RESUMO

OBJECTIVE: To determine the relationship between past-year internalizing symptoms and the time to first report of signs of nicotine dependence among young people. METHODS: Secondary analysis using data from the Population Assessment of Tobacco and Health (PATH) (Waves 1-5; 2013-2019). The study included 2,102 (N = 5,031,691) young people (age 12-23 years) who reported past-30-day (P30D) e-cigarette use in one or more waves. Kaplan Meier curves, stratified by past year internalizing symptoms were used to estimate the time to the first report of three nicotine dependence symptoms (i.e., use within 30 min of waking, cravings, and really needing to use) following the first P30D e-cigarette use. Cox proportional hazard models were used to estimate crude and adjusted hazard ratios (AHR), comparing any past year internalizing symptoms to no past year internalizing symptoms. RESULTS: We found no significant differences between past year internalizing symptoms and the time to the first report of cravings (AHR = 1.30, 95 % CI = 92-1.85), really needing to use (AHR = 1.31; 95 % CI = 0.92-1.89) and use within 30 min of waking for follow-up times 0-156 weeks (AHR = 0.84; 95 % CI = 0.55-1.30) and > 156 weeks (AHR = 0.41; 95 % CI = 0.04-4.67) respectively. CONCLUSION: Past year internalizing symptoms did not modify the time to the first report of nicotine dependence among youth with P30D e-cigarette use. Further research is needed to understand how changing internalizing symptoms and e-cigarette use frequency influence nicotine dependence over time and, how this relationship impacts cessation behavior.

RESUMO

Background: Despite public knowledge of the adverse health effects of tobacco use, cigarettes remain widely used due to the addictive nature of nicotine. Physiologic adaptation to the presence of nicotine over time leads to unpleasant effects during withdrawal periods. Alongside these physiological effects, tobacco users often report changes in their consumption of tobacco in response to their emotional state. Objectives: We hypothesized that idiographic, or person-specific level, increases in participants' negative affect (NA) and positive affect (PA) ratings at a given time point would be associated with higher and lower craving and smoking over the following several hours, respectively. Fifty-two participants completed block randomized ecological momentary assessment surveys on their smartphones 4 times per day for 30 days, reporting from 0-100 their level of seven discrete emotions, stress, current craving, and smoking behavior. We analyzed the relationships between affect and smoking and craving using idiographic generalized linear models. Results: While some participants exhibited the hypothesized relationships, each participant varied in the strength and direction of the relationships between affect and craving/smoking. These outcomes were partially moderated at the group level by anxiety/depression at baseline, but not by level of nicotine dependence or sex. Conclusions: This suggests that the factors driving cigarette use vary significantly between individuals.

RESUMO

Burdens related to pain, smoking/nicotine dependence, and pain-smoking comorbidity disproportionately impact Black Americans, and menthol cigarette use is overrepresented among Black adults who smoke cigarettes. Menthol may increase nicotine exposure, potentially conferring enhanced acute analgesia and driving greater dependence. Therefore, the goal of the current study was to examine associations between pain, menthol cigarette use, and nicotine dependence. Data was drawn from Black adults who were current cigarette smokers (n = 1370) at Wave 5 (2018-2019) of the Population Assessment of Tobacco and Health Study. Nicotine dependence was assessed using the Wisconsin Inventory of Smoking Dependence Motives. ANCOVA revealed that moderate/severe pain (vs. no/low pain) was associated with greater overall nicotine dependence (p < .001) and greater negative reinforcement, cognitive enhancement, and affiliative attachment smoking motives (ps < .001). Menthol smokers with moderate/severe pain also endorsed greater cigarette craving and tolerance, compared to non-menthol smokers with no/low pain (ps < .05). Findings support the notion that among Black individuals who smoke cigarettes, the presence of moderate/severe pain (vs. no/low pain) and menthol use may engender greater physical indices of nicotine dependence relative to non-menthol use. Compared to no/low pain, moderate/severe pain was associated with greater emotional attachment to smoking and greater proclivity to smoke for reducing negative affect and enhancing cognitive function. Clinical implications include the need to address the role of pain and menthol cigarette use in the assessment and treatment of nicotine dependence, particularly among Black adults. These data may help to inform evolving tobacco control policies aimed at regulating or banning menthol tobacco additives.

