Clinical Trial Summary

The purpose of this study is to see if exercise is helpful for improving memory, concentration thinking abilities, physical function, and quality of life for adults aged 50 to 89 years living with HIV and who have two or more cardiovascular disease risk factors. The study will test two kinds of intervention exercises: one group will walk for exercise and the second group will stretch for exercise. Members of both interventions will be asked to participate in one-on-one interviews/assessments, measures of physical functioning, and some sessions with others who are also enrolled in the study.

Description:

This is a two arm, randomized controlled trial to test the longitudinal effects of the Let's Move Program (walking for exercise) compared to effects of the attention control Let's Flex Program (stretching for exercise) in participants aged 50 to 89 years living with HIV and who have two or more cardiovascular disease risk factors. Participants in both interventions will be asked to participate in one-on-one interviews/assessments, measures of physical functioning, and some sessions with others who are also enrolled in the study. Participants will participate in an in home exercise program for twelve weeks in which the study team will help identify maximum duration and intensity followed by a maintenance period for weeks 13-58.

Intervention

Behavioral:
• Let's Move Program
Participants will be asked to walk five times per week for twelve weeks for a minimum of 30 minutes while wearing a heart rate monitor and a pedometer. Participants will also receive weekly telephone calls from a member of the research team to monitor walking progress and to change walking duration or intensity level based on their progress.After the twelve week period, participants will enter a maintenance exercise phase for weeks 13-17 in which they will be asked to maintain their exercise regimen.
• Let's Flex Program
Participants will be asked to stretch five times per week for twelve weeks for a minimum of 30 minutes. Participants will also receive weekly telephone calls from a member of the research team to monitor progress and to change duration or intensity level based on their progress.After the twelve week period, participants will enter a maintenance exercise phase for weeks 13-17 in which they will be asked to maintain their exercise regimen.
• Group Motivational Interviewing
Participants will attend four separate group intervention sessions for 2.5 hours for four consecutive weeks at the beginning of the program. Groups will consist of 6-8 members and will focus on the rationale for aerobic exercise, barriers to exercise, finding time for exercise, how to set short and long term exercise goals, and use of self-monitoring to improve exercise engagement.

Other	Pittsburgh Sleep Quality Index (PSQI) Score	The Pittsburgh Sleep Quality Index (PSQI) is a 19-item measure of the quality and patterns of sleep among adults. Scoring is based on a 0 to 3 Likert scale. The global score is 21; total possible score ranges from 0 to 21. The higher the score the worse the sleep quality.	Baseline, T2 (28-30 weeks post baseline), T3 (56-58 weeks post baseline)
Other	Beck Depression Inventory-II (BDI-II) Score	BDI-II is a 21-question multiple-choice self-report inventory, one of the most widely used instruments for measuring the severity of depression. Each answer being scored on a scale value of 0 to 3. Scores range from 0-63. Interpretation: 0 through 9 indicate no or minimal depression; scores from 10 through 18 indicate mild to moderate depression; scores from 19 through 29 indicate moderate to severe depression; and scores from 30 through 63 indicate severe depression.	Baseline, T2 (28-30 weeks post baseline), T3 (56-58 weeks post baseline)
Other	Exercise Regimen as Assessed by the Community Healthy Activities Model Program for Seniors (CHAMPS) Questionnaire	The 41-item Community Healthy Activities Model Program for Seniors evaluates weekly duration of various types of physical activity among older adults including light, moderate and vigorous intensity levels. The activity is assessed by hours per week using 6 categories less than 1 hour to 9 or more hours. The values presented below are hours participants indicated they spent in moderate intensity activity levels at the 3 time points over the past 4 weeks. Guidelines suggest 150 minutes (2.5 hours) per week in moderate intensity physical activity, below this number is considered sedentary. We measure change from baseline in time spent in moderate intensity exercise.	Baseline, T2 (28-30 weeks post baseline), T3 (56-58 weeks post baseline)
Other	V02 Max Rate	V02 max is the maximum rate of oxygen consumption as measured during incremental exercise using the Balke treadmill test. This is an exploratory outcome.	Baseline
