RESUMO
PURPOSE: To determine whether there are rural/urban differences in e-cigarette use and reasons for use that vary across the 10 Health & Human Services (HHS) regions. METHODS: Age-adjusted bivariate and multivariable analyses were conducted for n = 225,413 respondents to the 2014-2015 Tobacco Use Supplement-Current Population Survey to estimate the prevalence of e-cigarette use. Reasons for e-cigarette use were collected from n = 16,023 self-respondents who reported ever using e-cigarettes. FINDINGS: While nationally rural residents appeared more likely to use e-cigarettes, adjusted results indicated that current e-cigarette use was significantly less likely across the northern and western regions (New England, East North Central, Heartland, North Central Mountain, Northwest, and Southwest Pacific regions). Reasons for e-cigarette use differed by urban/rural status and region; for example, the rationale to use e-cigarettes as a smoking cessation aid was significantly more common among rural compared to urban adults in the New England and New York/New Jersey regions, but less common in the Southeast. CONCLUSIONS: For several regions, there were no significant rural/urban differences in e-cigarette use and reasons for use. Yet those regions that present differences face the need to develop public health approaches to minimize urban/rural disparities in health education, services, and outcomes related to tobacco use, particularly where access to health care is limited. Public health campaigns and guidance for clinical care within HHS regions should be tailored to reflect regional differences in beliefs about e-cigarettes.

Rural areas of the United States have a higher smoking prevalence than urban areas. However, no recent studies have rigorously examined potential changes in this disparity over time or whether the disparity can be explained by demographic or psychosocial characteristics associated with smoking. The present study used yearly cross sectional data from the National Survey on Drug Use and Health from 2007 through 2014 to examine cigarette smoking trends in rural versus urban areas of the United States. The analytic sample included 303,311 respondents. Two regression models were built to examine (a) unadjusted rural and urban trends in prevalence of current smoking and (b) whether differences remained after adjusting for demographic and psychosocial characteristics. Results of the unadjusted model showed disparate and diverging cigarette use trends during the 8-year time period. The adjusted model also showed diverging trends, initially with no or small differences that became more pronounced across the 8-year period. We conclude that differences reported in earlier studies may be explained by differences in rural versus urban demographic and psychosocial risk factors, while more recent and growing disparities appear to be related to other factors. These emergent differences may be attributable to policy-level tobacco control and regulatory factors that disproportionately benefit urban areas such as enforcement of regulations around the sale and marketing of tobacco products and treatment availability. Strong federal policies and targeted or tailored interventions may be important to expanding tobacco control and regulatory benefits to vulnerable populations including rural Americans.

As future physicians capable of controlling tobacco dependence in the population, medical students are considered a main target for tobacco control interventions. This cross-sectional study reported on the prevalence of tobacco use (cigarettes and waterpipes) and associated knowledge and behaviour among 6th-year medical students in 2009-2010 from 6 medical schools in Lebanon. The self-administered questionnaire based on the Global Health Professional Survey (GHPSS) core questions also enquired about training in tobacco cessation approaches. All enrolled students were asked to participate; the response rate was 191/354 (54.3%). The prevalence of tobacco use was 26.3% for cigarettes and 29.5% for waterpipes. Smoking waterpipes was the only significant predictor for cigarette smoking and there was no difference by sex and socioeconomic status. A minority reported ever receiving any formal training in treatment approaches for tobacco dependence. Medical schools should include tobacco dependence treatment training programmes in their curriculum and discourage tobacco use.

Lay health advisers (LHAs) are increasingly used to deliver tobacco dependence treatment, especially with low-socioeconomic status (SES) populations. More information is needed about treatment adherence to help interpret mixed evidence of LHA intervention effectiveness. This study examined adherence to behavioral counseling and nicotine patches in an LHA intervention with 147 Ohio Appalachian female daily smokers. Participants were randomly selected from clinics and randomized to the intervention condition of a randomized controlled trial. Overall, 75.5% of participants received all seven planned LHA visits, 29.3% used patches for >7 weeks and approximately half received high average ratings on participant responsiveness. Depressive symptoms and low nicotine dependence were associated with lower patch adherence while high poverty-to-income ratio was associated with high responsiveness. Compared with those with fewer visits, participants who received all visits were more likely to be abstinent (22.5 versus 2.8%, P=0.026) or have attempted quitting (85.0 versus 47.4%, P=0.009) at 3 months. High participant responsiveness was associated with 12-month abstinence. LHA interventions should focus on improving adherence to nicotine patches and managing depression because it is an independent risk factor for low adherence.

