      Over the past 4 decades, the global prevalence of obesity (body mass index or BMI [calculated as weight (kg)/height (m2)] of 30) has increased dramatically.

      National, regional, and global trends in body-mass index since 1980: systematic analysis of health examination surveys and epidemiological studies with 960 country-years and 9.1 million participants.
      According to 2008 estimates from the World Health Organization, 500 million adults aged 20 or older in the world are obese and an additional 900 million are overweight (BMI of 25.0-29.9).

      World Health Organization. Obesity and Overweight. Fact Sheet 311. Updated March 2013. Available at: http://www.who.int/mediacentre/factsheets/fs311/en. Accessed September 24, 2013.

      Thus, 35% of all adults worldwide are overweight or obese, which represents a doubling of obesity rates since 1980.

      In men, obesity prevalence rates are highest in North America, Australasia, and Southern Latin America and in women, prevalence rates are greatest in Africa, North America, and the Middle East.
