BACKGROUND: The present retrospective study aims to provide additional evidence supporting the fact that waist circumference, in severe obesity, is not a good clinical marker to identify individuals with the metabolic syndrome or an altered metabolic profile. METHODS: Relationships between waist circumference and metabolic profile of pre- (n=165) and postmenopausal (n=43) severely obese women were compared to associations observed in pre- (n=52) and postmenopausal (n=35) moderately obese women. RESULTS: Results showed that abdominal obesity assessed by waist circumference was more highly correlated with fasting glycemia, HDL-cholesterol and the cholesterol/HDL-cholesterol ratio in moderately than in severely obese women, before menopause. After menopause, waist circumference was not a valuable predictor of metabolic abnormalities in both groups. Moreover, when waist circumference was included as a criterion of the metabolic syndrome (as defined by the NCEP ATP III guidelines) in severely obese women, the prevalence of this metabolic condition was over-estimated by 72%. CONCLUSION: These results emphasize the uselessness of waist circumference to assess the prevalence of the metabolic syndrome or an altered metabolic profile in severely obese women.