RESUMO
OBJECTIVE: To examine current tobacco policy in US prisons and explore changes in prison tobacco policies over time. DATA SOURCE: Telephone survey of the 52 US departments of correction. MAIN OUTCOME MEASURES: Current tobacco policy; distribution of free tobacco; availability of smoking cessation programming and cessation aids. PARTICIPANTS: Complete responses were received from 51 of 52 (98%) departments, while one provided partial information. RESULTS: The majority of correctional systems (60%) reported total tobacco bans on prison grounds, with most remaining facilities (27%) having an indoor ban on tobacco use. No prisons distributed free tobacco. No major violence was reported relating to the implementation of stricter tobacco policies; however many respondents noted that tobacco became a major contraband item following the implementation of a total ban. While most prison systems with an indoor tobacco ban (86%) reported having tobacco cessation programmes, few of those with total bans (39%) continued such programmes after the initial transition period. CONCLUSION: Total tobacco bans have often been accompanied by the termination of tobacco cessation programmes. Such actions undermine efforts to promote long-term cessation resulting in a missed public health opportunity.

OBJECTIVES: The objective of this paper is to report on data on the perceptions regarding smoking and environmental tobacco smoke as well as the health communication patterns of a representative sample of 715 adult Chinese families with children under age 18 who had not banned smoking in the home. METHODS: We selected a representative sample of Chinese American families residing in New York's five boroughs: Brooklyn, Bronx, Manhattan, Queens, and Staten Island based on Chinese family surnames and interviewed them by telephone between December 2000-March 2001. All except 4% of the interviews were conducted in English; most respondents chose to speak Cantonese and lesser numbers chose Mandarin. FINDINGS: For the most part, respondents believed in the hazards of smoking, especially as it harms children living at home. To address smoking, respondents believed the physicians is the most trustworthy source of health information and the sources of health information consulted would be overwhelmingly the Chinese language newspaper, followed by Chinese language radio and television. CONCLUSIONS: This study represents the first systematic assessment of Chinese Americans in New York with regard to selected tobacco control issues. The findings provide the empirical base for developing potential messages using the source considered most trustworthy (the physician) and the vehicle most consulted (Chinese language media).

This study describes the survey results of a national random sample of members of the Oncology Nursing Society who reported the greatest number of barriers to delivering a tobacco cessation intervention with their patients. Nurses who perceived the greatest number of barriers were more likely to be current smokers and to be young and were less likely to have an advanced degree, to be a nurse practitioner, or to have administrative responsibilities. Those with greater barriers were less likely to deliver tobacco cessation interventions.

PURPOSE/OBJECTIVES: To describe oncology nurses' attitudes, smoking behaviors, and involvement in tobacco-control policy and legislation. DESIGN: Descriptive, cross-sectional survey. SAMPLE: Responses from 1,508 (38% return) of 4,000 randomly selected members of the Oncology Nursing Society (ONS). The typical respondent was female, age 44, a staff nurse, had practiced as an oncology nurse for 12 years, and was certified as an OCN. METHODS: A mailed survey with specific questions about smoking status and the importance of nursing involvement in healthcare policy and legislation for tobacco control. MAIN RESEARCH CONCEPTS: Attitudes about tobacco-control policies and legislation; sociodemographic, professional, and institutional variables; and tobacco use. FINDINGS: The majority (85%) of members stated that nursing involvement in tobacco-control healthcare policy and legislation was important. More than 90% of respondents supported prevention of youth access to tobacco and providing information about health effects of tobacco and cessation. Seven percent (n = 106) were current smokers. Significantly fewer smokers valued involvement in tobacco-control activities. Respondents with personal experience of tobacco-related illnesses were more likely to value involvement in advocacy activities. Educational programs to prevent tobacco use among youth and to help patients stop smoking received the most support (80%). IMPLICATIONS FOR NURSING PRACTICE: This sample of ONS members strongly supported involvement in tobacco-control policies and legislation. Smoking was associated with more negative attitudes about the importance of actively engaging in tobacco control. These oncology nurses recognized the need for additional educational programs to prevent tobacco initiation by youth.

