Sentimentos e percepções de puérperas com relação à assistência prestada pelo serviço materno-infantil de um hospital universitário

OBJETIVOS: avaliar percepções e sentimentos de puérperas adultas e adolescentes, relacionados ao filho e a assistência materno-infantil, em hospital universitário de nível terciário. MÉTODOS: estudo transversal, envolvendo 180 puérperas, no Alojamento Conjunto (AC) e no Berçário Interno (BI) do Hospital das Clínicas da Faculdade de Medicina de Botucatu , entrevistadas no segundo e terceiro dia pós-parto e distribuídas em três grupos: adultas primíparas, adultas multíparas e adolescentes. Para comparação entre grupos e locais de internação utilizou-se o chi2 ou teste de Fisher. RESULTADOS: ultrasom obstétrico e cardiotocografia tiveram impacto positivo na emoção materna. Houve pouca diferença entre os grupos quanto aos sentimentos antes e após o parto, sendo felicidade, amor, responsabilidade, ansiedade e medo os mais freqüentes. A culpa predominou nas adolescentes do BI. As percepções relacionadas ao filho, a avaliação da assistência e equipe, não diferiram entre adultas e adolescentes. Nas duas enfermarias o relacionamento entre mães e cuidadores foi bom, as mães mostraram-se satisfeitas com a equipe e a assistência, mas o aleitamento materno foi pouco valorizado e poucas mães conheciam o médico. CONCLUSÕES: está ocorrendo um processo de humanização na assistência materno-infantil deste hospital universitário, mas alguns aspectos precisam ser melhorados, especialmente a valorização do aleitamento materno e a individualização no contato médico-paciente.

Práticas educativas de mães de bebês: efeitos de um programa de intervenção

This research aims to describe the effects of an intervention program focusing on parenting practices of mothers of babies by comparing pre- and post -test (intragroup comparison) performed with groups of adolescent mothers and adult mothers (intergroup comparison). Participants were 40 mothers, 20 adolescents and 20 adults. To collect data we used the Parenting Styles Inventory for Mothers of Babies (IEPMB), applied before and after the intervention, which is characterized for ten weekly meetings on topics related to the cycle of human development and parenting practices. The results showed significantly better educational practices for adolescent mothers compared to adult mothers especially in the first evaluation conducted. The intervention group was effective for most participants, adults and adolescents, who improved their parenting practices or remained appropriate. It discusses the importance of interventional groups to improve parenting practices of mothers of babies.

O inventário portage operacionalizado e o desenvolvimento de bebês

O acompanhamento do desenvolvimento de bebês implica na consideração de fatores de risco para os mesmos e na utilização de instrumentos que possibilitem a identificação de defasagens, comportamentais, visando à elaboração de intervenções pontuais junto a pais e outros cuidadores. O presente estudo prendendeu descrever variáveis distais e proximais do desenvolvimento de uma amostra de bebês, a partir de suas características peculiares, bem como das dos seus familiares e avaliar o repertório comportamental dos bebês, correlacionando-o com variáveis de risco como prematuridade, baixo peso ao nascer e filhos de mães adolescentes, comparando-o com bebês sem condição de risco identificada. Pretendeu, também, identificar comportamentos típicos nas áres do desenvolvimento avaliadas pelo inventário portage operacionalizado, mês a mês, durante o primeiro ano de vida, utilizando os critérios de estabilização, normalização e aparecimento destes comportamentos entre os meninos e meninas. Participaram do estudo 217 bebês que foram avaliados no decorrer do primeiro ano de vida, sendo que 33% eram prematuros, 28% filhos de mães adolescentes, 11% com baixo peso nascidos a termo, 3% sindrômicos ou filhos de mães portadoras de HIV+ e 25% do Grupo Controle, sem condições de risco identificado no nascimento. Os dados foram coletados a partir da entrevista inicial e da avaliação mensal do inventário. Os dados foram coletados a partir da entrevista inicial e da aplicação mensal do inventário portage operacionalizado (IPO), em um Centro de Psicologia Aplicada de uma universidade pública. Os desempenhos dos bebês no IPO e as condições de risco identificadas foram submetidas ao tratamento por meio do Statistic Package Social for Science (SPSS, versão 12.0). para a identificação de comportamentos típicos utilizaram-se os critérios de Estabilização...

Diferenças no desenvolvimento de meninos e meninas em condição de risco

This study aimed to evaluate the development of infants aged between 30 and 59 days, who presented some kind of risk factor threatening their development. Participated in the project 82 children, being 42 boys and 40 girls, presenting the following risk conditions: low birth weight, preterm birth or children of adolescent mothers. The protocol "Stimulation for kids" from "The Operationalized Portage Inventory" was administered. The girls presented a better performance in all conditions, however, no significant differences between genders were observed among the adolescent mothers' children. These results are consistent with those described in the literature and they indicate that the male population is more vulnerable to developmental damage. Public policies regarding early intervention to minimize the likelihood of future cognitive difficulties and consequently its impact in such population are essential.

