Socio-environmental factors and postnatal depressive symptomatology: a longitudinal study.

This study analyses the relationships between stressful life conditions and postnatal depressive symptomatology in a group of women of low socioeconomic status (SES) and a group of women of high SES from the third to the ninth week postpartum. Nulliparous pregnant women were recruited from the prenatal care clinics of four hospitals. Multiple linear regression analyses demonstrated that after accounting for SES group membership and depressive symptomatology during pregnancy, early postnatal chronic stressors (frequent conflictual episodes with network members, maternal health problems) and social support were linked to later postnatal depressive symptomatology.
