This study aimed to determine the prevalence and severity of vision impairment by race in the United States by analyzing the population-based prevalence of corrected distance visual acuities in non-Hispanic Whites, Hispanics, and African Americans.
This is a nationally representative, population-based, cross-sectional study. Data from the National Health and Nutrition Examination Survey (NHANES) 2001-2002 were analyzed to investigate the epidemiologic features of corrected distance visual acuities among non-Hispanic Whites (n = 3034), Hispanic Americans (n = 1532), and African Americans (n = 1183) aged 18-85 years.
Prevalence rates of overall impairment were 5.0%, 2.1%, and 1.6% for non-Hispanic Whites, Hispanic Americans, and African Americans, respectively (P = .1015).
The prevalence of vision impairment based on corrected distance visual acuity is higher in non-Hispanic Whites than in Hispanic and African Americans. The magnitude of this racial difference is not statistically significant and is less than that of previous studies that were based on comparisons of uncorrected visual acuities.
本研究旨在通过分析非西班牙裔白人、西班牙裔和非裔美国人基于人群的矫正远视力患病率，来确定美国不同种族视力损害的患病率和严重程度。
这是一项具有全国代表性的基于人群的横断面研究。分析了2001 - 2002年国家健康与营养检查调查（NHANES）的数据，以调查18 - 85岁非西班牙裔白人（n = 3034）、西班牙裔美国人（n = 1532）和非裔美国人（n = 1183）中矫正远视力的流行病学特征。
非西班牙裔白人、西班牙裔美国人和非裔美国人的总体视力损害患病率分别为5.0%、2.1%和1.6%（P = 0.1015）。
基于矫正远视力的视力损害患病率在非西班牙裔白人中高于西班牙裔和非裔美国人。这种种族差异的幅度在统计学上不显著，且小于以往基于未矫正视力比较的研究。
