CORE-OM=clinical outcomes in routine evaluation-outcome measure; SF-12 MCS=short form 12 mental component summary; SF-12 PCS=short form 12 physical component summary; PSI-SF=parenting stress index short form. Better health represented by lower score in EPDS, CORE-OM, and STATE anxiety; higher score in others

*Adjusted for six week score, living alone, history of postnatal depression, any life events.
