Abstract
This narrative review is based on a literature search on paternal perinatal depression studies published during the last 8 years.
The research has primarily focused on paternal depression prevalence, effects and risk factors. Prevalence rates across the
world have varied although, generally they have increased across pregnancy and the first 6 months postpartum followed by a
decrease at one year postpartum. Paternal depression effects have ranged from continuing depression for the father, marital
discord and negative parenting to sleep disturbances, irritability, hyperactivity and developmental delays in the infants of
depressed fathers. Depression symptoms, attention and behavior problems have been reported for both their genetically related
and adopted children and school performance problems for the adolescents. Risk factors for paternal depression include not
wanting the pregnancy, marital conflict, comorbid maternal prenatal depression, history of depression and unemployment and
stress hormones including higher cortisol levels, lower oxytocin levels and both lower and higher testosterone levels. Very few
intervention and potential underlying mechanism studies have appeared in the literature, although assortative mating,
emotional contagion and hormonal change models have been presented as possible mechanisms. Although the research on
paternal depression has many methodological limitations including variability of measures and confounding variables, paternal
depression is finally being examined alongside maternal depression as serious pregnancy and postpartum conditions.
