Conducta fumadora en estudiantes de kinesiología y su asociación con actitudes y conocimientos sobre tabaquismo: estudio de corte transversal / Smoking behavior in Chilean physical therapist students and their association with attitudes and knowledge on cigarette smoking: a cross sectional study

INTRODUCCIÓN: El tabaquismo continúa siendo un problema sanitario en población universitaria y profesionales de la salud. Los kinesiólogos participan en la implementación de programas orientados a la prevención y cese del tabaquismo en la comunidad. El objetivo de este estudio fue explorar la prevalencia de tabaquismo y actitudes sobre consumo de tabaco en estudiantes de kinesiología. MÉTODOS: Estudio de corte transversal realizado en estudiantes de Kinesiología de Concepción (Chile), durante los años 2017 y 2018. Se determinó la conducta y actitudes sobre tabaquismo. Mediante regresión logística se determinó la asociación entre la conducta fumadora y las actitudes sobre tabaquismo. Se consideró un valor de p < 0,05 como estadísticamente significativo. RESULTADOS: Se contestaron 554 cuestionarios. El 57,8% de los estudiantes encuestados declaró no haber fumado nunca, 13 % no haber fumado los últimos 6 meses y 29,4% declaró ser fumador actual. Por su parte, el 99,5% expresó algún grado de acuerdo con que fumar es perjudicial para la salud, lo cual se relacionó con la conducta fumadora (p < 0,0002). En relación a actitudes sobre tabaquismo, comparado a los no fumadores, los fumadores actuales presentan mayor probabilidad de mostrar desacuerdo o indiferencia respecto a actitudes positivas sobre tabaquismo. Principalmente en aquellas acciones que restringen su consumo, venta y divulgación (OR ponderado = 2,43; 95%IC 2,02 - 2,92). CONCLUSIONES: La prevalencia de tabaquismo en estudiantes de Kinesiología de Concepción es del 29,2%. Los estudiantes fumadores expresan una menor aprobación relacionada a intervenciones, actitudes y consecuencias del tabaquismo para la salud comparada con los no fumadores.

INTRODUCTION: Notwithstanding control policies, smoking continues to be a health problem in university students and health professionals, who are responsible for implementing programs oriented to prevention and cessation of smoking in the community. The objective of this study was to explore the prevalence of smoking and attitudes about smoking in physical therapy students. METHODS: Cross-sectional study carried out in students of physical therapy from three universities of Concepción city (Chile), during the years 2017 and 2018. Behavior and attitudes about smoking were evaluated. Association between smoking behavior and attitudes about smoking was determined by logistic regression. A p value < 0.05 was considered statistically significant. RESULTS: 554 questionnaires were answered. 57.8% of respondents had never smoked, 13.0% had not smoked in the last 6 months and 29.4% were current smokers. Moreover 99.5% of respondents stated some degree of agreement that smoking is harmful to health, which was related to smoking behavior (p < 0.0002). In relation to attitudes about smoking, compared to non-smokers, current smokers have a greater chance of showing disagreement or indifference regarding positive attitudes about smoking. Mainly in those actions that restrict tobacco consumption, sale and disclosure (weighted OR = 2.43, 95% CI 2.02 - 2.92). CONCLUSIONS: The prevalence of current smoking in physical therapy students from Concepcion city is 29.2%. Smoking students express lower approval related to interventions, attitudes and consequences of smoking for health compared with non-smokers.

Food Addiction and Tobacco Use Disorder: Common Liability and Shared Mechanisms.

As food addiction is being more commonly recognized within the scientific community, parallels can be drawn between it and other addictive substance use disorders, including tobacco use disorder. Given that both unhealthy diets and smoking are leading risk factors for disability and death, a greater understanding of how food addiction and tobacco use disorder overlap with one another is necessary. This narrative review aimed to highlight literature that investigated prevalence, biology, psychology, and treatment options of food addiction and tobacco use disorder. Published studies up to August 2020 and written in English were included. Using a biopsychosocial lens, each disorder was assessed together and separately, as there is emerging evidence that the two disorders can develop concurrently or sequentially within individuals. Commonalities include but are not limited to the dopaminergic neurocircuitry, gut microbiota, childhood adversity, and attachment insecurity. In addition, the authors conducted a feasibility study with the purpose of examining the association between food addiction symptoms and tobacco use disorder among individuals seeking tobacco use disorder treatment. To inform future treatment approaches, more research is necessary to identify and understand the overlap between the two disorders.

