心脏代谢危险因素的聚集可发生在儿童时期，使个体易患心脏代谢疾病。这项研究计算了100名10-14岁儿童和青少年（59名女孩）的心脏代谢风险，并根据心肺适能（CRF）水平和不同体力活动（PA）强度的时间探索了差异。CRF采用最大踏车测力计试验确定，PA采用加速度计评估。心血管代谢风险评分计算为腰围、血压、总胆固醇/高密度脂蛋白比值、甘油三酯和葡萄糖的标准化评分之和。根据先前提出的健康相关阈值，使用ANCOVA评估了健康和不健康参与者之间的聚集性心脏代谢风险差异，以及PA子成分三分位数之间的差异。健康组（平均1.21 +/- 3.42）与不健康组（平均-0.74 +/- 2.22）相比，患病风险显著较低（p < 0.001），而PA的任何子组分的三分位数之间不存在差异。结论CRF可能对儿童和青少年具有重要的心脏保护作用，并强调了在青少年中推广CRF的重要性。
Clustering of cardiometabolic risk factors can occur during childhood and predisposes individuals to cardiometabolic disease. This study calculated clustered cardiometabolic risk in 100 children and adolescents aged 10-14 years (59 girls) and explored differences according to cardiorespiratory fitness (CRF) levels and time spent at different physical activity (PA) intensities. CRF was determined using a maximal cycle ergometer test, and PA was assessed using accelerometry. A cardiometabolic risk score was computed as the sum of the standardised scores for waist circumference, blood pressure, total cholesterol/high-density lipoprotein ratio, triglycerides and glucose. Differences in clustered cardiometabolic risk between fit and unfit participants, according to previously proposed health-related threshold values, and between tertiles for PA subcomponents were assessed using ANCOVA. Clustered risk was significantly lower (p < 0.001) in the fit group (mean 1.21 +/- 3.42) compared to the unfit group (mean -0.74 +/- 2.22), while no differences existed between tertiles for any subcomponent of PA. Conclusion These findings suggest that CRF may have an important cardioprotective role in children and adolescents and highlights the importance of promoting CRF in youth.
