Identifying the energy gap: Magnitude and determinants of 5-year weight gain in midage women

Objective: The aims of this study were to estimate average yearly weight gain in midage women and to identify the determinants of weight gain and gaining weight at double the average rate. Research Methods and Procedures: The study sample comprised 8071 participants (45 to 55 years old) in the Australian Longitudinal Study on Women's Health who completed mailed surveys in 1996, 1998, and 2001. Results: On average, the women gained almost 0.5 kg per year [average 2.42 kg (95% confidence interval, 2.29 to 2.54) over 5 years]. In multivariate analyses, variables associated with energy balance (physical activity, sitting time, and energy intake), as well as quitting smoking, menopause/hysterectomy, and baseline BMI category were significantly associated with weight gain, but other behavioral and demographic characteristics were not. After adjustment for all of the other biological and behavioral variables, the odds of gaining weight at about twice the average rate (> 5 kg over 5 years) were highest for women who quit smoking (odds ratio = 2.94; 95% confidence interval, 2.17, 3.96). There were also independent relationships between the odds of gaining > 5 kg and lower levels of habitual physical activity, more time spent sitting, energy intake (but only in women with BMI > 25 at baseline), menopause transition, and hysterectomy. Discussion: The average weight gain equates with an energy imbalance of only about 10 kcal or 40 kJ per day, which suggests that small sustained changes in the modifiable behavioral variables could prevent further weight gain.

Genetic analyses of DSM-IV nicotine withdrawal in adult twins

Background. We examined whether there are genetic influences on nicotine withdrawal. and whether there are genetic factors specific to nicotine withdrawal, after controlling for factors responsible for risk of progression beyond experimentation with cigarettes and for quantity smoked (average number of cigarettes per day at peak lifetime use). Method. Epidemiologic and genetic analyses were conducted using telephone diagnostic interview data from Young adult Australian twins reporting any cigarette use (3026 women. 2553 men: mean age 30 years). Results. Genetic analysis of the eight symptoms of DSM-IV nicotine withdrawal suggests heritability is intermediate for most symptoms (26-43%). and Similar in men and women. The exceptions were depressed mood upon withdrawal. which had stronger additive genetic influences in men (53%) compared to worrien (29%). and decreased heart rate. which had low heritability (9%). Although prevalence rates were substantlally lower for DSM-IV nicotine withdrawal syndrome (15-9%), which requires impairment. than for the DSM-IV nicotine dependence withdrawal criterion (43.6%), heritability was similar for both measures: as high as 47%. Genetic modeling of smoking more than 1 or 2 cigarettes lifetime ('progression'). qualtity smoked and nicotine withdrawal found significant genetic overlap across all three components of nicotine use/dependence (genetic correlations = 0.53-0.76). Controlling for factors associated with risk of cigarette smoking beyond experimentation and quantity smoked, evidence for genetic influences specific to nicotine withdrawal (up to 23% of total variance) remained. Conclusions. Our results suggest that at least some individuals become 'hooked' or progress in the smoking habit, in part, because of it vulnerability to nicotine withdrawal.

Comparative cost-effectiveness of policy instruments for reducing the global burden of alcohol, tobacco and illicit drug use

Alcohol, tobacco and illicit drug use together pose a formidable challenge to international public health. Building on earlier estimates of the demonstrated burden of alcohol, tobacco and illicit drug use at the global level, this review aims to consider the comparative cost-effectiveness of evidence-based interventions for reducing the global burden of disease from these three risk factors. Although the number of published cost-effectiveness studies in the addictions field is now extensive ( reviewed briefly here) there are a series of practical problems in using them for sector-wide decision making, including methodological heterogeneity, differences in analytical reference point and the specificity of findings to a particular context. In response to these limitations, a more generalised form of cost-effectiveness analysis (CEA) is proposed, which enables like-with-like comparisons of the relative efficiency of preventive or individual-based strategies to be made, not only within but also across diseases or their risk factors. The application of generalised CEA to a range of personal and non-personal interventions for reducing the burden of addictive substances is described. While such a development avoids many of the obstacles that have plagued earlier attempts and in so doing opens up new opportunities to address important policy questions, there remain a number of caveats to population-level analysis of this kind, particularly when conducted at the global level. These issues are the subject of the final section of this review.

