ClinicalTrials.gov identifier
EudraCT number
Public title Improving physical activity among older adults with intellectual disabilities by a structured day care program
Scientific title Improving physical activity among older adults with a mild or moderate intellectual disability by a structured day care program: a cluster randomized trial
Acronym IPAD-ID
Serial number at source 57000003 / 62-614000-98-006_02
Study hypothesis The physical activity level of participants will improve, whereas the physical activity level of the control group remains on the same (low) level.
The physical fitness level of participants will remain equal or will improve a little, whereas the physical fitness level of the control group remains equal or declines. This hypothesis is also applicable to the secondary outcome measures.
Lay summary Background and study aims:
The aim of our study is to improve the physical activity level in seniors with an intellectual disability. Regular physical activity is very important to their health and is specifically important for the prevention and reduction of falls and functional limitations. We developed a new physical activity program and we determined if it indeed improved the physical activity and health of the seniors.

Who can participate?
People with a mild or moderate intellectual disability, aged 45 years and older.

What does the study involve?
The physical activity program will be conducted in the participantsí day care centers. Day care centers will be randomly allocated to participate in the program or serve as a control group. Those who participate in the study will be divided into two groups. One group will conduct the physical activity program for eight months, three times a week. The program includes education about the importance of physical activity to their health and performing physical activities.
The other group will conduct normal activities at the day care center as usual; there will be no changes in their daily program.

What are the possible benefits and risks of participating?
Participants will learn about the importance of physical activity and increase their self-confidence and enjoyment in participating in physical activities. Participants who will actively perform the physical activities, will become more healthy and their fitness may increase and they will feel more flexible and fit. Before the program starts, the general practitioner will be asked to provide a medical advice about participating safely. If no positive advice is provided, the participant cannot continue in the program. Heart-rate monitors will be used to evaluate the heart-rate changes during the activities. If there are falls or other undesirable situations, the researcher, the conductors and physical therapist and or the general practitioner will discuss the continuation of the program.

Where is the study run from?
Ipse de Bruggen and Amarant en Abrona

When is study starting and how long is it expected to run for?
The study started in March 2010 and the last health measurements were taken in October 2011.