Recent findings in the pharmacology of inhaled nicotine: Preclinical and clinical in vivo studies.

INTRODUCTION: The rise of vaping in adolescents, the recent entrance of new inhaled nicotine products such as iQOS on the market and e-cigarette or vaping product use-associated lung injury cases has created concern for the use of inhaled non-combustible nicotine products. This narrative review discusses recent experimental in vivo studies that utilize human, rat and mouse models to understand the pharmacological impact of nicotine from non-combustible products. METHODS: The search engine PubMed was utilized with the following search terms: inhaled nicotine, nicotine e-cigarette, heated tobacco products, iQOS, electronic cigarette, nicotine inhaler, nicotine vaping. This review highlights recent primary in vivo studies of inhaled nicotine administration experimental paradigms that occurred in laboratory settings using human and rodent (rats and mice) models that have been published from January 2017-December 2019. RESULTS: The pharmacokinetics of nicotine via e-cigarettes is influenced by the PG/VG and flavor constituents in e-liquids, the presence of nicotine salts in e-liquids, puff topography of nicotine and tobacco product users and the power of the e-cigarette device. The pharmacodynamic impact of inhaled nicotine has cardiovascular, pulmonary and central nervous system implications. CONCLUSION: The articles reviewed here highlight the importance of both animal and human models to fully understand the impact of inhaled nicotine pharmacology There is a need for more rodent pharmacokinetic inhaled nicotine studies to understand the influences of factors such as flavor and nicotine salts. Additionally, consensus on nicotine measurement in both human and rodent studies is greatly needed.

Looming Vulnerability and Smoking Cessation Attempts.

INTRODUCTION: The looming vulnerability model holds that people become anxious when they perceive threats as growing larger and accelerating toward them in space and time. Preliminary research suggested that a guided imagery induction designed to activate a sense that health consequences of smoking are a looming threat led more smokers to attempt to quit. This study tested the effect on quit attempts in a larger sample and examined age, sex, and sensation seeking as moderators. AIMS AND METHODS: Adult smokers (≥10 cigarettes/day) screened for risk of anxiety or mood disorders (N = 278, 52% male; 77% African American) were randomly assigned to receive (1) looming vulnerability or (2) neutral guided imagery exercises. At a 4-week follow-up, they reported quit attempts, smoking rate, self-efficacy, outcome expectancies, and contemplation status. RESULTS: Those in the looming condition (17%) were no more likely than those in the control condition (20%) to make a quit attempt. There were no significant group differences in expectancies, contemplation, or follow-up smoking rate, and no significant moderators. CONCLUSIONS: The looming induction was the same one used in earlier work in which it had stronger effects. Those who respond to it with increased urgency about quitting smoking might be offset by others who are more reactant and deny the message. Inconsistencies across studies may reflect differences in inclusion criteria, such that the present sample was on average heavier smokers with longer smoking history and more severe nicotine dependence, yet higher self-efficacy. IMPLICATIONS: An induction designed to activate a sense that the health consequences of smoking constitute a looming vulnerability failed to increase quit attempts or reduce smoking rate among adult daily smokers. Inconsistencies across studies might reflect varying sample characteristics resulting from changes in screening criteria.

Social Causation, Social Selection, or Common Determinants? Examining Competing Explanations for the Link Between Young Adult Unemployment and Nicotine Dependence.

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.

Pharmacological Treatment of Youth Substance Use Disorders.

While the majority of youth who experiment with alcohol and drugs do not develop problematic levels of use, 5% of adolescents and 15% of young adults meet criteria for a substance use disorder (SUD). Pharmacotherapy, in combination with behavioral interventions, has the potential to increase the likelihood of successful treatment for youth struggling with SUD; however, the literature in this area is limited. To date, there are no Food and Drug Administration (FDA)-approved medications for adolescent SUD, other than buprenorphine, which has been approved down to 16 years of age for opioid use disorder. Despite alcohol and cannabis being the most commonly used substances during adolescence, only three medications have been tested among this demographic, and only two have warranted further study (i.e., naltrexone for alcohol and N-acetylcysteine for cannabis use disorder). Although less common in adolescents and young adults, the most promising pharmacological findings for this age group are for opioid (buprenorphine) and tobacco (bupropion and varenicline) use disorders. In addition, despite the recent marked increases in electronic nicotine delivery systems (i.e., vaping) among youth, treatment strategies are still in their infancy and no recommendation exists for how to promote cessation for youth vaping. Current findings are limited by: small, demographically homogeneous samples; few trials, including a substantial number of youth younger than 18; low retention; medication adherence rates; and minimal information on effective dosing levels and long-term outcomes. Overall, pharmacotherapy may be a potentially effective strategy to increase treatment effects; however, more rigorous research trials are warranted before FDA approval would be granted for any of the potential adjunctive medications in this age group.

