Prevalence and Risk Factors of Self-reported Vision Impairment among Native Hawaiians and Pacific Islanders in the United States

Racial disparities in vision impairment have been reported among Black, Hispanic, and White Americans. However, there is a paucity of research on vision impairment among Native Hawaiians and Pacific Islanders (NHPIs). The objective of this study was to determine the prevalence of, and risk factors for, self-reported visual impairment in NHPI adults in the United States (US). Data from the NHPI and 2014 National Health Interview Surveys were analyzed using sample weights and variance estimates. Prevalence was calculated for vision impairment and blindness for the NHPI and overall US populations. Sociodemographic and clinical risk factors of vision impairment were explored using descriptive statistics, χ² tests, and simple and multiple logistic regression. In total, 2 586 NHPIs and 36 673 individuals in the US were included. The prevalence of vision impairment was 8.8% among NHPIs and 9.1% for the overall US population, and the prevalence of blindness was 0.72% for NHPIs and 0.35% for the overall population. Independent risk factors associated with vision impairment were having a Charlson Comorbidity Index over 1 [OR: 2.89, 95% CI: (1.42–5.88)] and having a family income below $35 000 [OR: 2.03, 95% CI: (1.06–3.89)]. In summary, the rate of blindness is higher among NHPIs than the overall US population, especially for older and unemployed individuals with more comorbidities. Higher comorbidity burden, lower family income, and recent eye care were risk factors for vision impairment. More research is necessary to develop targeted and culturally sensitive interventions to promote NHPI eye health.
