Declaramos inexistência de conflito de interesses neste artigo RESUMO Objetivo: O objetivo deste estudo foi analisar a prevalência de alterações posturais sagitais na coluna lombar e fatores associados em escolares da Rede Federal de Ensino de Florianópolis. Métodos: Foram avaliados 288 adolescentes (156 do sexo masculino e 132 do feminino), na faixa etária dos 15 aos 18 anos, estudantes da Rede Federal de Ensino de Florianópolis/ SC. Para o levantamento dos dados utilizou-se: fotogrametria seguindo protocolo específico para avaliação postural e questionário para identificar a prevalência de quadros de dor, frequência e atividades que desencadeavam o problema. Na análise de dados utilizou-se de estatística descritiva, teste t de Student para amostras independentes, Qui-quadrado e regressão de Poisson, adotando a significância de 0,05 em todos os testes. Resultados: A prevalência de dor lombar foi de 49,3%, apresentando uma frequência semanal em 43,1% dos avaliados. A prevalência de desvios foi de 53,8%, sendo que 90,9% corresponderam à retificação da curvatura lombar, acometendo mais o sexo masculino. Foi encontrada diferença significativa no ângulo lombar entre os sexos, sendo que o grupo masculino apresentou razões de prevalência superiores de desvios posturais. A variável dor lombar não apresentou associação com desvios posturais sagitais. Conclusão: As prevalências de dor e desvios posturais na coluna lombar foram elevadas, sendo que a relação entre essas variáveis não se apresentou de forma significativa. As principais causas de dor lombar foram a prática de esportes ou atividades vigorosas e a permanência durante longos períodos de tempo na posição sentada. ABSTRACTObjective: The purpose of this study was to assess the prevalence of sagittal lumbar spine changes and associated factors in students of the federal educational system of Florianópolis. Methods: 288 adolescents (156 males and 132 females), aged from 15 to 18 years, students of the Florianópolis' federal school took part in this study. Photometry was used following a specific protocol for postural assessment, and a questionnaire was used to identify the prevalence and frequency of low back pain, and activities that triggered the problem. Descriptive statistics, Student's t-test for independent samples, chi-square test and Poisson's regression were used, with the level of significance set at p<0.05. Results: The prevalence of low back pain was 49.3%, with weekly frequency in 43.1% of the sample. The prevalence of deviation was of 53.8%, and 90.9% corresponded to the rectification of the lumbar curve, affecting more males. Significant differences in lumbar angle between the sexes were found; higher prevalence ratios of lumbar postural deviations was found in the male group. Conclusions: The prevalences of low back pain and lumbar postural changes in adolescents were high, and no significant relationship between those variables was found. Practicing sports or vigorous activities and remaining in a seated position for extended periods of time were the...

ObjectiveTo identify the prevalence of nonspecific lumbar pain and associated factors among adolescents in Uruguaiana, state of Rio Grande do Sul.MethodsThis was a cross-sectional school-based study conducted among adolescents aged 10–17 years who were enrolled in the day shift of the municipal and state educational systems of Uruguaiana. This study evaluated 1455 adolescents. The data-gathering procedures involved two stages. Firstly, a questionnaire on sociodemographic indicators, behavioral patterns and habits of the daily routine and history of nonspecific lumbar pain was applied. Subsequently, height, body mass, flexibility and abdominal strength/resistance measurements were evaluated. To analyze the data, univariate, bivariate and multivariable methods were used and the significance level was taken to be 5% for all the tests.ResultsThe prevalence of lumbar pain among the adolescents evaluated was 16.1%. Grouped according to sex, the prevalence among males was 10.5% and among females, 21.6%. The variables of sex, body mass index, abdominal strength/resistance and physical activity level presented statistically significant associations with nonspecific lumbar pain. In the adjusted analysis, sex (OR = 2.36; p < 0.001), age (OR = 1.14; p < 0.001) and body mass index (OR = 1.44; p = 0.029) maintained significance in the final model.ConclusionsFemale adolescents of older age and who presented overweight or obesity had higher chances of developing nonspecific lumbar pain.

Objectives: to identify the prevalence of high arterial blood pressure (ABP) , respectively. The factors that remained associated with high systolic and diastolic ABP in the final model were: perceiving oneself to be less fit than one's peers (systolic OR: 2.27; diastolic OR: 2.99;) and overweight and obesity (systolic OR: 9.29; diastolic OR: 4.70; 16,4% (IC95%: 14,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]4) e de 18,5% (IC95%: 16,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]6), respectivamente. Permaneceram associados à PA sistólica e diastólica elevadas no modelo final: se perceber menos em forma que seus pares (sistólica OR: 2,27; IC95%: 1,23; diastólica OR: 2,99; IC95%: 1,70) e o sobrepeso e obesidade (sistólica OR: 9,29; IC95%: 4,69; diastólica OR: 4,70; IC95%: 2,45
