There’s been some controversy about whether being overweight, but not obese, might actually link to a longer life. A few years ago a major study suggested that paradox. We wrote about it here.
For lower cancer risk, healthy weight is key. AICR’s reports find that overweight and obesity increase risk for 11 cancers, including colorectal and postmenopausal breast.
In this new analysis on weight and mortality, researchers used a person’s highest weight during the study and found that those who were overweight or obese had increased risk for early death. The data comes from 225,000 participants in the Nurses Health Studies (NHS I and II) and the Health Professionals Follow-Up Study (HPFS). It was published last week in the Annals of Internal Medicine.
According to a recent study, fewer US adults with overweight or obesity are trying to lose weight in what is a concerning trend for cancer prevention. With obesity rates increasing and fewer at a healthy weight, more people will be at risk for several cancers such as post menopausal breast and colorectal, as well as other chronic diseases like type 2 diabetes.
In their analysis, researchers used data from NHANES (National Health and Nutrition Examination Survey) from 1988 through 2014 to compare weight loss efforts over the past couple of decades. They found that the percent of Americans with overweight trying to lose weight dropped from 56% to 49% in the past 25 years. This drop occurred in nearly all gender and ethnic categories, but perhaps the most concerning decline was for black women. Almost 8 in 10 black women have overweight or obesity, but those trying to lose weight went from 65.5% to almost 55%. White women and men also showed drops in weight loss efforts.
A large new analysis of research confirms that obesity links to many forms of cancer, supporting AICR’s findings on the obesity-cancer link and highlighting clear evidence that obesity is a major cause of cancer.
The study was published today in the BMJ. It was funded in part by World Cancer Research Fund International, of which AICR is a member.
