When waist size is considered, body mass index does not relate to the odds of having diabetes.

People with larger waist sizes or higher body mass index have greater odds of having high blood pressure, abnormal cholesterol, and metabolic syndrome even after accounting for the other measure and other factors.

People with larger waist sizes tend to have higher blood pressure, cholesterol, triglycerides, and blood sugar levels even when their body mass index is the same, and the same is true for people with higher body mass index when their waist size is considered.