The Genetic Landscape of Renal Complications in Type 1 Diabetes

Diabetes is the leading cause of end stage renal disease. Despite evidence for a substantial heritability of diabetic kidney disease, efforts to identify genetic susceptibility variants have had limited success. We extended previous efforts in three dimensions, examining a more comprehensive set of genetic variants in larger numbers of subjects with type 1 diabetes characterized for a wider range of cross-sectional diabetic kidney disease phenotypes. In 2,843 subjects, we estimated that the heritability of diabetic kidney disease was 35% ( p=6x10-3 ). Genome-wide association analysis and replication in 12,540 individuals identified no single variants reaching stringent levels of significance and, despite excellent power, provided little independent confirmation of previously published associated variants. Whole exome sequencing in 997 subjects failed to identify any large-effect coding alleles of lower frequency influencing the risk of diabetic kidney disease. However, sets of alleles increasing body mass index ( p=2.2×10-5) and the risk of type 2 diabetes (p=6.1x10-4 ) were associated with the risk of diabetic kidney disease. We also found genome-wide genetic correlation between diabetic kidney disease and failure at smoking cessation ( p=1.1×10-4 ). Pathway analysis implicated ascorbate and aldarate metabolism ( p=9×10-6), and pentose and glucuronate interconversions ( p=3×10-6) in pathogenesis of diabetic kidney disease. These data provide further evidence for the role of genetic factors influencing diabetic kidney disease in those with type 1 diabetes and highlight some key pathways that may be responsible. Altogether these results reveal important biology behind the major cause of kidney disease.  

Exercise and Lifestyle Therapy Improves Weight Maintenance in Young People With Psychosis: A Service Evaluation

INTRODUCTION Young people with psychosis typically have higher rates of premature cardiovascular disease and metabolic disorders compared to non-psychotic peers. This has been primarily due to a sedentary lifestyle, poor diet composition, misuse of harmful substances and higher rates of obesity and smoking. When prescribed obesogenic antipsychotic medication, a weight gain of >12 kg within 2 years is typical. PURPOSE: To examine the benefits of a 12 wk exercise and lifestyle intervention entitled ‘Supporting Health and Promoting Exercise’ (SHAPE) for young people recently diagnosed with psychosis. METHODS Participants (n=26; 8 females; mean age 27.7 ± 5.1) engaged in weekly 45’ education sessions on healthy lifestyle behaviors, including: managing anxiety and depression, mindfulness and relaxation training, substance misuse, smoking cessation, healthy eating and nutritional advice, dental and sexual health care. This was followed by a 45’ exercise session including activities such as circuit and resistance training, yoga, and badminton, led by qualified exercise instructors. Anthropometric data were measured at baseline, 12 wk and 12 month post-intervention. Lifestyle behaviors and clinical measurements, including resting heart rate, blood pressure, total cholesterol, triglycerides, HbA1c and prolactin, were assessed at baseline and 12 months post-intervention as part of their routine clinical care plan. Significant differences over time were assessed using Paired Sample t-tests. RESULTS SHAPE participants (n=26) presented with first episode psychosis (n=11), schizophrenia (n=11), bipolar disorder (n=2), at risk mental state (n=1), and persistent delusion disorder (n=1) of which 52% were prescribed highly obesogenic antipsychotic medications (Clozapine and Olanzepine). Mean baseline data suggests participants were at an increased health risk due to elevated values in mean BMI (70% were overweight or obese), waist circumference, resting heart rate, and triglycerides (see Table 1 & 2). Over 50% reported smoking daily and 85% had elevated resting blood pressure (>120/80 mm Hg). At 12 wk post-intervention, no changes were observed in mean BMI or waist circumference (see Table 1); 19 participants either maintained (mean 0.5 kg: range ± 2 kg) or decreased (mean -5.7 kg: range 2-7 kg) weight; 7 participants increased weight (mean 4.9 kg: range 2.0-9.6 kg). At 12 month post-intervention (n=16), no change was evident in mean BMI, waist circumference, or any other clinical variable (see Table 2). Positive impacts on lifestyle behaviors included 7 participants eating ~400g of fruit/vegetables daily, 2 ceased substance use, 2 ceased alcohol use, 4 ceased smoking and 5 were less sedentary. CONCLUSION At the start of the programme, participants were already at an increased risk for cardiometabolic disorders. Findings suggest that SHAPE supported young people with psychosis to: -attenuate their physical health risk following a 12 wk exercise and lifestyle intervention which were sustained at 12 months follow up. -make positive lifestyle behavior changes leading to sustained improvements in weight maintenance and physical health.

