Study hypothesis
|
Walking has been identified as an ideal mode of exercise to promote physical activity in the general population. Large knowledge gaps exist on the optimum methods to promote and sustain walking behaviour in a community setting. Following the RE-AIM principles, WWW is investigating whether a pedometer-based walking programme, in combination with a physical activity consultation will help community dwelling low active adults achieve and sustain the physical activity recommendation of 30 minutes of activity at least 5 days of the week. The study has six key research components (behavioural, psychological, environmental, physiological, qualitative and economic) allowing an insight into the complex relationships between behavioural change, health consequences and the role of the environment, along with participants' views and experiences and the cost effectiveness of this approach.
Research question:
Can a pedometer-based walking programme, in combination with a physical activity consultation increase and maintain walking behaviour over a 12 month period?

Interventions
|
Participants were randomised into one of two groups: immediate intervention (Group 1) or waiting list control (Group 2).
Participants randomised to Group 1 received a 30 minute physical activity consultation with a trained member of the research team. The participant was given an individualised 12-week walking programme and a pedometer. Following the 12-week walking programme, the participants received a second individual physical activity consultation focusing on relapse prevention. Participants received a written physical activity advice leaflet at 24 weeks and a telephone consultation at 36 weeks.
Participants randomised to Group 2 were allocated to a 12 week waiting list and were requested not to amend their current physical activity levels. After 12 weeks Group 2 received an individualised 12 week walking programme identical to Group 1, brief advice and a pedometer but did not receive a physical activity consultation (i.e., the waiting list control group then became a minimal intervention group).
At 24 weeks and 36 weeks participants received a short feedback session.

Primary outcome measure(s)
|
Walking behaviour: pedometer step counts (Omron HJ-109E Step-O-Meter).
Timepoints of measurement:
Intervention group - at baseline, 3, 6 and 12 months
Control group - at baseline, 3, 6, 9 and 15 months
|
|
Secondary outcome measure(s)
|
1. Walking behaviour: seven-day recall of physical activity using the International Physical Activity Questionnaire (IPAQ) (long version, self-report). This will be assessed at baseline, 3 , 6 and 12 months (intervention) and at baseline, 3, 6, 9 and 15 months (control).
2. Psychological: the four constructs of the Transtheoretical Model (stages of change, processes of change, self efficacy, and decisional balance questionnaires), along with mood (Positive and Negative Affect Schedule [PANAS] questionnaires) and quality of life (European Quality of Life [EQ-5D] questionnaires). This will be assessed at baseline, 12, 24 and 48 weeks (intervention) and at baseline, 12, 24, 36 and 60 weeks (control).
3. Physiological: Body composition, blood pressure, heart rate, total cholesterol, high density lipoprotein (HDL) cholesterol, insulin and glucose, and circulating levels of inflammatory markers. For the intervention group, all physiological measures were taken at baseline and 12 weeks. At 24 weeks body mass, body mass index (BMI), waist-to-hip ratio, percentage body fat, blood pressure and heart rate were assessed. In the control group, all physiological measures were assessed at baseline, 12 week and 24 weeks. At 36 weeks body mass, BMI, waist-to-hip ratio, percentage body fat, blood pressure and heart rate were assessed.
4. Environmental: perceived (subjective) environmental barriers or facilitators to activity, and also any changes in physical activity levels and environmental perceptions over the course of the study using the Neighbourhood Quality of Life Study (1st Survey; NQLS). Questionnaires were completed at baseline, 12 weeks, 24 weeks and 48 weeks (interverntion) and at baseline, 12 weeks, 24 weeks, 36 weeks and 60 weeks (control). An environmental audit tool and geographic information system (GIS) data provides an objective assessment of the study area in relation to walking.
5. Qualitative: a qualitative evaluation is being undertaken alongside the main randomised controlled trial to understand the social context of the trial
6. Economic: A health economist is economically evaluating the trial to give cost-effectiveness in terms of cost/quality-adjusted life years (QALY) gained and the cost per individual achieving the target (30 minutes of exercise on 5 days/week)
