, and 15.3 ± 10.9 g of fiber/day. There were no differences by gender, age or household income. Greater youth's healthy eating intentions and self-efficacy scores were associated with greater odds ratio for higher intake of FV and fiber (Intention: ORfruit 1.22; 95 % CI: 1.06-1.41, ORvegetable 1.31; 1.15-1.51 and ORfiber 1.46; 1.23-1.74, Self-efficacy: ORfruit 1.07; 1.03-1.12, ORvegetable 1.04; 1.01-1.09, ORfiber 1.10; 1.04-1.16). Youth receiving free/low-cost breakfast were more than twice as likely to have higher fiber intake than those who did not receive free breakfast (OR 2.7; 1.10; 6.9). In addition, youth shopping more frequently at supermarkets were more likely to have greater vegetable and fiber intake (OR 1.26; 1.06-1.50; OR 1.28; 1.03-1.58, respectively). Also, youth with parents who shopped more frequently at fast-food stores had 7 % lower odds for higher vegetable intake (95 % CI: 0.88-0.99)., Conclusion: In this study, both, youth and household factors were associated with youth FV and fiber intake, underscoring the need for a multi-level approach to increasing youths' diet quality. These results will inform and shape an effective intervention program for improving youth dietary intakes.

Objective: In India, national databases indicate anaemia prevalence of 80 % among 6-35-month-old children and 58 % among 36-59-month-old children. The present study aimed to characterise anaemia and the associated factors among infants and pre-schoolers living in rural India., Design: Multivariate logistic regression analysis of data collected prior to an intervention trial. Fe-deficiency with anaemia (IDA), Fe deficiency with no anaemia (IDNA) and anaemia without Fe deficiency were defined. Serum ferritin, soluble transferrin receptor (sTfR) and sTfR/log ferritin index were used to indicate Fe status., Setting: Twenty-six villages of Nalgonda district, Telangana, India. Data were collected in community sites. Participants Four hundred and seventy-six infants (aged 6-12 months), 316 pre-schoolers (aged 29-56 months) and their mothers., Results: Prevalence of anaemia among infants and pre-schoolers was 66·4 and 47·8 %, prevalence of IDA was 52·2 and 42·1 %, prevalence of IDNA was 22·2 and 29·8 %, prevalence of anaemia without Fe deficiency was 14·2 and 5·7 %. Among infants, anaemia was positively associated with maternal anaemia (OR=3·31; 95 % CI 2·10, 5·23; P<0·001), and sTfR/log ferritin index (OR=2·21; 95 % CI 1·39, 3·54; P=0·001). Among pre-schoolers, anaemia was positively associated with maternal anaemia (OR=3·77; 95 % CI 1·94, 7·30; P<0·001), sTfR/log ferritin index (OR=5·29; 95 % CI 2·67, 10·50; P<0·001), high C-reactive protein (OR=4·39; 95 % CI 1·91, 10·06, P<0·001) and young age (29-35 months: OR=1·92; 05 % CI 1·18, 3·13, P=0·009)., Conclusions: Anaemia prevalence continues to be high among infants and pre-schoolers in rural India. Based on sTfR/ferritin index, Fe deficiency is a major factor associated with anaemia. Anaemia is also associated with inflammation among pre-schoolers and with maternal anaemia among infants and pre-schoolers, illustrating the importance of understanding the aetiology of anaemia in designing effective control strategies.

Poor nutrition (substandard diet quantity and/or quality resulting in under- or overnutrition) and the lack of early learning opportunities contribute to the loss of developmental potential and life-long health and economic disparities among millions of children aged <5 y. Single-sector interventions representing either early child development (ECD) or nutrition have been linked to positive child development and/or nutritional status, and recommendations currently advocate for the development and testing of integrated interventions. We reviewed the theoretical and practical benefits and challenges of implementing integrated nutrition and ECD interventions along with the evidence for best practice and benefit-cost and concluded that the strong theoretical rationale for integration is more nuanced than the questions that the published empirical evidence have addressed. For example, further research is needed to 1) answer questions related to how integrated messaging influences caregiver characteristics such as well-being, knowledge, and behavior and how these influence early child nutrition and development outcomes; 2) understand population and nutritional contexts in which integrated interventions are beneficial; and 3) explore how varying implementation processes influence the efficacy, uptake, and cost-benefit of integrated nutrition and ECD interventions., (© 2016 American Society for Nutrition.)

