Participant Flow

A total of 55 people were determined to be eligible for this study, however 5 of them withdrew prior to randomization. This explains the discrepancy between Protocol section (n=55) and Participant Flow Module (n=50).

Measure
Physical Activity Program Intervention
The intervention seeks to increase physical activity and improve strength by addressing individual , behavioral, and social/environmental factors. Health promotion clinic staff will deliver counseling by phone on a bi-weekly basis - a clinic physician assistant will coordinate with the counselor during in-person clinic visits, teach participants to perform strengthening exercise, and assess for safety concerns associated with type 2 diabetes. In addition to behavioral counseling targeting social cognitive theory constructs, counselors will assist participants in the intervention group to set specific goals for physical activity in a paper log and on an electronic FitBit activity tracking device.Health promotion clinic staff will encourage participants to advance goals towards meeting U.S. physical activity guidelines of 150 minutes/week of moderate intensity activity and 2-3 days/week of strength activities. Physical Activity: Physical Activity Program Intervention
Usual Care Group
Participants in the usual care arm will receive three mailings (Intervention Questionnaires) during the intervention phase. Health promotion clinic staff will mail materials from the Center for Disease Control and Prevention website that address general health aging topics. Questionnaires: Participants in the usual care arm will receive three mailings during the intervention phase.

Interval -17.6 to 32.3

SECONDARY outcome

Timeframe: Baseline, 4 Months

Measured via the Short Physical Performance Battery (SPPB), which evaluates balance, usual walking speed, and repeated chair rise. These data are presented as the change from baseline values where higher values indicate better physical function (scoring range 0-12).
