Association of American Identity with Cardiovascular Health in South Asian Americans: The MASALA Study
Keywords:American identity, South Asian, Immigrant, Cardiovascular health
Background: Ethnic and national identity may influence cardiovascular health (CVH)-related behaviors, such as dietary preference. To better understand how acculturation is related to CVH among South Asian American adults, we evaluated the association of self-rated American identity with CVH factors among participants of the MASALA (Mediators of Atherosclerosis in South Asians Living in America) Study.
Methods: Multivariable linear regression quantified the associations of self-rated American identity (1 [low American identity] to 10 [high American identity]) with CVH factors, including measures of cholesterol, blood pressure, and blood glucose. The role of diet quality, physical activity, and social support in mediating these associations was evaluated.
Results: Participants (n=771) lived in the US for an average 27 (SD 11) years. Mean self-rated American identity score was 5.5 (2.4). After adjustment, a 5-point higher American identity score was associated with 6.5 mg/dL higher low density lipoprotein cholesterol, 6.6 mg/dL higher total cholesterol, 2.9 mmHg higher systolic blood pressure, and 1.4 mmHg higher diastolic blood pressure. Accounting for diet quality, physical activity, or social support did not alter these associations.
Conclusions: Higher self-rated American identity is associated with worse CVH factors among South Asian American adults.
