Physical activity is good for older adults.

Two seniors pondering what physical activities they could do. There is a thought bubble. One senior has a ball, the other has weights. There are question marks. There is an Active Aging Research Team logo.

Public health messages are clear — we all need to add more physical activity into our lives. As we age, this message focuses on physical activity to keep us healthy, and hopefully prevent catastrophic health events. I am a PhD student focused on the promotion of healthy aging at the population level. I know of many (many) studies of physical activity programs designed specifically to help older people prevent falls, stay mobile and independent, prevent chronic disease, and a host of other stuff that ostensibly improves health.¹,²,³ What I am learning now is that most of these effective physical activity programs NEVER make it out into the real world. They are primarily one-off studies conducted by researchers in academic ivory towers. How then can they actually help older people? So, I set out to answer this question:

If an effective intervention never leaves a controlled research environment, is it truly effective?

Like the old adage, I often wonder if effective interventions never leave the research environment, are they effective?

To answer this daunting question, I delved into a field of academic study called Implementation Science. Simply speaking, Implementation Science is the study of taking effective health innovations and learning how best to help people/organizations in vastly different places deliver (e.g., implement) those innovations to more and more different groups of people.⁴,⁵ Learn more here. To illustrate — say I want to know if I can successfully implement an effective chair fitness class (let’s call it ‘Get Fit while I Sit’) to older adults who live in three different regions of Canada. The implementation scientist in me will ask questions ⁶ at a couple of levels. First, I want to know;

· Do those delivering ‘Get Fit while I Sit’ have the resources, training, and skills they need to implement effectively? [capacity]

· Are implementation strategies acceptable, feasible, appropriate to organizations that are going to deliver ‘Get Fit while I Sit’ to their members and for the different regions where classes will be delivered?

I also would want to know;

· How much of ‘Get Fit while I Sit’ was delivered by the chair fitness instructor? [Dose delivered]

· How well did the instructor deliver it? [Quality]

· How widely was it delivered? [Reach]

Capacity. Implementation strategies. Dosed delivered. Quality. Reach. Circles with images for each item.

Armed with implementation science principles, I plunged into the scientific literature. My mission: to find out just how many of these great physical activity programs evaluated the questions I posed above. I searched for:

· any indicators (measures) of how the program was implemented;

· the number of programs that were guided by frameworks within the implementation science field; and

· the number of programs that achieved widespread delivery (scaled-up) and were broadly accessible to older people.

Indcators (measures). Frameworks-guided programs. Widespread delivery and accessibility.

With some (lots of) help from my colleagues, I took a rigorous and systematic approach.⁷ Our team screened more than 2400 published papers that described physical activity and exercise programs that were designed and implemented for community-dwelling older adults. We narrowed this pool down to 159 publications, representing 137 unique studies, that met our *criteria.

So how many of these studies actually reported at least one indicator of implementation? [Drum roll] Only 15–20%. The most common indicator assessed in these studies was ‘dose received’. Dose received measured attendance at the program or compliance with the program (reported in 114 studies; 83%). Only 8% of studies were guided by an implementation framework (defined as ‘a structure, overview, or outline of various concepts or variables and the relations between them that are presumed to account for a phenomenon’).⁸ This is a little dismal, considering that there are more than 60 published frameworks to guide researchers on how to deliver effective programs successfully and at scale.⁹ Finally, only 6 studies (4%) had what could be considered widespread delivery (were scaled-up). A disappointing finding indeed. I was dismayed that vastly more resources are invested in developing ‘one-off’ innovations (interventions/programs/practices) than are invested in discerning how to deliver them effectively and broadly so that they can benefit a larger number of people.

Did I answer my question ‘do older adults have easy access to programs that keep them active?’ In short, yes I did. There are tons of effective physical activity programs out there for older adults. But few make it out of controlled research settings and into the community where they can be delivered to and easily accessed by older adults. But, there is a way forward and I would be remiss if I did not conjure up the words of Stephen Covey ‘begin with the end in mind’. I defer also to the World Health Organization that recommends that from the start we build health initiatives that can be easily scaled-up so that they reach more people in more places. Initiatives must also be designed to be readily adaptable to diverse contexts and communities.¹⁰ As researchers we can only get this done if we work closely with key community partners who are familiar with the places (and the people) where we wish to launch our program. In a nutshell, it is time to sort out widespread delivery — how best to scale-up — effective programs so that more older adults access them to keep moving and grooving.
