Insights
Maternal depression during pregnancy is linked to lower infant motor skills at six months and language development at twelve months. Early intervention for maternal well-being is crucial for infant neurodevelopment.
Area of Science:
- Neuroscience
- Developmental Psychology
- Perinatal Mental Health
Background:
- Antenatal depression is linked to adverse child outcomes, but its impact on infant neurodevelopment in the first year is understudied.
- Existing research has not sufficiently explored the effects of maternal depression during pregnancy on infant development.
Purpose of the Study:
- To investigate the impact of maternal Major Depressive Disorder (MDD) during pregnancy on infant cognitive, language, and motor development.
- To assess these developmental outcomes at six and twelve months postpartum using a prospective longitudinal design.
Main Methods:
- A prospective longitudinal study included pregnant women with MDD (n=23), a history of MDD (n=34), and a control group (n=43).
- Maternal depression was assessed during pregnancy, and infant development (cognitive, language, motor) was measured at six and twelve months postpartum.
Main Results:
- At six months, infants of mothers with MDD showed significantly lower motor development scores compared to controls, even after controlling for concurrent maternal depression.
- At twelve months, infants in the MDD group exhibited lower language development scores, although this finding attenuated after controlling for maternal depression.
Conclusions:
- Maternal depression during pregnancy is associated with impaired infant motor and language development in the first year.
- These findings underscore the importance of early interventions for maternal mental health to support infant neurodevelopment.
Background:
Antenatal depression is associated with adverse social-emotional and behavioural outcomes during childhood but there has been little investigation of the impact on infant neurodevelopment during the first postnatal year.
Aims:
The aim of this study was to assess the impact of depression during pregnancy on infant cognitive, language and motor development at six and twelve months using a prospective longitudinal study design.
Participants:
Pregnant women with a clinical diagnosis of Major Depressive Disorder (MDD; n = 23), a history of MDD (n = 34) and a control group (n = 43) and their infants.
Outcome Measures:
MDD was measured during pregnancy and both maternal depression and infant cognitive, language and motor development were measured at six and twelve months postpartum.
Results:
At six months, infants in the MDD group had lower motor development scores (M = 95.48, SD = 11.87) compared with controls (M = 99.97, SD = 10.64, p = .026) after controlling for maternal concurrent depression scores. At twelve months, infants in the MDD group had lower language scores (M = 87.33, SD = 10.54) compared with controls (M = 95.06, SD = 11.78, p = .037) which attenuated after controlling for maternal concurrent depression.
Conclusions:
These data contribute to the growing literature investigating the impact of antenatal depression on infant cognitive, language and motor development within the first postnatal year. The association between maternal depression and lower infant motor scores highlights the importance of early intervention for both mothers and infants in situations where maternal well-being is at risk.
