RESUMO

OBJECTIVE: to assess the effects of an intervention based on the Theater of the Oppressed in reducing school bullying. METHOD: a quasi-experimental study with 232 first-year high school students from two public schools in the city of Cuiabá, Mato Grosso State, Brazil. An intervention was performed with the Theater of the Oppressed, a theatrical methodology created by Augusto Boal and inspired by Paulo Freire's "Pedagogy of the Oppressed", in which one school composed the intervention group, and another school, the comparison group. Both groups were assessed for involvement in bullying situations before and after intervention. For data analysis, Poisson Regression models with random effect were used. RESULTS: intervention group presented a significant decrease in direct victimization (physical and verbal aggression). CONCLUSION: the Theater of the Oppressed represents an important strategy in reducing bullying victimization among school adolescents.

RESUMO

ABSTRACT Objective: To identify sociodemographic, physical activity, and physical fitness factors associated with flexibility. Methods: Cross-sectional study with 909 adolescents (486 girls) aged 14 to 19 years from the city of São José, Santa Catarina, Brazil. To evaluate flexibility, we used the sit and reach test. Sociodemographic and physical activity data were collected by a self-administered questionnaire. We analyzed muscle strength with manual dynamometry. Aerobic fitness was assessed with the modified Canadian aerobic fitness test, and physical activity with a questionnaire. We used multiple linear regression to identify the variables associated with flexibility, with a significance level of 5%. Results: For each additional centimeter in the girls' levels of flexibility, the boys were 2.94 cm less flexible. In addition, the increment of 0.12 kg/force in muscle strength levels increased the levels of flexibility in 1 cm. Conclusions: Lower levels of flexibility were associated with male adolescents and with reduced strength levels.

RESMO Objetivo: Identificar os fatores sociodemográficos, de atividade física e da aptidão física associados à flexibilidade. Métodos: Estudo transversal com 909 adolescentes (486 meninas) de 14 a 19 anos da cidade de São José, Santa Catarina, Brasil. A flexibilidade foi avaliada por meio do teste de sentar e alcançar. Os dados sociodemográficos e de atividade física foram levantados por meio de questionário autoadministrado. A força muscular foi analisada por meio da dinamometria manual. A aptidão aeróbia foi analisada por meio do teste canadense modificado de aptidão aeróbia, enquanto a atividade física foi avaliada por questionário. Utilizou-se regressão linear múltipla para identificar as variáveis associadas à flexibilidade, com nível de significância de 5%. Resultados: Verificou-se que a cada centímetro a mais nos níveis de flexibilidade nas meninas, os meninos tiveram 2,94 cm a menos de flexibilidade. Ademais, o incremento de 0,12 kg/força nos níveis de força muscular aumentou em 1 cm os níveis de flexibilidade. Conclusões: Menores níveis de flexibilidade estiveram associados aos adolescentes do sexo masculino. Além disso, menores níveis de flexibilidade foram diretamente associados aos adolescentes que apresentavam menores níveis de força.

RESUMO

ABSTRACT Objective: To analyze the contribution of subjective sleep need for daytime sleepiness in adolescents, and to compare questions about sleep, age and body mass index between adolescents who considered to sleep enough and those who reported the need for more sleep. Methods: This is a descriptive, epidemiological and cross-sectional study. Data collection was performed in August 2016, with 773 adolescents aged 14-19 years old, from Paranaguá, Paraná, Southern Brazil. The analysis included the following variables: time in bed, half-sleep phase, sleep need, social jetlag, daytime sleepiness, body mass index and physical activity. Results: The prevalence of adolescents with subjective need for sleep was 73.0%, with an average need of 1.7 extra hours of sleep. These adolescents woke up earlier (p<0.001) and slept less on school days (p<0.001). The need for more sleep was associated with higher daytime sleepiness scores (rho=0.480; p<0.001) and with later half-sleep phase (rho=0.200; p<0.001). No correlation was identified between the sleep need and time in bed (rho=-0.044; p=0.225). The subjective sleep need was the variable with the greatest explanatory power for daytime sleepiness (24.8%; p<0.001). In addition, the less adolescents practiced physical activity, the higher their daytime sleepiness scores (rho=-0.117; p<0.001). Conclusions: The subjective sleep need has an important role in explaining daytime sleepiness among adolescents. Adolescents who needed to sleep more reported waking up early and experienced sleep deprivation during class days; they also woke up later on the weekends and experienced more daytime sleepiness, compared to those who believed they had enough sleep.

