RESUMO

This article aims to review systematically the evidence on nutritional assessment techniques and parameters used to determine the nutritional status of children and adolescents. The literature review and the selection of publications were performed using the Medline, Lilacs, SciELO, Embase, personal files. 17 studies were identified, 7 addressed the anthropometric indices as the main outcome, 7 analyzed the growth and development of children and adolescents through growth curves, and the remainder surveyed body composition. In general, all met the quality criteria, unless 6 of the articles who did not discuss the limitations. The literature review suggests several techniques and parameters that can be applied to determine the nutritional status of children and adolescents from different countries. Growth graphs are essential to assess the health of children, but depend greatly of the growth tables used. Although BMI can be practical, it does not distinguish body fat from lean mass. The best interpretation of anthropometry will depend of valid reference values for age range of the study population. BIA is a quick feasible method, but the measurement has some various nationalities.

RESUMO

Abstract This article aims to review systematically the evidence on nutritional assessment techniques and parameters used to determine the nutritional status of children and adolescents. The literature review and the selection of publications were performed using the Medline, Lilacs, SciELO, Embase, personal files. 17 studies were identified, 7 addressed the anthropometric indices as the main outcome, 7 analyzed the growth and development of children and adolescents through growth curves, and the remainder surveyed body composition. In general, all met the quality criteria, unless 6 of the articles who did not discuss the limitations. The literature review suggests several techniques and parameters that can be applied to determine the nutritional status of children and adolescents from different countries. Growth graphs are essential to assess the health of children, but depend greatly of the growth tables used. Although BMI can be practical, it does not distinguish body fat from lean mass. The best interpretation of anthropometry will depend of valid reference values for age range of the study population. BIA is a quick feasible method, but the measurement has some various nationalities.


Resumo O objetivo deste artigo é revisar sistematicamente as evidências sobre as técnicas de avaliação nutricional e parâmetros utilizados para determinar o estado nutricional em crianças e adolescentes. Revisão da literatura com busca nas bases de dados, Medline, Lilacs, SciELO e Embase, além de arquivos pessoais. Identificamos 17 artigos que relatavam dados de diferentes populações, sete estudos abordaram os índices antropométricos, quatro o crescimento e o desenvolvimento de crianças e adolescentes por meio de curvas de crescimento, e o restante a composição corporal. Todos preencheram os critérios de qualidade, com exceção das limitações. A revisão da literatura sugere diversas técnicas e parâmetros que podem ser aplicados para determinar o estado nutricional de crianças e adolescentes de diferentes países. Gráficos de crescimento são essenciais para avaliar a saúde de crianças, mas depende muito das tabelas de crescimento utilizadas. Embora o IMC seja prático, não distingue a gordura corporal de massa magra. Existem várias técnicas para avaliar proporções, tamanho e composição corporal. A melhor interpretação da antropometria dependerá de valores de referência válidos para a faixa etária da população estudada. BIA é um método factível, mas tem algumas limitações para a realização do exame.

RESUMO

OBJECTIVE: To describe the frequency of popular myths about and features of asthma treatment in children and adolescents in an urban area in southern Brazil. METHODS: The parents or legal guardians of public school students (8-16 years of age) completed a specific questionnaire regarding their understanding of asthma, asthma control, and treatment characteristics. The sample included parents or legal guardians of students with asthma (n = 127) and healthy controls (n = 124). RESULTS: The study involved 251 parents or legal guardians, of whom 127 (68.5%) were the mothers and 130 (51.8%) were White. The mean age of these participants was 38.47 ± 12.07 years. Of the participants in the asthma and control groups, 37 (29.1%) and 26 (21.0%), respectively, reported being afraid of using asthma medications, whereas 61 (48%) and 56 (45.2%), respectively, believed that using a metered dose inhaler can lead to drug dependence. However, only 17 (13.4%) and 17 (13.7%) of the participants in the asthma and control groups, respectively, reported being afraid of using oral corticosteroids. In the asthma group, 55 students (43.3%) were diagnosed with uncontrolled asthma, only 41 (32.3%) had a prescription or written treatment plan, and 38 (29.9%) used asthma medications regularly. CONCLUSIONS: Popular myths about asthma treatment were common in our sample, as were uncontrolled asthma and inappropriate asthma management. Further studies in this field should be conducted in other developing countries, as should evaluations of pediatric asthma treatment programs in public health systems.

