The World Health Organization has described the rising prevalence of overweight (defined as body mass index [BMI] > 25 kg/m2) and obesity (BMI > 30 kg/m2) in developing and developed countries as a global pandemic. 1 Between 1980 and 2013, the proportion of women with a BMI of 25 kg/m2 or more increased worldwide from 29.8% (29.3–30.2) to 38.0% (37.5–38.5), and in at least seven countries including Kuwait, Libya, Qatar, and Samoa, the estimated prevalence of obesity in women now exceeds 50%. In developed countries, although the prevalence is much lower, the overall pattern and rise in rates of overweight and obesity parallels that of developing countries.
