Abstract

Purpose: To investigate the associations between physical activity (PA) intensities, sedentary behavior (SB), and blood pressure (BP) in adolescents, according to sex.

Method: This cross-sectional study involved 95 male and female adolescents aged 15-18 years. Accelerometry was used to measure time spent in light-intensity PA (LPA), moderate to vigorous PA (MVPA), and vigorous PA, and SB. The BP was determined using an automated sphygmomanometer. Statistical analyses included multiple linear regression and command margins.

Results: Significant associations were found between systolic BP (SBP) and time spent in LPA (B = -0.08; 95% CI, -0.15 to -0.01) and SB (B = 0.071; 95% CI, 0.004-0.138), albeit only in boys. Furthermore, an interaction was observed between time spent in SB and MVPA for SBP in boys (B = -0.002; 95% CI, -0.004 to -0.0008). The main interaction effect of increasing SBP was a combination of <75 minutes per day of MVPA and up to 600 minutes per day of SB.

Conclusions: Increased time in LPA and reduced time spent in SB during the day are associated with lower SBP in male adolescents. Additionally, the relation between SB and SBP was attenuated by MVPA. These findings provide crucial insights for PA recommendations to promote cardiovascular health in adolescents.

轻强度体育活动和久坐行为与青少年的血压水平有关。

目的：研究不同性别青少年的体力活动（PA）强度、久坐行为（SB）和血压（BP）之间的关系：这项横断面研究涉及 95 名 15-18 岁的男女青少年。研究使用加速度计测量轻度运动强度（LPA）、中度至剧烈运动强度（MVPA）、剧烈运动强度和 SB 所花费的时间。使用自动血压计测量血压。统计分析包括多元线性回归和指令差：结果发现，收缩压（SBP）与 LPA（B = -0.08；95% CI，-0.15 至 -0.01）和 SB（B = 0.071；95% CI，0.004 至 0.138）所花费的时间之间存在显著关联，尽管这只针对男孩。此外，在男孩中，SB 和 MVPA 所花费的时间与 SBP 之间存在交互作用（B = -0.002；95% CI，-0.004 至 -0.0008）。增加 SBP 的主要交互效应是综合结论：在一天中，LPA时间的增加和SB时间的减少与男性青少年SBP的降低有关。此外，SB 和 SBP 之间的关系因 MVPA 而减弱。这些发现为促进青少年心血管健康的 PA 建议提供了重要启示。

期刊介绍： Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach. Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
