Nested case-control study investigating factors affecting initial adoption of HIV self-testing among men who have sex with men in Guangzhou, China
Background: China has been exploring HIV self-testing (HIVST) among men who have sex with men (MSM) since 2014. Currently, both non-profit and commercial initiatives HIVST services have achieved comprehensive coverage. Investigating the factors influencing the initial adoption of HIVST among MSM in this context can help develop tailored HIVST service strategies of and further promote HIVST adoption among MSM communities. Methods: We selected 230 …
Psychosocial correlates of free Mpox vaccination intention among men who have sex with men in China
Background: The outbreak of Mpox in China has rendered the promotion of effective preventive measures among susceptible populations particularly crucial. We aimed to explore the correlates and develop a model for Mpox vaccination intention. Methods: We distributed a questionnaire to a sample of 2403 men who have sex with men to investigate whether they would get a Mpox vaccine. The participants were randomly split into a training set and a testin…
Cost-effectiveness of low-dose CT screening for non-smokers with a first-degree relative history of lung cancer

Do gay and bisexual men who conceal their same-sex behavior prefer different kinds of health services? Findings across four cities to inform client-centered HIV prevention in China
Our hypothesis that MSM who had disclosed versus never disclosed same-sex behavior would differ in the value they placed on different dimensions of sexual health service was partially borne out. As health authorities in China decide on implementation models for pre-exposure prophylaxis (PrEP) delivery and specifically within which institutions to integrate PrEP services, the preferences of target populations should be considered to develop compre…
Effectiveness of a Psycho-Social Intervention Aimed at Reducing Attrition at Methadone Maintenance Treatment Clinics
Methadone maintenance treatment (MMT) is an important approach to address opioid dependence. However, MMT clinics usually report high attrition rates. Our previous randomized controlled trial demonstrated additional psycho-social services delivered by social workers could reduce attrition rates compared to MMT alone. This study aimed to evaluate the effectiveness of psycho-social service in a real-world context. A quasi-experimental design and pr…
The characteristics of mixing patterns of sexual dyads and factors correlated with condomless anal intercourse among men who have sex with men in Guangzhou, China
Our study indicates that the strength of sexual dyadic relational ties and different social communication mixing patterns across ages, educational categories, and marital status were associated with CAI
Psychosocial Correlates of HIV Testing Frequency Among Men Who Have Sex with Men in Guangzhou, China
Can HIV service data be used for surveillance purposes
HIV service data can complement existing HIV surveillance systems for MSM in China, though it may underestimate the HIV prevalence (HSS+ data contains people whose status is already know, while service data contains people who were initially negative or people of unknown status). HIV service data can be used for surveillance purposes, when prerequisite variables are collected from a large number people, if the quality assessment is conducted
Resilience associated with mental health problems among methadone maintenance treatment patients in Guangzhou, China
A considerable proportion of methadone maintenance treatment (MMT) clients have experienced mental health problems (e.g., depression and anxiety), and poor mental health status is associated with HIV-related risk behaviors and treatment drop-out. Resilience is known to be a protective factor for mental health problems but is not studied among MMT clients in China. This study aimed to explore the relationship between resilience and mental health p…
Club drugs and alcohol abuse predicted dropout and poor adherence among methadone maintenance treatment patients in Guangzhou, China
Club drugs and alcohol abuse are prevalent among methadone maintenance treatment (MMT) patients. However, little is known about the association between these abuse and treatment outcomes among MMT patients. The aim of this study was to examine the prevalence of club drugs and alcohol abuse among MMT patients and to investigate the associations between these abuse and treatment outcomes - dropout and poor adherence.

HIV Linkage to Care and Retention in Care Rate Among MSM in Guangzhou, China
Depression, suicidal ideation, and related factors of methadone maintenance treatment users in Guangzhou, China
Mental health problems are prevalent among drug users. Methadone maintenance treatment (MMT) is an evidence-based effective treatment for drug addiction; however, there are few studies investigating depression, suicidal ideation, and their related factors among MMT users. In this cross-sectional study, 648 MMT users were recruited from six MMT clinics in Guangzhou, China. Data were collected through face-to-face interviews by trained interviewers…

摘要
Situation-specific factors predicting nonadherence to methadone maintenance treatment
Methadone maintenance treatment (MMT) is a key risk reduction measure for controlling HIV transmission among drug users. Studies using traditional methods exist to distinguish between drop outs and nondrop outs. However, many nondrop outs use MMT discontinuously and no study has identified situation-specific factors predicting their showing or not showing up. This study used a case-crossover design comparing situation-specific factors appearing o…
