Sedentary Behavior Interrupted: A Randomized Trial of 3-month Effects on Biomarkers of Healthy Aging and Physical Functioning in the Real World (Project 2)
In Brief
A clinical study evaluating Health Coaching, activPAL inclinometer, and 1 other intervention for Sedentary Lifestyle. Completed, enrolled 407 participants across 1 site.
Detailed Summary
Epidemiological findings indicate that older adults do not meet physical activity (PA) guidelines \& spend up to 11 hrs/day sitting. Given the high prevalence of sedentary behavior (SB), the higher chronic disease risk in this population, \& the age-associated challenges of meeting traditional PA guidelines, involving longer bouts of moderate PA, the investigators hypothesize that older adult health will benefit from new strategies to interrupt sitting. This protocol "Sedentary Behavior Interrupted: A randomized trial of 3-month effects on biomarkers of healthy aging and physical functioning in the real world (Project 2)" is part of a National Institutes of Aging Program Grant called "Sedentary Time \& Aging Mortality and Physical Function (STAR). The overall purpose of the STAR program to is to better understand how to interrupt sitting time and the consequences for healthy aging in postmenopausal women. This protocol (also referred to Project 2 of the STAR program) is a 3-arm randomized control trial designed to assess ways of interrupting sitting in 405 overweight, postmenopausal women.
Study Details
Timeline
Interventions
Health Coaching sessions will be aimed at goal setting, implementing strategies, overcoming barriers, \& relapse prevention.
Participants in the intervention study arms (B \& C) will wear the ActivPAL device for the first 4 weeks of the program and then again in weeks 8 and 9. The device will monitor their sitting and standing time and will allow Health Coaches to provide feedback and will assist the participant in developing an action plan.
Participants in the intervention study arms (B \& C) will receive tools to prompt standing or sit-to-stand transitions such as wearable wrist devices, standing desks or tables (Group B only), mechanical and/or electronic timers, or access to mobile apps or computer programs.
