【摘要】 目的 了解2019—2021年西安市儿童青少年筛查性近视共患超重/肥胖流行现状，并探讨视屏时间与户外活动时间对其的影响，为近视、超重/肥胖的多病共防提供参考。方法 选取2019—2021年西安市学生常见病监测的12所学校学生为研究对象，对小学4～6年级、初中和高中各年级进行分层整群抽样。描述筛查性近视共患超重/肥胖现状，采用χ~2检验、多元logistic回归对共患病的影响因素进行分析。结果 2019—2021年共纳入儿童青少年5 768人，其中小学4～6年级1 877人（32.54%），初中1 928人（33.43%），高中1 963人（34.03%）;3年筛查性近视共患超重/肥胖的共患率分别为27.4%(985/3 601)、16.1%(168/1 041)、27.4%(308/1 126)，变化呈J型曲线。3年总共患率为25.3%(1 461/5 768)；共患率为城区高于郊县、男生高于女生、随学段呈上升趋势（均P<0.01）。视屏时间≥2 h/d是小学4～6年级儿童青少年筛查性近视共患超重/肥胖的危险因素（OR=2.111）。户外活动时间≥2 h/d是小学4～6年级和初中儿童青少年筛查性近视共患超重/肥胖的保护因素（OR=0.531、0.544）。结论 减少视屏时间和增加户外活动时间能降低儿童青少年筛查性近视共患超重/肥胖发生。更多还原

【Abstract】 Objective To understand the prevalence and influencing factors of screening myopia combined with overweight/obesity in children and adolescents from 2019 to 2021 in Xi’an City,and to provide a reference for the co-prevention of myopia and overweight/obesity.Methods from 2019 to 2021 were selected for this study,and stratified cluster sampling was carried out in grades 4 to 6 of primary school,junior high school,and senior high school. To describe the status quo of screening myopia combined with overweight/obesity,χ~2 test and multiple logistic regression were used to analyze the influencing factors of comorbidity.Results From 2019 to 2021,a total of 5 768 children and adolescents were included,including 1 877(32.54%)in grades 4 to 6 of primary school,1 928(33.43%)in junior high school,and 1 963(34.03%)in senior high school. The co-incidence rates of screening myopia and overweight/obesity from 2019 to 2021 were 27.4%(985/3 601),16.1%(168/1 041),and27.4%(308/1 126),respectively,with a J-shaped curve. The 3-year total co-incidence rate was 25.3%(1 461/5 768). The co-incidence rate was higher in urban area than in suburban county,higher in boys than in girls,and increased with phase of studying(all P<0.01). Video time ≥2 h/d was a risk factor for screening myopia combined with overweight/obesity in grades 4 to 6 of primary school students(OR=2.111). Outdoor activity time ≥2 h/d was a protective factor for screening myopia combined with overweight/obesity in grades 4 to 6 of primary school students and junior high school students(OR=0.531,0.544).ConclusionsReducing video time and increasing outdoor time can reduce the incidence of screening myopia combined with overweight/obesity in children and adolescents.更多还原