The purpose of this pilot study was to examine the effectiveness of an 8-week, nurse-managed, peer-led smoking cessation intervention among HIV-positive smokers. The intervention was based on the Agency for Health Care Policy and Research Smoking Cessation Clinical Practice Guideline and was delivered by an ex-smoker who was HIV positive and had been trained by an advanced practice nurse to deliver cessation counseling. Eight male HIV-positive smokers were assigned to the intervention group and received (a) 21 mg nicotine patch therapy for 6 weeks, (b) weekly face-to-face or telephone counseling, and (c) skills training that included substitute strategies for dealing with not smoking. Those participants assigned to the control group received written self-help materials for smoking cessation. Abstinence rates at end of intervention and 8 months were compared between groups. At end of treatment, 62.5% of intervention group participants were biochemically confirmed as abstinent from smoking compared with 0% in the control group. Eight-month abstinence rates were 50% among the intervention group compared with 0% in the control group.

Understanding the contribution of race to factors associated with cigarette smoking and nicotine metabolism is essential for the characterization of patterns of tobacco use, nicotine dependence and incidence of tobacco-related diseases. This paper reports an investigation of cotinine levels among Southeast Asian smokers in two separate studies. Study 1 included 327 male and female smokers who participated in community-based interviews where smoking history information was obtained and a saliva continine sample was collected. Results indicated that subjects smoked an average of 11.2 cigarettes/day, with men reporting significantly higher consumption rates as compared to women (p < 0.0001). Subjects' mean cotinine level was 65 ng/ml with an average cotinine/cigarette ratio of 8.2. In Study 2, plasma and saliva cotinine in six Southeast Asian adult smokers were measured during 2 days of smoking followed by 6 days of abstinence. On day 1, mean plasma and saliva continine levels were 268 and 235 ng/ml, respectively. After 6 days of abstinence, mean levels had dropped to 12 ng/ml for plasma and 8 ng/ml in saliva. On average, it required at least 4.7 days for saliva continine levels to reach < 14 ng/ml. Mean cotinine concentrations during smoking differed in these two separate studies. Implications of these findings are discussed and future research recommendations are presented.

PURPOSE/OBJECTIVES: To determine the effectiveness of a nurse-managed smoking cessation intervention based on the Agency for Health Care Policy and Research's (AHCPR's) Smoking Cessation Guideline in a lung cancer surgery clinic. DESIGN: Quasi-experimental. SETTING: Urban, Midwest, academic, and tertiary care. SAMPLE: 25 adult male and female smokers with a confirmed diagnosis of lung cancer that had been surgically managed. Subjects were assigned to an intervention group (n = 14) or a usual-care group (n = 11). METHODS: Participants in the intervention group received a nurse-delivered, AHCPR-based smoking cessation intervention that included face-to-face and phone follow-up contact beginning with the first preoperative clinic consultation. Usual-care participants received routine care provided at the institution. MAIN RESEARCH VARIABLES: Self-reported smoking status with expired air carbon monoxide confirmation six months postsurgery. FINDINGS: Seventy-one percent of the intervention group was biochemically confirmed to be abstinent by expired air carbon monoxide, as compared to 55% in the usual-care group. CONCLUSIONS: Smokers diagnosed with lung cancer desired to quit smoking and may benefit from an intensive smoking cessation intervention at time of diagnosis. IMPLICATIONS FOR NURSING PRACTICE: Further research should include continuing evaluation of an intensive smoking cessation intervention with this population, and all clinicians should be trained to implement AHCPR's Smoking Cessation Guideline in practice.

Appalachians remain at high risk for cancer, heart and lung disease, in part because of their high prevalence of tobacco use; yet, information about their tobacco consumption patterns is limited. The purpose of this study was to describe tobacco consumption variables among rural adult Appalachian tobacco users. Subjects, aged 18 and older (N = 249), participated in a face-to-face interview about tobacco consumption variables and knowledge regarding the health effects of tobacco at fairs in two rural Ohio Appalachian counties. The majority of participants were categorized as precontemplators, although 21 percent were classified in preparation stage of change. Mean age of initiation was 16.6 years and number of cigarettes smoked per day (cpd) was significantly higher for men, as compared to women. One-third of males reported the use of smokeless tobacco. The majority had not tried to quit for more than a year and the average number of previous quit attempts was low. One-half of the sample had been advised in the past to quit by their physician. Few had used nicotine replacement with past quit attempts but greater than half would consider this approach with future attempts. Knowledge about the health effects of smoking indicated that most were aware of the relationship between smoking and cancer but less than one-half recognized its association with heart disease. Those with less education were less informed about the health effects to self and non-smokers. While a sizeable portion expressed interest in quitting, knowledge about the health effects of smoking is lacking, especially with regard to heart disease and among those with less education.

