ABSTRACT

OBJECTIVES: Human immunodeficiency virus (HIV) rates in the southeast United States are high and substance use is common among people living with HIV (PLWH). This study used baseline data from the weCare intervention study to examine factors associated with the use of alcohol, tobacco, and marijuana among racially and ethnically diverse young gay, bisexual, and other men who have sex with men (GBMSM) and transgender women in the southeast who were newly diagnosed as having HIV, not linked to care, out of care, and/or not virally suppressed. METHODS: Self-reported data were collected from 196 GBMSM and transgender women living with HIV via Audio Computer-Assisted Self-Interview at enrollment. Measures assessed demographics; stigma; social support; basic and clinical service needs; HIV disclosure; social media use; and recent use of alcohol, tobacco, and marijuana. Logistic regression identified correlates of past 30-day substance use. RESULTS: In multivariable analysis, increased age and needing basic support services were associated with past 30-day tobacco, cigarette, electronic cigarette, and/or hookah use. Increased HIV-related stigma and needing basic support services were associated with past 30-day marijuana use. Being White and needing clinical support services were associated with infrequent or no past 30-day marijuana use. CONCLUSIONS: HIV-related stigma and needing basic support services were associated with substance use among GBMSM and transgender women living with HIV in the southeastern United States. Routine screening for basic needs could identify GBMSM and transgender women living with HIV at risk for substance use and offer insight into intervention leverage points.

ABSTRACT

ABA is a phytohormone involved in diverse plant events such as seed germination and drought response. An F-box protein functions as a substrate receptor of the SCF complex and is responsible for ubiquitination of target proteins, triggering their subsequent degradation mediated by ubiquitin proteasome system. Here, we have isolated a gene named ARABIDOPSIS F-BOX PROTEIN HYPERSENSITIVE TO ABA 1 (AFA1) that was upregulated by ABA. AFA1 interacted with adaptor proteins of the SCF complex, implying its role as a substrate receptor of the complex. Its loss of function mutants, afa1 seedlings, exhibited ABA-hypersensitivity, including delayed germination in the presence of ABA. Moreover, loss of AFA1 led to increased drought tolerance in adult plants. Microarray data with ABA treatments indicated that 129 and 219 genes were upregulated or downregulated, respectively, by more than three times in afa1 relative to the wild type. Among the upregulated genes in afa1, the expression of 28.7% was induced by more than three times in the presence of ABA, while only 9.3% was repressed to the same extent. These data indicate that AFA1 is involved in the downregulation of many ABA-inducible genes, in accordance with the ABA-hypersensitive phenotype of afa1. Epistasis analysis showed that AFA1 could play a role upstream of ABI4 and ABI5 in the ABA signaling for germination inhibition. Collectively, our findings suggest that AFA1 is a novel F-box protein that negatively regulates ABA signaling.

ABSTRACT

BACKGROUND: Healthcare organizations are increasingly screening and addressing food insecurity (FI); yet, limited data exists from clinic-based settings on how FI rates change over time. The objective of this study was to evaluate household FI trends over a two-year period at a clinic that implemented a FI screening and referral program. METHODS: In this retrospective cohort study, data were extracted for all visits at one academic primary care clinic for all children aged 0-18 years whose parents/guardians had been screened for FI at least once between February 1, 2018 to February 28, 2019 (Year 1) and screened at least once between March 1, 2019 to February 28, 2020 (Year 2). Bivariate analyses tested for differences in FI and demographics using chi-square tests. Mixed effects logistic regression was used to assess change in FI between Years 1 and 2 with random intercept for participants controlling for covariates. The interaction between year and all covariates was evaluated to determine differences in FI change by demographics. RESULTS: Of 6182 patients seen in Year 1, 3691 (59.7%) were seen at least once in Year 2 and included in this study. In Year 1, 19.6% of participants reported household FI, compared to 14.1% in Year 2. Of those with FI in Year 1, 40% had FI in Year 2. Of those with food security in Year 1, 92.3% continued with food security in Year 2. Compared to Hispanic/Latinx participants, African American/Black (OR: 3.53, 95% CI: 2.33, 5.34; p < 0.001) and White (OR: 1.88, 95% CI: 1.06, 3.36; p = 0.03) participants had higher odds of reporting FI. African American/Black participants had the largest decrease in FI between Years 1 and 2 (- 7.9, 95% CI: - 11.7, - 4.1%; p < 0.0001). CONCLUSIONS: Because FI is transitional, particularly for racial/ethnic minorities, screening repeatedly can identify families situationally experiencing FI.

