[BDSP. Notice produite par INIST WR0x86k7. Diffusion soumise à autorisation]. Objective-To examine the effects of a GP exercise referral programme on modifiable coronary heart disease risk factors. Design-Randomised controlled trial. A battery of validated measures were carried out at 0,8,16,26, and 37 weeks. Setting-Two community health centres and a leisure centre in Hailsham, East Sussex. Subjects-389 patients (smokers, hypertensive or overweight) were selected from medical records, screened for contraindications to exercise and 345 were invited into the study. Of 142 patients randomly allocated, 40 (41%) completed the study in the exercise group and 31 (69%) in the control group. Sixty (35%) invited smokers (48% of non-smokers), 71 (38%) invited hypertensive patients (45% of non-hypertensive patients), and 107 (45%) overweight patients (33% of non-overweight patients) were randomised. Of those randomised, 27 (45%) smokers, 52 (48%) overweight, and 43 (61%) hypertensive patients completed the study. Intervention-The exercise group was offered 20, half price sessions over 10 weeks at a leisure centre. Patients engaged in moderate and vigorous aerobic type activity on various exercise machines, in a semi-supervised, informal environment. Results-87% of those referred used the prescription and 28% (high adherers) (45% of obese patients) did at least 15 sessions. The exercise group reduced sum of skinfolds by 8.1% (2.9 to 13.3,95% confidence intervals) more than the control group, up to 16 weeks after baseline. (...)
