Low levels of “cuddle hormone” may indicate post-partum depression risk

An article in the May 2011 issue of Neuropsychopharmacology states that there is a possible connection between low oxytocin levels and the risk of postpartum depression. Oxytocin, also known as the “cuddle hormone,” causes labor contractions. Previous research has shown that mothers with higher levels of oxytocin are more likely to smile at their babies.

In this Swiss study, researchers measured oxytocin levels in 73 healthy, pregnant women during the third trimester. The women were screened for their risk of developing depression during pregnancy and within two weeks of giving birth. Based on the screening tests, 14 women were determined to be at risk for postpartum depression. These women had lower levels of oxytocin.
