HIV testing rates are suboptimal among at-risk men. Crowdsourcing may be a useful tool for designing innovative, community-based HIV testing strategies to increase HIV testing. The purpose of this study was to use a stepped wedge cluster randomized controlled trial (RCT) to evaluate the effect of a crowdsourced HIV intervention on HIV testing uptake among men who have sex with men (MSM) in eight Chinese cities.
An HIV testing intervention was developed through a national image contest, a regional strategy designathon, and local message contests. The final intervention included a multimedia HIV testing campaign, an online HIV testing service, and local testing promotion campaigns tailored for MSM. This intervention was evaluated using a closed cohort stepped wedge cluster RCT in eight Chinese cities (Guangzhou, Shenzhen, Zhuhai, and Jiangmen in Guangdong province; Jinan, Qingdao, Yantai, and Jining in Shandong province) from August 2016 to August 2017. MSM were recruited through Blued, a social networking mobile application for MSM, from July 29 to August 21 of 2016. The primary outcome was self-reported HIV testing in the past 3 months. Secondary outcomes included HIV self-testing, facility-based HIV testing, condom use, and syphilis testing. Generalized linear mixed models (GLMMs) were used to analyze primary and secondary outcomes. We enrolled a total of 1,381 MSM. Most were ≤30 years old (82%), unmarried (86%), and had a college degree or higher (65%). The proportion of individuals receiving an HIV test during the intervention periods within a city was 8.9% (95% confidence interval [CI] 2.2-15.5) greater than during the control periods. In addition, the intention-to-treat analysis showed a higher probability of receiving an HIV test during the intervention periods as compared to the control periods (estimated risk ratio [RR] = 1.43, 95% CI 1.19-1.73). The intervention also increased HIV self-testing (RR = 1.89, 95% CI 1.50-2.38). There was no effect on facility-based HIV testing (RR = 1.00, 95% CI 0.79-1.26), condom use (RR = 1.00, 95% CI 0.86-1.17), or syphilis testing (RR = 0.92, 95% CI 0.70-1.21). A total of 48.6% (593/1,219) of participants reported that they received HIV self-testing. Among men who received two HIV tests, 32 individuals seroconverted during the 1-year study period. Study limitations include the use of self-reported HIV testing data among a subset of men and non-completion of the final survey by 23% of participants. Our study population was a young online group in urban China and the relevance of our findings to other populations will require further investigation.
In this setting, crowdsourcing was effective for developing and strengthening community-based HIV testing services for MSM. Crowdsourced interventions may be an important tool for the scale-up of HIV testing services among MSM in low- and middle-income countries (LMIC).

Development of the non-occupational post-exposure prophylaxis (NPEP) knowledge scale among Chinese men who have sex with men
2023
Background
Nonoccupational post-exposure prophylaxis (NPEP) is a short course of medication taken to reduce the likelihood of acquiring human immunodeficiency virus (HIV) infection upon exposure. A review of the literature demonstrates an urgent need for an empirically validated instrument that measures detailed knowledge of NPEP among the key population of men who have sex with men (MSM).
Methods
Semi-structured interviews, focus groups, and a cross-sectional survey with a sample of 419 MSM was conducted in 2018 in China to develop and psychometrically evaluate the new instrument, the NPEP Knowledge Scale. Exploratory and confirmatory factor analyses, differential item functioning analyses, and structural equation modeling were conducted using Mplus 7.4.
Results
The NPEP Knowledge Scale demonstrated excellent reliability and validity. Cronbach’s alpha was 0.903. The range of item R
2
were 0.527–0.969,
p
’s < 0.001. Model estimated inter-item correlations ranged between 0.534 and 0.968. In addition, HIV knowledge, NPEP use, and NPEP knowledge were all significantly correlated.
Conclusions
The NPEP Knowledge Scale is suitable for research, program evaluation, and clinical and community services that require using NPEP to minimize the ever-present risk of new HIV infections.

