[Association between screen time, sugar-sweetened beverage intake and different types of obesity among primary and secondary school students in Jiangsu Province in 2023].
摘要
OBJECTIVE: To explore the relationship between screen time, sugar-sweetened beverage(SSB) intake and different types of obesity(obesity defined by body mass index(BMI), abdominal obesity and high BMI combined with high waist circumference(WC)). METHODS: Relying on the 2023 Surveillance and Intervention Project for Common Disease and Health Risk Factors among Students in Jiangsu Province, stratified random cluster sampling method was used to select a total of 142 113 primary and secondary school students from 13 cities in Jiangsu Province. Students' height, weight, and WC were collected through physical examinations. In accordance with the requirements of Screening for Overweight and Obesity in School-Age Children and Adolescents(WS/T 586-2018) and High Waist Circumference Screening Threshold among Children and Adolescents Aged 7-18 Years(WS/T 611-2018), different types of obesity were determined based on the above-mentioned indicators. General demographic information of students(including gender, school stage, place of residence, etc. ) and behavioral lifestyle information(including screen time, SSB intake, etc. ) were collected via questionnaires. Binary Logistic regression was used to analyze the association between screen time and SSB intake and different types of obesity in primary and secondary school students. RESULTS: In 2023, among primary and secondary school students in Jiangsu Province, boys accounted for 52.1%(n=74 053) and girls accounted for 47.9%(n=68 060); primary school students accounted for 33.5%(n=47 568), junior high school students accounted for 33.3%(n=47 408), and senior high school students accounted for 33.2%(n=47 137); students in urban areas accounted for 55.8%(n=79 293) and students in suburban and county areas accounted for 44.2%(n=62 820). The detection rate of obesity defined by BMI, abdominal obesity and high BMI combined with high WC among primary and secondary school students in Jiangsu Province was 19.6%(n=27 859), 30.2%(n=42
