The Welsh Obesity Society promote evidence based practice and working collaboratively to actively improve weight management treatment and prevention in Wales. We provide an expert multidisciplinary knowledge base and community on weight management in Wales and are passionate about improving the treatment and prevention of obesity. We have an active role in influencing decision making and policy around weight management in Wales and provide an expert, evidence base voice in the media.

The WOS advocates the use of the All Wales Obesity Pathway. This was produced by the Welsh Government in 2010 as a best practice document and guideline. It describes 4 tiers of intervention that health boards are required to have in place for children and adults.

These include:

  • level 1: community based prevention and early intervention
  • level 2: community and primary care weight management services
  • level 3: specialist multi-disciplinary team weight management services
  • level 4: specialist medical and surgical service

A level 3 service specification and access criteria for specialist multi-disciplinary team weight management services clarifies the minimum service requirements for developing services for adults in Wales.

In addition, a level 3 service specification and access criteria for specialist multi-disciplinary team weight management services for children and young people is under development.

There have been criticisms that the Obesity Pathway has not been fully implemented and there is a lack of Level 3 services, as well as calls for a clearer national direction on tackling obesity
