Prevalence, patterns, and determinants of electronic cigarette and heated tobacco product use in Greece: A cross-sectional survey.

BACKGROUND: Electronic cigarettes (EC) and heated tobacco products (HTP) have been introduced in the global market as safer nicotine delivery systems; however, there is skepticism about their link to smoking and long-term risks. The aim of this study was to evaluate the prevalence, patterns, and determinants of EC/HTP use in Greece. METHODS: This was a cross-sectional survey of 1,044 individuals aged ≥15 years old, who were randomly selected from the general Greek population. The study was conducted in May 2022, and participants were assessed through face-to-face interviews using a questionnaire designed to collect information on smoking and EC/HTP use, as well as their sociodemographic, lifestyle, and medical data. RESULTS: The use of EC/HTP was reported by 16.2% of the participants, slightly more prevalent in males (17.2%) than in females (15.2%), and significantly more prevalent in <40-year-olds (21.3%) than ≥40-year-olds (11.3%). Most EC/HTP users (72.8%) were current smokers, 13.0% were former smokers, and 14.2% were never smokers. Among users, 60.6% used nicotine-containing products, 30.2% used EC/HTP in parallel with conventional tobacco, and 56.9% used EC/HTP for the first time while being <25 years old. In multiple logistic regression analysis, younger age, being employed, being a former/current smoker, adopting a Western-type diet, and believing that EC/HTP are less harmful than conventional tobacco products and can help toward smoking cessation emerged as significant determinants of EC/HTP use. CONCLUSIONS: EC/HTP are commonly used in combination with conventional tobacco, are quite popular among the youth, and also appeal to a small fraction of nonsmokers.

Tobacco products in the European Union Common Entry Gate (EU-CEG): A tool for monitoring the EU tobacco products directive.

INTRODUCTION: Under the European Union (EU) Tobacco Products Directive (2014/40/EU) (TPD), manufacturers and importers of tobacco products are required to report information to the European Commission (EC) and Member States (MS) on products intended to be placed on the market. We describe the distribution of notifications to the EU Common Entry Gate (EU-CEG) and identify key fields for improvement on reporting cigarettes or roll-your-own (RYO) tobacco. METHODS: A cross-sectional analysis of secondary data reported in the EU-CEG was conducted for tobacco products notified within EU-CEG between June 2016 and October 2019 for 12 EU MS. Analysis of compliance to specific regulations for priority additives that refer to cigarettes and RYO was conducted for 10 EU countries. RESULTS: Overall, 39170 tobacco products were notified. This included 16762 (42.8%) notifications of cigars, followed by cigarettes 11242 (28.7 %), waterpipes 3291 (8.4%), cigarillos (n=1783), pipe (n=1715), RYO (n=1635), chewing tobacco (n=1021), novel tobacco products (n=839), herbal products for smoking (n=535), other (n=258), nasal (n=74) and oral tobacco (n=15). In cigarettes and RYO tobacco products, the proportion of ingredients notified in all countries that contained an unknown Chemical Abstract Services (CAS) number was 3.8% and 2.1%, respectively. The proportion of underreporting flagging of priority additives ranged from 15.9% in Malta to 41.3% in Lithuania, the mean proportion of underreporting of the variable 'priority additive' for the 10 countries together was 24.7%. CONCLUSIONS: In the EU-CEG data base, for the period of analysis, a significant number of product notifications took place while large variations in the number of types of tobacco products notified across EU countries was noted. The timely monitoring of these data is needed so that products non-compliant within the EU-CEG system are assessed.

Mortality and morbidity from infectious and non-communicable diseases in Greece during Axis/Nazi military occupation (1941-1944).

