Brief Summary:
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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 22 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Masking Description: 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.
Primary Purpose: Treatment

Arm Intervention/treatment
Experimental: Yoga-mindfulness
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).
Other: Yoga-mindfulness

Sample class:


(15 minutes) Standing poses

(15 minutes) Balance poses

(15 minutes) Abdominals & back bends (10 minutes) Cool-down

(5 minutes) Seated meditation Alternate nostril breathing Bellows breath Shoulder/neck stretches Cat-cow Forward fold Sun salutations Warrior 1 Warrior 2 Triangle Extended side angle Reverse warrior High lunge with twist Tree pose Standing holding knee Modified warrior 3 (chair support) Half moon

Bird-dog Side plank Bridge Cobra Sphinx Corpse pose Side-lying Seated om

Every month, a smudging ceremony will take place with an Aboriginal Elder for 5-10 minutes at the start of the class.

No Intervention: Control
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).

Primary Outcome Measures :
  1. B-CAM (Brief Cognitive Ability Measure) [ Time Frame: Will be assessed at baseline and 12 weeks. ]
    Cognitive function will be measured using the Brief Cognitive Ability (B-CAM), a computerized cognitive test developed using Rasch Measurement Theory and Analysis that takes 30 minutes to administer.

  2. C3Q (Communicating Cognitive Challenges in HIV Questionnaire) [ Time Frame: Will be assessed during screening, baseline, and 12 weeks. ]
    Self-reported cognition will be assessed using the C3Q (Communicating Cognitive Challenges in HIV Questionnaire).

Secondary Outcome Measures :
  1. Feasibility (Post-participation questionnaire) [ Time Frame: Assessed at 12 weeks. ]
    Many domains of feasibility will be assessed using a post-intervention questionnaire with questions related to participant comfort, satisfaction, safety, attendance, and time commitment.

  2. Balance [ Time Frame: Assessed at baseline and at 12 weeks. ]
    Balance will be measured using the Community Balance and Mobility test (CB&M).

  3. Walking Speed [ Time Frame: Assessed at baseline and at 12 weeks. ]
    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.

  4. Depression [ Time Frame: Assessed at baseline and at 12 weeks. ]
    Depression will be assessed using the Hospital Anxiety and Depression Scale, a self-report questionnaire.

  5. Medication Adherence [ Time Frame: Assessed at baseline and at 12 weeks. ]
    Participants will also be asked about Medication adherence (specifically antiretroviral) using the Simplified Medication Adherence Questionnaire (SMAQ).

  6. Health-related Quality of Life [ Time Frame: Assessed at baseline and at 12 weeks. ]
    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).
