目的：报告研究人群屈光不正的基线患病率。设计：一项来自4个民族儿童屈光不正与眼部发育的多中心纵向观察研究。患者和方法：研究人群包括1至8年级（5-17岁）的2523名儿童（534名非裔美国人，491名亚洲人，463名西班牙裔和1035名白人）。近视定义为每条主经络的屈光度为-0.75 D或以上，远视定义为+1.25 D或以上，散光定义为两条主经络之间至少相差1.00 D（单眼麻痹性自屈光）。结果：近视占9.2%，远视占12.8%，散光占28.4%。屈光不正患病率作为种族的函数有显著差异(chi(2)， P
Objective: To report the baseline prevalence of refractive error in the study population.Design: A multicenter, longitudinal, observational study of refractive error and ocular development in children from 4 ethnic groups.Patients and Methods: The study population included 25 23 children (534 African American, 491 Asian, 463 Hispanic, and 1035 white) in grades 1 to 8 (age, 5-17 years). Myopia was defined as -0.75 diopters (D) or more and hyperopia as +1.25 D or more in each principal meridian, and astigmatism was defined as at least a 1.00-D difference between the 2 principal meridians (cycloplegic autorefraction).Results: Overall, 9.2% of the children were myopic, 12.8% were hyperopic, and 28.4% were astigmatic. There were significant differences in the refractive error prevalences as a function of ethnicity (chi(2), P