Greece has been severely damaged by the Second World War and the subsequent military occupation of the country by the Axis forces headed by Nazi Germany. The Greek society and economy were dislocated as a result of plundering of the country's vital resources, as well as enforced payments, instead paid to the occupying forces. The dramatic food shortages and famine appeared plaguing especially large cities. There is very limited information on the trends of mortality and morbidity (1941-1944) at a national level. The morbidity and mortality statistics of the General Statistical Service of Greece were assessed and the incidence morbidity and mortality rates have been calculated. As denominator population we used the population of Greece according to 1940 census. The morbidity due to exanthematic typhus, typhoid fever, dysentery and meningitis has been elevated over the period 1940-1944. An elevated specific mortality due to tuberculosis, malaria and typhoid fever was observed over the period 1940-1941. Regarding non-communicable diseases, the mortality due to hemorrhagic stroke was increased after 1940. In conclusion, we found that the Axis/Nazi military occupation of Greece had considerable health effects on infectious diseases and hemorrhagic stroke mortality. Deaths ostensibly due to infectious diseases (e.g. tuberculosis or malaria), were expedited by the hunger famine of the period under investigation. With regard to the elevated mortality due to hemorrhagic stroke, we believe that the stressful events of occupation and famine have triggered increased psychosocial stress which in turn may have increased the risk of hemorrhagic stroke mortality during the period of Axis/Nazi occupation of Greece.

Reporting system of suspected adverse effects from electronic cigarettes and refill liquids in Europe.

In line with Article 20 (9) of the Tobacco Products Directive (TPD) 2014/40/EU, a guidance document outlining a reporting system of suspected adverse effects from electronic cigarettes and their refill liquids was produced by Work Package 4 entitled 'Integration into national policies and sustainability' of the Joint Action on Tobacco Control (JATC). The JATC was a European project that lasted three years (2017-2020), with the general objective of providing support for the implementation of the TPD throughout the 27 European Union Member States (EU MS). The reporting system described in the guidance document includes a short reporting template for the reporting of adverse effects on human health from electronic cigarettes and refill liquids, both by Economic Operators (EO) and by National Competent Authorities (NCA). The present guidance document aims at providing the necessary steps and modalities that each MS should follow if involved in the development of a system for the reporting of suspected adverse effects on human health from electronic cigarettes and refill liquids.

Perceived Importance of Public Health Risks in Greece: A Nationwide Survey of the Adult Population.

The current study is the first to examine the perceptions of the Greek public towards selected health risks and prioritize perceived risk importance and the needs to be addressed for public health promotion. Participants were asked to consider the individual importance of selected risks and the top three most important risks. Data collection took place on February 2020 in a representative sample of the adult Greek population. Differences between groups were assessed with Chi-square tests. Logistic regression models were used to identify perceptions based on participants' characteristics. Analysis was conducted in Stata 14, and 1976 adults participated in the survey: 48% male and 52% female. Road accidents, cancer and air pollution and environmental protection were considered the top three most important public health risks. Differences were observed between sexes; females were more concerned regarding the importance of the examined public health risks, and between age groups, younger ages considered STDs and contraception more important than older ages. Finally, non-smokers considered exercise and smoking to be more important than smokers. This is the first study to present and grade the public's perceptions on the importance of public health risks in Greece. Our study's prioritization of health risks could aid health authorities in improving and promoting the overall public health in Greece.

Driving Behavior That Limits Concentration: A Nationwide Survey in Greece.

Human behavior is implicated in most road accidents. The current study examined drivers' behavior that interferes with decision making and reaction time to an incidence. Adults (≥17 years-old) participated in a questionnaire-based survey for driver's behavior. Dataset was weighed according to sex, age and education based on the 2011 census. Differences between groups were assessed with Chi-squared tests while logistic regression models were used to identify drivers' characteristics for specific behaviors. A total 1601 adults participated in the survey-48% males and 52% females. Texting, Global Positioning System (GPS) setting and smoking were observed more by professional drivers and drivers of an urban area, while smoking was also dependent on social class. Drink driving was observed more by males (20% vs. 5% females), while after adjusting for age, the odds of drink driving in males were 5 times higher than females (p < 0.001). A different effect of age depending on the driver's sex and vice versa was observed regarding phone calls. Drivers' behavior with distractive potential differed by age, sex, social class and area of residence. Male drivers were more likely to perform drink driving, while professional drivers were more likely to use cell phone for calls and texting, set the GPS and smoke while driving.

