A new study on the prevalence of these diseases for the period from 2000 to 2016, revealed a shift in the age of cancer associated with obesity. Typically, these types of cancer are diagnosed in people over 65 years. The most significant results concern the increase in cases among African Americans and Hispanics, who have certain types of cancer increased by 200-400%.
A study published in JAMA Network Open, held command Cancer Case Western Reserve University Center. It is based on the base "Epidemiology, and End Results surveillance" of the data, the authoritative source of cancer statistics in the United States.
"We were surprised by the age difference of cases of cancer are associated with obesity: from the age group of 50-64 years to those aged 20-49 years," - the researchers say. - At the same time the number of people aged 50 to 64 years during this period increased by almost 52%, so the absolute number of people affected by these changes, is sufficiently large. It is also noteworthy that the percentage increase in cases of cancer associated with obesity, is significant, especially among African Americans and Hispanics. "
The researchers point out that many people aged 50 to 64 years with cancer, diagnosed between 2000 and 2016, now survive, and many of them are people with Medicare insurance program. Cancer associated with obesity affects both public health and on public finances.
"We know that public health efforts to address obesity are important effects on health and quality of life health officials is expedient to continue and even step up efforts to inform people about the adverse effects of obesity,." - the researchers say. Obesity-related cancers included in the study, include colon cancer, ovarian cancer, esophagus, stomach and other organs.
The researchers broke the cases of the disease in certain types of cancer based on age, gender and race. Certain types of cancer were significantly higher in some populations, and the contrast between the two groups was striking. In particular, the number of cases dealt with in people aged 50 to 64 years increased by 25% in non-Hispanic women, and nearly 200% for Hispanic women. Among men, the number of cases increased by almost 10%, and among Hispanics - at 100%.
To determine the stage of cancer, which was diagnosed in different populations, more research is needed. Cancer, diagnosed in young adults, is usually detected at later stages, which contributes to a worse prognosis, and premature mortality.
