Brief Summary

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 three evaluations: before the intervention and 3 and 6 months later. The investigators will interview select participants at 6 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.

Detailed 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: The study purpose is to evaluate the feasibility of a randomized controlled trial (RCT) protocol designed to evaluate the effectiveness of an education and skills workshop plus a 3-month outdoor walking group (GO-OUT program) compared to the workshop alone in improving outdoor walking activity. Specific objectives are to characterize participants; determine the feasibility of recruitment; estimate withdrawal rates and the safety and feasibility of the study protocol; obtain preliminary effect sizes; identify the optimal measure of outdoor walking activity based on validity, reliability, effect size and data completeness; and identify participants' and intervention facilitators' perceptions of the challenges and benefits of the intervention and evaluation tools.

Methods: Design and Participants-A feasibility RCT with an embedded qualitative component is proposed with 18 participants. Ambulatory older adults living in the community who report walking outdoors ≤20 minutes/week will be stratified by level of walking impairment (gait speed\<0.8 m/s vs ≥0.8 m/s) and randomly assigned to receive the GO-OUT program or the workshop alone. Group allocation will be concealed. A blinded evaluator will evaluate participants at baseline, 3 and 6 months. At 6 months, focus groups of participants from the GO-OUT and workshop groups and intervention facilitators, will participate in a semi-structured interview to explore perceived benefits and challenges of adherence, intervention strategy and outcome measures. Interventions-The workshop will include activity stations at which people will learn about appropriate footwear, walking aids and equipment (pedometers, Nordic poles), goal setting, physical activity recommendations/benefits and practice walking-related tasks. The GO-OUT program will include the workshop plus the outdoor walking group. The walking group will be supervised and consist of 9 participants; they will meet twice a week for 1 hour to walk in increasingly challenging environments to achieve individualized goals. Outcome Measures-Outdoor walking (primary outcome) will be measured by 2 methods: outdoor walking items of the Community Health Activities Model Program for Seniors (CHAMPS) (self-report) and accelerometer/Global Positioning System (GPS). Overall physical activity (secondary outcome) will be measured with the CHAMPS (self-report) as well as accelerometry. Measures of aerobic capacity, walking competency, mood, participation, and HRQL will also be administered. Neighbourhood walkability will be assessed with the Neighbourhood Environment Walkability Scale (self-report). Analysis-This is a feasibility study; therefore, no hypotheses will be tested. The analysis will include describing participant characteristics, estimating recruitment, withdrawal and adverse event rates, estimating preliminary effect sizes for outcome measures, estimating test-retest reliability of outdoor walk time derived from the CHAMPS and construct validity and data completeness of outdoor walk time derived from the CHAMPS and accelerometry/GPS. A qualitative descriptive approach will be used to analyse the interview data. Conclusion-Increasing outdoor walking is expected to help people improve physical activity, the ability to live independently in the community, and health and well-being. This study will evaluate the feasibility of a trial protocol aimed at improving outdoor walking. Findings will be used to justify and inform planning of a future definitive multi-site trial.
