本研究旨在探讨青少年中到剧烈体力活动与心脏代谢指标之间的剂量反应关系。使用2003-2016年全国青少年健康与营养调查数据进行横断面样条分析（12-19岁，N= 9，195）（2003-2006年）和自我报告的每周平均分钟数（2007-2016年）的中度至剧烈体力活动和心脏代谢指标（收缩压和舒张压，总胆固醇，高密度脂蛋白，体重指数和心肺功能。确定了非线性关系的拐点。对于客观的中度到剧烈的体力活动，女性青少年在90分钟/周时BMI百分位数和收缩压的拐点有显着的非线性关联。男性青少年在每周150分钟的客观活动的BMI百分位数和心肺功能的拐点。在每周150分钟客观测量的中度至剧烈体力活动时，女性和男性青少年的BMI百分位数比0分钟低约7%。对于自我报告的中度至剧烈体力活动，拐点为375分钟/周（女性青少年的舒张压）和500分钟/周（男性青少年的收缩压）。在青少年体力活动和心脏代谢健康之间的几个显著剂量-反应关系中，确定了BMI的一致性和通常的非线性关系，拐点在90-150分钟的客观中度到剧烈的体力活动。通过性别和体力活动测量（客观或自我报告）确定了相关性和线性的显著差异。这些结果支持青少年增加身体活动的呼吁，并表明更接近成人指导方针的建议，即每周150分钟的身体活动可能有利于健康，而且比目前建议的每周420分钟更容易实现。
This study examines the dose–response relationship between moderate-to-vigorous physical activity and cardiometabolic measures in adolescents. Cross-sectional spline analyses were performed using 2003–2016 National Health and Nutrition Examination Survey data among adolescents (aged 12–19 years, N=9,195) on objectively measured (2003–2006) and self-reported weekly mean minutes (2007–2016) of moderate-to-vigorous physical activity and cardiometabolic measures (systolic and diastolic blood pressure, total cholesterol, high-density lipoprotein, BMI, and cardiorespiratory fitness. Inflection points were determined for non-linear relationships. For objective moderate-to-vigorous physical activity, female adolescents had significant non-linear associations with inflection points at 90 minutes/week for BMI percentile and systolic blood pressure. Male adolescents had inflection points at 150 weekly minutes of objective activity for BMI percentile and cardiorespiratory fitness. BMI percentile was about 7% lower for female and male adolescents at 150 weekly minutes of objectively measured moderate-to-vigorous physical activity versus 0 minutes. For self-reported moderate-to-vigorous physical activity, inflections points were at 375 minutes/week (diastolic blood pressure for female adolescents) and 500 minutes/week (systolic blood pressure for male adolescents). Among several significant dose–response relationships between physical activity and cardiometabolic health in adolescents, consistent and often non-linear relationships were identified for BMI, with inflection points at 90–150 minutes of objective moderate-to-vigorous physical activity. Notable differences in associations and linearity were identified by sex and physical activity measure (objective or self-report). These results support calls for any increase in physical activity among adolescents and suggest that recommendations closer to the adult guidelines of 150 weekly minutes of physical activity may be health promoting and more attainable for youth than the current recommendation of 420 weekly minutes.
