OBJECTIVE: To test the short and long-term effectiveness of a four week residential program for primary health care patients to control obesity and related risk factors for cardio-vascular disease (CVD), especially blood pressure (BP).

DESIGN: Prospective clinical study, with follow up after 1 and 5 y.

SETTING: Vindeln Patient Education Centre, Vindeln, and Department of Social Medicine, University of Umea, Sweden.

SUBJECTS: Approximately 2500 individuals, with two or more of the traditional risk factors for CVD, participated in the program. This report describes a subsample of 100 consecutive patients, 52+/-9 y, 53 men, with obesity and/or high BP. Intervention: Four week residential program with lectures and group discussions as well as practical sessions in smaller groups (meal preparations, physical exercise, etc). The patients were followed-up medically in their home area.

OUTCOME MEASURES: Weight and blood pressure.

RESULTS: Dramatic reductions of weight and, especially, of blood pressure (BP) occurred during the residential weeks, and the reductions were pronounced also after 1 y. After 5 y, the total mean weight among men with initial BMI > or = 30 kg/m2 was still 5 kg lower, and diastolic and systolic BP among those with hypertension was 15 and 20 mm Hg lower, respectively, than before the program.

CONCLUSIONS: The full-time participation in the residential program and the enrollment and commitment of the patients may explain the clinical outcome. A level of predisposition greater than that required of most weight- and BP-control programs was confirmed and a great preventive or therapeutic potential was indicated. The study illustrates an effective application of the Precede-Proceed model of health promotion planning.
