Associations between unemployment and cardiovascular risk factors varies with the unemployment rate: the Cardiovascular Risk Factor Study in Southern Sweden (CRISS).

AIMS: To investigate associations between CVD risk factors and socio-economic status (SES) in middle-age men during a period of economic changes. METHODS: Crossectional surveys at age 37, 40 and 43 in a birth cohort of men in Helsingborg, Sweden. All male residents born 1953-4 (n = 1460) were invited; participation rates were 68% (n = 991) at baseline. Of these enrolled, 78% (n = 770) were re-examined after three years and 71% (n = 702) again after six years follow-up. Main outcome measures were body mass index (BMI), S-cholesterol, HDL-cholesterol, systolic and diastolic blood pressure (SBP, DBP), smoking and leisure time physical activity (LTPA), education, employment, ethnicity. RESULTS: Baseline unemployment rate was low, n = 23 (2.4%), but three and six years later it had increased to 61 (8.2%) and 51 (7.5%) respectively. At baseline, BMI and S-cholesterol were significantly higher in unemployed than in employed men (deltaBMI 1.6 kg/m2, CI: 0.2; 2.9, delta S-cholesterol 0.6 mmol/L, CI: 0.1; 1.0), and in men with short versus long education (delta BMI 0.9 kg/m2, CI: 0.4; 1.4, delta S-cholesterol 0.2 mmol/L, CI: 0.03: 0.4), independent of other SES factors. Over the study period crossectional associations with employment status disappeared for BMI, but remained between short education and BMI. Short education was also associated with a significant increase in BMI (delta = 0.4 kg/m2, CI: 0.1; 0.7) during 6-year follow-up. CONCLUSIONS: This study shows that associations between unemployment and CVD risk factors were lost when unemployment rates increased. When the attributable risk of unemployment associated with CVD risk factors is estimated, it is vital to consider the general unemployment rates in society.

European guidelines on cardiovascular disease prevention in clinical practice: third joint task force of European and other societies on cardiovascular disease prevention in clinical practice (constituted by representatives of eight societies and by invited experts).

Guidelines aim to present all the relevant evidence on a particular issue in order to help physicians to weigh the benefits and risks of a particular diagnostic or therapeutic procedure. They should be helpful in everyday clinical decision-making. A great number of guidelines have been issued in recent years by different organisations--European Society of Cardiology (ESC), American Heart Association (AHA), American College of Cardiology (ACC), and other related societies. By means of links to web sites of National Societies several hundred guidelines are available. This profusion can put at stake the authority and validity of guidelines, which can only be guaranteed if they have been developed by an unquestionable decision-making process. This is one of the reasons why the ESC and others have issued recommendations for formulating and issuing guidelines. In spite of the fact that standards for issuing good quality guidelines are well defined, recent surveys of guidelines published in peer-reviewed journals between 1985 and 1998 have shown that methodological standards were not complied with in the vast majority of cases. It is therefore of great importance that guidelines and recommendations are presented in formats that are easily interpreted. Subsequently, their implementation programmes must also be well conducted. Attempts have been made to determine whether guidelines improve the quality of clinical practice and the utilisation of health resources. In addition, the legal implications of medical guidelines have been discussed and examined, resulting in position documents, which have been published by a specific task force. The ESC Committee for practice guidelines (CPG) supervises and coordinates the preparation of new guidelines and expert consensus documents produced by task forces, expert groups or consensus panels. The Committee is also responsible for the endorsement of these guidelines or statements.
