Abstract:
Objective:To investigate prevalence and related factors of overweight and obesity in children aged 6-12 years in Yiwu of Zhejiang Province.Methods:The stratified sampling method was used to perform physical examination and questionnaire survey among 500 children aged 6-12 years from five schools in Yiwu (166 from city-level schools, 168 from district-level schools, and 166 from village-level schools). The number of children at each year of 6-12 years was 54 (10.8%), 66 (13.2%), 70 (14.0%), 69 (13.8%), 83 (16.6%), 79 (15.8%) and 79 (15.9%). The factors that affect the prevalence of overweight and obesity were analyzed.Results:Among 500 school-age children, the detection rates of overweight and obesity were 12.8% (64/500) and 11.6% (58/500), respectively. There were significant differences in the detection rates of overweight and obesity between male and female children (16.1%/9.0%, 15.4%/7.3%), among children whose fathers received different levels of education (primary school and below/junior high school/senior high school and above) (25.0%/13.1%/9.2%, 22.9%/11.2%/9.2%), among children whose mothers received different levels of education (primary school and below/junior high school/senior high school and above) (23.5%/12.9%/10.1%, 19.6%/13.3%/7.7%), among children living in cities versus villages (18.6%/8.8%, 16.7%/8.1%), among children performing exercise for different lengths of time (< 0.5 hours/0.5-1.0 hours/> 1.0-2.0 hours/> 2.0 hours) (21.2%/14.9%/13.1%/3.6%, 19.2%/13.1%/11.9%/3.6%), among children with different sleep time (< 8 hours/8-10 hours/>10 hours) (16.8%/14.2%/6.3%, 15.9%/12.7%/5.6%), among children taking dessert at different frequencies (< 3 days per week/3-5 days per week/> 5 days per week) (5.6%/10.3%/23.4%, 4.9%/9.4%/21.4%), among children taking sugary or carbonated drinks at different frequencies (< 3 days per week/3-5 days per week/> 5 days per week) (6.5%/11.2%/17.1%, 6.5%/9.4%/16.1%), and among children who took extra meals before bed (< 3 days per week /3-5 days per week /> 5 days per week) (15.8%/9.4%/20.3%, 14.3%/8.5%/19.0%) (overweight: χ2 = 5.61, 8.41, 6.74, 10.48, 17.45, 6.74, 22.43; obesity: χ2 = 7.88, 6.28, 6.58, 8.63, 14.76, 6.74, 20.69, all P < 0.05). Multivariate logistic regression analysis showed that boys, unbalanced diet and extra meals before bed are independent risk factors for overweight and obesity in school-age children (all P < 0.05). Sleep time, exercise time and mother's education were protective factors of overweight and obesity (all P < 0.05). Conclusion:The incidences of overweight and obesity among school-age children aged 6-12 years in Yiwu of Zhejiang province are high, and sex, mother's education level, diet, exercise and sleep are the main influential factors of overweight and obesity.
