Call to measure duration of obesity
Experts say the health hazards of obesity may have been grossly underestimated because we are not measuring the condition adequately. Risk calculations have focused on severity of weight gain alone and not how long it persists. Latest research suggests every additional decade of being obese more than doubles death risk. The researchers told the International Journal of Epidemiology a new measure is needed - the "obese-year". Similar to the "pack-year" used for smoking, it gives a further quantification that can be used to help estimate the associated health risks.
