Résumé
Objectives: Antiretroviral treatment (ART) scale-up in sub-Saharan Africa has made it possible to investigate the maintenance of adherence to HIV medications. We describe here adherence to ART and identify its correlates in the Cameroonian context.Design: Prospective cohort study in 9 rural district hospitals. Methods:A mixed logistic regression model was used to identify factors associated with adherence to ART in 401 patients with data prospectively collected on adherence.Results: Although 73% of patients were adherent after the first month on ART, this proportion decreased to 61% after 24 months. After adjustment for known factors of adherence to ART (such as knowledge, motivation and side-effects), patients who reported willingness to start ART before initiation, those who were satisfied with information provided by their physicians, and those who implemented reminder methods for ART intake {eg, using an alarm clock, mobile phone, or watch [odds ratio (95% confidence interval)] = 2.45 (1.58 to 3.79), but also the help of a relative to remind them or other methods} were more likely to be adherent to ART. Conclusions:Besides highlighting some correlates already known to have an impact on adherence to ART, our findings also underline the need to reinforce the counseling component of follow-up through innovative methods. Accordingly, training and implementation research should encourage the use of medication reminder methods, such as mobile phones, to assure adherence over time and improve long-term response to ART.
