The objective of this study was to establish cut-points to identify potential clustered cardiometabolic risk among children (aged 9-13 years) and youth (aged 14-17 years) using the modified Canadian Aerobic Fitness Test (mCAFT). Nationally representative cross-sectional data were obtained from cycles 1 and 2 (2007-2011) of the Canadian Health Measures Survey. Cardiorespiratory fitness was measured using the mCAFT, which was used to estimate peak oxygen consumption. Clustered cardiometabolic health was identified as the mean of 4 standardized variables: sum of 4 skinfolds; total cholesterol-to-high-density lipoprotein ratio; and systolic and diastolic blood pressure. In total, 2106 (49% female) participants were retained for this analysis. The optimal mCAFT cut-point for males was 49 and 46 mL·kg·min among children and youth, respectively. Among females, the mCAFT cut-point was 46 and 37 mL·kg·min among children and youth, respectively. In 2016-2017, 83% of females and 71% of males met the new mCAFT cut-points. The mCAFT cut-points can help identify children and youth at potential risk of poor cardiometabolic health in public health surveillance, clinical, and school-based settings. We developed new mCAFT cut-points to identify potential clustered cardiometabolic risk among Canadian children and youth. These mCAFT cut-points can be used to inform national health surveillance efforts.
本研究旨在利用改良加拿大有氧健身测试（mCAFT）为儿童（9-13 岁）和青少年（14-17 岁）确定潜在的聚集性心血管代谢风险切点。本研究使用来自加拿大健康衡量调查（Canadian Health Measures Survey）第 1 轮和第 2 轮（2007-2011 年）的全国代表性横断面数据。心肺功能使用 mCAFT 进行测量，该测试用于估计峰值耗氧量。聚集性心血管代谢健康被定义为 4 个标准化变量的平均值：4 个皮褶厚度之和；总胆固醇/高密度脂蛋白比值；收缩压和舒张压。总共有 2106 名（49%为女性）参与者纳入了此项分析。男性的最佳 mCAFT 切点为儿童和青少年分别为 49 和 46mL·kg·min。对于女性，mCAFT 切点分别为儿童和青少年 46 和 37mL·kg·min。在 2016-2017 年，83%的女性和 71%的男性符合新的 mCAFT 切点。mCAFT 切点可用于公共卫生监测、临床和学校环境中识别潜在心血管代谢健康不良风险的儿童和青少年。我们为加拿大儿童和青少年制定了新的 mCAFT 切点来识别潜在的聚集性心血管代谢风险。这些 mCAFT 切点可用于指导国家健康监测工作。
