The Prevalence and Characteristics of Obesity among Inpatients with Schizophrenia in Taiwan
台灣精神分裂症住院病人肥胖盛行率及其特性
摘要
Objectives: This study was intended to investigate the prevalence and characteristics of obesity and abdominal obesity among inpatients with schizophrenia, and to compare with outpatients and persons in the general population. Methods: We recruited 710 patients with schizophrenia from chronic wards in a mental hospital in Taiwan in March 2010. Obesity and abdominal obesity were defined as the body mass index (BMI) ≥ 27 as well as waist circumference ＞ 90 cm in male, and ＞ 80 cm in female patients, respectively, by the definition set by the Department of Health, Executive Yuan, Taiwan 2002. Results: We analyzed demographic characteristics of 710 participants, including 426 male (60%) and 284 female (40%) patients. The mean age was 47.6 ± 9.5 years and the mean age of onset of the disease was 32.7 ± 10 years. The average length of illness was 14.9 ± 6.8 years, while the mean length of hospitalization was 4.6 ± 2.9 years. The overall prevalence of obesity was 16.4%, with 14.3% in male and 19.7% in female patients, respectively. The overall prevalence of abdominal obesity was 53.8%, with 39.7% in male and 75% in female patients. Conclusion: The prevalence of abdominal obesity among schizophrenic inpatients was higher than that among persons in the general population. Female inpatients had 2.2-fold higher prevalence of abdominal obesity than persons in the general population. Therefore, we suggested that active prevention and intervention for abdominal obesity among inpatients with schizophrenia on chronic wards in Taiwan are needed.
