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.
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.
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.
Members of primary care, adult patient population will increase their duration of physical activity in response to physician advice to exercise.
尽管久坐这种普遍的生活方式被认为是冠状动脉疾病及其他病症的重要风险因素，但对于初级保健环境中预防策略的有效性却知之甚少。本研究探讨家庭医生提供简短运动建议的影响。
在为期2个月的基线期，询问前来就诊的18岁及以上患者的运动习惯和态度，以及他们的医生是否讨论过运动。在接下来的2个月实验阶段，收集相同的数据，并且一半的医生接受培训以提供简短的运动建议。所有患者被随访1个月。运动时长和频率的变化是主要的结局指标。
在基线期，相当一部分患者得到了运动建议。在实验阶段，对照组患者也是如此，尽管接受培训的医生给出建议的频率几乎是对照组医生的两倍。接受建议的患者与未接受建议的患者相比，运动时长显著增加，但频率未显著增加。患者态度对运动建议有反应。
初级保健中的成年患者群体将根据医生的运动建议增加其身体活动时长。
