Abstract

OBJECTIVE

The current study analyzed the variables related to rehospitalization after total weight recovery in adolescents with anorexia nervosa.

METHOD

One hundred and one patients first admitted for inpatient treatment, aged 11-19 years, were followed up for 12 months after discharge.

RESULTS

Twenty-five subjects (24.8%) required readmission after complete weight recovery and 76 (75.2%) did not. Duration of disorder, weight loss, body mass index at first admission, and global body image distortion were similar in the two groups. Patients needing readmission had a lower rate of weight gain (p < .001), a lower mean age (p = . 007), a higher mean score on the Eating Attitudes Test (EAT; p = .009), and a higher percentage of hips overestimation (p = .049). In a stepwise logistic regression analysis, these three variables predicted readmission and correctly classified 77.6% of patients. Taken as discrete variables, age younger than 15 years old, EAT score above 55, and a rate of weight gain lower than 150 grams per day were associated with a higher percentage of readmissions.

DISCUSSION

The variables most clearly related to readmission were young age, abnormal eating attitudes, and a low rate of weight gain.

摘要

目的

本研究分析了神经性厌食症青少年完全恢复体重后再次住院相关的变量。

方法

101例首次因住院治疗入院的患者，年龄在11 - 19岁之间，出院后随访12个月。

结果

25名受试者（24.8%）在完全恢复体重后需要再次入院，76名（75.2%）不需要。两组在疾病持续时间、体重减轻、首次入院时的体重指数以及整体身体意象扭曲方面相似。需要再次入院的患者体重增加率较低（p < .001），平均年龄较低（p = .007），饮食态度测试（EAT）平均得分较高（p = .009），髋部高估的百分比更高（p = .049）。在逐步逻辑回归分析中，这三个变量可预测再次入院情况，且能正确分类77.6%的患者。作为离散变量，年龄小于15岁、EAT得分高于55分以及体重增加率低于每天150克与更高的再次入院百分比相关。
