The effect of physician advice on exercise behavior.

BACKGROUND

Although sedentariness, a prevalent lifestyle, is recognized as a significant risk factor for coronary artery disease and other conditions, little is known about the effectiveness of prevention strategies in the primary care setting. This study examines the impact of brief, exercise advice-giving by family physicians.

METHODS

During a 2-month baseline period, patients visiting their family physician and who were age 18 or older were queried about their exercise habits and attitudes and whether their physician had discussed exercise. During the following 2-month experimental phase, the same data were gathered, and half the physicians were trained to give brief exercise advice. All patients were followed for 1 month. Changes in exercise duration and frequency were the primary outcome measures.

RESULTS

During baseline, a sizable portion of patients were given exercise advice. This was true also of control group patients during the experimental phase, although trained physicians gave advice almost twice as often. A comparison of the patients receiving advice with those not receiving advice revealed significant increases in exercise duration, but not frequency. Patient attitudes were responsive to exercise advice.

CONCLUSION

Members of primary care, adult patient population will increase their duration of physical activity in response to physician advice to exercise.
