Disparities of Subjective Cognitive Decline Among Native Hawaiians/Other Pacific Islanders, Asian Americans, and White Americans in Hawai'i: Behavioral Risk Factor Surveillance System 2015 and 2017

Abstract

Existing research on subjective cognitive decline (SCD) among Native Hawaiians/Other Pacific Islanders (NHOPIs) is limited even though NHOPI adults have the highest prevalence of cardiovascular risk factors. In this study, we investigated SCD disparities among NHOPIs, Asian Americans, and White Americans and its contributing factors utilizing the 2015 and 2017 survey year data from the Behavioral Risk Factor Surveillance System (BRFSS) for Hawai'i State in the United States. The SCD prevalence was 11.9%, 8.97%, and 7.86% among NHOPIs, Whites, and Asians, respectively. Adjusting for sociodemographic and health behavioral variables, the prevalence ratios (PRs) of SCD were 1.37 (95% confidence interval [CI] = 1.05-1.78) for NHOPI versus Asian and 1.15 (95% CI = 0.89-1.50) for NHOPI versus Whites. The associations were weakened after adjusting for health conditions. Depressive disorders, coronary heart disease or myocardial infarction, stroke, and diabetes were associated with cognitive decline in the multivariate-adjusted model. NHOPIs experienced more SCD-related functional difficulties than other races.
