The American Heart Association recently added healthy sleep to its metrics used to define ideal cardiovascular health. Little is known about the association between sleep and CVD prevalence among Asian subgroups. Hypothesis: The association between suboptimal sleep duration and CVD risk prevalence will differ by Asian American subgroup. Methods: We analyzed results from the National Health Interview Survey (2012-2018, N=234,126), a nationally representative sample. Participants (age>40 years old) included 214,956 non-Hispanic Whites (NHWs), 3,043 Asian Indians, 3,993 Chinese, 4,719 Filipinos, and 7,603 other Asians. Suboptimal sleep was self-reported and defined as <7 or >9 hours. CVD was defined as self-reported stroke, heart attack, coronary artery disease, or angina. We used multivariable logistic regression models to ascertain the association. All analyses included complex survey design considerations. Results: Suboptimal sleep duration was associated with higher CVD prevalence for NHWs and all Asians, but in Asian subgroup stratified analyses, suboptimal sleep was only associated with higher CVD prevalence among Other Asians. Conclusions: Our results show heterogeneity in the association between sleep duration and CVD prevalence among Asian subgroups, however further research is needed to better understand these relationships.
