Evaluating the Impact of the McMaster Optimal Aging Portal on Physical Mobility Outcomes

2016-10-28 05:53:21 | BioPortfolio


The McMaster Optimal Aging Portal (the Portal) was launched in 2014 to increase public access to trustworthy health information. The Portal helps readers to access evidence-based resources; identify trustworthy messages; and understand scientific findings. Now the investigators want to know whether using the Portal changes what people know and do to stay healthy and mobile.

This project will help us to:

1. Understand how middle aged and older adults (age 40+) use the Portal to obtain information about maintaining and improving mobility

2. Evaluate whether use of the Portal results in a change in knowledge about maintaining and improving mobility, or change in lifestyle behaviours that may help maintain or improve mobility with age.


Physically active lifestyles are important for health aging, but most Canadians do not meet published physical activity guidelines. This may be in part due to lack of access to evidence-based information on mobility and aging, and knowledge of strategies to maintain or improve mobility with age. The McMaster Optimal Aging Portal (the Portal) was launched in 2014 to increase public access to trustworthy health information. Now the investigators want to know if easy-to-understand evidence-based messages change what people know and do to stay healthy and mobile.

Sequential, explanatory mixed-methods design consisting of a two-armed randomized controlled trial and a qualitative process study to explore quantitative findings in depth.

Consent forms and a baseline survey will be sent to all interested participants. Following baseline data collection, participants will be stratified by previous Portal use, and randomized to the Knowledge Translation (KT) intervention or control group. During the 12-week KT intervention, intervention group participants will have access to the Portal and will receive mobility- focused weekly email alerts including blog posts and evidence summaries relevant to mobility and be invited to follow a Twitter and Facebook feed; a unique hashtag will be created to identify and collate relevant mobility information. Control group participants will be able to access the Portal in a 'self-serve' fashion, but will not receive targeted KT strategies.

Difficulty in walking from place to place.

An electrophoretic technique for assaying the binding of one compound to another. Typically one compound is labeled to follow its mobility during electrophoresis. If the labeled compound is bound by the other compound, then the mobility of the labeled compound through the electrophoretic medium will be retarded.

The upward or downward mobility in an occupation or the change from one occupation to another.

Patient health knowledge related to medications including what is being used and why as well as instructions and precautions.

A syndrome characterized by marked limitation of abduction of the eye, variable limitation of adduction and retraction of the globe, and narrowing of the palpebral fissure on attempted adduction. The condition is caused by aberrant innervation of the lateral rectus by fibers of the oculomotor nerve. There are three subtypes: type 1 (associated with loss of abduction), type 2 (associated with loss of adduction), and type 3 (loss of abduction and adduction). Two loci for Duane retraction syndrome have been located, one at chromosome 8q13 (DURS1) and another at chromosome 2q31(DURS2). It is usually caused by congenital hypoplasia of the abducens nerve or nucleus, but may rarely represent an acquired syndrome.
