【摘要】：目的分析2014年云南省中小学生视力不良的流行现况及其影响因素,为制定学生近视防治策略与措施提供参考。方法采用多阶段分层随机整群抽样的方法,抽取云南省7个州(市)9~18岁中小学生,用对数视力表和屈光串镜结合法筛查其视力;利用非条件Logistic回归分析,分析中小学生视力不良的流行现况及影响因素。结果云南省中小学生的视力不良检出率为48.51%,标化率为47.30%。多因素非条件logistic回归分析发现,影响视力的主要因素有地区的社会经济发展水平、民族、平均每天的睡眠时间、平均每天做作业的时间、年龄、每周食用鸡蛋的次数、每天食用牛奶的次数、平均每天看电视的时间和性别(P值均0.05)。随着社会经济发展水平的提高、每天做作业时间的增加和年龄的增长,中小学生发生视力不良的风险也随之升高;随着每天睡眠时间的增加、每天食用牛奶、每周食用鸡蛋3次及以上和每天花一定时间看电视,中小学生发生视力不良的风险也随之降低。女生发生视力不良的风险高于男生,少数民族是中小学生视力不良的保护因素。结论云南省中小学生视力不良防控形势依然严峻。应进一步加强开展预防视力不良的宣传教育,采取针对性措施,以实现降低视力不良发生的目标。
[Abstract]:Objective to analyze the prevalence of visual impairment in primary and secondary school students in Yunnan province in 2014 and its influencing factors so as to provide a reference for formulating strategies and measures for the prevention and treatment of myopia. Methods Multi-stage stratified random cluster sampling was used. The visual acuity was screened by logarithmic visual acuity table (LVA) combined with diopter string microscope in 18 year old primary and middle school students in 7 counties (cities) of Yunnan province. Non-conditional Logistic regression analysis was used to analyze the prevalence and influencing factors of poor eyesight in primary and middle school students. Results the detection rate of visual impairment in primary and middle school students in Yunnan Province was 48.51%. The standardized rate was 47.30.Multivariate conditional logistic regression analysis showed that the main factors affecting visual acuity were the level of social and economic development of the region, the nationality, and the average daily sleep time. The average amount of time you do your homework, your age, the number of eggs you eat each week, and the number of times you eat milk every day. The average daily TV watching time and gender P value are 0.05. With the improvement of the level of social and economic development, the daily homework time and the increase of age. The risk of poor vision of primary and middle school students also increased; With the increase in daily sleep time, eat milk every day, eat eggs three times a week and more and spend a certain amount of time watching TV every day. The risk of poor eyesight of primary and middle school students is also reduced. The risk of girls suffering from poor eyesight is higher than that of boys. The minority nationality is the protective factor of poor eyesight of primary and middle school students. Conclusion the situation of prevention and control of poor eyesight of primary and middle school students in Yunnan Province is still grim. We should further strengthen publicity and education to prevent poor eyesight and take targeted measures. In order to achieve the goal of reducing the incidence of poor vision.
