The Association of Duration of Residence in the United States with Cardiovascular Disease Risk Factors Among South Asian Immigrants

South Asians are disproportionately impacted by cardiovascular disease (CVD). Our objective was to examine the association between duration of residence in the US and CVD risk factors among South Asian adult immigrants. Multivariate logistic regression analyses using pooled data from the 2005, 2007, 2009 California Health Interview Surveys. Duration of residence in the US <15 years was significantly associated with overweight/obese BMI (OR 0.59; 95 % CI 0.35, 0.98 for 5 to <10 years), daily consumption of 5+  servings of fruits/vegetables (OR 0.37; 95 % CI 0.15, 0.94 for 10 to <15 years), and sedentary lifestyle (OR 2.11; 95 % CI 1.17, 3.81 for 10 to <15 years) compared with duration of residence ≥15 years after adjusting for illness burden, healthcare access, and socio-demographic characteristics. Duration of residence was not significantly associated with other CVD risk factors. Duration of residence is an important correlate of overweight/obesity and other risk factors among South Asian immigrants.
