Prevalence and correlates of smoking and e-cigarette use among young men who have sex with men and transgender women

Harm perceptions of vaping nicotine relative to cigarette smoking among sexual and gender minority young adults

INTRODUCTION

To address gaps in existing research, the current study used a mixed-methods approach to describe, contextualise and understand harm perceptions of vaping nicotine relative to cigarette smoking and associations with nicotine and tobacco (NT) use among young adults who identify their genders and sexualities in ways that classify them as sexual and gender minorities (SGM).

METHODS

Results are based on cross-sectional surveys and online qualitative interviews with 98 SGM young adults (18-25 years old) in California's San Francisco Bay Area who currently or formerly used combustible tobacco. We generated a measure assessing participants' relative harm perceptions of e-cigarette use versus cigarette smoking and identified those who perceived cigarette smoking as more harmful than e-cigarette use compared to those who perceived it to be equally or less harmful.

RESULTS

We found that relative harm perceptions of cigarette smoking versus e-cigarette use are likely related to much uncertainty and confusion about the harms of e-cigarette use. Moreover, findings illustrate that public health messages regarding the risks of e-cigarette use may have unintended consequences of increasing cigarette use to replace e-cigarette use for some SGM young adults, a practice that is incongruent with scientific evidence demonstrating that cigarettes and other combustible tobacco products are riskier than e-cigarettes and other forms of NT use.

DISCUSSION AND CONCLUSIONS

Results suggest the need for evidence-based, clear, and direct messaging about the relative harms of cigarettes versus e-cigarettes to reduce NT-related inequities in SGM populations.

Stressors Associated with Tobacco Use Among Trans Women

Purpose

Tobacco use is prevalent among sexual and gender minorities (SGM), yet few studies have examined the specific drivers of tobacco use among trans women. The purpose of this study is to examine the impact of proximal, distal, and structural stressors associated with tobacco use among trans women.

Methods

This study is based on a cross-sectional sample of trans women (n=162) living in Chicago and Atlanta. Analyses were conducted to examine the association between stressors, protective factors, and tobacco use using a structural equation modeling framework. Proximal stressors (transgender roles scale, transgender congruence scale, internalized stigma, and internalized moral acceptability) were operationalized as a higher order latent factor, while distal stressors were operationalized as observed variables (discrimination, intimate partner violence, sex work, rape, child sexual abuse, HIV, and violence). Protective factors included social support, trans-related family support, and trans-related peer support. All analyses adjusted for sociodemographic variables (age, race/ethnicity, education, homelessness and health insurance).

Results

The prevalence of smoking among trans women in this study was 42.9%. In the final model, homelessness (odds ratio [OR]: 3.78; 95% confidence interval [CI]: 1.97, 7.25), intimate partner violence (OR: 2.14; 95% CI: 1.07, 4.28), and commercial sex work (OR: 2.22; 95% CI: 1.09, 4.56) were all associated with tobacco use. There was no association between proximal stressors and tobacco use.

Conclusion

Among trans women, tobacco use prevalence was high. Tobacco use was associated with homelessness, intimate partner violence, and commercial sex work. Targeted tobacco cessation programs should account for the co-occurring stressors that trans women face.

Social Influence of E-cigarette Use among Asian Americans in California

Objectives: The use of e-cigarettes is on the rise in the United States (US). An understudied facet of e-cigarette use is the influence of social groups. The purpose of the present article is to examine the role of social groups in the use of e-cigarettes among Asian Americans. Methods: We conducted 12 semi-structured interviews of Asian Americans who use e-cigarettes living in California. Interviews were transcribed and analyzed using thematic analysis. Results: Findings showed that e-cigarette use is normalized and encouraged among peer groups and social gatherings, anecdotal success stories of their peers who were able to quit or reduce their use of combustible cigarettes using e-cigarettes were motivating, and vape shops provided a space for socialization and belonging. Conclusions: The findings illuminate that e-cigarette use is a mediator in Asian American social groups as an activity for collectivity and connection. Public health researchers and practitioners can address nicotine use or addiction among Asian Americans through group or peer targeted prevention and intervention strategies.

Smoking Intervention Practices in Texas Healthcare Centers with Sexual and Gender Minority Patients

Objectives

This study evaluated the use of evidence-based practices (EBPs) for smoking cessation in centers providing behavioral healthcare for patient populations that included some proportion of sexual and gender minorities (SGMs).

