Unique Identifier : AIDSLINE ICA10/94370051 AB OBJECTIVE: To determine HIV-1 seroprevalence and risk factors for HIV infection among men entering the Royal Thai Army (RTA). METHODS: Each year about 60,000 21 year-old men are conscripted into the RTA. Selection is by lottery and enlistment is in May and Nov. Since Nov 89 all conscripts have been screened for HIV-1 Ab. From Nov 91 to May 93 demographic data were also collected on 118,761 men. RESULTS: The nationwide seroprevalence increased from 0.5% in Nov 89 to 4.0% in May 93. In each year prevalence varied by area of residence. The prevalence in May 93 was: Upper North (UN) = 11.7%; Lower North (LN) = 2.7%; Central (C) = 3.9%; Bangkok Metropolitan Administration (BMA) = 3.7%; Northeast (NE) = 2.2%; and South (S) = 2.3%. The largest increases between 1991 and 1993 were in S (1.3% to 2.3%) and LN (1.8% to 2.7%). Overall, compared with men from other areas, those from the UN had the highest risk of infection (RR = 4.50, p < .001). Unmarried men had higher prevalence than did married men, 3.7% vs 2.7% (p < .001). Residence in a provincial capital was associated with higher prevalence (4.6%) compared with urban areas (4.1%), BMA (3.5%), or rural areas (3.1%). Prevalence was higher among those with < 10 years of education (3.6% vs 2.6%, p < .001). CONCLUSIONS: Since 1989, the prevalence of HIV has increased in RTA conscripts. Although the prevalence is highest in the UN, the largest relative increase has occurred in other areas. HIV prevention must be directed at all areas of the country.