Identifying health inequalities in individuals with major mental illness (MMI) using routine data

Abstract and Summary of Thesis: Background: Individuals with Major Mental Illness (such as schizophrenia and bipolar disorder) experience increased rates of physical health comorbidity compared to the general population. They also experience inequalities in access to certain aspects of healthcare. This ultimately leads to premature mortality. Studies detailing patterns of physical health comorbidity are limited by their definitions of comorbidity, single disease approach to comorbidity and by the study of heterogeneous groups. To date the investigation of possible sources of healthcare inequalities experienced by individuals with Major Mental Illness (MMI) is relatively limited. Moreover studies detailing the extent of premature mortality experienced by individuals with MMI vary both in terms of the measure of premature mortality reported and age of the cohort investigated, limiting their generalisability to the wider population. Therefore local and national data can be used to describe patterns of physical health comorbidity, investigate possible reasons for health inequalities and describe mortality rates. These findings will extend existing work in this area. Aims and Objectives: To review the relevant literature regarding: patterns of physical health comorbidity, evidence for inequalities in physical healthcare and evidence for premature mortality for individuals with MMI. To examine the rates of physical health comorbidity in a large primary care database and to assess for evidence for inequalities in access to healthcare using both routine primary care prescribing data and incentivised national Quality and Outcome Framework (QOF) data. Finally to examine the rates of premature mortality in a local context with a particular focus on cause of death across the lifespan and effect of International Classification of Disease Version 10 (ICD 10) diagnosis and socioeconomic status on rates and cause of death. Methods: A narrative review of the literature surrounding patterns of physical health comorbidity, the evidence for inequalities in physical healthcare and premature mortality in MMI was undertaken. Rates of physical health comorbidity and multimorbidity in schizophrenia and bipolar disorder were examined using a large primary care dataset (Scottish Programme for Improving Clinical Effectiveness in Primary Care (SPICE)). Possible inequalities in access to healthcare were investigated by comparing patterns of prescribing in individuals with MMI and comorbid physical health conditions with prescribing rates in individuals with physical health conditions without MMI using SPICE data. Potential inequalities in access to health promotion advice (in the form of smoking cessation) and prescribing of Nicotine Replacement Therapy (NRT) were also investigated using SPICE data. Possible inequalities in access to incentivised primary healthcare were investigated using National Quality and Outcome Framework (QOF) data. Finally a pre-existing case register (Glasgow Psychosis Clinical Information System (PsyCIS)) was linked to Scottish Mortality data (available from the Scottish Government Website) to investigate rates and primary cause of death in individuals with MMI. Rate and primary cause of death were compared to the local population and impact of age, socioeconomic status and ICD 10 diagnosis (schizophrenia vs. bipolar disorder) were investigated. Results: Analysis of the SPICE data found that sixteen out of the thirty two common physical comorbidities assessed, occurred significantly more frequently in individuals with schizophrenia. In individuals with bipolar disorder fourteen occurred more frequently. The most prevalent chronic physical health conditions in individuals with schizophrenia and bipolar disorder were: viral hepatitis (Odds Ratios (OR) 3.99 95% Confidence Interval (CI) 2.82-5.64 and OR 5.90 95% CI 3.16-11.03 respectively), constipation (OR 3.24 95% CI 3.01-3.49 and OR 2.84 95% CI 2.47-3.26 respectively) and Parkinson’s disease (OR 3.07 95% CI 2.43-3.89 and OR 2.52 95% CI 1.60-3.97 respectively). Both groups had significantly increased rates of multimorbidity compared to controls: in the schizophrenia group OR for two comorbidities was 1.37 95% CI 1.29-1.45 and in the bipolar disorder group OR was 1.34 95% CI 1.20-1.49. In the studies investigating inequalities in access to healthcare there was evidence of: under-recording of cardiovascular-related conditions for example in individuals with schizophrenia: OR for Atrial Fibrillation (AF) was 0.62 95% CI 0.52 - 0.73, for hypertension 0.71 95% CI 0.67 - 0.76, for Coronary Heart Disease (CHD) 0.76 95% CI 0.69 - 0.83 and for peripheral vascular disease (PVD) 0.83 95% CI 0.72 - 0.97. Similarly in individuals with bipolar disorder OR for AF was 0.56 95% CI 0.41-0.78, for hypertension 0.69 95% CI 0.62 - 0.77 and for CHD 0.77 95% CI 0.66 - 0.91. There was also evidence of less intensive prescribing for individuals with schizophrenia and bipolar disorder who had comorbid hypertension and CHD compared to individuals with hypertension and CHD who did not have schizophrenia or bipolar disorder. Rate of prescribing of statins for individuals with schizophrenia and CHD occurred significantly less frequently than in individuals with CHD without MMI (OR 0.67 95% CI 0.56-0.80). Rates of prescribing of 2 or more anti-hypertensives were lower in individuals with CHD and schizophrenia and CHD and bipolar disorder compared to individuals with CHD without MMI (OR 0.66 95% CI 0.56-0.78 and OR 0.55 95% CI 0.46-0.67, respectively). Smoking was more common in individuals with MMI compared to individuals without MMI (OR 2.53 95% CI 2.44-2.63) and was particularly increased in men (OR 2.83 95% CI 2.68-2.98). Rates of ex-smoking and non-smoking were lower in individuals with MMI (OR 0.79 95% CI 0.75-0.83 and OR 0.50 95% CI 0.48-0.52 respectively). However recorded rates of smoking cessation