HIV risk behavior and testing among MS M in Bangkok 2015-2019: a short report.

Men who have sex with men (MSM) in Thailand have high HIV prevalence. This analysis used three years of data from the Behavioral Surveillance Survey (BSS) to examine the behaviors and biomedical interventions among MSM in Bangkok. Percent MSM with an HIV or STI test in the past 12 months decreased from 50.8% to 29.8%, and 42.2% to 33.0%, respectively. The frequency of HIV/STI testing was higher among those who had university-level education, as well as among those who reported higher AIDS knowledge, and had utilized prevention services. Additionally, awareness of PrEP peaked in 2017 (74.1%). The study found an increasing trend of men who had sex without a condom the last time they had anal sex with a man, and/or with multiple partners. Nearly two-thirds of the sample were reached by HIV prevention interventions. One-third had correct AIDS knowledge. These findings suggest that, after an increase of sex behavior risk, a decrease in PrEP awareness, and unknown HIV status, HIV prevalence among MSM in Bangkok may have begun to increase again. Intensified prevention interventions are urgently needed to reduce HIV behavioral risk for MSM since that is a major driver of the HIV epidemic in Thailand.

Adverse Childhood Experiences and Prevalence of Cigarette and E-Cigarette Use Among Adolescents in Bangkok, Thailand.

Currently, e-cigarettes are the most popular tobacco product among adolescents. The purpose of this study was to explore the relationship between exposure to adverse childhood experiences (ACEs) and use of cigarettes, e-cigarettes, and dual use in a sample of adolescents in Bangkok, Thailand. The sample comprises 6167 students from 48 schools (grades 9, 11, and vocational year 2) who participated in the 2019 round of the Behavior Surveillance Survey. History of 11 ACEs was used to calculate a cumulative ACE score (range 0-11). Multinomial logistic regression was used to assess the relationship between history of ACEs and smoking. In the sample, 7.0% reported using e-cigarettes only and 9.5% used e-cigarettes and cigarettes (dual use). After controlling for sociodemographic characteristics, history of ACEs was associated with increased odds of dual use. The odds of cigarette, e-cigarette, and dual use was significantly greater if the adolescent had a history of ≥4 ACEs. Special attention is needed to prevent smoking of different types among those with a history of ACEs.
