RESUMO

INTRODUCTION: Emerging research has found that some young adults report vaping nicotine to control appetite and lose weight. Yet, there is little research on how young adults use vaping to manage weight, where they learn about weight-motivated vaping, and the role that food and weight motivations play in decisions to vape. METHODS: We conducted one-on-one qualitative interviews with young adults aged 18-25 years old in Los Angeles, California (N = 62) from June 2018 to June 2019, who self-reported using e-cigarettes on a weekly basis or more for at least 5 months prior to study enrollment. Interviews examined participants' thoughts, feelings, and experiences related to e-cigarette use, including their understanding of the relation of vaping with eating behaviors and weight management. We analyzed the interviews using the rigorous and accelerated data reduction (RADaR) technique. RESULTS: Participants reported pairing nicotine vaping with caffeinated beverages like coffee, pop/soda, tea, and after every meal (like patterns of combustible cigarette use). Participants also reported vaping nicotine as a tool to avoid binge eating and increase concentration while studying. Reports of vaping effecting appetite and eating behaviors also emerged. Vaping nicotine to suppress appetite and/or achieve weight loss was often reported in conjunction with an eating disorder. Participants reported learning about weight-motivated vaping from peers or deducing from cigarette effects and their own experiences with nicotine. Others mentioned controlling food cravings by vaping a similar e-liquid flavor. CONCLUSION: Nicotine vaping was used as a tool to control weight and suppress appetite, paralleling food- and weight-related behaviors associated with cigarette use. Findings suggest a need for targeted interventions that address the role of nicotine vaping in eating/weight-related behaviors.

RESUMO

INTRODUCTION: Previous studies suggest that young adults who vape nicotine experience difficulty when answering survey items assessing the quantity of vaping. The current study asked young adults who vape to provide suggestions for improving the scientific measurement of vaping. AIMS AND METHODS: We conducted semi-structured qualitative interviews with 62 young adults who vape in Los Angeles, California between June 2018 and June 2019. We analyzed participants' responses to the following question: "What do you think is the best way for us to understand how much people vape?" using thematic content analysis. RESULTS: We identified two major themes: (1) challenges stemming from differences between the way researchers query about vaping and how individuals self-monitor vaping frequency, and (2) insights for future measurement of vaping. Participants reported that challenges of accurately quantifying vaping were due to inherently hard-to-answer questions (eg, puffs per day), lack of awareness of or not actively monitoring consumption of vaping products, or because vaping behaviors vary considerably between and within individuals over time, making "on-average" questions challenging. Participants discussed ideas for improving survey measures that could accurately assess vaping quantity, including querying about the type of device used, and frequency of replenishment of nicotine solutions. CONCLUSIONS: Existing vaping behavior survey measures may not accurately capture the quantity of vaping as they differ from how (or if) participants track their own vaping consumption patterns. While continued research is needed to optimally refine survey measures on vaping consumption, future measures may better align with vapers' self-monitoring by including questions on device-type and replenishment frequency. IMPLICATIONS: The present study provides insights regarding the variability that exists between vaping quantity measurements utilized by researchers and individuals who consume e-cigarettes. The qualitative data analyzed for this study support previous reports of difficulties faced by vapers when asked questions by researchers related to their vaping behavior. Furthermore, the present findings suggest the direction for the future development of accurate measurements of vaping frequency.

RESUMO

INTRODUCTION: Young adult never-smokers who vape are at elevated risk of initiating cigarettes, while young adults who smoke often begin vaping to substitute or reduce cigarette use. Reasons underlying different use patterns of tobacco products are not well-understood. AIMS AND METHODS: We conducted 1-on-1 qualitative interviews with young adults (N = 62) who vape in Los Angeles, California from June 2018 to June 2019. Participants were 18-25 years old (79% male; racially/ethnically diverse) and self-reported vaping ≥1x/week. We used a semi-structured interview guide and applied thematic analysis method to analyze data. RESULTS: Young adults initiated vaping due to peer socialization and e-liquid flavor novelty. They often reported vaping (after first smoking) due to a belief that e-cigarettes are healthier, social pressure to quit smoking, and convenience of use. Participants reported smoking (after first vaping) when traveling outside of the United States where vaping products were less accessible, and cigarettes were normative. Many of the personal narratives described patterns of dual and cyclical use, which was often attributed to nicotine dependence and cost, or described as dependent upon the current environment (eg, at a party). CONCLUSIONS: The current study characterizes nicotine use trajectories and reasons why young adults vape, and smoke cigarettes. Dual and cyclical use of both e-cigarettes and cigarettes was common; this pattern of use should be considered in policy and prevention work to address nicotine dependence among young people. IMPLICATIONS: We display findings from the current study in a model depicting common trajectories of nicotine use, along with reasons for initiation, transitions between products, and dual/cyclical e-cigarette and combustible cigarette use.