RESUMO

INTRODUCTION: with regards to tobacco dependence management, there are certain barriers to successful smoking cessation for patients, such as untreated anxiety and depression. Complicating the impact of mental health morbidities on tobacco dependence may be the significant portion of patients whose mental health issues and limited social connections are undiagnosed and unaddressed. We hypothesize that patients with no prior mental health diagnoses who are treated for tobacco dependence have high rates of undiagnosed mental health morbidities. METHODS: patients were recruited from a tobacco treatment clinic in 2021. Every patient who came for an inaugural visit without a prior diagnosis of mental health disease was screened for depression, anxiety, social isolation and loneliness. Sociodemographic variables were collected. RESULTS: over a 12-month period, 114 patients were seen at the tobacco treatment clinic. Of these 114 patients, 77 (67.5%) did not have a prior diagnosis of a mental health disease. The mean age was 54.3 ± 11.2 years, 52 (67.5%) were females, and 64 (83.1%) were Black/African American. The mean age of starting smoking was 19.3 ± 5.2 years, and 43 (55.8%) had never attempted to quit smoking in the past. With regards to mental health screening, 32 (41.6%) patients had a score of 9 or greater on the Patient Health Questionnaire (PHQ) 9, 59 (76.6%) had a score of 7 or greater on the Generalized Anxiety Disorder (GAD) 7, 67 (87.0%) were identified with social isolation and 70 (90.1%) for loneliness on screening. CONCLUSION: there was a high prevalence of undiagnosed mental health morbidities and social disconnection in patients who were actively smoking and were struggling to achieve smoking cessation. While a larger scale study is necessary to reaffirm these results, screening for mental health morbidities and social disconnection may be warranted in order to provide effective tobacco dependence management.

RESUMO

INTRODUCTION: Cigarette demand, or relative value, can be assessed via analysis of performance on a hypothetical behavioral economic cigarette purchase task (CPT). Substance purchase tasks are highly amenable to manipulation, namely, external stimuli, instructional changes, or acute stressors. In this regard, the current secondary analysis evaluates the role a novel, computerized stress induction paradigm, the Contextual-Frustration Intolerance Typing Task (C-FiTT), plays in eliciting varying levels of stress and resulting demand. METHOD: Daily smokers (n = 484) completed the C-FiTT wherein they were randomly assigned to one of five distress conditions: combination of task difficulty (low or high difficulty) with neutral or withdrawal cues, and a neutral control group. Tobacco demand was assessed immediately following the distress task using the hypothetical CPT. RESULTS: The C-FiTT distress-induction task significantly increased key cigarette demand indices, including price at maximum expenditure (Pmax) and first price where consumption was suppressed to zero (breakpoint). Moreover, demand increased with severity of C-FiTT condition, with the high-difficulty condition resulting in significantly higher breakpoint and Pmax, compared to other conditions. C-FiTT condition was not related to a significant increase in Omax, intensity, or elasticity. DISCUSSION: The novel C-FiTT paradigm produced comparable effects on tobacco demand relative to in vivo withdrawal induction, indicating that the C-FiTT is a viable procedure by which to influence demand. Reduction of internal and external stressors may be effective in lowering motivation for tobacco. These results highlight the importance of state distress in tobacco demand, and offer a potential avenue for intervention.

RESUMO

INTRODUCTION: Behavioral economic demand provides a multidimensional understanding of reinforcement. Commodity purchase tasks are an efficient method for measuring demand in human participants. One challenge in translating these procedures to electronic nicotine delivery systems (ENDS or e-cigarettes) is defining commodity units given the lack of standardization in the e-cigarette marketplace. AIMS AND METHODS: The purpose of this study was to directly compare methods of operationalizinge-cigarette purchases, puffs, cartridges, and mLs liquid, using a within-subject design. Participants (N = 132) reporting past week e-cigarette use were recruited using crowdsourcing. Purchase tasks were completed operationalizing e-cigarette units as puffs or cartridges at baseline and puffs or mLs liquid at a 3-month follow-up. RESULTS: Bivariate associations supported convergent and discriminant validity with the largest effect size correlations for intensity and elasticity observed for the puff version. Interaction models suggested that product preferences moderated the relationship between time-to-first use and cartridge demand with larger effect size correlations among persons reporting a preference for JUULs, but weaker relationships among persons reporting other device preferences. Puff intensity (rxx = .61) and elasticity (rxx = .62) showed good test-retest reliability for participants reporting stable consumption, but poor test-retest reliability for individuals with changed consumption levels (intensity rxx = -.08; elasticity rxx = -.10). CONCLUSIONS: This study highlights the relevance of commodity definitions in the e-cigarette purchase task. Puffs as an experimental commodity may provide flexibility for studying e-cigarette demand in heterogenous or unknown populations, whereas more tailored or personalized approaches like cartridge or mL-based tasks will likely be helpful when studying known subgroups. IMPLICATIONS: The commodity purchase task procedure is widely used for understanding cigarette and e-cigarette demand in nicotine dependence research. This study evaluates the importance of operational definitions of e-cigarette commodities in the purchase task (ie, puffs, cartridges, or mLs liquid). Puffs may provide a more flexible commodity unit when evaluating e-cigarette demand in general or heterogenous populations, whereas device-specific units may prove more valuable when studying populations with consistent and known product use.