advice in smokers with MMI were significantly lower than the recorded rates of smoking cessation advice in smokers with diabetes (88.7% vs. 98.0%, p<0.001), smokers with CHD (88.9% vs. 98.7%, p<0.001) and smokers with hypertension (88.3% vs. 98.5%, p<0.001) without MMI. The odds ratio of NRT prescription was also significantly lower in smokers with MMI without diabetes compared to smokers with diabetes without MMI (OR 0.75 95% CI 0.69-0.81). Similar findings were found for smokers with MMI without CHD compared to smokers with CHD without MMI (OR 0.34 95% CI 0.31-0.38) and smokers with MMI without hypertension compared to smokers with hypertension without MMI (OR 0.71 95% CI 0.66-0.76). At a national level, payment and population achievement rates for the recording of body mass index (BMI) in MMI was significantly lower than the payment and population achievement rates for BMI recording in diabetes throughout the whole of the UK combined: payment rate 92.7% (Inter Quartile Range (IQR) 89.3-95.8 vs. 95.5% IQR 93.3-97.2, p<0.001 and population achievement rate 84.0% IQR 76.3-90.0 vs. 92.5% IQR 89.7-94.9, p<0.001 and for each country individually: for example in Scotland payment rate was 94.0% IQR 91.4-97.2 vs. 96.3% IQR 94.3-97.8, p<0.001. Exception rate was significantly higher for the recording of BMI in MMI than the exception rate for BMI recording in diabetes for the UK combined: 7.4% IQR 3.3-15.9 vs. 2.3% IQR 0.9-4.7, p<0.001 and for each country individually. For example in Scotland exception rate in MMI was 11.8% IQR 5.4-19.3 compared to 3.5% IQR 1.9-6.1 in diabetes. Similar findings were found for Blood Pressure (BP) recording: across the whole of the UK payment and population achievement rates for BP recording in MMI were also significantly reduced compared to payment and population achievement rates for the recording of BP in chronic kidney disease (CKD): payment rate: 94.1% IQR 90.9-97.1 vs.97.8% IQR 96.3-98.9 and p<0.001 and population achievement rate 87.0% IQR 81.3-91.7 vs. 97.1% IQR 95.5-98.4, p<0.001. Exception rates again were significantly higher for the recording of BP in MMI compared to CKD (6.4% IQR 3.0-13.1 vs. 0.3% IQR 0.0-1.0, p<0.001). There was also evidence of differences in rates of recording of BMI and BP in MMI across the UK. BMI and BP recording in MMI were significantly lower in Scotland compared to England (BMI:-1.5% 99% CI -2.7 to -0.3%, p<0.001 and BP: -1.8% 99% CI -2.7 to -0.9%, p<0.001). While rates of BMI and BP recording in diabetes and CKD were similar in Scotland compared to England (BMI: -0.5 99% CI -1.0 to 0.05, p=0.004 and BP: 0.02 99% CI -0.2 to 0.3, p=0.797). Data from the PsyCIS cohort showed an increase in Standardised Mortality Ratios (SMR) across the lifespan for individuals with MMI compared to the local Glasgow and wider Scottish populations (Glasgow SMR 1.8 95% CI 1.6-2.0 and Scotland SMR 2.7 95% CI 2.4-3.1). Increasing socioeconomic deprivation was associated with an increased overall rate of death in MMI (350.3 deaths/10,000 population/5 years in the least deprived quintile compared to 794.6 deaths/10,000 population/5 years in the most deprived quintile). No significant difference in rate of death for individuals with schizophrenia compared with bipolar disorder was reported (6.3% vs. 4.9%, p=0.086), but primary cause of death varied: with higher rates of suicide in individuals with bipolar disorder (22.4% vs. 11.7%, p=0.04). Discussion: Local and national datasets can be used for epidemiological study to inform local practice and complement existing national and international studies. While the strengths of this thesis include the large data sets used and therefore their likely representativeness to the wider population, some limitations largely associated with using secondary data sources are acknowledged. While this thesis has confirmed evidence of increased physical health comorbidity and multimorbidity in individuals with MMI, it is likely that these findings represent a significant under reporting and likely under recognition of physical health comorbidity in this population. This is likely due to a combination of patient, health professional and healthcare system factors and requires further investigation. Moreover, evidence of inequality in access to healthcare in terms of: physical health promotion (namely smoking cessation advice), recording of physical health indices (BMI and BP), prescribing of medications for the treatment of physical illness and prescribing of NRT has been found at a national level. While significant premature mortality in individuals with MMI within a Scottish setting has been confirmed, more work is required to further detail and investigate the impact of socioeconomic deprivation on cause and rate of death in this population. It is clear that further education and training is required for all healthcare staff to improve the recognition, diagnosis and treatment of physical health problems in this population with the aim of addressing the significant premature mortality that is seen. Conclusions: Future work lies in the challenge of designing strategies to reduce health inequalities and narrow the gap in premature mortality reported in individuals with MMI. Models of care that allow a much more integrated approach to diagnosing, monitoring and treating both the physical and mental health of individuals with MMI, particularly in areas of social and economic deprivation may be helpful. Strategies to engage this “hard to reach” population also need to be developed. While greater integration of psychiatric services with primary care and with specialist medical services is clearly vital the evidence on how best to achieve this is limited. While the National Health Service (NHS) is currently undergoing major reform, attention needs to be paid to designing better ways to improve the current disconnect between primary and secondary care. This should then help to improve physical, psychological and social outcomes for individuals with MMI.