RESUMO Objetivo: Analisar a contribuição da necessidade subjetiva de sono para a sonolência diurna em adolescentes e comparar questões sobre sono, idade e índice de massa corporal entre os adolescentes que consideram dormir o suficiente e os que julgam necessitar dormir mais. Métodos: Estudo descritivo, epidemiológico e transversal, cuja coleta de dados ocorreu em agosto de 2016 em 773 adolescentes de 14 a 19 anos de Paranaguá, PR, Brasil. As variáveis de análise foram tempo de cama, meia fase do sono e necessidade de mais horas de sono, além do jetlag social, sonolência diurna, índice de massa corpórea (IMC) e atividade física. Resultados: A prevalência de adolescentes com necessidade subjetiva de sono foi 73,0%, sugerindo precisar, em média, de 1,7 hora a mais de sono. Estes acordavam mais cedo (p<0,001) e dormiam menos nos dias de aula (p<0,001). A necessidade de dormir mais associou-se a maiores pontuações de sonolência diurna (rho=0,480; p<0,001) e com meia fase do sono mais tardia (rho=0,200; p<0,001). Não foi identificada correlação entre necessidade de sono e tempo de cama (rho=-0,044; p=0,225). A necessidade subjetiva de sono foi a variável com maior poder explicativo da sonolência diurna (24,8%; p<0,001). Além disso, quanto menos os adolescentes praticavam atividade física, maiores as pontuações de sonolência diurna (rho=-0,117; p<0,001). Conclusões: A percepção subjetiva de sono teve papel importante para explicar a sonolência diurna dos adolescentes. Os jovens que precisavam dormir mais relataram acordar mais cedo e apresentavam privação de sono durante os dias de aula, acordaram mais tarde no final de semana e apresentaram maior sonolência diurna, comparando-se aos que acreditavam dormir o suficiente.

RESUMO

Introducción: los trastornos funcionales gastrointestinales son motivo de consulta frecuente en Gastroenterología, y presentan un serio problema social y en la dinámica familiar. El síndrome de intestino irritable en la población pediátrica es poco diagnosticado, y el dolor abdominal crónico es motivo de consulta frecuente en la infancia y adolescencia. Objetivo: analizar los aspectos más actuales en su diagnóstico y tratamiento, y su relación con el dolor abdominal crónico. Métodos: se revisaron las bases documentales de PubMed, Scielo y Latindex y el Registro Especializado del Grupo Cochrane de datos relacionados con el síndrome de intestino irritable hasta diciembre de 2017, así como las guías de tratamiento postuladas por distintas organizaciones médicas, basadas en los criterios de Roma y de la Medicina Basada en la Evidencia. Desarrollo: se realizó una revisión del tema referido a la infancia, y se incluyeron concepto y patogénesis más aceptadas, así como los criterios de Roma establecidos para el diagnóstico. Se hizo énfasis en la etiología, diagnóstico clínico y pruebas diagnósticas. Se analizaron algunos aspectos del tratamiento. Conclusiones: el síndrome de intestino irritable es relativamente frecuente como causa de dolor abdominal crónico funcional, y el interrogatorio dirigido según los criterios de Roma es útil para su diagnóstico. La mayoría de los pacientes con síndrome de intestino irritable en la infancia deben ser atendidos en la atención primaria(AU)

Introduction: gastrointestinal functional disorders are a frequent reason for consultation in Gastroenterology services, and represent a serious social problem and in family dynamics. Irritable bowel syndrome in the pediatric population is poorly diagnosed, and chronic abdominal pain is a frequent reason for consultation in childhood and adolescence. Objective: to analyze the ultimate aspects in its diagnosis and treatment, and its relation with chronic abdominal pain. Methods: PubMed, Scielo and Latindex documentary databases and the Cochrane Specialized Register of data related to irritable bowel syndrome until December 2017 were revised, as well as the treatment guidelines presented by different medical organizations based on the criteria of Rome and of Evidence-Based Medicine. Development: a review of the subject referring to childhood was carried out, and the most accepted concept and pathogenesis were included, as well as Rome criteria established for the diagnosis. Etiology, clinical diagnosis and diagnostic tests were emphasized. Some aspects of the treatment were analyzed. Conclusions: Irritable bowel syndrome is relatively common as a cause of chronic functional abdominal pain, and questioning conducted according to Rome criteria is useful for diagnosis. The majority of patients with irritable bowel syndrome in childhood should be treated in the primary care level(AU)

RESUMO

OBJECTIVE: To assess the effects of muscle strength, as determined by grip strength, on changes in health status in adolescents. STUDY DESIGN: Risk variables included excess body fat, elevated fasting glucose, high blood pressure, elevated serum triglycerides, and low high-density lipoprotein cholesterol. Multinomial logistic regression was used to quantify the odds of experiencing health maintenance (no risk factors identified at either time point) or health improvement (presence of ≥1 baseline risk factor and fewer or no risk factors at follow-up) over a 2-year period. The primary exposure variable was grip strength normalized by body mass (normalized grip strength [NGS]), and previous cut-offs were used to determine whether adolescents were weak or strong. RESULTS: Adolescents who had low NGSs had a significantly greater prevalence of health decline or poor health persistence as compared with those who were strong (boys: 60.2% vs 15.3%; girls: 51% vs 21.9%; all P < .001). Moreover, adolescents who were strong had an increased adjusted odds for health maintenance (OR 3.54; 95% CI 1.80-6.97) and health improvement (OR 1.30; 95% CI 1.05-1.60), even after we adjusted for baseline fat-free mass index, cardiorespiratory fitness, and objectively measured physical activity. CONCLUSIONS: Greater NGS is associated with longitudinal health maintenance and health improvements in adolescents. Low NGS could be used as a prognostic indicator of cardiometabolic risk and to identify adolescents who would benefit most from lifestyle interventions to improve muscular fitness.
