To analyze the association between participation and physical activity during Physical Education classes with health outcomes in Brazilian students.
681 Brazilian students (50.5% female) aged 10 to 17 years participated in this cross-sectional study. Independent variables analyzed were participation and physical activity during Physical Education classes, both assessed using a self-report questionnaire. The outcomes were: cardiorespiratory fitness (20-meter Shuttle Run test), muscle strength (Push-up test), overweight and obesity (body mass index) and high blood pressure. Statistical analysis was conducted by Poisson regression to estimate the prevalence ratio (PR) and 95% confidence intervals (95%CI) adjusted for confounding variables (age, sex, parental education, physical activity and sedentary behavior), considering the complex sample design.
Participation in Physical Education classes was not associated with any of the studied variables. Being active during Physical Education classes was associated with achieving health related criteria for cardiorespiratory fitness (PR=1.34, 95%CI 1.16-1.55) and muscle strength (PR=1.36, 95%CI 1.09-1.71). The same did not occur for overweight (PR=1.04, 95%CI 0.95-1.14), obesity (PR=1.02, 95%CI 0.91-1.05), or high blood pressure (PR=0.98, 95%CI 0.90-1.06).
Students who reported being active during classes presented a higher likelihood to achieve the health criteria for cardiorespiratory fitness and muscle strength. However, classes traditionally offered in Brazil do not protect students from overweight, obesity, or high blood pressure.
分析巴西学生体育课参与度和体育活动与健康结果之间的关联。
681名年龄在10至17岁的巴西学生（50.5%为女性）参与了这项横断面研究。分析的自变量为体育课参与度和体育活动，均通过自填问卷进行评估。结果包括：心肺适能（20米往返跑测试）、肌肉力量（俯卧撑测试）、超重和肥胖（身体质量指数）以及高血压。考虑到复杂样本设计，通过泊松回归进行统计分析，以估计经混杂变量（年龄、性别、父母教育程度、体育活动和久坐行为）调整后的患病率比值（PR）和95%置信区间（95%CI）。
体育课参与度与任何一项研究变量均无关联。体育课上积极活动与达到心肺适能（PR = 1.34，95%CI 1.16 - 1.55）和肌肉力量（PR = 1.36，95%CI 1.09 - 1.71）的健康相关标准有关。超重（PR = 1.04，95%CI 0.95 - 1.14）、肥胖（PR = 1.02，95%CI 0.91 - 1.05）或高血压（PR = 0.98，95%CI 0.90 - 1.06）方面则未出现这种情况。
报告在课堂上积极活动的学生达到心肺适能和肌肉力量健康标准的可能性更高。然而，巴西传统的体育课并不能保护学生免于超重、肥胖或高血压。
