Two in three adult U.S. citizens fall under the overweight or obese category, report a recent study from the Washington University School of Medicine.
In the survey conducted between 2007 and 2012 on a sample population of 15,208 American citizens aged 25 and above, 75% male and 67% female are either overweight or obese.
Body mass index (BMI) was used as the index to measure overweight and obesity. Two thirds of women presented BMI above the average while only three quarters of the male population presented BMI above the average.
With regard to ethnic and racial factors, 39% male African Americans and 57% female African Americans are obese. Mexican Americans also showed that 38 percent of men and 43 percent of the female population are obese.
"Obesity is going to surpass cigarette smoking as the leading cause of the cancer deaths in the US," Mitchell Roslin, chief of bariatric surgery at Lenox Hill hospital.
Nonetheless, the increase in the number of Americans struggling with their weight is of serious concern to doctors. America's weight has been trending upward for a number of years.
"This is a wake-up call to implement policies and practices designed to combat overweight and obesity," Li Yang, one of the co-authors of the study, said in a statement.
