The Prevalence of Sexually Transmitted Infections and Sociosexual Behaviors in the South Korean Military Before and During the COVID-19 Pandemic

Abstract

Introduction: This study evaluated the epidemiological factors of sexually transmitted infections (STIs) among South Korean troops including the prevalence, therapeutic methods, and sexual risk behaviors.

Material and methods: The medical records of the STIs diagnosed troops at the Armed Forces Capital Hospital (AFCH) for 36 months (between January 2018 and December 2020) were retrospectively reviewed. The data collection for the study began after obtaining research approvals from the institutional ethics committee of AFCH. The patients were classified into two subgroups, pre-coronavirus disease 2019 (COVID-19) and COVID-19 groups. The clinical parameters of the patients including STI-related symptoms and underlying diseases were analyzed. The sociosexual conduct of the two study groups was evaluated and compared by using a survey questionnaire.

Results: Overall, 138 STI patients with mean age of 21.2 years were included (pre-COVID-19: 106 patients/COVID-19: 32 patients). 32.6% of the patients received college education before the military service. Regarding previous history of STIs, 24 patients (17.4%) had previous experience of STIs, which occurred before participation in the current study. Initial urine analysis results showed that 95 (68.8%) and 79 patients (57.2%) showed pyuria and bacteriuria, respectively. Neisseria gonorrhoeae (29.7%) was the most commonly identified pathogen. Each pathogen was treated with the therapies recommended by the current treatment guidelines, and no patient showed any recurrence of the disease during follow-up. Both pre-COVID-19 (91.5%) and COVID-19 (93.8%) groups showed high rates of binge drinking during off-duty. The pre-COVID-19 group had a greater number of patients (21.7%) having multiple sex partners (during the past 12 months) than the COVID-19 group (15.6%). The COVID-19 group had 18.8% of the troops involved in sexual activity even after the onset of STI-related clinical symptoms, whereas the rate was significantly higher than 2.8% of the pre-COVID-19 group (P = .001). The COVID-19 groups showed a significantly higher number of patients (four patients, 12.5%) experiencing suicidal ideation than the pre-COVID-19 group (two patients, 1.9%) (P = .010). Both groups showed <40% of condom use rates at the last sexual intercourse.

Conclusion: The soldiers with STIs showed high rates of binge alcohol consumption, while the rates of engaging in safe sex by using condoms are markedly low. Although the COVID-19 group was under influence of social distancing and military base lockdown, the soldiers' sociosexual conduct was not significantly different in the pre-COVID-19 group. The importance of education on alcohol misuse and safe sexual relationships should be taken more seriously within the military.