ABSTRACT

This chapter reviews the array of methods used in contemporary research on population-level research on substance use and its consequences. We argue that there are critical questions that can best - or in some cases, only - be addressed at the level of a population. We then describe the major categories of data collection methods used in population research, including surveys, ecological momentary assessment, administrative data, audit methods, and unobtrusive assessment of substance use. Two categories of measures are then discussed: measures of an individual's use of substances and related problems and measures of harm to others caused by one's use. We then review factors that may be considered causes or correlates of substance use and consequences, including both individual and environmental factors. We close with a few thoughts on the accumulation of knowledge and its translation to policy and practice.

ABSTRACT

The Latinx population in the United States is disproportionately affected by HIV. Our community-based participatory research partnership developed, implemented and evaluated a Spanish-language peer navigation intervention designed to increase HIV testing and condom use among social networks of immigrant Spanish-speaking Latinx gay, bisexual and other men who have sex with men (GBMSM) and transgender women (TW). We randomized 21 social networks of Latinx GBMSM and TW, ages 18-55 years, to the intervention, known as HOLA, or a waitlist control group. Social network participants (n = 166) completed structured assessments at baseline and 12-month follow-up (24 months after baseline). Follow-up retention was 95%. Individual in-depth interviews with a sample of participants documented their intervention-related experiences, needs, and priorities to inform future research. At follow-up, HOLA participants reported increased HIV testing (adjusted odds ratio = 8.3; 95% CI = 3.0-23.0; P < 0.0001). All study participants reported increased condom use; there was no significant difference between HOLA and waitlist control participants. In-depth interviews identified critical intervention elements and impacts and community needs and priorities. The HOLA intervention is effective for increasing HIV testing among Latinx GBMSM and TW, an initial step within the HIV prevention and care continua, and may be adaptable to promote pre-exposure prophylaxis uptake.

ABSTRACT

PURPOSE: We examined whether waterpipe café, vape shop, and traditional tobacco retailer (e.g. stores selling cigarettes, cigars, smokeless tobacco) locations were associated with census tract composition and tobacco use among young adults in North Carolina and Virginia. Methods: We identified waterpipe cafés, vape shops, and traditional tobacco retailers in North Carolina and Virginia and conducted multivariable analyses between community characteristics (gender, race, ethnicity, education, college enrollment, and poverty) and density per 1000 population. Using fall 2017 data from 1099 young adults residing in North Carolina and Virginia, we conducted logistic regression analyses to determine whether tobacco retailer density and proximity were associated with tobacco use. Results: Waterpipe café, vape shop, and traditional retailer density were higher in communities with more people who were Hispanic, college-educated, and college-enrolled (each p < .05). Waterpipe café and traditional retailer density were higher in communities with more people living below the poverty level (each p < .05). Waterpipe café density was higher in communities with more people who were male (p < .05), while traditional retailer density was lower (p < .05). Waterpipe café and vape shop proximity were associated with increased likelihood of waterpipe tobacco use in the past 6 months (each p < .05; unadjusted). Traditional retailer proximity and waterpipe café, vape shop, and traditional retailer density were not associated with tobacco use. Conclusions: Waterpipe cafés and vape shops are located in both impoverished and college-educated communities in North Carolina and Virginia, similar to where traditional tobacco retailers are located. Further research is needed to examine associations with tobacco use.

