Results

A total of 331(21.0%) responses were analyzed; among these 304(91.8%) women had postpartum hair loss.The average time for the start, peak, and end of hair loss was 2.9, 5.1, and 8.1 months, respectively.Logistical regression analyses revealed that longer-term breastfeeding and preterm labor were independent predictors of postpartum hair loss.

Outcome measures

In the questionnaire, the following questions were asked to assess the baseline characteristics: age at delivery, pregnancy and delivery history, height, prepregnancy weight, existing diseases, fertility treatments, current menstrual status, days from delivery to the resumption of menstruation, and smoking and alcohol intake before pregnancy and after delivery. Regarding pregnancy, delivery, and child care, we asked the following questions: delivery week, delivery method (vaginal delivery/elective cesarean section/emergency cesarean section), blood transfusion during labor, infant weight, abnormalities during labor, presence or absence of preterm labor, gestational diabetes mellitus, and hypertensive disorders of pregnancy, infant feeding at 3 months after delivery (breastfeeding/mixed feeding/formula feeding), and the duration of breastfeeding.

For postpartum hair loss, we first inquired about the extent of hair loss using a 4-point Likert scale (not at all, a little, quite a lot, very much). Furthermore, except for those who had no hair loss, the following questions were asked: start, peak, and end time of hair loss; whether they felt anxious or stressed about their hair loss (not at all, a little, quite a lot, very much); when they noticed their hair loss; whether they took any remedial action for their hair loss; and whether they talked to someone about their worries.

Sleep disorder was evaluated using the Athens insomnia scale (AIS), which was developed as a brief and easy-to-administer questionnaire for determining the severity of insomnia defined according to the International Classification of Disease Tenth Revision. Depressive symptoms were assessed using the Edinburgh postnatal depression scale (EPDS). The EPDS, originally developed in the United Kingdom in 1987, is a 10-item self-report measure designed to screen women for symptoms of emotional distress during the postpartum period using a 4-point Likert scale. EPDS was translated into Japanese in 1996, and its reliability and validity have been confirmed.