RESUMO

BACKGROUND: The introduction of illicitly made fentanyl in the United States has slowly replaced heroin. New illicit drugs are often associated with changes in frequency and modes of administration. We assessed changes in injection frequency and smoking fentanyl in the new era of fentanyl availability in San Francisco. METHODS: We used targeted sampling to recruit 395 people who inject drugs (PWID) into an observational cohort study in San Francisco 2018-2020. We assessed changes in injection frequency, opioid injection frequency and fentanyl smoking frequency in four six-month periods. We also conducted qualitative interviews with PWID asking about motivations for injecting and smoking opioids. RESULTS: The median number of past-month injections steadily decreased by semi-annual calendar year from 92 injections in July to December 2018 to 17 injections in January to June 2020. The rate of opioid injections reduced by half (Adjusted Incidence Rate Ratio = 0.41; 95 % Confidence Interval = 0.25, 0.70; p < 0.01). The number of days smoking fentanyl was associated with fewer number of injections (X2(2) = 11.0; p < 0.01). Qualitative interviews revealed that PWID's motivation for switching from injecting tar heroin to smoking fentanyl was related to difficulties accessing veins. After switching to smoking fentanyl, they noticed many benefits including how the drug felt, improved health, fewer financial constraints, and reduced stigma. CONCLUSION: Between 2018 and 2020, there was a shift from injecting tar heroin to smoking fentanyl in San Francisco. Reductions in injection of illicit drugs may offer public health benefit if it reduces risk of blood-borne viruses, abscesses and soft-tissue infections, and infective endocarditis.

RESUMO

BACKGROUND: While rates of e-cigarette use ('vaping') continue to potentiate concern, there is limited data on common symptoms of e-cigarette dependence among young adults who vape. This study sought to critically explore how young adults experience, manifest, and conceptualize vaping dependence symptoms in their everyday lives. METHODS: Between June 2018 and 2019, in-depth qualitative interviews were conducted with 62 young adults who use e-cigarettes (aged 18-25) and live in Southern California. We explored participants' product preferences, daily e-cigarette use patterns, vaping history, withdrawal experiences, and quit attempts or periods of cessation. We used a thematic analysis approach to interpret the transcripts. RESULTS: Young adults discussed nine dimensions of vaping dependence that were organized into two categories: 1) general nicotine dependence symptoms, and 2) unique dependence symptoms related to vaping. Nicotine dependence symptoms included cravings and urgency to use, increased use to achieve desired effects, and unsuccessful quit attempts and withdrawal. Symptoms unique to vaping dependence included greater nicotine consumption due to accessibility and lack of restrictions, habitual vaping, inability to track vaping frequency, immediate gratification and comfort, social acceptability and norms, and awareness of vaping dependency. CONCLUSIONS: In addition to nicotine dependence symptoms that have been characterized for other tobacco products, young adult e-cigarette users described unique symptoms of vaping dependence that necessitate the need for more refined measures. All dimensions of vaping dependence should be considered in discussions of policies as well as treatment and education efforts intended to protect young people from e-cigarette dependence.

RESUMO

OBJECTIVE: Cannabis motivations have been studied extensively among patients of medicinal cannabis dispensaries, but less is known about motivations in community samples of opioid-using people who inject drugs. Our objective is to describe cannabis use motivations associated with self-treatment of physical pain, emotional issues, and as an opioid substitute. METHODS: Data come from 6-month follow-up interviews with people who inject drugs who participated in a study on the efficacy of an injection initiation prevention intervention in Los Angeles and San Francisco, California from 2016-18. The analytic sample consists of 387 people who inject drugs who reported past-month cannabis use. We developed multivariable logistic regression models by reported cannabis use motivations: physical pain relief, emotional problems, and opioid substitute. RESULTS: The most common cannabis use motivations reported by people who inject drugs was to "get high," relieve physical pain and emotional problems, and reduce opioid use. In separate multivariate models, using cannabis for physical pain relief was associated with higher odds of using cannabis as a substitute for opioids; cannabis for emotional problems was associated with being diagnosed with depression; and cannabis as a substitute for opioids was associated with non-prescribed, non-injection methadone use. CONCLUSION: People who inject drugs reported using cannabis for health-related motivations. This motivation aligns with health needs and suggests the acceptability of cannabis use for health reasons in this population. Studies to determine the medical effectiveness of cannabis products for these common health and mental health needs among people who inject drugs are needed.

