A longitudinal study of persistent smoking among HIV-positive gay and bisexual men in primary relationships

Factors Influencing Tobacco Smoking and Cessation Among People Living with HIV: A Systematic Review and Meta-analysis

Tobacco smoking is highly prevalent among people living with HIV (PLWH), yet there is a lack of data on smoking behaviours and effective treatments in this population. Understanding factors influencing tobacco smoking and cessation is crucial to guide the design of effective interventions. This systematic review and meta-analysis of studies conducted in both high-income (HICs) and low- and middle-income countries (LMICs) synthesised existing evidence on associated factors of smoking and cessation behaviour among PLWH. Male gender, substance use, and loneliness were positively associated with current smoking and negatively associated with smoking abstinence. The association of depression with current smoking and lower abstinence rates were observed only in HICs. The review did not identify randomised controlled trials conducted in LMICs. Findings indicate the need to integrate smoking cessation interventions with mental health and substance use services, provide greater social support, and address other comorbid conditions as part of a comprehensive approach to treating tobacco use in this population. Consistent support from health providers trained to provide advice and treatment options is also an important component of treatment for PLWH engaged in care, especially in LMICs.

Peer navigation for smoking cessation in smokers with HIV: Protocol for a randomized clinical trial

BACKGROUND

Smoking prevalence in persons with HIV (PWH) is high (40%) and cessation rates remain low. Lack of social support and poor adherence to nicotine replacement therapy (NRT) are related to poor cessation outcomes; thus, both factors represent possible targets for smoking cessation interventions. Peer navigators (PNs) have been integrated into HIV care with great success to improve engagement and adherence to antiretroviral therapy. However, no clinical trial has evaluated the potential for PNs to provide social support and improve NRT adherence for smoking cessation. We developed a treatment protocol that targets social support, adherence, and self-efficacy for quitting by incorporating PNs into a smoking cessation program. This randomized trial will test whether this approach results in higher rates of 7-day point prevalence abstinence at 12- and 24-weeks, compared to standard treatment.

METHODS

Seventy-two smokers with HIV will be randomized to either Peer Navigation Social Support for smoking cessation (PNSS-S) or standard cessation counseling. All participants will meet with a nurse for a smoking cessation counseling session, which will include discussion of FDA-approved cessation pharmacotherapy. Participants assigned to PNSS-S will receive weekly phone calls from the PN for 12 weeks. The PN will address readiness to quit, using medication to quit, common barriers to cessation, high risk situations, slip management, and maintaining abstinence. Smoking cessation outcomes will be measured at 4, 12, and 24 weeks following the baseline appointment.

CONCLUSION

Results from this study will provide preliminary evidence of whether incorporating a peer navigator-based intervention into smoking cessation treatment can improve smoking cessation outcomes in PWH.

Couples-based approach to HIV prevention for transgender women and their partners: study protocol for a randomised controlled trial testing the efficacy of the 'It Takes Two' intervention

INTRODUCTION

HIV transmission and acquisition risk among transgender women is particularly high in the context of primary partnerships. This project extends a previous pilot couples-focused HIV intervention programme, which was shown to be feasible, acceptable and promising in reducing sexual risk behaviour among transgender women and their partners. This randomised controlled trial (RCT) tests the efficacy of this culturally sensitive HIV prevention programme for HIV-serodiscordant and HIV-negative seroconcordant transgender women and their partners.

METHODS AND ANALYSIS

To finalise the protocol for trial, we used qualitative methods to hone eligibility criteria, refine the intervention and control manuals, and name and brand the intervention ('It Takes Two'). The RCT investigates the effects of the It Takes Two intervention on Composite Risk for HIV (CR-HIV) among 100 couples. CR-HIV is a binary indicator of couple HIV risk using validated measures of sexual behaviour, pre-exposure prophylaxis use among HIV-negative participants and viral suppression among participants living with HIV. Using a two-arm RCT, we will examine intervention effects on CR-HIV at 12-month follow-up comparing transgender women and their partners randomised to the intervention versus control (HIV prevention information only).

ETHICS AND DISSEMINATION

This study has been reviewed and approved by the University of California, San Francisco (19-28624) and the University of Michigan (HUM00147690) Institutional Review Boards. Participants provide informed consent before taking part of the study activities. Results will be published in peer-reviewed journals and presented at scientific conferences. We will make our results available to the community of researchers and general public interested in transgender health to avoid unintentional duplication of research, as well as to others in the health and social services community, including LGBT community-based organisations, AIDS service organisations and other transgender-serving organisations. The full de-identified dataset and codebook will be shared at the University of Michigan Digital Repository.

