Variability of waist circumference and its relationship with cardiovascular risk factors in outpatients with schizophrenia.

The magnitude of waist circumference (WC) in schizophrenia patients was measured at three sites (above superior iliac crest, midpoint between lowest rib and iliac crest, and umbilical level), and correlated with lipid profiles, glucose, blood pressure and metabolic syndrome. The mean midpoint WC was significantly smaller than at the other sites.