Blunts versus joints: Cannabis use characteristics and consequences among treatment-seeking adults.

BACKGROUND: Despite the high prevalence of blunt smoking among cannabis users, very few studies examine the clinical profile of blunt smokers relative to those using more common methods of cannabis use, such as joints. METHODS: The current study uses baseline data from the ACCENT (Achieving Cannabis Cessation-Evaluating N-acetylcysteine Treatment) study, a multi-site randomized pharmacotherapy clinical trial within the National Drug Abuse Treatment Clinical Trials Network, to predict the association between blunt and joint use frequency and cannabis use characteristics (e.g., grams of cannabis used) and consequences (e.g., withdrawal) among past-month cannabis users (N = 377) who were screened for study participation. RESULTS: After controlling for race, age, gender, other forms of cannabis use (including joint use) and nicotine dependence, multivariable linear regression models indicated that the number of days of blunt use in the past month was a significant predictor of the average amount of cannabis per using day (t = 3.04, p < .01), the estimated average cost of cannabis (t = 2.28, p < .05) and Cannabis Withdrawal Scale scores (t = 1.94, p < .05). Frequency of joint use did not significantly predict any of the cannabis use characteristics or consequences. CONCLUSIONS: Blunt smokers may present to treatment with greater amounts of cannabis smoked and more intense withdrawal symptoms, which may adversely impact their likelihood of successful abstinence. Cannabis-dependent blunt smokers may be more likely to benefit from treatment that targets physiological and mood-related withdrawal symptoms.

Predictors of the effectiveness of acupuncture in smoking cessation in coronary patients: a prospective study of 25 patients.

BACKGROUND: Smoking cessation should be a priority for smokers, especially coronary patients. AIM: To study the place and effectiveness of acupuncture in smoking cessation in coronary patients. METHODS: We conducted a prospective open-label study of 25 coronary smokers treated by acupuncture over a 10-month period, from June 2017 to March 2018. A 2-session protocol acupuncture weekly for three to five weeks, with a positive response. In order to evaluate the effectiveness of acupuncture, a questionnaire was completed by the doctor during the treatment, at three and six months after the end of the sessions. Positive response was defined by total cessation of smoking. RESULTS: The average age of our patients was 55.5 years (33 to 77 years). The sex ratio of our population was 1.5 with a male predominance. All our patients had a coronary history. The average cigarette consumption was 22.7 pack-years on average. The results of our study showed that acupuncture allows the withdrawal of 5 smokers (20%) from the first session. After the fifth session, 60% of our patients stopped smoking. At the end of the treatment, 17 smokers (70%) stopped smoking completely. At 3 and 6 months of treatment, we observed a stabilization of smoking cessation and decrease rates. CONCLUSION: Smoking cessation is difficult to obtain whatever the therapeutic method used, which encourages us to strengthen preventive measures.

Substance Use Disorders Among Veterans in a Nationally Representative Sample: Prevalence and Associated Functioning and Treatment Utilization.

