RESUMO
Background: Although husbands may provide support during pregnancy, limited evidence exists on how to promote husbands' engagement and what impact it has. Alive & Thrive integrated nutrition-focused interventions, targeting both wives and husbands, through an existing Maternal, Neonatal, and Child Health (MNCH) platform in Bangladesh. Objectives: We evaluated 1) the impact of a nutrition-focused MNCH program, compared with the standard MNCH program, on husbands' behavioral determinants (i.e., awareness, knowledge, self-efficacy) and support to wives to adopt optimal nutrition practices and 2) how much of the previously documented impact on women's supplement intake and dietary diversity was explained by husbands' behavioral determinants and support. Methods: We used a cluster-randomized design with cross-sectional surveys at baseline (2015) and endline (2016) (n = â¼1000 women and â¼700 husbands/survey). We used mixed linear regression accounting for clustering to estimate difference-in-differences (DIDs) for impact on husbands' behavioral determinants and path analysis to examine how much these determinants explained the impact on women's nutrition behaviors. Results: Of husbands in the nutrition-focused MNCH group, 62% were counseled by health workers, 66% attended a husbands' forum, and 34% saw video shows. The nutrition-focused MNCH, compared with the standard MNCH group, resulted in greater husbands' awareness (DID: 2.74 of 10 points), knowledge (DID: 1.31), self-efficacy and social norms with regard to optimal nutrition practices (difference: 1.08), and support to their wives (DID: 1.86). Husbands' behavioral determinants and support explained nearly half of the program impact for maternal supplement intake and one-quarter for dietary diversity. Conclusions: A nutrition-focused MNCH program that promoted and facilitated husbands' engagement during their wives' pregnancies significantly improved husbands' awareness, knowledge, self-efficacy, and support. These improvements substantially explained the program's impact on women's intake of micronutrient supplements and dietary diversity. Targeting wives and husbands and designing activities to engage men in maternal nutrition programs are important to maximize impact.

Improving the nutritional status of women and children in South Asia remains a high public health and development priority. Women's groups are emerging as platforms for delivering health- and nutrition-oriented programs and addressing gender and livelihoods challenges. We propose a framework outlining pathways through which women's group participation may facilitate improvements in nutrition. Evidence is summarized from 36 studies reporting on 24 nutritional indicators across infant and young child feeding (IYCF) practices, intake/diet, and anthropometry. Our findings suggest that women's group-based programs explicitly triggering behavior change pathways are most successful in improving nutrition outcomes, with strongest evidence for IYCF practices. Future investigators should link process and impact evaluations to better understand the pathways from women's group participation to nutritional impact.
