Abstract：Objective To investigate the incidence trend of sexually transmitted diseases (STDs) in Yantian District, Shenzhen City, Guangdong Province from 2008 to 2022, and the effects of age, period, and cohort on STDs incidence, so as to provide the basis for formulating control measures for STDs. Methods Data of reported STDs cases (syphilis, gonorrhea, genital Chlamydia trachomatis infections, condyloma acuminatum and genital herpes) among population aged 15 to 64 years in Yantian District from 2008 to 2022 were collected through the Chinese Disease Control and Prevention Information System. The temporal and population distribution of STDs were descriptively analyzed. Trends in incidence of STDs were analyzed using average annual percent change (AAPC). Impacts of age, period and cohort on the incidence of STDs were analyzed by an age-period-cohort model. Results A total of 6 156 cases of STDs aged 15 to 64 years were reported from 2008 to 2022, and the average annual incidence was 229.92/105. The overall incidence showed an upward trend (AAPC=2.409%, P<0.05), and an upward trend among females (AAPC=5.846%, P<0.05), but the trend was not statistically significant among males (AAPC=0.193%, P>0.05). The incidence of STDs showed an increasing trend followed by a decreasing trend with the increase of age. The incidence trend among males was consistent with the overall population, reaching its peak in the age group of 30 to 34 years (371.04/105), while the incidence among females showed an increasing trend with the increase of age, peaking in the age group of 60 to 64 years (442.15/105). Compared with 2013-2017, the incidence risk of STDs showed an increasing trend in 2018-2022 (RR=1.349, 95%CI: 1.217-1.495). Compared with the birth cohort of 1975-1979, the incidence risk of STDs in 1980-2005 birth cohort showed an increasing trend, with the highest incidence risk in 2000-2004 birth cohort (RR=4.178, 95%CI: 2.717-6.423). Conclusions The overall incidence of STDs among residents aged 15 to 64 years in Yantian District from 2008 to 2022 appeared a tendency towards a rise. Age, period and cohort all had impacts on the incidence, with a greater effect among females than males.
