中小学生视力减退是常见病之一,为了了解当地青少年的视力情况:我站于1984年曾对旗内东升庙(1285人)和炭窑口硫铁矿(1485人)二地中小学生共2740人(男1397、女1343,中学生1111人,小学生1629人)进行了4种常见病的调查。其中对视力减退的原因及发病规律进行了分析、报告。采用国际标准视力表,被试者站在距表5米处自然光条件下测试。视力小于1.0者为视力减退,而且每人一双眼为一个统计患病的指标,然后进行比较。两地的视力减退发现率为12.48%。男女比发病率为7.73:17.42,有显著差异(X~2=58.98 P<0.01)。中小学生比为21.87:6.08,差异也非常显著(X~2=50.85 P<0.01)。两地比较则无差异(X~2=2.78 P>0.05)。
The primary and secondary school students’ vision loss is one of the most common diseases. In order to understand the sight of local young people, I stood in 1984 for 2740 primary and secondary school students in the flagship Dongshengmiao (1285 people) and charcoal kiln mouth pyrite (1485 people) People (male 1397, female 1343, 1111 middle school students, primary school students 1629 people) conducted a survey of four common diseases. Among them, the causes and the pathogenesis of vision loss were analyzed and reported. The use of international standard visual acuity chart, subjects were standing 5 meters from the table at natural light conditions test. Visual acuity of less than 1.0 were visually impaired, and each binocular for a statistical indicators of illness, and then compared. The prevalence of vision loss in both places was 12.48%. The odds ratio between men and women was 7.73: 17.42, with significant difference (X ~ 2 = 58.98 P <0.01). The ratio of primary and secondary students was 21.87: 6.08, and the difference was also significant (X ~ 2 = 50.85 P <0.01). There was no difference between the two places (X ~ 2 = 2.78 P> 0.05).
