Plain English Summary
Background and study aims
Studies have shown that increasing physical activity levels, especially through increasing walking, can protect older people from developing mobility loss. Increasing physical activity can also reduce the risk of diseases like obesity, diabetes, stroke, heart problems, osteoporosis, depression and Alzheimer’s disease. It is not known which way is the best to change people’s behaviour and help them to become more active. The aim of this study is to see whether simple measures including advice about how to increase activity levels and setting out an activity plan will help people increase their physical activity. The study will also check if using a pedometer (a small device that is worn around the neck or at the waistband that counts the number of steps taken) to set targets will help people further increase their activity levels.
Who can participate?
Women aged 70 or over who are insufficiently active or sedentary
What does the study involve?
The study lasts for 6 months during which time the study nurse and research assistant will arrange to visit participants at home on five occasions. Participants are randomly allocated to one of three groups. Participants in the first group are asked to wear a pedometer for 6 months and to fill in a daily activity diary. They are also given advice on how to increase their physical activity levels and an activity plan designed to suit their needs. Participants in the second group are given the advice and activity plan only. Participants in the third group receive nothing. At the beginning of the study, the middle and again at the end of the study 6 months later, all participants undergo a walking test, a balance test, and a standing and sitting down test, and complete four questionnaires about how well they feel, how often they need to attend their GP surgery, their mood, and how well they have managed to follow their ‘Activity Plan’. These take about ten minutes to complete with the research assistant. Participants keep a record of any falls and what might have caused these. Participants who receive a pedometer are asked to walk 100 steps to check whether the pedometer works best worn on the waistband or around the neck. They are also asked to keep a record of the number of steps recorded each day on the pedometer. They are encouraged to gradually increase the number of steps they take every day. At the end of the study they are allowed to keep the pedometers for their own use. Irrespective of whether or not they are asked to wear a pedometer, all the women in the study are asked to wear a second device called an accelerometer on three occasions for periods of one week during the first, middle and last weeks of the study. The accelerometer is a small device about the size and shape of a small matchbox which tells us about their overall total activity. Participants have five home visits over the course of the study that last about 40 minutes each, two visits from the study nurse and three from the research assistant. Between the first and last visit, the study nurse contacts them by telephone to find out about how they are managing with their activity plan. For the first month they contact them every week and for the rest of the study they telephone fortnightly.
What are the possible benefits and risks of participating?
Increasing physical activity levels, especially through increasing walking, can protect older people from developing mobility loss. Increasing physical activity can also reduce the risk of diseases like obesity, diabetes, stroke heart problems, osteoporosis, depression and Alzheimer’s disease. It is hoped that the physical activity advice will prove beneficial. This study aims at increasing physical activity levels. Too rapid an increase can lead to mild tiredness. Participants are encouraged to increase their physical activity levels gradually and appropriate targets are set.

Sedentary women over 70 years of age
The participants will be randomised to one of the following 3 arms:
Arm 1: Advice and pedometer
Arm 2: Advice only
Arm 3: Control group
Arms 1 and 2 receive tailored advice at the baseline session from a nurse visiting the participant at home. They will be encouraged to incorporate more walking into their daily routine. They will be given monthly targets to achieve (in pedometer counts for Arm 1 and in time spent walking outdoors for Arm 2). Both arms will be given daily activity diaries to complete (of pedometer count for Arm 1 and of time spent walking outdoors for Arm 2). They will receive telephone support weekly for the first month then fortnightly thereafter. The control group receives no intervention.
Primary outcome measure
Change in daily activity levels by accelerometry
Secondary outcome measures
The following will be assessed at baseline, 3 and 6 months:
1. Lower limb function (a validated 12-point performance score)
2. Health related quality of life (the Euroquol questionnaire)
3. Depression (the Hospital Anxiety and Depression Scale ([HADS])
Overall trial start date
Overall trial end date
Reason abandoned (if study stopped)
Participant inclusion criteria
1. Women aged 70 years or over
2. Insufficiently active or sedentary (no participation in moderate-intensity physical activity of at least 30 minutes at least 5 days per week, or at least 20 minutes of continuous vigorous-intensity activity 3 or more times per week)
Target number of participants
Participant exclusion criteria
1. Women fulfilling recommended physical activity recommendations
2. Resident of institutional care
3. Housebound (so unable to increase outdoor walking)
4. Moderate to severe cognitive impairment precluding informed consent
5. Visually impaired (unable to read pedometer count)
6. Wheelchair bound
7. Unwilling to participate
