Objectives:To explore the role of individual-level and household-level characteristics for practice of nutrition-specific and nutrition-sensitive interventions. Design: Secondary data analysis (cross-sectional). Setting: West and Central Africa. Participants: Data are from the Demographic and Health Surveys in the time period between 1986 and 2016. The final sample included between 116325 and 272238 observations depending on the outcome. Primary and secondary outcome measures: Nutrition-specific and nutrition-sensitive interventions were identified based on the UNICEF Conceptual Framework for child undernutrition. These were early breastfeeding initiation, minimum dietary diversity, full age-appropriate immunisation, iodised salt usage, vitamin A supplementation, iron supplementation, deworming in children aged 1 to 5, clean cooking fuel, safe drinking water and improved sanitation. Explanatory variables include household, mother and child characteristics. Linear probability models were fitted for each outcome, both unadjusted as well as fully adjusted including primary sampling unit fixed effects. Results: Prevalence of early breastfeeding initiation was 54.31% (95%CI: 53.22% to 55.41%), minimum dietary diversity 13.89% (95%CI: 13.19% to 14.59%), full age-appropriate immunisation 13.04% (95%CI: 12.49% to 13.59%), iodised salt usage 49.66% (95%CI: 46.79% to 52.53%), vitamin A supplementation 52.87% (95%CI:51.41% to 54.33%), iron supplementation 10.73% (95%CI:10.07% to 11.39%), deworming 31.33% (95% CI: 30.06% to 32.60%), clean cooking fuel usage 3.02% (95% CI: 2.66% to 3.38%), safe drinking water 57.85% (95% CI: 56.10% to 59.59%) and improved sanitation 42.49% (95% CI: 40.77% to 44.21%). There was a positive education and wealth gradient for the practices of all interventions except deworming. Higher birth order was positively associated with the practice of early breastfeeding initiation, minimum dietary diversity, vitamin A supplementation and negatively associated with full immunisation and improved sanitation. Conclusions: Household, maternal, and child-level characteristics explain practices of nutrition-specific and nutrition-sensitive interventions beyond intervention delivery at the regional level.