Who Smokes in Europe? Data From 12 European Countries in the TackSHS Survey (2017-2018).

BACKGROUND: Population data on tobacco use and its determinants require continuous monitoring and careful inter-country comparison. We aimed to provide the most up-to-date estimates on tobacco smoking from a large cross-sectional survey, conducted in selected European countries. METHODS: Within the TackSHS Project, a face-to-face survey on smoking was conducted in 2017-2018 in 12 countries: Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania, and Spain, representing around 80% of the 432 million European Union (EU) adult population. In each country, a representative sample of around 1,000 subjects aged 15 years and older was interviewed, for a total of 11,902 participants. RESULTS: Overall, 25.9% of participants were current smokers (31.0% of men and 21.2% of women, P < 0.001), while 16.5% were former smokers. Smoking prevalence ranged from 18.9% in Italy to 37.0% in Bulgaria. It decreased with increasing age (compared to <45, multivariable odds ratio [OR] for ≥65 year, 0.31; 95% confidence interval [CI], 0.27-0.36), level of education (OR for low vs high, 1.32; 95% CI, 1.17-1.48) and self-rated household economic level (OR for low vs high, 2.05; 95% CI, 1.74-2.42). The same patterns were found in both sexes. CONCLUSIONS: These smoking prevalence estimates represent the most up-to-date evidence in Europe. From them, it can be derived that there are more than 112 million current smokers in the EU-28. Lower socio-economic status is a major determinant of smoking habit in both sexes.

Current practices and perceived barriers to tobacco-treatment delivery among healthcare professionals from 15 European countries. The EPACTT Plus project.

INTRODUCTION: The latest evidence-based Guidelines for Treating Tobacco Dependence highlight the significant role of healthcare professionals in supporting smokers interested to quit. This study aimed to identify the current practices of healthcare professionals in Europe and perceived barriers in delivering tobacco treatment to their patients who smoke. METHODS: In the context of EPACTT-Plus, collaborating institutions from 15 countries (Albania, Armenia, Belgium, Italy, France, Georgia, Greece, Kosovo, Romania, North Macedonia, Russia, Serbia, Slovenia, Spain, Ukraine) worked for the development of an accredited eLearning course on Tobacco Treatment Delivery available at http://elearning-ensp.eu/. In total, 444 healthcare professionals from the wider European region successfully completed the course from December 2018 to July 2019. Cross-sectional data were collected online on healthcare professionals' current practices and perceived barriers in introducing tobacco-dependence treatment into their daily clinical life. RESULTS: At registration, 41.2% of the participants reported having asked their patients if they smoked. Advise to quit smoking was offered by 47.1% of the participants, while 29.5% reported offering assistance to their patients who smoked in order to quit. From the total number of participants, 39.9% regarded the lack of patient compliance as a significant barrier. Other key barriers were lack of: interest from the patients (37.4%), healthcare professionals training (33.1%), community resources to refer patients (31.5%), and adequate time during their everyday clinical life (29.7%). CONCLUSIONS: The identification of current practices and significant barriers is important to build evidence-based guidelines and training programs (online and/or live) that will improve the performance of healthcare professionals in offering tobacco-dependence treatment for their patients who smoke.

Burden of disease from breast cancer attributable to smoking and second-hand smoke exposure in Europe.

Smoking and second-hand smoke (SHS) exposure have been recently linked to a higher risk of breast cancer in women. The aim of this work is to estimate the number of deaths and disability-adjusted life years (DALYs) from breast cancer attributable to these two risk factors in the European Union (EU-28) in 2017. The comparative risk assessment method was used. Data on prevalence of smoking and SHS exposure were extracted from the Eurobarometer surveys, relative risks from a recent meta-analysis, and data on mortality and DALYs from breast cancer were estimated from the Global Burden of Disease, Injuries and Risk Factors Study. In 2017, 82 239 DALYs and 3354 deaths from breast cancer in the EU-28 could have been avoided by removing exposure to these two risk factors (smoking and SHS exposure). The proportion of DALYs from breast cancer lost respectively from smoking and SHS exposure was 2.6% and 1.0%, although geographically distributed with significant heterogeneity. These results represent the first estimates of breast cancer burden in women attributable to smoking and SHS exposure for the EU-28. It is important to increase awareness among women, health professionals and wider society of the association between smoking, SHS exposure and breast cancer, a relationship that is not widely recognised or discussed.

