摘要
目的 探讨新型冠状病毒感染前后青少年身体形态与体质健康水平的变化情况及其相互关系,为推动青少年健康水平持续提升提供参考.方法 基于济南市青少年体质健康监测项目,采用方便抽样法,选取山东省济南市1 194名小学生作为纵向追踪调研样本,于2019年11月(T1)、2020年11月(T2)、2021年11月(T3)和2022年11月(T4)进行数据收集,分析青少年新型冠状病毒感染前后体质量指数(body mass index,BMI)-Z评分和体质健康综合得分的变化.结果 2020年青少年BMI-Z评分相较于2019年明显提升,并在2021和2022年出现下降,差异有统计学意义(F=2.934,P＜0.05);青少年的体质健康综合得分在2020年出现下降,并在2021年和2022年提升,差异有统计学意义(F=35.737,P＜0.01));构建青少年身体形态与体质健康水平的交叉滞后模型发现,身体形态T1对体质健康T2(βT1-T2=0.323,P＜0.01)、身体形态T2对体质健康T3(βT2-T3=0.300,P＜0.01)、身体形态T3对体质健康T4(βT3-T4=0.283,P＜0.01)影响差异有统计学意义.结论 新型冠状病毒感染对青少年身体形态和体质健康水平均产生了一定的影响,需有针对性地加强青少年超重肥胖的预防和干预工作.
Abstract
Objective To explore the changes in body shape and physical health levels of adolescents before and after COVID-19 infection and their interrelationships in order to provide a reference for promoting the sustainable improvement of the health levels of adolescents.Methods Based on the Youth Physical Health Monitoring Proj-ect in Jinan,a convenient sampling method was used to select 1 194 primary school students in Jinan,Shandong Province as longitudinal tracking survey samples.Data were collected longitudinally in November 2019(T1),No-vember 2020(T2),November 2021(T3),and November 2022(T4)to analyze the changes in BMI-Z scores and comprehensive physical health scores of adolescents before and after coronavirus infection.Results The BMI Z score of adolescents in 2020 showed a significant improvement compared with that in 2019 and then decreased in 2021 and 2022,with statistical significance(F=2.934,P＜0.05).The comprehensive physical and health scores of adolescents showed a decrease in 2020 and rebounded and improved in 2021 and 2022,also showing statistical significance(F=35.737,P＜0.01).The cross-lagged model body shape and physical health level were con-structed,and it was revealed significant effects of body shape at T1 on physical health at T2(βT1-T2=0.323,P＜0.01),T2 on T3(βT2-T3=0.300,P＜0.01),and T3 on T4(βT3-T4=0.283,P＜0.01).Conclusions COVID-19 infection specifically impacted the body shape and physical health level of adolescents,and targeted efforts are still needed to strengthen the prevention and intervention of overweight and obesity in adolescents.
