Influence of care group participation on infant and young child feeding, dietary diversity, WASH behaviours and nutrition outcomes in rural Zimbabwe

Abstract

BackgroundThe care group approach (CGA) is a community-based nutrition behaviour change strategy centred on ‘peer-to-peer learning’ through women support groups.ObjectiveTo assess the impact of the CGA on the adoption of appropriate infant and young child feeding (IYCF), dietary diversity and water, sanitation and hygiene (WASH) practices, and associated nutrition-related outcomes.MethodsA retrospective cohort study used a mixed-method approach in selected rural districts in Zimbabwe in June 2022. A structured questionnaire was used to collect data on IYCF, diet quality, WASH and child morbidity. Binary logistic regression was used to evaluate the association between exposure and outcome. Significance was at p<0.05.ResultsA total of 127 exposed and 234 controls were enrolled. There was no significant difference between exposed and controls on the prevalence of; diarrhoea (p=0.659), cough (p=0.191) and fever (p=0.916). No significant difference was observed in the proportion ever breastfed (p=0.609), Children with Adequate Dietary Diversity Score (p=0.606) across the two groups. However, the proportion of families with adequate Household Dietary Diversity Score (HDDS) (p=0.005) and Minimum Dietary Diversity for Women (MDD-W) (p=0.009) were significantly higher in exposed than controls. Knowledge on all promoted behaviours was significantly higher in the exposed than in controls with the exception of exclusive breast feeding. While the practices were significantly higher in exposed compared with controls for: ‘Appropriate complementary feeding for children aged 6–24 months’ (p=0.001), ‘good nutrition for women of reproductive age’ (p=0.001), ‘production and consumption of diverse nutritious food’ (p=0.001) and ‘production and consumption of biofortified crops’ (p=0.001).ConclusionsThe results showed that CGA potential to increase knowledge and achieve nutrition and health-related behaviour change in low-income settings if integrated into existing community programmes. Interestingly, HDDS and MDD-W were significantly higher in exposed than controls. However, more research is required to obtain conclusive results.