Methods

Healthcare providers from 75 healthcare centers across Texas serving SGMs with behavioral health needs participated in a survey assessing their center's tobacco control policies and practices.

Results

Nearly half (N = 36) of participating centers had a comprehensive tobacco-free workplace policy, 30.67% employed ≥1 tobacco treatment specialist, 73.91% employed ≥1 prescriber, 80.82% mandated screening for patient tobacco use at intake, and 57.53% provided a template for tobacco use assessments. Overall, 70.67% of providers asked patients about smoking status, 69.33% advised patients to quit, 64.00% assessed patients' interest in quitting, 58.67% assisted patients with quit attempts, and 36.00% arranged follow-up. Providers' ability to tailor interventions for special populations like SGMs ranged from very low/0 to very high/10 (M = 4.63 ± 2.59).

Conclusions

There are opportunities to improve policy implementation, standardization and usage of evidence-based interventions, and intervention tailoring within settings providing care to SGM patients in Texas to better address their tobacco use inequities.

Medical mistrust among women with intersecting marginalized identities: a scoping review

The purpose of this scoping review is to synthesize knowledge about medical mistrust and health among women who occupy other marginalized identities; namely women who also belong to one or more of the following social groups: people of color, people of low socioeconomic status, people with disabilities, lesbian and bisexual women, and/or women who have sex with women. This scoping review is based on the methodological framework by Arksey and O'Malley (2005. "Scoping Studies: Towards a Methodological Framework." International Journal of Social Research Methodology 8: 19-32. doi:10.1080/1364557032000119616). Specific search terms were entered into selected databases. Based on a set of inclusion criteria, articles were screened and assessed for eligibility. Data from the selected articles were extracted and summarized. Forty studies were included. Thirty-one studies used quantitative methodology, of which more than half used the Group-Based Medical Mistrust Scale. The majority of studies (84%) investigated the intersection of gender with race and ethnicity. Breast cancer and HIV combined accounted for more than half of the included studies. Of those studies that examined the relationship between medical mistrust and a health outcome or health behavior, almost all reported that medical mistrust had a deleterious impact. Medical mistrust among women with intersecting marginalized identities is worthy of further study, and there is still a dearth of knowledge in the role of medical mistrust among a wide range of subgroups of women and health domains.

Exploring Tobacco and E-Cigarette Use among Queer Adults during the Early Days of the COVID-19 Pandemic

The purpose of this narrative study is to describe the vaping and smoking characteristics of Queer people ages 18-34 before March of 2020 and to better understand how the COVID-19 pandemic has impacted those behaviors since March of 2020. In total, 31 participants were screened. Thirteen participants were screened prior to the emergence of COVID-19, and 18 were screened when study protocols transitioned to a remote setting (pre and during). Of the 27 eligible participants, a total of 25 participants completed the study. Most participants (n = 13) self-identified as male, followed by five identified as female, four self-identified as gender non-binary, and three identified as transgender. The most common sexual orientation amongst participants was gay (n = 10), with bisexual being the second-most reported. Approximately 20 Queer participants reported using cigarettes, 14 participants self-reported using electronic devices, and 11 reported using hookah. Twenty participants reported smoking ten or less, and four self-reported using 11-20 cigarettes per day. Approximately, 92% of participants (n = 23) indicate that they are using an e-cigarette and regular cigarettes, and 57% of participants (n = 12) report using one pod or cartridge per day. The three themes that emerged in this study are: (1) Queer people during COVID-19 are experiencing heightened minority stress; (2) Queer people are unfamiliar with smoking cessation; and (3) vaping and smoking are attributed to stress and anxiety. Queer participants are likely to be dual users of cigarette and vaping products. This present study provides increasing evidence that Queer people are experiencing heightened stress and anxiety and using cigarette smoking and vaping to cope during the COVID-19 pandemic.

