About

Community walking is an issue that older adults with chronic conditions have described as important to participation in the community. Walking outside the home is a universally accessible form of physical activity that has multiple health benefits. Walking for 150 minutes per week can help reduce the risk of cardiovascular disease, hypertension, stroke, diabetes, osteoporosis, and depression, as well as falls. Practice walking across roads, slopes and curbs, while talking, and dealing with crowds and traffic, is safe and feasible and can improve confidence, balance and walking ability. Being physically active outdoors in nature appears to improve mental health more than being active indoors. Despite these health benefits, the majority of older Canadians do not walk outside on a regular basis. Barriers to walking outside include fear, physical disability due to chronic disease, the appropriateness of footwear and walking aids, and the physical environment, such as uneven pavement, weather and temperature. To date, the best strategy for getting people to walk outdoors regularly is unknown. The investigators propose to evaluate the effectiveness of a dynamic 1-day workshop, at which older adults who infrequently walk outdoors learn strategies to facilitate outdoor walking, such as appropriate use of footwear, ambulatory aids and equipment, goal setting, and practice skills related to increasing outdoor walking. The workshop will be compared to the workshop plus involvement in a walking group for 3 months. Outcomes include outdoor walking activity, total physical activity, walking ability, participation, and health-related quality of life. Each participant will have four evaluations: baseline, 3, 5.5 and 12 months later. The investigators will interview select participants at 6 and 12 months to ask them about their opinions of what worked and didn't work. Increasing outdoor walking is expected to improve health and well-being, and help people live independently in the community for longer.

Full description

Background: Inability to walk outdoors restricts full participation in physical activity and community living for older adults that can reduce health-related quality of life (HRQL). Older adults report limited outdoor walking with only 8% achieving the Canadian recommendation for older adults of 150 minutes of moderate-to-vigorous (MV) intensity physical activity per week. Known barriers to walking outside include fear, physical disability due to chronic disease, the appropriateness of footwear and walking aids, the physical environment, weather and temperature. Group practice walking outdoors in locations with variable environmental challenges has the potential to improve physical ability, confidence, outdoor and overall physical activity and social participation. The extent to which it is safe and feasible to implement this intervention in people with varying degrees of physical ability, preferences for where to walk, neighbourhood walkability, and to measure outdoor walking activity, is unclear.

Objectives: In older adults with a limitation in outdoor community mobility:

1. To estimate the extent to which a 1-day educational workshop and 10-week outdoor mobility program (GO-OUT intervention) compared to the workshop and weekly reminders improves outdoor walking activity (primary outcome) and secondary outcomes of physical activity, lifespace mobility, participation, HRQL, balance, leg strength, walking self-efficacy, walking speed, walking distance/endurance, and mood over 12 months.
2. To explore participants' perceptions of intended and unintended consequences of the interventions, potent intervention components, mechanisms of effect, modifying influences of disability level, sex,neighborhood walkability, weather, car access, and study site, and recommendations for future program delivery models.

Approaches and Methods:Study Design: A 2-group mixed methods stratified randomized controlled trial following CONSORT criteria is proposed. Group allocation will be concealed and outcome evaluation blinded. The trial will be run at 4 sites (Edmonton, Winnipeg, Toronto, Montreal) to accrue a sufficient sample size, optimize the external validity of the results to urban centres variable in population size, weather conditions, and environmental barriers, and build capacity across 4 provinces to support potential implementation. Following a baseline assessment, eligible participants will be stratified by site, and randomly assigned to receive the 1-day educational workshop and 3-month outdoor mobility program (GO-OUT intervention) or the 1-day workshop plus weekly reminders. Follow-up evaluations will occur at 3, 5.5 and 12 months from baseline. A sub-sample of participants from the GO-OUT and workshop groups at each site will participate in face-to-face interviews at 6 and 12 months to explore their experiences. Interventions and assessments are designed to be implemented in 'good weather' months, to avoid the potential negative effect of season on the primary outcome of outdoor walking activity.

Inclusion criteria

1. older adults defined as age 65 years or older;
2. living independently in the community;
3. ambulatory defined as self-reported ability to walk at least one block (~50 m) continuously on a flat surface with or without a walking aid and without supervision;
4. self-reported difficulty walking in the outdoor community environment (this could include physical impairments or decreased confidence);

7. available for a scheduled workshop and at least 5 of 10 weeks of the outdoor walking program; and
8. ability to speak and understand English

Exclusion criteria

1. physically active defined as self-reported participation in physical activities, such as walking and playing golf, 150 min per week;
2. currently receiving rehabilitation treatment, such as physical or occupational therapy, for goals related to walking (self-report);
3. at high falls risk defined by meeting one or more of the following American Geriatric Society criteria: (A) ≥2 falls in the last 12 months or presents with an acute fall; (B) cardiac, respiratory, peripheral vascular or other health conditions that would prevent safe and full participation in the interventions (self-report); (C) postural hypotension defined as a drop in systolic BP of >20 mm Hg or a drop in diastolic BP of >10 mm Hg taken after lying supine for 5 min and after standing for 2 min; (D) resting HR <45 or >100 beats per minute; and (E) severe limitation in visual acuity defined as self-reported difficulty reading the newspaper while wearing regular reading glasses or bifocals, or self-reported inability to distinguish a person's facial features from across a room while wearing glasses.

190 participants in 2 patient groups

GO-OUT Group

Experimental group

Description:

Participants attend 1-day walking workshop followed by a 3-month outdoor walking group intervention, twice weekly for 60-minutes. The same activities are completed during both sessions within the same week. Each session includes a 10-minute warm-up, a distance walk, practice of a specific outdoor walking skill, a distance walk, and a 10-minute cool down. The warm up and cool down include stretching, functional strengthening exercises and balance exercises taught during the workshop. The program incorporates the principles of task-specific training by emphasizing repetitive practice of progressively more difficult outdoor walking tasks. The outdoor walking program is conducted in one or more large park settings given the mental health benefits of exercising in a natural environment.

Other: GO-OUT Group

Workshop Group

Active Comparator group

Description:

The 1-day workshop will be 5 hours with breaks. Participants will complete a series of stations learning information, strategies and skills related to safely walking outdoors. Stations include: pedometer use; walking pole use; footwear; footcare; fall prevention; balance exercises; proper use of walking aids; correct posture; self-management of exercise intensity; goal setting; and walking safely outdoors. Participants will receive a workbook with Canadian Physical Activity Guidelines, benefits of outdoor walking, information for each workshop station and a pedometer. Participants will use the workbook as an information resource and to record their community ambulation goals, planning routes, and walking time. All participants will be encouraged to walk outside with a partner, for safety.
