No. of bitstreams: 1 Mariana Reichelt Chemello_.pdf: 4802071 bytes, checksum: 39b3bf16c4e97b7229684d2fa973e3a9 (MD5) Previous issue date: 2015-08-07 / Nenhuma / Esta dissertação de mestrado trata sobre a ansiedade materna e relação mãe-bebê, sendo composta de dois artigos, um teórico e outro empírico. No artigo teórico, intitulado “Ansiedade Materna e Maternidade: Uma Revisão Sistemática da Literatura” foi realizada uma revisão sistemática da literatura especializada, a fim de identificar e analisar a produção científica sobre ansiedade materna e maternidade, publicada no período de janeiro de 2009 a dezembro de 2014. Os achados demonstram a ausência de um instrumento específico para avaliar a ansiedade materna, e referem a importância de identificar a ansiedade no período pré-natal, como medida preventiva e protetiva para a saúde mental das mães, desenvolvimento do bebê e qualidade da relação dessa díade. No artigo empírico, intitulado “Ansiedade materna e relação mãe bebê: um estudo qualitativo”, foi realizada uma pesquisa de abordagem qualitativa com delineamento de Estudo de Casos Múltiplos. O objetivo foi investigar o fenômeno da ansiedade materna e sua manifestação em mães de bebês com idades entre seis e 12 meses, buscando identificar sua repercussão na relação mãe-bebê. Desse estudo participaram quatro díades mãe-bebê, em que as mães apresentaram ansiedade leve ou moderada. Em todos os casos analisados observou-se que a ocorrência de ansiedade materna no período da gravidez e nos primeiros cuidados com o recém-nascido, repercutiu de alguma forma na relação mãe-bebê. Os casos apresentados corroboram os achados da revisão de literatura que evidenciam que a ansiedade pode estar relacionada com complicações na gravidez e no pós-parto, com dificuldades nos primeiros cuidados com o recém-nascido, fatores estressantes durante a gravidez e no puerpério, como perdas e luto. Considerando a importância de detectar sinais ou sintomas de ansiedade já no período gestacional, salienta-se a necessidade de novos estudos com ênfase na identificação precoce desse fenômeno, além da importância de desenvolver e avaliar programas de intervenção para o controle e o manejo da ansiedade das mães, visando à prevenção e promoção da saúde mental materno-infantil. / This dissertation deals with maternal anxiety and mother-child relationship, and is composed by two articles, one theoretical and one empirical. In the theoretical article, entitled "Maternal Anxiety and Motherhood: A Systematic Literature Review", a systematic review of the literature was conducted in order to identify and analyze the scientific literature about maternal anxiety and motherhood, published from January 2009 to December 2014. The findings demonstrate the absence of a specific instrument for assessing maternal anxiety and state the importance of identifying anxiety in the prenatal period as a preventive and protective measure for the mental health of mothers, for the baby development and to improve the quality of the relationship of this dyad. In the empirical article, entitled "Maternal anxiety and mother-child relationship: a qualitative study," a qualitative research approach with delineation of Multiple Cases Studies was carried out. The objective was to investigate the phenomenon of maternal anxiety and its manifestation in mothers of babies aged between six and 12 months, trying to identify its impact on the mother-child relationship. In this study participated four mother-child dyads, whose mothers had mild or moderate anxiety. In all these cases it was found that the occurrence of maternal anxiety in the period of pregnancy and early care newborn, reflected somehow in the mother-child relationship. The presented cases corroborate the literature review that shows that anxiety may be related to complications in pregnancy and postpartum, with difficulties in the early care of the newborn, stressors during pregnancy and postpartum, as losses and mourning. Considering the importance that either signs or symptoms of anxiety have during pregnancy, it highlighted the need for further studies with emphasis on the early identification of this phenomenon and the importance of developing and evaluating intervention programs for the control and management of anxiety in the mothers, aiming at prevention and promotion of maternal and child mental health.

