  • Expert Consensus Meeting
  • No evidence of any effective intervention
  • BMI as a monitoring tool
  • BMI at 5y and 11y

10
Management
  • Degree of overweight
  • Age
  • Co-morbidities

Family based approach Family structure and social
support

Summary
  • Interventions could be considered at these
    levels
  • The treatment of individuals who identify
    themselves as obese and request help
  • Seeking individuals who are at risk, offering
    interventions
  • Offering interventions to whole communities eg
    schools which attempt to change the health
    behaviours of individuals within those
    communities

17
For Discussion
  • Local Care Pathways
  • Primary Care Setting
  • Specialist service for severe obesity
  • Available national guidance

  • Scottish Intercollegiate Guidelines Network
    (SIGN)
  • National Obesity Forum

Health benefits of losing weight Is it worth it?
  • 10 loss of weight in a100kg obese person with
    other diseases such as coronary heart disease or
    diabetes
  • Fall in more than 20 overall mortality
  • Fall of 10mmHg in diastolic systolic blood
    pressure
  • Fall of 10 of total cholesterol
  • Fall of 30 triglycerides
  • Fall of 50 in fasting glucose levels
  • As body weight increases, so does the risk of
    dying as a result

Child Obesity Data for Year 6 Pupils2005 - 2006
As a percentage of all children on school
roll As a percentage of all children measured
21
Levels of even light physical activity are low in
the City. As light physical activity is more
likely to be done regularly, initiatives to
encourage the population to be more active should
focus on activities at this intensity level, eg
walking.