ABSTRACT

Young gay, bisexual, and other men who have sex with men and transgender women with HIV, particularly those who are racial or ethnic minorities, often have poor health outcomes. They also utilize a wide array of social media. Accordingly, we developed and implemented weCare, an mHealth (mobile health) intervention where cyberhealth educators utilize established social media platforms (e.g., Facebook, texting, and GPS-based mobile applications ["apps"]) designed for social and sexual networking) to improve HIV-related care engagement and health outcomes. As part of the process evaluation of weCare, we conducted 32 interviews with intervention participants (n = 18) and HIV clinic providers and staff (n = 14). This article highlights three key intervention characteristics that promoted care engagement, including that weCare is (1) targeted (e.g., using existing social media platforms, similarity between intervention participants and cyberhealth educator, and implementation within a supportive clinical environment), (2) tailored (e.g., bidirectional messaging and trusting relationship between participants and cyberhealth educators to direct interactions), and (3) personalized (e.g., addressing unique care needs through messaging content and flexibility in engagement with intervention). In addition, interviewees' recommendations for improving weCare focused on logistics, content, and the ways in which the intervention could be adapted to reach a larger audience. Quality improvement efforts to ensure that mHealth interventions are relevant for young gay, bisexual, and other men who have sex with men and transgender women are critical to ensure care engagement and support health outcomes.

ABSTRACT

BACKGROUND: Rates of high-intensity drinking, which is alcohol consumption that exceeds standard heavy drinking levels, have increased in recent years and peak in young adulthood. To identify modifiable environmental targets for prevention of high-intensity drinking, we identified characteristics of parties attended by youth and young adults that were associated with high-intensity drinking and the consequences of this excessive form of drinking. METHODS: Data are from 15- to 20-year-old participants in an online survey (n = 2,442; 55.4% female, 74.8% White) who resided in 24 communities across 7 states that were a part of a community randomized intervention trial to reduce the incidence and consequences of underage drinking parties. We used multinomial logistic regression to predict level of drinking by 6 party characteristics (size, location, age and gender composition, supervision, others' drinking behavior), and to predict 6 consequences (hangover, not remember event, passed out, punished by parents, broke something/got in fight, and sex against will) from level of drinking. We tested study hypotheses in 2 models, one that used a single binge drinking threshold (below binge vs. at or above binge level) and one that additionally used a high-intensity drinking level (below binge, 1 to 2 times binge, 2+ times binge level). RESULTS: We found that larger party size and a mostly male composition were unique predictors of high-intensity drinking when compared to those who consumed 1 to 2 times the binge drinking level. Odds of passing out, not remembering the drinking event, breaking/damaging property, or getting in a fight were more than double for high-intensity drinkers compared to standard binge level drinkers. CONCLUSIONS: Results from this study indicate there are unique precursors and consequences of high-intensity alcohol consumption among youth and young adults. These environmental factors associated with high-risk drinking contexts can be used to develop prevention strategies to mitigate the harms associated with excessive alcohol consumption.

ABSTRACT

Cognitive-psychosocial and other factors may affect participation in HIV testing, particularly by Hispanic/Latino gay, bisexual, and other men who have sex with men (MSM) in the U.S. South, a region hard-hit by HIV. We used univariate and multivariable logistic regression analyses to examine the association between social support and other cognitive-psychosocial factors; sociodemographic characteristics; risk behaviors; and self-reported HIV testing in a sample of 304 Hispanic/Latino MSM in North Carolina. In the multivariable logistic regression analysis, general and HIV-related social support and HIV-related knowledge were associated with greater odds of testing; speaking only Spanish was associated with reduced odds of testing. Social support and aspects of social connectedness may constitute community-based resources for use in HIV prevention efforts with Hispanic/Latino MSM. However, harnessing these resources for HIV prevention will require a better understanding of how social support relationships and processes shape HIV risks and protective actions by these vulnerable MSM.

