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.

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. 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. 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. 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. 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.

Childhood stunting holds consequences for child development. A nutrition program delivering small-quantity lipid based nutrient supplements (SQ-LNS) to children 6-23 months and child feeding messages was implemented in Malawi to reduce stunting. This study sought to understand the facilitators and barriers to program participation using in-depth interviews, pile sorts, direct observations, and focus group discussions with caretakers, village leaders and program volunteers. Perceptions of the LNS were positive, and visible changes in child health contributed to program participation. Conflicting priorities that prevented monthly collection of SQ-LNS and limited knowledge of child feeding messages constituted barriers to program participation.

Poor nutrition (substandard diet quantity and/or quality resulting in under- or overnutrition) and the lack of early learning opportunities contribut

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.