This article reviews the central role of nutrition in advancing the maternal, newborn, and child health agenda with a focus on evidence for effective interventions generated using randomized controlled trials in low- and middle-income countries (LMIC). The 1000 days spanning from conception to 2 years of life are a critical period of time when nutritional needs must be ensured; failure to do so can lead to adverse impacts on short-term survival as well as long-term health and development [corrected]. The burden of maternal mortality continues to be high in many under-resourced settings; prenatal calcium supplementation in populations with low intakes can reduce the risk of pre-eclampsia and eclampsia morbidity and mortality and is recommended, and antenatal iron-folic acid use in many countries may reduce anemia, a condition that may be an underlying factor in postpartum hemorrhage. Sufficient evidence exists to promote multiple micronutrient supplementation during pregnancy to reduce fetal growth restriction and low birth weight. Early initiation of breastfeeding (within an hour), exclusive breastfeeding in the first 6 months of life, and vitamin A supplementation in the first few days of life in Asia (but not in Africa) reduce infant mortality. Biannual large-dose vitamin A supplements to children 6-59 months of age and zinc for treatment of diarrhea continue to be important strategies for improving child health and survival. Early nutrition and micronutrient status can influence child development but should be integrated with early responsive learning interventions. Future research is needed that goes beyond the 1000 days to ensure adequate preconceptional nutrition and health, with special emphasis on adolescents who contribute to a large proportion of first births in many LMIC. Thus, we make the case for integrating proven nutrition interventions with those for health in pregnant women, and with those for health and child development in neonates, infants, and young children to help advance the global MNCH agenda., (Copyright © 2015 Elsevier Inc.

The study's objective was to examine the relation between maternal mental health and infant dietary intake. A cross-sectional, population-based telephone survey was employed within a statewide sample of Maryland Special Supplemental Nutrition Program for Women, Infants and Children participants. A 24-h diet recall was performed using the United States Department of Agriculture Automated Multiple-Pass Method. Analyses presented were based on 689 mother-infant pairs. Overall, 36.5% of mothers reported introducing solids to their infants early (<4 months of age), and 40% reported adding cereal to their infant's bottle. Among 0-6-month-old infants, higher infant energy intake was associated with symptoms of maternal stress [β=0.02; confidence interval (CI): 0.01, 0.04], depression (β=0.04; CI: 0.01, 0.06) and overall maternal psychological distress (β=0.02; CI: 0.003, 0.03). With early introduction of solids in the model, the significant associations between infant energy intake and maternal stress and maternal psychological distress became marginal (P's=0.06-0.10). The association between infant energy intake and maternal depression remained significant (β=0.03; CI: 0.01, 0.06). Among 4-6-month-old infants, intakes of breads and cereals were higher among mothers who reported more symptoms of stress (β=0.12; CI: 0.04, 0.23), depression (β=0.19; CI: 0.03, 0.34), anxiety (β=0.15; CI: 0.02, 0.27) and overall psychological distress (β=0.04; CI: 0.01, 0.07). Among 7-12-month-old infants, dietary intake was not related to mental health symptoms. Findings suggest poorer infant feeding practices and higher infant dietary intake during the first 6 months of age in the context of maternal mental health symptoms. Further research is needed to evaluate these effects on child dietary habits and growth patterns over time., (© 2012 Blackwell Publishing Ltd.)

