population becomes increasingly obese while smoking rates continue to decline, obesity has become an equal, if not greater, contributor to the burden of disease and shortening of healthy life in comparison to smoking. In an article published in the February 2010 issue of the American Journal of Preventive Medicine, researchers from Columbia University and The City College of New York calculate that the Quality-Adjusted Life Years (QALYs) lost due to obesity is now equal to, if not greater than, those lost due to smoking -- both modifiable risk factors. QALYs use preference-based measurements of Health-Related Quality of Life (HRQOL) which allow a person to state a relative preference for a given health outcome. Since one person may value a particular outcome differently than another person, these measures capture how each respondent views his or her own quality of life. Investigators Haomiao Jia, PhD and Erica I. Lubetkin, MD, MPH, state, "Although life expectancy and QALE have increased over time, the increase in the contribution of mortality to QALYs lost from obesity may result in a decline in future life expectancy. Such data are essential in setting targets for reducing modifiable health risks and eliminating health disparities." The article is "Trends in Quality-Adjusted Life-Years Lost Contributed by Smoking and Obesity" by Haomiao Jia, PhD, and Erica I. Lubetkin, MD, MPH. The article appears in the American Journal of Preventive Medicine, Volume 38, Issue 2 (February 2010) published by Elsevier.