RESUMO

Abstract: Introduction: The current policy of interiorization of medical education worldwide and the application of active methods, as well as the lack of consensus regarding the factors associated with medical students' quality of life are topics of discussion in the medical literature. Objective: In view of the scarcity of analyses on the subject, this study aimed to evaluate the topictopic at a medical school in a Brazilian northeast countryside university. Method: Cross-sectional study, developed from March to May of 2018. The questionnaire WHOQOL-bref was used to evaluate the quality of life and the data were related to: sociodemographic characteristics, anthropometric data and lifestyle. Data analysis was performed using descriptive statistics; then, a bivariate analysis was performed with a test for comparison of mean scores aimed to identify possible variables associated with the investigated domains. Binary logistic regression was performed to identify possible factors associated with poor quality of life in the investigated domains. The statistical analysis estimated 95% CI and p-value <0.05. Results: The present study characterized the students' quality of life and identified the following factors as being associated with poor quality of life: female gender, attending preclinical years, being a smoker, having normal weight classified according to the body mass index, having a negative assessment of their own health and quality of life. The results also showed that most students had a negative evaluation regarding the physical, psychological and environmental domains; in contrast to the social relationships domain, in which most reported a positive assessment. Conclusion: The findings allow discussions about measures aimed at dealing with factors that affect the quality of life of medical students attending medical schools located in remote and rural regions.


Resumo: Introdução: A atual política de interiorização da educação médica mundial e a aplicação de métodos ativos, bem como a falta de consenso sobre os fatores associados à qualidade de vida dos estudantes de Medicina, são conhecidos temas de discussão na literatura médica. Objetivo: Tendo em vista a escassez de análise sobre o assunto, este estudo teve como objetivo avaliar a qualidade de vida entre os estudantes de Medicina de uma universidade do interior do Nordeste brasileiro. Método: Trata-se de um estudo transversal, desenvolvido de março a maio de 2018. Utilizou-se o questionário WHOQOL-bref para avaliar a qualidade de vida, e os dados foram relacionados a características sociodemográficas, dados antropométricos e estilo de vida. Analisaram-se os dados por meio de estatística descritiva, e, em seguida, fez-se a análise bivariada com teste para comparação das médias dos escores, a fim de identificar possíveis variáveis associadas aos domínios investigados. Realizou-se regressão logística binária para identificar possíveis fatores associados à pior qualidade de vida nos domínios investigados. A análise estatística estimou IC 95% e valor de p < 0,05. Resultado: O presente estudo caracterizou a qualidade de vida dos estudantes de Medicina e identificou como principais fatores associados à má qualidade de vida: ser do sexo feminino, cursar anos pré-clínicos, ser fumante, ter peso normal classificado pelo índice de massa corporal e apresentar uma avaliação negativa da própria saúde e da qualidade de vida. Os resultados também evidenciaram que a maioria dos estudantes apresentou uma avaliação negativa nos domínios físico, psicológico e meio ambiente, em contraste com o domínio relações sociais, ao qual a maioria atribuiu uma avaliação positiva. Conclusão: Os achados permitem discutir acerca de medidas voltadas a lidar com fatores que prejudicam a qualidade de vida de alunos de escolas de Medicina em regiões remotas e rurais.

