  6. Working out BMI Example: person weighing 80Kg who is 1.65m tall = BMI =29 kg/m2 =overweight 80kg / 2.72 (1.65m x1.65m)

  7. Adult weight in N.IrelandHSWB survey 2005/6

  8. Rates of overweight in children in N.I. • Almost 1 in 10 (8%) children aged 2-15 years is obese (NI Health and Social Wellbeing, 2006/07) Overweight and obesity in children was projected to rise but appears to have levelled off. • 22% of children entering P1 were either overweight or obese (5% of these obese) (Child Health System, 2004/05)

  9. What’s causing the obesity problem? Human biology combined with modern living

  10. Societal influences Individual psychology Individual activity Food Consumption Activity environment Food Production Biology
