Brief summary
The purpose of the expanded study is to examine the effectiveness of a Stand Up and Move More intervention to reduce sedentary behavior in older adults from underserved communities.
Detailed description
Based on successful pilot research in Rock County, WI, and the receipt of funding from the National Institutes of Health, the investigators expanded research to additional counties in Wisconsin for a total of four counties (i.e., Dane, Iowa, Rock, and Vilas counties). Sample size will increase and participants will be randomly assigned to the intervention group (Stand Up and Move More group) or a wait-list control group (who receive the intervention after 12 weeks). The Stand Up and Move More intervention/workshop involves sessions once/week for four weeks with a refresher session at 8 weeks. Assessments will be conducted before the intervention/workshop begins, and then again at 4 weeks and 12 weeks. We have added several questionnaires to examine potential mediators of behavior change (e.g., self-efficacy, self-regulation, outcome expectancies).

Inclusion criteria
* adults older than 55 yrs of age * inactive or low active (i.e., less than 60 minutes of physical activity/week) * residents of Dane, Iowa, Rock or Vilas counties, and * residing in a home or an apartment.
Exclusion criteria
* low levels of sedentary behavior (less than or equal to 6 hours/day), * recent hospitalization (i.e., past month), * uncontrolled medical conditions including: uncontrolled hypertension, heart disease, actively receiving chemotherapy or palliative care for cancer, stage 4 liver disease, end-stage renal or pulmonary disease, severe arthritis or any other orthopedic condition that could be made worse by standing up and moving more; * inability to stand up without assistance of another person, and * inability to speak or hear spoken English.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total Sedentary Time Per Day | Baseline, 4 weeks, 12 weeks | Participants wore monitors during the day to assess total sitting time/day |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Short Physical Performance Battery (SPPB) Score | Baseline, 4 weeks, 12 weeks | The SPPB is an assessment of physical limitations. It combines scores from a balance test, gait speed test, and a chair stand test. The total possible range of scores is 1-12, higher scores indicate better function/less functional limitations. |

Outcome results
Primary
Total Sedentary Time Per Day
Participants wore monitors during the day to assess total sitting time/day
Time frame: Baseline, 4 weeks, 12 weeks
Population: The number of participants analyzed differs for each time point due to participant availability, attrition, and not all participants wore the monitors per protocol for each visit (10 hours/day for a full week each time point).
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Stand up Intervention | Total Sedentary Time Per Day | Baseline | 618 minute/day | Standard Deviation 119 |
| Stand up Intervention | Total Sedentary Time Per Day | 4 weeks | 564 minute/day | Standard Deviation 119 |
| Stand up Intervention | Total Sedentary Time Per Day | 12 weeks | 602 minute/day | Standard Deviation 116 |
| Control | Total Sedentary Time Per Day | Baseline | 660 minute/day | Standard Deviation 153 |

Secondary
Short Physical Performance Battery (SPPB) Score
The SPPB is an assessment of physical limitations. It combines scores from a balance test, gait speed test, and a chair stand test. The total possible range of scores is 1-12, higher scores indicate better function/less functional limitations.
Time frame: Baseline, 4 weeks, 12 weeks
Population: The number of participants analyzed differs for each time point due to participant availability and attrition.