Representação de vínculo parental, depressão, ansiedade materna e traumatismo dentário em pré-escolares de uma área adscrita do Município de Porto Alegre / Representation of parental bonding, depression, maternal anxiety and traumatic dental injuries among South Brazilian preschool children

Bonfadini, Inaia January 2013 (has links)
Uma alta prevalência de traumatismo dentário (TD) tem sido relatado nas últimas décadas em um panorama global. Os estudos apontam diferentes fatores associados ao TD em dentes decíduos, entretanto as varíaveis psicológicas maternas e seu papel no contexto do TD de crianças em idade pré-escolar devem ser melhor elucidadas. Objetivo: O objetivo desta dissertação foi descrever a prevalência e identificar fatores associados ao TD de pré-escolares de uma área adscrita no município de Porto Alegre, RS. Métodos: Estudo transversal analítico. Participaram deste estudo 163 crianças em idade pré-escolar, moradoras de áreas adstritas de unidades básicas de saúde de um hospital público de referência no município de Porto Alegre, RS. A amostragem foi aleatória por conglomerado, mantendo a proporção de nascidos vivos em 2008 em cada unidade. A coleta de dados foi domiciliar e ocorreu entre dezembro de 2011 a fevereiro de 2013. Três examinadoras previamente treinadas e calibradas (kappa ≥ 0,8) realizaram exames clínicos em todas as crianças da amostra para coletar dados sobre TD e maloclusão.Um questionário foi aplicado junto às mães, a fim de coletar dados socioeconômicos bem como questões relativas a hábitos bucais deletérios e à etiologia e local de ocorrência do TD. O índice utilizado para TD foi o Children’s Dental Health Survey criteria. Os sintomas de ansiedade e depressão materna foram avaliados através dos inventários Beck de ansiedade e inventário Beck de depressão; o Parental Bonding Index foi utilizado para aferir vínculo parental. A associação de TD e seus possíveis indicadores de risco foram avaliados através de regressão logística multinominal utilizando o software SPSS 16.0. A pesquisa foi aprovada pelo Comitê de Ética do Grupo Hospitalar Conceição. Resultados: Uma alta prevalência de TD foi encontrada na população em estudo (49,8%), sendo 28,4% trauma somente em esmalte. Não foi encontrada associação de TD a nenhuma variável psicológica materna. Entretanto, nível educacional e número de filhos, bem como número de moradores na residência, idade e atividade laboral materna nos primeiros dois anos de vida da criança estiveram associados ao TD de dentes decíduos na amostra selecionada. Características clínicas das crianças como overjet e mordida cruzada também mostraram associação com TD. Conclusões: O presente estudo aponta que o traumatismo dentário em dentes decíduos é um agravo bastante prevalente, tendo associação com características oclusais e fatores socioeconômicos maternos. / An increased prevalence of traumatic dental injury (TDI) has been reported in the last few decades in worldwide. Studies indicate different factors associated with TDI in primary teeth, however maternal psychological variables and their role in the context of TDI children in preschool children should be better elucidated. Objective: The aim of this study was to identify associated factors with dental trauma in preschool children in the city of Porto Alegre, RS, Brazil. Methods: Cross sectional study. The study included 163 preschool children living in areas attached to basic health units in of a public referral hospital in Porto Alegre, RS, Brazil. The sampling was randomized, keeping the proportion of live births in 2008 in each unit. Data collection was done from December 2011 to February 2013 in the residence of the sampled households. Three previously trained and calibrated examiners (kappa ≥ 0.8) realized clinical examinations on all children in the sample to collect data on TDI and malocclusion. The mothers answered a questionnaire to collect sociodemographic data, and questions about oral habits, etiology and place of occurrence TDI. The index TDI was recorded according to the Children’s Dental Health Survey criteria. Symptoms of maternal anxiety and depression were assessed using the Beck Anxiety Inventory and Beck Depression Inventory; the Parental Bonding Index was used to evaluate parental bonding. The association of dental injuries and their possible risk factors was estimated using multinomial logistic regression using the SPSS 16.0 software. The study was approved by the ethics committee of the Hospital Group Conceição. Results: A high prevalence of dental trauma was found in the study population (49.8%), with 28.4% at the enamel level. There was no association of dental trauma to any maternal psychological variable. However, educational level and number of siblings as well as number of residents living in the same house, age and maternal work activity during the first two years of life of the children was associated with dental trauma in deciduous teeth in the selected sample. Clinical characteristics of children as overjet and crossbite also were associated to the presence of trauma. Conclusions: This study indicates that dental trauma in primary teeth is a fairly prevalent grievance, having association with occlusal characteristics and maternal socioeconomic factors.

