Main Article Content
Abstract
Background Currently, the situation of sexually transmitted infections (STIs) worldwide and in Thailand is increasing every year, especially among adolescents and youth. This correlates with the number of STI patients in Chiang Rai province, which ranks 5th in the country. Many patients still lack awareness of the dangers of these diseases. Therefore, this research aims to study the factors affecting the non-use of condoms among patients with STIs, to provide guidelines for promoting condom use to prevent sexually transmitted infections.
Objectives The study aims to investigate the prevalence and factors associated with having unprotected sex among individuals with sexually transmitted infections (STIs) in the Mueang Chiang Rai district.
Methods This is a cross-sectional study conducted on patients with sexually transmitted infections. Data were collected using a questionnaire to examine factors influencing the non-use of condoms during the most recent sexual encounter among individuals with sexually transmitted infections attending the Peer Health Clinic at Chiang Rai Prachanukroh Hospital from March 1 to August 31, 2024. A total of 100 participants were included in the study. The analysis was conducted using Multivariable logistic regression with the backward elimination method, and statistical significance was determined using a p-value of < 0.050.
Results A sample of 100 individuals had an average age of 23.94 (± 6.54) years. 60 individuals (60%) reported not using condoms during their most recent sexual encounter. When analyzing multiple factors simultaneously, the factor significantly associated with not using condoms was the lack of condoms during the most recent sexual encounter (aOR 171, 95% CI 36.15-808.90, p<0.001).
Conclusion and Recommendations The prevalence of not using condoms during the most recent sexual encounter among patients with sexually transmitted infections attending the Peer Health Clinic is 60%. The lack of condoms during sexual activity is a factor associated with not using condoms. Therefore, carrying condoms is a behavior that should be promoted and could lead to the development of future public health policies.