Review: Prevalence of Addictions among Transgender and Gender Diverse Subgroups

We conducted an analysis of the prevalence of substance and behavioral addictions across different transgender and gender diverse (TGD) subgroups. We performed a scoping review using MEDLINE and Google Scholar databases and examined 12 addictions, including alcohol, nicotine, cannabis, illicit drugs, gambling, eating/food, internet, sex, love, exercise, work, and shopping. We presented prevalence rates for each addiction as a function of an individual’s gender identity (stratified into transgender females, transgender males, and gender nonconforming), and used cisgender women and men as reference groups. We included 55 studies in our final analysis, the majority of which investigated substance use disorders among TGD subgroups. Overall findings indicated that substantial differences in substance use exist among US TGD subgroups. There were far fewer publications that examined the prevalence of behavioral addictions across TGD subgroups. However, despite limited research in this area, findings still suggest that notable differences in behavioral addictions may exist between individual TGD subgroups. The conclusions of our review may provide clinicians with a better ability to screen for and treat at-risk individuals within the TGD community.

E-cigarette, cigarette, and cannabis use patterns as a function of sexual identity in a sample of Southern California young adults

PURPOSE

Sexual minority young adults report greater cigarette and cannabis use. Emerging evidence suggests this trend may extend to e-cigarettes. The current study evaluated the relationship between sexual identity and prevalence of e-cigarette, cigarette, and cannabis use and whether such associations differ by gender.

METHODS

Cross-sectional, regionally representative data of young adults (M[SD]age = 20.02 [0.60] years; n heterosexual = 1314; n bisexual = 77; n lesbian/gay = 28) from Wave III (2016) of the Southern California Children's Health Study were analyzed in 2019. Logistic regression analyses were conducted with sexual identity as the predictor and product use (never, prior, infrequent past 30-day [1-2 days], frequent past 30-day [3-5+ days]) as the outcome in separate models by substance (e-cigarettes, cigarettes, cannabis).

RESULTS

Bisexual individuals were the highest-risk sub-group for nearly all outcomes, with over five times the odds of reporting frequent past 30-day use for e-cigarettes (Odds Ratio [OR]: 6.68; 95% Confidence Interval [CI]: 2.80, 15.9), cigarettes (OR: 5.42; 95% CI: 2.37, 12.4), and cannabis (OR: 8.43; 95% CI: 4.40, 16.1) compared to heterosexual individuals. Although the sample size for lesbian/gay participants was small, bisexual (vs. lesbian/gay) participants also had greater odds of reporting prior use of nicotine products and frequent past 30-day cannabis use. A significant sexual identity × gender interaction emerged for lifetime cigarette use, wherein bisexual (vs. heterosexual) identity was only associated with greater odds of use for females (p < .01).

CONCLUSIONS

Sexual minority-related disparities in substance use among young adults appear to generalize to e-cigarettes, with bisexual young adults exhibiting especially high profiles of risk.

Worldwide relative smoking prevalence among people living with and without HIV

OBJECTIVE AND DESIGN

People living with HIV (PLH) suffer disproportionately from the chronic diseases exacerbated by smoking tobacco. We performed a systematic review and meta-analysis to establish the relative prevalence of smoking among PLH.

METHODS

We included observational studies reporting current smoking rates among PLH and comparators without HIV. We searched Medline, EMBASE, LILACS and SciELO from inception to 31 August 2019. We excluded studies that recruited participants with smoking related illness. We used a random effects model to estimate the odds ratio for current smoking in PLH and people without HIV. We used the Newcastle--Ottawa scale to assess methodological bias. We performed subgroup analysis based on sex and WHO region. We quantified heterogeneity with meta-regression and predictive distributions. PROSPERO registration:CRD42016052608.

RESULTS

We identified 6116 studies and included 37. Of 111 258 PLH compared with 10 961 217 HIV-negative participants pooled odds of smoking were 1.64 [(95% confidence interval, 95% CI: 1.45-1.85) (95% prediction interval: 0.66-4.10, I2 = 98.1%)]. Odds for men and women living with HIV were 1.68 [(95% CI: 1.44-1.95) (95% prediction interval: 0.71-3.98, I2 = 91.1%)] and 2.16 [(95% CI: 1.77-2.63) (95% prediction interval: 0.92-5.07, I2 = 81.7%)] respectively.

CONCLUSION

PLH are more likely to be smokers than people without HIV. This finding was true in subgroup analyses of men, women and in four of five WHO regions from which data were available. Meta-regression did not explain heterogeneity, which we attribute to the diversity of PLH populations worldwide. Smoking is a barrier to PLH achieving parity in life expectancy and an important covariate in studies of HIV-associated multimorbidity.

