Effects of household composition on infant feeding and mother–infant health in northern Kenya

Abstract

AbstractBackgroundHouseholds with alloparents, individuals other than the mother who care for an infant, can shift members' roles and affect mother–infant health.AimsTo investigate how household composition relates to infant feeding and infectious disease risk in mother–infant dyads, the team utilized data from breastfeeding dyads (n 208) surveyed during a prolonged drought and food scarcity in northern Kenya.MethodsHouseholds were classified by the presence/absence of potential alloparents, distinguishing non‐siblings and siblings of the infant. Regression models for breastfeeding frequency, complementary feeding status, and recent infections (n 83) evaluated these outcomes' associations with household type while accounting for food insecurity, adjusted for infant age, infant sex, and maternal age.ResultsHousehold type was unassociated with breastfeeding frequency, but the presence of non‐sibling alloparents interacted with food insecurity, predicting increasing breastfeeding frequency as food insecurity intensified among dyads living with non‐sibling alloparents. Households with non‐sibling alloparents were also inversely associated with complementary feeding but had no association with infection. Households with siblings were inversely associated with (protective against) infant and maternal infection.ConclusionFurther research is needed to understand the interactive influence of household social and food ecologies on mother–infant diet and health under diverse cultural rules and norms for alloparenting.
