**2. Methods**

This study was conducted at the Makino Clinic. The ethical committee of the Makino Clinic approved this research (Approved 002). The study purpose and outline were explained to patients, and written informed consent acquired. We treated 1008 EDs at our outpatient clinic between 1994 and 2004. Of these patients, 55 patients experienced ED recovery, pregnancy, and childbirth. Of which, 21 BN and 4 AN agreed to partake in this study; However, we examined 24,because unfortunately, 1 patient experienced a miscarriage. These participants had long-term treatment for EDs. However, they acquired complete remission. We determined remission as 6-months symptoms -free condition. There were some reports for definition of recoveries. Symptoms-free status in the previous 90 d.by Levallious et al. [7] Bardone-Cone et al. [8] reported it as the absence of symptoms in the previous 3 mon, while Zerwas et al. [9] indicating the recovery by 1 y without no symptoms. We chosed a midpoint of these reports. The Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association 2013) [2] does not precisely outline the criteria to consider ED in remission. In Japan, there were no particular determined symptoms used to define remission or recovery. Thus, we made to meet the contents for the including and excluding criteria of the patients and for diagnosing ED remission according to the literature [10, 11]. Then, we examined participants experienced the remission for 6 mon. The Japanese version of the Eating Attitudes Test-26 (EAT-26) made by Ujiie and Kono [12] was adopted for diagnosing of EDs. The Japanese version of the Edinburgh Depression Scale (JEPDS), a self-filled questionnaire, developed by Okano [13] was used as a reference to diagnose postnatal depression as well as the interview.
