Abstract

This study tested 60 men, aged <40 years, with a BMI 27-35 kg/m(2) to determine whether they had metabolic syndrome. The three definitions used to test this were from the National Cholesterol Education Program (NCEP), the World Health Organization (WHO) and the International Diabetes Federation (IDF). Further, the relationship between a positive definition and plasma testosterone (T) and calculated free T was analysed. Using the above three definitions of metabolic syndrome (MetS), there was a large degree of overlap of identifying obese men as having the syndrome, but there were quantitatively significant differences as well. So, it is relevant in studies to identify which of the present definitions of the syndrome has been used. With aging there is an increasing prevalence of the syndrome and age itself might be a factor in the lower T levels encountered in these men. But low plasma total T and calculated free T were also consistent features of men <40 years with metabolic syndrome, regardless of which definition had been applied. Including low T levels in the definition of metabolic syndrome, may be helpful.