RESUMO

OBJECTIVES: Research is limited on tobacco retailers' perceptions of the Food and Drug Administration's (FDA) tobacco regulatory authority overall, and less exists related to retailers in predominantly African-American or other racial/ethnic neighborhoods. We assessed differences in perceptions of the FDA's tobacco regulatory authority and barriers to compliance among retailers in African-American and non-African-American neighborhoods in Los Angeles, California. METHODS: Overall, 700 tobacco retailer interviews assessed demographic characteristics and perceptions of the FDA. RESULTS: Retailers in African-American neighborhoods self-identified as Hispanic/Latino (43.9% vs 39.6% non-African-American), African-American (21.2% vs 2.6% non-African-American) or Asian (19.7% vs 19.5% non-African-American). Retailers in African-American neighborhoods were significantly less likely to perceive the FDA as a trustworthy source (p = .03; vs non-African-American), but more likely to report that they do not know the federal rules (p = .002), do not understand the federal rules (p = .004), and that tobacco companies encourage them not to follow the federal rules (p = .04). CONCLUSIONS: Tobacco control agencies can use this information about retailer perceptions to design education/training materials in order to increase trust, mitigate barriers, and enhance compliance.

RESUMO

BACKGROUND: Insufficient recruitment of participants remains a critical roadblock to successful clinical research, particularly clinical trials. Social media provide new ways for connecting potential participants with research opportunities. Researchers suggest that the social network Twitter may serve as a rich avenue for exploring how patients communicate about their health issues and increasing enrollment in cancer clinical trials. However, there is a lack of evidence that Twitter offers practical utility and impact. OBJECTIVE: This pilot study aimed to examine the feasibility and impact of using Twitter monitoring data (ie, user activity and their conversations about cancer-related conditions and concerns expressed by Twitter users in Los Angeles County) as a tool for enhancing clinical trial recruitment at a comprehensive cancer center. METHODS: We will conduct a mixed-methods interrupted time series study design with a before-and-after social media recruitment intervention. On the basis of a preliminary analysis of eligible trials, we plan to onboard at least 84 clinical trials across 6 disease categories: breast cancer, colon cancer, kidney cancer, lymphoma, non-small cell lung cancer, and prostate cancer that are open to accrual at the University of Southern California (USC) Norris Comprehensive Cancer Center. We will monitor messages about these 6 cancer conditions posted by Twitter users in Los Angeles County. Recruitment for the trials will occur through the Twitter account (@USCTrials). Primary study outcomes-feasibility and acceptance of the social media intervention among targeted Twitter users and the study teams of the onboarded trials-will be assessed using qualitative interviews and the 4-point Likert scale and by calculating the proportion of targeted Twitter users who engaged with outreach messages. Second, impact of the social media intervention will be measured by calculating the proportion of enrollees in trials. The enrollment rate will be compared between the active intervention period and the prior 10 months as historical control for each disease trial group. This study has been funded by the National Center for Advancing Translational Science through a Clinical and Translational Science Award. Study approval was obtained from the clinical investigations committee at USC Norris and the institutional review board at USC. RESULTS: Recruitment on Twitter started in February 2018. Data collection will be completed in November 2018. CONCLUSIONS: This pilot project will provide preliminary data and practical insight into the application of publicly available Twitter data to identify and recruit clinical trial participants across 6 cancer disease types. We will shed light on the acceptance of the social media intervention among Twitter users and study team members of the onboarded trials. If successful, the findings will inform a multisite randomized controlled trial to determine the efficacy of the social media intervention across different locations and populations.

RESUMO

Background HIV testing, treatment initiation and treatment adherence have been emphasised for Black men who have sex with men (BMSM). However, many BMSM do not get tested, obtain HIV treatment or adhere to treatment. It is essential to highlight barriers to HIV testing, treatment adherence and the ideal components for an intervention: peer mentors, socioeconomic resources and participant incentives. METHODS: Five focus groups (n=24) were conducted among HIV-negative and HIV-positive BMSM aged ≥18 years in Los Angeles, California, USA to explore motivations and barriers to testing and treatment and the components of an ideal, culturally competent HIV testing intervention for BMSM. RESULTS: Barriers to HIV testing included fear and stigma associated with discovering a HIV-positive status and drug use. Motivations for testing included experiencing symptoms, beginning new relationships, perceptions of risk and peer mentors. CONCLUSIONS: Future HIV prevention and treatment efforts should consider these components to improve health outcomes among BMSM.