South Carolina COPD Strategic Plan

Chronic obstructive pulmonary disease is the third leading cause of death in South Carolina and affects approximately 15 percent of the adult population. Although tobacco cessation and avoidance are slowly advancing in South Carolina, 20 percent of COPD occurs in non-smokers, and this percentage will likely increase in the coming years. Therefore, a strategic plan must include other initiatives in addition to smoking cessation. This document was developed by a multidisciplinary group of health care providers, public health practitioners, and patients, as such a combined approach is imperative to target this disease.

Nichtmedikamentöse Sekundärprävention der koronaren Herzkrankheit (KHK)

Hintergrund: Die koronare Herzkrankheit (KHK) ist eine häufige und potenziell tödliche Erkrankung mit einer Lebenszeitprävalenz von über 20%. Allein in Deutschland wird die Zahl der durch die ischämische Herzerkrankung und des akuten Myokardinfarkts jährlich verursachten Todesfälle auf etwa 140.000 geschätzt. Ein Zusammenhang eng mit dem Lebensstil verbundener Risikofaktoren mit Auftreten und Prognose der KHK ist nachgewiesen. Durch Maßnahmen der nichtmedikamentösen Sekundärprävention wird versucht, diese Risikofaktoren positiv zu verändern sowie die KHK im Gegensatz zu palliativen interventionellen Therapiestrategien kausal zu behandeln. Zur Wirksamkeit der nichtmedikamentösen sekundärpräventiven Maßnahmen liegt eine ganze Reihe von Einzelstudien und -untersuchungen vor, eine systematische Analyse, die die Evidenz aller hauptsächlich angewandten Sekundärpräventionsstrategien zusammenfasst, fehlt unseres Wissens nach bislang jedoch. Auch eine Auswertung vorhandener Studien zur Kosten-Effektivität der Maßnahmen ist hierbei zu integieren. Fragestellung: Ziel dieses HTA-Berichts (HTA=Health Technology Assessment) ist die Erstellung einer umfassenden Übersicht der aktuellen Literatur zu nichtmedikamentösen Sekundärpräventionsmaßnahmen in der Behandlung der KHK, um diese Maßnahmen und deren Komponenten bezüglich ihrer medizinischen Wirksamkeit sowie Wirtschaftlichkeit zu beurteilen. Weiterhin sollen die ethischen, sozialen und rechtlichen Aspekte der nichtmedikamentösen Sekundärprävention und die Übertragbarkeit der Ergebnisse auf den deutschen Versorgungsalltag untersucht werden. Methodik: Relevante Publikationen werden über eine strukturierte und hochsensitive Datenbankrecherche sowie mittels Handrecherche identifiziert. Die Literaturrecherche wird in vier Einzelsuchen zu medizinischen, gesundheitsökonomischen, ethischen und juristischen Themen am 18.09.2008 durchgeführt und erstreckt sich über die vergangenen fünf Jahre. Die methodische Qualität der Publikationen wird von jeweils zwei unabhängigen Gutachtern unter Beachtung von Kriterien der evidenzbasierten Medizin (EbM) systematisch geprüft. Ergebnisse: Von insgesamt 9.074 Treffern erfüllen 43 medizinische Publikationen die Selektionskriterien, mit einem Nachbeobachtungszeitraum zwischen zwölf und 120 Monaten. Insgesamt ist die Studienqualität zufriedenstellend, allerdings berichtet nur ca. die Hälfte der Studien differenziert die Gesamtmortalität, während die übrigen Studien andere Outcomemaße verwenden. Die Wirksamkeit einzelner Sekundärpräventionsmaßnahmen stellt sich als sehr heterogen dar. Insgesamt kann langfristig eine Reduktion der kardialen sowie der Gesamtmortalität und der Häufigkeit kardialer Ereignisse sowie eine Erhöhung der Lebensqualität beobachtet werden. Vor allem für trainingsbasierte und multimodale Interventionen ist eine effektive Reduktion der Mortalität zu beobachten, während psychosoziale Interventionen besonders in Bezug auf eine Erhöhung der Lebensqualität effektiv zu sein scheinen. Für die ökonomischen Auswertungen werden 26 Publikationen identifiziert, die von ihrer Themenstellung und Studienart dem hier betrachteten Kontext zugeordnet werden können. Insgesamt kann festgestellt werden, dass sich die Studienlage zur multimodalen Rehabilitation sowohl bezüglich ihrer Menge als auch Qualität der Analysen besser darstellt, als dies für Evaluationen von