Impact of the ENSP eLearning platform on improving knowledge, attitudes and self-efficacy for treating tobacco dependence: An assessment across 15 European countries.

INTRODUCTION: In 2018, the European Network for Smoking Cessation and Prevention (ENSP) released an update to its Tobacco Treatment Guidelines for healthcare professionals, which was the scientific base for the development of an accredited eLearning curriculum to train healthcare professionals, available in 14 languages. The aim of this study was to evaluate the effectiveness of ENSP eLearning curriculum in increasing healthcare professionals' knowledge, attitudes, self-efficacy (perceived behavioral control) and intentions in delivering tobacco treatment interventions in their daily clinical routines. METHODS: We conducted a quasi-experimental pre-post design study with 444 healthcare professionals, invited by 20 collaborating institutions from 15 countries (Albania, Armenia, Belgium, Italy, France, Georgia, Greece, Kosovo, Romania, North Macedonia, Russia, Serbia, Slovenia, Spain, Ukraine), which completed the eLearning course between December 2018 and July 2019. RESULTS: Healthcare professionals' self-reported knowledge improved after the completion of each module of the eLearning program. Increases in healthcare professionals' self-efficacy in delivering tobacco treatment interventions (p<0.001) were also documented. Significant improvements were documented in intentions to address tobacco use as a priority, document tobacco use, offer support, provide brief counselling, give written material, discuss available medication, prescribe medication, schedule dedicated appointment to develop a quit plan, and be persistent in addressing tobacco use with the patients (all p<0.001). CONCLUSIONS: An evidence-based digital intervention can be effective in improving knowledge, attitudes, self-efficacy and intentions on future delivery of tobacco-treatment interventions.

Tackling second-hand exposure to tobacco smoke and aerosols of electronic cigarettes: the TackSHS project protocol / Abordando la exposición a las emisiones del tabaco y de los cigarrillos electrónicos: protocolo del proyecto TackSHS

OBJECTIVE: The TackSHS project aims to comprehensively elucidate the impact that exposure to second-hand smoke (SHS) from cigarettes and second-hand aerosols (SHA) from electronic cigarettes have on the respiratory health of the European population according to socioeconomic characteristics and other determinants. METHOD: The TackSHS project involves a series of coordinated studies carried out by 11 academic and public health organisations from six European countries. The project will investigate: a) the determinants of SHS and SHA exposure assessed at the individual level (surveys on representative general population samples) and in common environments (environmental sampling in specific settings); b) the overall disease burden, mortality and morbidity attributable to such exposure; and c) its economic impact in terms of direct health care costs. The project will also examine specific acute respiratory health changes in healthy individuals and patients with respiratory diseases exposed to SHS and SHA. In addition, the project will examine the effectiveness of a novel intervention to reduce SHS exposure in households where smoking is permitted. All these studies are inter-related and involve collaborative coordination among the participant organisations. CONCLUSIONS: The comprehensive, integrated approach of the TackSHS project will enable a significant step forward from the current status quo in the understanding of the impact of SHS and SHA exposure on health and provide the basis for health policy recommendations to help European countries to further reduce the harm caused by SHS and SHA exposure

