MisterFIt: Multifaceted Intervention Using Telehealth to Reduce the Risk of Falls and Fractures in Older Men
Study Details
Study Description
Brief Summary
Men sustain over one-third of osteoporosis-related fractures worldwide. The burden of osteoporotic fractures in older men is substantial, and men suffer significantly worse fracture-related outcomes than women. Following a fracture, men sustain greater rates of subsequent fractures, loss of autonomy, and mortality than women and the imminent risk of re-fracture is several times higher in men than in women. Functional mobility, known to predict falls and fractures, is also notably worse in men following a fracture. In the fiscal year 2007-08, the overall annual costs of osteoporosis in Canadian men was evaluated to be $910 million.
Osteoporosis is primarily considered a disease of older women, and men are remarkably under-evaluated and under-treated for it. Recognition of sex and gender influences on skeletal health in men has been very slow; akin to the gap in cardiovascular diseases, where women are far less likely to receive guideline-recommended investigations and treatment.
Over 85% of Canadian men who suffer from fragility fractures do not receive osteoporosis screening and/or treatment strategies. The existence of this care gap in men underscores our current struggle to overcome important barriers including: 1) men's lack of awareness of the critical impact of osteoporosis and fractures on several aspects of their lives, and of the benefits of treatment; and 2) the absence of comprehensive and accessible treatments tailored to men.
Informed by the Knowledge-to-Action framework, we aim to address these barriers by adapting interventions with proven efficacy to engage men at high fracture risk in health behaviour change.
The current protocol is for a pilot RCT to determine the feasibility of recruitment and retention, adherence to, and acceptability of the virtually-delivered fracture prevention intervention only.
Our long-term goal is to conduct a large pragmatic randomized controlled trial (RCT) to address the research question: In older adults at high risk for fractures who self-identify as men, does anti-osteoporosis pharmacotherapy in conjunction with a virtually-delivered intervention that includes a gender-tailored strength training and balance based exercise program and nutritional counselling, improve functional mobility compared to anti-osteoporosis pharmacotherapy in conjunction with an attention control intervention.

Detailed Description
The current proposal for this assessor-blind parallel group multicenter pilot RCT of 12 months duration is in line with published frameworks for pilot studies in preparation for RCTs. For the pilot study, the investigators will enroll participants irrespective of anti-osteoporosis medication use.
This pilot RCT will determine the following primary feasibility objectives which will be assessed at 12 months :
-
Study recruitment rates: The study will be considered feasible if the investigators can recruit 12 participants per site within one year. Recruitment of 12 participants/site/year will translate to 360 participants with 10 sites over 3 years, which is the estimated sample size required for our future RCT with primary outcomes of physical function and fall rates, and secondary outcomes of bone strength.
-
Study retention rates: The study will be considered feasible if ≥ 75 % of the sample completes the 12-month assessment. This estimation is based on exercise RCTs where the attrition rate at 12 months ranged between 4% to 13% in community-based healthy men and up to 17% in frail older men.
-
Adherence to the exercise and nutrition interventions: The exercise intervention will be considered feasible if participants complete ≥ 65% of the prescribed number of exercise sessions at the 12-month follow-up. Beneficial effects of in-person supervised exercise on physical function in older men and women have been shown with a mean exercise session adherence of 60% at 12 months, and with a mean exercise session adherence of 63% in older men at 18 months. The nutrition intervention will be considered feasible if participants attend 66% of the visits.
-
Perceived usability of the telehealth platform application: via the System Usability Scale (SUS) where scores range from 0 (very poor) to 100 (excellent). Usability will be deemed to be acceptable if the mean SUS score is above 68 (SUS ≥ 68 = average user experience).
The investigators will also report exploratory analyses comparing the effect of the virtual intervention group to an attention control group. Exploratory outcomes will include the number of falls and fractures, changes in physical function (measured by lower extremity strength, gait speed, and balance), fall self-efficacy, quality of life and self-management behaviors in nutrition and exercise.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Misterfit online group The Misterfit online group will receive a 12-month virtually-delivered fracture prevention intervention that includes a personalized gender-tailored strength training and balance-based exercise program, nutritional counselling and fall and fracture prevention education. |
Behavioral: Multifaceted Virtual Fracture Prevention Program
Personalized exercise prescription: Comprised of muscle strengthening and balance exercises to perform three times a week, delivered and monitored remotely via the MisterFit app, a branded version of the secure commercially available Physiotec app (physiotec.com) and monthly virtual exercise consultations.
Virtual nutrition counseling from a registered dietitian in months 2, 4 and 6: to encourage participants to meet daily targets for calcium and vitamin D (preferably from diet), and protein intake to support muscle accretion and target weight maintenance
Virtual interactive information sessions in month 4 and 8: to education participants on topics identified as important by the Misterfit patient partner advisory committee.
|
| Other: MisterFit offline group The Misterfit offline group will act as an attention control group receiving a fracture prevention intervention with the same components as the experimental group, but the components will not be virtual, personalized or gender-tailored. |
Behavioral: Attention Control
Encouraged to meet the 24-Hour Movement Guidelines for adults aged 65 years or older (https://csepguidelines.ca) with telephone contacts at the same frequency that the Misterfit online group receives virtual exercise consultations
Nutritional fact sheets: sent by e-mail at the same frequency that the Misterfit online group meets with the research dietitian.
Educational fact sheets: sent by e-mail at the same frequency that the Misterfit Online group has virtual interactive information sessions
