Abstract 10477: Acculturation is Associated with Left Ventricular Mass in a Multiethnic Sample: The Multi-ethnic Study of Atherosclerosis
Increased left ventricular mass (LVM), is an independent risk factor for cardiovascular disease events, and varies between race/ethnic groups. Acculturation is the adoption of the traditions, values, and cultural practices of a host country and may involve stress-related processes as well as behavioral change. The relation between acculturation and LVM has not been explored.
Methods: These analyses include 5,004 men and women, free of clinical cardiovascular disease, who were white, African American, Hispanic and Chinese and completed the cardiac MRI assessment. LVM was evaluated as a continuous measurement, indexed by body surface area. Acculturation was characterized based on language spoken at home, place of birth and time in the US, and a summary acculturation score ranging from 0 = least acculturated to 5 = most acculturated. Unadjusted and adjusted means were compared across acculturation levels.
Results: In analyses pooling all ethnic groups and adjusted for age, gender, serum creatinine, smoking status, physical activity, diabetes status, and systolic blood pressure, speaking English at home (β=1.22, SE=0.46, p=0.03) and increasing percent life in the U.S. (β=3.92, SE=1.35, p=0.004) were associated with higher LVM; least number of years living in the US (β=-2.16, SE=1.03, p=0.04) and a lower acculturation score were protective of increased LVM (β=-1.79, SE=1.03, p=0.002). Associations of acculturation with LVM varied somewhat across ethnic groups. For Hispanics, English language spoken at home (β=2.64, SE=0.99, p=0.02); for blacks, not being born in the US (β=3.21, SE=1.36, p=0.02); and for Chinese, increasing percent life in the US (β=5.5, SE=2.42, p=0.02) were all associated with higher LVM.
Conclusions: Greater acculturation is associated with increasing LVM in a multiethnic sample. The impact of the acculturative process on cardiovascular health needs to be further appreciated.
