In a recent study evaluating maternal antenatal mood and child development, Milgrom et al. (2019) found that treating depression and anxiety during pregnancy improved neurodevelopmental outcomes in children. In the study, 54 pregnant women were enrolled. All participants were less than 30 weeks pregnant and showed depression and anxiety symptoms during screening. Half of the participants were treated using cognitive behavioral therapy (CBT), and the other half received treatment as usual (TAU) and were considered a comparison group. Information on mothers and their children’s mental health was collected at the beginning of the study, 2 years and 5 years later. Results showed that mothers who were treated for depression and anxiety during pregnancy had children with better psychological, cognitive, behavioral and developmental outcomes. For example, children of treated mothers were found to have better reactivity and self-regulation in response to emotional distress or unexpected change, better motor development, and cognitive performance such as processing speed. Moreover, mothers who completed therapy sessions during pregnancy were found to have lower parental stress 2 years later, compared to mothers who did not. This shows that treating prenatal depression and anxiety is not only beneficial to the child, but also to the mother herself.
In sum, studies have shown that maternal distress can be transmitted from mother to child during pregnancy, negatively impacting child development. Fortunately, another line of research has also shown that treating maternal distress during pregnancy can prevent and/or improve adverse developmental outcomes in children. Therefore, healthcare providers as well as pregnant women are urged to pay close attention to depression, anxiety, and stress during pregnancy, in order to treat symptoms should they be experience. This becomes crucial for both the mother and the child’s physical and psychological health.
