Maternal hsa-miR-423-5p associated with the cognitive development of babies in pregnant women without mental disorders.

Background: MicroRNAs (miRNAs) are small non-coding RNAs capable of regulating gene expression post-transcriptionally. MiRNAs are recognized as key regulators of diverse biological and developmental processes. During the pregnancy-puerperal cycle, numerous changes occur in the female body for the formation, growth, and development of the baby. After birth, there is a critical period in child development, as rapid gains in the physical, cognitive, and socio-emotional domains constitute the "building blocks" of children's later growth. Objective: The aim of this study was to investigate the association between maternal expression of hsa-miR-423-5p during the first and second trimesters of pregnancy and neurocognitive development at 90 days of life in infants. Methods: This is a longitudinal study included in a population-based cohort study, carried out in a city in southern Brazil. The Bayley III was used to assess the babies' cognitive development. Blood samples from mothers were obtained for RNA extraction from serum and analysis of miRNA expression by qRT-PCR. Results: In total, 87 dyads (mother-baby) were included. The average gestational age was 15.86 weeks (SD ± 5.55). An association of maternal miRNA with infant cognitive development was found; as maternal miR-423-5p increases, infants' cognitive development increases by 2.40 (95% CI 0.37; 4.43, p = 0.021) points at 3 months of age. Conclusion: In this context, it is suggested to use this miRNA as a biomarker of child neurocognitive development detectable in the prenatal period, thus allowing the planning of early interventions.

Screen time: Implications for early childhood cognitive development.

BACKGROUND: Exposure and introduction to digital media, especially in children, are a current cause for concern. The negative links associated with early screen exposure are extensive. AIMS: To evaluate the association between the time of exposure to a screen in children at 18 months of age and cognitive development in a population-based sample in Southern Brazil. STUDY DESIGN: This was a cross-sectional study corresponding to the fourth wave of a population-based cohort study with pregnant women and later, their children living in the city of Pelotas, Southern Brazil. SUBJECTS: The sample consisted of 470 children who completed the cognitive assessment. OUTCOME MEASURES: Cognitive development was assessed using the Bayley Scales of Infant Development - Third Edition (BSID-III). Exposure to screen time was assessed using a questionnaire completed by the primary caregiver. RESULTS: Of the total, 58.8 % of the children had ≥1 h of screen time per day and the average on the cognitive scale of the entire sample was 96.1 (SD = 14.0). Cognitive development was lower in children whose mothers had lower levels of education (CI 95 % -4.9; -2.1), where boys (CI 95 % 3.2; 8.4) and in children exposed to 2 h or more of screen time/day (CI 95 % -3.6; -0.5). CONCLUSIONS: Exposure to screens may have a significant negative association with children's cognitive development and, therefore, we seek to intervene and to give advice to parents and guardians about the true impact of digital media. Further studies are necessary to consolidate the findings and to disclose information on the topic.

Can glutathione be a biomarker for suicide risk in women 18 months postpartum?

