Association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children

Abstract

Objective: To determine the association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children. Method: Data were obtained from 897 children aged 6 to 12 years. A questionnaire was used to collect information. Body mass index (BMI) was determined using the age- and gender-specific Centers for Disease Control and Prevention definition. Children were categorized as: normal weight (5th percentile <= BMI < 85th percentile), at risk for overweight (85th <= Bmi < 95th 73 percentile), overweight (>= 95th percentile). For the analysis, overweight was defined as BMI at or above the 85th percentile for each gender. Adjusted odds ratios (adjusted ORs) for physical inactivity were determined using a logistic regression model. Results: The prevalence of overweight was 40.7\%, and of sedentary lifestyle, 57.2\%. The percentage of non-intact families was 23.5\%. Approximately 48.7\% of the mothers had a non-acceptable educational level, and 38.8\% of the mothers worked outside of the home. The logistic regression model showed that living in a non-intact family household (adjusted OR = 1.67; 95\% CI = 1.04-2.66) is associated with sedentary lifestyle in overweight children. In the group of normal weight children, logistic regression analysis show that living in a non-intact family, having a mother with a non-acceptable education level, and having a mother who works outside of the home were not associated with sedentary lifestyle. Conclusion: Living in a non-intact family, more than low maternal educational level and having a working mother, appears to be associated with sedentary lifestyle in overweight primary school-age children.
