Filter by:This is a European study which is part of a larger research project (The TackSHS project) funded by the European Union's Horizon 2020 Research and Innovation Programme (Grant Agreement No 681040) and led by the Catalan Institute of Oncology. This study will examine the efficacy of using personalised air quality measurements in homes of smokers to encourage behaviour-change towards having a smoke-free home environment. Building on recent quantitative and qualitative work showing that feedback of second-hand smoke (SHS) measurement information can help motivate smokers to change their behaviour. This study will develop a targeted intervention for use with socio-economically deprived smokers in four countries (Scotland, Spain, Greece, Italy) across the EU. Two-hundred smokers (50 in each country) will be recruited and offered low-cost, simple to operate particle counting instruments to measure and log SHS levels in their home for a period of 30 days. During this time near real-time, personalised feedback will be provided to, and discussed with, the smoker along with target-setting and exploration of suitable methods of behaviour-change. Feedback will be given via text message to mobile phones, emails and personal voice calls. A final visit will gather data on changes made while a proportion of participants (10-20%) in each country will take part in a further qualitative interview by phone to gather data on their experience of the intervention. Study outcomes will include quantitative measures such as changes in average and maximum fine particulate matter (PM2.5) concentrations and self-declared household smoking rules, while qualitative data will be gathered using questionnaire and interview to explore what elements of the intervention were useful/unhelpful, particularly well/poorly understood, and what were the barriers for those who did not make changes. This WP will provide a comprehensive database of baseline measurements of SHS concentrations in home settings from across the EU with the potential to generate over 8 million minutes of measurements of household air quality. Analysis of the differences by country and possible determinants of exposure will be carried out.
This is a European study which is part of a larger research project (TackSHS project) funded by the European Union's Horizon 2020 Research and Innovation Programme (Grant Agreement 681040) and led by the Catalan Institute of Oncology. The main goal of the study is to assess the environmental levels of secondhand smoke (SHS) in non-regulated settings such as private and outdoor settings of 12 European countries (Bulgaria, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania, Spain and the United Kingdom) representing geographical, legislative (country-specific smoke-free policies) and cultural variations across Europe. This is a multi-country cross-sectional study based on objective environmental measurements of SHS levels. Private settings studied are homes and cars and outdoors settings are terraces of hospitality venues, children playgrounds and entrances of primary school buildings. A total of 1,080 environmental measures of airborne nicotine will be collected. 20 environmental measures will be collected from homes and each of the outdoor settings for the 12 countries involved in the study (960 samples). Regarding cars, 60 environmental measurements will be collected in two countries (Spain and the UK) (120 samples), which have been selected taking into account differences in smoke-free legislation. Further information about SHS exposure will be collected for each setting through brief questionnaires or forms. Medians and interquartile ranges of nicotine concentrations will be calculated by country for each setting studied. Nicotine concentrations will be compared using non-parametric tests according to country, socioeconomic status and other determinants of exposure for each setting.
Limited studies have evaluated potential exposure to secondhand e-cigarette aerosol, an indication of impact on indoor air quality. Also limited are the studies regarding direct passive exposure of humans and most of these studies have limitations, such as the small number of participants, the different methodology and devices used, or the fact that they are laboratory studies, where exposure parameters differ significantly from the actual user's habit and device. Therefore, TackSHS Project has foreseen an intervention study of cross-over design in similar to real-life conditions that aims to assess the mediating effect of e-cigarette battery output on pulmonary outcomes and indexes to provide a better understanding of the extent to which passive exposure to aerosols produced by use of e-cigarette impacts exhaled NO and exhaled breath condensate metabolites.
Within the TackSHS project (H2020 project grant agreement No 681040), we will conduct a clinical research study, aiming at: i) to measure respiratory health effects when exposed to secondhand smoke (SHS) in patients with asthma and Chronic Obstructive Pulmonary Disease (COPD); ii) to investigate exposure levels to SHS in smoking areas provided by bars, casinos, bingo halls, etc. The study will involve 60 patients (volunteers) in three European countries: Czech Republic, Ireland, and Spain, recruiting 20 patients in each participating country (10 COPD and 10 asthma patients).