OBJETIVO: El proyecto TackSHS pretende caracterizar el impacto global de la exposición al humo ambiental de tabaco (HAT) y al aerosol de los cigarrillos electrónicos (ACE) en la salud respiratoria de la población europea según variables socioeconómicas y otros determinantes. MÉTODO: El proyecto TackSHS consiste en una serie de estudios coordinados y gestionados por 11 organizaciones académicas y de salud pública de seis países europeos. El proyecto estudiará: a) los determinantes de la exposición al HAT y al ACE a nivel individual (encuestas en muestras representativas de la población general) y en espacios comunes (muestras ambientales en lugares específicos); b) su carga general de enfermedad y la morbimortalidad atribuible a tal exposición; y c) su impacto económico en términos de costes sanitarios directos e indirectos. Además, el proyecto investigará cambios específicos a corto plazo en la salud respiratoria en personas sanas y en pacientes con enfermedades respiratorias expuestos al HAT y al ACE. También examinará la efectividad de una intervención novedosa para reducir la exposición al HAT en hogares donde se permite fumar. Todos estos estudios están interrelacionados y conllevan una coordinación colaborativa entre las instituciones participantes. CONCLUSIÓN: El enfoque integral del proyecto TackSHS permitirá un avance significativo en la evidencia sobre la comprensión del impacto de la exposición al HAT y al ACE en la salud, y proporcionará una base para desarrollar recomendaciones políticas sanitarias para ayudar a los países europeos a reducir los daños causados por la exposición al HAT y al ACE

Interval exercise induces milder respiratory responses compared to continuous exercise.

The purpose of this study was to explore the respiratory response of acute interval and continuous exercise (CE) of low and high intensity. Fourteen recreational athletes (7 men and 7 women; VO2max = 35.7 ± 6.1 mlkg-1min-1) performed a bout of continuous and a bout of interval exercise (IE) both consisted of 5-min cycling at low intensity [80% of the power output (W) of the predetermined gas exchange threshold (GET) (80%WGET)] and 5-min cycling at high intensity {WGET plus the work rate corresponding to 50% of the difference between peak power output (PPO) at oxygen uptake (VO2max) test and the WGET [WGET + 0.50 Δ(PPO - WGET)]}. CE compared to IE induced significant higher heart rate and ventilation as well as significant higher levels of mouth occlusion pressure for 0.1 s (P0.1) (P < 0.05) during low and high intensities. Our results indicate that CE stimulates respiration more than IE when the exercise is performed at the same relative intensity.

Passive exposure of non-smokers to E-Cigarette aerosols: Sensory irritation, timing and association with volatile organic compounds.

AIM: The current study examined symptoms of irritation reported by non-smokers passively exposed to e-cigarette aerosols and their timing and association with the concentrations of volatile organic compounds (VOCs) produced. METHODS: 40 healthy non-smoking adults were exposed to e-cigarette aerosols for 30 min in a 35 m3 room. Second-hand e-cigarette aerosol (SHA) was produced by an experienced e-cigarette user using a standardized topography and two resistance settings (exposure 0.5 Ohm and 1.5 Ohm), in addition to a control session (no emissions). PM2.5 and PM1.0 were continuously measured over the duration of exposure, while Volatile Organic Compounds (VOCs) were recorded at 0, 15 and 30 min (t0, t15 and t30) of exposure. Each participant completed an irritation questionnaire at t0, t15, t30 of exposure and t60 (30 min post-exposure) on ocular, nasal, throat-respiratory symptoms of irritation and general complaints. Kruskal-Wallis H test for PM comparisons, repeated measures ANOVA for VOCs and Generalized Estimating Equations for symptoms of irritation and association with VOCs were used for statistical analysis. RESULTS: 20 males and 20 females, with a mean age of 24.6 years (SD = 4.3) and exhaled CO < 7 ppm participated. PM concentrations in both experimental sessions were higher than the Control (p < 0.001). The most commonly reported symptoms were burning, dryness, sore throat, cough, breathlessness and headache. During both experimental sessions, ocular, nasal, throat-respiratory symptoms and general complaints increased significantly (p < 0.05). Ocular and nasal symptoms returned to baseline by t60 (p > 0.05) while throat-respiratory symptoms were still significantly higher at t60 (p = 0.044). VOCs were significantly associated with reported nasal and throat-respiratory symptoms in both experimental sessions (p < 0.05). CONCLUSION: A 30-min exposure to SHA provoked symptoms of sensory irritation and general complaints that lasted up to 30 min after the exposure and were positively associated with the concentrations of the VOC mixture emitted.

A pilot study of the Tobacco Treatment Guidelines for High-Risk Groups (TOB-G) for pregnant and postpartum women.

