The Global Problem of Obesity

BACKGROUND: In 2010, overweight and obesity were estimated to cause 3·4 million deaths, 3·9% of years of life lost, and 3·8% of disability-adjusted life-years (DALYs) worldwide.

METHODS: a systematic review was performed.

FINDINGS: Worldwide, the proportion of adults with a body-mass index (BMI) of 25 kg/m(2) or greater increased between 1980 and 2013 from 29% to 37% in men, and from 30% to 38% in women. In 2013 in developed countries, 24% of boys and 23% of girls were overweight or obese.

INTERPRETATION: obesity has become a major global health challenge. No national success stories have been reported in the past 33 years.
