The practice of exclusive breastfeeding by region in Indonesia.

OBJECTIVE: Exclusive breastfeeding has important benefits for both children and mothers. However, the proportion of exclusive breastfeeding is still not evenly distributed among regions, including in Indonesia. The purpose of this study was to analyze the practice of exclusive breastfeeding by region in Indonesia and its influencing factors.

STUDY DESIGN: This study was cross-sectional study.

METHODS: This study used secondary data from the Indonesia Demographic and Health Survey 2017. The total sample was 1621 respondents, which consisted of mothers whose last child was under six months old and was still alive; the mothers did not have twins and lived with their child. Data were analyzed by using Quantum GIS and binary logistic regression statistical tests.

RESULTS: This study shows that 51.6% of respondents gave exclusive breastfeeding in Indonesia. The highest proportion was in the Nusa Tenggara region (72.3%), whereas the lowest was in Kalimantan province (37.5%). Mothers who lived in the regions of Nusa Tenggara, Sulawesi, Java-Bali, and Sumatra had a higher chance of exclusive breastfeeding compared to those in the Kalimantan region. The factors associated with the exclusive breastfeeding vary widely across all regions, and the child's age is the only common factor associated with the exclusive breastfeeding in all regions, except Kalimantan.

CONCLUSION: This study shows wide variation in regional proportions and determinants of exclusive breastfeeding in Indonesia. Therefore, appropriate policies and strategies are needed to increase equitable exclusive breastfeeding practices across all regions in Indonesia.
