Brief Summary

The overall objective of this research is to provide evidence on the effectiveness and implementation of two strategies deliver a structured programme of physical activity (PA) people living with HIV older than 50 years from Ivory Coast.

The research will starts a baseline formative research including people with and without HIV infection.

Participants are randomized 1:1:1 to one for the following group: (1) a reference arm receiving a group-based PA program supervised by a coach (n = 60), (2) an exploratory arm receiving a home-based PA program with remote supervision via phone calls and messaging apps (n = 60) and (3) a control arm receiving health education sessions (n = 60). The total follow-up period is 12 months, with an initial 6-month active phase and then a 6-month maintenance.

The primary effectiveness outcome is the improvement at the 6-minute step-up test between baseline and 6 months. Secondary outcomes include changes in performance on other functional tests and improvement of cardio-metabolic risk factors. Implementation outcomes include acceptability, adoption, feasibility and sustainability of the intervention.Implementation outcomes will be assessed using mixed methods during the intervention. Effectiveness outcomes and patient-centered outcomes will be assessed at baseline, 6 and 12 months.

Detailed Description

This is is a prospective, randomised, pilot trial with two phases: a 6-month active phase to implement the intervention and a 6-month maintenance phase to evaluate the sustainability of the intervention's effects. This study adopts a type II hybrid design assessing both the effectiveness of the intervention and the implementation outcomes to identify factors influencing its adoption by users, as well as its integration into healthcare practices

It starts with a baseline research combining a cross-sectional study and a qualitative formative research. The cross-sectional study comprises clinical evaluations, functional tests, as well as quantitative evaluations by questionnaire of disability (WHODAS, HDQ) and depression (PHQ-9). It includes 300 people living wiht HIV (PLHIV) receiving antiretroviral therapy and followed at the Avocatier health facility (FSU) and the El Rapha medical health centre (CMS), in the Abobo district, Abidjan. A comparison group of adults without HIV infection of similar sex and age distribution is included as a reference group (n = 150).

The qualitative research explores how the practice of physical activity is perceived culturally and socially and to determine the factors that may influence the implementation of this type of activity.

The intervention consists of a 48-week exercise programme including aerobic, resistance, balance and flexibility exercises twice to three times a week for at least 60 minutes. Two delivery approaches for the exercise programme are proposed. In the group-based arm, participants are invited to participate in group sessions directly supervised by a coach. The other sessions are unsupervised. During the first 24 weeks (active phase), the supervised group sessions are scheduled on a weekly basis while they are more spaced out, on a monthly basis, during the second part of the 48 weeks (maintenance phase). In the home-based arm, participants have to perform the same exercise programme at home. Participants are contacted by phone by a study staff every week to review the activities performed, collect information on their adherence to and perception of the programme and to provide positive feedback, help to addess challenges and reinforce their motivation. Participants of the control group are offered monthly health education sessions and a delayed participation to the programme.

Study Groups

Groupes-based arm

Participants are invited to participate in group sessions directly supervised by a coach. The other sessions are unsupervised. During the first 24 weeks (active phase), the supervised group sessions are scheduled on a weekly basis while they are more spaced out, on a monthly basis, during the second part of the 48 weeks (maintenance phase).

Group Type: EXPERIMENTAL

Physical activity programme

Intervention Type: BEHAVIORAL

48-week exercise programme including aerobic, resistance, balance and flexibility exercises twice to three times per week. The sessions are supervised by a coach at least once a week during the first 6 months then monthly. The other session of the PA programme is performed at home and the overall weekly PA is reviewed with the coach at the end of the supervised session.

Home-based arm

Participants have to perform the same exercise programme at home. Start with two weeks of direct supervision to learn how to carry out safely the training and how to adapt the intensity of the exercise using the rated perceived exertion (RPE) and the heart rate self-monitored during exercise.

Group Type: EXPERIMENTAL

Home-based physical activity

Intervention Type: BEHAVIORAL

48-week exercise programme including aerobic, resistance, balance and flexibility exercises twice to three times per week. Participants have to perform the exercise programme at home exclusively. They are called every week by a research assistant to review the activities performed, collect information on their adherence and perception on the programme.

Control arm

Health education session every months.

Group Type: NO_INTERVENTION

No interventions assigned to this group
