Association between disaster-related factors and formula feeding because of reasons other than concern regarding radioactive contamination
| Disaster-related factors | Univariatea | Multivariateb | ||
|---|---|---|---|---|
| ORc | 95 % CId | OR | 95 % CI | |
| Residential region | ||||
| Within evacuation area (vs Outside evacuation area) | 1.20 | 1.03–1.39 | 1.20 | 1.03–1.41 |
| Continuation of scheduled antenatal care | ||||
| No (vs Yes) | 0.93 | 0.82–1.05 | ||
| Switched to different medical institution of own accord | ||||
| Yes (vs No) | 0.72 | 0.64–0.81 | 0.74 | 0.65–0.84 |
aIndependent variables were 1 = formula feeding because of other reasons and 0 = exclusive breast feeding
bAdjusted for maternal factors (age, parity, and depressive symptoms), obstetric factors (duration between disaster and delivery, type of pregnancy, illness during pregnancy, and delivery method), and child-related factors (gender, body weight, congenital anomalies, and neonatal asphyxia)
c CI confidence interval
d OR odds ratio
