In sub-Saharan Africa, where people living with HIV are frequently stigmatized, the intake of antiretroviral treatment (ART) remains a critical issue for many patients. Although the secret intake of ART may hinder the adherence to treatment, data on its specific impact on therapeutic effectiveness are lacking. We therefore assessed the association between secret intake of ART (i.e., hidden from family) and HIV-1 viremia among patients treated in a public routine clinic in Burkina Faso. We performed a cross-sectional study from December 2012 to September 2013 among patients on ART at the Day Care Unit in Bobo Dioulasso. Patients were eligible for the study if they were 15 years old or over, infected with HIV-1 or HIV-1+2, and on ART for at least six months. HIV-1 viral load was measured using Biocentric or Abbott Real Time assay. Study-specific data were collected by social workers using face-to-face interviews, and medical data using the routine electronic database. The association between secret intake of ART and viral load >300 copies/mL was assessed using a multivariate logistic regression. Of 771 patients (women 81.4%; median age 41 years; median time on ART 51 months), 408 reported secret intake of ART and 363 declared open intake. Compared to the latter, patients who hid their intake were younger, more likely to be women and to be involved in a polygamist or in a non-cohabiting union. Viremia was observed in 4.4% of patients hiding ART intake and 9.4% of those taking it openly. By multivariate analysis, secret intake of ART was significantly associated with a lower risk of viremia (adjusted odds ratio 0.41, 95% confidence interval 0.22-0.76). The unexpected relation between secret intake of ART and viremia found in this study requires further investigations. Quantitative and qualitative studies need to be performed.
