Diabetes-Related Cardiovascular and All-Cause Mortality in Asian American Subgroups.

ABSTRACT

Background: Asian Americans experience heterogeneity in cardiovascular risk factors and cardiovascular disease, with a particularly high burden of diabetes in several Asian subgroups. Objectives: The objectives of this study were to quantify diabetes-related mortality in Asian American subgroups and compare this with Hispanic, non-Hispanic Black, and non-Hispanic White individuals. Methods: Using national-level vital statistics data and concurrent population estimates, age-standardized mortality rates and proportional mortality from diabetes-related mortality were calculated for non-Hispanic Asian (and subgroups Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese), Hispanic, non-Hispanic Black, and non-Hispanic White populations in the United States, 2018-2021. Results: Diabetes-related deaths numbered 45,249 in non-Hispanic Asian, 159,279 in Hispanic, 209,281 in non-Hispanic Black, and 904,067 in non-Hispanic White individuals. Among Asian Americans, age-standardized mortality rates of diabetes-related mortality with cardiovascular disease as underlying cause ranged from 10.8 (95% CI 9.9-11.6) per 100,000 in Japanese females to 19.9 (95% CI 18.9-20.9) per 100,000 in Filipina females, and from 15.3 (95% CI 13.9-16.8) per 100,000 in Korean males to 37.8 (95% CI 36.1-39.5) per 100,000 in Filipino males. The proportion of all deaths related to diabetes was higher in all Asian subgroups (9.7%-16.4% for females; 11.8%-19.2% for males) compared with non-Hispanic Whites (8.5% for females; 10.7% for males). The highest proportion of diabetes-related deaths occurred in Filipino adults. Conclusions: There was an approximately 2-fold variation in diabetes-related mortality among Asian American subgroups, with Filipino adults experiencing the greatest burden. All Asian subgroups experienced higher proportional mortality for diabetes-related mortality compared with non-Hispanic White individuals.