RESUMO

BACKGROUND: Heroin use is increasing in the US. Heroin use may predispose users towards injection routes of drug administration as compared to other illicit substances. OBJECTIVE: To explore the relationship between heroin use and drug injection, we compared time from first use to first injection (referred to as time to injection onset by drug [TTIOD]) of heroin, methamphetamine/speed, cocaine, and crack cocaine among people who inject drugs (PWID). METHODS: Age of first use and first injection by drug was collected from 776 PWID. Survival analyses were used to determine TTIOD and to examine demographic factors associated with TTIOD. Cox regression analysis was used to determine demographic factors associated with drug-specific injection onset. RESULTS: The eventual injection onset rate by the drug was 99% for participants who used heroin, 85% for participants who used methamphetamine/speed, 80% for participants who used powder cocaine, and 38% for participants who used crack cocaine. Hazard ratios for injection use within one year of first use by drug were: 1.37 (median survival time [MST] = 0.61 years) for heroin, 0.66 (MST = 1.10 years) for methamphetamine/speed, 0.50 (MST = 2.93 years) for powder cocaine, and 0.12 (MST = 39.59 years) for crack cocaine. Demographic differences in TTIOD were found for each drug. Demographic differences were found for eventual injection by drug for all substances except heroin. CONCLUSION: Among PWID, heroin use was associated with a more rapid transition to injection and a higher rate of eventual heroin injection regardless of demographics. More robust, innovative efforts to reduce heroin use and prevent injection initiation are urgently needed.

RESUMO

OBJECTIVE: Blacks/African Americans have experienced direct public health harm from US governmental agencies (eg, police violence, Tuskegee syphilis experiment) that may influence perceptions of the trustworthiness of government messages regarding tobacco products. Consequently, we sought to explore Black Americans' awareness of and trust in the FDA's role as a tobacco regulator. METHODS: Data were from 2 focus groups conducted with a purposive sample of 23 Black stakeholders in Los Angeles, California. Discussions were audio-recorded and transcribed verbatim for analysis. RESULTS: Although most (N = 14; 61%) participants were aware of the FDA's role as a tobacco regulator, they all noted that the Black community in Los Angeles is not aware. Recurrent across the focus groups were discussions about distrust in the FDA with 4 main contributing factors: (1) that the FDA is influenced by the tobacco, agricultural, and pharmaceutical industries; (2) that the FDA is influenced by money and politics; (3) that the FDA is a bureaucracy exercising monopoly and power; and (4) that the FDA lacks technical capacity and competence to regulate tobacco products. CONCLUSIONS: Study findings highlight opportunities for the FDA to increase awareness and build trust in their tobacco regulatory role through communication campaigns targeted at Black Americans, and community engagement with Black stakeholders.

RESUMO

The current study utilized the intersectionality framework to explore whether smoking outcome expectancies (i.e., cognitions about the anticipated effects of smoking) were predicted by gender and ethnicity, and the gender-by-ethnicity interaction. In a cross-sectional design, daily smokers from the general community (32.2% women; non-Hispanic African American [n = 175], non-Hispanic White [n = 109], or Hispanic [n = 26]) completed self-report measures on smoking expectancies and other co-factors. Results showed that women reported greater negative reinforcement (i.e., anticipated smoking-induced negative affect reduction) and weight control (i.e., anticipated smoking-induced appetite/weight suppression) expectancies than men. Hispanic (vs. African American or White) smokers endorsed greater negative reinforcement expectancies. A gender-by-ethnicity interaction was found for weight control expectancies, such that White women reported greater weight control expectancies than White men, but no gender differences among African American and Hispanic smokers were found. These findings suggest that gender, ethnicity, and their intersectionality should be considered in research on cognitive mechanisms that may contribute to tobacco-related health disparities.

