Complementary feeding practices and associated factors among mothers of children aged 6 to 23 months in Sub-saharan African countries: a multilevel analysis of the recent demographic and health survey

Abstract

Abstract Introduction Malnutrition is a public health problem in sub-Saharan Africa with an increased morbidity and mortality rate than in other parts of the world. Poor complementary feeding practices are one of the major causes of malnutrition during the first two years of life. Therefore, this study aimed to determine the prevalence and associated factors of appropriate complementary feeding practices among mothers of children aged 6 to 23 months in sub-Saharan African countries. Methods A multilevel mixed-effect analysis was carried out using recent demographic health survey data from 19 sub-Saharan African countries, which were conducted between 2015 and 2020. A total weighted sample of 60,266 mothers of children aged 6 to 23 months were included in the study. The demographic health survey employs a stratified two-stage sampling technique. Data extracted from the recent DHS data sets were cleaned, recorded, and analyzed using STATA/SE version 14.0 statistical software. Multilevel mixed-effects logistic regression was used to determine the factors associated with complementary feeding practice. Variables with a p-value less than 0.05 and adjusted odds ratio (AOR) with a 95% confidence interval (CI) were reported as statistically significant variables associated with appropriate complementary feeding practices. Results The prevalence of appropriate complementary feeding practices among mothers of children aged 6 to 23 months in sub-Saharan African countries was 13.02% (95% CI: 12.75–13.29%). Maternal educational level [AOR = 0.69, 95% CI (0.64, 0.74)] and [AOR = 0.52, 95% CI (0.47, 0.57)], marital status of the mother [AOR = 0.85, 95% CI (0.74, 0.96)], sex of household head [AOR = 1.78, 95% CI (1.09, 1.27)], total children ever born [AOR = 1.52, 95% CI (1.18, 1.96)], [AOR = 1.43, 95% CI (1.14, 1.81)], and [AOR = 1.31, 95% CI (1.04, 1.64)], media exposure [AOR = 0.74, 95% CI (0.69, 0.79)], ANC visits attended during pregnancy [AOR = 0.73, 95% CI (0.63, 0.80)] and [AOR = 0.67, 95% CI (0.62, 0.74)], place of delivery [AOR = 0.92, 95% CI (0.85, 0.98)], currently breastfeeding [AOR = 1.12, 95% CI (1.01, 1.23)], PNC checkup [AOR = 0.75, 95% CI (0.70, 0.80)], the current age of the child [AOR = 0.26, 95% CI (0.24, 0.28)] and [AOR = 0.14, 95% CI (0.13, 0.16)], birth order [AOR = 1.31, 95% CI (1.09, 1.58)], number of under 5 children in the household [AOR = 0.76, 95% CI (0.59, 0.97)], community illiteracy [AOR = 1.09, 95% CI (1.02, 1.18)], and country category [AOR = 1.62, 95% CI (1.18, 2.22)] were significantly associated with appropriate complementary feeding practices. Conclusion The prevalence of appropriate complementary feeding practices among mothers of children aged 6 to 23 months in sub-Saharan Africa was relatively low. Higher maternal educational level, female household head, having media exposure, attending more ANC visits, health facility delivery, currently breastfeeding, having PNC follow-up, low community illiteracy, and living in the West Africa region increase the odds of appropriate complementary feeding practices. Women empowerment, increasing maternal health services accessibility, promoting breastfeeding behavior, increasing media exposure of the household, and improving the proportion of health facility delivery are strongly recommended.
