The positive impact of an intervention for maternal depression on child emotional and behavioral symptoms in a low-resource setting

Objectives: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression by community-based health workers would decrease behavioral/emotional symptoms in their children. Interventions for maternal depressive symptoms in a low/middle-income country can have a high global impact. Methods: Community-based health workers were trained to deliver a psychosocial intervention for mothers with depression in a primary care setting. A total of 49 mothers and 60 children were assessed pre-intervention, post-intervention, and at 6 months follow-up. Child behavioral/emotional symptoms were evaluated according to type of change in maternal depressive symptoms: response or remission. Results: An overall decrease in maternal depressive symptoms from baseline to post-intervention and 6 months follow-up were found. Response or remission was associated with better outcomes in child behavioral/emotional symptoms at 6 months follow-up (p = 0.0247, Cohen's d: 0.76; p = 0.0224, Cohen's f: 0.44) but not at post-intervention (p = 0.1636, Cohen's d: 0.48; p = 0.0720, Cohen's f: 0.33). Conclusions: Improvement in maternal depression was related to decreased behavioral/emotional symptoms in their children. Our results suggest that providing interventions for maternal depression in primary care is a viable strategy to prevent behavioral/emotional symptoms in the next generation.

The positive impact of maternal depression intervention on children's emotional and behavioral symptoms in a low-resource setting.

OBJECTIVE: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression delivered by community health workers (CHW) would decrease behavioral/emotional symptoms in their child. An intervention treating maternal depressive symptoms in a low-middle-income country can have a high global impact. METHODS: CHW were trained to deliver a psychosocial intervention for mothers with depression in a primary care setting. 49 mothers and 60 children were assessed pre-intervention, post-intervention, and at a 6-months follow-up. Child behavioral/emotional symptoms were evaluated by type of change in maternal depressive symptoms: remission and response. RESULTS: An overall decrease in maternal depressive symptoms from baseline to post-intervention and 6-month follow-up were found. Remission and response of maternal depression was associated with better outcomes related to child´s behavioral/emotional symptoms at the 6-month follow-up (p = 0.0247, Cohen's d: 0.76; p = 0.0224, Cohen's f: 0.44) but not at post-intervention (p = 0.1636, Cohen's d: 0.48; p = 0.0720, Cohen's f: 0.33). CONCLUSION: Maternal depression improvement was related to their child's decreased behavioral/emotional symptoms. Our results suggest that interventions addressing maternal depression in primary care is a viable strategy to prevent behavioral/emotional symptoms in the next generation.

The relationship between recent PTSD secondary to sexual assault, hippocampal volume and resting state functional connectivity in adolescent girls.

Objective: Improved understanding of the time course of neural changes associated with adolescent PTSD would elucidate the development of the disorder and could inform approaches to treatment. We compared hippocampal volumes and resting state functional connectivity (RSFC) in adolescent girls with post-traumatic stress disorder (PTSD) secondary to sexual assault, within six months of onset and age- and gender-matched, non-trauma exposed healthy controls (HCs) in São Paulo, Brazil. We also examined the relationship between pre- and post-treatment PTSD symptoms and RSFC. Method: We collected brain structure, RSFC, and PTSD symptoms in 30 adolescents with PTSD (mean age: 15.7 ± 1.04 years) and 21 HCs (mean age: 16.2 ± 1.21 years) at baseline. We collected repeated measures in 21 participants with PTSD following treatment; 9 participants dropped out. Hippocampal volume and RSFC from hippocampal and default mode network (DMN) seeds were compared between participants with PTSD and HCs. We examined associations between within-subject changes in RSFC and PTSD symptoms following treatment. Results: No hippocampal volumetric differences between groups were found. Compared to HCs, adolescents with recent PTSD had reduced RSFC between hippocampus and the lateral parietal node of the DMN, encompassing the angular gyrus, peak coordinates: -38, -54, 16; 116 voxels; peak F 1,47 = 31.76; FDR corrected p = 0.038. Improvements in PTSD symptoms were associated with increased RSFC between hippocampus and part of the lateral parietal node of the DMN, peak coordinates: -38, -84, 38; 316 voxels; peak F 1,47 = 40.28; FDR corrected p < 0.001. Conclusion: Adolescents with recent PTSD had reduced hippocampal-DMN RSFC, while no group differences in hippocampal volume were found, suggesting that hippocampal function, but not structure, is altered early in the course of PSTD. Following treatment, hippocampal-DMN RSFC increased with symptom improvement and may indicate an important neural mechanism related to successful PTSD treatment.

Mental health of children who work on the streets in Brazil after enrollment in a psychosocial program.

PURPOSE: To evaluate the mental health status of children working on the streets in Sao Paulo City, Brazil, two years after their participation in a psychosocial program, and to identify factors associated with their mental health status. METHODS: From a total sample of 126 children working on the streets, 107 (85%) were re-evaluated two years after the initiation of a psychosocial program which aimed to cease their work on the streets. The focus was the presence of mental health problems, defined based on a screening instrument (Strengths and Difficulties Questionnaire). Logistic regression models tested factors related to the probability that a child would not present mental health problems at follow-up. RESULTS: The likelihood of a child presenting mental health problems was higher at baseline compared to the two-year follow-up (67.5 and 56.1%, respectively). Absence of mental health problems two years after a psychosocial intervention was significantly correlated with the following baseline factors: lower level of caregiver's psychiatric symptoms as measured by the SRQ (Self-Report Questionnaire) (AOR = 0.84, p = 0.0065), absence of child physical neglect (AOR = 0.38, p = 0.0705) and parental Protestant religion affiliation, compared to other religions (AOR = 4.06; p = 0.0107). CONCLUSIONS: Different factors are related to the absence of mental health problems of children working on the streets after enrollment in a two-year psychosocial program. Our findings suggest that interventions that aim to improve child mental health should consider the detection of psychiatric symptoms in caregivers, provide treatment when it is needed, and also assess other problems such as neglect in the family setting.
