Late HIV diagnosis among immigrants in Spain vs. native-born Spaniards, 2010-15.

ABSTRACT

BACKGROUND: In 2012, the central government of Spain enacted Royal Decree-Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012, which abolished universal healthcare coverage, thus limiting access to care for undocumented immigrants. Free health care was also no longer granted to anyone who has never been employed. In this context, this study investigated the prevalence of late HIV diagnoses (LHDs) among immigrants living in Spain vs. native-born Spaniards. METHODS: Data (n = 5943) from the 2010 to 2015 Cohort of the Spanish AIDs Research Network were used, including HIV-positive and antiretroviral therapy (ART)-naïve patients throughout Spain. Multivariate logistic models were fitted to compare the prevalence of LHD among the groups, adjusting for covariates. RESULTS: The prevalence of LHD in the total sample was 39.5%. Compared with native-born Spaniards (n = 4445), immigrants (n = 1488) were more likely to have LHD (37.4% vs. 45.7%, respectively; P < 0.001). Multivariate analysis showed that the prevalence ratio of LHD among immigrants vs. native-born Spaniards was 1.15 [95% confidence interval (CI), 1.02-1.28], after adjusting for covariates. This disparity widened from 2010 to 2011 (APR = 1.14, 95% CI, 1.02-1.29) to 2012-15 (APR = 1.28, 95% CI, 1.17-1.39), although the change was not statistically significant. CONCLUSIONS: Immigrants in Spain had a higher risk of LHD compared with native-born counterparts. LHD is an important healthcare marker due to the positive benefits of early HIV diagnosis, including prevention, improvements in health outcomes and decreases in overall cost of treatment. More research is needed on the causes of the disparity and potential social and policy interventions to reduce the prevalence of LHD among immigrants.
