DESCRIPTION (provided by applicant): This new investigator application is for the PA-10-070, Academic Research Enhancement Award (R15) and it is aligned with the mission of NINR to develop community-based approaches to promote health and prevent disease. Over 98% of older women do not meet national guidelines for physical activity (PA). There is clear evidence that a physically active lifestyle reduces the human and economic cost of heart disease in a dose-response relationship; but current efforts to increase long-term PA in older women are inadequate. The aims of this proposed research are to: 1) determine the feasibility of using an individually tailored motivational counseling intervention method to promote lifestyle physical activity (LPA) in older sedentary women; 2) examine intervention effects by comparing baseline to outcome measures at 3 and 6 months in treatment and information/attention comparison groups; and 3) explore stage of behavior change and self- efficacy and their relationship to LPA, along with functional health. This will be a single blinded randomized controlled study of sedentary women aged 60 years and older. We will replace "structured aerobic exercise" with lifestyle physical activity (LPA), i.e., self-selected activities performed daily in a purposeful manner to meet the national PA guidelines. A total of 120 older women who are ambulatory and cognitively intact will be recruited from a senior health clinic and randomized to receive either the motivational LPA intervention or information/attention. Women will be assessed at baseline, 3 and 6 months. The theoretically based behavioral intervention is derived from the Transtheoretical Model and other evidence-based physical activity research. We will use a Motivational Interviewing counseling technique delivered by a social worker to individually tailor the LPA intervention to participant preferences, taking into consideration their functional ability and need for information, readiness to change, and self-efficacy. Outcomes of the LPA intervention sessions will include tailored goals and an LPA plan. Intervention participants will also receive the newly developed NIA "Exercise & You" LPA informational booklet with companion DVD as well as motivational coaching via telephone calls, tapering in frequency for 6 months. The control group will receive the NIA LPA booklet with DVD and attention telephone calls. We will assess changes from baseline in LPA (primary outcome), readiness to change, and self-efficacy and function (secondary outcomes) and examine the associations between primary and secondary outcomes in both groups. The allied disciplines of Nursing, Gerontology, Social Work, and Medicine will collaborate to promote PA and cardiovascular health of older women. Undergraduate and graduate student research assistants will contribute to this project. This research has the potential to increase PA of sedentary older women and reduce CHD risks. If we could increase physical activity in our rapidly growing older population -even modestly, we could make a significant impact to the health of our nation. PUBLIC HEALTH RELEVANCE: Making physical activity an integral part of daily life is imperative to the health and well-being of our nation's older adults. However, no intervention strategy to encourage daily physical activity for older adults, especially older women, has been effective. This feasibility study will test a multi-tailored motivational intervention to increase sual lifestyle physical activity of older sedentary women to reduce their coronary heart disease risks.

描述（由申请人提供）：这一新的研究者申请是为PA-10-070，学术研究增强奖（R15），它是与NINR的使命，以开发基于社区的方法，以促进健康和预防疾病。超过98%的老年女性不符合国家体育活动指南（PA）。有明确的证据表明，身体活跃的生活方式在剂量反应关系中降低了心脏病的人力和经济成本;但目前在老年妇女中增加长期PA的努力是不够的。本研究的目的是：1）确定使用个性化的动机咨询干预方法来促进老年久坐妇女的生活方式体力活动（LPA）的可行性; 2）通过比较治疗组和信息/注意力对照组的基线与3个月和6个月的结果测量来检查干预效果;（3）探讨行为改变阶段、自我效能与LPA的关系，以及沿着功能健康。 这是一项在60岁及以上久坐女性中进行的单盲随机对照研究。我们将以生活方式体育活动（LPA）取代“有组织的有氧运动”，即，每天有目的地进行自选活动，以符合国家PA指南。将从高级健康诊所招募120名门诊和认知完整的老年妇女，并随机接受激励性LPA干预或信息/关注。将在基线、3个月和6个月时对女性进行评估。基于理论的行为干预是从跨理论模型和其他基于证据的身体活动研究中衍生出来的。我们将使用由社会工作者提供的动机访谈咨询技术，根据参与者的偏好，考虑他们的功能能力，个性化定制LPA干预 以及对信息的需求、对改变的准备和自我效能。LPA干预会议的结果将包括量身定制的目标和LPA计划。干预参与者还将收到新开发的NIA“运动与你”LPA信息小册子与配套DVD，以及通过电话进行激励辅导，频率逐渐减少，持续6个月。对照组将收到NIA LPA小册子和DVD以及关注电话。我们将评估LPA（主要结局）、改变准备、自我效能和功能（次要结局）较基线的变化，并检查两组主要结局和次要结局之间的相关性。护理，老年学，社会工作和医学的联合学科将合作促进老年妇女的PA和心血管健康。本科生和研究生研究助理将有助于这个项目。这项研究有可能增加久坐的老年妇女的PA并降低CHD风险。如果我们能够在迅速增长的老年人口中增加体育活动--即使是适度的，我们也可以对我们国家的健康产生重大影响。 公共卫生相关性：使体育活动成为日常生活的一个组成部分，对我国老年人的健康和福祉至关重要。然而，没有干预策略，以鼓励老年人，特别是老年妇女的日常体力活动，一直是有效的。这项可行性研究将测试一种多量身定制的动机干预，以增加久坐的老年妇女的日常生活方式的身体活动，以减少他们的冠心病风险。
