Association Between Maternal Postnatal Depression and Offspring Anxiety and Depression in Adolescence and Young Adulthood: A Meta-Analysis

Objective:Postnatal depression (PND) is common, with an incidence of 10% to 20% in new mothers. Studies have identified an association between maternal PND and adverse childhood effects. Fewer studies have explored the risk of psychiatric disorders in adolescence and adulthood.Methods:MEDLINE, PubMed, PsycINFO, Embase, and EmCare were searched. Studies evaluating the association between maternal PND and offspring anxiety or depression in adolescence or adulthood were included. Five prospective cohort studies met the inclusion criteria. The odds ratios were pooled using a random effects model, and heterogeneity and publication bias were assessed.Results:Anxiety: The 4 relevant studies were composed of 273 mothers with PND and 916 controls, followed up for 12 to 23 years. The pooled odds ratio (OR) was 2.19 (1.33-3.61), p = 0.002, with no heterogeneity (I-2 = 0.00, p = 0.49). Depression: The 5 studies were composed of 937 mothers with PND and 3099 controls, followed up from 12 to 23 years. The pooled OR was 1.92 (1.08-3.42), p = 0.026, with heterogeneity (I-2 = 62.89, p = 0.03).Conclusion:Offspring of mothers with PND are twice as likely to suffer from anxiety and almost twice as likely to suffer from depression than those without exposure. This evidence heightens the importance of detection and treatment of postnatal depression. Furthermore, early assessment and support could be provided to the high-risk group of offspring.
