Filter by:The purpose of this study was to determine whether a media literacy education program taught be teacher to late elementary school students (grades 3-5) positively affected students' critical thinking skills and substance use-related health outcomes.
The investigators want to assess differences in lung function and bronchial inflammation of young smokers and non-smokers with (BMI > 30) and without obesity (BMI < 25)(4 patient groups). The aim of the study is to compare differences in lung function (VC, FEV1, VC/FEV1, metacholine challenge) and bronchial inflammation in relation with smoking history and levels of exhaled CO. For the latter the investigators will analyze the levels of IL-8, IL-6, TNF alpha and INF gamma and mRNA of LBP, TLR2 and TLR4 in sputum. Further, inflammatory markers e.g. low CRP and inflammatory cytokines levels in the blood will be investigated. The aim is to describe a early stage of chronic obstructive pulmonary disease caused by cigarette smoke in juvenile smokers, and the relationship between bronchial inflammation and obesity in adolescents.
This study shall determine whether or not proactive telephone support for smoking cessation delivered to quitline callers is more effective than standard 'reactive' provision and whether or not the offer of a voucher for a cost free supply of nicotine replacement therapy (NRT) has any additional impact on smoking cessation rates achieved by behavioural interventions.
The purpose of this research is to create an effective, disseminable, and exciting computer-based tobacco prevention program for 5th and 6th grade students. The goal of this school-based program is to decrease children's behavioral intentions and willingness to use tobacco, and to prevent or delay their initiation of tobacco use. We will augment the 5th grade program with a booster program in 6th grade, and evaluate the long-term efficacy of the entire tobacco prevention program by conducting a randomized controlled trial in elementary and middle schools.
Primary care physicians can play an important role in reducing tobacco smoking in the population. The general practice is a suitable setting for implementing proactive smoking interventions, because a large proportion of the population can be regularly reached in a favorable psychological state. Further, a trustful interpersonal relationship between the practitioners and their patients is supposed to increase the susceptibility to preventive measures. However, currently general practitioners are not capitalizing this advantage although evidence based treatments are available, which are effective and cost-effective. Outreach programs combining educational and practice-based measures have been found to be effective in engaging practitioners in screening and in giving advice. Computer expert-system and brief counseling interventions, which are based on the Transtheo-retical Model of behavior change (TTM), are promising approaches for the entire population of practitioners and smoking patients. For large scale implementation, data are needed about the degree of integration in every day routine clinical practice that could be achieved by implementing such interventions. Objectives: Evaluating different strategies for the implementation of proactive smoking interventions in general practices. Methods: In a randomized controlled trial, 150 randomly selected general practices of a defined German region will be included. The procedure comprises the implementation of 1) an on-site computer expert-system intervention, 2) a counseling intervention provided by the practitioner, or 3) the computer expert-system plus the counseling intervention. During an implementation phase of one month, two on site training sessions and support by phone will be provided. Routine use of the interventions will be monitored for the following 6 months. Main outcome measures are the number and rate of identified and treated smokers. A follow-up assessment will be realized 12 months after practice attendance to determine the smoking status of the treated smokers.
The study takes up two problems: 1) Little research exists about general population interventions for smokers not ready to quit within the foreseeable future. 2) There is little evidence for smoking reduction as a behavioural goal in interventions. Interventions based on the Transtheoretical Model of Behavior Change (TTM) using computer expert-system technology yield delayed and smaller effects in smokers in the precontemplation stage of change compared to smokers in more advanced stages of change. Reducing the number of cigarettes smoked per day is currently discussed as an intermediate goal for this subgroup. Epidemiological and clinical studies revealed that smokers are able to maintain a substantial reduction. No undermining effects with respect to smoking cessation have been found. However, there are no studies that test the efficacy of behavioural interventions for smoking reduction using population based recruitment. Objectives: Testing the efficacy of TTM based interventions for general population smokers not intending to quit smoking, i.e. a smoking-reduction and a smoking-cessation tailored intervention using computerized expert-system technology.
The purpose of this study is to determine if an integrated intervention addressing active smoking, environmental tobacco smoke exposure, depression and intimate partner violence, would improve pregnancy outcome among African American women.