Objetivo: Descrever a frequência de mitos populares e as características do tratamento em asma em crianças e adolescentes em uma amostra urbana no sul do Brasil. Métodos: Foi aplicado um questionário específico, contendo perguntas sobre entendimento da doença, controle da asma e características do tratamento a pais/responsáveis de escolares da rede pública (8-16 anos de idade) com diagnóstico de asma (n = 127) e de controles saudáveis (n = 124). Resultados: Participaram do estudo 251 pais/responsáveis, com predomínio de mães como acompanhantes dos escolares (n = 127; 68,5%) e de etnia caucasiana (n = 130; 51,8%), com média de idade de 38,47 ± 12,07 anos. Sobre os mitos, 37 (29,1%) dos participantes do grupo asma e 26 (21,0%) dos do grupo controle relataram possuir receio de utilizar medicamentos para asma, e 61 (48%) e 56 (45,2%), respectivamente, acreditam que os inaladores pressurizados podem levar a dependência ao fármaco. No entanto, apenas 17 (13,4%) dos participantes do grupo asma e 17 (13,7%) dos do grupo controle relataram ter receio de utilizar corticoide oral. A ausência de controle da asma foi detectada em 55 (43,3%) dos escolares no grupo asma, apenas 41 (32,3%) possuíam uma receita ou um plano por escrito de como tratar da asma e 38 (29,9%) fazia uso contínuo de medicamentos para a doença. Conclusões: A presença de mitos populares sobre o tratamento da asma, a falta de controle da doença e seu manejo inadequado mostraram ser elevados nesta amostra. Nossos achados apontam para a necessidade de novos estudos nesse campo em países em desenvolvimento e de uma avaliação dos programas de manejo da asma pediátrica na saúde pública.

RESUMO

OBJECTIVE: To assess the impact of asthma in a population of inner-city Brazilian children. METHODS: In a cross-sectional study, we selected children with asthma and healthy controls from public schools (8-16 years) from a capital city of Southern Brazil. Divided into three phases, questionnaires were administered, assessing lung function, body mass index and allergic sensitization. RESULTS: From 2500 children initially included in the study (48.4% males; mean age of 11.42 ± 2.32 years), asthma prevalence was detected in 28.6% (715/2500). The disease was not controlled in 42.7% (305/715) of the children, with 7.6% of hospitalization rate. School absenteeism (at least one day of missing school because of asthma) and sedentary behavior were high (57.1 and 67.2%, respectively), with 47.9% of subjects requiring oral steroids in the previous year, and physical well-being significantly lower than controls, directly interfering with quality of life, and therefore in the daily activities of these students. Moreover, 38% of the parents admitted to being non-adherent to treatment with their children and 31.1 and 53.6%, respectively, believed that rescue medication and exercise might be harmful. CONCLUSIONS: The burden of asthma in Brazilian children seems to be substantial. New international guidelines with a special focus in developing countries settings, with more pragmatic approaches, should be a priority for discussion and implementation actions.

RESUMO

The aim of this systematic review is to assess the effects of exercise on telomeres length. We searched the following databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Scopus, LILACS, SPORTDiscus and Web of Science from inception to August 2014. All articles that assessed the effects of exercise in telomere length were included in this review. The search strategy used the following combinations of terms: telomere AND "motor activity" OR exercise OR "physical activity". Two reviewers, working independently, screened all titles and abstracts to identify studies that could meet inclusion criteria. Whenever possible, and if appropriate, we performed a random-effect meta-analysis of study outcomes. Thirty-seven original studies were included in this systematic review, including 41,230 participants. Twenty articles did not find statistically significant association, whereas 15 described a positive association. Two papers found an inverted "U" correlation. There is a tendency toward demonstrating an effect of exercise on telomere length. Few prospective studies were found, many studies did not reach statistical significance and there was an important methodological diversity. For this reason, a possible significant association between physical activity and telomere length remains an open question.
