Role of Psychosocial Factors and Mental Well-Being for Baby WASH- and Nutrition-Related Behaviors in Lao PDR.

ABSTRACT

In Lao PDR, 30% of children under age 5 years are affected by stunting. Stunting in childhood is associated with poorer outcomes for both physical and cognitive development. Baby WASH is a focused approach to water supply, sanitation, and hygiene for infants and children that targets numerous contextual and psychosocial factors including child handwashing, food hygiene, clean play spaces, and management of animal feces in the household environment. Using the risks, attitudes, norms, abilities, and self-regulation approach to behavior change (BC), the objective of this study was to investigate psychosocial factors of Baby WASH and nutrition related-behaviors, considering caregivers mental well-being, to design evidence-based BC interventions. A cross-sectional survey of 616 caregivers of a child under 2 years was conducted in Lao PDR. Caregivers well-being was significantly associated with handwashing before feeding a baby, controlling "mouthing," and the intention to exclusively breastfeed for the first 6 months. All psychosocial factors of the three behaviors were correlated with mental well-being. Results suggest that attitudinal and ability factors underlying handwashing with soap before feeding a child should be the primary focus of BC interventions. For controlling mouthing factors, interventions should target attitude and norm factors. To increase the intention of exclusive breastfeeding for the first 6 months attitude, ability, and self-regulation factors should be targeted through BC interventions. The findings of this study can be used to support the inclusion of vulnerable caregivers with poor mental well-being with BC interventions designed to improve child health and prevent stunting.
