NURSING INTERVENTION FOR MIDLIFE WOMEN--WALKING PROGRAM

描述：（改编自研究者摘要） 研究是为了确定一个24周的家庭为基础的，温和的 强度步行计划在缓解常见的生理和心理 健康症状和改善身体素质和运动行为， 久坐不动的中年女性 具体目的是：（1）比较 妇女的健康症状，身体素质和运动动机后， 完成步行计划与自己的preprogram措施和那些 非锻炼者的对照组;（2）确定 治疗前后健康症状和身体状况的变化量 健康状况;（3）比较健康症状，身体素质和运动 在完成步行计划后24周， 立即postprogram分数;和，（4），以确定的影响， 步行计划之间的关系健康症状和他们已知的 相关（即，角色质量、绝经状态、绝经态度）。 受试者将是174名明显健康、久坐不动、不肥胖的女性， 40 - 60岁的中年妇女有常见的健康症状， 未接受HRT，未怀孕，未进行双侧卵巢切除术。 将从有雇员的大型组织中寻找志愿者 代表着不同的种族和社会经济群体。 受试者将 随机分配到实验组或对照组， 交叉设计 拟议的干预措施不需要任何设备， 将在个人方便的时间和地点进行 妇女 将规定以50 - 74%的HRmax储备行走，并从 20至30分钟的连续步行，每周4次，持续24周 期 在24周结束时，对照组将开始相同的治疗 实验组将被监测24周以上， 决定他们是否继续步行计划。 期间的遵守情况 干预阶段将通过运动日志和无线心率进行评估 在继续阶段，仅通过练习日志进行监测。 每2 周，实验组将完成健康症状测量， 获得反馈和支持，以确保遵守和取得进展。 对照组 我也会每2周完成一次健康症状监测措施 并以对照组为接触实验组。 其他 在0周和24周时对两组进行的测量将解决以下因素： 已知影响中年症状（月经史;激素测定 促卵泡激素、雌二醇、雌酮; 更年期;角色品质）;运动动机（运动自我效能， 运动自我决定论）;和身体健康，包括有氧健身 （最大运动试验），身体成分（体重指数，双能 X线吸收测定法）和柔韧性（数字倾斜仪）。 行使 动机，身体健康和健康症状将在48岁时重新评估 周 行走方案是自变量;因变量 是健康症状，健身，运动动机和持续性。 计划的分析包括方差分析、重复测量方差分析、配对比较t检验和方差分析。 测试和多重回归。 积极成果将支持 在家中进行中等强度运动， 非药物性缓解健康症状。

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.
