简要总结
The objective of this pilot study is to quantify patterns of activity and sedentary behavior in independent living residents and to collect preliminary data on the feasibility of reducing sedentary behavior using a 12-week, behavioral intervention in older adults. We will also measure the effects of reducing sedentary behavior on physical function, sleep, quality of life, energy/mood, pain and blood pressure. Participants will act as their own controls through the use of a double baseline period to examine stability of the physical activity and outcome measures.
详细描述
Aim 1: To measure the amount of sedentary time and ambulation (steps) in older adults residing in independent living communities.
Aim 2: To test the acceptability and effectiveness of a 12-week sedentary behavior intervention to decrease sitting and increase ambulation which will in turn improve physical function (primary outcome) as well as sleep, quality of life, energy/mood, pain and blood pressure (secondary outcomes) in independent living residents.
Background: Sedentary behavior, or sitting for prolonged periods during waking time, is identified as a health risk that is distinct from the failure to achieve sufficient physical activity. Older adults exhibit the greatest time in sedentary behavior which is concerning given its association with chronic disease and poorer physical function. Preliminary data suggest that individuals in long term care facilities may have even greater sedentary time due to personal factors and environment influences. Most often, exercise is targeted as a mechanism for ameliorating frailty in older adults; however, reduction in sedentary time may be a more appealing and realistic goal for improving health outcomes. Despite this, studies targeting sedentary time in older adults, particularly in those in independent living facilities, are lacking.

- •Reside in an independent living facility
- •Ability to walk approximately 100 feet (length of a hallway) with or without an assistive device
排除标准
- •Unable to provide informed consent

研究组 & 干预措施
Sedentary Behavior Intervention
A behavioral intervention that targets prolonged sitting and encourages frequent activity breaks.
干预措施: Reduction in Sedentary Behavior (Behavioral)
结局指标
主要结局
Change in Sedentary Behavior
时间窗: Baseline to 12 weeks
Objectively measured minutes of sitting during waking hours measured using the ActivPAL physical activity monitor for a minimum of 5 days pre and post-intervention. The ActivPAL is a thigh-mounted, compact device that classifies an individual's free-living activity into time spent in sedentary, standing, and walking behaviors.
Steps per Day
时间窗: Baseline to 12 weeks
The number of steps per day measured using the ActivPAL activity monitor. This monitor is worn for a minimum of 5 days before and after the intervention.
Short Physical Performance Battery
时间窗: Baseline to 12 weeks
This performance-based measure of physical function is a battery of measures to assess standing balance, gait speed and lower extremity strength (time to complete five chair rises)
Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function Short Form 10a
时间窗: Baseline to 12 weeks
This self-report measure of physical function has 10 questions that assess the ability to perform various activities that require physical capability.
