Abstract: Objective To understand the epidemiologic status of overweight and obesity among children and adolescents aged 6 to 17 years in Henan Province, and to explore the influencing factors, in order to provide reference for developing effective intervention measures. Methods Questionnaire survey and physical examination were conducted among 6- to 17-year-old students with a stratified cluster sampling method in seven cities of Henan Province in 2019. Chi-square, one-way analysis of variance and Logistic regression model were used to data analysis. Results A total of 19 390 children and adolescents were included in this study. The detection rate of overweight and obesity was 42.3%, of which 4 415 (22.8%) weredetected with overweight and 3 790 (19.5%) were detected with obesity. The detection rates of overweight and obesity in the 10 390 boys were 23.0% and 20.8%, respectively. The detection rates of overweight and obesity in the 9 000 girls were 22.5% and 18.1%, respectively, which were significantly lower than those of boys. The detection rates of overweight and obesity in elementary school students were higher than those of high school students and junior high school students. Multivariate Logistic regression analysis showed that risk factors of overweight and obesity included paternal overweight (OR=1.842), maternal overweight (OR=2.586), preferring to eat sweets and puffed food (OR=3.161), eating too fast (OR=3.268), eating out frequently (OR=1.882), watching TV and playing mobile phone for more than 2 hours everyday (OR=2.376) and insufficient sleep time everyday (OR=2.640). Conclusion The detection rates of overweight and obesity among children and adolescents are relatively high in Henan Province, so targeted intervention measures should be implemented to reduce the prevalence of overweight and obesity effectively.
