Acculturation and Hypertension Diagnoses Among Hispanics in California.

Background: Among U.S. Hispanic immigrants and all other Hispanics living in the USA, heart disease is the leading cause of death. Meanwhile, the prevalence of hypertension among Mexican Americans, a subgroup of the U.S. Hispanic population, is rising. The purpose of this study was to estimate the prevalence of hypertension diagnosis and to determine the association between acculturation and hypertension among Mexican Americans and Other Hispanics in California.

Methods: Using data from the 2014 California Health Interview Survey (CHIS), we performed multivariable logistic regression to identify whether acculturation (measured by self-reported duration of U.S. residence) predicted hypertension diagnoses, after controlling for sociodemographic characteristics (e.g., age, gender, poverty level), body mass index, health insurance coverage, and cigarette smoking.

Results: Of 3793 Hispanics who participated in the survey, 81.8% were Mexican Americans, and 18.2% were Other Hispanics. The prevalence of hypertension among Hispanics was 24.0% (95% CI: 21.5-26.7), which was lower than that of African Americans (40.3%, 95% CI 34.2-46.7) and Whites (31.8%, 95% CI: 29.7-34.0). In the multivariable regression analysis, acculturation was associated with hypertension for Mexican Americans (aOR = 1.71, 95% CI, 1.24-2.36) and Other Hispanics (aOR = 2.77, 95% CI, 1.71-4.51).

Conclusion: The results show a positive association between acculturation in the USA and hypertension diagnoses among Mexican Americans and Other Hispanics. The findings can help public health practitioners, medical providers, policymakers, and others better understand the potential influences of acculturation on Hispanic immigrants' health and inform the creation of culturally sensitive health promotion materials.
