title: Sexually transmitted diseases and risk behaviors among California farmworkers: results from a population-based survey.
abstract: BACKGROUND
  The prevalence of sexually transmitted diseases and associated risk behaviors among California farmworkers is not well described.
  
  
  OBJECTIVE
  To estimate the prevalence of sexually transmitted diseases (STDs) and associated risk behaviors among California farmworkers.
  
  
  METHODS
  Cross-sectional analysis of population-based survey data from 6 California agricultural regions was performed for participants tested for Chlamydia trachomatis (CT), Neisseria gonorrhea (GC), and syphilis, and who completed an interviewer-administered behavioral risk factor survey.
  
  
  RESULTS
  Among the 403 males and 234 females examined and interviewed, males (29.3%) were more likely than females (9.6%) to have had 2 or more sex partners in the past 5 years. Forty-two percent of males ever had sex with a commercial sex worker; unmarried males were more likely than married males to report sex with a commercial sex worker in the past 2 years. Twelve percent of males and 5% of females reported ever having had an STD. Most participants did not report any methods to protect against STDs. Of 192 males and 178 females tested for CT, 3 males and no females were positive. No cases of GC were found. Of 387 males and 194 females tested for syphilis, 4 males and 1 female had positive rapid plasma reagin (RPR) and Treponema pallidum particle agglutination (TPPA) results.
  
  
  CONCLUSIONS
  In this population-based survey among agricultural workers, there was low STD prevalence but high prevalence of sexual risk behaviors, particularly among males.
