项目摘要

DESCRIPTION (provided by applicant): According to the National Institutes of Health, "obesity is one of the most daunting health challenges of the 21st century". Approximately 2/3 of all adults are overweight or obese. Efforts to abate the growing prevalence of obesity have not been successful. The Strategic Plan for NIH Obesity Research proposes preventing and treating obesity through lifestyle modification. The purpose of this study is to evaluate the effectiveness of a theory-based intervention framed within the Health Promotion Model (HPM) in facilitating weight loss and maintenance through promotion of healthy eating and physical activity among an underserved, vulnerable population of overweight or obese rural women aged 50-69. During these years, women experience increases in peri- and post-menopausal health risks that are magnified if they are overweight or obese. Weight loss will reduce risks and enhance functional status as they age. Maintenance of weight loss will be emphasized. The Internet offers a way to reach isolated rural women who have limited options for weight loss guidance. A convenience sample of 306 rural women age 50-69 with body mass index 28 to 39.9 will be randomized into 3 groups. All participants will access a theory-based interactive Internet site based on constructs in the HPM and addressing recommended approaches to healthy eating and physical activity for weight loss and maintenance. One group will use the Internet site only, a second group will participate in a supplemental peer-led online support group, and a third group will receive supplemental professional weight loss counseling via e-mail. This study will have 3 phases: guided initial weight loss (6 months), guided continuing weight loss/maintenance (12 months) and self-directed weight maintenance (12 months); the 30-month period will allow time for women to establish lifestyle changes to achieve weight maintenance. The maintenance phases will provide a transition to a permanent healthy lifestyle during the time of high risk for regain. The primary outcomes will be change in body weight, eating, and activity at 3, 6, 12, 18, 24, & 30 months. At least 5% and preferably 10% of loss of weight without regain will be the realistic targets emphasized in this study. Change in behavior-specific cognitive/ perceptual influences from the HPM also will be examined to validate the theory base for the intervention. If successful, this research study will have implications beyond Nebraska for reaching rural populations through the Internet for weight loss and maintenance.

描述(申请人提供)：根据美国国立卫生研究院的说法，肥胖是21世纪最令人望而生畏的健康挑战之一。大约三分之二的成年人超重或肥胖。遏制日益严重的肥胖症的努力并未取得成功。美国国立卫生研究院肥胖研究战略计划建议通过改变生活方式来预防和治疗肥胖。这项研究的目的是评估健康促进模式(HPM)框架内的基于理论的干预措施的有效性，该干预措施通过在50-69岁超重或肥胖的农村妇女中促进健康饮食和体育活动来促进减肥和维持体重。在这些年里，女性围绝经期和绝经期后的健康风险增加，如果她们超重或肥胖，这种风险就会放大。随着年龄的增长，减肥将降低风险并提高功能状态。将强调保持减肥。互联网提供了一种接触与世隔绝的农村妇女的方式，她们的减肥指导选择有限。随机抽取306名50-69岁、体重指数为28-39.9的农村妇女作为研究对象，随机分为3组。所有参与者都将访问一个基于理论的互动互联网网站，该网站基于HPM中的结构，并提出了健康饮食和体力活动的推荐方法，以减肥和保持体重。其中一组将只使用互联网网站，第二组将参加一个由同伴领导的补充在线支持小组，第三组将通过电子邮件接受补充的专业减肥咨询。这项研究将分为三个阶段：指导初始减肥(6个月)，指导持续减肥/维持(12个月)和自我指导减肥(12个月)；30个月的时间将让女性有时间改变生活方式，实现减肥。维持阶段将提供一个过渡到永久健康的生活方式，在高风险的恢复期间。主要结果将是在3、6、12、18、24和30个月时体重、饮食和活动量的变化。在这项研究中强调的现实目标是至少5%，最好是10%的体重减轻而不会恢复。还将研究HPM对特定行为的认知/知觉影响的变化，以验证干预的理论基础。如果成功，这项研究将对内布拉斯加州以外的农村人口通过互联网减肥和保持体重产生影响。
