Abstract：Objective To investigate the epidemiological features and trends of syphilis among elderly population in Yibin City so as to provide a scientific basis for formulating prevention and control strategies of sexually transmitted diseases (STDs). Methods The data regarding the incidence of syphilis in people aged 60 years and above in Yibin City from 2007 to 2016 were collected to perform descriptive epidemiological analysis. Results A total of 1,102 syphilis cases in people aged 60 years and above in Yibin City during 2007-2016 were cumulatively reported, with the average annual incidence rate of 13.17/100,000. The incidence rates of syphilis during 2007-2016 showed an upward trend, with statistically significant differences (χ2tendency=275.23, P=0.000). The incidence rate in 2015 was the highest, reaching 25.35/100,000. The male-to-female ratio was 2.38:1, and there were statistically significant differences in the incidence rate between male and female (18.92/100,000 vs. 7.64/100,000,χ2=179.86, P=0.000). No statistically significant differences were found in the sex ratio among patients with different stages of syphilis (P>0.05) as well as among syphilis patients at different stages in different age groups (P>0.05). Most of the patients were latent syphilis(68.87%), followed by stage I syphilis(22.69%), stage Ⅱ syphilis(6.26%) and stage Ⅲ syphilis(2.18%). The number of syphilis patients at each stage showed a decreasing tendency with increasing age. Most of the patients were farmers (837/1,102, 75.95%), followed by homemakers and the unemployed (224/1,102, 20.33%). Conclusions The incidence rate of syphilis in elderly people aged 60 years and above in Yibin City during 2007-2016 showed an upward tendency. The incidence was higher in males than in females. The majority of the patients were latent syphilis, and most of them were farmers. Therefore, we should pay more attention to the detection of syphilis in the elderly, intensify the propaganda and intervention among the elderly, especially in farmers, and control the transmission and spread of syphilis.
