项目摘要

DESCRIPTION (provided by applicant): Regular physical activity contributes to the health and quality of life of older adults, but unfortunately only 20% of men and 25% of women aged 65 years and greater meet the minimal national guidelines for physical activity. Older Latinos have higher rates of diseases that are most likely to benefit from physical activity, but have disproportionately high rates of sedentary lifestyle. To address this major public health problem, the proposed study seeks to implement and evaluate a multifaceted intervention to raise and sustain walking levels among older Latinos. Previously, this multidisciplinary team of investigators designed and pilot-tested a structured intervention to raise walking levels by raising older adults' expectations for aging. They now propose to evaluate the efficacy and sustainability of this intervention in a randomized clinical trial. The team plans to enroll 600 sedentary older Latinos recruited from community-based senior centers in the greater Los Angeles region. The specific aims of the proposed study are to test the effect of the intervention on: 1) the primary outcome: change in steps per week measured by digital pedometer from baseline to 1, 12, and 24-month follow-up; 2) self-reported physical activity level and intervening constructs (including expectations regarding aging and self-efficacy expectations for physical activity); 3) secondary outcomes including psychosocial health constructs, physical performance measures and clinical health outcomes. The core of the intervention consists of a series of 4 weekly 1-hour group discussion sessions that utilize attribution retraining techniques from the field of motivational psychology in combination with behavioral strategies based in social cognitive theory. Discussion sessions will be conducted at senior centers and led by a bilingual health educator; each session will be followed by a 1-hour exercise class aimed at increasing strength, flexibility and endurance. During the discussion sessions, the health educator will administer a structured culturally-tailored curriculum in which participants are taught to raise their expectations for physical activity with aging, and not to attribute being sedentary to "old age." The 4 weekly sessions will be followed by monthly sessions for 11 months, and sessions every 2 months for he following 12 months (total intervention duration = 24 months). Participants will be randomized to 1 of 2 arms: 1) intervention arm) receiving the discussion session and the exercise class; 2) (control arm) receiving just the exercise class with the same frequency and duration as the intervention group. The goal of this project is to demonstrate success of a feasible intervention that raises and sustains walking levels among older Latinos.

描述（由申请人提供）：定期体育锻炼有助于老年人的健康和生活质量，但不幸的是，只有20％的男性和25％的65岁妇女和更大的女性满足了最小的国家体育活动准则。较旧的拉丁美洲人具有较高的疾病率，最有可能从体育锻炼中受益，但久坐的生活方式的比例高。为了解决这个重大的公共卫生问题，拟议的研究旨在实施和评估多方面的干预措施，以提高和维持较老的拉丁美洲人的步行水平。以前，这个多学科研究人员团队设计并试点测试了结构化干预措施，以提高老年人对衰老的期望，提高步行水平。他们现在建议在一项随机临床试验中评估这种干预措施的功效和可持续性。该团队计划从大洛杉矶地区的社区高级中心招募600个久坐的久坐的拉丁美洲人。拟议研究的具体目的是测试干预措施对：1）主要结果：数字计步器从基线到1、12和24个月的随访的每周台阶变化； 2）自我报告的体育活动水平和中间结构（包括对体育锻炼的衰老和自我效能感的期望）； 3）次要结果，包括社会心理健康结构，身体表现措施和临床健康结果。干预的核心包括一系列每周4小时的小组讨论会议，这些会议利用了从激励心理学领域的归因研究，并结合基于社会认知理论的行为策略。讨论会议将在高级中心举行，并由双语健康教育者领导；每次会议都将进行1小时的运动课，旨在提高力量，灵活性和耐力。在讨论会议期间，健康教育者将管理一个结构化的文化规划课程，其中教会参与者提高对体育锻炼的期望，而不是将久违的人归因于“老年”。每周的4个会议将在11个月内进行11个月的每月课程，并且在12个月后每2个月进行一次（总干预持续时间= 24个月）。参与者将被随机分为2个武器中的1个：1）干预组）接受讨论会和练习课； 2）（控制臂）仅接受与干预组相同频率和持续时间的运动类。该项目的目的是展示可行的干预措施的成功，该干预措施提高了拉丁美洲裔较旧的拉丁美洲人的步行水平。
