Brief Summary
Healthy Aging Resources to Thrive (HART) uses a rigorous two-stage randomized control design, adapted and refined based on pilot studies, to test a novel intervention to reduce sitting time in older adults. Half the participants will be randomized to the intervention aimed at decreasing sitting time, and the other half will be randomized to a healthy living control that does not focus on reduced sitting time. After 6 months, the intervention group will be further randomized so that half continue with the intervention and the other half receive no further intervention. All participants will be followed for 12 months.

Conditions
Outcome Measures
Primary Outcomes (3)
Change in Time Spent Sitting or Lying Down at 6 Months
Time (minutes) spent sitting/lying during waking hours will be measured objectively by the activPAL worn for one week following each measurement visit.
Change from Baseline at 6 months
Change in SystolicBlood Pressure at 6 Months
Another primary outcome is change in systolic blood pressure. This will be measured at the measurement visits using blood pressure monitors mailed to the participant
Change from Baseline at 6 months
Change in Diastolic Blood Pressure at 6 Months
Another primary outcome is change in diastolic blood pressure
Change from Baseline at 6 months
Secondary Outcomes (3)
Change in Weight at 6 Months
Change from Baseline at 6 months
Change in BMI at 6 Months
Change from Baseline at 6 months
Change in Waist Circumference at 6 Months
Change from Baseline at 6 months
Study Arms (2)
i-STAND
EXPERIMENTALi-STAND participants have a Baseline visit followed by the 1st Coaching visit. They receive wristbands that vibrate every 15 minutes to prompt a standing break, standing desks, workbook \& 10 phone-based coaching calls focused on sitting less/standing more. There is a 3 month measurement visit. Program ends at 6 months when they wear an activPAL \& have a measurement visit. Coach provides feedback on activPAL sitting time after all activPAL wears (Bsln, 3, 6 \& 12 month). They may opt to wear activPAL at 6 weeks \& get feedback. They are re-randomized at 6 months; half to be assigned to intervention boosters (5 more phone sessions/a 9-month optional activPAL) before the 12 month final activPAL \& final measurement visit. Those not randomized to boosters will have no contact until the 12 month visit. UPDATE: As of 3/31/2022, (final year 5), i-STAND ppts will no longer be re-randomized at 6 months. We will no longer follow to the 12-month timepoint \& will end all activities after 6-months.
Healthy Living control
ACTIVE COMPARATORIn this arm, participants have a phone-based Baseline visit followed by the 1st phone-based Coaching visit. No prompting devices/desks are offered; coaching focuses on topics related to healthy living, but with no focus on sitting less/standing more. They have 10 phone calls with a health coach. Participants receive a workbook. All content is from KaiserPermanente WA and is available to all members. Participants select topics \& review them with their health coach. At 3 months, participants have a measurement visit. The program ends at 6 months where participants will wear an activPAL and have a measurement visit. After that, there is no contact with the study team until 12 months when they will again wear an activPAL \& have a final measurement visit. UPDATE: As of 3/31/2022, our final year (year 5) of the study, participants randomized to the control arm will no longer be followed to the 12-month timepoint and will end all activities after the 6-month timepoint.
Interventions
Via in-person and phone coaching sessions, participants randomized to this arm will be coached to find ways to sit less and stand more, and look for ways to change their home environment to encourage this, as well as look at how their lifestyle may contribute to their sitting time. Participants in this arm may be re-randomized at the half-way point to continue with additional phone coaching sessions. (As of 3/31/2022 Re-randomizations are no longer taking place)
In this arm, participants will have phone coaching sessions focused on a variety of topics aimed at improving healthy habits. There is no focus on standing more or sitting less.

Limitations and Caveats
Limitations of our study include the interruption caused by the COVID-19 pandemic, which occurred after 100 of the 283 participants were enrolled. We had to rely on participant-measured outcomes post-pandemic.
