Amanda's primary research focuses on weight (obesity) management in primary care.

In the UK, 25% of adults are obese and the prevalence is projected to double over the next 50 years. It is a major cause of morbidity and chronic disease, particularly increasing the risk of type II diabetes, cardiovascular disease and some cancers. Furthermore, the direct cost in England is estimated at £4.2 billion per year.

Despite the substantial health and financial implications, no NHS treatment service for obesity exists and general practitioners (GPs) rarely discuss weight management with patients or support behaviour change. Evidence demonstrates the effectiveness of brief, opportunistic interventions by GPs for tobacco control and problem drinking. No trial, however, has examined whether screening to identify overweight or obesity in adults and brief intervention are effective. Therefore we are conducting a randomised controlled trial to examine the effectiveness of a brief opportunistic intervention for weight management and the active engagement of GPs in supporting weight loss, in obese adults in primary care; the BWeL trial (Brief intervention for Weight Loss).

The results of the trial could make the case for brief interventions for obese people consulting with their GP and introduce widespread simple treatments akin to the NHS Stop Smoking Service. If successful, the intervention could also be introduced in the Quality and Outcomes Framework and influence weight management practice worldwide.

Besides BWeL, Amanda is involved with research about preventing weight gain during pregnancy and the use of attentive eating strategies to lose or maintain weight. Furthermore, she co-supervises a PhD student who is exploring different cognitive and behavioural approaches to weight control, in particular regular weighing and self monitoring techniques.

She is very keen to explore new research about health behaviour change, in particular the relationship between weight management (both under- and overweight) and health conditions such as arthritis, back pain and diabetes.
