Mass media interventions for smoking cessation in adults.

BACKGROUND: Mass media tobacco control campaigns can reach large numbers of people. Much of the literature is focused on the effects of tobacco control advertising on young people, but there are also a number of evaluations of campaigns targeting adult smokers, which show mixed results. Campaigns may be local, regional or national, and may be combined with other components of a comprehensive tobacco control policy. OBJECTIVES: To assess the effectiveness of mass media interventions in reducing smoking among adults. SEARCH METHODS: The Cochrane Tobacco Addiction Group search strategy was combined with additional searches for any studies that referred to tobacco/smoking cessation, mass media and adults. We also searched the Cochrane Central Register of Controlled Trials (CENTRAL) and a number of electronic databases. The last search was carried out in November 2016. SELECTION CRITERIA: Controlled trials allocating communities, regions or states to intervention or control conditions; interrupted time series.Adults, 25 years or older, who regularly smoke cigarettes. Studies which cover all adults as defined in studies were included.Mass media are defined here as channels of communication such as television, radio, newspapers, billboards, posters, leaflets or booklets intended to reach large numbers of people, and which are not dependent on person-to-person contact. The purpose of the mass media campaign must be primarily to encourage smokers to quit. They could be carried out alone or in conjunction with tobacco control programmes.The primary outcome was change in smoking behaviour. This could be reported as changes in prevalence, changes in cigarette consumption, quit rates, or odds of being a smoker. DATA COLLECTION AND ANALYSIS: Two authors independently assessed all studies for inclusion criteria and for study quality (MB, LS, RTM). One author (MB) extracted data, and a second author (LS) checked them.Results were not pooled due to heterogeneity of the included studies and are presented narratively and in table form. MAIN RESULTS: Eleven campaigns met the inclusion criteria for this review. Studies differed in design, settings, duration, content and intensity of intervention, length of follow-up, methods of evaluation and also in definitions and measures of smoking behaviour used. Among seven campaigns reporting smoking prevalence, significant decreases were observed in the California and Massachusetts statewide tobacco control campaigns compared with the rest of the USA. Some positive effects on prevalence in the whole population or in the subgroups were observed in three of the remaining seven studies. Three large-scale campaigns of the seven presenting results for tobacco consumption found statistically significant decreases. Among the eight studies presenting abstinence or quit rates, four showed some positive effect, although in one of them the effect was measured for quitting and cutting down combined. Among the three that did not show significant decreases, one demonstrated a significant intervention effect on smokers and ex-smokers combined. AUTHORS' CONCLUSIONS: There is evidence that comprehensive tobacco control programmes which include mass media campaigns can be effective in changing smoking behaviour in adults, but the evidence comes from a heterogeneous group of studies of variable methodological quality. One state-wide tobacco control programme (Massachusetts) showed positive results up to eight years after the campaign. Another (California) showed positive results during the period of adequate funding and implementation and in final evaluation since the beginning of the programme. Six of nine studies carried out in communities or regions showed some positive effects on smoking behaviour and at least one significant change in smoking prevalence (Sydney). The intensity and duration of mass media campaigns may influence effectiveness, but length of follow-up and concurrent secular trends and events can make this difficult to quantify. No consistent relationship was observed between campaign effectiveness and age, education, ethnicity or gender.

Management and treatment goals in Polish patients with type 2 diabetes of short duration: results of the ARETAEUS2-Grupa study.

INTRODUCTION:  In 2011, the Diabetes Poland updated its recommended goals in diabetes treatment, including hemoglobin A1c (HbA1c) and blood pressure (BP) levels. Adherence to the updated guidelines has not been systematically assessed so far. OBJECTIVES:  The aim of the study was to assess which methods are most commonly used in the treatment of recently diagnosed type 2 diabetes and to what extent the new criteria for diabetes control are met in these patients. PATIENTS AND METHODS:  The ARETAEUS2­Grupa study was a cross­sectional questionnaire­based study conducted in Poland in 2012 (April-June). It involved 1636 patients of any age and sex, with type 2 diabetes diagnosed within the previous 2 years, recruited by randomly selected physicians. RESULTS:  Of all patients, 37.5% met the goal of an HbA1c level of ≤6.5% (recommended in type 2 diabetes of short duration), while 62% met the goal of an HbA1c level of ≤7% (general recommendation). Only 6.7% of the patients met all 3 goals (HbA1c ≤6.5%, BP <140/90 mmHg, and low­density lipoprotein cholesterol <100 mg/dl or <70 mg/dl in coronary heart disease), 29.7% met 2 goals, 36.8% met only 1 goal, while 26.7% did not meet any of the treatment goals. With the use of the HbA1c level recommended for the overall population, the proportions of patients meeting 3, 2, and 1 goals increased to 11%, 34.5%, and 35.5%, respectively, while the percentage of the patients not meeting any goals decreased to 18%. Metformin in monotherapy or in combination was the most commonly used drug in the study population (80%).  CONCLUSIONS:  The majority of the patients with type 2 diabetes of short duration did not meet any of the treatment goals as recommended in the current practice guidelines. When the treatment goals were used for the overall population (HbA1c ≤7%), a slightly higher, but still unsatisfactory, proportion of the patients met all the treatment goals. Metformin alone or in combination was the most commonly used drug in the study population.

Efficacy of pharmacological methods used for treating tobacco dependence: meta-analysis.

OBJECTIVES: The present study summarizes available evidence describing efficacy of pharmacological methods used in smoking cessation and presents the results of new meta-analyses examining their 12-month efficacy. This work represents part of a larger program examining the efficacy and cost-effectiveness of different methods used in smoking cessation. PATIENTS AND METHODS: The first part of the study included systematic review of literature to identify methods used in smoking cessation with efficacy confirmed on the basis of existing reliable systematic reviews or meta-analyses. In the second stage of the process, for the interventions judged both available in Poland (on the basis of literature search and interviews with healthcare providers) and efficacious, we have performed new meta-analyses designed to establish their 12-month efficacy (continuous or prolonged abstinence). RESULTS: We found that the most comprehensive and up-to-date data were available in Cochrane reviews. Meta-analyses of randomised controlled trials performed in the second part of the work showed that adding pharmacological methods of smoking cessation available in Poland, such as nicotine replacement therapy (NRT) and bupropion, to nonpharmacological methods increased the probability of smoking cessation and smoking abstinence for > or =12 months by over 1.5 to about 3 times and the number needed to treat to have one patient stop smoking ranged from 8 to 21. CONCLUSIONS: We confirmed that pharmacological methods of smoking cessation available in Poland, such as NRT and bupropion, added to nonpharmacological methods increase the probability of smoking abstinence and we quantified 12-month effects of these interventions.
