Impact of maternal depressive symptoms on offspring executive functions: a systematic review.

OBJECTIVE: This systematic review aims to thoroughly examine the current understanding of the effect of maternal depression exposure on the executive functions of offspring. METHODS: Following the PRISMA statement, a comprehensive search for peer-reviewed cohort studies was performed on Pubmed, ScienceDirect, LILACS, PsychINFO, and SciELO. Study quality was assessed using the NIH National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort and Cross-sectional studies. The evidence was evaluated using the Grading of Recommendation, Assessment, Development, and Evaluation. RESULTS: This review analyzed 33 cohort studies from different countries with a total of 38,981 participants. Twenty-four studies confirmed the hypothesis of the harmful effect of maternal depressive symptoms on the performance of children's executive functions. However, a high heterogeneity among studies was found, and meta-analysis was not feasible. Fetal programming, genetics, and parental practices have been identified as potential mechanisms that can affect the executive functions of children born to mothers who have experienced depressive symptoms. CONCLUSIONS: The results suggest a negative association between maternal depressive symptoms and offspring executive functioning. Further studies on the effects of chronicity/severity of maternal symptoms and changes in executive functions in different sensitive periods are needed.

Maternal depression and offspring mental health at age 5: MINA-Brazil cohort study.

OBJECTIVE: To identify longitudinal patterns of maternal depression between three months and five years after child's birth, to examine predictor variables for these trajectories, and to evaluate whether distinct depression trajectories predict offspring mental health problems at age 5 years. METHODS: We used data from the Maternal and Child Health and Nutrition in Acre (MINA-Brazil) study, a population-based birth cohort in the Western Brazilian Amazon. Maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) at 3 and 6-8 months, and 1 and 2 years after delivery. Mental health problems in 5-year-old children were evaluated with the Strengths and Difficulties Questionnaire (SDQ) reported by parents. Trajectories of maternal depression were calculated using a group-based modelling approach. RESULTS: We identified four trajectories of maternal depressive symptoms: "low" (67.1%), "increasing" (11.5%), "decreasing" (17.4%), and "high-chronic" (4.0%). Women in the "high/chronic" trajectory were the poorest, least educated, and oldest compared with women in the other trajectory groups. Also, they were more frequently multiparous and reported smoking and having attended fewer prenatal consultations during pregnancy. In the adjusted analyses, the odds ratio of any SDQ disorder was 3.23 (95%CI: 2.00-5.22) and 2.87 (95%CI: 1.09-7.57) times higher among children of mothers belonging to the "increasing" and "high-chronic" trajectory groups, respectively, compared with those of mothers in the "low" depressive symptoms group. These differences were not explained by maternal and child characteristics included in multivariate analyses. CONCLUSIONS: We identified poorer mental health outcomes for children of mothers assigned to the "chronic/severe" and "increasing" depressive symptoms trajectories. Prevention and treatment initiatives to avoid the adverse short, medium, and long-term effects of maternal depression on offspring development should focus on women belonging to these groups.

Risk factors for executive function impairment in adolescence: an analysis of data from the 2004 Pelotas Birth Cohort study

Objective: To investigate risk factors associated with impaired attention-related executive functions (EFs) at age 11 and working memory at age 15. Methods: Data from participants of the population-based 2004 Pelotas Birth Cohort at ages 11 (n=3,582) and 15 (n=1,950) were analyzed. The study measured attentional control, cognitive flexibility, and selective attention using the Test of Everyday Attention for Children (TEA-Ch). Spatial working memory was assessed by the Cambridge Neuropsychological Test Automated Battery (CANTAB). Logistic regression was employed to explore the relationship between perinatal and childhood exposures and EF impairment. Results: Low maternal education had a significant negative impact on EFs. At age 11, it was associated with decreased attentional control (OR = 3.04; 95%CI 2.09-4.43), and at age 15, it was linked to impaired spatial working memory (OR = 2.21; 95%CI 1.58-3.09). Additional risk factors included low household income, black or brown maternal skin color, high parity, prematurity, low birth weight, and multiple siblings. Breastfeeding, regardless of duration, was found to be a protective factor against impaired cognitive flexibility (OR = 0.38; 95%CI 0.22-0.65). Conclusion: This study underscores the lasting impact of perinatal exposures on EF development. Policies that mitigate the negative effects of risk factors and promote EF development, especially among vulnerable populations, are needed.

RESUMO OBJETIVO: Identificar padrões longitudinais de depressão materna entre três meses e cinco anos após o nascimento de seus filhos, analisar variáveis preditoras dessas trajetórias e avaliar se trajetórias distintas de depressão predizem problemas de saúde mental infantil aos cinco anos de idade. MÉTODOS: Utilizou-se dados do estudo sobre saúde e nutrição materno infantil no Acre (MINA-Brasil), uma coorte de nascimentos de base populacional na Amazônia ocidental brasileira. Os sintomas depressivos maternos foram avaliados pela Escala de Depressão Pós-parto de Edimburgo (EPDS) aos 3 e 6-8 meses e 1 e 2 anos após o parto. Problemas de saúde mental em crianças com cinco anos de idade foram avaliados pelo Questionário de Capacidades e Dificuldades (SDQ- Strengths and Difficulties Questionnaire), respondido pelos pais. As trajetórias de depressão materna foram calculadas usando uma abordagem de modelagem baseada em grupos. RESULTADOS: Foram identificadas quatro trajetórias de sintomas depressivos maternos: "baixa" (67,1%), "crescente" (11,5%), "decrescente" (17,4%) e "alta-crônica" (4,0%). As mulheres na trajetória "alta/crônica" eram mais pobres, menos escolarizadas, mais velhas e multíparas e relataram tabagismo com maior frequência e menor número de consultas de pré-natal durante a gestação do que as demais. Nas análises ajustadas, a razão de chances de qualquer transtorno do SDQ foi 3,23 (IC95%:2,00-5,22) e 2,87 (IC95%: 1,09-7,57) vezes maior entre os filhos de mães nos grupos de trajetória "crescente" e "alta-crônica", respectivamente, do que de mães do grupo de sintomas depressivos "baixos". As características maternas e infantis incluídas nas análises multivariadas foram incapazes de explicar essas diferenças. CONCLUSÕES: Identificou-se piores desfechos de saúde mental para filhos de mães atribuídas às trajetórias "crônica/grave" e "crescente" de sintomas depressivos. Iniciativas de prevenção e tratamento para evitar os efeitos adversos a curto, médio e longo prazo da depressão materna sobre o desenvolvimento de seus filhos devem se concentrar principalmente nas mulheres nesses grupos.
