Insights
Maternal perinatal depression is linked to poorer child executive function. This systematic review and meta-analysis highlights a small but significant association, underscoring the need for robust research methods.
Area of Science:
- Developmental Psychology
- Neuroscience
- Public Health
Background:
- Maternal depression during the perinatal period is a known risk factor for adverse child developmental outcomes.
- The precise mechanisms linking maternal depression to child outcomes remain unclear.
- Child executive function, crucial for social, emotional, and educational success, is a potential mediating pathway.
Purpose of the Study:
- To systematically review and meta-analyze the evidence on the association between maternal perinatal depression and child executive function.
- To evaluate the quality of existing research in this area.
- To provide a quantitative estimate of the relationship.
Main Methods:
- Comprehensive literature search across major databases (Medline, Embase, PubMed, PsycInfo, SCOPUS) up to August 2020.
- Inclusion of 27 studies measuring maternal depressive symptoms and child executive function.
- Meta-analysis of 16 studies with available raw data.
Main Results:
- Systematic review revealed limitations in the assessment of maternal depression and child executive function, and inconsistent control for confounders.
- Meta-analysis found a small, statistically significant association between maternal perinatal depression and child executive function (effect size r = 0.07, Cohen's d = 0.14).
Conclusions:
- The findings support the hypothesis that maternal perinatal depression impacts offspring executive function.
- Results should be interpreted cautiously due to the variable quality of included studies.
- Future research requires rigorous measurement of depression and executive function, considering chronicity and developmental context.
Background:
Maternal depression during the perinatal period predicts adverse developmental outcomes for children, via poorly understood mechanisms. One plausible pathway may involve child executive function, a suite of cognitive capacities associated with social, emotional and educational outcomes. Systematic review and meta-analysis are applied to evaluate evidence of association between maternal perinatal depression and child executive function.
Methods:
Medline, Embase, PubMed, PsycInfo, and SCOPUS were searched for relevant articles to August 2020, with hand-search of relevant bibliographies. Original research published in English measuring maternal depressive symptoms during pregnancy and the first year postpartum, and child executive function outcomes at any age was included. 27 studies met criteria for review. 16 studies reporting raw data of the association between depressive symptoms and executive function were used for meta-analysis.
Results:
Our systematic review identified inadequate assessment of maternal depression, and unreliable measures of executive function in many studies. Assessment of confounders was also inconsistent. Our meta-analysis identified a small, statistically significant relationship between perinatal depression and child executive function (effect size r = 0.07; 95% CI 0.03-0.10); equivalent to Cohen's d = 0.14.
Limitations:
Variable quality of available studies leads to cautious interpretation of results.
Conclusions:
This meta-analysis is consistent with the hypothesis that maternal perinatal depression does have an impact on executive function in offspring. Future studies must use robust measurement of depression and executive function, and account for the chronicity of maternal depression, and developmental context to produce meaningful results.
