Abstract:
Objective To investigate the trends and risk factors of overweight and obesity in Chinese middle school students. Methods Data from the China Education Panel Survey conducted in 2014, 2015 and 2016 were used (8 616, 8 762, 7 614; age range 11-18 years old). Overweight and obesity were defined according to Chinese sex-age-specific body mass index (BMI) cutoffs. Relationships between risk factors and BMI, overweight and obesity were tested, using linear regression and logistic regression models. Results The overall prevalence of overweight and obesity in 2016 was 15.3% (17.9% in boys, 12.6% in girls). From 2014 to 2016, the prevalence of overweight and obesity was increasing steadily. After adjusting for age and sex in 2016, being only-child, self-perceived being overweight or obese, or living in urban area were associated with higher BMI (β(SE)=0.23(0.10), β(SE)=2.83(0.14), β(SE)=0.23(0.11), respectively). Self-perceived being overweight or obese was associated with overweight and obesity (OR=4.20, 95% CI: 2.97-5.40). Conclusions Overweight and obesity rates among Chinese middle school students increased steadily from 2014 to 2016. Efforts should be made on childhood obesity prevention and control, especially target at those being only-child, living in urban areas.
