背景:为了调查新疆7-19岁学生散光的患病率和危险因素,中国。
方法:以学校为基础,对新疆接受屈光检查的学生进行了横断面研究,中国,2019年5月至12月。确定散光的患病率。散光定义为圆柱功率(C)≤-0.75D,未定义散光≤-1.50D,和高散光为C≤-3.00D。散光类型为:违规散光(主要子午线在180°±30°的最大屈光度),规则散光(主子午线在90°±30°的最大折射),和斜散光(所有其他情况下)。
结果:在接受检查的71,838名学生中(51.0%的男孩,7-19岁),25,945(36.1%,95CI:35.52-36.68%)有散光和1267(1.8%,95CI:1.07-2.53%)散光高。与回族(34.0%)相比,汉族个体的散光患病率更高(39.6%),哈萨克(34.0%),吉尔吉斯斯坦(32.1%),维吾尔族(26.4%)。在25,945名散光学生中,19,947有正常散光(76.9%),3405有违规散光(13.1%),和2593有斜散光(10.0%)。多变量logistic回归分析显示,种族(汉族个体更易感),男性,年龄,屈光不正(近视和远视)与散光独立相关,高散光,和规则散光(均P<0.05)。
结论:新疆儿童青少年散光患病率为36.1%,包括1.8%的高散光。在这个人群中,散光主要是规则散光类型(76.9%)。汉族,男性,近视或远视与散光的高风险独立相关。
BACKGROUND: To investigate the prevalence and risk factors for astigmatism in 7-19-year-old students in Xinjiang, China.
METHODS: A school-based, cross-sectional
study was conducted on students who underwent refraction examination in Xinjiang, China, between May and December 2019. The prevalence of astigmatism was determined.
Astigmatism was defined as cylinder power (C) ≤-0.75 D, undefined
astigmatism as ≤-1.50 D, and high
astigmatism as C ≤-3.00 D. Astigmatism types were: against-the-rule astigmatism (maximum refraction of the main meridian in 180° ± 30°), with-the-rule astigmatism (maximum refraction of the main meridian at 90°±30°), and oblique
astigmatism (all other cases).
RESULTS: Of the 71,838 students examined (51.0% boys, 7 - 19 years old), 25,945 (36.1%, 95%CI: 35.52-36.68%) had astigmatism and 1267 (1.8%, 95%CI: 1.07-2.53%) had high astigmatism. The prevalence of astigmatism was greater in Han individuals (39.6%) compared with the Hui (34.0%), Kazakh (34.0%), Kyrgyz (32.1%), and Uyghur (26.4%) populations. Among the 25,945 students with astigmatism, 19,947 had with-the-rule astigmatism (76.9%), 3405 had against-the-rule
astigmatism (13.1%), and 2593 had oblique
astigmatism (10.0%). Multivariable logistic regression analysis showed that ethnicity (Han individuals more susceptible), male gender, age, and refractive errors (myopia and hyperopia) were independently associated with astigmatism, high
astigmatism, and with-the-rule
astigmatism (all P < 0.05).
CONCLUSIONS: The prevalence of astigmatism among children and adolescents in Xinjiang was 36.1%, including 1.8% of high astigmatism. In this population, astigmatism was mainly of the with-the-rule astigmatism type (76.9%). Han ethnicity, male gender, and myopia or hyperopia were independently associated with a high risk of astigmatism.
