Abstract / Description
ObjectiveTo identify lifestyle and dietary factors associated with obesity in children during the first 6 years of life.MethodsChildren aged 0-6 years were recruited from 12 Children's Health Care Centers in Jiangsu, China, by a multistage stratified cluster random-sampling method. Diet, sleep, supplementation and outdoor activity were collected by questionnaire/interview. Obesity was defined as Body mass index Z-score >2 (World Health Organization standards). Logistic regression was used to examine the associations between lifestyle/dietary factors and obesity, adjusting for sex, age, delivery mode, birth weight, region, and season, with additional stratified and restricted cubic spline dose-response analyses.ResultsA survey of 5,243 children were enrolled in the present study. Prevalence varied by characteristics: sleep 14 h (9.9%), outdoor activity 150 g (11.2%), and daily egg >60 g (11.1%). Adjusted analyses identified higher obesity odds for sleep 14 h (2.503, 1.640-3.820), outdoor activity 14 h, outdoor activity 150 g/day remained statistically significant.
