Abstract
Purpose
There is conflicting evidence concerning the relationship between breast-feeding and development of wheezing in early childhood. Epidemiological evidence for a role of breast-feeding on risk of wheezing is inconclusive. The objective of this study was to investigate the associations between breast feeding and risk of current wheezing in early childhood in Korea.
Methods
We combined the fifth Korea National Health and Nutrition Examination Survey data collected from 2010 to 2012 and analyzed 1,011 children from 1 to 3 years olds who had been surveyed in regards to breast-feeding. Multivariate regression analysis was used to identify association among the following variables: presence of current wheezing, feeding types and duration of breast-feeding.
Results
Prevalence of exclusive breast-feeding and current wheezing decreased both annually from 2010 to 2012. In the univariate analysis, breast-feeding, formula-feeding, duration of breast-feeding were not associated significantly with current wheezing of children younger than 3 years old. No measureable statistically significant relation was observed among breast-feeding, formula-feeding, duration of breast-feeding and risk of current wheezing in the multivariate analysis.
