Targeting Physical Activity to Improve Cardiovascular Health in Type 2 Diabetes

Not Applicable

Completed

Brief Summary: This study plans to learn more about physical activity and physical function in sedentary older adults with type 2 diabetes.

Detailed Description: The purpose of this study is to conduct a randomized controlled trial with 1:1 patient-level randomization to an evidence-based physical activity program intervention versus usual care in sedentary older adults with type 2 diabetes in two primary care clinic sites.

Arm && Interventions

Group	Intervention	Description
Physical Activity Program Intervention	Physical Activity	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.
Usual Care Group	Questionnaires	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.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Objective Physical Activity at 4 Months	Baseline, 4 Months	ActiGraph accelerometer measures physical activity objectively as steps/week. These data are presented as the change from baseline values.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Physical Function at 4 Months	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).
