Abstract

OBJECTIVES
The aim of this study is to find the association between mothers' working hours and obesity of their children according to children's age and gender.
METHODS
This study used data from the second and third year of KNHANES IV and the first year in KNHANES V (2008-2010). We calculate odds ratio (OR) and 95% confidence interval (CI) by using survey logistic regression to assess association of mother's working hours with overweight or obesity of her children. The model was adjusted with household income, mothers' education and obesity and mothers' job characteristics.
RESULTS
13-18 aged boys whose mothers worked under 40 hours per week were higher risk for obesity and overweight (including obesity) than 13-18 aged boys whose mothers worked 40-48 hours. 6-12 aged girls whose mothers worked 49-60 hours per week were more overweight (including obesity) than girls whose mothers worked 40-48 hours per week. 13-18 aged girls whose mothers worked over 60 hours were more overweight (including obesity) than the reference.
CONCLUSION
This study showed that girls' obesity was associated with mothers' long working hours. Long working hours can influence health of workers' family.
