Summary What is already known about this topic?Given the common modes of transmission,outbreaks of both human immunodeficiency virus(HIV)and syphilis are primarily observed in men who have sex with men(MSM).However,minimal research has been conducted to concurrently evaluate the rates and trends of HIV and syphilis incidence within this community in China.What is added by this report?

Correlates of Sexual Lifestyles Among Older Adults Living With HIV in China: Findings From the Sexual Well-being (SWELL) Study

Sexual lifestyles are closely related to overall human health and well-being.Few studies have focused on sexual lifestyles among older adults living with HIV(OALHIV),especially in low-and middle-income countries.This study is a part of the sexual well-being among older adults in China(SWELL)study,which is a multicenter cross-sectional study focused on sexual health among older adults aged 50 years and older.Participants were 680 OALHIV(≥50 years old)from the SWELL study conducted from June 2020 to December 2022.Data were collected through one-on-one interviews.We used logistic regression to assess the correlates of sexual activity and sexual satis-faction.Among all participants,37.1%were sexually active.Being older,male,in a steady relationship and employed were associated with being sexually active.The prevalence of sexual satisfaction was 69.8%among sexually active OALHIV.Being homosexual and reporting a better general health status were associated with sexual satisfaction.The OALHIV who have depressive symptoms were less likely to report sexual satisfaction.To support holistic healthy aging among OALHIV,it is important for healthcare providers to be educated about the importance of enquiring about sexual activity,satisfaction and problems and addressing concerns while conveying sex-positive attitudes during clinical reviews,as these are still critical aspects of their health and well-being.

Economic Evaluation of the Comprehensive AIDS Prevention and Control Program—Tianjin Municipality,China,2011-2022

What is already known about this topic?Acquired immunodeficiency syndrome(AIDS)represents a significant public health challenge globally,not only inflicting harm on the health of individuals but also placing a considerable economic strain on society.What is added by this report?This study represents the inaugural report on the potential reduction in economic burden attributable to human immunodeficiency virus(HIV)prevention strategies in Tianjin.Between 2011 and 2022,it is estimated that effective measures could prevent 2,965 new HIV infections and avert 658 deaths,resulting in an economic benefit of approximately 14.437 billion Chinese Yuan.What are the implications for public health practice?The findings of this study offer valuable evidence to inform the development of localized HIV prevention and control strategies,as well as to guide public health policymaking.

HIV-Related Knowledge, Attitude, and Practices Research Among College Students-Six Chinese Cities, 2021

Summary What is already known about this topic?The number of newly diagnosed human immunodeficiency virus(HIV)cases among Chinese youth 15–24 years of age shows an upward trend between 2010 and 2019.What is added by this report?This survey is on a larger scale as compared to previous studies.It shows inadequate HIV knowledge—especially on HIV treatment,self-testing,and postexposure prophylaxis—among college students.A significant gap exists between knowledge and behavior as indicated by the low condom use rate despite a high knowledge level.

HIV incidenee and risk factors among transgender women and cisgender men who have sex with men in two cities of China:a prospective cohort study

Background:HIV epidemic among men who have sex with men(MSM)remains a major public health concern in China.Despite a growing body of research on transgender women worldwide,little is known about Chinese transgender women within MSM.We sought to estimate HIV incidence and distinguish risk factors of HIV acquisition among them from that among cisgener(non-transgender)MSM(cis-MSM).Methods:We conducted an open cohort study among Chinese MSM,including those who were identifed as transgender in Shanghai and Tianjin.Participants were initially recruited by local community-based organizations from January to June,2016,and were followed up approximately every 6 months until June 2018.At each visit,a structured questionnaire was used to gather information on demographics,sexual risk behaviors,and HIV status.HIV incidence was calculated as the number of seroconversions divided by total number of person-years of follow-up among HIV-negatives at baseline.Risk factors of HIV acquisition were assessed by univariate and multivariate Cox regression models with time-dependent variables.Results:A total of 1056 participants contributed 1260.53 person-years(PYs)of follow-up,33 HIV seroconversions occurred during the follow-up period,yielding an estimated HIV incidence of 2.62(95%CI 1.80–3.68)per 100 PYs.HIV incidence among transgender women was 4.42 per 100 PYs,which was signifcantly higher than that of 1.35 per 100 PYs among cis-MSM,demonstrating a threefold higher odds of HIV infection than cis-MSM.For transgender women,those lived locally≤2 years(adjusted hazard ratio[aHR]=1.76,95%CI 1.13–2.76)and unprotected anal sex last time(aHR=4.22,95%CI 1.82–9.79)were more likely to acquire HIV.For cis-MSM,factors associated with HIV acquisition were frequency of anal sex≥3 times in past one month(aHR=4.19,95%CI 1.06–16.47)and unprotected anal sex last time(aHR=5.33,95%CI 1.52–18.73).Conclusions:Compared to cis-MSM,transgender women were at higher risk of HIV acquisition,highlighting an urgent need of tailored prevention.Future HIV program should consider to include them to ensure that this population in China are not left behind.