HIV testing frequency and associated factors among five key populations in ten cities of China: a cross-sectional study
2022
Background
Regular HIV testing is the best way to detect people living with HIV promptly, yet not much is known about the characteristics of frequent, voluntary testers. This study explores factors related to HIV testing frequency among five key populations in China including men who have sex with men (MSM), female sex workers (FSWs), people who use drugs (PWUD), men who have casual sex with women (MCSW) and sero-negative partners among sero-discordant couples (SNPs).
Methods
We conducted a cross-sectional study in ten cities of China from November 2018 to September 2019 using convenience sampling to recruit participants. Univariate and multivariate partial proportional odds models were adopted to compare socio-behavioral factors associated with HIV testing frequencies among the five key populations.
Results
Among the 2022 recruited participants, 36.6% reported not testing for HIV in the past year, whereas 37.0% tested once and 26.4% tested twice. Compared with MSM, FSWs (AOR = 1.97, 95% CI: 1.36–2.86) and SNPs (AOR = 3.63, 95% CI: 2.40–5.49) were more likely to test for HIV, but MCSW (AOR = 0.23, 95% CI: 0.17–0.32) were less likely. Additionally, SNPs (AOR = 4.02, 95% CI: 2.78–5.83) were more likely to be frequent HIV testers, while FSWs (AOR = 0.49, 95% CI: 0.32–0.76) and MCSW (AOR = 0.29, 95% CI: 0.20–0.41) were less likely to be frequent testers. Factors identified as barriers to HIV testing include the following: higher education level and > 5000 CNY monthly income for FSWs; elder age and a married/cohabitating status for PWUD; reported alcohol use for MCSW; and non-Han ethnicity and non-local household for SNPs. Facilitators to frequent testing included the following: higher education level for MSM and SNPs; higher AIDS knowledge score for MSM and PWUD; > 5000 CNY monthly income for FSWs and PWUD; and reporting high-risk sexual behaviors for MSM, FSW and PWUD.
Conclusions
HIV testing frequencies and associated factors were not equivalent across the five key populations in China. Public health officials should take heed of the identified high-risk populations reporting high testing rates, perhaps with intensive and tailored behavioral interventions or biochemical prophylaxis.

Drug users’ awareness of and willingness to use HIV non-occupational post-exposure prophylaxis (nPEP) services in China: a mixed methods study
2022
Background
Drug users are regarded as a high-risk population for HIV infection. Non-occupational post-exposure prophylaxis (nPEP) is internationally regarded as an effective biomedical prevention against HIV but still a small-scale pilot project in China at present. The aim of this study was to understand drug users’ awareness of and willingness to use nPEP service in China.
Methods
This mixed methods study consisting of a qualitative study and a cross-sectional survey was conducted in two cities of China from 2018 to 2019. The in-depth interviews were audio-taped, transcribed verbatim and analyzed using thematic framework analysis. Univariate and multivariate logistic regressions were used to examine factors associated with drug users’ awareness of and willingness to use nPEP.
Results
There were 401 and 19 participants included in quantitative and qualitative study respectively. Among participants in quantitative study, 30.2% had heard of nPEP and 56.7% reported willingness to use nPEP in future HIV exposure. In multivariate analyses, nPEP awareness was associated with age, sex, education level, AIDS knowledge score and HIV risk perception. nPEP willingness was associated with AIDS knowledge score, HIV risk perception, alcohol use, monthly income and awareness of nPEP. The qualitative results showed the barriers to nPEP willingness included the fatigue after taking drugs, high cost and side effects of nPEP medication, long nPEP course, and fear of privacy disclosure.
Conclusion
Drug users had low nPEP awareness and only about half participants reported willingness to use nPEP. It is essential to promote nPEP education campaigns among drug users, especially for elders, women and those with lower education level. Simultaneously, price regulation, side effect management, psychological support and privacy protection need to be managed well when nPEP is routinized.

