Associations Between Postpartum Depressive Symptoms and Couples' Sexual Function and Sexual Distress Trajectories Across the Transition to Parenthood.

Background: The transition to parenthood is associated with changes to new parents' mood and sexual health. Sexual dysfunction-problems with sexual function accompanied by sexual distress (i.e., worries and concerns about one's sex life)-is linked to poorer overall health, yet few studies have examined how sexual dysfunction unfolds for couples during this transition. Postpartum depression is a risk factor for sexual dysfunction; however, the association between depressive symptoms and how postpartum sexual dysfunction evolves has not been examined.

Purpose: To establish trajectories of sexual function and sexual distress for mothers and partners and to examine if postpartum depressive symptoms were associated with these trajectories.

Methods: Data were collected from 203 first-time parent couples from midpregnancy until 12-months postpartum. Sexual function and sexual distress were assessed at six time points (two prenatal) and depressive symptoms were assessed at 3-months postpartum.

Results: Dyadic latent piece-wise growth curve models revealed significant declines in mothers' and partners' sexual function between pregnancy and 3-months postpartum and significant improvements from 3- to 12-months postpartum. Mothers' sexual distress increased between pregnancy and 3-months postpartum and decreased thereafter, whereas partner's sexual distress remained stable. Depressive symptoms were associated with poorer sexual function and higher sexual distress at 3-months postpartum for both partners but did not predict change over time.

Conclusions: Mothers and their partners experience changes to their sexual function during the transition to parenthood; however, mothers are at greater risk of sexual dysfunction. Depressive symptoms are a risk factor for poorer sexual health at 3-months postpartum for both parents.
