A new study suggests that moms of boys are more likely to develop postpartum depression, as are moms who suffer from birth complications.

Researchers are constantly looking at postpartum depression and what factors may come into play when predicting who might be at risk for developing it. A newly released study suggests that one 'risk factor' may come in the form of being a mother to a boy. Additionally, though not as surprisingly, the study found that moms who suffered from birth complications were also more likely to develop postpartum depression (PPD).

Dr. Sarah Johns is one of the researchers from the University of Kent who said that participant moms who gave birth to boys were a whopping 71%-79% more likely to suffer from PPD. She believes that the relationship is from inflammatory immune response, which can be more prevalent as male babies can increase inflammation. Dr. Johns says that is just a theory, as no direct relationship is yet clear.

Dr. Johns also said that knowing a baby boy may increase risk for postpartum depression can help clinicians and practitioners better identify women who may gain benefit from additional postpartum support.

Dr. Sarah Meyers was a co-author of the research and said that prenatal detection of women at-risk could make a difference for those women after they give birth. Often women who show obvious signs of depression, anxiety or stress are at a risk for postpartum depression but because they show symptomology, a plan is often in place for supporting them postpartum and they don't end up with PPD as much. Dr. Meyers and Dr. Johns agree that preventative plans can make a big difference.

The study's authors were surprised by the results about boy moms being more at-risk, though not as surprised at the data suggesting mothers who have birth complications/trauma because it makes sense that they may be shocked and confused about what happened during birth. The doctors believe that immediate support of those mothers can make a difference in whether they have postpartum depression, and if they do, maybe it'd be less severe.
