Abstract

Abstract : Objectives: To analyse the effect of educational level on the progression from HIV seroconversion to highly active antiretroviral therapy (HAART) requirement, HAART initiation, AIDS and death from any cause at different periods of the HIV epidemic in Spain. Methods: Open, prospective, multicentre cohort of HIV seroconverters set up in 1983. The risk of progression was calculated by the multiple decrements method. Effect of educational level was estimated by Fine and Gray model, adjusting for sex, HIV transmission category, age and method to estimate seroconversion. Calendar period was introduced as a variable that could change over time (<1997; 1997–2003; >2003). Results: Up to 2009, 989 HIV seroconverters with information on educational level were identified. Some 52% and 48% had a low and a high educational level respectively. Persons with higher education had 32% lower risk of death (HR: 0.68; 95% CI 0.45 to 1.03). Regarding progression to AIDS, educational level had no effect in the pre-HAART era (HR: 1.47; 95% CI 0.91 to 2.38), but did show an effect in the period 1997–2003 (HR: 0.58; 95% CI 0.34 to 0.99), which was accentuated after 2004 (HR: 0.26; 95% CI 0.10 to 0.68). No difference was found in time to HAART requirement or initiation. Conclusions: Results suggest that, despite similar access to HAART, persons with low educational level are at increased risk of HIV disease progression, highlighting the impact of social inequities on health. The availability of more effective treatments over time will strengthen the protective effect of higher education on the development of AIDS.