INTRODUCTION: Maternal smoking constitutes a significant risk to the fetus and is associated with multiple adverse pregnancy outcomes. Despite this, an estimated 6-19% of women in Europe smoke during pregnancy. We conducted a pilot study to examine the feasibility and effectiveness of the clinical practice recommendations of the 2017 Tobacco Cessation Guidelines for High-Risk Groups (TOB-G) for pregnant and postpartum women in an outpatient obstetrics setting. METHODS: The guideline recommendations were tested on a sample of 67 pregnant women recruited from obstetrics outpatient visits. Pregnant women who smoked received three behavioural counselling sessions through a combination of face-toface and telephone consultations by a midwife trained in the TOBG tobacco treatment recommendations. Smoking status was assessed at 1 month and at 6 months follow-up via self-report. RESULTS: Seventy-one per cent of pregnant smokers screened agreed to participate in the counselling intervention. Pregnant women participants (mean age, M=31.73 years, SD±6.09) smoked for an average of 12.2 (SD±6.55) years. Women reported smoking an average of 4.82 (SD±4.14) cigarettes per day with 51% reporting smoking within 30 minutes of waking, an indicator of higher levels of nicotine addiction. Rates of smoking abstinence among pregnant women undergoing the counselling intervention were 43.9% and 45.6% at the 1 month and at 6 months follow-up, respectively. Replacing those participants with missing data as smokers, the quit rates were 26.9% and 38.8% at the 1 month and 6 months follow-up, respectively. CONCLUSIONS: The counselling intervention delivered to pregnant women who smoke was feasible to implement in a manner that was consistent with the TOB-G guideline recommendations in an outpatient obstetrics setting. Future work should focus on increasing uptake of evidence-based tobacco treatment recommendations in outpatient obstetrics settings.

Impact of the Tobacco Treatment Guidelines for High Risk Groups (TOB.g): A pilot study among physicians specializing in CVD, Diabetes and COPD.

INTRODUCTION: The 2017 Tobacco Cessation Guidelines for High-risk Groups (TOB-G) is a comprehensive document on best practices for smoking cessation in clinical practice. The purpose of this pilot study was to assess physician satisfaction and changes in tobacco-related knowledge, self-efficacy and attitudes following exposure to training in the TOB-G guidelines for patients with cardiovascular disease (CVD), chronic obstructive pulmonary disease (COPD), or diabetes. METHODS: A pre-post pilot study was conducted. All participating physicians received an electronic or printed copy of the TOB-G guidelines for patients with CVD, COPD or diabetes. Physicians were also exposed to a one-day training focused on the key clinical practice recommendations from the TOB.g guidelines. Outcome measurement occurred via survey before, immediately following and 6 months after exposure to the training. RESULTS: Fifty physicians participated in the TOB.g training session. High rates of participant satisfaction were documented (exceeded expectations 47.7%; met expectations to a great extent 52.3%). Significant increases in physician knowledge and self-efficacy were documented immediately following and 6 months after exposure to the guideline training session. Exposure to the training was associated with positive changes in some but not all tobacco-related treatment attitudes, however these were no longer significant at the 6-month follow-up. Lower knowledge, confidence and unfavourable attitudes were documented for aspects of treatment related to pharmacotherapy. CONCLUSIONS: Positive changes in previously reported barriers to the delivery of tobacco treatment among physicians were documented following exposure to the TOB.g guidelines and training for patients with CVD, COPD or diabetes.

Passive exposure to e-cigarette emissions: Immediate respiratory effects.

