Waterpipe tobacco smoking among sexual minorities in the United States: Evidence from the National Adult Tobacco Survey (2012-2014)

ObjectiveThe current study examined differences in waterpipe smoking (both lifetime and current) comparing sexual minority populations - those identifying with lesbian, gay, or bisexual identity - to their heterosexual counterparts using a nationally representative dataset.MethodsThe current study used pooled data from the 2012–2013 & 2013–2014 National Adult Tobacco Survey (NATS). Log-Poisson multivariable regression models were deployed to determine the prevalence of waterpipe smoking behavior among sexual minority individuals controlling for sociodemographic characteristics and stratified by current gender status.ResultsIn fully-adjusted models assessing lifetime WTS, lesbian/gay and bisexual respondents reported higher prevalence of WTS compared to their heterosexual counterparts. This trend held true in gender-stratified models among gay men [gay men: PR 1.25, 95%CI [1.06, 1.47] and women ([lesbians: PR 1.38, 95%CI [1.12, 1.69] and bisexual women: 1.69, 95%CI [1.45, 1.97]). In fully-adjusted models assessing current WTS, lesbian/gay and bisexual respondents reported higher risk of WTS compared to their heterosexual counterparts. This trend held true in gender-stratified models, only for among gay men [gay men: PR 1.56, 95%CI [1.18, 2.05] and bisexual women: 2.38, 95%CI [1.84, 3.09]).ConclusionsAmong the US general adult population, sexual minorities exhibited increased prevalence of current waterpipe smoking compared to their heterosexual counterparts. This pattern is also shaped by gender and variation of sexual orientation identification (e.g., lesbian/gay vs. bisexual). This warrants development of tailored interventions aimed at decreasing waterpipe smoking among sexual minority populations.     

Regular past year cannabis use in women veterans and associations with sexual trauma

IntroductionThis study sought to describe the prevalence of regular past year cannabis use (i.e., at least monthly use) in women veterans, to characterize women veterans reporting this level of use, and to examine the independent contributions of sexual trauma across the lifespan on regular past year cannabis use.MethodsA national online survey on women veterans' health, with targeted oversampling of lesbian and bisexual women, collected data from US armed forces women veterans, 18 or older, living in the US (N = 636).ResultsEleven percent of women reported regular cannabis use (5% heterosexual women; 21% lesbian/bisexual women). In bivariate analysis, identifying as a sexual and/or racial ethnic minority, younger age, being unmarried, reporting lower income, receiving VA services, smoking tobacco, and screening positive for alcohol misuse were positively associated with regular cannabis use. Additionally, a greater percentage of cannabis users reported experiencing childhood and adult sexual trauma and screened positive for posttraumatic stress disorder (PTSD) when compared to peers who did not use any drugs. In a multivariate model, the number of life eras women endorsed experiencing sexual trauma was significantly associated with regular cannabis use even when adjusting for demographic variables and PTSD symptoms.ConclusionsAmong women veterans, regular cannabis use is fairly common among those who are sexual and racial/ethnic minorities, younger, unmarried, receiving VA services, and reporting alcohol or tobacco use, PTSD symptoms, and/or multiple sexual traumas across the lifespan. Screening and assessment may be important to consider in healthcare settings serving this veteran population.     

Sexual identity and substance use among undergraduate students

This study examined the association between sexual identity and use of alcohol and other drugs (AOD) among college undergraduate students. A survey regarding AOD use was administered to a random sample of 3607 undergraduate students. The sample included 65 self‐identified lesbian or bisexual (LB) women and 54 self‐identified gay or bisexual (GB) men. Multivariate logistic regression indicated that while alcohol use did not differ for LB and heterosexual women, LB women were significantly more likely to experience certain AOD‐related consequences, smoke cigarettes, and use marijuana, ecstasy, and other drugs. GB men were significantly less likely than heterosexual men to drink heavily but were more likely to use some drugs. These findings provide evidence that sexual identity is an important predictor of AOD use among undergraduate students. These findings support the need for continued research and intervention efforts that target LGB collegians.

Association of Alcohol Misuse With Sexual Identity and Sexual Behavior in Women Veterans

Background: Sexual minority women report greater alcohol misuse than heterosexual women in the general population, with more pronounced differences found among younger age groups. It is unknown whether these differences exist among women veterans. Objective: We evaluated differences in alcohol misuse across two dimensions of sexual orientation (identity and behavior) among women veterans, and examined whether these differences were modified by age. Methods: Women veterans were recruited via the internet to participate in an online survey. Participants provided information on their self-reported sexual identity and behavior and responded to the validated 3-item Alcohol Use Disorders Identification Test-Consumption questionnaire (AUDIT-C). Regression models were used to compare the prevalence of alcohol misuse (AUDIT-C ≥ 3) and severity (AUDIT-C scores) across sexual identity and behavior and to test effect modification by age. Results: Among the 702 participants (36% lesbian/bisexual), prevalence and severity of alcohol misuse varied by both sexual identity and behavior, but there were significant interactions with age. Prevalence and severity of alcohol misuse were higher among relatively younger self-identified lesbians compared to heterosexual women. Similarly, both prevalence and severity of alcohol misuse were generally higher among younger women who had any sex with women compared to those who had sex only with men. Conclusions/Importance: In this online study of women veterans, younger sexual minority women were more likely to screen positive for alcohol misuse, and they had more severe alcohol misuse, than their heterosexual counterparts. Prevention and treatment efforts focused specifically on sexual minority women veterans may be needed.     

