Low physical activity (PA) is a major risk factor for cardiovascular and metabolic disorders in all age groups. We measured intensity and volume of PA and examined the associations between PA and the metabolic syndrome (MS), its components and body composition among young Finnish adults.
The study comprises 991 men and women born 1985-86, who participated in a clinical study during the years 2009-11 which included assessments of metabolism, body composition and PA. Objectively measured (SenseWear Armband) five-day PA data was available from 737 participants and was expressed in metabolic equivalents of task (MET).
The prevalence of MS ranged between 8-10%. Higher total mean volume (MET-hours) or intensity (MET) were negatively associated with the risk of MS and separate components of MS, while the time spent at sedentary level of PA was positively associated with MS.
MS was prevalent in approximately every tenth of the young adults at the age of 24 years. Higher total mean intensity and volume rates as well as longer duration spent at moderate and vigorous PA level had a beneficial impact on the risk of MS. Longer time spent at the sedentary level of PA increased the risk of MS.
低体力活动（PA）是所有年龄组心血管和代谢紊乱的主要危险因素。我们测量了PA的强度和量，并研究了芬兰年轻成年人中PA与代谢综合征（MS）、其组成成分及身体成分之间的关联。
该研究纳入了991名1985 - 1986年出生的男性和女性，他们在2009 - 2011年期间参与了一项临床研究，其中包括对代谢、身体成分和PA的评估。737名参与者有通过客观测量（SenseWear臂带）获得的为期五天的PA数据，数据以代谢当量（MET）表示。
MS的患病率在8% - 10%之间。较高的总平均量（MET - 小时）或强度（MET）与MS风险及其单独组分呈负相关，而处于久坐PA水平的时间与MS呈正相关。
在24岁的年轻成年人中，大约每十分之一的人患有MS。较高的总平均强度和量率以及在中等强度和高强度PA水平下花费更长时间对MS风险有有益影响。在久坐PA水平下花费更长时间会增加MS风险。