Estilos e práticas parentais de mães adolescentes: um programa de intervenção

The aim of this study was to describe the styles and parenting practices of adolescent mothers to evaluate the influence of participation in an intervention program of parental practices. 14 adolescent mothers contributed with this research. For the evaluation was used the Inventory of Parenting Styles of Babies Mothers (IEPMB). The results showed that the participants before beginning the group had an average of Parental Style Good, after participating in the group participants had an average of Parenting Style Great. The intervention group presented effectively promoting the acquisition and/or maintenance of positive parenting practices and the reduction in negative practices.

Matemal separation affects cocaine-induced locomotion and response to novelty in adolescent, but not in adult rats

Maternal separation is known to exert long-term effects on both behavior and the neuroendocrine system. We investigated cocaine-induced locomotor activation as well as the locomotor and corticosterone response to forced novelty in maternally separated adolescent and adult rats. Maternal separation consisted of separating litters from their darns daily during 5 h from postnatal days 2 to 6. Control animals were subjected only to regular cage changes. Cocaine- (10 mg/kg, i.p.) and novelty-induced locomotion were recorded in an activity cage. After the animals were tested for behavioral response to novelty, trunk blood samples were collected and plasma corticosterone levels were determined by radioimmunoassay. Adolescent rats exposed to maternal separation exhibited an increased locomotor response to novelty and cocaine; corticosterone levels were lower in these adolescent animals, after exposure to the novel environment. These effects of materrial separation were not observed in rats that were tested as adults. Thus the maternal separation protocol produced enduring but transient changes in the behavioral response to cocaine and in the stress response to novelty. (C) 2004 Elsevier B.V. All rights reserved.

Differential behavioral and neuroendocrine effects of repeated nicotine in adolescent and adult rats

Despite the high prevalence of tobacco abuse among adolescents, the neurobiology of nicotine addiction has been studied mainly in adult animals. Repeated administration of this drug to adult rats induces behavioral sensitization. Nicotine activates the HPA axis in adult rats as measured by drug-induced increases in ACTH and corticosterone. Both behavioral sensitization and corticosterone are implicated in drug addiction. We examined the expression of behavioral sensitization induced by nicotine as well as the changes in corticosterone levels after repeated injections of nicotine in adolescent and adult animals. Adolescent and adult rats received subcutaneous (s.c.) injections of saline or 0.4 mg/kg of nicotine once daily for 7 days. Three days after the last injection animals were challenged with saline or nicotine (0.4 mg/kg; s.c.). Nicotine-induced locomotion was recorded in an activity cage. Trunk blood samples were collected in a subset of adolescent and adult rats and plasma corticosterone levels were determined by radioimmunoassay. Adult, but not adolescent, rats expressed behavioral sensitization. Pretreatment with nicotine abolished corticosterone-activating effect of this drug only in adult animals, indicating the development of tolerance at this age. Our results provide evidence that adolescent rats exposed to repeated nicotine display behavioral and neuroendocrine adaptations distinct from that observed in adult animals. (c) 2004 Elsevier B.V.

Exposure to chronic stress increases the locomotor response to cocaine and the basal levels of corticosterone in adolescent rats

Repeated exposure to stress results in augmentation in the locomotor response to psychostimulant drugs. We investigated the locomotor response to a novel environment or cocaine [ 10 mg/kg, intraperitoneally (i.p.)] and basal corticosterone levels in male adolescent rats exposed to chronic restraint or variable stress. Animals in the chronic restraint group were restrained for 1 hour daily. The chronic variable stress protocol consisted of exposure to different stressors twice a day in random order. Chronic restraint and variable stress regimens began simultaneously on postnatal day (P) 25 and were applied for 10 days. During this period the control group was left undisturbed except for cleaning the cages. Three days after the last exposure to stress, cocaine- and novelty-induced locomotion were recorded in an activity cage. Plasma corticosterone levels were determined in a subset of stress and control animals. Exposure to both chronic restraint and variable stress increased cocaine- induced locomotion and basal corticosterone plasma levels, while no change was observed in the response to a novel environment. Moreover, rats exposed to variable stress displayed the greatest locomotor response following a challenge dose with cocaine when compared to control and chronic restraint stress groups. This observation indicates that the stress regimen is relevant to the degree of stress-induced sensitization to cocaine.

Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats

We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were restrained for 2 hours once daily for 7 days. Three days after the last exposure to stress, the animals were challenged with saline or nicotine (0.4 mg/kg subcutaneously). Nicotine-induced locomotion was recorded in an activity cage. Trunk blood samples were collected in a subset of adolescent and adult rats and plasma corticosterone levels were determined by radioimmunoassay. Exposure to stress did not affect the nicotine-induced locomotor- or corticosterone-activating effects in both ages.
