- Health-related physical fitness is associated with selected sociodemographic and behavioral factors in brazilian school childrenPublication . Guedes, Dartagnam Pinto; Neto, Jaime Tolentino Miranda; Lopes, Vitor P.; Silva, A.J.This study investigated the association between sociodemographic and behavioral factors and health standards based on physical fitness component scores in a sample of Brazilian schoolchildren. Methods: A sample of 1457 girls and 1392 boys aged 6 to 18 years performed a test battery of 5 items: 1) sit-and-reach, 2) curl-up, 3) trunk-lift, 4) push-up, and 5) progressive endurance run (PACER). The cut-off scores for gender and age suggested by the FitnessGram were adopted. Results: The findings showed that the sociodemographic and behavioral factors significantly associated with the ability of schoolchildren of meeting the health standards varied according to the fitness test. In the 5 tests used girls presented lower chance of meeting the health standards. Age and socioeconomic class were negatively associated with the performance in all physical tests. Schoolchildren aged ≤ 9 years or from families of lowest socioeconomic class presented approximately twice the chance of meeting the health standards than those aged ≥ 15 years and from more privileged families, specifically in the push-up (OR = 2.40; 95% CI 2.01–2.82) and PACER (OR = 2.18; 95% CI 1.84–2.54) tests. Conclusions: Interventions to promote health-related physical fitness should not only consider gender and age of schoolchildren, but also selected sociodemographic and behavioral factors, especially socioeconomic class and leisure activities.
- Physical growth of schoolchildren from the Jequitinhonha Valley, Minas Gerais, Brazil: Comparison with the CDC-2000 reference using the LMS methodPublication . Guedes, Dartagnam Pinto; Matos, José Arlen Beltrão; Lopes, Vitor P.; Ferreirinha, José Eduardo; Silva, A.J.Objective: To analyse the physical growth of a representative school population sample from the Jequitinhonha Valley, Minas Gerais, Brazil, in comparison with the reference proposed by the Centre for Disease Control and Prevention (CDC-2000). Methods: The sample was composed of 5100 individuals (2730 girls and 2370 boys), aged 6-18 years. Body weight-for-age and height-for-age percentiles were obtained using the LMS method. Statistical and graphical comparisons were made with the corresponding percentiles of the CDC-2000 reference, estimated using the same method. Results: Overall, the calculated values of the L (asymmetry) and the S (variability) parameters were quite similar to the CDC-2000 reference values. However, M(median) was substantially different from the reference used in the study, mainly in schoolchildren over 12-13 years of age of both genders. The magnitude of the deficits of height-for-age and body weight-for-age observed in the schoolchildren from the Jequitinhonha Valley, Minas Gerais, Brazil, varied from 4 to 6 cm and from 3 to 6 kg, respectively. Conclusion: The body weight-for-age and height-for-age percentiles of schoolchildren population in the Jequitinhonha Valley, Minas Gerais, Brazil differed substantially from those referenced.