Perceptions of Marijuana Decriminalization Among Young Sexual and Gender Minorities in Chicago: An Initial Measure Validation and Test of Longitudinal Associations with Use

Background: There is a high rate of marijuana use among young sexual and gender minorities (SGM) and, as a result of recent state-level, fragmented marijuana laws, there is also likely high variability in their perceptions of marijuana decriminalization (PMD). Methods: Data came from two cohorts of young SGM (aged 16-29) in Chicago, RADAR and FAB400, recruited from 2015 to 2017 (N=1,114). We developed a measure to assess PMD among this population, performed initial validation, and assessed its relationship to longitudinal changes in patterns of marijuana use and geographic distribution. Results: In multivariable models, mean PMD score was prospectively associated with general (adjusted odds ratio [aOR]=2.00; 95% confidence interval [CI]: 1.46-2.77), but not problematic marijuana use. An increase in perceived decriminalization also predicted a significant increase in odds of general (aOR=1.67; 95% CI: 1.18-2.39) marijuana use. Significant concentrations of high PMD scores existed in across the city. Conclusion: These results suggest further study of longitudinal changes in marijuana use as decriminalization or legalization increases in the U.S. to better understand shifting trends in use.

Use of Cigarettes and E-Cigarettes/Vaping Among Transgender People: Results From the 2015 U.S. Transgender Survey

INTRODUCTION

This study examines the demographic characteristics, transgender-specific factors, and discrimination experiences associated with current cigarette smoking, e-cigarette use/vaping, and dual use in a large sample of transgender people.

METHODS

This was a secondary analysis of the 2015 U.S. Transgender Survey (n=27,715). Conducted in 2019, logistic regression models were used to estimate the AORs and 95% CIs of current smoking, e-cigarette use/vaping, and dual use among transgender people.

RESULTS

Overall, 23.6% of respondents used cigarettes, 9.3% used e-cigarettes/vaping products, and 5.2% reported dual use within the past 30 days. Visually nonconforming individuals had greater odds (cigarettes: AOR=1.49, 95% CI=1.35, 1.65; e-cigarettes/vaping: AOR=1.43, 95% CI=1.25, 1.65; dual use: AOR=1.81, 95% CI=1.52, 2.15) than visually conforming individuals. Transgender people who had disclosed their transgender identity to their social networks had greater odds of cigarette smoking (AOR=1.30, 95% CI=1.17, 1.45), e-cigarette use/vaping (AOR=1.30, 95% CI=1.12, 1.52), and dual use (AOR=1.95, 95% CI=1.61, 2.35) than individuals who were out to none or some people within their networks. Experiencing discrimination (i.e., unequal treatment, verbal harassment, or physical assault) significantly increased the odds for cigarette smoking, e-cigarette use/vaping, and dual use. Transgender people who experienced all 3 types of discrimination had 2 times greater odds of current cigarette smoking (AOR=2.06, 95% CI=1.79, 2.37) and dual use (AOR=2.17, 95% CI=1.73, 2.74) than those who had not experienced discrimination.

CONCLUSIONS

Discrimination, visual nonconformity, and being out as transgender increased the odds of cigarette smoking, e-cigarette use/vaping, and dual use. This study informs disease prevention efforts for transgender populations with increased risks for these health behaviors.

Tobacco smoking in three “left behind” subgroups: indigenous, the rainbow community and people with mental health conditions

Purpose

This paper aims to investigate the extent to which three subgroups – people with mental health conditions, people belonging to sexual minority and gender groups and Indigenous peoples – have been “left behind” by countries implementing the World Health Organization’s Framework Convention on Tobacco Control.

Design/methodology/approach

A general review of electronic bibliographical databases to provide an overview of smoking prevalence among the three groups and interventions designed specifically to reduce their smoking rates.

Findings

Although explanations and specific rates differ, two trends are consistent across all three groups. First, information reported in the past two decades suggests that smoking prevalence is disproportionately high among people with mental health conditions, and in the rainbow and indigenous communities. Second, most cessation programmes are targeted at majority politically dominant groups, missing opportunities to reduce smoking rates in these minority communities.

