Abstract
The increasing number of people living with human immunodeficiency virus (HIV) in Korea has prompted interest in using the national surveillance system as a database for studying their health. To investigate the relationships between socio-demographic and epidemiological characteristics and mortality rates, a nationwide retrospective cohort was formed by integrating surveillance data with the Cause of Death Statistics from Statistics Korea. This integration included incidence reports, epidemiological investigations, and death reports from the surveillance data, enriched with detailed mortality information from the Cause of Death data. The cohort comprised 17,199 adult Korean individuals diagnosed with HIV infection from 1985 to 2020. By the end of 2020, 2,721 of these individuals were confirmed deceased. The sex ratio of the study participants was 14.3:1.0 (male to female), with 78.2% being under 50 years old at the time of diagnosis. Sexual contact was identified as the primary transmission route, accounting for 75.7% of cases. HIV disease emerged as the predominant cause of death, representing two-thirds (1,817 of 2,721) of the fatalities, followed by injuries and trauma, malignancies, and cardiovascular diseases. Recommendations for further cohort studies may be submitted to the Korea Disease Control and Prevention Agency.

Summary
Korean summary
- 인체면역결핍바이러스 감염인들의 사망과 연관된 요인의 파악을 위해, 질병관리청의 국가 감시체계 데이터와 통계청 사망원인통계를 결합하여 후향적 코호트를 구성하였다.
- 구성된 코호트에는 1985-2020년 중 발생이 보고된 대한민국 국적의 19세 이상 감염인 17,199명이 포함되었으며 이 중 2,721명의 사망이 감시체계와 사망원인통계에서 최종 확인되었고, 코호트 데이터는 이들의 사회인구학적 요인, 역학적 요인, 사망원인을 포함한 사망 관련 정보로 구성되어 있다.
- 본 코호트에 기반한 연구를 통해 국내 거주하는 한국인 감염인들의 건강을 전반적으로 확인할 수 있을 것으로 생각되며, 감염인 중 사망 위험이 높은 취약군을 확인하는 등 국가 정책의 기반이 되는 과학적 근거를 생산할 수 있기를 기대한다.
Key Message
- By merging KDCA’s national surveillance data and the national mortality statistics, our retrospective cohort data have been established for identifying people living with HIV (PLHIV) at higher risk of mortality.
- In the established cohort, incidence reports of 17,199 PLHIV aged 19 or older with Korean nationality and mortality reports of 2,721 were included. The cohort data were composed of their sociodemographic and epidemiologic characteristics, and mortality data including causes of death.
- We expect further research based on the cohort to explore Korean PLHIV’s health and mortality risk, and to generate scientific evidence for national policymaking.
