To investigate the prevalence of and risk factors for age-related maculopathy (ARM) in three racial/ethnic groups : non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans.
A nationally representative population-based, cross-sectional study.
A total of 8270 persons 40 years of age or older, a sample of the Third National Health and Nutrition Examination Survey.
Age-related maculopathy was determined by the grading of fundus photographs using a standardized protocol.
The prevalence of any ARM in the civilian noninstitutionalized United States population including those 40 years of age or older was 9.4% (95% confidence interval [Cl], 8.2,10.6) as estimated from the sample.
After adjusting for age, there was no difference in the prevalence of early ARM (defined largely by the presence of soft drusen) by ethnic/racial group.
However, for the less frequent component lesions of early ARM (increased retinal pigment and retinal pigment epithelial depigmentation), the odds ratios (95% Cls) comparing non-Hispanic blacks to non-Hispanic whites were 0.47 (0.31,0.74) and 0.59 (0.33,1.04), respectively, and for comparing Mexican-Americans to non-Hispanic whites, they were 0.41 (0.21,0.81) and 0.72 (0.44,1.19), respectively.
For late ARM, the odds ratio (95% Cl) for non-Hispanic blacks compared to non-Hispanic whites was 0.34 (0.10,1.18) and for Mexican-Americans compared to non-Hispanic whites, it was 0. (...)
