Cost-effectiveness of a primary care based physical activity intervention in 45-74 year old men and women: a randomised controlled trial.

OBJECTIVE: To assess the cost-effectiveness of a primary care based intervention aimed at increasing levels of physical activity in inactive people aged 45-74. METHODS: A total of 714 inactive people aged 45-74, taken from two west London general practices, were randomised into two groups. Intervention subjects were invited to a consultation with an exercise development officer, and offered a personalised 10 week programme to increase their level of regular physical activity, combining leisure centre and home based activities. Control subjects were sent information on local leisure centres. All subjects were followed up at eight months. RESULTS: There was a net 10.6% (95% confidence interval 4.5 to 16.9%) reduction in the proportion of people classified as sedentary in the intervention group compared with the control group, eight months after the intervention. The intervention group also reported an increase in the mean number of episodes of physical activity per week, as compared with the control group (an additional 1.52 episodes (95% confidence interval 1.14 to 1.95)). The cost of moving a person out of the sedentary group was shown to be less than 650 Pounds. The cost of moving someone to the now commonly recommended level was estimated at almost 2500 Pounds. CONCLUSIONS: Moderate physical activity can be successfully encouraged in previously sedentary men and women aged 45-74 through a primary care based intervention. The process of recruitment was the most important variable cost. A high uptake rate would maximise cost-effectiveness, and sensitivity analysis suggests that unit costs could be halved with a more effective recruitment strategy.

Promoting physical activity: issues in primary health care.

In the past few years, alliances between primary care and leisure services have become a popular strategy for exercise promotion in the England. 'GP Referral Schemes' typically involve referral to a local leisure centre by a General Practitioner (GP), whereupon patients are inducted into a 10-12 week exercise programme at a reduced fee. Referred patients are usually white, middle aged and apparently healthy women, with the main reason for referral being overweight. The schemes are characterised by their lack of formal evaluation, making conclusions about effectiveness impossible. In the US, physicians advice to exercise has been the focus of interventions to date. Two controlled trials, one randomised, have provided some evidence that exercise behaviour can be changed, at least in the short term. The ability to recruit sufficient numbers of patients, who have potentially the most to gain from increased physical activity, is the biggest barrier to primary care based interventions. One contributing factor to this problem, may be doctors and nurses' knowledge about the benefits of physical activity.

Obesity management by life-style strategies.

This chapter discusses lifestyle management strategies for obesity in adults and is based on an assumption that treatment, resulting in appropriate and sustained weight loss, is of benefit to individuals. It examines dietary management strategies including the use of very low calorie diets, moderate energy restriction and individual and group approaches in commercial and non-commercial environments. It explores the role of physical activity in the treatment of obesity in particular focusing on the associated health benefits and the increasing evidence of the importance of physical activity in weight maintenance. It discusses the effect of behavioural interventions on achieving and maintaining weight loss and briefly offers suggestions for the organisation of lifestyle interventions.

A systematic review of physical activity promotion strategies.

We have reviewed randomised controlled trials of physical activity promotion to provide recent and reliable information on the effectiveness of physical activity promotion. Computerised databases and references of references were searched. Experts were contacted and asked for information about existing work. Studies assessed were randomised controlled trials of healthy, free living, adult subjects, where exercise behaviour was the dependent variable. Eleven trials were identified. No United Kingdom based studies were found. Interventions that encourage walking and do not require attendance at a facility are most likely to lead to sustainable increases in overall physical activity. Brisk walking has the greatest potential for increasing overall activity levels of a sedentary population and meeting current public health recommendations. The small number of trials limits the strength of any conclusions and highlights the need for more research.

Randomised controlled trials of physical activity promotion in free living populations: a review.

OBJECTIVES: To review evidence on the effectiveness of trials of physical activity promotion in healthy, free living adults. To identify the more effective intervention programmes. METHODS: Computerised databases and references were searched. Experts were contacted and asked for information about existing work. INCLUSION CRITERIA: Randomised controlled trials of healthy, free living adult subjects, where exercise behaviour was the dependent variable were included. CONCLUSIONS: Ten trials were identified. The small number of trials limits the strength of any conclusions and highlights the need for more research. No UK based studies were found. Previously sedentary adults can increase activity levels and sustain them. Promotion of these changes requires personal instruction, continued support, and exercise of moderate intensity which does not depend on attendance at a facility. The exercise should be easily included into an existing lifestyle and should be enjoyable. Walking is the exercise most likely to fulfil these criteria.
