Abdominal obesity in men is typically defined using waist circumference measurements, as these can serve as an important indicator of excess visceral fat, which is linked to a higher risk of various health issues. For men, a waist circumference greater than or equal to 40 inches is generally considered indicative of abdominal obesity. This threshold is based on research showing that abdominal fat distribution significantly increases metabolic risks such as type 2 diabetes, cardiovascular disease, and other health conditions.

The other options reflect measurements that do not align with the established criteria for assessing abdominal obesity in men. Measurements below the 40-inch threshold, such as those provided in the other choices, do not signify the same level of health risk associated with higher waist circumferences. Therefore, the correct answer emphasizes the importance of monitoring waist circumference as a key metric in evaluating overall health, particularly with regard to obesity-related risks.
