BAILA: Being Active, Increasing Latinos healthy Aging

描述（由申请人提供）：到2050年，老年拉丁美洲人预计将占老年人口的20%。身体活动（PA）可能影响身体和认知功能的健康结果的潜在下降，导致自我报告的功能限制和残疾。不幸的是，年龄在65-74岁的拉丁美洲人从事休闲时间PA的可能性比年龄较大的非拉丁美洲白人低46%，并且对少数民族的PA维护知之甚少。部分由于PA水平低，老年拉丁美洲人报告行走困难的可能性是非拉丁美洲白人的两倍，并且拉丁美洲人比非拉丁美洲白人早开始7年出现阿尔茨海默病症状。 参与PA有很大的潜力，以帮助老年人保持身体和认知功能，因为他们的年龄。舞蹈作为一种文化上适合这一弱势群体的PA形式，是一种在身体和认知上挑战个人的PA形式。到目前为止，为老年拉丁美洲人设计的PA计划仍然缺乏。BAILAMOS（c）是一个舞蹈项目，是根据居住在社区的老年拉丁美洲人的意见，并与一位有成就的拉丁舞教练合作开发的。一个单一的组，前后3个月的试点BAILAMOS（c）证明了实质性的计划可行性，效果大小表明更大的自我报告参与生活方式PA，沿着改善身体和认知功能。最初的3个月BAILAMOS（c）舞蹈计划已根据参与者和舞蹈教练的反馈进行了修改。 一项随机对照试验（RCT）在久坐不动，老年拉丁美洲人的残疾风险。参与者将被随机分配到BAILAMOS（c）条件或健康教育关注对照组。BAILAMOS（c）包括四种舞蹈风格，首先介绍最简单的风格（即，梅伦格）和最困难的风格最后（即，（1）提高自我效能。每一种风格都教了四周，每周两次，每节课一小时（共32节）。小组讨论如何增加生活方式PA包括在内。为了在正式方案结束后加强PA的维护，每个地点将培训2-3名“土著领导人”，教授为期4个月的BAILAMOS舞蹈（c）。控制条件的活动包括健康教育班进行西班牙语的双语/双文化健康教育工作者的伊利诺伊大学推广。 三年内将在九个地点招募332名老年拉丁美洲人。地点包括老年中心、社区中心和公园。每个研究中心将入组约40例受试者（治疗组20例，对照组20例）。本临床试验将测试BAILAMOS（c）计划对4个月时生活方式PA的影响，以及BAILAMOS（c）维持活动对8个月时生活方式PA维持的影响。将测试4个月时的BAILAMOS（c）计划和8个月时的BAILAMOS（c）维持活动对自我效能（介质）以及身体功能、认知功能和自我报告的功能限制和残疾的健康结局的影响。长期目标包括预防这一弱势群体的残疾。

DESCRIPTION (provided by applicant): Older Latinos are expected to constitute 20% of the older adult population by 2050. Physical activity (PA) can influence potential declines in the health outcomes of physical and cognitive function that lead to self- reported functional limitations and disability. Unfortunately, Latinos aged 65-74 are 46% less likely to engage in leisure time PA than older non-Latino whites, and little is known about PA maintenance among ethnic minorities. In part due to low levels of PA, older Latinos are twice as likely to report difficulty walking than non- Latino whites and Alzheimer's disease symptoms begin 7 years earlier in Latinos than in non-Latino whites. Participation in PA has substantial potential to help older Latinos maintain both physical and cognitive function as they age. Dance holds promise as a culturally appropriate form of PA for this disadvantaged population, and is a form of PA that challenges individuals both physically and cognitively. To date, PA programs designed for older Latinos are lacking. BAILAMOS(c) is a dance program that has been developed based on input from older community-dwelling Latinos and in collaboration with an accomplished Latin dance instructor. A single group, pre-post 3-month pilot of BAILAMOS(c) demonstrated substantial program feasibility, and effect sizes indicated greater self-reported participation in lifestyle PA, along with improvements in physical and cognitive function. The original 3-month BAILAMOS(c) dance program has been revised according to participant and dance instructor feedback. A randomized controlled trial (RCT) is proposed in sedentary, older Latinos at risk for disability. Participants will be randomized to the BAILAMOS(c) condition or a health education attention control group. BAILAMOS(c) encompasses four dance styles with the simplest style introduced first (i.e., Merengue) and the most difficult style last (i.e., Salsa) to enhance self-efficacy. Each style is taught for four weeks, twice weekly for one hour per class (32 sessions total). Group discussions on how to increase lifestyle PA are included. To enhance maintenance of PA after the formal program, 2-3 "indigenous leaders" from each site will be trained to teach the 4-months of dancing of BAILAMOS(c). Control condition activities consist of health education classes conducted in Spanish by bilingual/bicultural health educators of University of Illinois Extension. A total of 332 older Latinos will be recruited across nine sites over three years. Sites include senior centers, community centers, and parks. Each site will enroll approximately 40 individuals (20 treatment, 20 control). This clinical trial will test the impact of the BAILAMOS(c) program on lifestyle PA at 4 months and BAILAMOS(c) maintenance activities on lifestyle PA maintenance at 8 months. The impact of the BAILAMOS(c) program at 4 months and BAILAMOS(c) maintenance activities at 8 months on self-efficacy (mediators) and on health outcomes of physical function, cognitive function, and self-reported functional limitations and disability will be tested. Long term goals include the prevention of disability among this disadvantaged group.
