NCT00594399

Brief Summary

This study targets older adults (ages 60 and over) who are overweight (body mass index 25-40) with impaired fasting glucose (100 - 125). We propose a three-year, randomized controlled clinical trial (n=300) to determine the effect of a one-year physical activity counseling intervention on glucose metabolism and secondary outcomes compared to usual care.

Outcome Measures

Primary Outcomes (6)

  • Fasting Insulin

    Fasting Insulin analyzed at VA central laboratory by technicians not affiliated with study. Participants were instructed to refrain from eating or drinking anything except water and medications past midnight. A reminder call was placed the night before the scheduled appointment and fasting was verified by study personnel before appointed blood draws.

    Baseline

  • 3 Month Fasting Insulin

Study Arms (2)

Arm 1 Physical Activity counseling

EXPERIMENTAL

Physical activity (PA) counseling program with the following components: baseline in-person counseling session; telephone calls, one physician endorsement of PA in a primary care clinic visit, monthly automated telephone calls from the primary care provider encouraging PA; and quarterly mailed materials providing personalized feedback.

Behavioral: Physical Activity Counseling

Arm 2

NO INTERVENTION

Usual care from primary, womens or geriatric clinics

Interventions

Physical activity (PA) counseling program with the following components: a baseline in-person counseling session; telephone calls biweekly for 6 weeks then monthly; one physician endorsement of PA in a primary care clinic visit; monthly automated telephone calls from the primary care provider encouraging PA; and (5) quarterly mailed materials providing personalized feedback.
