title: [Human papillomavirus infection, a possible biological marker of sexual behavior among university students].
abstract: OBJECTIVE
  To estimate the prevalence of Human papillomavirus (HPV) among university students and to use it as a biological marker to assess sexual behavior.
  
  
  METHODS
  A cross-sectional study was carried out between 2000 and 2001 among 194 students at Universidad Autónoma del Estado de Morelos, Mexico. A data collection instrument was applied and genital samples were taken to detect oncogenic HPV DNA. Data were analyzed using the chi-squared test and odds ratios.
  
  
  RESULTS
  Overall HPV prevalence was 14.4%. Women who had had two or more sexual partners during the previous year showed a greater risk of HPV infection (OR 6.0, 95% CI 1.7-21.1), as did women who had used oral contraceptives and spermicides at their latest intercourse (OR 3.0, 95% CI 1.0-8.7). Males who consumed cocaine were at a greater risk of HPV infection (OR 7.6, 95% CI 1.3-45.1).
  
  
  CONCLUSIONS
  HPV prevalence is relatively high. HPV is a reliable biological marker of sexual behavior among females. A greater sample size may be needed to assess its reliability among men.
