Background and study aims
Sedentary behaviour (taking part in less than an hour a week of physical activity) is associated with an increased risk of heart disease, type 2 diabetes and some forms of cancer, as well as poorer mental wellbeing. It is a growing problem, and is thought to contribute significantly to the high levels of obesity worldwide. It is well known that physical activity (PA) is greatly beneficial to health. Despite this however, the PA levels of young people have been reported to be below the levels sufficient to gain the health benefits exercise can offer. Use of Internet to promote PA is a promising area but studies looking into its effectiveness have produced mixed results. The aim of this study is to examine the effectiveness of an internet-based physical activity promotion programme.
Who can participate?
Full time undergraduate students with a sedentary lifestyle.
What does the study involve?
Participants are randomly allocated to one of three groups. Those in the first group take part in an internet-based behaviour change program designed to promote PA. It is made up of 20 sessions which include reading material about the benefits of exercise and a workbook to complete. Those in the second group receive the same materials as the first group, but the sessions are delivered in weekly, hour-long, face-to-face group classes. Those in the third group continue as usual and do not take part in any behaviour change programs. At the start of the study and again after three and six months, all participants complete a number of questionnaires in order to find out if their physical activity levels have changed.
What are the possible benefits and risks of participating?
Participants may benefit from improving their levels of physical activity. There are no notable risks involved with participating in this study.
Where is the study run from?
The Chinese University of Hong Kong (China)

| Study objectives | Participants in the internet-based intervention group will demonstrate an improvement in physical activity participation to a similar extent as their counterparts in the face-to-face intervention group. |

| Intervention | Participants are stratified by gender and stage of behavior change before being randomly allocated via a computer-generated randomization sequence (GraphPad Software, Inc.) into one of the three groups by a statistician who was blinded to the intervention assignment. The participants were notified by e-mail about their randomization allocation. Internet-based intervention group: Participants are provided with a 20-session online behaviour change program entitled the Active Living Every Day (ALED) program. This involves read the program materials and to then complete the activities via the Internet at a convenient time and place at a rate of one session per week. A complimentary copy of the ALED workbook is provided with the online course. The program contents are designed for learning the behavior modification skills. Face-to-face intervention group: Participants receive the same information as the internet-based group but in a face-to-face class. They take part in weekly hour-long session for 14 weeks at a university. The discussion class is instructed by a licensed ALED facilitator and is also complemented by the ALED workbook. During the classes, cognitive and behavioral skills for adopting and maintaining an active lifestyle are discussed. Control group: Participants do not take part in any intervention and continue as usual for the duration of the study. Follow up involves sending online IPAQ and Stage of Change questionnaires three and six months after the commencement of the intervention to all participants. |
