Study: Major Rise in Global Obesity, Bad News for Cancer Prevention

A major global report was released today on obesity and the news is grim. The numbers of overweight and obese people around the world have increased dramatically since 1980, in both developing and developed countries and among all age groups, with the United States accounting for 13 percent of the world’s obesity.obesity-and-cancer

The report was published today in The Lancet.

The findings bode ill for cancer prevention: aside from smoking, obesity is the single largest risk factor for cancer. AICR estimates that obesity is a cause of eight cancers, including postmenopausal breast, colorectal and ovarian. Obesity also plays a major role in other chronic disease, such as type 2 diabetes, which also links to increased cancer risk.

The study included data from over 180 countries. Study researchers systematically identified surveys, reports, and studies that provided Body Mass Index data. A BMI of 25 and over is categorized as overweight; 30 and over is obese.

The Lancet report estimates that worldwide, the proportion of adults with a BMI of 25 or greater increased between 1980 and 2013 from 29 percent to 37 percent in men, and from 30 percent to 38 percent in women. Continue reading


Preventing 2.8 Million Cancers

Every year, two out of every three people die from diseases called non-communicable – abbreviated as NCDs – which we know of as heart disease, diabetes, strokes, and cancer.

NCDs kill 9 million people under the age of 60 annually. And 90 percent of NCD cases occur in the developing world.

For cancer, the number of annual cases stands at 12 million. Approximately 2.8 million of these cancers are preventable through diet, exercise, and weight management, according to new estimates released by AICR and its partners in the World Cancer Research Fund global network.

On September 19 and 20, the United Nations (UN) will hold a Summit on NCDs in what is only the second time in the UN’s history that a health issue is receiving such high levels of global attention. (The last issue was AIDS.)