Background: Suicide risk is prominent among the problems affecting populations, mainly due to the broad family, psychosocial and economic impact. Most individuals at suicidal risk have some mental disorder. There is considerable evidence that psychiatric disorders are accompanied by the activation of neuro-immune and neuro-oxidative pathways. The aim of the study is to evaluate the serum levels of oxidative stress biomarkers in women at risk of suicide after 18 months of postpartum. Methods: This is a case-control study, nested within a cohort study. From this cohort, 45 women [15 without mood disorders and 30 with mood disorders (Major depression and Bipolar disorder)] were selected at 18 months postpartum, the depression and suicide risk were assessed using the Mini-International Neuropsychiatric Interview Plus (MINI-Plus) instrument, module A and C, respectively. Blood was collected and stored for later analysis of the reactive species (DCFH), superoxide dismutase (SOD), and glutathione reduced (GSH). For data analysis, the SPSS program was used. To compare the nominal covariates with the outcome GSH levels, the Student's t-test or analysis of variance (ANOVA) was used. Spearman's correlation was performed for analysis between the quantitative covariates and the outcome. To analyze the interaction between the factors, multiple linear regression was performed. Bonferroni analysis was used as an additional/secondary result to visualize differences in glutathione levels according to risk severity. After the adjusted analysis, p-values < 0.05 were considered statistically significant. Results: The percentage of suicide risk observed in our sample of women at 18 months postpartum was 24.4% (n = 11). After adjusting for the independent variables, only the presence of suicide risk remained associated with the outcome (ß = 0.173; p = 0.007), low levels of GSH at 18 months after postpartum. Likewise, we verified the difference in GSH levels according to the degree of suicide risk, observing a significant association between the differences in glutathione means in the group of women with moderate to high risk compared to the reference group (no suicide risk) (p = 0.009). Conclusion: Our findings suggest that GSH may be a potential biomarker or etiologic factor in women at moderate to high risk of suicide.

Ausência de acompanhamento familiar e fatores associados nos partos da zona urbana de uma cidade do sul do Brasil: fato ou ficção? / Absence of family support and associated factors in the urban births of a city in Southern Brazil: fact or fiction?

RESUMO Objetivo: Verificar a prevalência e identificar os fatores associados à ausência do acompanhante de parto em mulheres no sul do Brasil. Métodos: Trata-se de um estudo transversal, realizado com 466 parturientes, pertencentes a uma coorte de mulheres da zona urbana da cidade de Pelotas, RS. Aos 18 meses pós-parto, foi aplicado um questionário estruturado com dados sociodemográficos, gestacionais e questões relacionadas ao parto. Foi realizada regressão logística para ajustes de possíveis fatores de confusão. Resultados: A prevalência da ausência de acompanhante de parto entre as mulheres foi de 22,3%. As parturientes com até 8 anos de estudo (RP=2,0 [IC95% 1,1-3,8]), que não viviam com um companheiro (RP=2,3 [IC95% 1,2-4,3]), que realizaram o pré-natal no setor público (RP=1,9 [IC95% 1,0-3,7]) e que tiveram um parto via cesárea (RP=6,0 [IC95% 2,9-12,4]) apresentaram maior probabilidade de ausência de acompanhante de parto. Conclusão: Os resultados apontam evidências relevantes para o seguimento da verificação da presença do acompanhante de parto no sul do Brasil, indicando a necessidade de melhor aproveitamento e adesão desta prática. Além disso, a lei que aprova a presença do acompanhante de parto no Brasil parece não estar sendo colocada em prática de modo integral, desrespeitando um direito das parturientes e impactando nos benefícios para a saúde materno-infantil.

ABSTRACT Objective: To verify the prevalence and identify the factors associated with the absence of birth companions among women in Southern Brazil. Methods: This is a cross-sectional study carried out with 466 parturient women in a cohort of women from the urban area of the city of Pelotas, RS. At 18 months postpartum, a structured questionnaire was applied with sociodemographic, gestational data and questions related to childbirth. Logistic regression was performed to adjust for possible confounding factors. Results: The prevalence of the absence of a birth companion among women was 22.3%. Parturient women with up to 8 schooling years (PR=2.0 [95%CI 1.1-3.8]), who did not live with a partner (PR=2.3 [95%CI 1.2-4.3]), who performed their prenatal care in the public sector (PR=1.9 [95%CI 1.0-3.7]) and who had a cesarean delivery (PR=6.0 [95%CI 2.9-12.4]) were more likely to not have had a birth companion. Conclusion: The results shows relevant evidence for the verification of the presence of a companion in Southern Brazil, indicating the need for better use and adherence to this practice. In addition, the law that approves the presence of the birth companion in Brazil does not seem to be being fully implemented, disrespecting a right of parturient women and impacting the benefits for for maternal and child health.