Comparisons Between Smoking Patterns Among Sexual Minority Females and Males in Romantic Relationships

PURPOSE

Several studies have noted sexual minority disparities in tobacco smoking; however, few studies have examined the role of intimate partners in these different smoking behaviors among sexual minority men and women. Furthermore, few studies distinguish between intermittent and daily smokers. Thus, this study sought to examine whether perceptions of their partner's smoking behaviors were associated with their own smoking behaviors in a sample of sexual minority adults in romantic relationships.

METHOD

In total, 898 participants (413 sexual minority females and 485 sexual minority males) completed a one-time online anonymous survey.

RESULTS

Approximately one third of the sample reported smoking, with 21.2% daily smokers and 9.8% intermittent smokers. Multinomial regression results revealed that for both sexual minority females and males having a partner who was a daily or intermittent smoker was associated with an increased odds of being a daily smoker, whereas having a partner who was an intermittent smoker was associated with an increased odds of being an intermittent smoker.

CONCLUSIONS

These findings provide valuable information on the need to attend to romantic partners and consider tailored programming to account for different smoking patterns and partners' potential role in reinforcing smoking.

Perceived barriers to smoking cessation and perceptions of electronic cigarettes among persons living with HIV

Smoking is more prevalent in persons living with HIV than the general population and is linked to increased morbidity and mortality. Some have suggested that based on current knowledge of harms and benefits, it may be feasible to advise smokers who are unable or unwilling to quit to switch to electronic cigarettes (ECs) as a less harmful alternative. We conducted 25 qualitative interviews with HIV-positive current or former smokers to explore perceived barriers to smoking cessation and perceptions of ECs. A high level of nicotine dependence, smoking as a form of stress management, motivational factors (including lack of readiness, low self-efficacy, ambivalence toward quitting), and having a social network of smokers were identified as cessation barriers. Low knowledge of ECs and uncertainty about EC safety and efficacy were barriers to EC uptake. However, current smokers indicated a willingness to try ECs. This study provides evidence that HIV-positive smokers face significant individual and environmental barriers to cessation. ECs may have potential as a harm reduction strategy in this population; however, there is a significant need for education regarding use and relative safety.

Assessing the longitudinal stability of latent classes of substance use among gay, bisexual, and other men who have sex with men

BACKGROUND

Association between substance use and HIV-risk among gay and bisexual men (GBM) is well documented. However, their substance use patterns are diverse, and it is unknown whether self-reported use patterns are stable over time.

METHODS

Sexually-active GBM, aged >16 years, were recruited in Metro Vancouver using respondent-driven sampling and followed across 5 study visits at six-month intervals (n = 449). To identify distinct patterns of substance use and their longitudinal stability, Latent Transition Analysis (LTA) was conducted for drugs reported by at least 30 participants. Intraclass correlation coefficients (ICC) quantified the stability of class assignments.

RESULTS

Six classes characterizing 'limited drug use' (i.e., low use of all drugs, except alcohol), 'conventional drug use' (i.e., use of alcohol, marijuana, and tobacco), 'club drug use' (i.e., use of alcohol, cocaine, and psychedelics), 'sex drug use' (i.e., use of alcohol, crystal meth, GHB, poppers, and erectile dysfunction drugs), 'street drug use' (i.e., use of alcohol and street opioids) and 'assorted drug use' (i.e., use of most drugs) were identified. Across five visits (2.5 years), 26.3% (n = 118/449) of GBM transitioned between classes. The prevalence of limited use trended upwards (Baseline:24.5%, Visit 5:28.3%, p < 0.0001) and assorted use trended downwards (13.4%-9.6%, p = 0.001). All classes had strong longitudinal stability (ICC > 0.97).

CONCLUSION

The stability of latent substance use patterns highlight the utility of these measures in identifying patterns of substance use among people who use drugs - potentially allowing for better assessment of these groups and interventions related to their health.

Tobacco Use and Sustained Viral Suppression in Youth Living with HIV

Tobacco has been associated with worse HIV disease progression in adult samples of people living with HIV; however, studies have yet to examine these effects in youth living with HIV (YLWH). This study examined the association between tobacco smoking behaviors and sustained viral suppression among a sample of 820 YLWH who were recruited through the Adolescent Medicine Trials Network for HIV Interventions. Participants completed a cross-sectional survey and then staff abstracted viral suppression data from medical records for up to 26 weeks prior to enrollment. Overall, 20.4% of youth reported daily or almost daily tobacco use. In multivariable analyses, older age and daily or almost daily tobacco smoking, and ART adherence remained statistically significant in predicting sustained viral suppression over the study period. These findings underscore the need for tobacco screening and interventions in HIV care settings in order to identify youth in need of additional smoking cessation services.
