Abstract：
UNASSIGNED: Astigmatism is closely associated with myopia progression, vision loss, eye fatigue and amblyopia, which seriously endangers children\'s eye health. This study aims to investigate the prevalence and characteristic distribution of astigmatism in children in Langzhong City, providing valuable insights for allocating resources and develop prevention and control strategies.
UNASSIGNED: A cross-sectional study and random sampling survey were conducted. Between January and November 2021, 21,415 students aged 5 to 13 years from 14 primary schools in Langzhong City underwent non-cycloplegic refractive testing using autorefraction. The data on myopia were analyzed using SPSS (Statistical Package for the Social Sciences) version 23.0.
UNASSIGNED: The inclusion criterion was set at an absolute astigmatism value of ≥0.50D. Among the 21,415 children studied, 61.70% were found to have astigmatism. The prevalence of astigmatism varied significantly across different grades (χ2=501.414, P<0.001). The predominant types of astigmatism were mild astigmatism (0.50-1.00D) and with-the-rule astigmatism. Mixed astigmatism was primarily observed in children in grades 1 and 2, while compound myopic astigmatism was more common in children in grades 3 to 6. These differences were statistically significant. As the degree of astigmatism increased, the proportions of against-the-rule astigmatism, oblique astigmatism, compound myopic astigmatism, and simple hyperopic astigmatism decreased, whereas the proportions of with-the-rule astigmatism, mixed astigmatism, and compound hyperopic astigmatism increased.
UNASSIGNED: The prevalence of astigmatism among school-age children aged 5 to 13 years in northeast Sichuan is notably high, with compound myopic astigmatism and with-the-rule astigmatism being the most common types. Regular refractive examinations are crucial for the early detection and management of astigmatism.

摘要：
■散光与近视进展密切相关，视力丧失,眼睛疲劳和弱视，严重危害儿童的眼睛健康。本研究旨在调查陇中市儿童散光的患病率及分布特征。为分配资源和制定预防和控制策略提供有价值的见解。
■进行了横断面研究和随机抽样调查。在2021年1月至11月期间，来自lang中市14所小学的21,415名5至13岁的学生使用自动屈光进行了非睫状肌麻痹屈光测试。使用SPSS（社会科学统计软件包）23.0版分析近视数据。
■纳入标准设置为绝对散光值≥0.50D。在研究的21,415名儿童中，61.70％的人发现有散光。不同等级的散光患病率差异显著(χ2=501.414,P<0.001)。散光的主要类型是轻度散光（0.50-1.00D）和规则散光。混合散光主要在1级和2级儿童中观察到，而复合近视散光在3至6级儿童中更为常见。这些差异具有统计学意义。随着散光程度的增加，违规散光的比例，斜散光，复合性近视散光,单纯远视散光减少，而正常散光的比例，混合散光,复合远视散光增加。
■川东北5~13岁学龄儿童散光患病率明显较高,复合近视散光和规则散光是最常见的类型。定期的屈光检查对于早期发现和治疗散光至关重要。
