Prevalence of psychosocial risk factors and their associations with childhood stunting in rural Tanzania.

Abstract

Childhood stunting contributes to substantial global disease and economic burden (~US$2.1 billion per day). The purpose of this study was to investigate key psychosocial factors that may increase the risk for stunting. Within this observational study, 162 mothers living in rural Tanzania completed a cross-sectional quantitative survey measuring parental substance use, intimate partner violence (IPV) and mothers' mental health (i.e., depression/anxiety). One month after survey completion, children's height and weight were measured in triplicate to assess for childhood stunting. Sequential mediation revealed that parental alcohol use (b = 0.03, SE = 0.02, 95% CI [0.003, 0.08]) and alcohol-related consequences (b = 0.07, SE = 0.05, 95% CI [0.02, 0.20]) predicted greater IPV, which, in turn, was associated with elevated maternal mental health problems and ultimately childhood stunting. This study helps to clarify the pathways through which psychosocial risk factors confer heightened risk for childhood undernutrition. Going forward, this knowledge may also help to inform preventative interventions intended to reduce childhood stunting.
