title: Identification of novel risks for nonulcerative sexually transmitted infections among young men in Kisumu, Kenya.
abstract: OBJECTIVE
  STI prevention interventions often aim to reduce HIV incidence. Understanding STI risks may lead to more effective HIV prevention.
  
  
  OBJECTIVE
  To identify STI risks among men aged 18-24 in Kisumu, Kenya.
  
  
  METHODS
  We analyzed baseline data from a randomized trial of male circumcision. Participants were interviewed for sociodemographic and behavioral risks. Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) were diagnosed by polymerase chain reaction assay and Trichomonas vaginalis (TV) by culture. The outcome for logistic regression analysis was infection with NG, CT, or TV.
  
  
  RESULTS
  Among 2743 men, 214 (7.8%; 95% CI: 6.8%-8.8%) were infected with any STI. In multivariable analysis, statistically significant risks for infection were: living one's whole life in Kisumu (OR = 1.50; 95% CI: 1.12-2.01), preferring "dry" sex (OR = 1.47; 95% CI: 1.05-2.07), HSV-2 seropositivity (OR = 1.37; 95% CI: 1.01-1.86), and inability to ejaculate during sex (OR = 2.04; 95% CI: 1.15-3.62). Risk decreased with increasing age and education, and cleaning one's penis less than 1 hour after sex (OR = 0.51; 95% CI: 0.33-0.80).
  
  
  CONCLUSIONS
  Understanding how postcoital cleaning, "dry" sex, and sexual dysfunction relate to STI acquisition may improve STI and HIV prevention.
