ObjectiveTo examine inequalities in self-rated health between immigrant and native populations in 2014 and 2020, and whether these inequalities vary by sex/gender and social support.MethodsThis cross-sectional study used information from adults aged ≥18 years who participated in the European Health Interview Survey in Spain in 2014 and 2020. Self-rated health was specified as good or bad/poor. Immigration status and length of stay were considered to specify the exposure. Poisson regression was used to estimate prevalence ratios (PR) and 95% confidence intervals (CI) in each survey. Interaction terms between immigration status and survey; and immigration status, survey, and sex/gender or social support were tested.ResultsThe adjusted analyses showed that when compared with Spanish native adults, immigrants with 6-15 years residing in Spain had a 1.34 (95%CI:1.18, 1.53) greater probability of rating their health as bad/poor in 2014. This probability was 1.48 (95%CI:1.28, 1.75) in 2020. No heterogeneity was observed for the associations of immigrant status/length of stay with self-rated health for sex/gender or social support in either survey (p-interactions for sex/gender: 0.41 and social support: 0.71).ConclusionGiven the growth of the immigrant population in Spain and the importance of immigration as a social determinant of health, these findings call attention to a deeper examination of inequalities, with the aim of identifying potential factors leading to bad/poor rating of health over time.Copyright © 2024 Elsevier Inc.
