Regional variability in the prevalence of cerebral white matter lesions: an MRI study in 9 European countries (CASCADE).

White matter lesions (WML) on MRI of the brain are common in both demented and nondemented older persons. They may be due to ischemic events and are associated with cognitive and physical impairments. It is not known whether the prevalence of these WML in the general population differs across European countries in a pattern similar to that seen for coronary heart disease. Here we report the prevalence of WML in 1,805 men and women drawn from population-based samples of 65- to 75-year-olds in ten European cohorts. Data were collected using standardized methods as a part of the multicenter study CASCADE (Cardiovascular Determinants of Dementia). Centers were grouped by region: south (Italy, Spain, France), north (Netherlands, UK, Sweden), and central (Austria, Germany, Poland). In this 10-year age stratum, 92% of the sample had some lesions, and the prevalence increased with age. The prevalence of WML was highest in the southern region, even after adjusting for differences in demographic and selected cardiovascular risk factors. Brain aging leading to disabilities will increase in the future. As a means of hypothesis generation and for health planning, further research on the geographic distribution of WML may lead to the identification of new risk factors for these lesions.

Gender and regional differences in perceived job stress across Europe.

BACKGROUND: Over the last 20 years stress at work has been found to be predictive of several conditions such as coronary heart disease, high blood pressure and non-specific sick leave. The Karasek demand/control/strain concept has been the most widely used in prospective epidemiological studies. OBJECTIVES: To describe distribution in Karasek's demand/control (DC) dimensions as well as prevalence of strain in samples from different parts of Europe grouped into three regions (South, Middle, Sweden), adjusting for occupation. To describe gender differences in Karasek's DC dimensions along with strain prevalence and assess the regional stability of those differences in different occupational groups. DESIGN: The Job stress, Absenteeism and Coronary heart disease in Europe (JACE) study, a Concerted Action (Biomed I) of the European Union, is a multicentre prospective cohort epidemiological study: 38,019 subjects at work aged 35-59 years were surveyed at baseline. Standardised techniques were used for occupation coding (International Standardised Classification of Occupations) and for the DC model (Karasek scale): five items for the psychological demand and nine items for the control or decision latitude dimensions, respectively. RESULTS: A total of 34,972 subjects had a complete data set. There were important regional differences in the Karasek scales and in prevalence of strain even after adjustment for occupational class. Mean demand and control were higher in the Swedish centres when compared to two centres in Milano and Barcelona (Southern region) and values observed in four centres (Ghent, Brussels, Lille and Hoofddorp) in Middle Europe were closer to those observed in the Southern cities than to those obtained in the Swedish cities. Clerks (ISCO 4) and, more specifically, office clerks (ISCO 41) exhibited the smallest regional variation. In a multivariate model, the factor 'region' explained a small fraction of total variance. In the two Southern centres as well as in the four Middle European centres, men perceived marginally less job-demand as compared to women whereas the reverse was observed in the two Swedish centres. Differences were larger for control: men appeared to perceive more control at work than did women. In a multivariate model, gender explained a small fraction whereas occupational level explained a large fraction of the variance. CONCLUSIONS: In this standardised multicentre European study Karasek's DC model showed large gender and occupational differences whereas geographic region explained a small fraction of the total DC variance, notwithstanding large differences in labour market and working conditions as pointed out by the European Commission as recently as 2000.

[Psychosocial factors in coronary heart disease -- scientific evidence and recommendations for clinical practice].

Psychosocial risk factors like low socio-economic status, lack of social support and social isolation, chronic work or family stress, as well as negative emotions, e. g. depression and hostility, contribute significantly to the development and adverse outcome of coronary heart disease (CHD). Negative effects of psychosocial risk factors are conveyed via behavioural pathways including unhealthy lifestyle, e. g. food choice, smoking, sedentary life, inadequate utilisation of medical resources, and psychobiological mechanisms like disturbed autonomic and hormonal regulation: all these factors contribute to metabolic dysfunction and inflammatory and haemostatic processes, which are directly involved in the pathogenesis of CHD. Interventions to improve pychosocial factors are available and have demonstrated positive effects on risk factors and - at least in part - on CHD morbidity and mortality. The prevention of CHD should therefore include screening for psychosocial risk factors and adequate interventions. Recommedations for the screening of risk factors, behavioural change and further management of psychosocial risk factors in clinical practice are pointed out.

