Background:
The aim of this study was to identify the status of exclusive breast-feeding (EBF) in Korea and analyze the factors affecting exclusive breast-feeding at 6 months of age.
Method:
This study was based on data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) IV, conducted from January 2007 to December 2008. A total of 404 mother-infant pairs were recruited. Exclusive breast-feeding was defined according to the criteria established by the World Health Organization.
Result:
The rate of EBF was 60.9% for 1 month, 55.0% for 3 months, 35.4% for 6 months, 3.7% for 9 months and 1.2% for 12 months after birth. According to a stepwise logistic regression analysis, factors that were positively associated with EBF at 6 months were younger maternal age (odds ratio [OR] = 0.85, 95% confidence interval [CI]: 0.79-0.92), higher maternal education level (OR = 2.29, 95%CI: 1.17-4.46) and living in a capital city (OR = 2.64, 95%CI: 1.46-4.75).
Conclusion:
The rate of EBF in Korea is still suboptimal. To promote EBF, persistent and systematic education and campaigns for breast-feeding should be provided, particularly in vulnerable regions.
