Objectives: The objectives of this study were to determine the prevalence of and factors associated with poor self-rated health among elementary school teachers and to investigate whether poor self-rated health can predict absenteeism, presenteeism, and sick leave.
Methods: The sample comprised 493 elementary school teachers from Londrina, Paraná, Brazil.
Purpose: the aim of this study was to analyze the association between upper limb muscular fitness and spinal pain in the cervical, thoracic, and lumbar regions among young people.

Methods:: The study enrolled 738 adolescents of Londrina city, Paraná, Southern Brazil. The following variables were collected by a self report questionnaire: presence of moderate to vigorous physical activity, gender, age, father and mother education level, with whom the adolescent lives, number of siblings, physical activity perception, participation in Physical Education classes, facilities available to physical activity practice and sedentary behavior.
Purpose: To evaluate the accuracy of the body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) in detecting excess body fat among schoolchildren in Florianópolis, Santa Catarina.
Methods: Cross-sectional study with 2,772 schoolchildren aged seven to ten years. Receiver Operating Characteristic (ROC) curves were used to compare the diagnostic accuracy of the BMI, the WC and the WHtR in identifying children with excess body fat (defined as values that were equal to or higher than the 90th percentile of the standardized residuals obtained from the sum of the four skinfolds thickness).
