OBJECTIVE
This study estimated the degree of seasonal changes in eating disorder subtypes in Japan.
METHOD
A Japanese version of the Seasonal Pattern Assessment Questionnaire (SPAQ) was mailed to 228 outpatients with eating disorders in Kyoto (latitude 35 degrees 01' N). Ninety responses were analyzed. The mean of the global seasonality score (GSS) in the SPAQ and the comorbidity rate of seasonal affective disorder (SAD) and subsyndromal-SAD in each subtype were used as indices of seasonality.
RESULTS
The mean (8.2) of the GSS of the bulimia nervosa (BN) group and the sum (43%) of the comorbidity rates of SAD and subsyndromal-SAD in the BN group were significantly higher than those in the nonclinical comparison group.
DISCUSSION
The seasonality of BN in Kyoto is the highest among eating disorder subtypes, although lower than that in North America. This finding suggests that light therapy could be useful for Japanese BN patients.
目的
本研究评估了日本饮食失调亚型的季节性变化程度。
方法
将日语版的季节性模式评估问卷（SPAQ）邮寄给京都（北纬35度01分）的228名饮食失调门诊患者。对90份回复进行了分析。SPAQ中的全球季节性得分（GSS）均值以及各亚型中季节性情感障碍（SAD）和亚综合征性SAD的共病率用作季节性指标。
结果
神经性贪食症（BN）组的GSS均值（8.2）以及BN组中SAD和亚综合征性SAD的共病率总和（43%）显著高于非临床对照组。
讨论
京都BN的季节性在饮食失调亚型中最高，尽管低于北美。这一发现表明光疗法可能对日本BN患者有用。
