In Reply Laurent and Bianchi are concerned that our recent study1 on paternal antenatal and postnatal depression symptoms did not control for prepregnancy depression. Mother and partner participants were recruited to the study during pregnancy.2 As such, it was not possible to carry out standardized assessment of prepregnancy depression symptoms. However, participants were asked to report whether they had ever been diagnosed as having depression by a physician. This variable was included in the models for paternal antenatal depression symptoms (PADS) and paternal postnatal depression symptoms (PPDS). Prepregnancy depression was significantly associated with PPDS (increased odd ratio, of 2.84; 95% CI, 1.69-4.78) and all other odds ratios were controlled for this variable.