RESUMO

BACKGROUND: Clinical guidelines on smoking cessation contain recommendations for various evidence-based methods. The goal of this study was to provide a represen- tative analysis for Germany of the percentage of smokers who try to quit smoking at least once per year, the use of evidence-based methods and other methods of smoking cessation, and potential associations of the use of such methods with the degree of tobacco dependence and with socioeconomic features. METHODS: Data from 19 waves of the German Smoking Behavior Questionnaire (Deutsche Befragung zum Rauchverhalten, DEBRA), from the time period June/July 2016 to June/July 2019, were analyzed. Current smokers and recent ex-smokers (<12 months without smoking) were asked about their smoking cessation attempts in the past year and the methods they used during the last attempt (naming more than one method was permitted). The degree of tobacco dependence in current smokers was assessed with the Heaviness of Smoking Index. RESULTS: Out of 11 109 current smokers and 407 recent ex-smokers, 19.9% (95% confidence interval: [19.1; 20.6]) had tried to quit smoking at least once in the preceding year. 13.0% of them [11.6; 14.5] had used at least one evidence-based method during their last attempt. The stronger the tobacco dependence, the more likely the use of an evidence-based method (odds ratio [OR] = 1.27 [1.16; 1.40]). Pharmacotherapy (nicotine replacement therapy, medication) was used more com- monly by persons with higher incomes (OR = 1.44 per 1000 euro/month [1.28; 1.62]). Electronic cigarettes were the most commonly used single type of smoking cessation support (10.2 % [9.0; 11.6]). CONCLUSION: In Germany, only one in five smokers tries to quit smoking at least once per year. Such attempts are only rarely supported by evidence-based methods and are thus likely to fail. The high cost of treatment must be borne by the individual and thus fall disproportionately on poorer smokers. It follows that there is an urgent need for vered by health insurance pro- viders, in order to give all smokers fair and equal access to the medical care they need.

RESUMO

AIMS: The cooling and minty flavor of menthol in cigarettes has been hypothesized to mask the harshness of inhaled cigarette smoke, contributing to menthol's appeal and subjective reinforcement and linking menthol use to smoking initiation, progression, nicotine dependence, and difficulty quitting. This study examined differences between menthol and non-menthol smokers on behavioral economic indices of reinforcing efficacy (i.e., demand) and subjective response to smoking (i.e., satisfaction, reward, "throat hit," aversion) and the association between measurements of reinforcement and subjective response. DESIGN: 600 current adult smokers were recruited from an online smoking cessation program. Following website enrollment, individuals completed a self-report measurement of subjective response to smoking (reward, satisfaction, aversion, "throat hit"), and a modified cigarette purchase task (CPT) to assess behavioral economic cigarette demand. FINDINGS: In bivariate and adjusted ANOVA models, menthol smokers reported greater subjective reward, satisfaction, and positive sensations in the throat ("throat hit") from smoking compared to non-menthol smokers; and those outcomes were also correlated with greater nicotine dependence and lower likelihood of a past-year quit attempt. Although cigarette demand was associated with smoking level, subjective smoking reward, and nicotine dependence, there were no differences in smoking demand between menthol vs. non-menthol smokers. CONCLUSIONS: The pleasurable aspects of menthol vs non-menthol smoking may be a mechanism linking it to greater nicotine dependence and difficulty quitting. A menthol ban could decrease population-level cigarette consumption by restricting smokers' access to a highly rewarding cigarette flavoring.

RESUMO

BACKGROUND: Menthol cigarettes appeal to adolescents because they mask the harsh taste and sensation of tobacco smoke thereby making it easier to inhale the smoke. As a result, menthol cigarette users expose themselves to higher levels of nicotine relative to non-menthol cigarettes and increase their risk for developing nicotine dependence. We examined whether adolescent menthol smokers (vs. non-menthol smokers) reported higher nicotine dependence. METHODS: Data were from adolescent past 30-day cigarette smokers participating in Wave 2 of the Population Assessment of Tobacco and Health survey (n = 434). Nicotine dependence was assessed using eight items from the Wisconsin Inventory of Smoking Dependence Motives corresponding to individual subscale constructs. Linear regression models evaluated the association of past 30-day menthol (vs. non-menthol) cigarette use with each dependence outcome in separate models, adjusting for age, gender, race, and other tobacco product use. RESULTS: 49.5% of past 30-day youth cigarette smokers reported smoking menthol cigarettes. In adjusted models, menthol smokers (vs. non-menthol smokers) reported significantly higher nicotine dependence for three constructs: craving (p = 0.005), affiliative attachment (p = 0.005), and tolerance (p = 0.003). No differences for menthol vs. non-menthol smokers were observed for loss of control, negative reinforcement, cognitive enhancement, automaticity, or social environment after correction for multiple comparisons. CONCLUSIONS: Findings suggest that menthol cigarette smokers are not just more physically dependent on nicotine but also experience increased emotional attachments to cigarettes compared to their non-menthol smoking peers. Because adolescents are vulnerable to developing nicotine dependence, tobacco control policies that restrict youth access to menthol cigarettes are urgently needed.

