[Alternative medicine, beliefs, and management of people with HIV in Gabon].

BACKGROUND
According to WHO, 80% of the population in Africa has used alternative medicine for primary health care at least once. Gabon continues to have a high prevalence of HIV, estimated in 2011 at 5.2%. Overall, 22 253 PLWHA (people living with HIV/AIDS) - adults and children - are being treated, including 9976 on ARVs (antiretroviral drugs). The procedures for ARV initiation are very long, ARVs are frequently out of stock, and treatment in care centers for PLWHA is stigmatized: all these factors favor the development of alternative medicine for HIV care in Gabon.


OBJECTIVE
To analyze the impact of alternative medicine in the treatment of PLWHA in Gabon.


METHODOLOGY
This cross-sectional survey was conducted during a total of four months between May 2009 and September 2010 among PLWHA older than 18 years who had been receiving ARVs for at least 6 months and consented to participate (7 centers) and among physicians and other caregivers of these centers (8 centers). We used a simple random sample method. Epidata software was used for data collection, and the analyses were performed with SAS™ software.


RESULTS
Of the 5752 patients on ARVs followed at the 7 study sites, 422 PLWHA were interviewed (58.3% of them women): 284 (67.29%) in Libreville and 138 (38.7) in the provinces. Christians accounted for 90.5% (including 21.5% from Protestant evangelical churches), and Muslins for 5.68%, while 4% stated that they had no religion. 12.5% of doctors referred their patients to religious or spiritual groups.


CONCLUSION
Our study showed that half of PLWHA did not know the procedures for access to ARV treatment and that beliefs about HIV/AIDS differed strongly according to place of residence. Finally, the cultural context related to alternative medicine is very present in the PLWHA treatment settings in Gabon. Although PLWHAs have easy access to ARVs, their association with organized and controlled alternative medicine can be beneficial.