ABSTRACT

BACKGROUND: Prior to the final deeming rule, federal law in the USA prohibited electronic cigarettes (e-cigarettes) from being marketed as smoking cessation products; for other therapeutic purposes and in ways that conveyed Food and Drug Administration (FDA) approval/endorsement. After August 2016, additional federal prohibitions were added including false/misleading and unauthorised modified risk tobacco product (MRTP) claims. No systematic investigation of e-cigarette health claims has been conducted in the retail environment. We sought to document and characterise claims made in vape shops. METHODS: Between November 2015 and February 2016, before final deeming rule implementation, two trained data collectors conducted unannounced observational assessments of 46 vape shops in North Carolina. Data collectors used wearable imaging technology to document health claims about e-cigarettes. Photos were coded for five claim types: (1) cessation device; (2) drug effect/device; (3) FDA-approved/endorsed; (4) false/misleading and (5) MRTP. Photos were double coded; differences between coders were adjudicated and reviewed by an expert panel. RESULTS: At least one health claim was displayed in 41.3% (n=19) of retailers, ranging from 0 to 27 claims per retailer. All claim types were found. Cessation device claims were the most prevalent (62.2%, n=84), followed by MRTP (27.4%, n=37), drug effect/device (8.1%, n=11), false/misleading (1.5%, n=2), and FDA approved/endorsed (0.7%, n=1). Retail chains made the majority of claims compared with independent shops (88.9% vs 11.1%). CONCLUSIONS: Many vape shops displayed e-cigarette health claims, which are all now FDA prohibited. These claims could mislead consumers and influence behaviour. Findings highlight the need for retailer education, continued surveillance, enforcement specific to advertising and research on consumer perceptions of claims.

ABSTRACT

Persons living with HIV (PLWH) have disproportionately high rates of both cigarette smoking and tobacco-induced negative health outcomes. The goal of this qualitative systematic review was to identify gaps in the existing literature and future directions for smoking cessation support for PLWH. Three online databases were searched from their inception through December 31, 2017, using designated search terms. Peer-reviewed English-language articles that documented an intervention designed to increase smoking cessation among PLWH were reviewed. Data were abstracted using a standardized form to document study and intervention characteristics and results. Thirty-two articles, describing 28 unique intervention studies, met inclusion criteria. Interventions consisted primarily of combinations of counseling, pharmacotherapy, and the use of information and communications technology; few interventions were implemented at the clinic level. Thirteen interventions resulted in significant improvements in cessation-related outcomes. Information and communications technology and clinic-level interventions had the greatest potential for increasing smoking cessation among PLWH. Efficacious interventions designed for PLWH in the US South, and for groups of PLWH facing additional health disparities (e.g., communities of color and sexual and gender minorities), are needed. There is also a need for more rigorous research designs to test the efficacy of interventions designed to increase cessation-related outcomes among PLWH.

ABSTRACT

Introduction: Electronic nicotine delivery systems (ENDS) are widely available and come in a variety of forms, including disposable cigalikes and refillable tank systems. However, little is known about their placement at the point-of-sale. We explored the placement of various ENDS types among tobacco retailers. Methods: Systematic assessments at the point-of-sale were completed by trained data collectors in 90 tobacco retailers, including grocery stores, convenience stores, and pharmacies in North Carolina, United States. Availability and placement of various ENDS types including cigalikes, e-hookahs, tank systems, and e-liquids was recorded. Results: Almost all retailers (97.8%) sold cigalikes; 41.4% sold devices labeled as e-hookahs; 54.4% sold tank systems; and 56.2% sold e-liquids. Fewer than half of stores placed ENDS exclusively behind the counter; significant differences in ENDS placement were found by store type. Grocery stores carried cigalikes, tank systems, and e-liquids and placed them exclusively behind the counter. Pharmacies only sold cigalikes; most placed them exclusively behind the counter (91.7%) with cessation aids and other tobacco products. Convenience stores carried all ENDS types and placed them with other tobacco products (55.1%) and candy (17.4%). Only about one-third of convenience stores placed ENDS exclusively behind the counter. Conclusions: This exploratory study shows ENDS availability and placement at the point-of-sale varies by retailer type. Pharmacies placed cigalikes with cessation aids behind the counter suggesting their ability to aid in smoking cessation. Most convenience stores placed ENDS in self-service locations, making them easily accessible to youth. Findings highlight the need for ENDS regulation at the point-of-sale. Implications: Our study highlights the need for regulatory efforts aimed at ENDS placement at the point-of-sale. While pharmacies and grocery stores offered fewer ENDS types and typically placed them in clerk-assisted locations, all ENDS types were found at convenience stores, some of which were placed in youth-friendly locations. Regulatory efforts to control ENDS placement and limit youth exposure should be examined, such as requiring products be placed in clerk-assisted locations and banning ENDS placement next to candy.

