CREAL: World’s obese population hits 640 million, according to a study

News from CREAL

Researchers from CREAL, an ISGlobal allied centre, have participated in the largest study of obesity ever done in the world. It has estimated at more than 640 million people the total world population are suffering from obesity, the highest figure recorded in history. In this study more than 700 researchers were involved across the globe, who have collected and incorporated measurements of weight and height from nearly 20 million adults from 186 countries.

The study, led by scientists from Imperial College London and recently published in The Lancet, calculated and compared BMI among adult men and women from 1975 to 2014. The data revealed that in four decades global obesity among men has tripled - from 3.2% in 1975 to 10.8%. Obesity among women meanwhile has more than doubled, from 6.4 % in 1975 to 14.9% in 2014. This translates as 266 million obese men and 375 million obese women in the world in 2014. It also means the world’s population has become heavier by around 1.5kg in each subsequent decade since 1975.

The team predicted if these global trends continue, by 2025 18% of the world’s men and 21% of women will be obese. Furthermore, the probability of reaching the World Health Organization global obesity target (which aims for no rise in obesity above 2010 levels by 2025) will be close to zero.
