Abstract:
Objective:To investigate the associations between behavioral risk factors and overweight or obesity among schoolage children and adolescents in Shanghai, and to provide a reference for making targeted prervention and control measures for overweight and obesity.
Methods:A total of 11 913 children and adolescents aged 9-18 years old were selected according to 2014 Shanghai Physical Fitness and Health Surveillance. Questionnaire survey and physical examination including height, weight and other physical index were performed. Logistic regression was used to analyze the association between overweight or obesity and sleep time, diet, physical exercise and sedentary behavior
Results:The prevalence of overweight or obesity was higher among boys who slept longer than or equal to 10 hours(36.7%), compared with those with less than 8 hours of sleep(31.3%)(P<0.01). The rates of overweight or obesity in girls was higher among breakfast skippers(36.4%) than breakfast nonskippers(17.6%)(P<0.05). The prevalence of overweight or obesity was higher among pupils who did not like physical education(38.2%) than those who preferred(30.8%)(P<0.01). The prevalence of overweight or obesity among junior middle school students playing video games and computer over 2 hours(28.1%) was higher than those playing less than 1 hours(23.0%)(P<0.05). Unwilling to participate in longdistance running exercise, watching TV more than 1h per day were risk factors for overweight or obesity(OR=1.16, 95%CI:1.05-1.27; OR=1.22, 95%CI:1.05-1.43, respectively).Girls who were breakfast nonskippers had a lower risk of overweight or obesity (OR=0.33, 95%CI:0.16-0.67). Students in urban areas who watch TV more than 1h per day was risk factor for overweight or obesity(OR=1.36, 95%CI:1.07-1.74). Students in rural areas who slept longer than 10 hours had an increased risk of being overweight or obese (OR=2.0, 95%CI:1.23-3.25). Pupils who played video games and computers for more than 2 hours had an increased risk of being overweight or obese(OR=1.45, 95%CI:1.01-2.08).
Conclusion:In 2014, overweight or obesity among Shanghai’s primary and middle school students was highly interconnected with bad dietary behavior, static life style, and the distribution of factors shows obvious population characteristics.
