We aimed to analyze the cross-sectional and longitudinal association of physical activity (PA) levels and PA patterns with metabolic syndrome score (MetS) in children and adolescents.
A total of 175 children (82 females) and 188 adolescents (95 females) were included. Objective PA levels and patterns were determined by accelerometry. MetS was computed from waist circumference, systolic blood pressure, triglycerides, high-density lipoprotein cholesterol, and glucose levels. Different linear regression models were implemented to examine the associations of PA with MetS.
Vigorous PA, moderate-vigorous PA, number of bouts per day in 10 min (N10), and total time in bouts per day in 10 min (T10) were negatively associated with MetS in male children and adolescents at cross-sectional level (β ranging from -0.005 to -0.164, all p < 0.05). Total time in bouts per day in 20 min in male children, and vigorous PA and N10 in female children were longitudinally and negatively associated with MetS (β ranging from -0.011 to -0.247, all p < 0.05).
Associations of PA and MetS were observed at cross-sectional level in males and longitudinally in female children. The associations in PA patterns were found when patterns were grouped into bouts of 10 min. Therefore, for future studies of PA with health markers in the pediatric population, it would be advisable to choose bouts of shorter duration.
我们旨在分析儿童和青少年的身体活动（PA）水平及PA模式与代谢综合征评分（MetS）之间的横断面和纵向关联。
共纳入175名儿童（82名女性）和188名青少年（95名女性）。通过加速度计测定客观的PA水平和模式。根据腰围、收缩压、甘油三酯、高密度脂蛋白胆固醇和血糖水平计算MetS。采用不同的线性回归模型来检验PA与MetS之间的关联。
在横断面水平上，男性儿童和青少年的剧烈PA、中等强度-剧烈PA、每天10分钟的发作次数（N10）以及每天10分钟发作的总时长（T10）与MetS呈负相关（β范围为-0.005至-0.164，均p<0.05）。男性儿童每天20分钟发作的总时长、女性儿童的剧烈PA和N10与MetS呈纵向负相关（β范围为-0.011至-0.247，均p<0.05）。
在男性中观察到PA与MetS的横断面关联，在女性儿童中观察到纵向关联。当将PA模式分组为10分钟的发作时，发现了PA模式与MetS之间的关联。因此，对于未来在儿科人群中研究PA与健康指标的研究，建议选择较短时长的发作。