Unprotected anal intercourse (UAI) is a major pathway towards secondary HIV transmission among men who have sex with men (MSM). We explored the socio-cultural environment and individual beliefs and experiences conducive to UAI in the context of Southern China.
We employed an ethnographic approach utilizing a socio-ecological framework to conduct repeated in-depth interviews with thirty one newly diagnosed HIV positive MSM as well as participant observations in Shenzhen based healthcare settings, MSM venues and NGO offices.
Some men (6/31) reported continuing to practice UAI after an initial diagnosis of being HIV positive. For MSM who had existing lovers or stable partners, the fear of losing partners in a context of non-serostatus disclosure was testified to be a major concern. MSM with casual partners reported that anonymous sexual encounters and moral judgments played a significant role in their sexual risk behaviors. Simultaneously, self-reported negative emotional and psychological status, perception and idiosyncratic risk interpretation, as well as substance abuse informed the intrapersonal context for UAI.
UAI among these HIV positive MSM was embedded in an intrapersonal context, related to partner type, shaped by anonymous sexual encounters, psychological status, and moral judgments. It is important that prevention and intervention for secondary HIV transmission among newly diagnosed HIV positive MSM in China take into account these contextual factors.

Person-environment fit of formal and informal caregivers for older adults: a scoping review
2025
Background
Caring for older adults is a dynamic and complex process, and analyzing personal and environmental factors separately fails to capture its full nature. The person-environment fit theory offers a valuable framework to explore interactions between caregivers and their environments. This review aimed to synthesize evidence on the person-environment fit of formal and informal caregivers for older adults, identify gaps in existing literature, and propose future research directions.
Methods
The scoping review was conducted following the six-step guidance of the Joanna Briggs Institute 2020. A literature search was conducted in June 2024 across seven databases: Scopus, ProQuest, Web of Science, Embase, PubMed, MEDLINE, and CINAHL. Empirical studies published after 2000 regarding the person-environment fit of caregivers for older adults were included.
Results
A total of 15 eligible articles were included, with nine focusing on formal caregivers and six focusing on informal caregivers. Research on formal caregivers’ person-environment fit often came from human resource management perspectives and was supported by various theories. In contrast, studies on informal caregivers tended to draw from environmental gerontology theories and lacked a systematic analytical model. Most studies used self-designed questionnaires or interviews, with one employing a standard person-environment fit measurement scale. Caregivers’ person-environment fit was analyzed through “demands-abilities fit” and “needs-supplies fit” dimensions, covering various types like person-physical, person-interpersonal, value, goal, and caregiving-life fit. Findings indicated that a high level of person-environment fit was associated with better physical and mental well-being, stronger caregiving commitment, and improved care quality.
Conclusion
The holistic and dynamic nature of person-environment fit theory is closely aligned with the caregiving process, enhancing our understanding of the experiences of caregivers. Based on existing evidence, this review proposes a theoretical framework for analyzing informal caregivers’ person-environment fit. Further investigation into the theoretical framework of caregiver person-environment fit, along with the development of standardized assessment instruments, will significantly advance the well-being of both caregivers and care recipients.

Background
In China, non-occupational post-exposure prophylaxis (nPEP) is not a conventional service yet and nPEP related studies are very few. Recently, China’s 13th Five Year Action Plan for HIV/AIDS Containment and Prevention examines the feasibility of including nPEP as one of the national strategies for HIV prevention. However, there is a concern that nPEP use might exacerbate high-risk sexual activities. In order to facilitate a research-based policy making of routinizing nPEP services, the current study examined potential effects of nPEP use on condom use and number of sexual partners among Chinese men who have sex with men (MSM) .
Methods
A cross-sectional survey was conducted in two cities of China in November and December 2018. Descriptive analyses of participants’ sociodemographic and behavioral characteristics were conducted using SPSS 24.0. Mplus 7.4 was used to conduct confirmatory factor analysis and structural equation modeling.
Results
The sample included 419 Chinese MSM with a mean age of 28.04 (SD = 9.71). Participants reported more positive anticipation of their own behaviors than other MSM’s behaviors regarding condom use and number of sexual partners if nPEP were to be routinized in China. About 60% of participants reported discrepancies between anticipated individual and population behaviors as a potential result of routinization of nPEP services. Anticipated individual behavioral change was positively related to age and duration of residence in the current city, and negatively related to education. Anticipated population behavioral change was positively related to age. Anticipated behavioral discrepancy was positively related to being ethnic minority and never married.
Conclusions
These findings identify a high-risk subgroup of MSM, who reported they would use condoms less and/or have more sexual partners when nPEP becomes available. This subgroup of MSM might benefit from targeted health interventions. Moreover, there is a clear discrepancy between anticipated individual and population behavioral changes regarding future routinization of nPEP services, suggesting incorporating nPEP services as a means of community development for MSM.