Research limitations/implications

There is a general dearth of data preventing detailed analysis. Better data collection efforts are required. Trials to identify effective smoking reduction interventions for marginalised groups are needed.

Social implications

It is socially unjust that these groups are being systematically ignored by tobacco control initiatives. A failure to equitably reduce tobacco harms among all groups across society has contributed to the perceived concentration of smoking in some subgroups. The increasing stigmatisation of people who smoke then adds a marginality, compounding the negative effects associated with belonging to a marginalised group. Ongoing marginalisation of these groups is an important determinant of smoking.

Originality/value

Cross-case analysis of neglected subgroups with disproportionately high smoking rates suggests social marginalisation is a shared and important determinant of smoking prevalence.

Correlates of tobacco product initiation among youth and adults in the USA: findings from the PATH Study Waves 1-3 (2013-2016)

OBJECTIVE

To report on demographic and tobacco product use correlates of tobacco product initiation (cigarettes, electronic nicotine delivery systems (ENDS), cigars, hookah and smokeless tobacco) among the US population.

DESIGN

Data were from the first three waves (2013-2016) of the Population Assessment of Tobacco and Health Study, a nationally representative, longitudinal cohort study of US youth (aged 12-17 years) and adults (aged 18+ years). Never users of at least one type of tobacco product at Wave 1 (W1, 2013/14) or Wave 2 (W2, 2014/15) were included (n=12 987 youth; n=25 116 adults). Generalised estimating equations were used to evaluate the association between demographic and tobacco product use characteristics at baseline, and tobacco product initiation at follow-up (ever, past 30 day (P30D), frequent (use on 20 or more of thepast 30 days)) over two 1-year periods (W1-W2 and W2-Wave 3).

RESULTS

Youth aged 15-17 years were more likely than youth aged 12-14 years and adults aged 18-24 years were more likely than older adults to initiate P30D tobacco use across products; non-heterosexuals were more likely than heterosexuals to initiate P30D cigarette and ENDS use. Older adults were more likely than young adults, and males were more likely than females, to be frequent users of ENDS on initiation. Ever use of another tobacco product predicted P30D initiation of each tobacco product.

DISCUSSION

Other tobacco product use and age predict P30D tobacco initiation across products whereas associations with other demographic characteristics vary by product. Continued contemporary evaluation of initiation rates within the changing tobacco product marketplace is important.

Cigarette Smoking and Its Associations with Substance Use and HIV-Related Sexual Risks among Chinese Men Who Have Sex with Men

China has the largest population of male smokers globally. Men who have sex with men (MSM) are at greater risk of cigarette smoking compared to the general population. Limited data are available regarding cigarette smoking and its associations with other health issues among Chinese MSM. Eligible MSM (n = 1100) were recruited from mainland China using an online national cross-sectional survey conducted in 2014–2015. Socio-demographic characteristics, smoking behavior, substance use, homosexual stigma and outness, HIV-related risk behavior, and HIV status were obtained. Logistic regression analyses were performed to evaluate predictors of current cigarette smoking frequency and the co-occurrence of smoking and drug use. Nearly 41% (n = 446) of participants had ever smoked cigarettes; 25% (n = 278) were current frequent smokers; and 13% (n = 138) were current infrequent smokers. Factors associated with a history of smoking included age, employment status, and monthly salary. Risk factors associated with current frequent smoking included self-identification as gay, having female sexual partners, binge drinking, drug use, higher levels of homosexual stigma, and being partially or fully “out” as gay. Adjusted multinomial analysis showed that human immunodeficiency virus (HIV) related risks, including risky sexual behaviors, lack of condom use, and a reported history of sexually transmitted infections (STIs), were associated with co-occurrence of current smoking and drug use. Cigarette smoking rates remain high among MSM in China. Cigarette smoking is associated with binge drinking, drug use, and HIV-related risks in this community. There is a clear opportunity for smoking cessation interventions to be linked with HIV and substance use prevention interventions, thereby addressing multiple health issues simultaneously for the MSM community in China.

Sexual orientation and gender identity disparities in substance use disorders during young adulthood in a United States longitudinal cohort

BACKGROUND

This study examined associations of sexual orientation and gender identity with prevalence of substance use disorders (SUDs) and co-occurring multiple SUDs in the past 12-months during young adulthood in a United States longitudinal cohort.