Genetic Variations in Elements of the Oxytocinergic Pathway are Associated with Attention/Hyperactivity Problems and Anxiety Problems in Childhood.

Genetic alterations related to oxytocin system seem to influence the neurobiology of attention-deficit hyperactivity disorder and anxiety problems leading to greater functional, social and emotional impairment. Here, we analyzed the association of OXTR rs2254298 and CD38 rs6449182 variants with attention/hyperactivity problems and anxiety problems in children. The study enrolled 292 children and adjusted regression model revealed OXTR rs2254298 AA genotype as a risk factor for attention deficit/hyperactivity problems (PR: 2.37; PadjFDR = 0.006), attention problems (PR: 2.71; PadjFDR = 0.003) and anxiety problems (PR: 1.92; PadjFDR = 0.018). CD38 rs6449182 G allele showed as a risk factor for attention deficit/hyperactivity problems (PR: 1.56; PadjFDR = 0.028). Moreover, in silico approach for regulatory roles found markers that influence chromatin accessibility and transcription capacity. Together, these data provide genetic information of oxytocin in developmental and behavioral disorders opening a range of opportunities for future studies that clarify their neurobiology in childhood.

Are adolescents more likely to have antenatal anxiety disorders than adult women? A comparison between two samples.

BACKGROUND: The literature reports that teenage pregnancy is considered a risk factor for anxiety disorders (ADs). However, research on this topic is limited. This study aimed to investigate if pregnant adolescents presented a greater likelihood of having ADs by comparing two samples of pregnant women in a southern city of Brazil. We also observed the prevalence rates of antenatal ADs among adolescents and adult women. METHODS: In this cross-sectional study, we evaluated 1852 women from two different studies: 995 pregnant adolescents attending prenatal care in the public health system (convenience sample) and 857 pregnant women from a population-based study. We used the Mini International Neuropsychiatric Interview (MINI Plus) to assess antenatal ADs, using the Social Anxiety Disorder (SAD) and Generalized Anxiety Disorder (GAD) modules. The primary aim of this study was tested through multivariate analysis using Poisson regression. RESULTS: The prevalence of ADs was 11.0 % among pregnant adolescents and 13.8 % among adult pregnant women. Both samples presented similar rates of ADs (p = 0.065). In the adjusted analysis, maternal age did not predict antenatal ADs (PR = 0.97; p = 0.853). LIMITATIONS: Considering the particularities of each study where the samples came from, it was not possible to include other ADs such as panic disorder or phobias. CONCLUSIONS: Our findings suggest that pregnancy in adolescence does not increase the likelihood of antenatal ADs. However, we emphasize the importance of an adequate psychological screening and care in pregnancy in order to prevent possible psychiatric disorders.

Antenatal depression: Efficacy of a pre-post therapy study and repercussions in motor development of children during the first 18 months postpartum. Study: "Pregnancy care, healthy baby".

AIMS: To evaluate the efficacy of brief psychotherapeutic interventions of cognitive behavioral therapy to treat antenatal depression and verify the association between interventions and motor development of infants at 3 and 18 months of age. METHODS: Pre-post-intervention study nested a randomized clinical trial, both of which are extracts from a population-based cohort study of a southern Brazilian city. The major depressive episode was measured through Mini Plus, the severity of depressive symptoms by BDI-II and motor development using Bayley-III and AIMS. The follow-ups occurred during the gestational period (T2) and at 3 (T3) and 18 months (T4) after delivery. RESULTS: Data were analyzed from 336 women in the control group (not intervened) and 108 from the group of depressed women who received intervention for antenatal depression. The effectiveness of the interventions for a major depressive episode was around 80% for both models in the two follow-up stages (3 and 18 months postpartum). In addition, the children whose mothers received intervention presented 3.7 (95% CI 0.7-6.6) points higher in Bayley-III at 3 months old when compared to the children in the control group (p = 0.01). There was no difference between the two psychotherapy models tested, both being equally effective (p > 0.05). CONCLUSIONS: We found that the brief psychotherapeutic interventions of cognitive behavioral therapy for gestational depression were effective in causing remission of the condition both in the short and long term, besides indirectly causing benefits also to the children, with regard to their motor development.

