Abstract
OBJECTIVE: This study aimed to determine the prevalence of mother-child double burden of malnutrition (DBM) based on anthropometric indices and its associated factors in Burkina Faso. DESIGN: This cross-sectional study used nationally representative data from the 2021 Burkina Faso Demographic and Health Survey (BFDHS-V). DBM was defined as follows: overweight mother with stunted child (OM/SC); overweight mother with wasted child (OM/WC); overweight mother with underweight child (OM/UC); overweight mother with stunted or wasted or underweight child (OM/SC-WC-UC). Generalised linear model of regression using R programming was performed to identify factors associated with DBM. SETTING: Burkina Faso. PARTICIPANTS: 5286 mother-child dyads living in the same household. RESULTS: The prevalence of DBM in mother-child dyads was 4·9 % for OM/SC-WC-UC. Urban residence was inversely associated with 3 forms of dyads DBM. OM/SC-WC-UC: aOR = 0·60, 95 % CI (0·37, 0·96), OM/WC: aOR = 0·23, 95 % CI (0·11, 0·45), and OM/UC: aOR = 0·51, 95 % CI (0·29, 0·89). Higher child birth order was associated with increased odds of OM/WC: aOR = 3·82, 95 % CI (1·21, 12·10) and OM/UC: aOR = 4·75, 95 % CI (1·65-13·62). Older maternal age was associated with OM/SC: aOR = 3·17, 95 % CI (1·44, 7·00) and belonging to a wealthier household was associated with OM/SC-WC-UC: aOR = 3·43, 95 % CI (1·61, 7·30). CONCLUSIONS: The finding suggests that household-level DBM is an emerging problem in Burkina Faso. The most prevalent form of DBM includes an overweight mother with a stunted child, and common associated factors include urban residence and high socio-economic status. Urgent strategies and actions need to be put in place in order to avert this trend.
