Trial Summary

What is the purpose of this trial?

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.

Eligibility Criteria

This trial is for overweight, postmenopausal women aged 55 and above who are medically stable. Participants should be able to stand and walk without a high risk of falling, have a BMI between 25-45, sit for more than 7 hours daily, do less than 70 sit-to-stand transitions per day, and must be fluent in English.

Inclusion Criteria

able to travel to study visits

55 years of age and above

medically stable without any health conditions that would inhibit standing or PA

Exclusion Criteria

younger than 55 years of age

sit for less than 7 hours per day, perform 71 or more sit-to-stand transitions per day

mental state that would preclude complete understanding of the protocol or compliance

Treatment Details

Interventions

• activPAL inclinometer
• Health Coaching
• Tools to Prompt Standing or Prompt Sit-to-Stand Transitions

Trial Overview The study tests if health coaching or tools that prompt standing can interrupt sedentary behavior in older women. It's part of the STAR program aiming to understand how breaking up sitting time affects healthy aging. Women will randomly receive one of these interventions.

Participant Groups

Group I: Sit-to-Stand Transition Experimental Treatment 3 Interventions

Participants in the Sit-to-Stand Transition condition will receive an intervention aimed at increasing the daily number of brief sit-to-stand transitions. This group will receive five in-person health coaching sessions and two phone counseling sessions.

Group II: Reduce Sitting Experimental Treatment 3 Interventions

Participants in the Reduce Sitting condition will receive an intervention aimed at reducing daily sitting time. This group will receive five in-person health coaching sessions and two phone counseling sessions.

Group III: Health Living Attention Control Active Control 1 Intervention

Participants in the attention control condition will receive a healthy aging educational intervention. This group will receive one in-person health coaching sessions and 6 phone counseling sessions.