RESUMO

Little is known about the neural functioning that underpins drug valuation and choice in addiction, including nicotine dependence. Following ad libitum smoking, 19 dependent smokers (smoked≥10/day) and 19 occasional smokers (smoked 0.5-5/week) completed a decision-making task. First, participants stated how much they were willing-to-pay for various amounts of cigarettes and shop vouchers. Second, during functional magnetic resonance imaging, participants decided if they wanted to buy these cigarettes and vouchers for a set amount of money. We examined decision-making behaviour and brain activity when faced with cigarette and voucher decisions, purchasing (vs not purchasing) cigarettes and vouchers, and "value signals" where brain activity correlated with cigarette and voucher value. Dependent smokers had a higher willingness-to-pay for cigarettes and greater activity in the bilateral middle temporal gyrus when faced with cigarette decisions than occasional smokers. Across both groups, the decision to buy cigarettes was associated with activity in the left paracingulate gyrus, right nucleus accumbens, and left amygdala. The decision to buy vouchers was associated with activity in the left superior frontal gyrus, but dependent smokers showed weaker activity in the left posterior cingulate gyrus than occasional smokers. Across both groups, cigarette value signals were observed in the left striatum and ventromedial prefrontal cortex. To summarise, nicotine dependence was associated with greater behavioural valuation of cigarettes and brain activity during cigarette decisions. When purchasing cigarettes and vouchers, reward and decision-related brain regions were activated in both groups. For the first time, we identified value signals for cigarettes in the brain.

RESUMO

INTRODUCTION: The Reinforcer Pathology Model describes how two behavioral economic processes, increased sensitivity to immediate rewards (delay discounting) and excessive reward derived from a substance (demand), both contribute to problematic patterns of substance use. In a novel application of this model, the current cross-sectional study examined how these distinct processes relate to different facets of cigarette use in adolescents. METHODS: Adolescent daily cigarette smokers ages 15 to 19 (Mean age 17.7, N = 50) completed a laboratory assessment of demand using a Cigarette Purchase Task for their usual brand cigarettes and an adjusting-amount delay discounting task. Demand was conceptualized as two factors (Amplitude and Persistence) and delay discounting was calculated as Area Under the Curve (log AUC). The two factors of demand and discounting AUC were included as statistical predictors of level of cigarette dependence and average number of cigarettes smoked per day in linear regression models. RESULTS: Amplitude of demand was marginally significant predictor (p = .06) of cigarettes smoked per day whereas neither Persistence of demand nor delay discounting significantly predicted this outcome. Both Amplitude of demand and delay discounting, but not Persistence, were associated with level of cigarette dependence. The effects of amplitude of demand and delay discounting on cigarette dependence or use did not significantly interact. CONCLUSIONS: Results of this study suggest that amplitude of cigarette demand may be a risk factor for both cigarette consumption and dependence, while discounting - a known risk factor for cigarette initiation - may relate specifically to level of dependence.

RESUMO

INTRODUCTION: Unemployment has been related to smoking, yet the causal nature of the association is subject to continued debate. Social causation argues that unemployment triggers changes in smoking, whereas the social selection hypothesis proposes that pre-existing smoking behavior lowers the probability of maintaining employment. The present study tested these competing explanations while accounting for another alternative explanation-common liability. METHODS: Data were from the Christchurch Health and Development Study, a longitudinal cohort followed from birth to age 35. Odds were generated for having nicotine dependence in models for social causation and being unemployed in models for social selection. These models were extended to include possible common liability factors during childhood (eg, novelty seeking) and young adulthood (eg, major depression). RESULTS: In the model testing social causation, coefficients representing the impacts of unemployment on nicotine dependence remained statistically significant and robust (odds ratio [OR] = 1.55; 95% confidence interval [CI] = 1.20, 2.00), even after accounting for common determinant measures. In contrast, a reverse social selection model revealed that coefficients representing the impacts of nicotine dependence on unemployment substantially attenuated and became statistically nonsignificant as childhood factors were added (OR = 1.14; 95% CI = 0.90, 1.45). CONCLUSIONS: Unemployment may serve as inroads to nicotine addiction among young adults, not the other way, even in the context of nicotine dependence, a more impaired form of smoking that may arguably hold higher potential to generate social selection processes. This social causation process cannot be completely attributable to common determinant factors. IMPLICATIONS: It is critical to clarify whether unemployment triggers changes in smoking behaviors (ie, social causation) or vice versa (ie, social selection)-the answers to the question will lead to public health strategies with very different intervention targets to break the linkage. The current study findings favor social causation over social selection, regardless of gender, and support a needed shift in service profiles for unemployed young adults-from a narrow focus on job skills training to a more holistic approach that incorporates knowledge from addiction science in which unemployed young adults can find needed services to cope with job loss.

