The study purpose was to determine the association between sexual debut and HIV sero-status, and factors contributing to a positive HIV sero-status.  Retrospective cross-sectional data from the Kenya Demographic and Health Survey-2003 were used.  Data on women aged 15-49 (n=3,273) and men aged 15-54 (n=2,917) accepting HIV testing were retained from three datasets.  Stata version 10.1 was used for analyses, p<0.05.  Nine percent of women and 5% of men tested positive for HIV, of whom 46% and 49%, p<0.001 were aged 16-21 respectively.  After adjusting for confounding, women and men who had sexual debut aged 16-21 were 2.31 (95% CI: 1.52-3.51), p<0.001 and 1.83 (95% CI: 1.07-3.13), p<0.05 times more likely to test positive for HIV compared to those who never had sex respectively.  Early sexual debut continues to be a major risk factor for acquiring HIV infection later in life, suggesting earlier interventions could have a major impact towards fighting the disease.  (Afr J Reprod Health 2013; 17[2]: 46-57).


Le but de l'étude était de déterminer l'association entre l'activité sexuelle et situation sérologique du VIH et les facteurs qui contribuent à un effet positif de la situation  sérologique du VIH.   Nous nous sommes servis  des données transversales rétrospectives de l'Enquête démographique et de santé au Kenya -2003.  Les données sur les femmes âgées de 15-49 ans (n = 3273) et les hommes âges de 15-54 ans (n = 2917) qui ont accepte le dépistage du VIH ont été retenus à partir de trois ensembles de données. La version Stata 10.1 a été utilisé pour les analyses, p <0,05.  Les analyses ont révélé la présence du VIH chez neuf pour cent des femmes et 5% des hommes,  dont 46% et 49%, p <0,001 étaient âgés de 16 à 21 ans respectivement. Après l’ajustement pour les facteurs confondants, les femmes et les hommes qui ont eu leurs premiers rapports sexuels a l’âge de 16 à 21 ans  étaient 2,31 (IC à 95%: 1,52 à 3,51), p <0,001 et 1,83 (IC à 95%: 1.7 à 3.13), p <0,05 fois plus susceptibles d’avoir le résultat positif dans les analyses pour déterminer la présence du VIH par rapport à ceux qui n'ont jamais eu des rapports sexuels, respectivement. L'initiation au rapport sexuel précoce continue d'être un facteur de risque majeur de contracter l'infection du VIH plus tard dans la vie, ce qui suggère que les interventions antérieures pourraient avoir un impact majeur vers  la lutte contre la maladie.
