Older immigrants perceived health after migration to the United States: Influence of age and level of acculturation

Objectives: To determine the age-related differences in the association between level of acculturation and perceptions about change in health status after migration in mid- to late-life immigrants.

Design: Cross-sectional study.

Setting: Nationally representative cohort of legal U.S. immigrants.

Participants: Legal immigrants ≥50 years of age.

Measurements: The outcome was perceived change in health status, determined by the survey question, "compared with your health right before you most recently came to the United States to live, would you say that your health is better now, about the same or worse?" The main predictor included age group (50-64, 65-74, and ≥75 years) and secondary variable of interest was level of acculturation. Analyses were adjusted for demographic characteristics, medical, and functional comorbidities.

Results: Immigrants age ≥75 years were more likely to report worse health after migration [RRR 1.93, 95% CI (1.17, 3.17), p < 0.01] compared with immigrants of 50-64 years, but this difference was not statistically significant in the adjusted model. Acculturation level was associated with increased likelihood of reporting worse health status, [RRR 2.10, (1.02, 4.35), p < 0.05] for somewhat acculturated and [RRR 2.55, (1.10, 5.88), p < 0.05] for most acculturated, compared with participants who were not acculturated.

Conclusion: The oldest immigrant group (≥75 years) was more likely to report worse health after migration, but this association was no longer significant after accounting for acculturation level and other covariates. Future work should be undertaken to identify specific health needs across older immigrant age groups and identify acculturative stressors that negatively impact health.
