Sexually transmitted diseases and sexual lifestyles of long-distance truck drivers: a clinico-epidemiologic study in south India.

Our study objective was to determine the prevalence and pattern of sexually transmitted diseases (STDs) and to study sexual lifestyles of long-distance truck drivers and their assistants in south India. For this, a total of 263 truck drivers/assistants were recruited from the highway clinic from October 1999 to March 2001. All of them were sexually active and heterosexual contact was the predominant mode (99.2%). Two-thirds of them had contact with commercial sex workers (CSWs) and roughly 60% admitted alcohol consumption. One hundred and two participants (38.7%) had various STDs. The positivity rates of HIV, VDRL and HBsAg were 15.9%, 13.3% and 21.2% respectively. The higher median age, education less than primary school level, longer duration of occupation, longer duration of each trip and a previous history of genital ulcer disease were significant risk factors for the acquisition of HIV infection.
