Objective : Patients with schizophrenia are at a higher risk for developing insulin resistance and type 2 diabetes mellitus (T2DM). However, few studies have examined abdominal fat and mid-thigh low-density muscle areas, which are known risk factors for insulin resistance and T2DM, in patients with schizophrenia. Therefore, we measured the abdominal fat and mid-thigh low-density muscle areas of schizophrenics and compared them with normal controls.
Methods：Nineteen (four men and 15 women) drug-naive or -free subjects who met the DSM IV criteria for schizophrenia and 19 age- and sex-matched controls were recruited. We measured weight, height, waist circumference, and percent body fat, and calculated the body mass index (BMI). Abdominal fat and mid-thigh low-density
muscle areas were evaluated using computed tomography.
Results：There was no significant difference in terms of age and BMI between the two groups. The areas of abdominal fat (262.4±101.8 vs. 257.1±93.8 ㎠；p=0.919), subcutaneous fat (182.4±72.8 vs. 180.5±75.1 ㎠；p=0.988), visceral fat (79.9±47.2 vs. 76.6±49.3 ㎠； p=0.872), and mid-thigh low-density muscle (15.0±9.9 vs. 15.4±5.2 ㎠, p=0.373) did not differ between schizophrenics and controls.
Conclusion：Abdominal obesity is a well-recognized risk factor for developing certain medical conditions such as insulin resistance and T2DM. We demonstrated that drug-naive or- free patients with schizophrenia do not have increased visceral fat or mid-thigh low-density muscle areas, which might have explained the higher prevalence of insulin resistance and T2DM in these patients.
