The primary objective of this review is to assess the effects, on mothers and families, of interventions (other than psychosocial, psychological and pharmacological) compared with usual care in postpartum depression.

Secondary objectives are to examine the effectiveness of:

1. specific types of physical therapies (e.g. bright light therapy, physical exercise, yoga, acupuncture, sleep deprivation);
2. specific types of nutraceuticals (e.g. omega-3 fatty acids);
3. specific types of herbal remedies (e.g. St. John's Wort).
