Antenatal depressive symptoms and behavioral outcomes in children at 78 months: A study from South India.

Background: Low and middle income countries report a higher prevalence of antenatal depression. The association between antenatal depressive symptoms and behavioral outcomes in children at 78 months in motherchild dyads who participated in a randomized control trial of maternal B12 supplementation during pregnancy was examined in this study.

Methods: Children of 140 women, out of 366 who had participated in the placebo-controlled, randomized trial of vitamin B12 supplementation during pregnancy and 6 weeks post-partum, on whom serial assessments of depressive symptoms in each of the trimesters were done using the Kessler's 10 Psychological Distress Scale (K10), were assessed using the Strength and Difficulties Questionnaire (SDQ) at 78 months.

Results: Thirty seven women (26.4%) reported depressive symptoms at one trimester (intermittent group) and 28 women (20%) had depressive symptoms in at least 2 trimesters (persistent group). On adjusted bivariate regression analysis, children of women with intermittent antenatal depressive symptoms scored lower on the prosocial behavior subscale of SDQ compared to children of mothers with no depressive symptoms ( B=;-0.91, 95% CI: -1.65,-0.18; p=0.016).

Limitations: The use of a screening measure to assess maternal depression, the assessment of the children's behavior based only on the mothers' reports and the small number of women with persistent depressive symptoms in our sample is important limitations.

Conclusions: The possible association between antenatal depressive symptoms and prosocial behavior in children point to the need for routine assessment and intervention for emotional disorders during pregnancy.
