NURSING INTERVENTION FOR MIDLIFE WOMEN--WALKING PROGRAM

描述：(改编自调查人员摘要)目的 研究是为了确定一项为期24周的居家治疗的有效性，适中 强度步行方案在缓解常见身心问题中的作用 健康症状与改善身体素质和锻炼行为 久坐不动的中年女性。具体目标是：(1)比较 女性运动后的健康症状、身体素质和运动动机 用他们自己的计划前措施完成步行计划 不锻炼的控制组；(2)找出 计划实施前后健康症状和身体状况的变化量 健身；(3)比较健康症状、身体健康和锻炼情况 在完成步行计划24周后进行动力测量 计划后即刻评分；以及，(4)确定 步行计划对健康症状与其已知症状之间的关系 相关因素(即角色质量、更年期状态、更年期态度)。 受试者将是174名明显健康、久坐、非肥胖的老年女性 40-60岁正在经历中年女性常见的健康症状的人 没有接受激素替代治疗，没有怀孕，也没有做过双侧卵巢切除术。 志愿者将从有员工的大型组织中招募 代表不同的种族和社会经济群体。主题将是 在实验中随机分配到试验组或对照组 跨界设计。拟议的干预将不需要设备和 将在个人方便的时间和地点进行 女人。步行将被规定为50-74%的HRmax储备，并从 在24周内每周连续步行4次，每次20至30分钟 句号。在24周结束时，对照组开始同样的治疗 计划，试验组将再接受24周的监测 确定他们是否继续步行计划。在此期间坚持 干预阶段将通过运动日志和无线心率进行评估 在持续阶段，仅通过运动日志进行监测。每2个人 两周后，试验组将完成健康症状措施和 获得遵守和进步方面的反馈和支持。对照组 还将每2周完成一次健康症状监测 并以症状为对照，与实验组接触。其他 在0周和24周对两组实施的措施将解决这些因素 已知会影响中年症状(月经史；荷尔蒙检测 卵泡刺激素、雌二醇、雌酮；对 更年期；角色品质)；运动动机(运动自我效能、 运动自我决定论)；以及身体健康，包括有氧健身 (最大运动试验)，身体成分(身体质量指数，双能 X射线吸收法)和灵活性(数字倾斜仪)。锻炼 动机、身体健康和健康症状将在48岁时重新评估 几周。步行程序是自变量；因变量 是健康症状、健康状况、运动动机和持续性。 计划分析包括方差分析、重复测量方差分析、配对比较t 测试和多重回归。积极的结果将支持 以家庭为基础的中等强度运动对 对健康症状的非药物缓解。

DESCRIPTION: (Adapted from investigator's abstract) The purpose of this study is to determine the effectiveness of a 24-week home-based, moderate intensity walking program in alleviating common physical and psychological health symptoms and improving physical fitness and exercise behavior in sedentary employed midlife women. The specific aims are: (1) to compare women's health symptoms, physical fitness, and exercise motivation after completing the walking program with their own preprogram measures and those of a control group of nonexercisers; (2) to identify relationships among the amount of change in pre- to postprogram health symptoms and physical fitness; (3) to compare health symptoms, physical fitness, and exercise motivation measures 24 weeks after completing the walking program with immediate postprogram scores; and, (4) to determine the effect of the walking program on the relationships between health symptoms and their known correlates (i.e., role quality, menopausal status, menopausal attitude). Subjects will be 174 apparently healthy, sedentary, nonobese women aged 40-60 who are experiencing health symptoms common to midlife women and who are not on HRT, are not pregnant, and have not had a bilateral oophorectomy. Volunteers will be sought from large organizations with employees representing diverse ethnic and socioeconomic groups. Subjects will be randomly assigned to an experimental or control group in an experimental crossover design. The proposed intervention will require no equipment and will be carried out at times and locations convenient to the individual women. Walking will be prescribed at 50-74% HRmax reserve and progress from 20 to 30 minutes of continuous walking 4 times per week over a 24-week period. At the end of 24 weeks, the control group will begin the same program, and the experimental group will be monitored for 24 weeks more to determine whether they continue the walking program. Adherence during the intervention phase will be assessed by exercise logs and wireless heart rate monitors and during the continuation phase by exercise logs only. Every 2 weeks the experimental group will complete health symptoms measures and receive feedback and support for adherence and progress. The control group will also complete the health symptoms measures every 2 weeks to monitor symptoms and to control for contact with the experimental group. Other measures administered to both groups at 0 and 24 weeks will address factors known to influence symptoms at midlife (menstrual history; hormonal assays of follicle-stimulating hormone, estradiol, estrone; attitude toward menopause; role quality); exercise motivation (exercise self-efficacy, exercise self-determinism); and physical fitness, including aerobic fitness (maximal exercise test), body composition (body mass index, dual-energy x-ray absorptiometry), and flexibility (digital inclinometer). Exercise motivation, physical fitness, and health symptoms will be reassessed at 48 weeks. The walking program is the independent variable; dependent variables are health symptoms, fitness, exercise motivation, and continuation. Planned analyses include ANOVA, repeated-measures ANOVA, paired comparison t tests, and multiple regressions. Positive outcomes will support the effectiveness of home-based, moderate intensity exercise for nonpharmacological relief of health symptoms.
