Eating habits and psychopathology: translation, adaptation, reliability of the Nutrition Behavior Inventory to Portuguese and relation to psychopathology

Objective: The Nutrition-Behavior Inventory (NBI) is a self-administered instrument that allows eating habits to be correlated with psychopathological symptoms. The objective was to translate and adapt the NBI to Portuguese, and test the Portuguese NBI’s reliability. The second aim was to verify its sensitivity for identification of risk factors in terms of behavior/eating habits in children and adolescents. Methods: The NBI was translated, adapted, and back-translated. The Portuguese version of the NBI was then applied (N = 96; 9-12 years). In order to verify the internal consistency, Cronbach’s alpha was used. The psychopathological indicators of the participants were accessed using the Child Behavior Checklist (CBCL). The mean CBCL scores were analyzed in relation to the NBI data (cutoff point: ≥ 30 with indicators, and < 30 without). Results: Internal consistency was high (Cronbach’s alpha = 0.89) for the NBI. The CBCL scores correlated significantly with NBI (> 30) on the following: anxiety and depression (p = 0.041), social difficulties (p = 0.028), attention problems (p = 0.001), aggressive behavior (p = 0.015); ADHD (p < 0.001), and conduct problems (p = 0.032). Conclusion: The present results indicate that the NBI is a reliable instrument. The NBI can be useful for evaluating psychopathological symptoms related to the eating habits and behaviors of children and adolescents.

Gender-related pathways for behavior problems in the offspring of alcoholic fathers

The objective of the present study was to examine gender differences in the influence of paternal alcoholism on children's social-emotional development and to determine whether paternal alcoholism is associated with a greater number of externalizing symptoms in the male offspring. From the Mannheim Study of Risk Children, an ongoing longitudinal study of a high-risk population, the developmental data of 219 children [193 (95 boys and 98 girls) of non-alcoholic fathers, non-COAs, and 26 (14 boys, 12 girls) of alcoholic fathers, COAs] were analyzed from birth to the age of 11 years. Paternal alcoholism was defined according to the ICD-10 categories of alcohol dependence and harmful use. Socio-demographic data, cognitive development, number and severity of behavior problems, and gender-related differences in the rates of externalizing and internalizing symptoms were assessed using standardized instruments (IQ tests, Child Behavior Checklist questionnaire and diagnostic interviews). The general linear model analysis revealed a significant overall effect of paternal alcoholism on the number of child psychiatric problems (F = 21.872, d.f. = 1.217, P < 0.001). Beginning at age 2, significantly higher numbers of externalizing symptoms were observed among COAs. In female COAs, a pattern similar to that of the male COAs emerged, with the predominance of delinquent and aggressive behavior. Unlike male COAs, females showed an increase of internalizing symptoms up to age 11 years. Of these, somatic complaints revealed the strongest discriminating effect in 11-year-old females. Children of alcoholic fathers are at high risk for psychopathology. Gender-related differences seem to exist and may contribute to different phenotypes during development from early childhood to adolescence.

Ambiente familiar e transtorno de déficit de atenção e hiperatividade

OBJETIVO: Analisar fatores associados a transtorno de déficit de atenção e hiperatividade em crianças. MÉTODOS: Estudo longitudinal sobre problemas de comportamento em crianças escolares de São Gonçalo, RJ, em 2005. Foram analisados 479 escolares da rede pública selecionados por amostragem por conglomerados em três estágios. Foi utilizada a escala Child Behavior Checklist para medição do desfecho. Foi aplicado um questionário para pais/responsáveis acerca dos fatores de exposição analisados: perfil da criança e da família, variáveis de relacionamento familiar, violências físicas e psicológicas. O modelo regressão log-binomial com enfoque hierarquizado foi empregado para a análise. RESULTADOS: Quociente de inteligência mais alto associou-se inversamente à frequência do transtorno (RP = 0,980 [IC95% 0,963;0,998]). A prevalência de transtorno nas crianças foi maior quando havia disfunção familiar do que entre famílias com melhor forma de se relacionar (RP = 2,538 [IC95% 1,572;4,099]). Crianças que sofriam agressão verbal pela mãe apresentaram prevalência 3,7 vezes maior do que aquelas não expostas a essa situação no último ano (RP = 4,7 [IC95% 1,254;17,636]). CONCLUSÕES: Relações familiares negativas estão associadas aos sintomas de transtorno de déficit de atenção e hiperatividade. Sua associação com quociente de inteligência reitera a importância da base genética e ambiental na origem do transtorno.

Fatores associados a sintomas de transtornos alimentares entre escolares da rede pública da cidade do Salvador, Bahia

OBJETIVO: Identificar prevalência e fatores associados aos sintomas de transtornos alimentares entre escolares. MÉTODOS: Estudo transversal envolvendo 365 escolares, de 7 a 14 anos de idade, do ensino fundamental de Salvador/BA. Aplicou-se nos escolares < 12 anos o Teste de Comportamentos Alimentares e Imagem Corporal e, naqueles > 13 anos de idade, o Teste de Atitudes Alimentares-26, o Teste de Investigação Bulímica de Edinburgh e o Teste de Imagem Corporal. O Child Behavior Checklist foi aplicado para todos os escolares. Coletaram-se dados antropométricos e alimentares, sobre estilo de vida, demográficos, socioeconômicos e puberais. Na análise estatística utilizou-se regressão de Poisson. RESULTADOS: Sintomas de transtornos alimentares estavam presentes em 23% dos escolares. Idade (RP: 1,25; IC95%: 1,11-1,40), insatisfação com imagem corporal (RP: 4,23; IC95%: 2,53-7,08), problema de comportamento de internalização (RP: 1,78; IC95%: 1,11-2,85), substituição das refeições por consumo de balas (RP: 2,14; IC95%: 1,24-3,69), maior consumo de frutas e outros vegetais (RP: 2,49; IC95%: 1,55-3,99) e escolaridade materna de 5ª a 8ª série (RP: 1,95; IC95%: 1,06-3,58) associaram-se ao aumento da ocorrência dos sintomas de transtornos alimentares. CONCLUSÃO: Observou-se alta prevalência de sintomas de transtornos alimentares entre os escolares; fatores sociodemográficos e comportamentais estavam associados ao evento.

