Obesity
1 in 3 people who were classified as normal weight in 1994-1995 had become overweight by 2002-2003. And nearly 1 in 4 people who were initially overweight were classified as obese after the eight-year period. Conversely, only 10% of those who were overweight in 1994-1995 had progressed to a normal weight range by 2002-2003.
