摘　　要：目的 分析中小学生户外活动、久坐行为和睡眠时长相互替代后对视力不良风险的影响,为儿童青少年近视防控精准干预提供参考依据。方法 2023年3-5月,采用分层整群随机抽样方法,选取安徽省合肥市、芜湖市、宿州市和池州市6 132名四至十二年级中小学生,通过问卷调查收集基本信息及户外活动、久坐行为和睡眠时长,采用5 m标准对数视力表进行视力检查。分别采用单一活动模型、分割模型以及等时替代模型分析中小学生户外活动、久坐行为和睡眠时长与视力不良之间的关联,并按性别进行分层分析。结果 6 132名中小学生视力不良检出率为76.9%,其中女生视力不良检出率(81.1%)高于男生(72.6%),差异有统计学意义(χ^(2)=61.37,P<0.01)。单一活动模型和分割模型结果显示,中小学生户外活动和睡眠时长与视力不良风险降低均相关(OR值分别为0.87,0.88;0.88,0.91),久坐行为时长与视力不良风险增加均相关(OR值分别为1.05,1.03)(P值均<0.05)。等时替代模型分析结果显示,用1 h/d的户外活动时长替代相同时间的久坐行为可降低15%的视力不良风险(OR=0.85);用1 h/d的睡眠时长替代相同时间的久坐行为可降低12%的视力不良风险(OR=0.88)(P值均<0.05)。按性别分层后等时替代模型分析结果显示,用1 h/d的户外活动和睡眠时长替代相同时间的久坐行为可降低男生22%和8%的视力不良风险(OR值分别为0.78,0.92);用1 h/d的睡眠时长替代相同时间的久坐行为可降低女生18%的视力不良风险(OR=0.82)(P值均<0.05)。结论 男生每日用1 h户外活动替代久坐行为以及男、女生每日用1 h睡眠替代久坐行为均可减少视力不良风险。Objective To analyze the effects of outdoor activities,sedentary behaviors and sleep duration on the risk of poor vision among primary and secondary school students after replacing them with each other,so as to provide a reference for precise intervention in the prevention and control of myopia among children and adolescents.Methods From March to May 2023,a stratified cluster random sampling method was used to select 6132 students in grades 4 to 12 in Hefei,Wuhu,Suzhou and Chizhou cities in Anhui Province.A questionnaire survey was conducted to collect the basic information,outdoor activities,sedentary behavior,and sleep duration,and a visual inspection was carried out by 5 m standard logarithmic visual acuity chart.The single activity model,segmentation model and isotemporal substitution model were used to analyze the relationship between outdoor activities,sedentary behaviors,sleep,and poor vision,and stratified analysis was performed by gender.Results The detection rate of poor vision among the 6132 primary and secondary school students was 76.9%,and the detection rate of poor vision was higher for girls(81.1%)than for boys(72.6%),and the difference was statistically significant(χ^(2)=61.37,P<0.01).The results of the single activity model and segmentation model showed that outdoor activity and sleep duration were correlated with a reduced risk of poor vision in primary and secondary school students(OR=0.87,0.88;0.88,0.91),while sedentary behavior was correlated with an increased risk of poor vision(OR=1.05,1.03)(P<0.05).The results of the isotemporal substitution model showed that replacing the same amount of sedentary behavior with 1 h/d of outdoor activity was associated with 15%reduction in the risk of poor vision(OR=0.85),and replacing the same amount of sedentary behavior with 1 h/d of sleep was associated with a 12%reduction in the risk of poor vision(OR=0.88)(P<0.05).The results of the isotemporal substitution model stratified by gender showed that replacing the same amount of sedentary behavior with 1
