Men with a “spare tire” on their hip are more likely to die from prostate cancer – according to a large study, the risk increases by up to 7 percent for every 10 cm.
Thousands of prostate cancer deaths could potentially be prevented each year if the average man lost weight, researchers claimed.
While obesity has been linked to 13 other cancers – including stomach, liver, pancreas and kidney cancer – the link between prostate cancer and weight has only just been unraveled by scientists.
Academics conducted new research and reviewed previous data on the topic as part of the new study, which will be presented at the European Congress on Obesity in the Netherlands and published in the journal BMC medicine.
In the new study, the researchers looked at data from 218,237 men who participated in the UK Biobank study, whose body mass index (BMI) score, waist circumference and waist-to-hip ratio were recorded when they first enrolled in the study.
Participants were followed for an average of 12 years, with 661 men dying of prostate cancer during the follow-up period.
After analyzing the health records of the men who had died from prostate cancer and comparing them to those who had not, the researchers found that for every five additional points on a man’s BMI score, the likelihood of an Dying from prostate cancer was 7 percent higher.
And they had a 6 percent higher risk of dying from prostate cancer for every 4 inches more waist size.
Meanwhile, the researchers also conducted an analysis of previous studies that examined information on nearly 20,000 men who died from prostate cancer.
These studies suggested that for every five additional points on a man’s BMI score, he was 10 percent more likely to die from prostate cancer, and an extra 10 cm of waist size carried a 7 percent greater risk.
While the mechanisms behind the findings are still unknown, the researchers said the study still suggests men should try to maintain a healthy weight.
“Knowing more about the factors that increase the risk of prostate cancer is key to prevention,” said Dr. Aurora Perez-Cornago from Oxford University, who led the research.
“Age, family history, and Black ethnicity are known risk factors, but they are not modifiable, and so it is important to discover risk factors that can be modified.”
Each year more than 3,500 men are diagnosed with prostate cancer in Ireland. However, the survival rate has improved in recent years.