This article describes the development, design, and implementation of an integrated randomized double-masked placebo-controlled trial (Project Grow Smart) that examines how home/preschool fortification with multiple micronutrient powder (MNP) combined with an early child-development intervention affects child development, growth, and micronutrient status among infants and preschoolers in rural India. The 1-year trial has an infant phase (enrollment age: 6-12 months) and a preschool phase (enrollment age: 36-48 months). Infants are individually randomized into one of four groups: placebo, placebo plus early learning, MNP alone, and MNP plus early learning (integrated intervention), conducted through home visits. The preschool phase is a cluster-randomized trial conducted in Anganwadi centers (AWCs), government-run preschools sponsored by the Integrated Child Development System of India. AWCs are randomized into MNP or placebo, with the MNP or placebo mixed into the children's food. The evaluation examines whether the effects of the MNP intervention vary by the quality of the early learning opportunities and communication within the AWCs. Study outcomes include child development, growth, and micronutrient status. Lessons learned during the development, design, and implementation of the integrated trial can be used to guide large-scale policy and programs designed to promote the developmental, educational, and economic potential of children in developing countries., (© 2013 New York Academy of Sciences.)

This paper describes the development and validation of a 27-item caregiver-reported questionnaire on toddler feeding. The development of the Toddler Feeding Behavior Questionnaire was based on a theory of interactive feeding that incorporates caregivers' responses to concerns about their children's dietary intake, appetite, size, and behaviors rather than relying exclusively on caregiver actions. Content validity included review by an expert panel (n = 7) and testing in a pilot sample (n = 105) of low-income mothers of toddlers. Construct validity and reliability were assessed among a second sample of low-income mothers of predominately African-American (70%) toddlers aged 12-32 mo (n = 297) participating in the baseline evaluation of a toddler overweight prevention study. Internal consistency (Cronbach's α: 0.64-0.87) and test-retest (0.57-0.88) reliability were acceptable for most constructs. Exploratory and confirmatory factor analyses revealed 5 theoretically derived constructs of feeding: responsive, forceful/pressuring, restrictive, indulgent, and uninvolved (root mean square error of approximation = 0.047, comparative fit index = 0.90, standardized root mean square residual = 0.06). Statistically significant (P < 0.05) convergent validity results further validated the scale, confirming established relations between feeding behaviors, toddler overweight status, perceived toddler fussiness, and maternal mental health. The Toddler Feeding Behavior Questionnaire adds to the field by providing a brief instrument that can be administered in 5 min to examine how caregiver-reported feeding behaviors relate to toddler health and behavior.

This article examines the association of iron deficiency (ID) and iron deficiency anemia (IDA) with children's development and behavior, with the goal of providing recommendations to prevent the developmental loss associated with these conditions. Children's risk for ID and IDA is particularly high during the second 6 months of life when prenatal stores are depleted. Longitudinal studies from infancy through adolescence and early adulthood suggest that socioemotional development is uniquely vulnerable to ID and IDA, perhaps being associated with shared neural pathways, and the effects of early iron deficiencies may be irreversible. In addition to direct effects on brain function, ID and IDA may also affect child development indirectly through non-responsive mother-child interactions. Maternal ID is a global problem that may contribute to high rates of maternal depression and non-responsive caregiving. Intervention trials illustrate that children benefit from both nutritional intervention and early learning interventions that promote responsive mother-child interactions. Recommendations to reduce the developmental loss associated with ID and IDA are to reduce the incidence of these conditions by efforts to prevent premature birth, delay cord clamping, ensure adequate maternal iron status, provide iron-rich complementary foods, and ensure access to postnatal interventions that promote responsive mother-infant interaction patterns and early learning opportunities for infants., (© 2011 International Life Sciences Institute.)

