What waist circumference indicates increased risk for T2DM and CVD for men?

A waist circumference of 40 inches for men is recognized as a significant indicator of increased risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). This measurement is commonly used in clinical settings, as it reflects excess abdominal fat, which is a risk factor for metabolic syndrome and these chronic conditions.

Abdominal obesity, often assessed through waist circumference, is associated with insulin resistance and adverse changes in lipid profiles, both of which contribute to an increased likelihood of developing T2DM and heart-related issues. In contrast, lower waist measurements, such as 30, 32, or even 35 inches, are considered to be less indicative of such heightened risks. Thus, the waist circumference threshold at 40 inches specifically triggers concern in the public health context, supporting the choice as the correct answer.
