          Abstract

          O Teste de Coordenação Corporal para Crianças (Körperkoordinationstest für Kinder, KTK) tem sido utilizado na avaliação da coordenação motora de crianças e adolescentes. O objetivo desta revisão sistemática com meta-análise foi analisar a relação entre o índice de massa corporal (IMC) e o desempenho motor no KTK em crianças e jovens escolares saudáveis. O estudo baseou-se em pesquisas indexadas nas bases eletrônicas PubMed e SciELO. Os descritores foram: "Körperkoordinationstest für Kinder" e "KTK". Foram considerados artigos em inglês e português publicados até Outubro de 2014. A qualidade dos estudos foi determinada pelas Escalas PEDro e STROBE. Foi realizada meta-análise utilizando o software Comprehensive Meta-Analysis V2. Foram incluídos 10 estudos. O resultado global com base no modelo de efeitos fixos mostrou que valores maiores de IMC estão diretamente associados ao baixo desempenho no KTK. Apesar da pequena diferença entre ambos, a magnitude do efeito da associação foi classificada como pequena, porém, significativa para o sexo masculino (r=0,29; IC95% 0,27 a 0,32; Z=22,47; p=0,000) e moderada para o sexo feminino (r=0,32; IC95% 0,30 a 0,34; Z=24,76; p=0,000). Os estudos apresentaram características amostrais bastante divergentes quanto ao tamanho da amostra e a faixa etária dos sujeitos, além de nenhum deles ter analisado o estado maturacional dos participantes. Conclui-se que há uma tendência de relação positiva entre valores elevados de IMC e o baixo desempenho no KTK. Para confirmação desta tendência, recomenda-se que os próximos trabalhos considerem o estado maturacional dos participantes, além de possibilitarem uma análise por sexo e idade.

          The Body Coordination Test for Children (Körperkoordinationstest für Kinder, KTK) has been used in the evaluation of motor coordination in young people. The objective of this systematic review and meta-analysis study was to analyze the relationship between body mass index (BMI) and the motor performance by the KTK test in healthy children. The study was based on research indexed in the electronic databases PubMed and SciELO. The descriptors were "Körperkoordinationstest für Kinder" and "KTK". Studies published in English and Portuguese until October 2014 were considered. The quality of the studies was determined by PEDro and STROBE scales. Meta-analysis was performed using the Comprehensive Meta-Analysis V2 software. A total of 10 studies were included. The overall result based on the fixed effects model showed that higher values of the BMI are directly associated with low performance in the KTK. Despite the small difference between genders, the magnitude of the association effect was classified as small, but significant for males (r = 0.29; 95% CI 0.27 to 0.32; Z = 22.47; p = 0.000) and moderate for females (r = 0.32; 95% CI 0.30 to 0.34; Z = 24.76, p = 0.000). Studies have shown different characteristics as the sample size and the age of the subjects, and none of them have analyzed the maturational status of the participants. Based on these results, there is a trend of a positive relationship between high values of BMI and low performance in the KTK.

          The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement: guidelines for reporting observational studies.

          Much of biomedical research is observational. The reporting of such research is often inadequate, which hampers the assessment of its strengths and weaknesses and of a study's generalizability. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Initiative developed recommendations on what should be included in an accurate and complete report of an observational study. We defined the scope of the recommendations to cover three main study designs: cohort, case-control, and cross-sectional studies. We convened a 2-day workshop in September 2004, with methodologists, researchers, and journal editors to draft a checklist of items. This list was subsequently revised during several meetings of the coordinating group and in e-mail discussions with the larger group of STROBE contributors, taking into account empirical evidence and methodological considerations. The workshop and the subsequent iterative process of consultation and revision resulted in a checklist of 22 items (the STROBE Statement) that relate to the title, abstract, introduction, methods, results, and discussion sections of articles. Eighteen items are common to all three study designs and four are specific for cohort, case-control, or cross-sectional studies. A detailed Explanation and Elaboration document is published separately and is freely available on the web sites of PLoS Medicine, Annals of Internal Medicine, and Epidemiology. We hope that the STROBE Statement will contribute to improving the quality of reporting of observational studies.

            Physical activity guidelines for children and adolescents: a critical review.

            J. Twisk (2000)
            Since it is generally accepted that the onset of many chronic diseases lies in early childhood, preventive strategies should start as early in life as possible. Physical inactivity is recognised as an important determinant for chronic disease and the prevalence of physical inactivity is increasing during adolescence. Therefore, in the last 10 years much effort has been put into the development of physical activity guidelines for children and adolescents. In this critical review it is shown that the scientific evidence on which these guidelines are based is rather weak. There is only marginal evidence that physical activity during youth is related to adult health status. There is, however, hardly any evidence for a certain dose-response relationship or a particular threshold value from which guidelines can be obtained. Furthermore, it can be suggested that although the value of physical activity guidelines for children and adolescents for public health purposes is beyond doubt, perhaps these guidelines should focus on aspects other than possible health benefits.

              Motor coordination difficulties and physical fitness of extremely-low-birthweight children.

              Motor coordination difficulties and poor fitness exist in the extremely low birthweight (ELBW) population. This study investigated the relative impact of motor coordination on the fitness of ELBW children aged 11 to 13 years. One hundred and nine children were recruited to the study: 54 ELBW participants (mean age at assessment 12y 6mo; 31 male, 23 female; mean birthweight 769g, SD 148g; mean gestational age 26.6 weeks, SD 2.1 weeks) and 55 comparison children (mean age at assessment 12y 5mo; 28 males, 27 females; at least 37 weeks' gestation). All children completed the Movement Assessment Battery for Children (MABC), functional tests of postural stability and strength, growth measures, and tests of respiratory function. Maximal oxygen uptake (VO(2)max) was calculated from a 20m shuttle run test as a measure of fitness. The ELBW group had greater problems with postural stability (p=0.001) and motor coordination (p=0.001), with 70% rated as having a definite motor problem on the MABC brackets (those who scored less than the 5(th) centile on the MABC). The ELBW was also less fit than the comparison group (p=0.001), with 45% below the 10th centile for VO(2)max. There were differences between the groups for growth, strength, and particularly respiratory function. However, respiratory function did not significantly correlate with VO(2)max in the ELBW group. Motor coordination was the most powerful predictor of VO(2)max in both the ELBW (p=0.001) and the comparison groups (p=0.001).