RESUMO

Introducción. El trabajo ocupa un lugar clave en la vida de la mujer, y a su vez comprende varias dimensiones. Dos de ellas son el trabajo doméstico no remunerado (TDNR) e invisibilizado, y el trabajo productivo remunerado (TPR) fuera dela casa. El objetivo de esta investigación fue comprender cómo es la percepción de salud en la mujer actual de clase media urbana con doble jornada laboral y cómo ella jerarquiza su TPR. Métodos. Investigación con enfoque cualitativo realizada en un hospital privado universitario de la Ciudad de Buenos Aires, mediante entrevistas individuales a mujeres adultas y alfabetas de 30 a 60 años de edad, seleccionadas a través del método de bola de nieve a partir de sus médicos de cabecera. Se utilizaron fichas demográficas estructuradas y entrevistas en profundidad. Se registraron datos personales y prácticas médicas realizadas en los últimos años. Se realizó un análisis de contenido. Resultados. Entrevistamos a 47 mujeres, la mayoría con hijos y la mitad, a cargo de las tareas domésticas en su hogar. Ninguna de ellas reconoció la tarea doméstica (TDNR) como trabajo, 76 % refirió no realizar controles habituales de salud,aunque más del 90 % hizo las prácticas preventivas recomendadas para su edad. Las mujeres entrevistadas expresaron diferentes significados atribuidos por ellas al TPR como independencia, desarrollo personal, mejoría en autoestima, calidad de vida, y sociabilidad. Sin embargo, ante su ausencia en el hogar se mostraron ambivalentes y con sentimientos de culpabilidad. Conclusiones. Este estudio permite reconocer que las mujeres con trabajo TDNR y TPR valoran positivamente a este último, pero se cuestionan que éste les quite tiempo a su participación en el ámbito familiar. Esto resulta en una mayor autoexigencia y perpetúa la invisibilidad del TDNR. En relación al autocuidado, sienten que no realizan sus cuidados médicos, pero tienen buenos indicadores de prácticas preventivas. Quizás sea necesario propiciar la reflexión acerca del rol que tiene el TPR en su bienestar. (AU)


Introduction. Work occupies a key place in the life of women, and in turn, comprises several dimensions. Two of them are unpaid domestic work (UDW) and paid productive work (PPW) outside the home. The objective of this research was to understand how the perception of health is in the current urban middle-class woman with a double working day and how she prioritizes her PPW. Methods. Research with a qualitative approach carried out in a private university hospital in the City of Buenos Aires, through individual interviews with adult and literates women aged 30 to 60, selected through the snowball method from their general practitioners. Structured demographics and in-depth interviews were used. Personal data and medical practices carried out in recent years were recorded. A content analysis was performed. Results. We interviewed 47 women, the majority with children and half of them, in charge of housework in their home. None of them recognized housework (UDW) as work, 76 % reported not doing regular health checks, although more than 90 % did the recommended preventive practices for their age. The women interviewed expressed different meanings attributed bythem to the PPW such as independence, personal development, improvement in self-esteem, quality of life, and sociability. However, in their absence at home, they were ambivalent and guilty. Conclusions. This study allows us to recognize that women with UDW and PPW value the latter positively, but question whether it takes time away from their participation in the family environment. This results in increased self-demand and perpetuates the invisibility of the UDW. In relation to self-care, they feel that they do not perform their medical care, buthave good indicators of preventive practices. It may be necessary to encourage reflection on the role of the PPW in theirwell-being. (AU)