ABSTRACT

Members of the DDB1-CUL4-associated factors (DCAFs) family directly bind to DAMAGED DNA BINDING PROTEIN1 (DDB1) and function as the substrate receptors in CULLIN4-based E3 (CUL4) ubiquitin ligases, which regulate the selective ubiquitination of proteins. Here, we describe a DCAF protein, ABD1 (for ABA-hypersensitive DCAF1), that negatively regulates abscisic acid (ABA) signaling in Arabidopsis thaliana. ABD1 interacts with DDB1 in vitro and in vivo, indicating that it likely functions as a CUL4 E3 ligase substrate receptor. ABD1 expression is induced by ABA, and mutations in ABD1 result in ABA- and NaCl-hypersensitive phenotypes. Loss of ABD1 leads to hyperinduction of ABA-responsive genes and higher accumulation of the ABA-responsive transcription factor ABA INSENSITIVE5 (ABI5), hypersensitivity to ABA during seed germination and seedling growth, enhanced stomatal closure, reduced water loss, and, ultimately, increased drought tolerance. ABD1 directly interacts with ABI5 in yeast two-hybrid assays and associates with ABI5 in vivo by coimmunoprecipitation, and the interaction was found in the nucleus by bimolecular fluorescence complementation. Furthermore, loss of ABD1 results in a retardation of ABI5 degradation by the 26S proteasome. Taken together, these data suggest that the DCAF-CUL4 E3 ubiquitin ligase assembled with ABD1 is a negative regulator of ABA responses by directly binding to and affecting the stability of ABI5 in the nucleus.

ABSTRACT

OBJECTIVES: To evaluate the HOLA en Grupos intervention, a Spanish-language small-group behavioral HIV prevention intervention designed to increase condom use and HIV testing among Hispanic/Latino gay, bisexual, and other men who have sex with men. METHODS: In 2012 to 2015, we recruited and randomized 304 Hispanic/Latino men who have sex with men, aged 18 to 55 years in North Carolina, to the 4-session HOLA en Grupos intervention or an attention-equivalent general health education comparison intervention. Participants completed structured assessments at baseline and 6-month follow-up. Follow-up retention was 100%. RESULTS: At follow-up, relative to comparison participants, HOLA en Grupos participants reported increased consistent condom use during the past 3 months (adjusted odds ratio [AOR] = 4.1; 95% confidence interval [CI] = 2.2, 7.9; P < .001) and HIV testing during the past 6 months (AOR = 13.8; 95% CI = 7.6, 25.3; P < .001). HOLA en Grupos participants also reported increased knowledge of HIV (P < .001) and sexually transmitted infections (P < .001); condom use skills (P < .001), self-efficacy (P < .001), expectancies (P < .001), and intentions (P < .001); sexual communication skills (P < .01); and decreased fatalism (P < .001). CONCLUSIONS: The HOLA en Grupos intervention is efficacious for reducing HIV risk behaviors among Hispanic/Latino men who have sex with men.

