摘要
目的考虑到心肺功能(CRF)的中介作用,研究与心脏代谢健康相关的体力活动(PA)强度:方法:调查了瑞典CArdio-Pulmonary bioImage横断面研究中 50-64 岁男性和女性的子样本。加速度测量法测量了PA,亚极限循环测试测量了CRF。包括腰围、收缩压、高密度脂蛋白、甘油三酯和糖化血红蛋白在内的心脏代谢风险因素被合并为一个综合评分。通过偏最小二乘法结构方程模型建立的中介模型,分析了CRF在PA与综合得分之间的关联中的作用:结果:该队列包括 4185 人(51.9% 为女性),平均年龄为 57.2 岁。82%的CRF介导了PA与综合评分之间的关系。PA 模式分析显示,中等强度的 PA 可解释综合评分的大部分变化,而剧烈强度的 PA 则可解释 CRF 的大部分变化。当把 PA 和 CRF 都作为综合评分的预测因素时,剧烈强度的重要性增加了:结论:CRF 在 PA 与心脏代谢健康之间的关联中发挥着高度相互关联的作用,这表明除了对 CRF 的影响外,PA 对心脏代谢健康的直接影响有限。研究结果强调了足够强度的 PA 与 CRF 之间关系的重要性,而 CRF 又与更好的心脏代谢健康相关联。
Fitness-related physical activity intensity explains most of the association between accelerometer data and cardiometabolic health in persons 50-64 years old.
Objectives: To investigate the physical activity (PA) intensity associated with cardiometabolic health when considering the mediating role of cardiorespiratory fitness (CRF).
Methods: A subsample of males and females aged 50-64 years from the cross-sectional Swedish CArdioPulmonary bioImage Study was investigated. PA was measured by accelerometry and CRF by a submaximal cycle test. Cardiometabolic risk factors, including waist circumference, systolic blood pressure, high-density lipoprotein, triglycerides and glycated haemoglobin, were combined to a composite score. A mediation model by partial least squares structural equation modelling was used to analyse the role of CRF in the association between PA and the composite score.
Results: The cohort included 4185 persons (51.9% female) with a mean age of 57.2 years. CRF mediated 82% of the association between PA and the composite score. The analysis of PA patterns revealed that moderate intensity PA explained most of the variation in the composite score, while vigorous intensity PA explained most of the variation in CRF. When including both PA and CRF as predictors of the composite score, the importance of vigorous intensity increased.
Conclusion: The highly interconnected role of CRF in the association between PA and cardiometabolic health suggests limited direct effects of PA on cardiometabolic health beyond its impact on CRF. The findings highlight the importance of sufficient PA intensity for the association with CRF, which in turn is linked to better cardiometabolic health.
