A Randomized Controlled Trial Evaluating Efficacy of Promoting a Home-Based HIV Self-Testing with Online Counseling on Increasing HIV Testing Among Men Who Have Sex with Men.

We developed an innovative home-based HIV self-testing (HIVST) service that included mailing of a free HIVST kit, and providing online real-time instructions and pre-test/post-test counseling (HIVST-OIC). The present parallel-group and non-blinded randomized controlled trial was conducted to evaluate the efficacy of promoting HIVST-OIC in increasing HIV testing rate among 430 men who have sex with men (MSM), with access to online live-chat applications in Hong Kong. At month 6, as compared to the control group, the intervention group reported significantly higher prevalence of HIV testing of any type (89.8 vs. 50.7%; relative risk (RR): 1.77; p < 0.001). Among those who have taken up any HIV testing in the last six months, significant between-group difference was found in multiple male sex partnerships (34.2 vs. 47.7%, RR: 0.72; p = 0.021). HIVST-OIC has a strong potential in increasing prevalence of HIV testing and reducing sexual risk behaviors. Implementation research is warranted.

Behavioral intention to take up different types of HIV testing among men who have sex with men who were never-testers in Hong Kong.

Human immunodeficiency virus (HIV) testing is an important global prevention strategy but underutilized by local men who have sex with men (MSM). This study investigated the prevalence of behavioral intention to take up HIV testing (specific or any type), in the next six months among MSM who had not been tested for HIV in the last three years (never-testers) in Hong Kong. The data was based on 141 never-testers of 430 MSM who completed the anonymous baseline telephone survey of an ongoing randomized controlled trial from January 2015 to August 2015. Only 17.7% of them showed strong intention to take up any type of HIV testing in the next six months. Adjusted analysis showed that perceived benefit of HIV testing (adjusted odds ratio [AOR]: 1.29, 95% confidence interval [CI]: 1.01, 1.66), perceived psychological barriers of HIV testing (AOR: 0.85, 95%CI: 0.73, 1.00), and perceived self-efficacy in taking up HIV testing (AOR: 1.28, 95%CI: 1.07, 1.52) were significantly associated with behavioral intention to take up any HIV testing. Perceived cue to action from non-governmental organization staff was positively associated with a marginal p-value of 0.077 (AOR: 2.37, 95%CI: 0.97, 5.77). It is warranted to strengthen perceived benefit, remove psychological barriers, and increase perceived self-efficacy related to HIV testing. Innovative and effective health promotions are greatly needed to increase HIV testing coverage among never-testers.

Development of a Community-Based Network to Promote Anti-Drug Messaging and Identify Hidden Drug Abusers in Hong Kong.

Developing a community-based network by training peers as anti-drug ambassadors (ADAs) is a feasible strategy to identify hidden drug abusers. The Ask, Warn, Advise, Refer and Do-it-again (AWARD) model of smoking cessation is useful for enhancing people's confidence in making referrals to anti-drug services. This study evaluated the effectiveness of such a network by examining the change in knowledge, attitudes and practices (KAP) of 198 ADAs aged 13-18 before and after six months of our training. A one-group pre-test and repeated post-test design was used. One-way repeated-measures analysis of variance was applied to assess the changes in KAP, with p-values adjusted by Bonferroni correction. The results showed that the ADAs statistically significantly improved their KAP regarding drug abuse at the six-month follow-up compared to baseline. All ADAs who knew drug abusers (n = 3) had referred them to services based on the AWARD model. A total of 154 anti-drug abuse activities were conducted, reaching 4561 people. Based on the results, we concluded that the community-based network was effective in improving the KAP of ADAs regarding drug abuse, as well as referring hidden drug abusers. Future studies should consider implementing the network on a larger scale, thus maximizing its anti-drug capacity.

Prevalence of psychological problems and relationships with condom use and HIV prevention behaviors among Chinese female sex workers in Hong Kong.

The present study investigated the prevalence of psychological problems and their relationships with relevant HIV prevention behaviors among female sex workers (FSWs). An anonymous cross-sectional survey was conducted. With a mapping exercise, 293 Chinese FSWs were recruited from a red-light district in Hong Kong. Results showed high prevalence of psychological problems among FSWs: substance use (40.4%), probable depression (53.9%), self-harm tendencies (34-38%), poor self-esteem (48-52%), and pessimistic future outlook (46-47%). Inconsistent condom use was common (51% with clients, 23% with one-night-stand sex partner, and 73% with boyfriends). Over 70% had not used HIV-related prevention services in the last 6 months. Multivariate analyses indicated that psychological problems were significantly associated with inconsistent condom use and non-use of prevention services. The poor psychological well-beings of FSWs have important public health implications. Relevant professional services should be provided and integrated with HIV prevention efforts.

Variations in condom use by locale: a comparison of mobile Chinese female sex workers in Hong Kong and mainland China.

The present study investigated the prevalence of HIV and HIV-related behaviors and perceptions among 336 female sex workers (FSW) traveling from mainland China to work in Hong Kong. None of the participants tested HIV positive. Of the participants, 13.2% and 26.8%, respectively, would have unprotected sex with a client in Hong Kong or in mainland China if they liked the client; 16.7% and 21.7%, respectively, would have unprotected sex with a client in Hong Kong and in mainland China if he paid more. Of the participants, 98.5% used condoms in the last episode of sex work in Hong Kong and 78.1% were consistent condom users in Hong Kong in the last month. Yet, among those who previously worked as FSW in mainland China (n = 141), only 28.6% used condoms consistently in mainland China in the last year; 60% of those who used condoms inconsistently while in mainland China became consistent condom users in Hong Kong. Among those who did not use condoms in mainland China, willingness to have unprotected sex with a client who was liked by the FSW was a strong predictor for consistent condom use in Hong Kong (OR = 18.67, p < .001). Among those who were consistent condom users in Hong Kong, the same variable predicted inconsistent condom use while in mainland China (OR = 14.02, p < .05). Condom use behaviors change when FSW are working in different social contexts and behavioral changes are possible. Education programs should take socio-contextual factors into account.

Prevalence of induced abortion and associated factors among Chinese female sex workers in Hong Kong.

In this study, we interviewed 293 Chinese female sex workers (FSW) in Hong Kong of them, 55.6% of had experienced induced abortion 52.0% of which were accomplished in registered clinics. Those who were older, married, with frequent insomnia, did not use condom in the last episode of serving a client, and would agree not to use condom if paid more, were more likely than others to have had induced abortion (multivariate OR = 2.34 to 3.64). Those who were younger, had harmed herself, and drank at least 5 cans of beer per day (OR = 0.36 to 3.02) were more likely than others to have the induced abortion performed via improper means.

Prevalence of HIV and factors associated with risk behaviours among Chinese female sex workers in Hong Kong.

The study examined the HIV prevalence and factors associated with risk behaviours among Chinese female sex workers (FSW) in Hong Kong. Unlinked anonymous HIV antibody testing and interviews, using structured questionnaires, were conducted for 293 FSW. None was tested HIV positive. In the last 6 months, 13.7% self-reported having contracted STD, 50.7% were not using condoms with their male clients consistently; 73.3% and 22.6% respectively had had unprotected sex with boyfriends and one-night-stand partners. Believing that condom use with a boyfriend is a mistrust and the perception that one did not have full control over condom use decisions, would agree not to use condoms if being paid more, and could not refuse to have unprotected sex with clients were significantly associated with condom use with various types of sex partners (OR =1.95 to 4.83). FSW has low HIV prevalence but high prevalence of risk behaviours. Bridging effects exist. Empowerment of FSW is warranted.
