Abstract 12144: Heterogeneity Between Rates of Hypertension Among Immigrant and U.S.-born Blacks: Pooled NHANES, 2003-2014 Data
Introduction: Epidemiological data suggest that Blacks in the U.S. experience the highest prevalence of hypertension (44%) worldwide. It is unclear, however, if there are differences between U.S.-born and foreign-born immigrant Blacks. Since the passage of the Immigration and Nationality Act of 1965, a growing proportion of the U.S. Black population is made up of Black immigrants and it is predicted that by 2060, 16.5% of U.S. Blacks will be immigrants. Within the Black population, there are pronounced cultural differences in food preferences and physical activity habits, as well as social experiences, which are important risk factors for hypertension.
Methods: Pooled NHANES data (2003-2014) for non-Hispanic immigrant Black adults aged 22-79y (n=515) and their US-born counterparts (n=4,249) were analyzed. Multivariable-adjusted logistic regression was used to investigate the association between nativity and odds for hypertension (defined as diagnosed hypertension, use of medication, or measured blood pressure ≥140/90mmHg). We also examined the association between length of U.S. residency among Black immigrants and hypertension.
Results: Nearly half (48%) of US-born Blacks and 31% of immigrant Blacks had hypertension. Black immigrants were 42.4% less likely (OR 0.58, 95% CI 0.46, 0.72) to have hypertension than their U.S.-born counterparts. Length of U.S. residency was not associated with hypertension among Black immigrants.
Conclusions: The likelihood of hypertension differs for immigrants versus U.S.-born Blacks. Considering place of birth among U.S. Blacks in epidemiological and public health research studies may help accurately characterize health disparities and develop targeted interventions to effectively address hypertension in this population.