Risk factor management in diabetic and non-diabetic patients with coronary heart disease. Findings from the EUROASPIRE I AND II surveys.

AIMS/HYPOTHESIS: We examined risk factor management in diabetic and non-diabetic patients with CHD based on data from EUROASPIRE surveys. METHODS: Consecutive CHD patients aged 70 years or younger were interviewed and examined at least 6 months after hospitalisation for a revascularisation procedure or acute myocardial infarction or ischaemia. Of these patients, 3569 were from the EUROASPIRE I study, undertaken from 1995 to 1996 in nine countries, and 5556 were from the EUROASPIRE II study, conducted between 1999 and 2000 in 15 countries. RESULTS: In EUROASPIRE I and II 18% and 20% of CHD patients respectively had been previously diagnosed with diabetes. Fasting glucose screening raised the prevalence of diabetes in EUROASPIRE II to 28%. In EUROSPIRE II the prevalence of risk factors (known diabetic/non-diabetic) was: current smoking 17%/22 % ( p=0.25); obesity (BMI >/=30 kg/m(2)) 43%/29% ( p<0.001); raised blood pressure (>/=140/90 mm Hg) 57%/49% ( p<0.001); and elevated total cholesterol (>/=5.0 mmol/l) 55%/59% ( p<0.001). The proportion of users of cardiovascular medication was: antiplatelet drugs 83%/86% (NS); beta-blockers 62%/63% (NS); ACE inhibitors 49%/35% ( p<0.001); and lipid-lowering drugs 62%/61% (NS). A comparison of both studies showed that for diabetic and non-diabetic patients the prevalence of smoking had increased somewhat and that the prevalence of obesity had increased clearly. There was no improvement in blood pressure control, but cholesterol control had improved, mainly explained by the increased use of lipid-lowering drugs. CONCLUSIONS/INTERPRETATION: These European surveys show a high prevalence of adverse lifestyles and modifiable risk factors among diabetic and non-diabetic patients with CHD. The risk factor status was more adverse in diabetic patients.

Trends in obesity and energy supply in the WHO MONICA Project.

OBJECTIVE: To examine the relationship between secular trends in energy supply and body mass index (BMI) among several countries. DESIGN: Aggregate level analyses of annually reported country food data against anthropometric data collected in independent cross-sectional samples from 34 populations in 21 countries from the early 1980s to the mid-1990s. SUBJECTS: Population randomly selected participants aged 35-64 y. MEASUREMENTS: BMI data were obtained from the WHO MONICA Project. Food energy supply data were derived from the Food Balance Sheet of the Food and Agriculture Organization of the United Nations. RESULTS: Mean BMI as well as the prevalence of overweight (BMI > or =25 kg/m2) increased in virtually all Western European countries, Australia, the USA, and China. Decreasing trends in BMI were seen in Central and Eastern European countries. Increasing trends in total energy supply per capita were found in most high-income countries and China while decreasing trends existed in Eastern European countries. Between country differences in temporal trends of total energy supply per capita explained 41% of the variation of trends in mean BMI; the effect was similar upon the prevalence of overweight and obesity. Trends in percent of energy supply from total fat per capita had a slight effect on the trends in mean BMI (+7% increment in R2) when the total energy supply per capita was adjusted for, while energy supply from total sweeteners per capita had no additional effect. CONCLUSION: Increasing energy supply is closely associated with the increase of overweight and obesity in western countries. This emphasizes the importance of dietary issues when coping with the obesity epidemic.

Screening of family members of patients with premature coronary heart disease; results from the EUROASPIRE II family survey.

