This study aimed to develop and validate health-related criterion-referenced cut-points for the modified Canadian Aerobic Fitness Test (mCAFT), a field-based measure to predict cardiorespiratory fitness among adults (18-69 years). Criterion-referenced mCAFT cut-points were developed using nationally representative data from cycles 1 (2007-2009) and 2 (2009-2011) of the Canadian Health Measures Survey (CHMS). Receiver operating characteristic curves were used to identify age- and sex-specific cut-points for measured waist circumference, blood pressure, and high-density lipoprotein. Cut-points were validated against metabolic syndrome using a fasted subsample ( = 1093) from cycle 5 (2016-2017). For the main analyses, 4967 participants (50% women) were retained. The mCAFT cut-points ranged from 28 to 43 mL·kg·min (area under the curve (AUC): 0.60-0.87) among men, and 23 to 37 mL·kg·min (AUC: 0.61-0.86) among women. The likelihood of meeting the new mCAFT cut-points decreased with an increase in the presence of metabolic risk factors. In total, 54% (95% confidence interval: 42% to 67%) of Canadian adults met the new mCAFT cut-points in 2016-2017. This study developed and validated the first health-related criterion-referenced mCAFT cut-points for metabolic health among Canadian adults aged 18-69 years. These mCAFT cut-points may be useful in health surveillance, clinical, and public health settings. We developed and validated new criterion-referenced cut-points for the mCAFT to help identify adults at potential risk of poor metabolic health. These new cut-points could help support national health surveillance efforts.
本研究旨在为改良加拿大有氧适能测试（mCAFT）制定和验证与健康相关的标准参照切点，该测试是一种基于现场的成年人心肺适能预测指标（18-69 岁）。使用来自加拿大健康测量调查（CHMS）第 1 周期（2007-2009 年）和第 2 周期（2009-2011 年）的全国代表性数据制定了与健康相关的 mCAFT 切点。使用受试者工作特征曲线来确定针对腰围、血压和高密度脂蛋白的特定年龄和性别的切点。使用第 5 周期（2016-2017 年）的空腹亚样本（n=1093）对代谢综合征进行了验证。在主要分析中，保留了 4967 名参与者（50%为女性）。mCAFT 切点范围为男性 28-43 mL·kg·min（曲线下面积（AUC）：0.60-0.87），女性 23-37 mL·kg·min（AUC：0.61-0.86）。符合新的 mCAFT 切点的可能性随着代谢风险因素的增加而降低。总的来说，2016-2017 年，54%（95%置信区间：42%-67%）的加拿大成年人符合新的 mCAFT 切点。本研究制定并验证了第一个与健康相关的改良加拿大有氧适能测试的切点，用于评估 18-69 岁加拿大成年人的代谢健康状况。这些 mCAFT 切点可用于健康监测、临床和公共卫生环境。我们开发并验证了 mCAFT 的新的标准参照切点，以帮助识别有潜在代谢健康不良风险的成年人。这些新的切点可以帮助支持国家健康监测工作。
