Antenatal depression predicts depression in adolescent offspring: prospective longitudinal community-based study

Area of Science:

• Psychiatry
• Developmental Psychology
• Public Health

Background:

• Maternal depression, particularly untreated postnatal depression, is linked to adverse child outcomes.
• Few studies have prospectively examined the long-term impact of maternal depression from pregnancy through adolescence on offspring mental health.

Purpose of the Study:

• To investigate the prospective course of maternal depression from pregnancy to 16 years postpartum.
• To assess the relationship between maternal depression and adolescent offspring depression.

Main Methods:

• Longitudinal study of 127 mother-child dyads followed from pregnancy to 16 years.
• Maternal depression course and offspring depressive disorders at age 16 were assessed.

Main Results:

• Two-thirds of mothers experienced depression during the 17-year period, with most having recurrent episodes.
• 14% of adolescent offspring were diagnosed with depression; all had been exposed to maternal depression.
• Antenatal depression exposure increased offspring depression risk 4.7-fold, mediated by repeated maternal episodes.

Conclusions:

• Detecting depression during pregnancy identifies mothers at risk for recurrent episodes and children at risk for adolescent depression.
• Early identification and intervention for antenatal depression are crucial for mitigating long-term offspring mental health risks.
