■近视是全球范围内的重大公共卫生问题。本研究旨在探讨两个典型地区儿童和青少年近视患病率及相关因素的地区差异。甘南藏族自治州(简称甘南州,一个藏族居住区)和甘肃省武威市(一个汉族居住区),中国,为区域近视的防控提供参考。
■这项研究是对甘肃省儿童和青少年的横断面研究,中国。采用分层整群抽样方法抽取学生6187人(武威市:3266人,甘南藏族自治州:2921人)。对参与者进行眼科检查和问卷调查。近视被定义为当眼调节放松时眼睛的球面等效屈光度小于或等于-0.50D的情况。采用χ2检验和多因素logistic回归分析近视的相关因素。
■6187名学生的近视率为71.4%,武威市学生近视率(77.5%)高于甘南州(64.6%)(p<0.001)。多因素分析结果显示,武威市女生(比值比(OR)=1.325),低年级学生(OR=2.542),高年级学生(OR=4.605),眼睛和书本之间的距离小于一英尺(OR=1.291),和近视的父母(一个,OR=2.437;二,OR=4.453)有更高的近视风险(所有,p<0.05)。对于甘南州来说,女孩(OR=1.477),高年级学生(OR=1.537),每天做作业的时间≥2小时(OR=1.420),眼睛和书之间的距离小于一英尺(OR=1.205),平均连续用眼时间(0.25-<0.5h,OR=1.345,0.5-<1小时,OR=1.317,≥1小时,OR=1.313),平均每日睡眠时间<8小时(OR=1.399),和近视的父母(一个,OR=1.852;二,OR=2.913)有更高的近视风险(所有,p<0.05)。
■甘肃省近视患病率处于较高水平。近视的患病率和危险因素因地区而异。
UNASSIGNED: Myopia is a significant public health problem across the globe. This study aimed to examine the regional disparity in prevalence and correlated factors of myopia in children and adolescents in two typical regions, Gannan Tibetan Autonomous Prefecture (Gannan Prefecture for short, a Tibetan residential area) and Wuwei City (a Han residential area) in Gansu Province,
China, and to provide a reference for the prevention and control of regional myopia.
UNASSIGNED: The study was a cross-sectional study of children and adolescents in Gansu Province,
China. A total of 6,187 (Wuwei City: 3,266, Gannan Tibetan Autonomous Prefecture: 2,921) students were selected by stratified cluster sampling. Eye examinations and questionnaires were administered to the participants. Myopia is defined as a condition in which the spherical equivalent refractive error of an eye is less than or equal to -0.50 D when ocular accommodation is relaxed. The χ2 test and multivariate logistic regression analysis were used to analyze the correlated factors of myopia.
UNASSIGNED: The myopia rate of 6,187 students was 71.4%, and students had a higher rate of myopia (77.5%) in Wuwei City compared to Gannan Prefecture (64.6%) (p < 0.001). The results of multivariate analysis in Wuwei City showed that girls (odds ratio (OR) = 1.325), junior students (OR = 2.542), senior students(OR = 4.605), distance between eyes and book less than one foot (OR = 1.291), and parents with myopia (one, OR = 2.437; two, OR = 4.453) had higher risks of myopia (all, p < 0.05). For Gannan Prefecture, girls (OR = 1.477), senior students (OR = 1.537), daily time spent doing homework ≥2 h (OR = 1.420), the distance between eyes and book less than one foot (OR = 1.205), mean time continuous eye use (0.25-<0.5 h, OR = 1.345, 0.5-<1 h, OR = 1.317, ≥1 h, OR = 1.313), average daily sleep duration <8 h (OR = 1.399), and parents with myopia (one, OR = 1.852; two, OR = 2.913) had higher risks of myopia (all, p < 0.05).
UNASSIGNED: The prevalence of myopia is at a relatively high level in Gansu Province. The prevalence and risk factors for myopia vary by region.