Einzelmaßnahmen beobachtet werden kann. Die internationale Literatur bestätigt den multimodalen Ansätzen dabei zwar ein gutes Verhältnis von Kosten und Effektivität, untersucht jedoch nahezu ausschließlich ambulante oder häuslichbasierte Maßnahmen. Die Auswertung der Studien, die einzelne sich mit präventiven Maßnahmen in Hinblick auf ihre Kosten-Effektivität beschäftigen, ergibt lediglich positive Tendenzen für Interventionen der Raucherentwöhnung und des körperlichen Trainings. Im Hinblick auf psychosoziale Maßnahmen sowie auch die Ernährungsumstellung können aufgrund der unzureichenden Studienlage jedoch keine Aussagen über die Kosten-Effektivität getroffen werden. Insgesamt werden im Rahmen der Betrachtung sozialer Aspekte der nichtmedikamentösen Sekundärprävention elf Publikationen einbezogen. Die relativ neuen Studien bestätigen, dass Patienten mit niedrigem sozioökonomischen Status insgesamt schlechtere Ausgangsbedingungen und demnach einen spezifischen Bedarf an rehabilitativer Unterstützung haben. Gleichzeitig sind sich die Forscher jedoch uneinig, ob gerade diese Patientengruppe relativ häufiger oder seltener an den Rehabilitationsmaßnahmen teilnimmt. Bezüglich der Barrieren, die Patienten von der Teilnahme an den präventiven Maßnahmen abhalten, werden psychologische Faktoren, physische Einschränkungen aber auch gesellschaftliche und systemisch-orientierte Einflüsse genannt. Diskussion: Nichtmedikamentöse Sekundärpräventionsmaßnahmen sind sicher und in der Lage eine Reduktion der Mortalität sowie der Häufigkeit kardialer Ereignisse zu erzielen sowie die Lebensqualität zu erhöhen. Da nur wenige der methodisch verlässlichen Studien Teilnehmer über einen längeren Zeitraum von mindestens 60 Monaten nachverfolgen, müssen Aussagen über die Nachhaltigkeit als limitiert angesehen werden. Verlässliche Angaben in Bezug auf relevante Patientensubgruppen lassen sich nur sehr eingeschränkt machen ebenso wie im Hinblick auf die vergleichende Beurteilung verschiedener Maßnahmen der Sekundärprävention, da diese von eingeschlossenen Studien nur unzureichend erforscht wurden. Zukünftige methodisch verlässliche Studien sind notwendig, um diese Fragestellungen zu untersuchen und zu beantworten. Bezogen auf die Kosten-Effektivität nichtmedikamentöser sekundärpräventiver Maßnahmen kann aus den internationalen Studien eine insgesamt positive Aussage zusammengefasst werden. Einschränkungen dieser resultieren jedoch zum einen aus den Besonderheiten des deutschen Systems der stationären Rehabilitationsangebote, zum anderen aus den qualitativ mangelhaften Evaluationen der Einzelmaßnahmen. Studien mit dem Ziel der Bewertung der Kosten-Effektivität stationärer Rehabilitationsangebote sind ebenso erforderlich wie auch qualitativ hochwertige Untersuchungen einzeln erbrachter Präventionsmaßnahmen. Aus sozialer Perspektive sollte insbesondere untersucht werden, welche Patientengruppe aus welchen Gründen von einer Teilnahme an Rehabilitations- bzw. präventiven Maßnahmen absieht und wie diesen Argumenten begegnet werden könnte. Schlussfolgerung: Nichtmedikamentöse sekundärpräventive Maßnahmen sind in der Lage eine Reduktion der Mortalität und der Häufigkeit kardialer Ereignisse zu erzielen sowie die Lebensqualität zu erhöhen. Eine Stärkung des Stellenwerts nichtmedikamentöser Maßnahmen der Sekundärprävention erscheint vor diesem Hintergrund notwendig. Auch kann für einige Interventionen ein angemessenes Verhältnis von Effektivität und Kosten angenommen werden. Es besteht allerdings nach wie vor erheblicher Forschungsbedarf bezüglich der Wirksamkeitsbeurteilung nichtmedikamentöser Maßnahmen der Sekundärprävention in wichtigen Patientensubgruppen und der Effizienz zahlreicher angebotener Programme. Darüber hinaus ist weitere Forschung notwendig, um die Nachhaltigkeit der Maßnahmen und Gründe für die Nichtinanspruchnahme detailliert zu untersuchen. Vor allem gilt es jedoch den Versorgungsalltag in Deutschland, wie er sich für Ärzte, Patienten und weitere Akteure des Gesundheitswesens darstellt, zu untersuchen und den heutigen Stellenwert nichtmedikamentöser Maßnahmen aufzuzeigen.