RESUMO

BACKGROUND: Clinical, experimental, and ethnographic research suggests that cannabis may be used to help manage pain. Ethnographic research has revealed that some people are using cannabis to temper their illicit opioid use. We seek to learn if there is an association between cannabis use and the frequency of nonmedical opioid use among people who inject drugs (PWID). METHODS: PWID were recruited using targeted sampling methods in Los Angeles and San Francisco, California, 2011-2013. We limited analysis to people who used opioids in past 30 days (N=653). OUTCOME VARIABLE: number of times used any opioids non-medically in past 30 days. Explanatory variable: any cannabis use past 30 days. STATISTICS: multivariable linear regression with a log-transformed outcome variable. RESULTS: About half reported cannabis use in the past 30 days. The mean and median number of times using opioids in past 30 days were significantly lower for people who used cannabis than those who did not use cannabis (mean: 58.3 vs. 76.4 times; median: 30 vs 60 times, respectively; p<0.003). In multivariable analysis, people who used cannabis used opioids less often than those who did not use cannabis (Beta: -0.346; 95% confidence interval: -0.575, -0.116; p<0.003). CONCLUSIONS: There is a statistical association between recent cannabis use and lower frequency of nonmedical opioid use among PWID. This may suggest that PWID use cannabis to reduce their pain and/or nonmedical use of opioids. However, more research, including prospective longitudinal studies, is needed to determine the validity of these findings.

RESUMO

BACKGROUND: Little is known about the consistency of information provided by people who inject drugs (PWID) during quantitative and qualitative interviews in mixed methods studies. OBJECTIVES: We illustrate the use of the intraclass correlation coefficient, descriptive statistics, and regression to assess the consistency of information provided during a mixed methods study of PWID living in Los Angeles and San Francisco, California, USA. METHODS: Age of first use of heroin, methamphetamine, marijuana, powder cocaine, and crack cocaine and first injection of heroin, methamphetamine, and powder cocaine were collected during an interviewer administered computer-assisted personal interview followed by an in-depth qualitative interview (n = 102). RESULTS: Participants were 63% male, racially/ethnically diverse. 80.4% between the ages of 40 and 60 years old, 89% US-born, and 57% homeless. Consistency of self-reported data was adequate for most drug use events. Exact concordance between quantitative and qualitative measures of age of onset ranged from 18.2-50%. Event ordering was consistent across qualitative and quantitative results for 90.2% of participants. Analyses indicated that age of onset for heroin use, heroin injection, and injection of any drug was significantly lower when assessed by qualitative methods as compared to quantitative methods. CONCLUSION: While inconsistency will emerge during mixed method studies, confidence in the timing and ordering of major types of events such as drug initiation episodes appear to be warranted.

RESUMO

BACKGROUND: Among persons who inject drugs (PWID), polydrug use (the practice of mixing multiple drugs/alcohol sequentially or simultaneously) increases risk for HIV transmission and unintentional overdose deaths. Research has shown local drug markets influence drug use practices. However, little is known about the impact of drug mixing in markets dominated by black tar heroin and methamphetamine, such as the western United States. METHODS: Data were collected through an ongoing longitudinal study examining drug use, risk behavior, and health status among PWID. Latent class analysis (LCA) was used to identify patterns of substance use (heroin, methamphetamine, prescription drugs, alcohol, and marijuana) via multiple administration routes (injecting, smoking, and swallowing). Logistic regression was used to identify behaviors and health indicators associated with drug use class. RESULTS: The sample included 511 mostly white (51.5%) males (73.8%), with mean age of 43.5 years. Two distinct classes of drug users predominated: methamphetamine by multiple routes (51%) and heroin by injection (49%). In multivariable logistic regression, class membership was associated with age, race, and housing status. PWID who were HIV-seropositive and reported prior sexually transmitted infections had increased odds of belonging to the methamphetamine class. Those who were HCV positive and reported previous opioid overdose had an increased odds of being in the primarily heroin injection class (all P-values < .05). CONCLUSION: Risk behaviors and health outcomes differed between PWID who primarily inject heroin vs. those who use methamphetamine. The findings suggest that in a region where PWID mainly use black tar heroin or methamphetamine, interventions tailored to sub-populations of PWID could improve effectiveness.

RESUMO

BACKGROUND: Historically, the alcohol and tobacco industries have been the biggest users of outdoor advertising. However, the 1999 Master Settlement Agreement (MSA) outlawed tobacco billboards and transit furniture (e.g., bus, bench) ads, and the Outdoor Advertising Association of America (OAAA) has pledged to voluntarily eliminate ads for alcohol and tobacco within 500 feet of schools, playgrounds, and churches. METHODS: Outdoor advertisements were observed (2004-2005) in a sample of urban census tracts (106 in pre-Katrina southern Louisiana and 114 in Los Angeles County) to evaluate tobacco and alcohol advertisers' compliance with the MSA and the OAAA Code of Industry Principles. Data were analyzed in 2007-2008. RESULTS: More than one in four tobacco ads in Louisiana failed to comply with the MSA. In Los Angeles, 37% of alcohol ads and 25% of tobacco ads were located within 500 feet of a school, playground, or church; in Louisiana, roughly one in five ads promoting alcohol or tobacco fell within this distance. In Los Angeles, low-income status and the presence of a freeway in the tract were associated with 40% more alcohol and tobacco billboards near children. In Louisiana, each additional major roadway-mile was associated with 4% more tobacco ads-in violation of MSA-and 7% more small ads near schools, playgrounds, and churches; city jurisdiction accounted for 55% of MSA violations and more than 70% of the violations of OAAA guidelines. CONCLUSIONS: Cities must be empowered to deal locally with violations of the MSA. Legislation may be needed to force advertisers to honor their pledge to protect children from alcohol and tobacco ads.