Within the TackSHS project (H2020 project grant agreement No 681040), we will conduct a European cross-sectional study, aiming at i) estimating prevalence and investigating determinants of smoking, e-cigarette use and exposure to SHS and to e-cigarette aerosol; ii) analyzing the attitudes, perceptions and behaviours of the adult European population towards policies to limit SHS exposure; iii) comparing selected smoking-related data between TackSHS and a previously conducted pan-European survey; iv) assessing mortality and morbidity from selected respiratory and cardiovascular diseases attributable to SHS exposure among adults and children in Europe; v) quantifying the economic burden associated to the exposure to SHS and e-cigarette aerosol in Europe. Overall, approximately 12,000 individuals aged 15 years or over will be enrolled in 12 different European countries (BG, DE, ES, FR, GR, IE, IT, LV, PL, PT, RO, UK). Surveys will be representative of the country-specific population in terms of sex, age, and socio-economic characteristics.
The purpose of this randomized controlled trial is to develop and test the efficacy of a multilevel, multimodal intervention designed to modify maternal smoking behavior to reduce children's exposure to secondhand tobacco smoke (primary outcome) and promote their smoking cessation (secondary outcome). Low-income mothers who smoke will be enrolled. Mothers will be recruited from the supplemental nutrition program, Women, Infants and Children (WIC) clinics. All mothers visiting WIC clinics will receive a clinic-level intervention, which consists of nutrition counselors following an "ask, advise, and refer" protocol to identify if their children are exposed to secondhand tobacco smoke, advise mothers who smoke about the harms of such exposure and the benefits of reducing exposure, and referring mothers to the trial. Screened eligible mothers will be consented and randomized to an attention control condition focused on nutrition (CTL) or to an experimental (EXP) multimodal behavioral intervention that integrates telebased counseling to promote the reduction of child secondhand smoke exposure (SHSE) and maternal smoking with an adjunct smoking cessation mobile app and nicotine replacement therapy use. The investigators will test the primary hypothesis that relative to children in the CTL condition, those in the EXP condition will have lower exposure SHSE as measured by mothers' reports and child cotinine levels. The investigators will also test the secondary hypothesis that relative to mothers in the CTL condition, those in the EXP condition will have higher bioverified 7-day point prevalence quit rates. In addition, the study will: (a) evaluate if specific psychosocial and behavioral factors-- social support, urge coping skills, self-efficacy, and SHSe protective behaviors--mediate the effects of the EXP intervention on outcomes and (b) explore whether other residential smokers, level of nicotine dependence, depressive/anxious symptoms, weight concerns, intervention dosage, and pregnancy status predict outcomes and moderate treatment effects.
This project proposes to evaluate the effectiveness of training Head Start staff to discuss tobacco use, shs reduction and cessation in their existing encounters with parents in reducing tobacco use and exposure. Understanding the facilitators and barriers to integrating the intervention into the Head Start system will support future efforts to address tobacco use and exposure in families with small children.
Children who are hospitalized are especially vulnerable to the effects of tobacco use and dependence among their caregivers, and they are more likely to be exposed than children who are not hospitalized. Hospitalization is an important teachable moment for health care providers to intervene with tobacco dependent parents, and help them reduce their child's exposure, potentially improving outcomes after hospitalization, and their future health. Understanding the best way to approach and intervene with these families will provide the investigator with the necessary information to create a sustainable intervention that can be disseminated to hospitals across the country that provide pediatric care, and to ultimately make a significant improvement in the health of children.
The long-term goal is to improve the quality of life of children and their parents who smoke tobacco by facilitating parental smoking cessation in a way that is easy to administer yet effective. We aim to accomplish this goal by administering an interactive computer-based program that will facilitate motivation and readiness to engage in smoking cessation by providing personalized feedback about the financial and health effects of the parent's smoking. We will compare the changes in motivation and readiness to quit smoking after the parent has taken the computer-based program and compare them to the changes in motivation and readiness to quit in parents who receive only information about the Oklahoma Tobacco Helpline. We will also measure salivary cotinine levels in both parents and children, to objectively measure changes in smoking habits and secondhand smoke exposure. Our hypothesis is that our computer-based program will cause a greater increase in motivation and confidence to quit smoking in the group that receives the customized feedback than the group that receives only information about the Tobacco Helpline. We also predict that both parent and child cotinine levels will show a greater decrease in the group randomized to receive personalized feedback.
The study's primary aim is to test the hypothesis that an intervention integrating pediatric clinic-level quality improvement with home-level behavioral counseling (CQI+BC) will result in greater reductions in child cotinine (a biomarker of secondhand smoke exposure) and reported cigarettes exposed/day than a clinic-level quality improvement plus attention control intervention (CQI+A). A secondary aim is to test the hypothesis that relative to CQI+A, CQI+BC will result in higher cotinine-verified, 7-day point prevalence quit rate among parents.
