[Study design and characteristics of participants in baseline investigation Zhejiang Childhood Behavior and Health Cohort].
摘要
The behavioral and health issues of children and adolescents have become one of the most significant public health challenges with global concern. A cohort study is an ideal approach for exploring the relevant factors associated with these issues and evaluating the possible effectiveness of interventions among children and adolescents. Thus, from September 2024 to January 2025, we selected 6 counties in Zhejiang Province to establish the Zhejiang Childhood Behavior and Health Cohort, aiming to explore the changing patterns, relevant factors, and long-term health effects of behavior and health issues among children and adolescents. This study will introduce the cohort design and conduct descriptive analyses on the main characteristics of participants in the baseline survey. Overall, 21 698 participants aged 6-19 years (mean age, 11.6 years) were recruited, comprising 53.2% males and 68.4% from rural areas. The proportion of ever smoking was 3.6% in males and 2.0% in females. 75.9% of males and 73.3% of females were trying to control their weight. The mean height, weight, and waist circumference of males was (152.8±18.7) cm, (47.0±18.2) kg and (66.6±12.0) cm, respectively, and of females was (148.8±15.7) cm, (42.2±14.2) kg and (62.3±9.4) cm, respectively. The result for the 50-meter dash was 8.8 s in males and 9.4 s in females.