Family perception of the symptoms of Obsessive-Compulsive Disorder patient and the family accommodation.

BACKGROUND: Family members tend to modify their routine by assisting or participating in the patient's rituals. These behaviors have been identified as family accommodation (FA). AIMS: The aim of this study was to describe the relationship between family accommodation of relatives of Obsessive-Compulsive Disorder (OCD) patients and their perceptions about the obsessions and compulsions of the patient. METHOD: This was a cross-sectional study with family members of Obsessive-Compulsive Disorder in a Southern Brazilian city. The family perception of the OCD symptoms and their accommodation were assessed through the Family Accommodation Scale for Obsessive-Compulsive Disorder - Interviewer-Rated (FAS-IR). RESULTS: The level of family accommodation was higher in those family members who lived with the patient when compared to those who did not live with them (p = .011). The obsessions associated with higher levels of family accommodation were: contamination (p < .001), hoarding/saving (p = .001), symmetry/exactness (p = .001), religious (p = .019), and diverse (p = .003). Regarding compulsions, the perception of all symptoms was associated with higher levels of family accommodation (p < .05). CONCLUSION: The family accommodation is present in family members of Obsessive-Compulsive Disorder patients, regardless of the type of obsessive/compulsive symptom perceived.

Evidence of validity of the revised Helping Alliance Questionnaire based on the internal structure in a Brazilian clinical sample.

The revised Helping Alliance Questionnaire (HAq-II) is among the most used instruments that measure therapeutic alliance. Despite its use in research, this instrument is not validated for the Brazilian population. The aim of this study was to explore the evidence of validity of the HAq-II based on the internal structure in a sample of Brazilian psychiatric patients. An ambulatory convenience sample of 204 patients with major depressive disorder (MDD) and 81 patients with obsessive-compulsive disorder (OCD) was randomized between two different types of treatment. The HAq-II was completed by patients (patient version) and by 33 therapists who performed the interventions (therapist version) between the second and third sessions. We used confirmatory factor analysis (CFA) to investigate two models: (1) a one-dimensional therapeutic alliance model and (2) a two-dimensional model considering the factors 'positive alliance' and 'negative alliance'. The internal consistency of the HAq-II was measured by Cronbach's alpha. To investigate discriminant validity, we used the t-test for independent samples, ANOVA and Pearson's correlation coefficient. The analysis showed that the best model of the instrument was one-dimensional. Cronbach's alpha for both versions displayed values above 0.89. The Brazilian version of the HAq-II presented properties similar to those found in the original version. However, studies related to the one-dimensional model with other samples are necessary.

Brief cognitive behavioral therapy in pregnant women at risk of postpartum depression: Pre-post therapy study in a city in southern Brazil.

BACKGROUND: Postpartum depression (PPD) affects a high number of women, often the first manifestation of a mood disorder that will occur later in life, bringing serious consequences for the patient and her offspring. Depression today is the leading cause of disability worldwide. The aim of this study was to evaluate the effectiveness of a preventive cognitive behavioral therapy (CBT) for PPD. METHODS: Pre-post therapy study, as part of a population-based cohort study. Pregnant women without a diagnosis of depression participated, who were divided into two groups: risk of depression (CBT) and a control group (without therapy). The preventive therapy consisted of six sessions of CBT, administered weekly. The Outcome Questionnaire (OQ-45) was used in all sessions. The Mini International Neuropsychiatric Interview and Beck Depression Inventory-II were used on three occasions. The final statistical analyses were performed by Poisson regression. RESULTS: The prevalence of PPD in the risk group was 5.5% and in the control group 2.2%, with no difference between the groups (PR 1.66 95% CI 0.44-6.18). The OQ-45 averages gradually reduced during the therapy sessions, indicating therapeutic progress. Schooling was an associated factor, both with the manifestation of PPD and with the greater effectiveness of the therapy. LIMITATIONS: Rate of 40.5% refusal to preventive treatment and absence of a group with similar characteristics in another therapy model. CONCLUSIONS: Brief cognitive behavioral therapy applied by mental health professionals with basic training was effective in preventing the manifestation of PPD.

