台灣精神分裂症住院病人肥胖盛行率及其特性

The Prevalence and Characteristics of Obesity among Inpatients with Schizophrenia in Taiwan

目的：此文章為台灣第一篇探討精神分裂病住院病人肥胖及腹部肥胖盛行率的研究，並進一步與一般民眾及社區病人做比較。方法：研究對象為西元 20l0年三月期間某療養院慢性病房住院之 710 位精神分裂病病人。根據台灣行政院衛生署：肥胖定義為 body mass index ( BMl ）≥ 27 ，腹部肥胖定義為男性腰圍 > 90cm ，女性腰圍 >80 cm 。結果：研究對象中 60 %為男性，平均年齡 47 . 6 ± 9 . 5 歲，平均發病年齡 32 . 7 ± 10 歲，平均罹患精神分裂症時間 14 . 9 ± 6 . 8 年，平均住院時間 4 . 6 ± 2 . 9 年，肥胖盛行率為 16 . 4 % （男女分別為 14 . 3 %和 19 . 7 % ) ，腹部肥胖盛行率為 53 . 8 %（男女分別為 39 %和 75% ）。結論：精神分裂病住院病人之腹部肥胖盛行率比一般民眾高，而女性住院病人之腹部肥胖盛行率更高達一般民眾的 2 . 2 倍。顯示台灣慢性病房精神分裂病住院病人需要更積極的腹部肥胖介入與預防措施。

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 inpatients with schizophrenia from chronic wards in a mental hospital in Taiwan in March 2010. Obesity and abdominal obesity were defi ned 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 defi nition 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.