ESR/ERS white paper on lung cancer screening

Lung cancer is the most frequently fatal cancer, with poor survival once the disease is advanced. Annual low-dose computed tomography has shown a survival benefit in screening individuals at high risk for lung cancer. Based on the available evidence, the European Society of Radiology and the European Respiratory Society recommend lung cancer screening in comprehensive, quality-assured, longitudinal programmes within a clinical trial or in routine clinical practice at certified multidisciplinary medical centres. Minimum requirements include: standardised operating procedures for low-dose image acquisition, computer-assisted nodule evaluation, and positive screening results and their management; inclusion/exclusion criteria; expectation management; and smoking cessation programmes. Further refinements are recommended to increase quality, outcome and cost-effectiveness of lung cancer screening: inclusion of risk models, reduction of effective radiation dose, computer-assisted volumetric measurements and assessment of comorbidities (chronic obstructive pulmonary disease and vascular calcification). All these requirements should be adjusted to the regional infrastructure and healthcare system, in order to exactly define eligibility using a risk model, nodule management and a quality assurance plan. The establishment of a central registry, including a biobank and an image bank, and preferably on a European level, is strongly encouraged. Key points: • Lung cancer screening using low dose computed tomography reduces mortality. • Leading US medical societies recommend large scale screening for high-risk individuals. • There are no lung cancer screening recommendations or reimbursed screening programmes in Europe as of yet. • The European Society of Radiology and the European Respiratory Society recommend lung cancer screening within a clinical trial or in routine clinical practice at certified multidisciplinary medical centres. • High risk, eligible individuals should be enrolled in comprehensive, quality-controlled longitudinal programmes.

