  1. aColumn proportions are shown for the total distribution.
  2. bLogistic regression analysis was used. Multivariate analysis controlled for maternal age (yr; aOR = 0.98, 95% CI = 0.97–0.99), obstetrical complications before the disaster (ref = no; aOR = 1.35, 95% CI = 1.17–1.56), infant’s asphyxia (ref = no; aOR = 1.57, 95% CI = 0.99–2.47), and congenital anomaly (ref = no; aOR = 1.96, 95% CI = 1.46–2.62), along with residential region (ref = Kenchu; Kenpoku aOR = 1.16, 95% CI = 1.01–1.33; Kennan aOR = 0.95, 95% CI = 0.76–1.18; Soso aOR = 1.15, 95% CI = 0.95–1.39; Iwaki aOR = 0.81, 95% CI = 0.68–0.95; Aizu and Minamiaizu aOR = 0.77, 95% CI = 0.64–0.92).
  3. cFifty-two women who gave multiple reasons for referral and 134 women with unknown reason for facility change were excluded.