This paper reports on an ethnographic study of male homosexuality in contemporary Chinese society. The study focused on how men negotiated with the mainstream Chinese heterosexual society and in so doing constructed their sexual identities. The factors found to inform sexual identity were: the cultural imperative of heterosexual marriage, normative family obligations, desired gender roles, emotional experiences and a need for social belonging. The four types of sexual identities constructed included: establishing a deliberate non-homosexual identity, accumulating an individual homosexual identity, forming a collective homosexual identity and adopting a flexible sexual identity. For the men interviewed, sexual identity was both fluid and fragmented, derived from highly personalised negotiations between individualised needs and social and cultural constructs. The analysis is set against the background of China's rapid and recent economic development, shifting national and international social environments and improved access to the Internet.

Condom use peer norms and self-efficacy as mediators between community engagement and condom use among Chinese men who have sex with men
2017
Background
Community engagement strategies are often integrated in public health interventions designed to promote condom use among men who have sex with men (MSM), a key population for HIV prevention. However, the ways in which condom use peer norms and self-efficacy play a role in the association between community engagement and condom use is unclear. This study examines the potential mediating roles of peer norms and self-efficacy in this association.
Methods
A nationwide cross-sectional online survey was conducted among Chinese MSM in 2015. Recruitment criteria included being born biologically male, being older than 16 years, having had anal sex with a man at least once during their lifetime, and having had condomless anal or vaginal sex in the past three months. Mplus 6.11 was used to conduct confirmatory factor analysis and path modeling analysis to examine the structural relationships between HIV/sexual health community engagement (e.g., joining social media and community events related to HIV and sexual health services), condom use peer norms, condom use self-efficacy, and frequency of condom use.
Results
The study found that HIV/sexual health community engagement, condom use peer norms, condom use self-efficacy, and frequency of condom use were mutually correlated. A good data model was achieved with fit index: CFI = 0.988, TLI = 0.987, RMSEA = 0.032, 90% CI (0.028, 0.036). HIV/sexual health community engagement was associated with frequency of condom use, which was directly mediated by condom use peer norms and indirectly through self-efficacy.
Conclusion
The study suggests that condom use peer norms and self-efficacy may be mediators in the pathway between community engagement and condom use, and suggests the importance of peer-based interventions to improve condom use.

Introduction Qualitative research on antiretroviral therapy (ART) adherence interventions can provide a deeper understanding of intervention facilitators and barriers. This systematic review aims to synthesize qualitative evidence of interventions for improving ART adherence and to inform patient‐centred policymaking. Methods We searched 19 databases to identify studies presenting primary qualitative data on the experiences, attitudes and acceptability of interventions to improve ART adherence among PLHIV and treatment providers. We used thematic synthesis to synthesize qualitative evidence and the CERQual (Confidence in the Evidence from Reviews of Qualitative Research) approach to assess the confidence of review findings. Results Of 2982 references identified, a total of 31 studies from 17 countries were included. Twelve studies were conducted in high‐income countries, 13 in middle‐income countries and six in low‐income countries. Study populations focused on adults living with HIV (21 studies, n=1025), children living with HIV (two studies, n=46), adolescents living with HIV (four studies, n=70) and pregnant women living with HIV (one study, n=79). Twenty‐three studies examined PLHIV perspectives and 13 studies examined healthcare provider perspectives. We identified six themes related to types of interventions, including task shifting, education, mobile phone text messaging, directly observed therapy, medical professional outreach and complex interventions. We also identified five cross‐cutting themes, including strengthening social relationships, ensuring confidentiality, empowerment of PLHIV, compensation and integrating religious beliefs into interventions. Our qualitative evidence suggests that strengthening PLHIV social relationships, PLHIV empowerment and developing culturally appropriate interventions may facilitate adherence interventions. Our study indicates that potential barriers are inadequate training and compensation for lay health workers and inadvertent disclosure of serostatus by participating in the intervention. Conclusions Our study evaluated adherence interventions based on qualitative data from PLHIV and health providers. The study underlines the importance of incorporating social and cultural factors into the design and implementation of interventions. Further qualitative research is needed to evaluate ART adherence interventions.
