Este estudo teve como objetivo verificar a prevalência de sobrepeso, obesidade e o nível de atividade física segundo o sexo de crianças e adolescentes de escolas públicas da cidade de Nantes, São Paulo, Brasil. A amostra foi composta de 170 crianças e 232 adolescentes com a idade média de 8,04±1,31 e 13,2±1,83 anos, respectivamente, de ambos os sexos e frequentadores de duas escolas. Foram coletadas as medidas antropométricas: Índice de massa corpórea pela idade (IMC/idade) e circunferência abdominal. O IMC/idade foi classificado de acordo com o Sistema de Vigilância Alimentar e Nutricional (SISVAN) (2007) e um questionário modificado e adaptado sugerido por Silva (2009) foi utilizado para analisar o nível de atividade física. O teste t não pareado foi realizado e os valores de p<0,05 foram considerados significativos.A prevalência de 30,59% dos indivíduos com sobrepeso ou obesidade, foi verificada sendo a maioria desta adolescente. Também foi encontrada maior média e com diferença significativa do valor da circunferência abdominal no sexo feminino no grupo das crianças. Foi observado que 62,68% da amostra são inativos ou inadequadamente ativos e que a maioria desses era do sexo feminino. Estes fatos demonstram considerável risco que estes indivíduos podem apresentar de complicações cardiovasculares e musculoesqueléticas no decorrer da vida. A importância da realização precoce de programas educacionais e nutricionais na escola deve ser enfatizada para prevenção e tratamento destes indivíduos com excesso de peso e baixo nível de atividade física.

This study sought to evaluate motor development in children aged 6 to 11 years with learning difficulties and school characteristics of delayed motor development, before and after application of a motor intervention program. The sample consisted of 28 children with a mean age of 107.21 ± 16.56 months, who were evaluated by the Motor Development Scale and received motor intervention for 6 months, followed by reassessment. We observed a statistically significant difference between the average of the motor activity ratios in all areas of the evaluation and reevaluation. Also verified in the evaluation were the concentration ratios of children with motor activity greater than or equal to 80 and there was a revaluation increase in this concentration on re-evaluation, the areas with the greatest increase in concentration and significant differences being: Body Schema, Space and temporal Organization. In the overall evaluation of MDS, most children presented the classification of "low normal". However, in the reassessment most have evolved into the "average normal", only 4 of themremaining in the same classification. Therefore, in this study, children with learning disabilities also showed motor deficits and the intervention applied contributed to an increase in the motor ratios with consequent improvement in motor development. Besides psychopedagogical asistance, it is essential to reassess them and if necessary apply the intervention in the motor development of children with learning difficulties.

BackgroundIndividuals with Cerebral Palsy (CP) present with sensorimotor dysfunction which make the control and execution of movements difficult. This study aimed to verify the speed-accuracy trade-off in individuals with CP.MethodsForty eight individuals with CP and 48 with typical development (TD) were evaluated (32 females and 64 males with a mean age of 15.02 ± 6.37 years: minimum 7 and maximum 30 years). Participants performed the “Fitts’ Reciprocal Aiming Task v.1.0 (Horizontal)” on a computer with different sizes and distance targets, composed by progressive indices of difficulty (IDs): ID2, ID4a and ID4b.ResultsThere were no statistical differences between the groups in relation to the slope of the curve (b1) and dispersion of the movement time (r2). However, the intercept (b0) values presented significant differences (F(1.95) = 11.3; p = .001]), with greater movement time in the CP group compared to the TD group. It means that for individuals with CP, regardless of index difficulty, found the task more difficult than for TD participants. Considering CP and TD groups, speed-accuracy trade-off was found when using different indices of difficulty (ID2 and ID4). However, when the same index of difficulty was used with a larger target and longer distance (ID4a) or with a narrow target and shorter distance (ID4b), only individuals with CP had more difficulty performing the tasks involving smaller targets. Marginally significant inverse correlations were identified between the values of b1 and age (r = −0.119, p = .052) and between r2 and Gross Motor Function Classification System (r = −0.280, p = .054), which did not occur with the Manual Ability Classification System.ConclusionWe conclude that the individuals with CP presented greater difficulty when the target was smaller and demanded more accuracy, and less difficulty when the task demanded speed. It is suggested that treatments should target tasks with accuracy demands, that could help in daily life tasks, since it is an element that is generally not considered by professionals during therapy.Trial registrationClinicalTrials.gov, NCT03002285, retrospectively registered on 20 Dec 2016.
