description: <p>Importance: Acculturation among Hispanic/Latino populations, defined as adaptation to US lifestyle and culture, is often assumed to lead to adverse health outcomes that will reduce the immigrant health advantage. Objective: To evaluate the risks for incident diabetes and hypertension by levels of acculturation and educational attainment. Design, Setting, and Participants: This study used data from the Hispanic Community Health Study/Study of Latinos, a population-based cohort study of men and women aged 18 to 74 years who identified as Central American, Cuban, Dominican, Mexican, Puerto Rican, or South American living in 4 urban locales in the US. Visit 1 spanned March 2008 to June 2011; visit 2 spanned October 2014 to December 2017. Main Outcomes and Measures: Multivariable logistic regression was used to evaluate the association between language acculturation level defined by the Short Acculturation Scale for Hispanics (SASH) and educational attainment (less than high school graduate vs more than high school) and incident diabetes and hypertension by heritage group. Results: Of 11 623 adult participants, 1207 (10.4%) were of Central American heritage, 1645 (14.2%) of Cuban heritage, 1021 (8.8%) of Dominican heritage, 11 623 (41.3%) of Mexican heritage, 1801 (15.5%) of Puerto Rican heritage, and 795 (6.8%) of South American heritage. The mean (SE) age of all participants was 43.1 (0.3) years, and 7345 (56.3%) were female. A total of 8697 (71.4%) were born outside the US, 4358 (32.5%) had less than a high school education, and 7475 (58.3%) were less acculturated (SASH score less than 2). Incident rates of diabetes (total cohort, 14.6% [95% CI, 13.6%-15.6%]) and hypertension (total cohort, 20.4% [95% CI, 19.0%-21.9%]) varied across heritages; Mexican individuals (17.2% [95% CI, 15.5%-19.0%]) had the highest diabetes incidence and Dominican individuals the highest hypertension incidence (27.1% [95% CI, 22.7%-31.4%]). Persons with more educational attainment were at lower risk for diabetes and hypertension independent of acculturation, and more acculturated participants had a lower risk for incident diabetes. Less acculturated with lower socioeconomic status (SES) were more likely to have incident diabetes (weighted predicted probability [WPP], 0.17 [95% CI, 0.14-0.19]), and more acculturated with lower SES had the highest predicted probability of hypertension (WPP, 0.19 [95% CI, 0.15-0.23]). More acculturated with higher SES were at lower risk of diabetes (WPP, 0.11 [95% CI, 0.09-0.13]) and had a lower predicted probability of hypertension (WPP, 0.10 [95% CI, 0.08-0.12]). Conclusions and Relevance: In this cohort study, the association of acculturation with health outcomes is not unidirectional and interacts with educational attainment in determining incident diabetes and hypertension. The Hispanic and Latino paradox, in which immigrants have a health advantage, is influenced by more factors than acculturation and may persist with higher educational attainment. These observations may inform prevention and treatment strategies associated with cardiometabolic health in Hispanic/Latino populations.</p>
