Risk Factors for HIV Infection among Young Thai Men during 2005-2009.

ABSTRACT: Thailand is one of several countries with a continuing generalized HIV epidemic. We evaluated the risk factors for HIV prevalence among 17-29 year old men conscripted by a random process into the Royal Thai Army (RTA) in 8 cohorts from 2005-2009.A series of case-cohort studies were conducted among the male RTA conscripts who had been tested for HIV seroprevalence after they were inducted. Men who were HIV positive were compared with a systematic random sample (1 in 30-40) of men from the total population of new conscripts. Each subject completed a detailed risk factor questionnaire.A total of 240,039 young Thai men were conscripted into the RTA and were screened for HIV seroprevalence between November 2005 and May 2009. Of 1,208 (0.5%) HIV positive cases, 584 (48.3%) men were enrolled into the study. There were 7,396 men who were enrolled as a comparison group. Among conscripts who had an education lower than a college-level, the independent risk factors for HIV infection were age in years (AOR 1.38, 95% CI 1.28-1.48), a history of sex with another man (AOR 3.73, 95% CI 2.70-5.13), HCV infection (AOR 3.89, 95% CI 2.56-5.90), and a history of sex with a female sex worker (FSW) (AOR 1.35, 95% CI 1.10-1.66). Among conscripts who had a college degree, the independent risk factor for HIV infection was a history of sex with another man (AOR 23.04, 95% CI 10.23-51.90). Numbers of sexual partners increased and the age at first sex, as well as the use of condoms for sex with a FSW decreased in successive cohorts.The HIV seroprevalence among cohorts of 17-29 years old men has remained at about 0.5% overall during 2005-2009. The most significant behavior associated with HIV prevalence was a history of sex with another man. Our data indicate continuing acquisition of HIV among young men in Thailand in recent years, especially among men with a history of same sex behavior.

Project description:INTRODUCTION:Understanding the current epidemiology of human immunodeficiency virus (HIV) infection in Thailand will facilitate more effective national HIV prevention programs. This study aimed to determine the prevalence and risk factors for HIV infection among young Thai men. METHODS:A total survey was conducted of Royal Thai Army new conscripts, participating in the national HIV surveillance in November 2010 and May 2011. Behavioral risk factors for HIV infection were determined using a standardized survey questionnaire in the total study population and men who have sex with men (MSM) subgroup. RESULTS:A total of 301 (0.5%) HIV infected young Thai men were identified from the total study population (63,667). Independent risk factors associated with HIV infection among the total study population included being single (adjusted Odds Ratio [AOR] 1.6, 95% Confidence Interval [CI] 1.1-2.2), having no formal education (AOR 6.5, 95% CI 2.3-18.4) or a bachelor's degree (AOR 1. 8, 95% CI 1.0-3.0), engaging in bisexual (AOR 3.7, 95% CI 2.4-5. 6) or exclusively homosexual activity (AOR 14.4, 95% CI 10.4-19.8), having a history of Sexually Transmitted Infection (STI) (AOR 2.3, 95% CI 1.6-3.3) and having sex in exchange for gifts/money (AOR 2.0, 95% CI 1. 5-2.8). A total of 4,594 (7.9%) MSM were identified, of which 121 (2.6%) were HIV infected. The prevalence of HIV infection among MSM in urban (2.8%) and rural (2.4%) areas were relatively comparable (p-value = 0.44). Of the identified MSM, 82.5% reported having sexual desire with females only. Risk factors associated with HIV infection in the MSM subgroup included living in the western region (AOR 3.5, 95% CI 1.2-10.4), having a bachelor's degree (AOR 2.7, 95% CI 1.2-5.7), having a history of exclusive receptive (AOR 3.6, 95% CI 1.6-7.7) or versatile anal sex (AOR 4.7, 95% CI 3.0-7.5) and history of having sex in exchange for gifts/money (AOR 2.3, 95% CI 1.5-3.5). CONCLUSION:The prevalence of HIV infection among young Thai men has continued to be below 0.5% in 2010 and 2011. High risk sexual activity, including MSM, played a major role in the HIV epidemic among this population. Effective HIV prevention programs should cover MSM who have heterosexual desire as well as having sex in exchange for gifts/money and be implemented in both urban and rural areas.