AIMS: To determine whether the Joint European Societies' recommendations that first degree blood relatives of patients with premature coronary heart disease (CHD) should be screened for coronary risk factors is being followed and, if so, how effectively these relatives are being managed. METHODS AND RESULTS: Using a postal questionnaire, 3322 relatives (siblings and children >/=18 years of age) of 1289 index patients in the EUROASPIRE II survey who had suffered from premature CHD (men under 55 years and women under 65 years) were asked whether screening for coronary risk factors had occurred and, if so, how they were being managed in terms of lifestyle advice and drug therapies. Overall, screening for coronary risk factors because of CHD in the family was only performed in 11.1% of siblings and 5.6% of children. However, prevalences of different cardiac risk factors were high both in relatives and offspring and a clear familial clustering could be documented. Less than 50% of siblings and 25% of children were given some general lifestyle advice regarding cardiac risk factors. Moreover, active interventions such as starting antihypertensive or lipid lowering drugs were rarely carried out, particularly in children of patients with premature CHD. CONCLUSIONS: European physicians rarely screen family members of patients with premature CHD for cardiac risk factors. General lifestyle style advice or active treatment for these risk factors are also rarely given. However, since these family members have a high prevalence and familial clustering of cardiac risk factors, they form an ideal target population for primary prevention of CHD in high-risk patients.

Estimation of ten-year risk of fatal cardiovascular disease in Europe: the SCORE project.

AIMS: The SCORE project was initiated to develop a risk scoring system for use in the clinical management of cardiovascular risk in European clinical practice. METHODS AND RESULTS: The project assembled a pool of datasets from 12 European cohort studies, mainly carried out in general population settings. There were 20,5178 persons (88,080 women and 11,7098 men) representing 2.7 million person years of follow-up. There were 7934 cardiovascular deaths, of which 5652 were deaths from coronary heart disease. Ten-year risk of fatal cardiovascular disease was calculated using a Weibull model in which age was used as a measure of exposure time to risk rather than as a risk factor. Separate estimation equations were calculated for coronary heart disease and for non-coronary cardiovascular disease. These were calculated for high-risk and low-risk regions of Europe. Two parallel estimation models were developed, one based on total cholesterol and the other on total cholesterol/HDL cholesterol ratio. The risk estimations are displayed graphically in simple risk charts. Predictive value of the risk charts was examined by applying them to persons aged 45-64; areas under ROC curves ranged from 0.71 to 0.84. CONCLUSIONS: The SCORE risk estimation system offers direct estimation of total fatal cardiovascular risk in a format suited to the constraints of clinical practice.

Evolution of all-causes and cardiovascular mortality in the age-group 75-84 years in Europe during the period 1970-1996; a comparison with worldwide changes.

BACKGROUND: In spite of the increase in longevity in the past century, studies of mortality patterns in elderly populations are scarce. We investigated cardiovascular and all-cause mortality patterns in age-group 75-84 years in Europe in the period 1970-1996. Methods Mortality data for the age-group 75-84 years were obtained from WHO and standardized according to the old European population standard. Tables were produced showing mortality rates per country around the year 1995 and trends were calculated over the period 1970-1996 using linear regression analysis. Results In both men and women aged 75-84 all-cause and cardiovascular mortality rates were higher in Central and Eastern Europe compared with Western Europe. For the last 3 available years, all-cause mortality rates differed by a factor 2/2.5 (men, women) when comparing the country with the highest with that of the lowest rate. For total cardiovascular mortality this factor was about 4/5 (men, women). During the period 1970-1996, all-cause and total cardiovascular mortality rates declined in most European countries. The decline in all causes of mortality was almost exclusively due to a decline in total cardiovascular disease mortality, especially stroke. Increases in total cardiovascular mortality were observed in some central European countries and Greece. CONCLUSION: Major changes, mainly a decline, occurred in all-cause and cardiovascular mortality in subjects aged 75-84 in Europe. Therefore a passive attitude to health problems in the elderly is not warranted.