OBJECTIVE: Several epidemiological studies have reported that veterans and nonveterans have comparable substance use disorder (SUD) prevalence and SUD treatment rates for SUD and treatments of several types. No studies have compared functioning among veterans with SUD to veterans without SUD or to nonveterans. METHOD: We investigated the prevalence of past-year and lifetime SUD (based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), overall and by substance, and estimated the association with physical and mental health functioning and treatment utilization and need among veterans and nonveterans in a nationally representative sample. RESULTS: Predicted prevalence of any past-year SUD, with and without tobacco use disorder (TUD), among veterans was 32.9% and 17.1%, and prevalence of any lifetime SUD, with and without TUD, was 52.5 and 38.7%, respectively. Veterans had higher prevalence of past-year and lifetime SUD for some substances (e.g., tobacco, alcohol) but not others (e.g., cannabis, opioid). Lower physical and mental health functioning was found among veterans, relative to nonveterans, and participants with SUD, relative to those without SUD, and veterans with SUD reported the lowest functioning across all domains. More veterans than nonveterans received any SUD treatment and SUD treatment in specific domains (e.g., self-help). About 70% of veterans with past-year SUD did not receive treatment, but only 5.4% reported needing and not receiving treatment. CONCLUSIONS: Relative to nonveterans, veterans have higher prevalence of past-year TUD and lifetime alcohol use disorder or TUD and lower physical or mental health functioning. A minority of veterans receive SUD treatment, and few report unmet need for treatment.

Tobacco use during cannabis cessation: Use patterns and impact on abstinence in a National Drug Abuse Treatment Clinical Trials Network study.

BACKGROUND: It is common for cannabis users to also use tobacco. While data suggest that tobacco users have more difficulty achieving cannabis cessation, secondary analyses of clinical trial data sets may provide insight into the moderating variables contributing to this relationship, as well as changes in tobacco use during cannabis treatment. Those were the aims of this secondary analysis. METHODS: The parent study was a multi-site trial of N-acetylcysteine for cannabis dependence conducted within the National Drug Abuse Treatment Clinical Trials Network. Participants were treatment-seeking adults (ages 18-50) who met criteria for cannabis dependence (N = 302). For cigarette smokers (n = 117), tobacco use was assessed via timeline follow-back and nicotine dependence was assessed via the Fagerström Test for Nicotine Dependence (FTND). Outcome measures included: 1) changes in tobacco use based on treatment assignment, nicotine dependence, and concurrent cannabis reduction/abstinence, and 2) independent associations between nicotine dependence and cannabis abstinence. RESULTS: Cigarette smokers accounted for 39% of the sample (117/302), with a median FTND score of 3.0 (10-point scale). Among those with lower baseline nicotine dependence scores, cigarette smoking was reduced in the active treatment group compared to placebo. Those with moderate/high levels of nicotine dependence showed slight increases in smoking following active treatment. Nicotine dependence did not affect cannabis cessation. CONCLUSIONS: Cigarette smoking during cannabis treatment was affected, but depended on baseline nicotine dependence severity, though dependence levels did not impact cannabis abstinence. Interventions that address both tobacco and cannabis are needed, especially due to an increasing prevalence of cannabis use.

A Comparison of Dependence across Different Types of Nicotine Containing Products and Coffee.

INTRODUCTION: Few studies have compared the dependence to different tobacco and nicotine products. Even less is known about how it relates to dependence on other common drugs, e.g., caffeine. In this study degree of dependence was compared between snus, cigarettes, nicotine replacement (NR), electronic cigarettes and coffee. METHODS: A random sample of Swedish citizens belonging to an internet panel were contacted from September to October 2017. The responders were asked among other related things about their use of snus, NR, traditional cigarette or e-cigarette use and coffee consumption. The indicators of dependence used were: (A) the Heavy Smoking Index, (B) The proportions that used within 30 min after raising in the morning, (C) rating the first use in the morning as the most important and (D) Stating that it would be very hard to give up entirely. RESULTS: Significantly fewer coffee drinkers started use within 30 min of awakening compared with all other products. The first use of the day was found to be more important for snus users compared with other products. On HSI there was no difference between snus and cigarettes. Snus and cigarettes were rated as being more difficult to give up than NR and coffee. CONCLUSION: Dependence to traditional cigarettes and snus seem to be relatively similar while NR was rated lower and coffee lowest. Since the prevalence of caffeine use in all forms is so much more prevalent than nicotine there might be more persons in the society heavily dependent on caffeine. IMPLICATION: Tobacco products are likely more dependence forming than NR products and coffee although there might be more people dependent on caffeine. The addiction to coffee or caffeine is seldom discussed in the society probably because of the little or no harm it causes. FUNDING: The Snus Commission in Sweden (snuskommissionen) funded the data collection. No funding used for the analysis and writing of manuscript.

