摘要
目的了解广州市大、中、小学生视力不良和户外(阳光下)活动时间现状及关系,为学生视力不良防控和干预提供有针对性的科学依据。方法于2017年9—12月根据2017年《全国学生常见病及健康危险因素监测工作手册》要求,采用分层整群随机抽样法在广州市选取1个城区(8所学校)和1个郊区(5所学校)共2908名学生进行视力监测和问卷调查。结果广州市学生视力不良率为69.2%,女生(74.4%)>男生(64.2%),城区(76.3%)>郊区(54.1%),大学(95.0%)>职高(82.5%)>高中(81.1%)>初中(73.4%)>小学(45.6%)。除小学外,各组学生重度视力不良人数均最多。每天户外活动时间<1h、<2h报告率均为女生>男生,城区>郊区,大学和高中较高。每天户外活动时间<2h的学生视力不良率(72.3%)高于≥2h的学生(65.6%)。控制混杂因素后,每天户外活动时间<2h的学生发生视力不良的风险是≥2h学生的1.24倍(95%CI=1.04~1.48)。结论广州市学生视力不良率较高,程度以重度为主并趋于低龄化,户外活动时间不足。女生、城区学生和初中阶段应作为视力不良防控的重点。
Objective To investigate the association of poor vision with time spent in outdoor activity among students from primary and middle schools,as well as from universities in Guangzhou,so as to provide targeted scientific basis for prevention and control of low vision.Methods According to the requirements of National Monitoring of Common Diseases and Health Risk Factors among Students Manual,a total of 2 908 students were selected in 1 urban area and 1 suburban county for monitoring and investigation in Guangzhou.Results The poor vision rate was 69.2%among students in Guangzhou,with girls(74.4%)>boys(64.2%),suburban country(76.3%)>urban areas(54.1%),university(95.0%)>vocational high school(82.5%)>regular high school(81.1%)>junior high school(73.4%)>primary school(45.6%).With the exception of primary students,the severe poor vision has the largest proportion in each age group.The proportion of spending less than 1 or 2 h for outdoor activities per day:girls>boys,suburban country>urban area,university and regular high school are higher.The poor vision rate of students who spent<2 h(72.3%)for outdoor activities daily was higher than those spent≥2 h(65.6%).Compared with students who spent≥2 h/d for outdoor activities,those spent<2 h/d were at 1.24 times risk of being low vision(OR=1.24,95%CI=1.04-1.48),controlling for the available confounders.Conclusion Poor vision rate of students in Guangzhou is high,occurring mainly with severe impairment and in younger age,the daily outdoor activity time is low.Girls,students from suburban country and junior high school should be considered as the emphasis for prevention and control of low vision.
