This cross-sectional study was designed to estimate body mass index (BMI, kg/m^2) of individuals with and without schizophrenia and to examine factors contributing to excessive weight. There were a total of 208 patients (138 men, 70 women) with schizophrenia under hospitalization in a psychiatric hospital and 1,054 controls (797 men, 257 women) without schizophrenia, who underwent overnight medical screening at another university-affiliated hospital in the same area of Japan in 1998. The mean BMI among the 208 patients with schizophrenia was 24.44±4.0 compared with a mean BMI of 23.64±2.7 in healthy controls. There were no significant differences between male patients and male controls ; however, mean BMI was higher in female patients than in female controls, especially among patients under 60 years of age. As weight gain (with increase in BMI) after initiation of medication for schizophrenia is associated more with female gender and younger age, education and support to prevent obesity is particularly important for younger female patients.
