Maternal exposure to a radio programme and maternal and child nutrition-related practices: cross-sectional analyses of the 2022 Nepal Demographic and Health Survey.

This paper examines associations between maternal exposure to a radio programme, Bhanchhin Aama (Mother Knows Best), and the programme's most promoted maternal and child nutrition-related practices, using the Nepal Demographic and Health Survey (NDHS) from 2022. We limited our sample to mothers of children less than 2 years (n = 1,933). The primary exposure variable was whether the mother listened to the Bhanchhin Aama radio programme. The five primary outcomes were: maternal dietary diversity, maternal use of modern family planning methods, exclusive breastfeeding (EBF) of children less than 6 months, dietary diversity among children 6 to 24 months, and participation in growth monitoring and promotion among children 0 to 24 months. Descriptive analyses followed by logistic regression models, adjusted for potentially confounding factors and clustering, were conducted. Maternal exposure to Bhanchhin Aama was associated with nearly 70% higher odds of meeting both maternal (OR: 1.67; p: <0.001; CI: 1.26-2.21) and child minimum dietary diversity (OR: 1.70; p: 0.005; CI: 1.18-2.45), as well as 83% higher odds of a child participating in growth monitoring and promotion (OR: 1.83; p: 0.001; CI: 1.28-2.63). No associations were found for use of modern family planning methods and EBF. These findings suggests that radio programmes may be an effective tool to improve some maternal and child nutrition-related practices. Further research is needed to understand why certain behaviours are modifiable from this type of intervention versus others that are not and for which population groups this intervention would be most effective.
