Body mass index (BMI) was calculated for 37 674 men over 20 years of their life, between the ages of 25 and 45. Percentile BMI values were then determined for each age and plotted on the graph. For example, along the 75th percentile, 75 % of the population at a given age will have a BMI lower than the BMI indicated by the graph and 25 % of the population will have a higher BMI. The graph also shows the 50th percentile BMI curves for the men in this study who developed diabetes.
