To identify ethnic differences in the prevalence of ocular diseases (non-traumatic) in obese patients over age 65.
Inpatients ≥65 years of age and diagnosed with ≥1 non-traumatic ocular disease between 2012-2014 were identified from the National Inpatient Sample (NIS), a nationally representative database of US hospitalizations. Demographics, ethnicity, duration and cost of hospital stay, comorbidities, and insurance status were recorded. Chi-squared analysis was used to calculate the prevalence of ocular disorders in obese vs. non-obese patients for each ethnic group using p<0.05 as being significant. Cases were defined as obese patients with ocular diseases; the age and sex-matched control group consisted of non-obese patients with ocular diseases. The ratio of cases to controls was 1 to 5. The primary outcome was the prevalence of ocular disorders.
1,160,400 inpatients with non-traumatic ocular diseases were identified in the 3-year period; 193,615 (16.7%) were obese and had complete racial demographic information for categorization as non-Hispanic White, Hispanic, African American, Asian/Pacific-Islander, or Native American. With respect to ethnicity, prevalence of the following ocular diseases was higher in obese than non-obese patients: diabetic retinopathy (DR) in all ethnicities, ocular hypertension (OHTN) in all except Native Americans (p<0.03); primary open-angle glaucoma (POAG) in all except Asian/Pacific-Islanders (p< 0.001); age related macular degeneration (AMD) in all except non-Hispanic Whites (P<0.001); retinal vein occlusion (RVO) only among non-Hispanic Whites (P<0.001); retinal artery occlusion (RAO) in all except African Americans (p<0.002). Across all ethnicities, obese patients were more likely than non-obese patients to have hypertension (p<0.001), hyperlipidemia (p<0.001), and diabetes mellitus with or without chronic complications (p<0.001). Among all obese patients, POAG was most prevalent in African Americans, DR was most prevalent in Asian/Pacific-Islanders and Native Americans, and AMD and RAO were most prevalent in Non-Hispanic Whites.
Within most ethnic groups, higher prevalence of DR, OHTN, POAG, AMD, RVO and RAO was found among obese adults ≥ 65 years old compared to non-obese controls. Within this NIS inpatient cohort, significant ethnic disparities were observed in the prevalence of ocular diseases in obese elderly patients.
