Background: Having a first child is a key marker of the transition into parenthood that requires substantial adjustment of couples' life. A recent meta-analysis published in the Journal of American Medical Association reports that both women (23.8%) and men (10.4%) suffer from perinatal depression [1]. The father's involvement during pregnancy can positively influence health outcomes not only for the man, but his partner, and their children [1,2]. However, the effectiveness of father's involvement in prenatal care in preventing paternal and maternal depression, is still unknown.
