There is a lack of understanding about the impact of different waist circumference (WC) measurements on the detection of abdominal obesity and metabolic syndrome in psychiatric patients. This cross-sectional study included a total of 382 inpatients with schizophrenia-related disorders to assess each component of metabolic syndrome. WC was measured at the lowest rib, midpoint between the iliac crest and lowest rib, iliac crest, minimal waist, and umbilicus. Logistic regression analysis was performed to examine the ability of WC at each site to predict the presence of metabolic risk clustering. The mean WC values for all sites were significantly different from each other. The measurement site had an influence on the prevalence of abdominal obesity (30-38.2% in men and 53.9-86.3% in women). The influence on the prevalence of metabolic syndrome was greater with the International Diabetes Federation (IDF) criteria (19.3-23.9% in men and 29.4-43.1% in women) than with the Adult Treatment Panel III (ATP III) criteria (26.1-28.6% in men and 37.3-44.1% in women). The areas under the receiver operating characteristic curve for metabolic risk clustering were highest at the umbilicus and midpoint. Given that the WC measurement protocol has substantial influence on the prevalence of abdominal obesity and metabolic syndrome, a predefined measurement site is required for all psychiatric studies.
人们对不同腰围（WC）测量值对精神科患者腹部肥胖和代谢综合征检测的影响缺乏了解。本横断面研究共纳入 382 例精神分裂症相关障碍住院患者，评估代谢综合征的各个组成部分。在最低肋骨、髂嵴和最低肋骨中点、髂嵴、最小腰围和脐部测量 WC。使用逻辑回归分析检查每个部位 WC 预测代谢风险聚集存在的能力。所有部位的 WC 平均值之间存在显著差异。测量部位对腹型肥胖的患病率有影响（男性为 30-38.2%，女性为 53.9-86.3%）。国际糖尿病联合会（IDF）标准对代谢综合征患病率的影响大于成人治疗组 III（ATP III）标准（男性为 19.3-23.9%，女性为 29.4-43.1%）。代谢风险聚类的受试者工作特征曲线下面积在脐部和中点最高。鉴于 WC 测量方案对腹型肥胖和代谢综合征的患病率有很大影响，所有精神科研究都需要一个预设的测量部位。
