Background: Herpessimplex virus type-2 HSV-2 and human papillomavirus HPV are common sexuallytransmitted infections STIs among fishing communities and are associated withhigh HIV prevalence in this underserved population.
However, there is limitedknowledge on HIV incidence among fishermen.
This study aimed at determiningprevalence, incidence and risk factors associated with HIV infection amongfishermen in Kisumu Kenya.
Methods: Three hundred fishermen were evaluated for baselineHIV, HSV-2, HPV infection and a structured questionnaire administered.
HIVincidence was assessed after 12 months among those initially HIV negative.
HIVincidence rate in person-years and prevalence were estimated.
Multivariatelogistic regression was used to determine factors independently associated withHIV acquisition.
Results: HIV prevalence was 23.3% 95% CI: 18.5 - 28.1.
Riskfactors for baseline HIV prevalence were older age aOR = 2.13; 95% CI: 1.25 -5.07, history of STI aOR 4.21; 95% CI: 2.07 - 9.34, baseline HPV infectionaOR 2.13; 95% CI: 1.05 - 4.77, number of lifetime sexual partners >5 aOR= 5.76 95% CI: 1.41 - 13.57 and transactional sex aOR = 10.98; 95% CI: 1.86 -19.34.
Condom uses with new sexual partner aOR 0.21, 95% CI: 0.08 - 0.55 andduring most recent sexual act aOR 0.09, 95% CI: 0.03 - 0.61, were negativelyassociated with HIV prevalence.
HIV incidence was 4.2 95% CI = 1.3 - 7.1 per100 person-years with being single aIRR = 8.32; 95% CI: 1.27 - 54.67 as anindependent risk factor.
Condom use with new sexual partner aIRR = 0.11; 95% CI:0.01 - 0.89 and recent sex with wife-regular girlfriend compared to sexworker-casual partner; aIRR = 0.03; 95% CI: 0.01 - 0.35 were associated withreduced risk of HIV acquisition.
Conclusion: Inconsistent condom use andtransactional-casual sexual partnerships were the main high-risk sexualbehaviors in addition to marital status explaining the high HIV acquisitionrate among fishermen.
Intensified safer sex promotion is urgently needed inthis subpopulation to avert new HIV infections.