METHODS

Questionnaires self-administered in 2010 and 2015 assessed probable past 12-month nicotine dependence, alcohol abuse and dependence, and drug abuse and dependence among 12,428 participants of an ongoing cohort study when they were ages 20-35 years. Binary or multinomial logistic regressions using generalized estimating equations were used to estimate differences by sexual orientation and gender identity in the odds of SUDs and multiple SUDs, stratified by sex assigned at birth.

RESULTS

Compared with completely heterosexuals (CH), sexual minority (SM; i.e., mostly heterosexual, bisexual, lesbian/gay) participants were generally more likely to have a SUD, including multiple SUDs. Among participants assigned female at birth, adjusted odds ratios (AORs) for SUDs comparing SMs to CHs ranged from 1.61 to 6.97 (ps<.05); among participants assigned male at birth, AORs ranged from 1.30 to 3.08, and were statistically significant for 62% of the estimates. Apart from elevated alcohol dependence among gender minority participants assigned male at birth compared with cisgender males (AOR: 2.30; p < .05), gender identity was not associated with prevalence of SUDs.

CONCLUSIONS

Sexual and gender minority (SGM) young adults disproportionately evidence SUDs, as well as co-occurring multiple SUDs. Findings related to gender identity and bisexuals assigned male at birth should be interpreted with caution due to small sample sizes. SUD prevention and treatment efforts should focus on SGM young adults.

Tobacco, Alcohol, Drug Use, and Intimate Partner Violence Among MSM Living With HIV

Men who have sex with men (MSM) and are living with HIV have reported high rates of intimate partner violence (IPV) and substance use. We examined relationships between accumulative IPV, incidents of IPV, and numbers of substances used. One hundred twenty Taiwanese MSM living with HIV completed a cross-sectional survey. Accumulative IPV was assessed by summing the number of 15 types of IPV experienced in the previous year; substance use was measured by any use of alcohol, tobacco, or other drugs during the previous week. In multivariate analysis, IPV was not associated with tobacco use but was positively associated with alcohol and other drug use and significantly associated with the probability of using multiple substances. MSM living with HIV who experienced greater IPV were more likely to use alcohol and other drugs and were more likely to use more than one substance. Health care providers screening for IPV should also screen for substance use.

Tobacco use among lesbian, gay, bisexual and transgender young adults varies by sexual and gender identity

BACKGROUND

Research shows that tobacco products are disproportionately used by sexual and gender minorities, known collectively as those who are lesbian, gay, bisexual, and transgender (LGBT). While usage varies within this population by identity, differences in tobacco use patterns are not well understood. The present study uses evaluation data for This Free Life, a tobacco public education campaign from the FDA, to examine differences in tobacco use among LGBT young adults by subgroups based on sex at birth, gender and sexual identity.

METHODS

Data are from 4,057 18-24 LGBT young adults who completed the baseline This Free Life evaluation survey in 2016. Multivariable logistic regression models examined differences in tobacco use (cigarettes, cigars, hookah and electronic nicotine products) and poly use (2+ of any product, 2+ combustibles, at least one combustible and one noncombustible) between LGBT subgroups (cisgender gay males, cisgender bisexual males, cisgender lesbian/gay females, cisgender bisexual females and gender minorities).

RESULTS

Sexual minority females were more likely than gay males to use any tobacco product, electronic nicotine products and hookah. Cisgender bisexuals were more likely than gay males and gender minorities to use electronic nicotine products. Cisgender bisexual males were less likely than all other groups to use cigarettes. Cisgender sexual minority females were more likely than gender minorities to engage in poly use.

CONCLUSIONS

Findings suggest that sexual minority females are more likely to use tobacco than other subgroups. More research can help campaign developers better understand reasons for intragroup differences in tobacco use among LGBT subgroups.

