ABSTRACT This paper evaluates the 10-year outcomes of a Northern Sweden community intervention program for the prevention of cardiovascular disease (CVD), with special reference to the social patterning of risk development.
Using a quasi-experimental design, trends in risk factors and predicted mortality in an intervention area (Norsjö municipality) are compared with those in a reference area (Northern Sweden region) by repeated independent cross-sectional surveys.
There were significant differences in changes in total cholesterol level and systolic blood pressure between the intervention and reference populations. The predicted coronary heart disease mortality (based on the North Karelia risk equation). after adjustment for age and education, was reduced by 36% in the intervention area and by 1% in the reference area.
We conclude that a long-term community-based CVD prevention program which combines population and individual strategies can substantially promote a health shift in CVD risk in a high risk rural population. When evaluated for different social strata, we found no signs of an increasing health gap between socially privileged and less privileged groups. Socially less-privileged groups benefited the most from the present prevention program.

    ABSTRACT: Complementary strategies to shift risk factor population distributions and target high-risk individuals are required to reduce the burden of type 2 diabetes and cardiovascular disease (CVD). To examine secular changes in glucose and CVD risk factors over 20 years during an individual and population-based CVD prevention program in Västerbotten County, Sweden. Population-based health promotion intervention was conducted and annual invitation for individuals turning 40, 50, and 60 years to attend a health assessment, including an oral glucose tolerance test, biochemical measures, and a questionnaire. Data were collected between 1991 and 2010, analyzed in 2012 and available for 120,929 individuals. Linear regression modeling examined age-adjusted differences in CVD risk factor means over time. Data were direct-age-standardized to compare disease prevalence. Between 1991-1995 and 2006-2010, mean age-adjusted cholesterol (men=-0.53, 95% CI=-0.55, -0.50 mmol/L; women=-0.48, 95% CI=-0.50, -0.45 mmol/L) and systolic blood pressure declined (men=-3.06, 95% CI=-3.43, -2.70 mm Hg; women=-5.27, 95% CI=-5.64, -4.90 mm Hg), with corresponding decreases in the age-standardized prevalence of hypertension and hyperlipidemia. Mean age-adjusted 2-hour plasma glucose (men=0.19, 95% CI=0.15, 0.23 mmol/L; women=0.08, 95% CI=0.04, 0.11 mmol/L) and BMI increased (men=1.12, 95% CI=1.04, 1.21; women=0.65, 95% CI=0.55, 0.75), with increases in the age-standardized prevalence of diabetes and obesity. These data demonstrate the potential of combined individual- and population-based approaches to CVD risk factor control and highlight the need for additional strategies addressing hyperglycemia and obesity.

    ABSTRACT: High blood pressure (BP) is the greatest risk of ill health and an early death worldwide. It is a key factor in the development of atherosclerosis, the main cause of vascular and cerebrovascular diseases, and is causally linked to kidney failure and dementia. Healthy lifestyle choices coupled with effective, population-based prevention strategies, early detection, and optimal treatment and control of high BP can substantially reduce the burden of vascular and cerebrovascular diseases. Considering the projected increases in the risk factors responsible for these conditions, it is imperative that effective population-based prevention strategies are developed, evaluated, and scaled-up. Extensive and rigourous evidence supports the promotion of healthy lifestyle choices to maintain low BP and prevent associated chronic diseases. Community-based programs are the prime tool for implementing a population strategy of prevention. Their aim is to shift the distribution of risk factors to lower levels across entire populations. Despite their great potential and more than a 4-decade history, it remains unclear to what extent such programs can be effectively implemented, scaled-up and sustained. We provide a broad overview of community-based programs implemented to address cardiovascular disease risk factors, focus on the recent Canadian experience in this area, and highlight the main challenges and opportunities currently associated with them. Recent Canadian initiatives have shown encouraging results, some of them focusing on high-risk subgroups. These initiatives demonstrate feasibility and benefits of implementing community-based programs for the prevention and management of cardiovascular disease in Canada.