Equity-focused health impact assessment of Portuguese tobacco control legislation

The World Health Organization recommend the Equity-Focused Health Impact Assessment (HIA) as a means to assess the impact of social and economic policies on the health of populations, and acknowledges their contribution to health inequality. We describe the application of the Equity-focusedImpact Assessment methodology on the Portuguese law on Smoking Prevention and Tobacco Control (Law No. 37/2007). A rapid assessment was carried out to issue recommendations which could be incorporated into the law during a revision in 2014. Quantitative (consumption and health status indicators; equity analysis) and qualitative (Focus Group) approaches were taken to evaluate the impact of the law and formulate recommendations. Young people, men and women of low socioeconomic status, and pregnant women were identified as requiring specific and appropriate interventions to prevent smoking and support smoking cessation.

Porque é que pais e mães fumadores fumam dentro de casa?

Este estudo pretende identificar os fatores que influenciam os pais fumadores a fumar ou não dentro de casa. Realizaram-se, por telefone, entrevistas semiestruturadas a 10 pais e 10 mães, de crianças do 4º ano de escolaridade, fumadores que fumavam em casa, e a 10 pais e 10 mães fumadores, mas que não o faziam em casa. A análise de conteúdo mostrou que a preocupação com a saúde dos filhos e o mau cheiro foram os principais motivos mencionados pelos progenitores para não fumarem no domicílio. A comodidade e as condições meteorológicas foram as principais razões dos progenitores para fumarem no domicílio. Os pais fumadores que não fumam em casa parecem ter maior consciência dos riscos de fumar no domicílio para a saúde dos filhos, enquanto que os pais que fumam no domicílio fazem-no essencialmente por comodismo e desconhecimento aparente das consequências negativas desse comportamento. Deverá ser prioridade da educação para a saúde melhorar o conhecimento dos pais sobre as consequências da exposição ao fumo passivo. É indispensável que os profissionais de saúde das várias especialidades se envolvam no tratamento da dependência tabágica, promovendo a cessação tabágica dos pais, sendo esta a via mais segura para garantir casas livres de fumo.

Objetivo: El propósito del estudio fue describir estadísticamente las etapas de cambio comportamental frente al consumo de sustancias psicoactivas –SPA– (alcohol, tabaco y drogas ilegales) en escolares entre 9 y 17 años de Bogotá- Colombia, pertenecientes al estudio FUPRECOL. Método: Se trata de un estudio descriptivo y transversal en 6.965 niños y adolescentes entre 9 y 17 años, pertenecientes a 24 instituciones educativas oficiales de Bogotá - Colombia. La medición de los procesos de cambio propuestos por el Modelo Transteórico (MTT), aplicados al consumo de drogas, tabaco y alcohol se aplicaron de manera auto-diligenciada mediante un cuestionario estructurado. Resultados: De la muestra evaluada, el 58,4% fueron mujeres con un promedio de edad 12,74 ± 2.38 años. En la población en general, frente al consumo de drogas, el 6% de los escolares se encontraban en etapa de pre-contemplación, 44 % en contemplación; 30% en preparación/acción, 20% en mantenimiento. Con relación al consumo de alcohol, el 5% de los niños y adolescentes se encontraban en etapa de pre-contemplación, 36 % en contemplación; 12% en preparación/acción, 46% en mantenimiento. Frente al tabaco, el 4% de los niños y adolescentes se encontraban en etapa de pre-contemplación, 33 % en contemplación; 12% en preparación/acción, 51% en mantenimiento. Conclusiones: En los escolares evaluados, un importante porcentaje se ubica en la etapa de mantenimiento frente a la intención de consumo de tabaco y alcohol. Frente al consumo de drogas ilegales los niños y adolescentes están en la etapa de contemplación. Se requieren esfuerzos mayores para fomentar programas preventivos que enseñen sobre el riesgo del abuso/dependencia de este tipo de sustancias psicoactiva sobre la salud; dándole prioridad en las agendas y políticas públicas dentro del ámbito escolar.
