Abstract
BACKGROUND: Pre-exposure prophylaxis (PrEP) is an HIV prevention strategy that involves administering antiretroviral medication to individuals who are not yet infected with the virus, particularly among men who have sex with men (MSM), a high-risk population. Continuous monitoring of PrEP usage behaviors is essential.
OBJECTIVE: To examine the characteristics and usage behaviors of PrEP among MSM in Chiang Rai province.
METHODS: This descriptive cross-sectional study collected data from 188 participants between
1 August to 31 October 2024 using a snowball sampling technique. Data were gathered through
a questionnaire validated for content and reliability (CVI=0.94, Cronbach’s Alpha=0.92). Descriptive statistics, including frequencies and percentages, were used to analyze general information,
PrEP usage characteristics, and behaviors.
RESULTS: Among the participants, 140 individuals (74.47%) reported using daily oral PrEP. Of these, 90 % adhered to a daily regimen, and 65 % had never missed a dose. The remaining 48 participants (25.53%) used event-driven PrEP; within the past three months, 79.17% adhered to the 2-1-1 dosing schedule. Regarding condom use while on PrEP, 39.89% of the total sample (n=188) reported consistent condom use. In terms of overall PrEP usage behavior, 141 participants (75.00%) demonstrated good adherence, while 47 (25 %) exhibited moderate adherence, and none were classified as having poor adherence.
CONCLUSIONS AND RECOMMENDATIONS: It is recommended to continue promoting knowledge, understanding, and access to PrEP services, as well as supporting correct and consistent medication behaviors. These efforts can help reduce HIV infection rates among high-risk populations and sustainably contribute to the goal of ending the AIDS epidemic at the provincial level.