RESUMO

Latinos in the United States are disproportionately impacted by HIV/AIDS. They accounted for 20.4% of the AIDS cases reported in 2003, despite the fact that they represent 13.3% of the civilian non-institutional population of the United States. Thus it is important to identify ways to increase HIV testing among Latinos engaging in high risk behaviors. One approach that has been proposed for increasing HIV testing is the "bundling" of HIV prevention interventions with other relevant services. This study examined whether offering HIV testing with screening for other conditions would increase HIV testing among Latino men who frequent gay bars. A cross-sectional survey of 394 Latino men was conducted at both urban and suburban gay bars. Overall, no statistical differences were found in the number of individuals who took the HIV test or who tested HIV-positive when the HIV test was offered with screening for other conditions (alcohol problems, drug dependence, depression, syphilis, gonorrhea and chlamydia) compared to when it was offered by itself. However, multivariate analysis found that three groups of Latino men were more likely to test for HIV when it was bundled with other tests: those who reported having sex primarily with women, those with other risk factors that could also be tested through a bundled test approach, and those who were clients of the suburban gay bar that was farthest from a large geographical gay community. Further studies of bundled HIV testing should be conducted with other key subpopulations that may be more willing to take an HIV test when it is offered with other relevant tests than when offered by itself.

RESUMO

We conducted a literature search to review studies that presented quantitative data on sexually transmitted disease (STD) screening in non-traditional settings in the United States. We examined the studies for evidence of the feasibility of screening, population size reached, acceptability, yield, and potential for contributing to STD control. We found 17 studies in jails, eight in emergency room, five in schools and 15 in other community settings. Jail-based and emergency room-based STD screenings have the highest yields and the largest numbers screened and thus hold significant promise as settings for routine STD screening. More research needs to be done in school and community settings to better identify their potential.

RESUMO

BACKGROUND: The authors describe and compare drinking patterns among malt liquor beer (MLB), regular beer (RB), and hard liquor (HL) drinkers in a low-income, racial/ethnic minority community. METHODS: Drinkers were recruited from randomly selected alcohol outlets in South Los Angeles. Respondents were assessed on sociodemographic characteristics, alcohol use history, drinking patterns, and drinking context among other items in a face-to-face interview with research staff. RESULTS: Three hundred twenty-nine drinkers were interviewed, of whom 297 reported drinking MLB, RB, or HL brands of alcohol most often in the past 90 days. This subsample was 88% African-American, 72% male, and 35% unemployed. As compared with RB and HL drinkers, MLB drinkers were more likely to be homeless, to receive public assistance for housing, and to be unemployed. MLB drinkers also reported significantly higher rates of daily or near-daily drinking (74%, as compared with 48% for RB and 29% for HL) of drinks per day on drinking days (5.2, as compared with 4.2 for RB and 3.1 for HL), and daily average ethanol consumption (6.97 oz, as compared with 2.13 oz for RB drinkers and 6.13 oz for HL drinkers). In multinomial regression analysis that controlled for potential confounders, the odds of preferring RB as compared with MLB were significantly increased among persons with blue-collar occupations and those who reported drinking in public settings and were reduced among persons who drank outdoors, those who combined drinking with tobacco smoking, and those who drank alcohol with members of the same sex. Average daily ethanol consumption odds were reduced for RB drinkers as compared with MLB drinkers. The odds of preferring HL as compared with MLB were significantly increased for persons with white-collar occupations and those who drank in public settings and were reduced for persons who drank outdoors and those who combined drinking and smoking. CONCLUSION: The authors observed substantial differences in sociodemographic characteristics, drinking patterns, and ethanol consumption by beverage type in this community sample. MLB drinkers seem to have distinctive drinking patterns that require additional study to determine whether this pattern is associated with increased individual or community risk.
