Abstract
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. 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. 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). 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.

Independent risk factors associated with HIV infection among the total study population included being single, having no formal education (AOR 6.5, 95% confidence intervals (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)
The marked decline in the human immunodeficiency virus (HIV) epidemic in Thailand has been attributed to identifying and controlling its associated behavioral risk factors. [1, 2] It was estimated that 440,000 people are living with HIV or Acquired Immunodeficiency Syndrome (AIDS) in Thailand at the end of 2017 as compared with 570,000 at the end of 2005
