Abstract

Purpose : To determine the burden of uncorrected refractive error (UCRE) and the risk factors associated with UCRE in a population-based sample of African American adults.

Methods : A population-based sample of self-identified African Americans 40 years of age and older (n = 6347) from thirty contiguous census tracts in Inglewood, California, underwent a complete ophthalmic examination and an in-home-administered questionnaire to assess sociodemographic (e.g. marital status, employment status, education level, annual income level), lifestyle (e.g. smoking history), and biological and medical (e.g. weight and height, health and vision insurance, healthcare and eye care utilization) risk factors associated with UCRE. UCRE was defined as a ≥ 2-line improvement with refraction in the better seeing eye. Sex- and age-specific burden of UCRE were calculated and multiple regression analyses were used to identify independent risk factors.

Results : Of the 7957 eligible participants in AFEDS, 6347 (80%) completed both the in-home interview and the clinical examination. The overall prevalence of UCRE was 14.6% (n = 925). The prevalence of UCRE was higher for men than for women (15.9% and 13.8%, respectively, P = 0.02). There was no significant age-related trend in the burden of UCRE (P > 0.05). Annual household income of less than $20,000 and lack of vision care insurance were significant independent risk indicators for UCRE.

Conclusions : Our data confirm the high burden of UCRE in African Americans making it the leading cause of visual impairment in this population. Providing universal coverage for vision care and prescription lenses or glasses is an affordable and achievable health care intervention that would reduce the burden of visual impairment in African American adults and help improve vision health in this vulnerable minority population.
