World Health Organization infant and young child feeding indicators and their associations with child anthropometry: a synthesis of recent findings

As the World Health Organization (WHO) infant and young child feeding (IYCF) indicators are increasingly adopted, a comparison of country-specific analyses of the indicators\u27 associations with child growth is needed to examine the consistency of these relationships across contexts and to assess the strengths and potential limitations of the indicators. This study aims to determine cross-country patterns of associations of each of these indicators with child stunting, wasting, height-for-age z-score (HAZ) and weight-for-height z-score (WHZ). Eight studies using recent Demographic and Health Surveys data from a total of nine countries in sub-Saharan Africa (nine), Asia (three) and the Caribbean (one) were identified. The WHO indicators showed mixed associations with child anthropometric indicators across countries. Breastfeeding indicators demonstrated negative associations with HAZ, while indicators of diet diversity and overall diet quality were positively associated with HAZ in Bangladesh, Ethiopia, India and Zambia (P \u3c 0.05). These same complementary feeding indicators did not show consistent relationships with child stunting. Exclusive breastfeeding under 6 months of age was associated with greater WHZ in Bangladesh and Zambia (P \u3c 0.05), although CF indicators did not show strong associations with WHZ or wasting. The lack of sensitivity and specificity of many of the IYCF indicators may contribute to the inconsistent associations observed. The WHO indicators are clearly valuable tools for broadly assessing the quality of child diets and for monitoring population trends in IYCF practices over time. However, additional measures of dietary quality and quantity may be necessary to understand how specific IYCF behaviours relate to child growth faltering

Reply to Correspondence: is the strength of association between indicators of dietary quality and the nutritional status of children being underestimated?

Information Diffusion and Social Norms Are Associated With Infant and Young Child Feeding Practices in Bangladesh

Background Interaction within mothers’ social networks can theoretically diffuse messages from interventions and campaigns into norms and practices for infant and young child feeding (IYCF). Objectives We hypothesized that mothers’ social networks, diffusion of information, and social norms differed in intensive [intensive interpersonal counseling (IPC), community mobilization (CM), and mass media (MM)] compared with nonintensive (standard IPC and less-intensive CM and MM) intervention areas, were associated with IYCF practices, and partly explained practice improvement. Methods We conducted household surveys at endline in 2014 and follow-up in 2016 (n = ∼2000 each round). We used multiple regression to test differences and changes in networks, diffusion, and norms within intervention areas. We analyzed paths from intervention exposure to IYCF practices through networks, diffusion, and norms. Results Mothers’ networks were larger in intensive than in nonintensive areas in 2014 and increased in both areas over time [25–38 percentage points (pp)]. The prevalence of receipt of IYCF information was high, with no changes over time in intensive areas but an increase in nonintensive areas (8–16 pp). In both areas, more family members and health workers provided IYCF information over time. Sharing of information increased 17–23 pp in intensive and 11–41 pp in nonintensive areas over time. Perceived descriptive norms improved 8–16 pp in intensive and 17–28 pp in nonintensive areas. Perceived injunctive norms were high in both areas. Breastfeeding practices were associated with networks, diffusion, and norms (OR: 1.6–4.4 times larger comparing highest with lowest quartile). Minimum dietary diversity was associated with larger networks and diffusion (OR: 1.5–2.2) but not with social norms. Indirect paths from intervention exposure to practices explained 34–78% of total effects. Conclusions Diffusion of IYCF information through social networks, reinforced by positive social norms for messages promoted over time, will contribute to positive changes in IYCF practices that may be achieved and sustained through large-scale social and behavior change interventions.

Lipid-Based Nutrient Supplements Increase Energy and Macronutrient Intakes from Complementary Food among Malawian Infants.

BACKGROUND: Low intakes of good-quality complementary foods (CFs) contribute to undernutrition and consequently negatively affect health, growth, and development. Lipid-based nutrient supplements (LNSs) are designed to ensure dietary adequacy in micronutrients and essential fatty acids and to provide some energy and high-quality protein. In populations in which acute energy deficiency is rare, the dose-dependent effect of LNSs on CF intakes is unknown. OBJECTIVE: The objective of this study was to evaluate the difference in energy and macronutrient intakes from CF between a control (no supplement) group and 3 groups that received 10, 20, or 40 g LNS/d. METHODS: We collected repeated interactive 24-h dietary recalls from caregivers of rural Malawian 9- to 10-mo-old infants (n = 748) to estimate dietary intakes (LNS and all non-breast-milk foods) of energy and macronutrients and their dietary patterns. All infants were participating in a 12-mo randomized controlled trial to investigate the efficacy of various doses of LNS for preventing undernutrition. RESULTS: Dietary energy intakes were significantly higher among infants in the LNS intervention groups than in the control group (396, 406, and 388 kcal/d in the 10-, 20-, and 40-g LNS/d groups, respectively, compared with 345 kcal/d; each pairwise P < 0.05), but no significant differences were found in energy intakes between groups who were administered the different LNS doses (10 g LNS/d compared with 20 g LNS/d: P = 0.72; 10 g LNS/d compared with 40 g LNS/d: P ≥ 0.67; 20 g LNS/d compared with 40 g LNS/d: P = 0.94). Intakes of protein and fat were significantly higher in the LNS intervention groups than in the control group. No significant intergroup differences were found in median intakes of energy from non-LNS CFs (357, 347, and 296 kcal/d in the 10-, 20-, and 40-g LNS/d groups, respectively, compared with 345 kcal/d in the control group; P = 0.11). CONCLUSION: LNSs in doses of 10-40 g/d increase intakes of energy and macronutrients among 9- to 10-mo-old Malawian infants, without displacing locally available CFs.
