Management of obesity in Scotland: development of the latest evidence-based recommendations.

The problem of obesity in Scotland has reached epidemic proportions and this reality is recognised at Scottish Government level. The financial impact of treating obesity and obesity-related disease is substantial and in Scotland the cost was estimated at pound171 x 10(6) in 2001 but only a small proportion of this estimate included weight-loss interventions. The Scottish Intercollegiate Guidelines Network (SIGN) define clinical guidelines as 'systematically developed statements to help practitioner and patient decisions' that 'provide recommendations for effective practice in the management of clinical conditions where variations in practice are known to occur and where effective care may be known not to occur'. The evidence base for successful interventions has progressed since the publication by SIGN of Obesity in Scotland: Integrating Prevention with Weight Management in 1996 and Management of Obesity in Children and Young People in 2003. In 2007 SIGN commissioned a review of these two publications. In 2006 the National Institute for Health and Clinical Excellence (NICE) published a comprehensive obesity guideline and to avoid duplication of effort SIGN used the ADAPTE guideline adaptation framework to utilise and update evidence tables produced by NICE (where appropriate) as a basis for considered judgement. The new SIGN guideline is due for publication in 2010 and addresses children, young people (<18 years old) and adults. It will provide evidence-based recommendations on primary prevention of obesity (defined as intervention when individuals are at a healthy weight and/or overweight to prevent or delay the onset of obesity) within the clinical setting and treatment by lifestyle measures, drugs and surgery.
