Effect of intravenous iron versus oral iron on rate of cessation of breast feeding
| HR* | 95% CI | p Value | |
|---|---|---|---|
| Intravenous plus oral | 0.70 | (0.50 to 0.99) | 0.046 |
| Maternal age | 0.76 | (0.63 to 0.92) | 0.006 |
| Downheartedness | 1.23 | (1.00 to 1.52) | 0.055 |
| Current alcohol intake | 1.34 | (0.88 to 2.03) | 0.18 |
| Mode of delivery: | |||
| NVD | 1.00 | ||
| LSCS | 1.24 | (0.84 to 1.82) | 0.29 |
| Forceps | 1.39 | (0.85 to 2.27) | 0.19 |
*The likelihood of cessation of breast feeding in the intravenous plus oral iron group was compared with that of the oral iron only group: estimated using Cox proportional hazards regression corrected for repeated-measures and adjusted for the covariates shown, expressed as hazards ratios (95% CIs; p values). Covariates included in the final multivariate model were selected by stepwise regression. The standardised normal transformation of maternal age was used ((mother's age−group mean age)/group SD of age): mean age 28.1±5.6 years. HR less than 1.00 indicates a slower rate of cessation of breastfeeding, while an HR greater than 1.00 indicates a faster rate of ceasing breastfeeding.
NVD, normal vaginal delivery; LSCS, lower segment caesarean section.
