Nutritional status of children and adolescents based on body mass index: agreement between World Health Organization and International Obesity Task Force.

Objective: To investigate the agreement between two international criteria for classification of children and adolescents nutritional status. Methods: The study included 778 girls and 863 boys aged from six to 13 years old. Body mass and height were measured and used to calculate the body mass index. Nutritional status was classified according to the cut-off points defined by the World Health Organization and the International Obesity Task Force. The agreement was evaluated using Kappa statistic and weighted Kappa. Results: In order to classify the nutritional status, the agreement between the criteria was higher for the boys (Kappa 0.77) compared to girls (Kappa 0.61). The weighted Kappa was also higher for boys (0.85) in comparison to girls (0.77). Kappa index varied according to age. When the nutritional status was classified in only two categories - appropriate (thinness + accentuated thinness + eutrophy) and overweight (overweight + obesity + severe obesity) -, the Kappa index presented higher values than those related to the classification in six categories. Conclusions: A substantial agreement was observed between the criteria, being higher in males and varying according to the age.Objective: To investigate the agreement between two international criteria for classification of children and ado - lescents nutritional status.

Comparação da aptidão física relacionada à saúde e a prática esportiva em crianças

This study aimed to compare the level of physical fitness related to health and the sports practice in children. A total of 468 children (8 to 10 years) were evaluated. The physical fitness tests followed PROESP-BR standards; Anthropometric measurements of body mass and height were performed to determine body mass index (BMI). Student’s t-test was applied in the comparative between the genders and the chi-square test to determine differentiation in the percentage of classification, with significance level established in (p<0.05). There were significant differences in body mass, BMI, abdominal resistance, lower limb strength, upper limb strength and cardiorespiratory fitness, with boys presented better results than girls, only in flexibility girls overcome boys. The chi-square test did not present differences in the obtained classifications. Boys presented better results when compared to girls at physical fitness, as much related to the health as the sport practice.

A INFÂNCIA, O BRINCAR E O JOGAR: REFLEXÕES A PARTIR DO REFERENCIAL TEÓRICO DE NORBERT ELIAS

A fase em que se estabelece a infância e um periodo essencial na vida dos seres humanos, nao so para o desenvolvimento fisico e cognitivo, mas tambem para o desenvolvimento social, cujo qual e um aspecto de suma importância frente a convivencia em sociedade. Contudo, apesar do reconhecimento desta importante etapa do desenvolvimento humano, estudos sob o ponto de vista sociologico tem sido pouco explorados na literatura. Partindo deste cenario e sabendo entao da incipiente investigacao sobre o tema na esteira das ciencias sociais, o presente texto tem como desiderato contextualizar o papel da infância e de suas atividades, tais como o brincar e o jogar, no contexto do processo civilizador e tambem partir de outros referenciais teoricos do sociologo alemao Norbert Elias.

Associação entre (in) satisfação com a imagem corporal, estado nutricional e nível de coordenação motora em crianças e adolescentes de projetos esportivos

Objetivo: identificar o nivel de (in) satisfacao corporal, estado nutricional e coordenacao motora de criancas e adolescentes participantes de projetos esportivos e suas possiveis associacoes. Metodo: a amostra foi composta por 84 participantes de projetos esportivos com faixa etaria entre nove a 16 anos, de ambos os sexos. A coordenacao motora foi avaliada pelo teste KTK (Korperkoordinationstest Fur Kinder), o estado nutricional atraves do indice de massa corporal (IMC) e a imagem corporal pelas silhuetas. Para a analise estatistica, foram utilizados media e desvio padrao, teste T, frequencia absoluta e relativa e o teste qui-quadrado. Resultados: identificou-se que 21,4% apresentam sobrepeso; na classificacao do desempenho da coordenacao motora, 27,4% apresentam perturbacoes na coordenacao e 13,1% insuficiencia na coordenacao; ja em relacao a imagem corporal, 63,1% apresentam insatisfacao com sua silhueta. Consideracoes finais: a coordenacao motora nao esteve associada com o IMC; por outro lado, a insatisfacao corporal apresentou relacao com o estado nutricional, sendo que os escolares apresentam uma imagem corporal distorcida, uma vez que a maior parte daqueles que apresentam excesso de peso estao insatisfeitos com seu corpo pela magreza.
