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


Report: Behavior Changes Can Prevent Deaths from Cancer and Other Leading Causes

Eating healthy, exercising and being a healthy weight are among the behavior changes Americans can make to cut 20 to 40 percent of the five leading causes of US deaths, including cancer, according to a new report from the Centers from Disease Control and Prevention. For cancer, not smoking or drinking alcohol also play a key role in preventing deaths.Preventable2

The report highlights how the same factors that reduce the risk of cancer also reduce the risk of other diseases. (We talk here about Eating to Prevent Heart Disease and Cancer the two leading causes of death.)

According to the report, the five leading causes of death in the United States are heart disease, cancer, chronic lower respiratory diseases, stroke, and unintentional injuries.

The CDC report focused on premature deaths. Together, the five leading causes of death accounted for almost two-thirds of all U.S. deaths in 2010. State by state, the report looked at mortality data from 2008-2010 of those who died before age 80. They then used the state with the lowest numbers of deaths as the benchmark to calculate the numbers of deaths from each cause that could be prevented in each state. Continue reading


Your County’s Health and Cancer Risk

The latest report on county health rankings found, once again, where you live makes a  difference to how long you live and your health. The least healthy counties have twice the death rates as the nation’s healthiest, according to the report. Wepeople_03

This is the fifth annual County Health Rankings, a report that compiles data on mortality and 29 health factors, including many that relate to cancer risk. For these factors, the findings are slightly encouraging for the nation. These include:

  • Obesity: Obesity rates for adults are holding steady with a rate of 28 percent for 2012. Prior, obesity rates increased from 16 percent of adults in 1995 to 28 percent in 2010. Aside from smoking, obesity is now the single largest risk factor for cancer. The latest research shows that obesity is a cause of 8 cancers, including post-menopausal breast, ovarian and endometrial. Continue reading
