Waist-to-Height Ratio Is More Predictive of Years of Life Lost than Body Mass Index

YLL relative to BMI 24 in male non-smokers.
There is a J-shaped association between BMI and YLL at all three of the representative ages. The optimal YLL is at BMI 24 kg/m2 for males and YLL figures relate to this reference BMI value. The ‘accepted normal’ BMI category ranges from 18.5 to less than 25 kg/m2. Surprisingly, males have slight increased YLL in part of the ‘normal’ BMI category (ie BMI from 18.5 to to 22 kg/m2). Males have increased YLL compared with females in the ‘overweight’ category (ie BMI from 25 to 30 kg/m2) at all three of the representative ages.