Risk factors for bruxism

The aim of the present study was to summarize the risk factors for bruxism that were identified by a systematic search of the literature published between 2007 and 2016. Depending on the size of the odds ratios (ORs) and the lower limit of the 95% confidence intervals indicated by the reports, four risk categories were differentiated. Among others, emotional stress, consumption of tobacco, alcohol, or coffee, sleep apnea syndrome, and anxiety disorders were recognized as important factors among adults. In children and adolescents, apart from distress, behavioral abnormalities and sleep disturbances predominated. Knowledge of the identified risk factors may be useful when taking the medical history of bruxing patients. Although many of the described variables cannot be influenced by prophylactic or therapeutic means, we recommend the following patient-centered approach ("SMS therapy"): self-observation, muscle relaxation, stabilization (Michigan) splint.

Guía de estilos de vida y glaucoma (II). Dieta, suplementos, drogas, sueño, embarazo e hipertensión arterial / Lifestyles guide and glaucoma (II). Diet, supplements, drugs, sleep, pregnancy, and systemic hypertension

Objetivos: Establecer guías para aconsejar a los pacientes respecto a la relación entre dieta y hábitos de vida y glaucoma. Métodos: Revisión de los trabajos publicados sobre glaucoma y la dieta, la ingesta de suplementos, el consumo de drogas o el tabaco, el sueño, el embarazo y la hipertensión. Los trabajos fueron clasificados según el Oxford Center for Evidence-Based Medicine. Resultados: La evidencia sobre la relación entre la dieta o el uso de suplementos y la incidencia o la progresión del glaucoma es insuficiente para justificar una recomendación. Si bien algunos estudios en glaucoma de tensión normal sugieren que el Ginkgo biloba podría reducir la progresión, no permiten recomendar su uso generalizado. Los estudios sobre tabaco no demuestran claramente una relación entre consumo de tabaco e incidencia del glaucoma. La marihuana no es un tratamiento útil para el glaucoma. Los resultados sobre la relación entre la apnea del sueño y glaucoma son heterogéneos, pero sí parece conveniente que los pacientes con grado moderado o severo de apnea sean evaluados para descartar glaucoma. El embarazo no suele afectar al curso de la enfermedad, pero varios medicamentos hipotensores pueden ser nocivos para el feto. La hipotensión nocturna es un factor de riesgo de empeoramiento del glaucoma. Conclusiones: Ciertas costumbres, circunstancias o enfermedades pueden tener una influencia en la aparición o progresión del glaucoma. Es importante conocer la evidencia científica existente para poder aconsejar adecuadamente a los pacientes (AU)

To establish evidence based guidelines to advise patients on the relationship between habits, diet, certain circumstances, diseases and glaucoma. Methods: Review of all published articles on glaucoma and sports or other activities. The papers were classified according to the level of scientific evidence based on the Oxford Centre for Evidence-based Medicine classification. Results: The evidence on the relationship between diet or supplements and the incidence or progression of glaucoma is insufficient to make a general recommendation for glaucoma patients. Although some studies on normal tension glaucoma suggest that Gingko biloba could reduce glaucoma progression, the results do not allow a general recommendation for all these patients. Similarly, the evidence on the usefulness of vitamin supplements is not conclusive. The studies on smoking do not clearly demonstrate the relationship between this habit and incidence of glaucoma. Marihuana is not a useful treatment for glaucoma. Although the results on the relationship between sleep apnoea and glaucoma are heterogeneous, it is recommended that patients with moderate to intense apnoea are tested for glaucoma. Pregnancy does not influence the course of the disease, but several hypotensive drugs may be harmful for the foetus. Nocturnal systemic hypotension is a risk factor for glaucoma progression. Conclusions: Certain habits, circumstances, or diseases may have an influence on the onset or progression of glaucoma. It is important to have adequate information about the scientific evidence in the publications in order to properly advise patients (AU)

Prevalence and correlates of treatment utilization among adults with cannabis use disorder in the United States.

