The past 20 years has seen a doubling in the worldwide prevalen
ce of morbid obesity (usually defined as a body mass index BMI, >40?kg/m
2). S
cotland has one of the worst obesity re
cords amongst developed
countries. In 2010, 65.1 % of all adults aged 16 and over were overweight or obese. Morbid obesity rates (BMI 40?kg/m
2 or more) in
creased from 1.2 % in 1995 to 2.7 % in 2003, and flu
ctuated between 2.2 % and 2.7 % between 2008 and 2010 ().
Morbid obesity is associated with twice the mortality compared with the general population. The National Audit Office (NAO) estimated that in 1998 over 30,000 deaths a year in England were attributable to obesity, approximately 6 % of all deaths in that year. Obesity is associated and with other conditions such as hypertension, type 2 diabetes, cardiovascular disease, osteoarthritis and cancer, as well as increased rates of psychiatric illness.