Disrupting the impact of socio-contextual disadvantage on school readiness skill attainment among preschool children: The role of Head Start attendance

Callahan, Kristin Leigh 14 May 2010 (has links)
Created in 1965, Head Start is the longest running national school readiness program in the United States. Head Start was developed to improve children's social and academic readiness for kindergarten and to reduce the academic achievement gap between impoverished and more affluent children. However, questions about the effectiveness of Head Start have trouble the program since its inception. Head Start children often experience considerably more sociocontextual risk, specifically in the form of more economic disadvantage, maternal psychological distress, and dangerous neighborhoods. The goal of the present study was to evaluate the extent to which attending Head Start buffers children from some of the harmful effects of sociocontextual risk on their acquisition of academic and social school readiness skills. Socio-contextual risk factors were largely unrelated to the school readiness skills. Only mothers' reports of anxiety were significantly associated with slower rates of increase in children's PPVT scores, suggesting that mothers who are more anxious have children who are not developing receptive vocabulary scores as quickly as children whose mothers have fewer anxiety symptoms. Head Start did not buffer the impact of socio-contextual risk on children's attainment of school readiness skills. A secondary goal of the present study was to validate mothers' reports of neighborhood danger with interviewer impressions of neighborhood safety and objective crime reports. Interviewer impressions correlated significantly with mothers' reports of neighborhood danger and official crime statistics. Interestingly, official crime statistics were not correlated with mothers' reports of neighborhood danger, but were correlated with interviewer impressions. Interviewers may provide a valuable objective perspective of characteristics of the neighborhood. This sample was not intended to explore the effects of natural disasters on household structures, maternal psychopathology, or children's academic development. However, results clearly highlighted the need to empirically consider the specific challenges associated with lowincome families after a natural disaster. Study implications and promising directions for future research are discussed.

Os fatores ambientais que podem afetar o processamento facial e o reconhecimento emocional ao longo do curso de desenvolvimento tamb?m s?o pouco compreendidos. No entanto, acredita-se que as experi?ncias iniciais, particularmente envolvendo exposi??o repetida a faces emocionais dos cuidadores, influenciem esse curso. O objetivo deste estudo foi investigar os correlatos neurais do processamento de faces emocionais em lactentes usando a espectroscopia funcional no infravermelho pr?ximo (fNIRS), e examinar a poss?vel influ?ncia das experi?ncias emocionais iniciais dos lactentes, indiretamente medida pela investiga??o de sintomas de ansiedade materna. Foram avaliadas 29 crian?as de 5 meses de idade e suas m?es, recrutadas de uma amostra da comunidade de Boston, EUA. A ansiedade materna foi avaliada usando o componente tra?o do Invent?rio de Ansiedade Tra?o-Estado (STAI-T). Os lactentes observaram imagens visuais est?ticas de faces femininas retratando express?es de alegria e medo, enquanto as respostas hemodin?micas corticais foram medidas usando fNIRS. As respostas de oxihemoglobina (oxiHb) e deoxihemoglobina (deoxiHb) nas ?reas frontais, parietais e temporais foram comparadas entre as faces emocionais, e entre filhos de m?es com n?veis altos e baixos de sintomas de ansiedade. Os resultados demonstraram efeito principal significativo da emo??o (p=0,022), evidenciado pelo aumento na concentra??o de oxiHb para faces de alegria em compara??o a faces de medo. Ademais, observou-se efeito principal significativo da regi?o (p=0,013), induzido por maior concentra??o de oxiHb nas regi?es corticais temporais em rela??o ?s regi?es corticais frontais (p=0,031). Al?m disso, houve uma intera??o significativa entre emo??o, hemisf?rio e ansiedade (p=0,037). As an?lises revelaram que filhos de m?es com alta ansiedade demonstraram uma resposta hemodin?mica significativamente elevada no hemisf?rio esquerdo para faces de alegria, em compara??o com faces de medo no hemisf?rio direito (p=0,040) e esquerdo (p=0,033). Os resultados indicam que lactentes de 5 meses discriminaram faces de alegria em compara??o com faces de medo, evidenciado pela maior ativa??o para a primeira. A maior ativa??o nas regi?es temporais em rela??o ?s ?reas frontais foi discutida em rela??o ? ontog?nese do processamento facial e ?s redes neurais de reconhecimento emocional. A resposta mais acentuada, comparando faces de alegria e medo observada nos filhos de m?es com alta ansiedade, pode estar relacionada a altera??es no ambiente emocional dessas crian?as em compara??o com os filhos de m?es com baixa ansiedade. Assim, os n?veis de ansiedade materna parecem moderar as respostas cerebrais hemodin?micas das crian?as ?s faces emocionais. / The neural bases of facial emotion processing in infancy are largely unknown. The environmental factors that may impact facial processing and emotion recognition along the developmental course are also not clearly understood. However, early experiences, particularly involving consistent exposure to familiar caregiver faces, are believed to influence this course. The aim of this study was to investigate the neural correlates of infants? emotional face processing using functional near-infrared spectroscopy (fNIRS), and examine the potential influence of infants? early emotional experiences, indirectly measured by investigating maternal anxiety symptoms. Participants were 29 typically developing 5-monthold infants and their mothers, recruited from a community sample from the Boston greater area, MA, USA. Maternal anxiety was assessed using the trait component of the State-Trait Anxiety Inventory. Infants observed static visual images of a female model portraying happy and fearful expressions, while hemodynamic brain responses were measured using fNIRS. The oxyhemoglobin (oxyHb) and deoxyhemoglobin (deoxyHb) responses over frontal, parietal and temporal areas were compared for the emotional expressions in infants of mothers reporting low and high levels of anxiety symptoms. Results revealed a significant main effect of emotion (p=.022), driven by greater oxyHb concentration responses for happy compared to fearful faces. There was also a main effect of region (p=.013) induced by a significantly greater oxyHb concentration in temporal compared to frontal cortical regions (p=.031). Additionally, a significant three-way interaction between emotion, hemisphere and anxiety was observed (p=.037). Planned comparisons revealed that infants of high-anxious mothers showed significantly greater left hemispheric activation of oxyHb to happy faces when compared with right (p=.040) and left (p=.033) hemispheric activation of oxyHb to fearful faces. These findings possibly indicate that 5-month-olds can discriminate happy from fearful faces, evinced by the greater activation for the former. The greater activation in temporal as compared to frontal areas was discussed in relation to the ontogenesis of face processing and emotion recognition neural networks. The enhanced response to happy versus fearful faces observed in infants of high-anxious mothers can be related to the presumed altered emotional environment experienced by these infants, compared to that of infants of low-anxious mothers. Therefore, maternal anxiety levels appeared to moderate infants? hemodynamic brain responses to emotional faces.