ABSTRACT

BACKGROUND: The performance of a new intermediate-resolution method using a PCR-Luminex platform and LABType® SSO A, B DRB1 kits as an HLA typing method for the cord blood (CB) registry of the Korean population was investigated. METHODS: A total of 1,413 cord blood units (CBUs) were enrolled - 1,382 from Koreans and 31 from non-Koreans or mixed-ancestry individuals. HLA-A, -B, and -DRB1 typing was performed using the LABType® SSO typing kits. HLA typing with the DNA method and 2-digit results are mandatory for the public CB bank in Korea according to the "CB Act." RESULTS: The proportions of ambiguous results in the 2-digit assignment were 14.6% (206/1,413) and 14.8% (205/ 1,382) among the total subjects and the Korean donors, respectively. In the 2-digit resolution, 3 different HLA-A types (69 CBUs), 31 HLA-B types (124 CBUs), and 3 HLA-DRB1 types (13 CBUs) showed ambiguous results. The 'most probable type' to the ambiguous results based on the reported Korean HLA allele frequencies were able to be assigned. The most probable results were 100% consistent with the confirmed types as determined by the HD kits (DRB1) and additional PCR-SBT or PCR-SSP tests (A and B). Luminex technology is more automated and less labor intensive than the conventional SSO typing method, and the results are less affected by differences between inspectors. CONCLUSIONS: Although it is not satisfactory as a sole confirmation test and cannot be used as a replacement for the PCR-SBT test, the combination of Luminex technology with LABType® SSO kits and population frequency data provides a proper typing platform that can be used as a qualifying test for CB registries.

ABSTRACT

OBJECTIVES: We sought to understand how local immigration enforcement policies affect the utilization of health services among immigrant Hispanics/Latinos in North Carolina. METHODS: In 2012, we analyzed vital records data to determine whether local implementation of section 287(g) of the Immigration and Nationality Act and the Secure Communities program, which authorizes local law enforcement agencies to enforce federal immigration laws, affected the prenatal care utilization of Hispanics/Latinas. We also conducted 6 focus groups and 17 interviews with Hispanic/Latino persons across North Carolina to explore the impact of immigration policies on their utilization of health services. RESULTS: We found no significant differences in utilization of prenatal care before and after implementation of section 287(g), but we did find that, in individual-level analysis, Hispanic/Latina mothers sought prenatal care later and had inadequate care when compared with non-Hispanic/Latina mothers. Participants reported profound mistrust of health services, avoiding health services, and sacrificing their health and the health of their family members. CONCLUSIONS: Fear of immigration enforcement policies is generalized across counties. Interventions are needed to increase immigrant Hispanics/Latinos' understanding of their rights and eligibility to utilize health services. Policy-level initiatives are also needed (e.g., driver's licenses) to help undocumented persons access and utilize these services.

ABSTRACT

INTRODUCTION: E-cigarettes are relatively new products that simulate the smoking experience. This descriptive study assessed changes in e-cigarette availability and promotions among retailers in 11 college communities in North Carolina and Virginia during a 1-year period. METHODS: During the spring of 2012 and 2013, observers completed assessments in 320 tobacco-selling retailers, including grocery and convenience stores, pharmacies, and tobacco shops. Assessors collected e-cigarette availability, advertising, price, and promotions. RESULTS: E-cigarette availability increased among retailers from 24.7% in 2012 to 59.9% in 2013. They were available in the form of disposables and reusable kits and were most frequently available in tobacco shops, convenience stores, and pharmacies. The average price for disposables was $9.70 (SD = 1.07) in 2012 and $9.61 (SD = 2.10) in 2013; the average price for kits was $39.58 (SD = 15.79) in 2012 and $32.59 (SD = 18.65) in 2013. The presence of interior advertising increased from 12.7% to 50.6% (p < .0001), and the presence of exterior advertising increased from 7.6% to 22.8% (p = .0002). Convenience stores with gas (16.4%-70.4%; p < .0001) and without gas (6.0%-48.4%; p < .0001) had significant increases in the presence of interior advertising. Convenience stores with gas also had a significant increase in the presence of exterior advertising (8.2%-33.3%; p < .0001). Only 3% of retailers offered price promotions. CONCLUSIONS: Availability of e-cigarettes, including rechargeable kits and disposables, more than doubled during the study. The presence of interior and exterior advertising also significantly increased. Results underscore the need for further surveillance to understand how these environmental characteristics impact individual exposure and use of e-cigarettes.

