ABSTRACT
Abstract Low back pain is increasing considerably among adolescents, reaching proportions similar to the adult population. Flexibility (Flex) and muscle strength/resistance, components of Health-Related Physical Fitness (HRPF), seem to be associated with presence of low back pain. The aim of this study was to assess the ability of Flex and muscle strength/resistance in the screening of adolescents with low back pain and to propose cutoff points for these HRPF components. The study was conducted with 1.455 students aged 10-17 years randomly selected. Low back pain was estimated using a questionnaire. Flex was measured by the sit and reach test and muscle strength/resistance by the one minute sit up test. The analysis of the receiver operating characteristic (ROC) curve was used to identify the capacity of Flex and muscle strength/resistance for screening low back pain. To propose cutoffs points, the best balance between sensitivity and specificity was analyzed. The frequency of low back pain was 16.1 %, higher (p<0.05) among females (21.6%) than in males (10.5%). The ROC curve analysis indicated that Flex is able to identify girls more likely of having low back pain (p<0.05). Sit and reach test and the proposed cutoff points can be used as screening tool of female adolescents more likely of having low back pain.
RESUMO
Resumo A dor lombar vem aumentando consideravelmente entre os adolescentes, atingindo proporções semelhantes à da população adulta. A flexibilidade (Flex) e a força/resistência muscular (F/R), componentes da Aptidão Física Relacionada à Saúde (ApFRS), parecem estar associadas à presença de dor lombar. O objetivo do estudo foi verificar a capacidade da Flex e da F/R na triagem de adolescentes com dor lombar e propor pontos de corte para estes componentes da ApFRS. O estudo foi realizado com 1.455 escolares de 10 a 17 anos selecionados aleatoriamente. A dor lombar foi estimada através de questionário. A Flex foi medida através do teste de sentar e alcançar e a F/R pelo teste de abdominais em 1 minuto. A análise da curva Receiver Operating Characteristic (ROC) foi utilizada para a identificação da capacidade da Flex e da F/R para a triagem de dor lombar. Para a proposição dos pontos de corte, foi analisado o melhor ajustamento entre sensibilidade e especificidade. A frequência de dor lombar foi de 16,1%, sendo maior (p<0,05) entre o sexo feminino (21,6%) do que no masculino (10,5%). A análise da curva ROC indicou que a Flex é capaz de identificar meninas com probabilidade aumentada de apresentarem dor lombar (p<0,05). O teste de sentar e alcançar e os pontos de corte propostos podem ser utilizados como instrumento de triagem de adolescentes do sexo feminino com probabilidade aumentada de apresentarem dor lombar.
