Computerized Physical Activity Promotion in Primary Care

描述（由申请人提供）：鼓励将有效的体育活动促进干预措施纳入日常护理是国家卫生优先事项，以降低心血管疾病的发病率和死亡率。医生注意到一些障碍，辅导患者进行体育活动，包括缺乏时间，专业知识和组织支持。使用计算机收集数据以协助对患者进行咨询，并提供针对患者的材料以促进身体活动，是提高当前计算机技术和行为模型利用率的一种方式。本研究的具体目的是确定一个计算机程序的有效性，该程序可以创建1)针对个人的特定身体活动自助报告，以及2)针对患者的报告，以提示和指导医生的建议。本研究的主要目的是通过随机对照试验设计，确定在6个月的干预和随后6个月的随访后，患者和医生的身体活动电脑报告对身体活动的影响。医师实践将是随机化的单位。干预条件（IC）医生将收到

DESCRIPTION (provided by applicant): Encouraging the incorporation of effective physical activity promotion interventions into routine care is a national health priority to decrease the morbidity and mortality from cardiovascular disease. Physicians note several barriers to counseling patients to be physically active, including a lack of time, expertise, and organizational support. Using computers for collecting data to assist in counseling patients and to provide patient-specific materials to promote physical activity is a way of improving the utilization of current computer technologies and behavioral models. The specific aim of this study is to determine the efficacy of a computer program that creates 1) patient-specific physical activity self-help reports for individuals and 2) patient-specific reports to prompt and guide physician advice. The major objective of the proposed study is to determine via a randomized controlled trial design, the effects of the patient and physician physical activity computer reports on physical activity after a 6-month intervention and subsequent 6 months of follow-up. Physician practices will be the unit of randomization. Intervention condition (IC) physicians will receive training on physical activity counseling once and patient-specific computer-generated counseling prompts at all scheduled, non-acute visits of IC subjects. Enhanced Usual Care (EUC) condition physicians will receive training on general prevention guidelines but no tailored counseling prompts at patient visits. IC subjects will receive tailored print messages at baseline, 1, 3, and 6 months, in addition to a set of manuals targeted to their readiness to become physically active and standard prevention-oriented health education materials. EUC condition subjects will receive usual care physical activity advice and standard prevention-oriented health education materials. We hypothesize that at the end of 12 months, IC subjects will have a significantly greater increase in minutes of physical activity of at least moderate intensity (namely a 90 minute increase at 6 months and a 60 minute increase at 12 months) compared to EUC subjects.
