Plain English Summary

Background and study aims
The physical activity levels of adults with intellectual disabilities reported in previous research studies were below the recommended level to keep healthy. Not much is known about how best to support adults with intellectual disabilities to be more active. Walking is a sustainable form of physical activity that can be incorporated into everyday life. Interventions that support people to walk more have been shown to lead to improved health and wellbeing. This study will examine whether a walking intervention helps adults with intellectual disabilities increase how much walking they do and improves their health.

Who can participate?
Adults with intellectual disabilities between 18 and 65 years of age, living in the catchment area of NHS Greater Glasgow and Clyde can take part in this study. Potential participants should be able to walk for 10 minutes.

What does the study involve?
Before the walking program (intervention) starts, participants will be invited to meet with a researcher. The researcher will ask participants questions about current levels of physical activity and health. We would also like to ask carers some questions. We would also like to measure physical activity by asking participants to wear a belt round the waist. The belt has a small box attached called an accelerometer that measures physical activity and how many steps the wearer takes. Participants will also be invited to have their height, weight and waist circumference measured. These measurements will be repeated after the individual takes part in the walking intervention. The walking intervention lasts 12 weeks. Participants will meet with a walking coordinator three times. The walking coordinator will talk to participants and carers about physical activity and walking. With the help of the walking coordinator, participants will choose an individualised walking program to follow. The aim of the walking program is to help participants increase the time they spend walking gradually over the 12 week intervention period. At the end of the walking intervention we will ask participants and carers to tell us what they think about the intervention.

What are the possible benefits and risks of participating?
Participants may experience health benefits by taking part in the intervention. They may also become more confident about taking part in physical activity. We do not anticipate any significant risks for participants.

Study information

Scientific title

The impact of a walking intervention on the physical activity levels and health of adults with intellectual disabilities: a randomised controlled trial


Study hypothesis

1. Does a 12-week walking intervention for adults with intellectual disabilities increase the average number of steps walked per day?
2. Does a walking intervention for adults with intellectual disabilities increase the average time spent per day in moderate-vigorous intensity?
3. Does a walking intervention for adults with intellectual disabilities reduce time spent on sedentary behaviour?
4. Are changes in walking behaviours, physical activity and sedentary behaviour maintained at follow-up, three months after the end of the walking intervention?
5. Does a walking intervention for adults with intellectual disabilities lead to improved wellbeing and self efficacy for physical activity?
6. How do individuals with learning disabilities who have participated in a walking intervention view the experience?