Maternal-fetal attachment and perceived parental bonds of pregnant women.

BACKGROUND: The parental bond is characterized by the perception of care and protection received by parental figures throughout human development. During the gestational period, the intensity in which the woman manifests behaviors and feelings for the fetus was denominated maternal-fetal attachment (MFA). In this perspective, the literature indicates that there is association between MFA and the pregnant woman's perception about the bond established with her parents. AIMS: This study aimed to evaluate the association between MFA and perceived parental bonds of pregnant women in the city of Pelotas/RS (Brazil). STUDY DESIGN: This is a cohort study with 839 women during their gestational period. All women answered to the Parental Bonding Instrument to investigate the perceived parental bonds, and the MFA was assessed through the Maternal-Fetal Attachment Scale. RESULTS: The main results showed that perceived paternal overprotection was associated with a higher MFA after adjustment (B 2.00 CI95% 0.30; 3.70). Additionally, the pregnant women who were in the first trimester of pregnancy (p < 0.001), who did not live with a partner (p = 0.018), and who did not feel supported by the baby's father during pregnancy (p = 0.014) presented lower scores of MFA. CONCLUSION: This study showed the importance of the paternal role in the women's life, considering the perception of the bond with their father during their development, an adequate support by the father of the baby, and the presence of a partner during pregnancy. As a result, the paternal role may influence the feelings and behaviors of greater affection, care, and concern regarding the fetus.

Suicide risk and prematurity: A study with pregnant adolescents.

OBJECTIVE: To verify the association between mood and anxiety disorders, and suicide risk during pregnancy and their relationship with premature birth in a population of pregnant adolescents attending prenatal care in the public health system of Pelotas, a southern city in Brazil. METHODS: This was a cohort study with all pregnant adolescents attending antenatal public services in the urban area of Pelotas between October 2009 and May 2011. The first assessment occurred between the 20th and 22 nd week of pregnancy and the second occurred one month after delivery. We used the Mini International Neuropsychiatric Interview (MINI) to assess mood and anxiety disorders and suicide risk. RESULTS: A total of 645 pregnant women aged between 12 and 19 years old were interviewed. An anxiety disorder was present in 9.1% of the pregnant adolescent, and 28.5% had a mood disorder. The prevalence of suicide risk was 12.6%, and 15.3% of the babies were born premature. A multivariate analysis adjusted for maternal education, number of previous pregnancies and previous preterm birth indicated that adolescents who had suicide risk during pregnancy were approximately twice as likely to give birth prematurely when compared to those who were not diagnosed with suicide risk (PR 1.79; CI 1.06-3.03). CONCLUSION: Our findings suggest that pregnant adolescents who were at risk of suicide during pregnancy were more likely to have premature babies. It is important to pay attention to the mental health of this specific population to prevent obstetric complications and consequently improve the health of the children.

Generalized Anxiety Disorder, Depressive Symptoms and the Occurrence of Stressors Events in a Probabilistic Sample of Pregnant Women.

