Increasing prevalence of obesity in Australia and its possible effect on the occurrence of pulmonary thromboembolism

To the Editor: A recent study of adult bodyweights recorded in 199 countries showed an increase in mean body mass index (BMI) of 0.4 kg/m2 per decade between 1980 and 2008.1 The increase in Australia was even greater: 0.9 kg/m2 for men and 1.2 kg/m2 for women.1 This increase in BMI, sometimes referred to as an “obesity epidemic”, has also been reported in coronial cases in South Australia, with the percentage of morbidly obese individuals (BMI > 40 kg/m2) undergoing autopsy rising from 1.3% to 4.8% between 1986 and 2006.2
