  • Epidemiological trends of five sexually transmitted infections in China

    ObjectiveTo analyze the epidemiological burden and change trend of five sexually transmitted infections (STIs) in China from 1990 to 2019. MethodsThe estimated numbers and standardized rates of STIs incidence, prevalence, and disability-adjusted life years (DALY) in China and other regions were obtained from the Global Burden of Disease Study 2019. The epidemic burden and change trend of STIs in China were compared and evaluated. ResultsIn 2019, STIs affected about 242 million people in China, resulting in 173 million new cases and 350 000 person years of DALY losses. Compared with 1990, the prevalence and incidence of STIs increased by 59.75% and 30.02%, respectively, and the number of DALY decreased by 35.19%. From 1990 to 2019, the incidence rate of chlamydia infection and gonococcal infection in the young and middle-aged group (aged 15-49 years) showed an upward trend; in addition, the DALY rate of genital herpes and trichomoniasis also increased. Among the 5 STIs, the disease burden caused by trichomoniasis infection in women was much higher than that in men. With the increase in the socio-demographic index (SDI), the burden of STIs in China gradually decreased. After the SDI exceeded 0.65, the decline rate of standardized DALY rate sharply increased. ConclusionThe disease burden of STIs in China shows a downward trend from 1990 to 2019, and the disease burden of the young and middle-aged group (aged 15-49 years) is the most significant, especially in trichomoniasis and chlamydia infection.