The aim of the study is to verify the association between GAD, the severity of depressive symptoms and stressors in pregnant women between the first and second trimester. Cross-sectional study, part of a cohort that followed 980 women during the gestational period of a city in southern Brazil. We performed bivariate analysis using the t-test and chi-square. The variables that presented p ≤ 0.20 were taken for multivariate analysis, through logistic regression, in order to control possible confounding factors. The Mini International Neuropsychiatric Interview Plus was used to evaluate GAD, the severity of depressive symptoms was investigated through the Beck Inventory of Depression II, and stress events according to the Social Readjustment Assessment Scale of Holmes e Rahe. The sample consisted of 980 women. Women with mild depression symptoms had 9.8 (IC95% 4.6;21.0) times more GAD, those with moderate symptoms had 27.5 (IC95% 12.5;60.0) times more GAD, and those with severe symptoms had 52.9 (IC95% 19.1;146.5) times more GAD when compared to pregnant women with no symptoms or minimal symptoms. Regarding the stressful events, the pregnant women who presented GAD had an increase of 1.0 (IC95% 1.0;1.1) point in the mean of occurrence of stressor events when compared to those without GAD. These findings highlight the need for prevention strategies and interventions to promote maternal mental health, which benefit the development of infants in the long term.

Suicide Risk and Mood Disorders in Women in the Postpartum Period: a Longitudinal Study.

Suicide associated with severe psychiatric illnesses is considered the leading cause of maternal deaths. We aimed to assess the suicide risk in women who experienced depressive or mixed episodes of mood change during the postpartum period and to determine which disorder is more related to suicide risk in the same period. We conducted a longitudinal study with 706 women whose children were born from April 2007 to May 2008 in a southern city in Brazil, and received prenatal care by the Brazilian National System of Public Health. The first assessment occurred during the prenatal period and the second within 30 to 60 days postpartum. The incidence of suicide risk was 10.9%. The odds of postpartum suicide risk were 6.50 (95% CI: 2.73; 15.48) higher in mothers with postpartum depression and 41.50 (95% CI: 12.11; 142.16) higher in those with mixed episodes than those who did not suffer from any mood disorder. Women with chronic episodes (who had depressive or mixed episodes during pregnancy and postpartum) were at increased odds of 4.94 (95% CI: 1.46; 16.69) of a postpartum suicide risk. The postpartum seems to be a critical period in the women's mental health. The impact of mental disorders in this period, especially mixed episodes, can increase the odds of a suicide risk onset. A good psychiatric evaluation and support during the prenatal and postpartum care may prevent the subsequent risk of suicide.

Thimerosal-containing vaccines and deficit in child development: Population-based study in southern Brazil.

BACKGROUND: The discussion on the safety of thimerosal-containing vaccines (TCVs) and their impact on child development it́s very relevant. METHODS: This is a cohort study with mother-child dyads who received prenatal care in the Unified Health System. The domains of motor, cognitive and language development were evaluated in children between 24 and 36 months of age. Data on vaccination were obtained through the child's immunization record. A linear regression analysis was carried out considering possible confounders. RESULTS: In bivariate analyses, motor and language development were associated with TCVs (p < 0.05). However, in the multivariate analysis, this association was not maintained (p > 0.05). These results indicate that the use of TCVs is not associated with child development. The importance of this study is summarized in transmitting relevant information regarding public health, based on reliable data.

Prevalence of mental health problems in preschoolers and the impact of maternal depression.

A large number of children of depressed mothers have one or more mental disorders. This study aimed to evaluate the impact of maternal depression on the mental health of 4-5-year-old children of adolescent mothers, according to the hypotheses generated from the model of accumulation. Between October 2009 and March 2011, all pregnant adolescents who received prenatal care from the public health system in Pelotas (southern Brazil) were invited to participate in the study and have been prospectively followed. Of these individuals, 413 participants were evaluated in the postpartum period and when the child was 2-3 years old and 4-5 years old (current stage). The Strengths and Difficulties Questionnaire was used to assess mental health problems in children, and the Mini International Neuropsychiatric Interview (MINI)-Plus version was used to assess maternal depression. We applied a structured modeling approach to examine the relations between three different hypothesized life course models (accumulation, critical period, and mobility) and maternal depression. After selecting the most appropriate model, we used a logistic regression analysis to assess the effect of depression on mental health problems in 4-5-year-old children of adolescent mothers. We used the Chi square test to estimate the prevalence of mental health problems in 4-5-year-old children. The longer the time of exposure to maternal depression, the greater the probability that the child would present behavioral problems. Investments in strategies to prevent mental disorders beginning in the gestational period are important.

