One-third of world now overweight, with US leading the way
More than 2 billion adults and children globally are overweight or obese and suffer health problems because of their weight, a new study reports.
This equates to one-third of the world's population carrying excess weight, fueled by urbanization, poor diets and reduced physical activity.
The United States has the greatest percentage of obese children and young adults, at 13%, while Egypt led in terms of adult obesity, with almost 35%, among the 195 countries and territories included in the study.
While 2.2 billion people were obese or overweight in 2015, more than 710 million of them were classed as obese, with 5% of all children and 12% of adults fitting into this category.
An increasing number globally are dying from health problems linked to being overweight, such as cardiovascular disease, said the study, published Monday in the New England Journal of Medicine.
Almost 40% of the 4 million dying as a result of their higher body mass index were not yet obese, highlighting that deaths are occurring almost as often in those considered overweight as those considered obese.
Body mass index is the ratio between a person's weight and height; a BMI of 25 to 29.9 is considered overweight, while anything over 30 is obese.
"People who shrug off weight gain do so at their own risk -- risk of cardiovascular disease, diabetes, cancer, and other life-threatening conditions," said Dr. Christopher Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington, who worked on the study.
"Those half-serious New Year's resolutions to lose weight should become year-round commitments to lose weight and prevent future weight gain," he said in a statement.
The global obesity picture
The researchers analyzed data from 68.5 million people between 1980 and 2015 to explore trends as well as figures regarding overweight and obesity rates.
Data were obtained from the most recent Global Burden of Disease study, which explores all major diseases, conditions and injuries globally by age, sex and population.
The data revealed that the number of people affected by obesity has doubled since 1980 in 73 countries, and continued to rise across most other countries included in the analysis.
Obesity levels were higher among women than men across all age groups, which correlates with previous findings on obesity.
