Obesity and frailty are positively linked. Compared to other groups, older African American women have the highest rates of both obesity and frailty. Several academic weight loss interventions have shown that older adults can lose weight and improve physical function through diet and exercise. However, these programs do not have infrastructure for dissemination. Take Off Pounds Sensibly (TOPS) is a peer-led, community-based weight loss program with TOPS has a nationwide infrastructure that facilitates dissemination. Retrospective analyses showed that TOPS participants could lose a clinically significant amount of weight and maintain the loss for up to 7 years. This study will evaluate how TOPS participation affects weight change; physical function; cardiovascular disease risk factors; quality of life; and healthcare utilization among older African American women.
We are recruiting 104 older African American women aged ≥55 years with a BMI ≥ 27 kg/m to participate in a 6-month randomized wait-list controlled trial where TOPS is facilitated by a dietitian in weekly meetings. The primary goal of the intervention is for participants to lose at least 5 % of their initial weight. Outcomes will be collected at study visits at baseline, 3 months, and 6 months.
If successful, this study will show that the TOPS program would be an option to treat excess weight and poor physical function among older African American women.
肥胖与身体虚弱呈正相关。与其他群体相比,年长的非裔美国女性肥胖率和身体虚弱率最高。多项学术性减肥干预措施表明,老年人可通过饮食和运动实现减重并改善身体机能。然而,这些项目缺乏推广的基础设施。“明智减重”(TOPS)是一个由同伴主导、基于社区的减肥项目,TOPS在全国范围内拥有便于推广的基础设施。回顾性分析表明,TOPS参与者能够减掉临床上显著的体重,并在长达7年的时间里维持体重减轻状态。本研究将评估参与TOPS如何影响体重变化、身体机能、心血管疾病风险因素、生活质量以及年长非裔美国女性的医疗保健利用情况。
我们正在招募104名年龄≥55岁、体重指数(BMI)≥27kg/m²的年长非裔美国女性,参与一项为期6个月的随机等待名单对照试验,由一名营养师在每周的会议上协助开展TOPS项目。干预的主要目标是让参与者至少减掉其初始体重的5%。将在基线、3个月和6个月的研究访视时收集结果。
如果成功,本研究将表明TOPS项目可作为治疗年长非裔美国女性超重和身体机能不佳的一种选择。