Childhood trauma and depressive symptoms in pregnant adolescents in Southern Brazil.

OBJECTIVES: This study aimed to investigate the association between child maltreatment and depressive symptomatology during gestation in adolescents. METHODS: This was a cross-sectional study with pregnant adolescents aged 12 to 19 years. Data were collected with the Beck Depression Inventory, Childhood Trauma Questionnaire, and Mini International Neuropsychiatric Interview. RESULTS: Compared to adolescents who did not experience each type of neglect or abuse, experiencing them was associated with a higher proportion of depressive symptoms: emotional neglect PR = 1.4 (95% CI 1.1; 1.8); physical neglect PR = 1.7 (95% CI 1.3; 1.7); emotional abuse PR = 1.8 (95% CI 1.4; 2.2); and physical abuse PR = 1.3 (95% CI 1.1; 1.7). CONCLUSIONS: This study demonstrates the association between childhood experiences and mental health in adolescence, especially in vulnerable samples, such as pregnant adolescents. This finding reveals the importance of studying early trauma in life and enabling preventive help, especially in adolescents. High-quality evidence of perinatal mental health problems should be generated to make pregnancy safer for women in low- and middle-income countries.

The perception of parental bonding in pregnant adolescents and its association with generalized anxiety disorder.

BACKGROUND: The parental bonding is influenced by two dimensions: care and control or protection over the child of both parents. The lack of care during childhood may make the individual more susceptible to the onset of psychiatric disorders when adult. These psychiatric disorders when present during pregnancy may have a negative impact on the health of pregnant women and children. The aim of this study was to assess the association between generalized anxiety disorder (GAD) in pregnant adolescents and the perception of parental bonding. METHODS: This is a cross-sectional study with 871 pregnant women under the age of 19, receiving prenatal care in 47 Basic Health Units in the one city, Brazil. The generalized anxiety disorder was measured using the Mini International Neuropsychiatric Interview (MINI) and the perception of parental bonding in childhood using the Parental Bonding Instrument (PBI). RESULTS: The prevalence of GAD was 8.5%. Among all the parental bonding dimensions, only a perceived lack of maternal care under 16 years was associated with GAD. CONCLUSIONS: The results showed that only the perception of maternal bonding was associated with later GAD. It suggests that an adequate maternal bond is an essential component of psychological health.

Cognitive and language performance in children is associated with maternal social anxiety disorder: A study of young mothers in southern Brazil.

BACKGROUND: It has been shown that maternal mental health is associated with poorer skills development in the offspring. However, the evidence evaluating the association between social anxiety disorder (SAD) and cognitive or language development, is scarce. AIM: To evaluate the association between maternal SAD and performance in cognitive and language tests in 30-month old children. STUDY DESIGN: This was a cohort study involving young women evaluated since pregnancy. SUBJECTS: We evaluated 520 mother-child dyads who received prenatal medical assistance through the National Public Health System in a southern Brazilian city, from October 2009 to March 2011. OUTCOME MEASURES: We used the Mini Neuropsychiatric Interview Plus (MINI Plus) to assess SAD among young mothers. Cognitive and language performance in their offspring was analyzed using the Bayley Scales of Infant and Toddler Development - 3rd Edition. RESULTS: We found an association between maternal SAD and performance in cognitive and language tests. Children of mothers with SAD had in average 4.5 less points in the Bayley scale, when compared to those with mothers without SAD: in the cognitive (ß=-4.53 [95% CI -7.8; -1.1] p=0.008) and language subscales (ß=-4.54 [95% CI -9.0; -0.5] p=0.047). CONCLUSIONS: Our findings suggest that children with mothers suffering from SAD have poorer cognitive abilities and language skills.