BACKGROUND: The increase in cannabis potency may have treatment implications for cannabis use disorder (CUD). Given the reported increase in prevalence of cannabis use among adults, there is a need to understand substance use treatment needs for CUD. METHODS: We examined demographics and behavioral health indicators of adults aged ≥18 years that met criteria for past-year CUD (n=10,943) in the 2005-2013 National Surveys on Drug Use and Health. We determined prevalence and correlates of past-year treatment use for alcohol/drug, any drug, and cannabis use related problems, to inform treatment efforts for CUD. RESULTS: The majority of adults with past-year CUD were young adults aged 18-25 or men, had low income, and did not attend college. Two-thirds of adults with CUD met criteria for cannabis dependence, which was comparatively common among younger adults, women, low-income or publicly insured adults, and college-educated adults. Nicotine dependence (40.92%) and alcohol (44.07%) or other drug use disorder (19.70%) were prevalent among adults with CUD. Overall, less than 13% of adults with CUD had received alcohol/drug use treatment the past year; only 7.8% received cannabis-specific treatment. There was no significant yearly variation in treatment use prevalence over 9 years. In particular, Asian-Americans, women, and college-educated adults underutilized cannabis-specific treatment. CONCLUSIONS: This large sample of adults with CUD reveals pervasive underutilization of cannabis-related treatment, especially in women, married adults, and those with college education, despite a high proportion of comorbid behavioral health problems.

Drug addiction and diabetes: South Asian action.

Both diabetes and drug addiction are common phenomena across the world. Drug abuse impacts glycaemic control in multiple ways. It becomes imperative, therefore, to share guidance on drug deaddiction in persons with diabetes. The South Asian subcontinent is home to specific forms and patterns of drug abuse. Detailed study is needed to ensure good clinical practice regarding the same. This communication provides a simple and pragmatic framework to address this issue, while calling for concerted action on drug deaddiction in South Asia.

If at first you don't succeed: characterization of smokers with late smoking abstinence onset.

INTRODUCTION: Most cigarette smoking cessation research has aimed to clarify characteristics associated with initial and sustained abstinence, with less attention paid to predictors of gaining abstinence following an initial failure. METHODS: The current investigation explored pre-treatment demographic, smoking, and psychiatric characteristics related to gaining abstinence among smokers who failed to attain initial abstinence. Participants were 809 individuals enrolled in extended, 52-week, smoking cessation interventions. Of these, 287 (62.4%) failed to achieve initial abstinence. Gaining abstinence following initial abstinence failure was defined as achieving seven-day point prevalent abstinence at any post-initial abstinence assessment. RESULTS: Those who gained abstinence (Gainers) were more likely to have a live-in partner (χ(2)(1, N=283)=3.8, p=.05, Cramér's V=.12), identify as Hispanic (χ(2)(1, N=281)=7.8, p<.01, Cramér's V=.17), evidence lower baseline expired breath carbon monoxide (F(1, 284)=5.7, p=.02, η(2)=.02), report less cigarette dependence (F(1, 278)=7.1, p<.01, η(2)=.03), and report past week cannabis use (χ(2)(1, N=284)=5.6, p=.02, Cramér's V=.14). A logistic regression model suggested that having a live-in partner (OR=5.14, 95% CI=1.09-3.02, p=.02) and identifying as Hispanic (OR=4.93, 95% CI=1.20-18.77, p=.03) increased the odds of gaining abstinence. DISCUSSION: Having a live-in partner, Hispanic status, greater cigarette dependence, and recent cannabis use were associated with gaining abstinence. These findings provide insight into an understudied area, contributing an initial framework toward understanding gaining abstinence following initial failure.

The role of fear and disgust in predicting the effectiveness of television advertisements that graphically depict the health harms of smoking.

INTRODUCTION: Antismoking television advertisements that depict the graphic health harms of smoking are increasingly considered best practices, as exemplified by the Centers for Disease Control and Prevention's current national campaign. Evaluation of responses to these widely used advertisements is important to determine advertisements that are most effective and their mechanisms of action. Our study tested the hypothesis that advertisements rated highest in fear- and disgust-eliciting imagery would be rated as the most effective. METHODS: Our laboratory study included 144 women and men aged 18 to 33; 84% were current nonsmokers. All participants viewed 6 antismoking television advertisements that depicted the health harms of smoking; they rated their responses of fear and disgust and the effectiveness of the advertisements. We used multilevel modeling to test the effects of the following in predicting effectiveness: fear, disgust, the fear-disgust interaction, the advertisement, and the participant's sex and smoking status. Follow-up analyses examined differences in ratings of fear, disgust, and effectiveness. RESULTS: Advertisement, fear, disgust, and the fear-disgust interaction were each significant predictors of effectiveness. Smoking status and sex were not significant predictors. The 3 advertisements that elicited the highest ratings of fear and disgust were rated the most effective. CONCLUSION: Our findings support the hypothesis that antismoking advertisements of health harms that elicit the greatest responses of fear or disgust are the most effective. When advertisements elicit high ratings of both fear and disgust, advertisements with graphic imagery are effective, whereas advertisements without graphic imagery are not.