RESUMO

BACKGROUND AND AIMS: A cigarette purchase task (CPT) aims to characterize individual variation in the reinforcing value of tobacco. This meta-analysis estimated the associations between cigarette demand, tobacco consumption and nicotine dependence using this task. DESIGN: A meta-analysis of cross-sectional studies identified by PubMed and PsycINFO databases was conducted. Fixed- and random-effects models were used. The study also examined the model used to derive elasticity of demand (exponential or exponentiated) as a potential moderator. Publication bias was assessed using 'fail-safe N', Begg-Mazumdar test, Egger's test, Tweedie's trim-and-fill approach and meta-regression of publication year with effect size. SETTING: Studies from any setting that reported coefficient correlations on the tested associations. PARTICIPANTS: Daily cigarette users (i.e. 5 to 38 cigarettes per day; n = 7649). MEASUREMENTS: Cigarette consumption, nicotine dependence and five tobacco demand indicators: intensity (i.e. consumption at no cost), elasticity (i.e. sensitivity to rises in costs), Omax (maximum expenditure), Pmax (i.e. price at which consumption becomes elastic) and breakpoint (i.e. price at which consumption ceases). FINDINGS: Twenty-three studies met inclusion criteria. All the CPT indices were significantly correlated with smoking behavior (rs = 0.044-0.572, Ps = 0.012-10-8 ). Medium-to-large effect size associations were present for intensity, Omax, and elasticity, whereas small effects were obtained for breakpoint and Pmax . Evidence of a moderating effect of the different elasticity modeling approaches was not present. There was limited evidence of publication bias. CONCLUSIONS: All five demand indices derived from the cigarette purchase task by (CPT) were robustly associated with cigarette consumption and tobacco dependence. Of the demand indices, maximum expenditure, intensity and elasticity exhibited the largest magnitude associations.

RESUMO

INTRODUCTION: Smoke-free policies have been introduced in prisons internationally. However, high rates of relapse to smoking after release from prison indicate that these policies typically result in short-term smoking cessation only. These high rates of relapse, combined with a lack of investment in relapse prevention, highlight a missed opportunity to improve the health of a population who smoke tobacco at two to six times the rate of the general population. This paper describes the rationale and design of a randomised controlled trial, testing the effectiveness of a caseworker-delivered intervention promoting smoking cessation among former smokers released from smoke-free prisons in Victoria, Australia. METHODS AND ANALYSIS: The multicomponent, brief intervention consists of behavioural counselling, provision of nicotine spray and referral to Quitline and primary care to promote use of government-subsidised smoking cessation pharmacotherapy. The intervention is embedded in routine service delivery and is administered at three time points: one prerelease and two postrelease from prison. Control group participants will receive usual care. Smoking abstinence will be assessed at 1 and 3 months postrelease, and confirmed with carbon monoxide breath testing. Linkage of participant records to survey and routinely collected administrative data will provide further information on postrelease use of health services and prescribed medication. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Corrections Victoria Research Committee, the Victorian Department of Justice Human Research Ethics Committee, the Department of Human Services External Request Evaluation Committee and the University of Melbourne Human Research Ethics Committee. Results will be submitted to major international health-focused journals. In case of success, findings will assist policymakers to implement urgently needed interventions promoting the maintenance of prison-initiated smoking abstinence after release, to reduce the health disparities experienced by this marginalised population.

RESUMO

BACKGROUND: This study determined if a within-session dose-reduction design sufficiently captures elasticity of demand for nicotine in male and female rats using environmental enrichment to manipulate demand elasticity. METHODS: Male and female Sprague-Dawley rats were trained to self-administer nicotine (60 µg/kg/infusion). In Experiment 1, rats began daily dose-reduction for nine sessions following acquisition. Rats then underwent a minimum of five within-session dose-reduction sessions where each dose was available for 10 min. In Experiment 2, rats were reared in isolated, social, or enriched housing followed by acquisition of nicotine self-administration. Rats then underwent within-session dose-reduction. Housing environments were then switched, followed by additional testing sessions. Consumption was calculated for each dose and exponential demand curves were fit. RESULTS: No sex differences in acquisition of nicotine self-administration were detected for either experiment. In experiment 1, demand intensity (Q0; estimated intake if nicotine were freely available), was higher with between- compared to within-session dose-reduction, although elasticity of demand (α; rate of decline in nicotine intake as a function of increasing unit price), was lower. In Experiment 2, animals reared in enrichment had fewer infusions during acquisition compared to animals in isolation. Enriched males had reduced demand intensity compared to both isolated and social males, whereas isolated females had reduced intensity compared to enriched females. CONCLUSIONS: The within-session dose-reduction procedure for nicotine self-administration replicated effects of environmental enrichment on consumption behaviors. Additionally, this procedure captured differences in nicotine demand due to sex, laying important groundwork for future translational research on mechanisms of nicotine dependence.

