DESCRIPTION (provided by applicant): One-third of adults over 65 are obese. While previous studies have focused on promoting physical activity to reduce the health burdens of obesity and aging, physical activity levels have remained low among older adults and those with obesity. One explanation may be that the barriers to engaging in moderate intensity physical activity are too high for obese older adults (e.g. low physical function, pain, lack of motivation). At the same time, obese older adults spend over 10 hours per day sitting, more than any other age group. Emerging research now shows that sitting time has adverse health impacts, independent of meeting physical activity guidelines. Overcoming the barriers to reducing sedentary time may be a more feasible health-promoting behavior for obese older adults. Thus, we aim to explore a new approach to improving the health of obese older adults, who are at high risk for having or developing chronic health conditions, by focusing on reducing sedentary time. In our preliminary work, we developed procedures and intervention materials, showed reductions in sedentary time in a small one arm study, and established preliminary feasibility of our approach. The current randomized pilot study will formally assess the feasibility, acceptability, and impact of our innovative phone-based intervention designed to decrease sitting time and increase light intensity physical activity among sedentary obese older adults using a longer and more intensive intervention. We will compare the intervention to an attention-matched comparison group that receives a healthy aging education program (30 participants per group). Study outcomes, including sedentary time and sit-to-stand transitions (from activPAL inclinometers), light intensity physical activity (from accelerometers), and cardiovascular risk factor biomarkers will be measured at 12 weeks. If the intervention is feasible and shows promise for reducing sedentary time, we will plan a future randomized efficacy trial. In addition to reducing sedentary behavior, the long-term objective of this research is to create an effective intervention that will allow researchers to better understand the potential health impacts of reducing sitting among older and obese adults. To date, no such empirically validated interventions exist. As such, this formative research stands to make a unique and meaningful contribution to this field of research. This work is well-aligned with NIA's strategic focus on examining ways to promote healthy and active aging among those with chronic conditions.

描述（由申请人提供）：65岁以上的成年人中有三分之一是肥胖。虽然先前的研究集中在促进体育锻炼以减轻肥胖和衰老的健康负担，但老年人和肥胖者的身体活动水平仍然很低。一种解释可能是，从事中等强度的体育活动的障碍对于肥胖的老年人来说太高（例如身体机能低下，疼痛，缺乏动力）。同样 时间，肥胖的老年人每天坐着10个小时以上，比其他任何年龄段的人都多。现在，新兴的研究表明，就业时间与身体活动指南无关。克服减少久坐时间的障碍对于肥胖老年人来说可能是更可行的健康行为。因此，我们旨在通过专注于减少久坐的时间来探索一种新的方法来改善患有或发展慢性健康状况的高风险或发展慢性健康状况的新方法。在我们的初步工作中，我们开发了程序和干预材料，在一项小型手臂研究中显示出久坐时间的减少，并确定了我们方法的初步可行性。当前的随机试验研究将正式评估我们基于电话的干预措施的可行性，可接受性和影响，旨在减少坐姿并增加久坐的肥胖老年人之间的光强度体育锻炼，并使用更长的强化干预措施。我们将将干预措施与接受健康衰老教育计划的注意力匹配的比较组（每组30名参与者）进行比较。研究结果，包括久坐的时间和静坐过渡（来自Activpal倾向），光强度体育活动（来自加速度计）和心血管危险因素生物标志物将在12周时测量。如果干预是可行的，并显示出减少久坐时间的希望，我们将计划未来的随机效力试验。除了减少久坐行为外，这项研究的长期目标是创建有效的干预措施 让研究人员更好地了解减少老年人和肥胖成年人中坐的潜在健康影响。迄今为止，尚无此类经验验证的干预措施。因此，这项形成性研究将为这一研究领域做出独特而有意义的贡献。这项工作与NIA的战略专注于研究慢性疾病患者的健康和积极衰老的方法相结合。
