Rates of obesity worldwide are continuing to rise and by 2025, 18 per cent of men and 21 per cent of women worldwide will be obese, according to a report published by The Lancet medical journal in the UK. The study, released on Thursday, covers individuals from nearly 200 countries and reveals an increase in the number of obese people from 105 million in 1975 to 641 million in 2014, adding that quick action is needed to avoid “an epidemic of severe obesity”.
More than one in 10 men and one in seven women are obese. It was also revealed that the world has more overweight than underweight people, according to an analysis of global trends in body mass index (BMI). “Over the past 40 years, we have changed from a world in which underweight prevalence was more than double that of obesity, to one in which more people are obese than underweight,” said senior author Professor Majid Ezzati from the School of Public Health at Imperial College London.
“The number of people across the globe whose weight poses a serious threat to their health is greater than ever before.” The study found that over the past four decades, the average age-corrected male BMI rose to 24.2 from 21.7, and in women rose to 24.4 from 22.1. This is equivalent to the world’s population becoming on average 1.5 kg heavier each decade, the researchers said.
Almost a fifth of the world’s obese adults live in six high-income countries: Australia, Canada, Ireland, New Zealand, Britain, and the US. Island nations in Polynesia and Micronesia have the highest average BMI in the world, while East Timor, Ethiopia, and Eritrea have the lowest average BMI.