A 2-way factorial repeated measures design examined the effects of menstrual cycle phase and smoking on: 1) smoking behavior, 2) mood state, 3) nicotine withdrawal symptomatology, and 4) menstrual symptomatology. Female smokers, aged 20-39, were followed for two consecutive menstrual cycles with two data collection sessions per cycle, which were conducted in the University's General Clinical Research Center (GCRC). Participants were randomly assigned to order of smoking condition, which included: 1) smoking ad libitum, and 2) 24-hour abstinence prior to data collection. Data were collected in the mid-to-late follicular (MLF) phase (between days 6 through to 11) and the four days prior to menses in late luteal (LL) phase. Participants completed the Profile of Mood States and Menstrual Symptom Severity List and recorded daily cigarette smoking rate in the natural environment during MLF and LL phases. Nicotine boost and carbon monoxide (CO) boost were measured and the Shiffman-Jarvick Tobacco Withdrawal Questionnaire was administered during GCRC data collection sessions. Results indicated that subjects smoked more cigarettes per day during the LL phase and CO boost was greater during MLF. No difference was noted in nicotine boost by condition or phase. No difference in mood state was noted by either condition or phase. Withdrawal symptomatology and craving for cigarettes were increased after 24 hours of abstinence. No difference was noted in menstrual symptoms by condition or phase. Further investigations are still needed to characterize the importance of cycle phase in the design of smoking cessation interventions for women of reproductive age.

BACKGROUND: Tobacco use is an important risk factor in cancer, cancer recurrence, and increased treatment morbidity, but limited information is available about interventions for tobacco cessation used in oncology clinical practice. In 1996, the Agency for Health Care Policy Research (AHCPR) published the first evidence-based smoking cessation guideline for use by health professionals. Using the AHCPR guideline as a framework, the authors describe the frequency of tobacco interventions provided by oncology nurses. METHODS: A questionnaire was mailed to 4000 randomly selected members of the Oncology Nursing Society in winter of 1998. Of those who were mailed questionnaires, 1508 respondents (38%) were available for analysis. RESULTS: The typical respondent was female, 44 years of age, and had practiced as an oncology nurse for 12 years. Seven percent were current smokers, and 30% were former smokers. Most (86%) encountered smokers on a weekly basis, but only 10% had heard of the AHCPR guideline. The majority (64%) assessed and documented tobacco status, 38% assessed readiness to quit. Few went on to provide interventions: 36% provided counseling, 32% provided cessation advice, 24% recommended nicotine replacement, and 16% taught skills to prevent relapse. Common barriers included perceived lack of patient motivation (74%) and the nurse's lack of time (52%) and skills (53%). The majority stated that they wanted to help patients stop smoking (88%) but needed additional training (92%). CONCLUSIONS: Documentation of tobacco status alone is not adequate in assisting patients with smoking cessation. Greater efforts are needed to educate oncology nurses about the range of tobacco interventions available and to facilitate their use in clinical settings.

The effect of chronic nicotine administration on (1) antinociception; (2) opioid receptor binding; and (3) met-enkelphalin levels in discrete brain regions in rats was investigated. Male and female Sprague-Dawley rats were treated with nicotine 0.3 mg/kg, 0.1 mg/kg, or saline three times a day subcutaneously during a 14-day protocol. Antinociception was measured by hotplate (HP) test on days 1, 2, 7, 10 and 14. After completion of the protocol, mu-opioid receptors were analyzed by [3H]-DAMGO binding studies and met-enkelphalin levels were determined by radioimmunoassay. Results indicated that hot-plate latency increased during the first 2 days of nicotine administration for male and female rats who were treated with 0.3 mg/kg nicotine. There was an up-regulation of mu-receptors (increased Bmax) in the striatum of rats treated with 0.3 mg/kg nicotine, compared to 0. 1 mg/kg nicotine and saline groups. An interaction effect of group by gender was noted. After 14 days of chronic nicotine administration, met-enkelphalin levels were significantly lower in striatum and midbrain of animals treated with 0.3 mg/kg nicotine, as compared to controls. These results suggest that chronic nicotine administration, in doses representative of human smoking, produces antinociception initially, and is accompanied by an upregulation of micro-opioid receptors in the striatum of rats. In addition, nicotine-induced tolerance to antinociception may be associated with a decrease in met-enkelphalin level over a period of time.

