Obesity Can Cut 19 Years of Health, 8 Years of Life

Article excerpt


Excess body weight could lower "healthy life-years" by as much as 19 years, in addition to reducing life expectancy in certain demographics by as much as 8 years, new research published in Lancet Diabetes & Endocrinology suggests.

"The pattern is clear: The more an individual weighs and the younger their age, the greater the effect of excess weight on health," wrote Dr. Steven A. Grover and his coinvestigators at the Research Institute of the McGill University Health Centre, Montreal.

They created a disease-simulation model, and by using data from 3,992 non-Hispanic white participants in the National Health and Nutrition and Examination Survey (NHANES) during 2003-2010, they estimated the annual risk of diabetes, cardiovascular disease, and mortality. They compared people with an ideal body mass index of 18.5 up to 25 kg/[m.sup.2] against overweight people with BMI of 25 up to 30 kg/[m.sup.2], obese participants with a BMI of 30 up to 35 kg/[m.sup.2], and very obese persons with a BMI of 35 kg/[m.sup.2] and higher. Health life-years lost was defined as years free of cardiovascular disease (CVD) and diabetes.

Depending on their age and sex, overweight individuals were estimated to lose 0-3 years of life expectancy, obese individuals could lose 1-6 years of life expectancy, and very obese individuals were estimated to lose 1-8 years.

Younger adults with high body fat were generally at a greater risk for developing health problems than those who developed obesity later in life (Lancet Diabetes Endocrinol. …