Electrochemical behavior of parent and photodegradation products of some selected pesticides

Electrochemical behavior of pesticides is extensively studied, but little attention has been given to the study of their degradation products (by-products) by electrochemical methods. However, the degradation products of pesticides can be even more toxic then the parent products and such studies should be encouraged. Therefore, the objective of this work was to evaluate the electroactivity of by-products of imazaquin, methylparathion, bentazon and atrazine, generated by UV irradiation and measured using cyclic and differential pulse voltammetry and UV-visible absorption spectrophotometry. Results have shown that several by-products exhibit electroactivity, allowing, in some cases, the simultaneous determination of both parent and degradation products.

Sedentary behavior in Brazilian children and adolescents: a systematic review

ABSTRACT OBJECTIVE To describe the methodological characteristics of the studies selected and assess variables associated with sedentary behavior in Brazilian children and adolescents. METHODS For this systematic review, we searched four electronic databases: PubMed, Web of Knowledge, LILACS, SciELO. Also, electronic searches were applied in Google Scholar. A supplementary search was conducted in the references lists of the included articles and in non-indexed journals. We included observational studies with children and adolescents aged from three to 19 years developed in Brazil, presenting analyses of associations based on regression methods and published until September 30, 2014. RESULTS Of the 255 potential references retrieved by the searches, 49 met the inclusion criteria and composed the descriptive synthesis. In this set, we identified a great number of cross-sectional studies (n = 43; 88.0%) and high methodological variability on the types of sedentary behavior assessed, measurement tools and cut-off points used. The variables most often associated with sedentary behavior were “high levels of body weight” (in 15 out of 27 studies; 55.0%) and “lower level of physical activity” (in eight out of 16 studies; 50.0%). CONCLUSIONS The findings of this review raise the following demands to the Brazilian agenda of sedentary behavior research geared to children and adolescents: development of longitudinal studies, validation of measuring tools, establishment of risk cut-offs, measurement of sedentary behavior beyond screen time and use of objective measures in addition to questionnaires. In the articles available, the associations between sedentary behavior with “high levels of body weight” and “low levels of physical activity” were observed in different regions of Brazil.

Proposal Intensity Adequacy of Expiratory Effort and Heart Rate Behavior During the Valsalva Maneuver in Preadolescents

Background: When performing the Valsalva maneuver (VM), adults and preadolescents produce the same expiratory resistance values. Objective: To analyze heart rate (HR) in preadolescents performing VM, and propose a new method for selecting expiratory resistance. Method: The maximal expiratory pressure (MEP) was measured in 45 sedentary children aged 9-12 years who subsequently performed VM for 20 s using an expiratory pressure of 60%, 70%, or 80% of MEP. HR was measured before, during, and after VM. These procedures were repeated 30 days later, and the data collected in the sessions (E1, E2) were analyzed and compared in periods before, during (0-10 and 10-20 s), and after VM using nonparametric tests. Results: All 45 participants adequately performed VM in E1 and E2 at 60% of MEP. However, only 38 (84.4%) and 25 (55.5%) of the participants performed the maneuver at 70% and 80% of MEP, respectively. The HR delta measured during 0-10 s and 10-20 s significantly increased as the expiratory effort increased, indicating an effective cardiac autonomic response during VM. However, our findings suggest the VM should not be performed at these intensities. Conclusion: HR increased with all effort intensities tested during VM. However, 60% of MEP was the only level of expiratory resistance that all participants could use to perform VM. Therefore, 60% of MEP may be the optimal expiratory resistance that should be used in clinical practice.

Therapeutic play in preparing for surgery: behavior of preschool children during the perioperative period

Objective:to describe the behavior of children during the instructional session of therapeutic play (ITP) in the preoperative period and to verify the behavior presented by them during the perioperative period. Methods: Exploratory descriptive study with a quantitative approach, developed in a large private hospital in Sao Paulo, in which the behaviors presented by 30 children between three and five years old, undergoing minor surgery were seen at the hospital during the session of TP and in the surgical center, from admission to awaken from anesthesia. Results: Most children participated in the ITP session (21; 70%), entered the surgical room spontaneously (22; 73.3%) without resisting mother separation (24; 80%), collaborating with the anesthetic procedure (16; 53.3%) and quietly awakening from anesthesia (26; 87%). Conclusion: The use of ITP led the child to understand the surgical procedure, making it less traumatic.


Child care and health rights: perspectives of adolescent mothers

AbstractOBJECTIVETo analyze child health care and the defense of their rights from the perspective of adolescent mothers.METHODSAn exploratory study with qualitative thematic analysis of data, based on conceptual aspects of care and the right to health, from semi-structured interviews with 20 adolescent mothers ascribed by Family Health teams.RESULTSMaternal reports indicate that child health care requires responsibility and protection, with health practices that promote child advocacy. Gaps in assistance which preclude the full guarantee of the right to child health care were also highlighted.CONCLUSIONThe right to health care assumed different meanings, and the forms to guarantee them were linked to individual behavior in detriment to broader actions that consider health as a social product, connected to the guarantee of other fundamental rights.
