Body Mass Index and Diabetes Risk

A new study suggests that diabetes risk may increase with the number of excess years with a high body mass index (BMI).

BMI is a tool for indicating weight status in adults. It is a measure of weight for height. For adults over 20 years old, BMI falls into one of these categories: Below 18.5 (underweight), 18.5-24.9 (normal), 25.0-29.9 (overweight) and 30.0 and above (obese).

Researchers examined data from 8157 adolescents and young adults 14-21 years-old at the start of the National Longitudinal Survey of Youth. Participants reported height, weight and diabetes status from 1981 through 2006. The authors calculated "excess BMI-years" by subtracting the actual BMI from the reference BMI, which is 25.0 for adults or the 85th percentile for adolescents. The excess BMI were combined for each study year.

Authors found that excess BMI-years were associated with an increased risk of diabetes. As an example, authors reported that 40 year-old white men with 200 excess BMI-years were 2.94 more likely to develop diabetes than men of the same age and race with 100 excess BMI-years.

Additional research is warranted in this area.
