一般注記Objective: The purpose of this study was to elucidate clinical factors influencing quality of life (QOL) in anorexia nervosa (AN) patients. Methods: Twenty female patients with AN (median age = 30.0 years, quartile deviation = 6.8) and forty female healthy controls (HC) (median age = 30.0 years, quartile deviation = 8.6) participated in the study. QOL was assessed with the 36-Item Short Form Health Survey (SF-36) and social support was evaluated using the Multidimensional Scale of Perceived Social Support (MSPSS). Clinical symptoms were evaluated with the Structured Interview Guide for the Hamilton Depression Rating Scale (SIGH-D) and the Eating Disorder Inventory-2 (EDI-2). Results: Scores of the SF-36 Mental Component Summary (MCS) (U = 124.0, P < 0.0001) and Role/Social Component Summary (RCS) (U = 223.0, P = 0.006) and scores of total (U = 108.0, P < 0.0001) and subscales of the MSPSS were lower in AN group than HC group, and the SIGH-D score was higher (U = 46.0, P < 0.0001) in AN group than HC group. Scores of the SIGH-D (ρ = −0.565, P < 0.05) and subscales of the EDI-2 Interoceptive Confusion (ρ = −0.556, P < 0.05), Interpersonal Difficulty (ρ = −0.581, P < 0.05) and Negative Self-image (ρ = −0.617, P < 0.05) were negatively correlated to MCS, and score of Interoceptive Confusion subscale showed a negative correlation to RCS (ρ = −0.672, P < 0.05). Moreover, stepwise regression analysis showed that the SIGH-D score was an independent predictor of MCS and Interoceptive Confusion score predicted RCS. Conclusion: These results suggest that among a variety of clinical symptoms and psychopathologies, depressive symptoms, poor emotional awareness and impaired sense of control are the most important influencing factors on AN patients’ QOL.
