**1. Introduction**

Anorexia nervosa (AN) and Bulimia nervosa (BN), are characterized by clinical conditions in body shape and eating attitudes. The core feature of AN is cognitive abd affective disturbance in body image. For example, subjects with AN thought themselves as fat even when they are very thin. They deny the severe thinness to their body weight and have afear of weight gain together with a constant desire for thinness. Thus, they fail to maintain an adequate body weight and shape; girls and women with AN may experience amenorrhea.BN is always concern about their body weight and shape, leading to binging and self-vomiting [1–3]. Claydon et al. [4] concluded that higher risk for relapse of ED was a maternal period and it was a difficult time for EDs with mind and body. In addition, Nakai et al. [5] reported postnatal depression had a close relationship with EDs. One of the recent studies, Watson et al. [6] showed both mothers and their infants complications

were detected during pregnancy and afterbirth.Ex-EDwomen may give birth to premature babies; infants born to these women's' infants may not have an appropriate weight. This study was designed to assess ED relapse rate during pregnancy and after childbirth as well as postnatal depression in women experienced complete remission from EDs. Moreover, we investigated the relationship between ED relapse and postnatal depression, and family support.