ABSTRACT

OBJECTIVE: Smokeless tobacco (SLT) use is associated with specific adverse health effects. Knowledge of student tobacco use, including SLT, may guide inquiry into other risky health behaviors, and provide opportunities for health education of students. DESIGN: An incentivized email invitation to complete a web-based survey was sent to students at 11 colleges and universities in North Carolina and Virginia. METHODS: In autumn 2010, emails were sent to all first-year students (n=29,536) at 11 colleges and universities in North Carolina and Virginia, inviting them to participate in a brief web-based survey to be used to establish a cohort for the parent study evaluating tobacco use over 4 years. Survey items elicited demographic characteristics, tobacco use and other health behaviors. RESULTS: A total of 10,520 (36%) students responded. Past 30 day smoking and SLT use were 12% and 3%, respectively. Logistic regression analysis revealed that male gender (Adjusted Odds Ratio [AOR] = 11.6, 95% Confidence Interval [CI] = 8.16-16.59); current smoking (AOR = 5.5, 95% CI = 4.21-7.10), ever use of alcoholic energy drinks (AOR = 4.8, 95% CI = 3.63-6.43), and ≥ 5 days vs. < 3 days of physical activity a week (AOR = 1.5, 95% CI = 1.07-2.01) predicted risk of past 30 day SLT use. CONCLUSION: While SLT use is relatively uncommon, knowledge of significant correlations between student tobacco use, including SLT and other risky health behaviors, might guide clinicians' inquiry and provide opportunities for health education of students.

ABSTRACT

An adolescent's perception of norms is related to her or his engagement in alcohol-related behaviors. Norms have different sources, such as parents, peers, and community. We explored how norms from different sources were simultaneously related to different alcohol-related behaviors (current drinking, drunkenness, heavy episodic drinking, driving under the influence or riding with a impaired driver, and alcohol-related nonviolent consequences) using data collected in 2004 from 6,958 adolescents from 68 communities in five states. Results revealed that parent, friend, and community norms were related to adolescents' alcohol-related behavior, but the strength of these impacts varied across behaviors. The pattern of results varied when the analysis relied on all adolescents or just those who had consumed alcohol in the last year.

ABSTRACT

BACKGROUND: Free medical clinics serve a critical role in health care delivery of America's uninsured population, who are less likely to receive tobacco cessation counseling and 1½ times more likely than the general population to use tobacco. The authors evaluate the opportunities for and challenges to implementing the U.S. Public Health Service Guidelines for tobacco cessation in free clinics. METHODS: Six free clinics participated in this pilot study. Five objectives were targeted: implementation of a tobacco user identification system, education of all clinic staff and volunteers, dedication of a program champion, use of evidence-based treatment, and creation of a supportive environment that reinforces provider behavior. Key informant interviews and focus group data were used to describe the opportunities and barriers of implementing the Public Health Service Guidelines. RESULTS: All clinics adopted a user identification system, dedicated a program champion, adopted evidence-based counseling, and created an environment conducive for cessation. Common challenges included getting volunteers to attend on-site training programs, accessing nicotine replacement therapy, and promoting Quit Line usage, all of which are part of evidence-based treatment. CONCLUSION: With more than 1,200 free clinics nationwide, it is very important to understand the opportunities and barriers of implementing tobacco cessation services and systems in free clinics.