Maternal mood and anxiety disorders and child school readiness: a Manitoba population-based study

Comaskey, Brenda 15 April 2015 (has links)
Title: Maternal Mood and Anxiety Disorders and Child School Readiness: A Manitoba Population-Based Study Objective: This study examined the relationship between several features of maternal Mood/Anxiety – timing, recurrence/persistence and severity – and child development on five key areas of school readiness at kindergarten, controlling for health, demographic and socio-economic factors. Methods: Using administrative data to further understand these relationships at a population level and over time, 18,331mother-child pairs were linked using a unique identifier. Maternal Mood/Anxiety was defined using the number of physician visits for mood and anxiety disorders and the number of prescriptions filled for antidepressants or sedatives/hypnotics. The outcome measures were child scores on five domains of the Early Development Instrument, a population-level tool for determining readiness for school at an aggregate level. Structural equation modeling was used to examine the relationship between maternal Mood/Anxiety and child outcomes for individual time periods, Mood/Anxiety recurrence/persistence and Mood/Anxiety severity. Infant health at birth, the family/socio-economic environment, child age and child gender were also entered into the models. Stratified analysis was undertaken to determine whether SES moderates the relationship between Mood/Anxiety and child outcomes. Results: Maternal Mood/Anxiety had a modest significant negative association with EDI scores, particularly for social, emotional and physical development. Prenatal and recurrent Mood/Anxiety were associated with lower scores on all five outcome domains. The influence of maternal Mood/Anxiety was mediated by the family environment, which had a strong, significant association with the outcomes, particularly for language and cognitive development. Infant health at birth was significantly associated with child outcomes, particularly for physical health. Socio-economic status (SES) was a moderator of the relationship between Mood/Anxiety and child outcomes. Conclusion: Using administrative data to define maternal mood and anxiety disorders is a sensitive measure to detect differences in five key areas of child development, particularly for social, emotional and physical outcomes. Family-related variables had a much stronger relationship with child outcomes than mood and anxiety disorders. Findings from this study can be used to design, implement and evaluate high quality clinical, program and policy interventions to support mothers and families and the healthy development of their children.