Impact of a long-term tobacco-free policy at a comprehensive cancer center: a series of cross-sectional surveys.

BACKGROUND: Spain has passed two smoke-free laws in the last years. In 2005, the law banned smoking in indoor places, and in 2010 the ban was extended to outdoor areas of certain premises such as hospitals. This study assesses the impact of smoking consumption among hospital workers at a comprehensive cancer center after the passage of two national smoke-free laws. METHODS: Six cross-sectional surveys were conducted among a representative sample of hospital workers at a comprehensive cancer center in Barcelona (2001-2012) using a standardized questionnaire. Logistic regression was used to compare differences in the odds of smoking after the laws took effect (baseline vs. 1st law; 2nd law vs. 1st law). RESULTS: Baseline smoking prevalence was 33.1%. After passage of the 1st and 2nd laws, prevalence decreased, respectively, to 30.5% and 22.2% (p for trend =0.005). Prevalence ratios (PR) indicated a significant decrease in overall smoking after the 2nd law (PR = 0.65, 95% CI = 0.47-0-89). Smoking dropped in all professional groups, more prominently among those ≥35 years old, doctors, and women. Observed trends over the time included an increase in occasional smokers, a rise in abstinence during working hours but an increase in smoking dependence, and an increase in the employees' overall support for the smoke-free hospital project. CONCLUSIONS: A long-term tobacco control project combined with two smoke-free national laws reduced smoking rates among health workers and increased their support for tobacco control policies. The decrease was more significant after the passage of the outdoor smoke-free ban.

Epidemiology of chronic kidney disease in adults of Salvadoran agricultural communities.

INTRODUCTION: In El Salvador, chronic kidney disease is a serious and growing public health problem. Chronic renal failure was the first cause of hospital deaths in men and the fifth in women in 2011. OBJECTIVE: Determine prevalence of CKD, CKD risk factors (traditional and nontraditional) and renal damage markers in the adult population of specific rural areas in El Salvador; measure population distribution of renal function; and identify associated risk factors in CKD patients detected. METHODS: A cross-sectional analytical epidemiological study was conducted based on active screening for chronic kidney disease and risk factors in persons aged ≥18 years during 2009-2011. Epidemiological and clinical data were gathered through personal history, as well as urinalysis for renal and vascular damage markers, determinations of serum creatinine and glucose, and estimation of glomerular filtration rates. Chronic kidney disease cases were confirmed at three months. Multiple logistical regression was used for statistical analysis. RESULTS: Prevalence of chronic kidney disease was 18% (23.9% for men and 13.9% for women) in 2388 persons: 976 men and 1412 women from 1306 families studied. Chronic kidney disease with neither diabetes nor hypertension nor proteinuria ≥1 g/L (51.9%) predominated. Prevalence of chronic renal failure was 11% (17.1% in men and 6.8% in women). Prevalence of renal damage markers was 12.5% (higher in men): microalbuminuria, 6.9%; proteinuria (0.3 g/L), 1.7%; proteinuria (1g/L), 0.6%; proteinuria (2 g/L), 0.4 %; and hematuria, 1.5%. Prevalence of chronic kidney disease risk factors was: diabetes mellitus, 9%; hypertension, 20.9%; family history of chronic kidney disease, 16.5%; family history of diabetes mellitus, 18.5%; family history of hypertension, 30.6%; obesity, 21%; central obesity, 24.9%; NSAID use, 84.2%; smoking, 9.9%; alcohol use, 15%; agricultural occupation, 31.2%; and contact with agrochemicals, 46.7%. Chronic kidney disease was significantly associated with male sex, older age, hypertension, agricultural occupation, family history of chronic kidney disease and contact with the agrochemical methyl parathion. CONCLUSIONS: The results of this study support suggestions from other research that we are facing a new form of kidney disease that could be called agricultural nephropathy.