[Trends in prevalence, awareness, treatment and control of arterial hypertension between 1986 and 1996: the MONICA-Catalonia study].

BACKGROUND: To describe temporal trends in blood pressure (BP) and in the prevalence, awareness, treatment and control of arterial hypertension(AH) between 1986-1996 in the MONICA-Catalonia study. SUBJECTS AND METHOD: Three cross-sectional health surveys in independent random samples of the general population aged 25-64, carried out in 1986-88,1990-92 and 1994-96 according to the WHO-MONICA study protocol.BP was measured twice with a random zero mercury sphygmomanometer. RESULTS: 2,571, 2,934 and 3,485 subjects were examined in each survey with response rates of 74, 67 and 72%, respectively. Age-adjusted mean of systolic BP (SBP) decreased 2 and 4 mmHg (p < 0.001)reaching 120 and 114 mmHg in 1994-96 in men and women, respectively. Diastolic BP (DBP) did not change in men (73-74 mmHg) nor in women(70-71 mmHg). Age-adjusted prevalence of AH (>= 160/95 and/or under pharmacological treatment) was 8% (men) and 10% (women)in 1994-96 and of AH (>= 140/90 and/or under pharmacological treatment) was 15% in both sexes. Awareness of hypertension (AH >= 140/90) increased from 67 to 76%. Treated hypertensives increased from 22 to 40% (men) and from 44 to 54% (women). The use of diuretics and betablockers decreased and ACE inhibitors increased. At the end of the period, 52% of hypertensives were controlled. SBP also decreased in normotensives but not DBP. CONCLUSIONS: Between 1986 and 1996, the prevalence of AH in Catalonia remained stable although awareness, treatment and control had substantially improved.SBP decreased but DBP remained stable.

Trends in coronary risk factors in the WHO MONICA project.

BACKGROUND: The World Health Organization (WHO) MONICA Project was established to determine how trends in event rates for coronary heart disease (CHD) and, optionally, stroke were related to trends in classic coronary risk factors. Risk factors were therefore monitored over ten years across 38 populations from 21 countries in four continents (overall period covered: 1979-1996). METHODS: A standard protocol was applied across participating centres, in at least two, and usually three, independent surveys conducted on random samples of the study populations, well separated within the 10-year study period. RESULTS: Smoking rates decreased in most male populations (35-64 years) but in females the majority showed increases. Systolic blood pressure showed decreasing trends in the majority of centres in both sexes. Mean levels of cholesterol generally showed downward trends, which, although the changes were small, had large effects on risk. There was a trend of increasing body mass index (BMI) with half the female populations and two-thirds of the male populations showing a significant increase. CONCLUSIONS: It is feasible to monitor the classic CHD risk factors in diverse populations through repeated surveys over a decade. In general, the risk factor trends are downwards in most populations but in particular, an increase in smoking in women in many populations and increasing BMI, especially in men, are worrying findings with significant public health implications.

Trends in cigarette smoking in 36 populations from the early 1980s to the mid-1990s: findings from the WHO MONICA Project.

OBJECTIVES: This report analyzes cigarette smoking over 10 years in populations in the World Health Organization (WHO) MONICA Project (to monitor trends and determinants of cardiovascular disease). METHODS: Over 300,000 randomly selected subjects aged 25 to 64 years participated in surveys conducted in geographically defined populations. RESULTS: For men, smoking prevalence decreased by more than 5% in 16 of the 36 study populations, remained static in most others, but increased in Beijing. Where prevalence decreased, this was largely due to higher proportions of never smokers in the younger age groups rather than to smokers quitting. Among women, smoking prevalence increased by more than 5% in 6 populations and decreased by more than 5% in 9 populations. For women, smoking tended to increase in populations with low prevalence and decrease in populations with higher prevalence; for men, the reverse pattern was observed. CONCLUSIONS: These data illustrate the evolution of the smoking epidemic in populations and provide the basis for targeted public health interventions to support the WHO priority for tobacco control.
