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）：有规律的体育活动有助于老年人的健康和生活质量，但不幸的是，65岁及以上的老年人中，只有20%的男性和25%的女性符合体育活动的最低国家指南。老年拉丁美洲人的疾病发病率较高，这些疾病最有可能从体育活动中受益，但久坐不动的生活方式的发病率却高得不成比例。为了解决这一重大的公共卫生问题，拟议的研究寻求实施和评估多方面的干预措施，以提高和维持拉丁美洲老年人的步行水平。
