This study analyzed repeated cross-sectional survey data to examine how the link between household food insecurity and child undernutrition in Bangladesh varies by season and year.
The analysis investigated the association between household food insecurity (HFI) and child undernutrition (stunting, wasting, underweight), and the mediating role of child dietary diversity (CDD). The authors found that HFI was significantly associated with greater odds of child undernutrition, but the association varied across survey years and seasons. For example, HFI was associated with stunting in 2013, wasting in 2012 and 2014, and underweight in 2012 and 2013. CDD had a mediating effect in the association between HFI and child underweight, particularly during the Post-Aman harvest season. Limitations include the cross-sectional design, which prevents causal inference, and the inability to adjust for natural hazards. The findings suggest that seasonality should be considered when designing food-based interventions to combat child undernutrition.