RESUMO

In 2013 the U.S. Food and Drug Administration and National Institutes of Health established fourteen Tobacco Centers of Regulatory Science (TCORS) to advance scientific knowledge relevant to conducting evidence-based tobacco regulation. This report reviews TCORS-funded research with adult vulnerable populations. The literature search included a list of all TCORS-funded publications compiled by the TCORS coordinating center; all TCORS were requested to share publications not in the coordinating-center's list. Only TCORS-funded reports describing an empirical study with an adult vulnerable population published in a peer-reviewed journal between September 2013 and June 2018 were included. 71 reports met inclusion criteria; 39% (28/71) examined tobacco use among those with mental health and medical comorbidities, 34% (24/71) socioeconomic disadvantage, 31% (22/71) women of reproductive age, 30% (21/71) racial/ethnic minorities, 18% (13/71) rural residents, and 3% (2/71) each among active military/veterans and sexual/gender minorities. Regarding scientific domains, 63% (45/71) investigated behavior, 37% (26/71) addiction, 24% (17/71) health effects, 20% (14/71) impact analyses, 18% (13/71) toxicity, 8% (6/71) marketing influences, and 7% (5/71) communications. Totals exceed 100% because some reports addressed multiple populations/domains. TCORS funding has generated a substantial, multidisciplinary body of new scientific knowledge on tobacco use in adult vulnerable populations. However, considerable variability was noted in the amount of research conducted across the various vulnerable populations and scientific domains. Most notably, relatively few studies focused on active military/veterans or sexual/gender minorities, and the scientific domains of marketing influences and communications were conspicuously underrepresented. These are important knowledge gaps to address going forward.

RESUMO

BACKGROUND: Understanding differences in nicotine dependence assessments' ability to predict smoking cessation is complicated by variation in quit attempt contexts. Pregnancy reduces this variation, as each pregnant smoker receives the same strong cessation incentive. Cigarette smoking during pregnancy (SDP) provides a powerful paradigm for analyzing the interplay between nicotine dependence measures and sociodemographics in predicting cessation failure. METHODS: Data from a female twin cohort (median birth year 1980), assessed in teens and early twenties, were merged with birth records to identify those with smoking history who experienced childbirth (N = 1657 births, N = 763 mothers). Logistic regression predicting SDP, as a function of birth record sociodemographic variables, generated a sociodemographic risk-score. Further analysis incorporated the risk-score with data from research interviews on DSM-IV-Nicotine Dependence symptom count, Heaviness of Smoking Index. RESULTS: Low maternal educational level, younger age at childbirth, and being unmarried all contributed risk for SDP. In addition to sociodemographic risk-score, the best predictors of SDP included HSI-score (OR:1.51), their two-way interaction (OR:0.39; reduced impact of dependence at intermediate-high sociodemographic risk), history of ≥ two failed quit attempts (OR:1.38), and a dummy variable for prior pregnancy at time of assessment (OR:1.82). DSM-IV-Nicotine Dependence symptoms underperformed the Heaviness of Smoking Index and did not improve prediction when added to the best model. CONCLUSIONS: The 2-item Heaviness of Smoking Index measure and report of ≥ two failed quit attempts performed best for predicting SDP. The contribution of either nicotine dependence measure to SDP risk was diminished at increased levels of sociodemographic risk.

RESUMO

Developing briefer behavioral economic measures is an important priority to ensure that these measures can be used in a variety of different contexts and to reduce participant burden. We developed and sought to validate a Brief Assessment of Cigarette Demand (BACD). A 17-item Cigarette Purchase Task (CPT) and a 3-item BACD were completed concurrently in 2 community samples of smokers (Study 1, adult smokers [n = 80] with substance use disorders; Study 2, adolescent smokers [n = 81]). Responses on the CPT and BACD were compared on the following demand indices: (a) intensity (the number of cigarettes requested at no cost), (b) Omax (the maximum expenditure on cigarettes in a 24-hr period), and (c) breakpoint (the point at which consumption is totally suppressed/no cigarettes are purchased). Correlations of demand indices with cigarettes per day and nicotine dependence were calculated. Measures of cigarette demand on the CPT and BACD were significantly correlated, albeit at very different magnitudes, for all 3 indices in the adult sample (intensity, r = .86; breakpoint, r = .23; and Omax, r = .43) and for 2 of the indices in the adolescent sample (intensity, r = .97; breakpoint, r = .33). The CPT and BACD relationships with smoking and nicotine dependence were similar for breakpoint and intensity but not for Omax. As initial findings were mixed, additional validation work is recommended to improve psychometric properties before adoption. Valid brief measures of demand could have utility for research and treatment of addictive disorders. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
