Risk factors for HIV infection among Thai laborers during 1992-1993.
From June 1992 to May 1993, 39,939 Thai men attended the clinic for laborers going abroad at Siriraj Hospital in Bangkok for a pre-assignment physical exam and mandatory blood screen for HIV and syphylis. Of this total, 438 tested positive for HIV antibody (1.1%). Of these, 215 men returned for post test interview and physical exam and were compared with 1,348 men randomly selected HIV-1 seronegative men. None of the HIV-1 seropositive had a history of injecting drug use or had received blood transfusion in the past seven years. HIV-1 seropositivity was associated with the TPHA serological marker for syphylis > 1.160 (p = 0.015, odd ratio 1.8), history of urethritis (p = 0.009, odd ratio 1.92) (Table 4). This study found that HIV-1 seropositive men were mostly single, were likely to be from the rural northern provinces of Thailand or Bangkok. History of purchase of low-fee commercial sex and less condom use were significantly associated with HIV-1 seropositivity as was a history of STD in the year prior to interview. Information on HIV disease and pre-test/post test counselling is needed for Thai laborers who are applying for work abroad to countries which require HIV and syphylis screening. In this effort, the Ministry of Labor and Social Welfare, the Ministry of Public Health and the clinic for laborers going abroad should join forces to provide this service. This will serve to increase awareness and self-determination among an increasingly vulnerable segment of the population who also have the potential to spread HIV infection to their spouse and other sex partners.(ABSTRACT TRUNCATED AT 250 WORDS)
