Approximately 50% of people living with HIV (and as many as 80% over the age of 50) have difficulties with cognitive functions such as memory and thinking that can have a profound negative impact on activities of daily living and quality of life. Problems with memory and thinking are also associated with forgetting to take anti-retroviral drugs and experiencing challenges to balance, walking and mental health (anxiety and depression). There is increasing evidence that, in the general population, exercise has positive effects on cognition, physical functioning and mental health. Despite the recognition of multiple therapeutic benefits of exercise, little attention has been paid to its possible effects on cognition in people living with HIV. The purpose of the proposed pilot study is to compare the effects of a 12-week, randomly assigned, community-based yoga-mindfulness intervention on cognition, balance, walking, mental health and quality of life in 30 people >35 years of age living with HIV in the Halifax area. Yoga is of particular interest because it encompasses not only the physical but also spiritual, emotional, and mental dimensions of life. As such, it has tremendous potential to help stave off some of the devastating consequences of HIV infection.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Yoga-mindfulness | Experimental | Groups of 4-5 participants will engage in group-based sessions supervised by yoga-certified physiotherapists, 60 minutes per intervention/session, 3 sessions/week for 12 weeks. The yoga-mindfulness group will participate in a 60-minute Hatha-style yoga class, with meditation, active postures for strengthening and balance, and breathing exercises. Participants will be tracked for total distance and steps per day using accelerometers (Fitbit Flex). |
|
| Control | No Intervention | Participants in this group will not participate in an exercise program. They will be tracked for total distance and steps per day using accelerometers (Fitbit Flex). |

Cognition, motor function (balance, walking speed), and affective (mental health, quality of life, medication adherence) evaluations will be administered at baseline and post-intervention (12 weeks) by a trained physiotherapist, blinded to the group assignment. The rationale for blinding the assessing physiotherapist is to reduce bias in scoring during the outcome assessment sessions.
|
Balance will be measured using the Community Balance and Mobility test (CB&M). |
| Assessed at baseline and at 12 weeks. |
| Walking Speed | Walking peed will be measured using the 10-meter walking test because it is a simple, well-recognized global health indicator that can predict survival probability. | Assessed at baseline and at 12 weeks. |
| Depression | Depression will be assessed using the Hospital Anxiety and Depression Scale, a self-report questionnaire. | Assessed at baseline and at 12 weeks. |
| Medication Adherence | Participants will also be asked about Medication adherence (specifically antiretroviral) using the Simplified Medication Adherence Questionnaire (SMAQ). | Assessed at baseline and at 12 weeks. |
| Health-related Quality of Life | Quality of life will be assessed using MOS-HIV, consisting of 10 domains (health perceptions, physical/role/ social functioning, pain, mental health, vitality, health distress, cognitive function, QOL). | Assessed at baseline and at 12 weeks. |