Endogenous opioid peptides have been implicated in the reinforcement of smoking and opioid antagonists have been examined to determine their role in smoking behavior. To date, the relationship between smoking behavior and chronic opiate antagonist administration during ad libitum smoking has not been investigated. The purpose of this study was to examine the relationships between naltrexone, an opiate antagonist administered orally, and smoking behavior and mood states during ad libitum smoking. A repeated measures experimental design was used. Normal adult male and female volunteers, admitted to the Clinical Research Center, were randomly assigned to naltrexone-treated (n = 22) or placebo-control (n = 21) groups in a double-blind manner. Day 1 was considered acclimation to the unit and day 2 was baseline, or pre-drug administration. On days 3, 4, and 5, subjects received 50 mg naltrexone or a placebo at 0700 and 1600 hours. Plasma nicotine and expired air carbon monoxide levels were measured daily at 1900 hours. Number of cigarettes smoked, mood states, withdrawal symptomatology and self-reported satisfaction with smoking were also quantified daily. Results indicated that plasma nicotine levels (P = 0.005), number of cigarettes smoked daily (P = 0.003) and self-reported satisfaction with smoking (P = 0.043) were significantly lower among those treated with naltrexone, compared to the placebo-control group. Expired air carbon monoxide levels did not differ between the two groups. In addition, mood states and withdrawal symptoms did not differ between groups. These findings suggest that endogenous opioid peptides influence specific smoking behavior variables.

Lung lymphocyte numbers are frequently increased in human immunodeficiency virus (HIV)-infected individuals in the absence of lung infection, and may play a critical role in viral surveillance and protection against new infections. In this context, cigarette smoking by HIV-infected individuals has been associated with a relative increase in the peripheral blood CD4(+) T-lymphocyte count as compared with that of nonsmokers. Because lung defense is local, the aim of the present study was to determine whether cigarette smoking had a significant impact on local lung defenses in HIV-infected individuals. The numbers and subtypes of bronchoalveolar lymphocytes and the ability of lung lavage cells to produce proinflammatory cytokines were compared in 58 smokers and 34 nonsmokers. In contrast to a trend toward an increase in peripheral blood CD4(+) cell counts among nonsmokers, smokers had significant depressions in both the percentage and absolute numbers of CD4(+) and CD8(+) cells in their bronchoalveolar lavage fluid (BALF). A decrease in CD4(+)/CD8(+) cell ratios was also seen with smoking. In addition, production of both interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) was suppressed with cigarette smoking. These observations show that cigarette smoking is associated with suppression in localized lung defenses, and suggest that smoking cessation may have a positive impact on lung defenses in HIV-infected smokers.

PURPOSE/OBJECTIVES: To determine the effectiveness of a nurse-managed minimal smoking-cessation intervention among hospitalized patients with cancer. DESIGN: Prospective, two-group, randomized clinical trial. SETTING: Urban, academic, tertiary-care setting. SAMPLE: 28 adult male and female smokers with a diagnosis of cancer who are hospitalized for a surgical procedure. METHODS: During hospitalization, subjects were assigned to a minimal smoking-cessation intervention group (n = 14) or a usual care group (n = 14). Verification of smoking status was performed at a clinic visit six weeks postintervention. Nonsmoking status was defined as self-report of zero cigarettes/day during the prior week and confirmed by saliva cotinine analysis. MAIN RESEARCH VARIABLES: One-time, Inpatient, nurse-managed, minimal smoking-cessation intervention, self-reported smoking status, and saliva cotinine level of < or = 14 ng/ml. FINDINGS: Upon hospital admission, 64% of the intervention group and 71% of the usual care group reported their intention to quit smoking. At six weeks postintervention, only 21% and 14% of the intervention and usual care group, respectively, were classified as abstinent from smoking. More than 90% of the intervention group members who resumed smoking did so within first week of discharge. IMPLICATIONS FOR NURSING PRACTICE: A more intensive intervention may be necessary to assist hospitalized surgical patients in achieving smoking cessation. Additional contact prior to discharge or within the first few days postdischarge may be necessary to reinforce strategies for remaining abstinent.

Smoking cessation treatment by nurses in clinical practice significantly increases the number of smokers who are able to successfully quit the behavior. Nurse-managed cessation interventions have been shown to be effective with smokers, yet many nurses lack the knowledge to identify smokers easily, to identify those treatments that are most efficacious, and to deliver appropriate interventions. This article highlights recent developments in smoking cessation treatment that can be integrated into nursing practice. Attention is given to cessation techniques in special populations, including youth.