INTRODUCTION: The present work examined the effect of passive exposure to electronic-cigarette (e-cigarette) emissions on respiratory mechanics and exhaled inflammatory biomarkers. METHODS: A cross-over experimental study was conducted with 40 healthy nonsmokers, 18-35 years old with normal physical examination and spirometry, with body mass index <30 kg/m2, who were exposed to e-cigarette emissions produced by a smoker, according to a standardized protocol based on two resistance settings, 0.5 ohm and 1.5 ohm, for e-cigarette use. All participants underwent a 30-minute control (no emissions) and two experimental sessions (0.5 and 1.5 ohm exposure) in a 35 m3 room. The following Impulse Oscillometry (IOS) parameters were measured at pre and post sessions: impedance, resistance, reactance, resonant frequency (fres), frequency dependence of resistance (fdr=R5-R20), reactance area (AX), and fractional exhaled nitric oxide (FeNO). Differences between pre and post measurements were compared using t-tests and Wilcoxon signed rank tests, while analysis of variance (ANOVA) was used for comparisons between experimental sessions (registered under ClinicalTrials.gov ID: NCT03102684). RESULTS: IOS and FeNO parameters showed no significant changes during the control session. For IOS during the 1.5 ohm exposure session, fres increased significantly from 11.38 Hz at baseline to 12.16 Hz post exposure (p=0.047). FeNO decreased significantly from 24.16 ppb at baseline to 22.35 ppb post exposure in the 0.5 ohm session (p=0.006). CONCLUSIONS: A 30-minute passive exposure to e-cigarette emissions revealed immediate alterations in respiratory mechanics and exhaled biomarkers, expressed as increased fres and reduced FeNO.

The TOBg Tobacco Treatment Guidelines for Adolescents: A real-world pilot study.

INTRODUCTION: We conducted a pilot study to: 1) obtain feedback from prevention practitioners in terms of their satisfaction, knowledge, and self-efficacy following exposure to the Tobacco Treatment Guidelines for Adolescents (TOBg Guidelines); and 2) examine the effectiveness of a school-based intervention based on the TOBg Guidelines on quit rates among a sample of adolescent tobacco users. METHODS: Two parallel studies were conducted. In Study 1, prevention practitioners were exposed to a 1-day training in the TOBg Guidelines with assessment occurring before, immediately after, and at 6 months following the training. In Study 2, participating adolescent smokers were exposed to a 3-session group-based smoking cessation intervention that drew on the TOBg Guidelines and was delivered by practitioners trained in Study 1. The primary outcome measure was self-reported smoking status assessed at 1 month and at 6 months following baseline. RESULTS: A total of 18 prevention practitioners and 65 adolescent tobacco users participated in the pilot study. The majority of practitioners reported high rates of satisfaction with the TOBg Guidelines and indicated that the guidelines positively influenced the manner in which they addressed tobacco use with adolescents. Prevention practitioners' self-efficacy for intervening with adolescent smokers was also significantly increased following exposure to the TOBg Guidelines and training. Among adolescents exposed to the school-based intervention, 62.5% and 23.1% had reduced smoking by 50% or more at 1 month and at 6 months follow-up, respectively. No significant change in smoking abstinence was documented. CONCLUSIONS: The TOBg Guidelines for adolescent smokers were well received by prevention practitioners and were feasible to implement in a real-world school setting.

Short-term impact of the EuroPean Accredited Curriculum on Tobacco Treatment Training (EPACTT) program.

INTRODUCTION: The aim of this pilot study was to assess the short-term effectiveness of the EuroPean Accredited Curriculum on Tobacco Treatment Training intervention in improving health care providers' knowledge, attitudes and self-efficacy related to tobacco dependence treatment. METHODS: A pre-post pilot study was conducted. The two-day training intervention took place in Brussels in April 2016. Health care professionals from six European countries (Russia, Ukraine, Georgia, Armenia, Romania and Greece) were purposively invited to participate in the study. Evaluation was performed before the intervention, immediately after, and at approximately two months following the intervention. Changes in outcomes of interest were examined before and after exposure to the intervention program. RESULTS: In all, 47 health care professionals participated in the training of which 40 completed the evaluation surveys. Significant increases in providers' self-efficacy and perceived behavioral control related to tobacco treatment delivery were documented immediately following the training and at the 2 months follow-up. Significant improvement in provider knowledge and attitudes were observed in some items assessed. CONCLUSIONS: The results demonstrate that training is able to improve provider self-efficacy related to tobacco treatment delivery in this cross-national European sample of health care professionals. Additional research is required to examine the generalizability of our findings.
