Abstract
Background: The importance of breastfeeding is well known. One of important factors affecting breastfeeding is socioeconomic status. We investigated the relationship between socioeconomic status and breastfeeding to promote future breastfeeding projects.Methods: Data were collected from the 2013 - 2017 Korea National Health and Nutrition Examination Survey (KNHANES). We evaluated the demographic information and parents’ socioeconomic status of 814 children, aged 12 ~ 60months.Results: Of the 814 children, 743 (92.2%) were breastfed. In univariate analysis, parents’ age and education level were related to breastfeeding (P < 0.05). In logistic regression analysis, mothers’ education level (≤ 13 years: odd ratio[OR], 8.57; 95% confidence interval [CI], 2.73-26.87), mothers’ income level (third quartile: OR, 2.94; 95% CI, 1.2-7.23), fathers’ age (20s: OR, 0.3; 95% CI, 0.09-0.98), fathers’ education level (10-12years: OR 4.85; 95% CI, 1.4-16.76 and 13years: OR, 18.55; 95% CI, 5.23-65.81), fathers’ income (third quartile: OR, 2.72; 95% CI 1.02-7.22) were associated with breastfeeding (P < 0.05).Conclusion: Higher parental income and education level and fathers’ age were positively associated with breastfeeding in Korea. The establishment of future breastfeeding projects should be considered target parents in Korea and other countries.
