Breastfeeding practices in Northeast China in 2008 and 2018: cross-sectional surveys to explore determinants over a decade

BACKGROUND: This study was conducted to investigate the prevalence and determinants of breastfeeding in 2008 and 2018, respectively, in Northeast China, where health service efficiency is at the lowest national level and regional data on breastfeeding are lacking. The influence of early initiation of breastfeeding on later feeding practices was specifically explored. METHODS: Data from the China National Health Service Survey in Jilin Province in 2008 (n = 490) and 2018 (n = 491) were analysed. Multistage stratified random cluster sampling procedures were used to recruit the participants. Data collection was conducted in the selected villages and communities in Jilin. Early initiation of breastfeeding was defined as the proportion of children born in the last 24 months who were put to the breast within one hour after birth in both the 2008 and 2018 surveys. Exclusive breastfeeding was defined as the proportion of infants 0–5 months of age who were fed exclusively with breast milk in the 2008 survey; while defined as the proportion of infants 6–60 months of age who had been fed exclusively with breast milk within the first six months of life in the 2018 survey. RESULTS: The prevalence of early initiation of breastfeeding (27.6% in 2008 and 26.1% in 2018) and exclusive breastfeeding during the first six months (< 50%) were low in two surveys. Logistic regression revealed that exclusively breastfeeding at six months was positively associated with early initiation of breastfeeding (OR 2.65; 95% confidence interval (CI) 1.65, 4.26) and negatively associated with caesarean section (OR 0.65; 95% CI 0.43, 0.98) in 2018. Continued breastfeeding at one year and timely introduction of complementary foods were associated with maternal residence and place of delivery, respectively, in 2018. Early initiation of breastfeeding was associated with mode and place of delivery in 2018 but residence in 2008. CONCLUSION: Breastfeeding practices in Northeast China are far from optimal. The negative effect of caesarean section and positive effect of early initiation of breastfeeding on exclusive breastfeeding suggest that an institution-based approach should not be substituted by the community-based one in the formulation of breastfeeding strategies in China.