Cigarette Smoking Among Youth at the Intersection of Sexual Orientation and Gender Identity

Purpose: The purpose of this study was to identify subgroups of sexual and gender minority (SGM) youth who are most vulnerable to tobacco use. Methods: We analyzed data from a national nonprobability sample of 11,192 SGM youth (ages 13-17). Age of cigarette initiation and current use were modeled using Cox proportional hazard and binomial regression. Sexual and gender identities were explanatory variables and the models were adjusted for ethnoracial identity and age. Results: Approximately 7% of the sample reported current smoking. Cisgender and transgender boys had higher odds of current smoking compared with cisgender and transgender girls (adjusted odds ratio [AOR] = 1.86; 95% confidence interval [CI]: 1.56-2.21). Pansexual-identified youth had higher odds of smoking (AOR = 1.33; 95% CI: 1.05-1.70) compared with gay/lesbian youth independent of gender identity. Pansexual-identified cisgender boys had the highest smoking prevalence (21.6%). Predicted probabilities were higher among transgender boys across all sexual identities, except asexual. The hazard of smoking at a younger age was greater for transgender boys compared with cisgender boys (adjusted hazard ratio [AHR] = 1.67; 95% CI: 1.43-1.94) as well as for bisexual (AHR = 1.12; 95% CI: 1.01-1.24) and pansexual (AHR = 1.17; 95% CI: 1.03-1.33) youth compared with those who identified as gay or lesbian. Conclusions: These findings suggest that transgender boys may be at higher risk for early and current cigarette use regardless of their sexual identity, whereas smoking varied more widely for youth across different sexual identities. The findings suggest that specific subgroups of SGM youth require focused attention in tobacco control research and practice.

High Rate of Discontinuation May Diminish PrEP Coverage Among Young Men Who Have Sex with Men

Understanding pre-exposure prophylaxis (PrEP) discontinuation is key to maximizing its effectiveness at the individual and population levels. Data came from the RADAR cohort study of MSM aged 16-29 years, 2015-2017. Participants included those who reported past 6-month PrEP use and discontinued its use by the interview date. Of the 197 participants who had used PrEP in the past 6 months, 65 discontinued use. Primary reasons for PrEP discontinuation included trouble getting to doctor's appointments (14, 21.5%) and issues related to insurance coverage or loss (13, 20.0%). Few (21%) who discontinued spoke to their doctor first, which has important implications for future long acting formulations.

Threefold Increase in PrEP Uptake Over Time with High Adherence Among Young Men Who Have Sex With Men in Chicago

The goal of this work is to better understand utilization and uptake of pre-exposure prophylaxis (PrEP) among young men who have sex with men (YMSM) and transgender women (TGW). We assessed trends and correlates of PrEP use and adherence across three time points of longitudinal data collection among 885 YMSM and TGW (aged 16-29) from the RADAR cohort in Chicago, 2015-2017. Past 6-month PrEP use increased across three visits: from 6.6 to 17.5%. In multivariable models, past 6-month PrEP use was significantly associated with participation in condomless sex, having more sexual partners, and older age. At least three-quarters of current PrEP users reported being ≥ 90% adherent to PrEP medication across all visits. Past 6-month PrEP use increased over time with those who participated in high-risk HIV behaviors also those most likely to have taken PrEP. As PrEP uptake continues to rise, more research will be needed to understand predictors of PrEP usage, as well as patterns of sexual behavior change following uptake.

Treatment Outcomes Associated with Quitting Cigarettes Among Sexual Minority Men Living with HIV: Antiretroviral Adherence, Engagement in Care, and Sustained HIV RNA Suppression

Cigarette smoking is particularly harmful for sexual minority men living with HIV. This study aimed to find benefits of quitting by examining relationships between smoking and sustained HIV RNA suppression, recent CD4 count, ART medication adherence, and engagement in HIV medical care. Sexual minority men (n = 346), former or current smokers, received HIV care at a community health center. Survey responses were combined with electronic health record data in adjusted regression models. Most patients were Caucasian (87%) and 148 (46%) had incomes below the poverty level and 80% had sustained HIV RNA suppression. Compared to current smokers, former smokers had increased odds of sustaining HIV RNA suppression (OR 1.89; 95% CI 1.02-3.48) of reporting > 90% adherence (OR 2.25; 95% CI 1.21-4.17), and were less likely to miss appointments (OR 0.37; 95% CI 0.17-0.82). Heavier smokers (OR 0.36; 95% CI 0.17-0.77) and patients who smoked the longest (OR 0.31; 95% CI 0.14-0.68) had reduced odds of sustaining HIV RNA suppression. Smoking assessment, treatment, and referral could augment HIV outcomes for sexual minority men with HIV.
