The prevalence of obesity among adults has increased sharply during the 1990s and early 2000s. The proportion who were categorised as obese (BMI 30kg/m2 or over) increased from 13.2% of men in 1993 to 24.3% in 2014 and from 16.4% of women in 1993 to 26.8% in 2014 (Health Survey for England). In addition 9.5% of boys and 8.7% of girls (all children 9.1%) in Reception year (aged 4-5 years) and 20.7% of boys and 17.4% of girls (all children 19.1%) in Year 6 (aged 10-11 years) are also classified as obese according to the British 1990 population monitoring definition of obesity (≥95th centile) (National Child Measurement Programme 2014/15). By 2050 obesity is predicted to affect 60% of adult men, 50% of adult women and 25% of children (Foresight 2007).
In adults, obesity is commonly defined as a body mass index (BMI) of 30 or more. For children in the UK, the British 1990 growth reference charts are used to define weight status .
Obesity is associated with a range of health problems including type 2 diabetes, cardiovascular disease and cancer. The resulting NHS costs attributable to overweight and obesity are projected to reach £9.7 billion by 2050, with wider costs to society estimated to reach £49.9 billion per year (Foresight 2007). These factors combine to make the prevention of obesity a major public health challenge.
