摘　　要：目的了解上海市小学生散光状态，分析其相关影响因素，为小学生散光的防治提供流行病学依据。方法采取横断面研究方法。选取上海市闸北区和田路小学2011年5月所有在校学生为样本进行调查，所有调查对象均进行屈光度、裸眼视力、眼轴长度及角膜曲率检查，了解其散光情况，并通过分析各因素与散光度数的关系了解与散光发病相关的因素。结果入选调查对象465人，实际调查460人（920眼），调查率98．92％。散光患病率为58．26％，散光度数为（-0．57±0．68）D；在近视复合散光和远视复合散光各亚型中，顺规散光的患病率最高，占68．68％。8～〈9岁组散光患病率最低，为47．09％，≥11岁组散光患病率最高，为73．21％。散光度无性别差异（P=0．817）。近视组儿童散光度为（-0．64±0．70）D，较非近视组的（-0．52±0．67）D高（P=0．005），且散光常与离焦伴随发生，离焦越严重，散光程度越大。散光与球镜度数、角膜散光、身高及体质量呈正相关，相关系数分别为0．279、0．745、0．102及0．132（均为P〈0．05），而与年龄、身体质量指数及眼轴长度无显著相关性。结论上海市和田路小学小学生中散光患病率较高，以顺规散光为主。近视儿童散光程度较非近视儿重高，散光度与球锖屈井．废、角膜散光。身高、体质量有关。Objective To asses the astigmatism status and its related factors of pupils in Shanghai, and provide the epidemiological evidences for better control of astig- matism of pupils. Methods In May 2011, all the in-school students of Hetian Road pri- mary school in Zhabei area, Shanghai were chose as sample and cross-sectional method was employed. Refraction, uncorrected visual acuity, axial length and corneal curvature were detected,the astigmatism status was described and the relationship between astig- matism status and related factors was analyzed by analyzing the relationship between those factors and astigmatism. Results Among 465 pupils in school,460 objects （920 eyes） involved in this investigation and the rate was 98.92%. The incidence rate of a- stigmatism was 58.26% , and the astigmatism degree was （ - 0.57 _＋ 0.68 ） D; The pre- dominant astigmatic subtype was the with-the-rnle astigmatism （68.68%）. The inci- dence of astigmatism was lowest in the pupils aged from 8 years to 9 years, which was 47.09% ,highest in the pupils aged equal to or more than ll years,which was 73.21%. There was no difference of cylindrical diopter between different genders （ P = 0. 817 ）. More astigmatic cases appeared in the myopic group （P = 0.005 ）, and the diopter of a- stigmatksm was positively correlated with the degree of defocus. The prevalence of astig- matism was positively correlated with spherical diopter, corneal astigmatism, height and weight（ all P 〈 0.05 ）, and the correlation coefficient was 0.279,0. 745,0. 102 and 0. 132, respectively, but not correlated with age, weight mass index and ocular length. Conclu- sion The astigmatic status of Hetian Road primary school in Zhabei area show that the incidence of astigmatism is high, and the predominant subtype ks with-the-rule astig- matism. The incidence rate of astigmatism in myopic group is higher than that in stigma- tism group, and the prevalence of astigmatism is correlated with spherical diopter, cor- neal astigmatism, height and weight
