[HIV and risk factors for the blood donors at the central hospital of Yaounde, Cameroon].

The HIV/AIDS infection is in a permanent progress in Cameroon. Through this descriptive and analytical cross-sectional study, we aimed to compare the occurrence of the HIV by taking into account the risks factors that are significantly associated with HIV. The investigation was carried out from 1 January till 31 December 2009 in the Blood Bank of the Central Hospital of Yaounde in Cameroon. A structured questionnaire was proposed to collect socio-demographic and risk behavioral information. Venous blood was collected for HIV antibody testing. Generalized estimating equation with logistic regression was used to analyze the risk factors for HIV infection. In all, 5 058 persons were included in this study. Serological examination revealed a total prevalence of 5.4% of HIV infection in the population studied. The family/replacement donors constituted the majority (69.5%) and showed a higher risk of seropositivity of HIV than the benevolent donors in raw analysis; but after adjustment, the family donors had the same risk of seropositivity of HIV than voluntary blood donors (aOR = 1.00). Variables such as homosexual intercourse (aOR = 1.61), to have already made a screening test of HIV (aOR = 1.83), mobility (aOR = 2.24), treatment and records of STI (aOR = 3.81), use of the condom (aOR = 6.63), more than one sexual partner (aOR = 8.40) remained significantly linked to the result of the HIV serology and constituted risk factors that will be emphasized during the selection of the donors.
