摘　　要：目的应用潜在类别分析宁波市鄞州区中小学生行为生活方式对近视的影响,为预防中小学生近视提供参考。方法采用分层整群抽样方法抽取鄞州区6所中小学校1547名学生,通过问卷调查收集与近视相关的行为生活方式,并进行近视筛查。对中小学生近视相关的行为生活方式进行潜在类别分析,采用logistic回归模型分析不同行为生活方式类别与近视的关系。结果发放问卷1547份,回收有效问卷1494份,问卷有效率为96.57%。调查小学247人,占16.53%;初中452人,占30.25%;高中532人,占35.61%;职业高中263人,占17.60%。男生773人,占51.74%;女生721人,占48.26%。经潜在类别分析分为健康行为组(37.68%)、读写疲劳组(42.64%)和视屏疲劳及饮食不良组(19.68%)3个行为生活方式潜在类别,近视率分别为79.22%、88.38%和86.73%。其中,读写疲劳组和视屏疲劳及饮食不良组以中度近视为主,健康行为组以轻度近视为主。与健康行为组比较,读写疲劳组(OR=1.996,95%CI:1.454~2.739)、视屏疲劳及饮食不良组(OR=1.715,95%CI:1.157~2.543)的近视风险较高。结论读写时间长、运动和睡眠不足、视屏时间长、含糖饮料和油炸食物摄入频率高可能增加鄞州区中小学生近视风险,可针对不同行为生活方式类别人群制定干预方案。Objective To examine the effect of lifestyle behaviors on myopia among primary and middle school students in Yinzhou District,Ningbo City using latent class analysis,so as to provide insights into prevention of myopia among primary and middle school students.Methods A total of 1547 students were sampled from primary and middle schools in Yinzhou District using a stratified cluster sampling method.Myopia-associated lifestyle behaviors were collect-ed using questionnaires,and visual acuity was tested.Myopia-associated lifestyle behaviors were subjected to latent class analysis among primary and middle school students,and the association between lifestyle behaviors and risk of my-opia was examined using a logistic regression model.Results A total of 1547 questionnaires were allocated,and 1494 valid questionnaires were recovered,with an effective recovery rate of 96.57%.There were 247 primary school students(16.53%),452 junior high school students(30.25%),532 senior high school students(35.61%)and 263 voca-tional high school students(17.60%),and 773 men(51.74%)and 721 women(48.26%).Latent class analysis showed that students'lifestyle behaviors were classified into three groups,including the healthy behavior group(37.68%),read-ing and writing fatigue group(42.64%),and video fatigue and poor diet group(19.68%),with myopia prevalence of 79.22%,88.38%and 86.73%,respectively.Moderate myopia was predominant in the reading and writing fatigue group and video fatigue and poor diet group,and low myopia was predominant in the healthy behavior group.A higher risk of myopia was found in the reading and writing fatigue group(OR=1.996,95%CI:1.454-2.739)and video fatigue and poor diet group(OR=1.715,95%CI:1.157-2.543)than in the healthy behavior group.Conclusions Long reading and writing duration,insufficient exercise and sleep,long video watching duration,and high intake frequency of sugary drinks and fried foods may increase the risk of myopia in primary and middle school students in Yinzhou District.Tar-geted myopia intervention