Objective: To investigate the relationship between maternal depression and child growth in developing countries through a systematic literature review and meta-analysis., Methods: Six databases were searched for studies from developing countries on maternal depression and child growth published up until 2010. Standard meta-analytical methods were followed and pooled odds ratios (ORs) for underweight and stunting in the children of depressed mothers were calculated using random effects models for all studies and for subsets of studies that met strict criteria on study design, exposure to maternal depression and outcome variables. The population attributable risk (PAR) was estimated for selected studies., Findings: Seventeen studies including a total of 13,923 mother and child pairs from 11 countries met inclusion criteria. The children of mothers with depression or depressive symptoms were more likely to be underweight (OR: 1.5; 95% confidence interval, CI: 1.2-1.8) or stunted (OR: 1.4; 95% CI: 1.2-1.7). Subanalysis of three longitudinal studies showed a stronger effect: the OR for underweight was 2.2 (95% CI: 1.5-3.2) and for stunting, 2.0 (95% CI: 1.0-3.9). The PAR for selected studies indicated that if the infant population were entirely unexposed to maternal depressive symptoms 23% to 29% fewer children would be underweight or stunted., Conclusion: Maternal depression was associated with early childhood underweight and stunting. Rigorous prospective studies are needed to identify mechanisms and causes. Early identification, treatment and prevention of maternal depression may help reduce child stunting and underweight in developing countries.

Child overweight/obesity continues to be a serious public health problem in high-income countries. The current review had 3 goals: 1) to summarize the associations between responsive feeding and child weight status in high-income countries; 2) to describe existing responsive feeding measures; and 3) to generate suggestions for future research. Articles were obtained from PubMed and PsycInfo using specified search criteria. The majority (24/31) of articles reported significant associations between nonresponsive feeding and child weight-for-height Z-score, BMI Z-score, overweight/obesity, or adiposity. Most studies identified were conducted exclusively in the United States (n = 22), were cross-sectional (n = 25), and used self-report feeding questionnaires (n = 28). A recent trend exists toward conducting research among younger children (i.e. infants and toddlers) and low-income and/or minority populations. Although current evidence suggests that nonresponsive feeding is associated with child BMI or overweight/obesity, more research is needed to understand causality, the reliability and validity between and within existing feeding measures, and to test the efficacy of responsive feeding interventions in the prevention and treatment of child overweight/obesity in high-income countries.

This study extends the determinants of parenting model to adolescent mothers by examining how adolescent mother-grandmother psychological conflict and perceptions of infant fussiness from birth through age 2 years relate to children's problem behaviors at age 7. Participants were 181 adolescent mother, child, and grandmother triads living in multigenerational households and recruited at delivery. Psychological conflict was characterized by two stable trajectories. In multivariate models that included maternal depression, both psychological conflict and perceptions of infant fussiness predicted externalizing behavior at age 7. Perceptions of infant fussiness, but not psychological conflict, predicted internalizing behavior at age 7.

Dietary variety and exposure to fruits and vegetables in infancy have been associated with nutritional benefits and later acceptance of these foods. The objective of this study was to examine the prevalence of fruit and vegetable commercial baby food consumption and its relation to dietary variety during infancy. A cross-sectional statewide telephone survey of 733 Maryland mothers and infants receiving benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) was conducted between July 2004 and July 2005. A 24-hour dietary recall was examined to assess infant dietary variety. Among infants from birth to age 5 months, 54% had consumed complementary foods in the past 24 hours; 60% received commercial baby foods. Among infants aged 6 to 12 months, 98% had consumed complementary foods in the past 24 hours; 81% received commercial baby foods. In the latter age range, the average daily number of different types of fruits and vegetables consumed was 1.5±1.2, range 0 to 6). In a multivariate model, infants aged 6 to 12 months who received commercial baby foods consumed a greater variety of fruits and vegetables (β=.54, 95% confidence interval 0.26-0.84; P<0.001) than infants who did not, characterized by a diet that was lower in white potatoes (14% vs 22%) and higher in dark-green (6% vs 5%) and deep-yellow (35% vs 10%) vegetables. Commercial baby food is consumed by a majority of WIC infants, although many mothers introduce it before the recommended age of 6 months. Among infants aged 6 to 12 months, commercial baby food is associated with dietary variety in fruits and vegetables. By encouraging consumption of fruits and vegetables after 6 months of age, either through the provision of commercial baby foods and/or education and resources related to the preparation of fruits and vegetables for infants, WIC can increase dietary variety and appropriate introduction of complementary foods among infants., (Copyright © 2010 American Dietetic Association.