International Differences in Alcohol Use According to Sexual Orientation

ABSTRACT

Most research on sexual orientation and alcohol use in the United States has found higher rates of alcohol use and abuse among gay men and lesbians. Studies from other countries have found smaller or no differences between sexual minority and heterosexual women and men. The present study used general population survey data from 14 countries to examine high-volume and risky single-occasion drinking by sexual orientation. Data from 248 gay men and lesbians and 3720 heterosexuals were analyzed in a case-control design. In several countries partnered or recently partnered gay men and lesbians had no greater risk of heavy drinking or engaging in heavy drinking than heterosexual controls. Only lesbians in North America showed higher risk for both indicators. Future general population health research should include larger samples of gays and lesbians and use more comprehensive measures of sexual orientation for investigating the prevalence of health risk factors.     

Sexual identity and prevalence of alcohol and other drug use among Australians in the general population

BackgroundInternational research assessing differences in the prevalence of alcohol and other drug (AOD) use among Lesbian Gay Bisexual and Transgender (LGBTI) and heterosexual populations shows elevated prevalence rates of substance use among LGBTI people. To date no research has been published investigating these differences at a population level among both men and women in Australia.MethodsThe 2013 National Drug Strategy Household Survey, a multistage stratified population sample collecting data on AOD use in the Australian population over 14 years of age, was analysed for differences between gay and bisexual (GB) men and lesbian/gay and bisexual (LGB) women and their heterosexual counterparts in: (1) the prevalence of lifetime and past year tobacco and AOD use; (2) age of initiation of tobacco and AOD use; and (3) frequency of alcohol and cannabis use, and history of AOD treatment.ResultsThere were elevated rates of past year cannabis (22.4%), ecstasy (11.8%) and methamphetamine (9.7%) use among GB men compared to heterosexual men (12.4%, 2.9% and 2.5%). LGB women also reported elevated rates of past year use (tobacco – 23.7%; cannabis – 24.6%) compared to heterosexual women (10.6% and 7.1%). LGB women initiated tobacco (15.2 years) and alcohol (15.5 years) at an earlier age than heterosexual women (16.6 and 17.7 years), and were significantly more likely to report daily alcohol consumption (OR 3.2, 95% CI: 2.1, 5.1), and weekly or more frequent cannabis use (OR 1.7, 95%CI: 1.1, 3.1).ConclusionsThese findings are indicative of the need for more responsive and targeted AOD harm reduction and treatment services for LGBTI communities in Australia. Of concern is the elevated risk among LGB women for earlier initiation of substance use, and the development of problematic consumption patterns. Further research, investigating the risk and protective factors for AOD use among LGB women is warranted.     

Substance Use and Sexual Orientation among East and Southeast Asian Adolescents in Canada

The purpose of this study was to examine the relationship between substance use and sexual orientation among Asian adolescents in Canada. We analyzed an East- and Southeast-Asian subsample of a province-wide, school-based survey (weighted N = 51,349). Compared to heterosexual adolescents of the same gender, gay, lesbian, bisexual, and mostly heterosexual adolescents were more likely to use alcohol, marijuana, or other illicit drugs. Particularly, sexual minority girls were at increased risk for substance use. The findings suggest the need for substance use prevention interventions that are sensitive to gender, sexual orientation, and culture.     

Elevated alcohol and sexual risk behaviors among young Thai lesbian/bisexual women

BackgroundLittle empirical data have been published about drinking or sexual behaviors among Thai lesbians. We examine the association of sexual identity with established indicators of alcohol- and sexual-related health behaviors among female bar patrons.MethodsWe conducted a cross-sectional study among women (N = 121) aged 18–24 who frequented popular drinking establishments in Chiang Mai, Thailand. We used general linear modeling techniques to estimate associations between sexual identity and positive alcohol expectancy, harmful drinking, age at sexual debut, and number of lifetime sexual partners.ResultsNearly one-third of women aged 18–24 recruited from Chiang Mai drinking venues identified as lesbian/bisexual. As compared to their heterosexual counterparts, lesbian/bisexuals reported higher positive alcohol expectancy scores, more harmful drinking, earlier age at sexual debut, and higher number of lifetime sexual partners. In adjusted models, lesbian/bisexual identity was associated with higher positive alcohol expectancy (β = 1.94 points; 95% CI: 0.75, 3.13), earlier age at sexual debut (β = ?0.85 years; 95% CI: ?1.46, ?0.23), and higher number of lifetime sexual partners (rate ratio = 1.70; 95% CI: 1.22, 2.37).ConclusionLesbian/bisexual women in this study engaged in multiple behaviors that are potentially harmful to health, which may in turn place this group at heightened risk for alcohol abuse and sexually transmitted infections in Thailand. The clustering of alcohol- and sexual-related risk behaviors, and its consequences for health outcomes in this population, should be explored in future research and may be an important point of intervention.     

Differences in club drug use between heterosexual and lesbian/bisexual females

Although there has been much empirical research documenting current trends in club drug use among gay and bisexual men, little research has addressed the variance among lesbian, bisexual, or heterosexual women. Using data collected through time-space sampling from dance clubs in New York City during 2005 (N=1104), this study explored sexual identity variance among women in the reported use of six club drugs: methamphetamine, cocaine, MDMA, ketamine, GHB, and LSD. Significant differences were found in that younger women were more likely to be active club drug users. Lesbian and bisexual women reported significantly higher lifetime rates of ecstasy, cocaine, methamphetamine, and LSD use compared to heterosexual women. These data suggest a need to better understand the influence of sexual orientation and sexual culture in relation to club drug use and to tailor health promotion efforts to meet the needs of various groups of club drug using women.
