Detailed Description

Successfully transferring the findings of expensive and tightly controlled lifestyle intervention programmes to the primary care setting is necessary if such knowledge is to be used for disease prevention at the population level. Therefore, our objective was to evaluate the efficacy of a lifestyle intervention programe in the primary health care setting, targeted at patients with moderate- to high-risk of cardiovascular disease according to cardiovascular risk factor levels, physical activity and quality of life ratings.

Randomised controlled trial with follow-up at 3, 12, 24 and 36 months, carried out in a primary health care centre in Northern Sweden. A total of 151 middle-aged men and women, with hypertension, dyslipidemia, type 2 diabetes or obesity were enrolled. The subjects were randomised to an intervention (n = 75) or control group (n = 76). 120 subjects completed the three-year follow-up. The intervention was based on the protocols used in the Finnish Diabetes Prevention study (DPS) and the U.S Diabetes Prevention Program
