Immigration and obesity among lower income blacks.

OBJECTIVE

Our objective was to examine the associations of nativity, immigrant generation, and language acculturation with obesity among lower income black adult men and women.

METHODS

Data from 551 black adult men and women were collected from participants in the Healthy Directions-Health Centers Study. Race/ethnicity and nativity were self-reported. Language acculturation was defined using participants' first language, preferred reading language, and language spoken at home. Mixed model logistic regression models were estimated to account for within-health center clustering.

RESULTS

Foreign-born blacks had a lower obesity risk, compared with all U.S.-born participants, in multivariable analyses [odds ratio (OR) = 0.57, 95% confidence interval (CI), 0.38, 0.84]. Among U.S.-born participants, those with foreign-born parents were significantly less likely to be obese than individuals with U.S.-born parents (OR = 0.54; 95% CI, 0.37, 0.80). Low-moderate language acculturation also decreased the odds of being obese (OR = 0.45; 95% CI, 0.23, 0.88).

CONCLUSIONS

Our findings suggest a protective effect of foreign-born status and low-moderate language acculturation on obesity risk among lower income black immigrants. These data highlight the importance of more frequently examining nativity in obesity-related research conducted among blacks.
