Breastfeeding interventions for preventing postpartum depression

There is low-certainty evidence that psychosocial breastfeeding interventions may prevent postpartum depression in the short term and increase the duration of breastfeeding in the long-term. The evidence is very uncertain about the effect of psychosocial breastfeeding interventions on other outcomes. The evidence is very uncertain about the effect of alternative breastfeeding interventions on postpartum depression or other outcomes. The included studies did not report any adverse events directly related to the interventions, but it is not clear if this outcome was measured in most studies. Future trials of breastfeeding interventions should be conducted carefully to reduce their risk of bias, and they should be large enough to detect differences between mothers in their mental health.
