目前美国儿童和青少年的身体活动（PA）指南建议每周7天进行≥60分钟的中度至剧烈强度PA（MVPA），以获得心脏代谢健康（CmH）益处。虽然PA指南的持续时间和强度成分已被严格研究，但频率（7天/周）成分尚未得到彻底研究。检查每周PA指南的频率成分与青年CmH的相关性。来自2003-06年国家健康和营养检查调查的横截面加速度计数据包括年龄6-18岁的青少年，≥4天，≥10小时的佩戴时间，平均MVPA ≥ 60分钟/天（n=656）。根据符合指南（MVPA ≥ 60分钟）的天数比例，将参与者分为四分位数。CmH变量被分类为体重状态/人体测量学、血压、胆固醇和空腹血清实验室。将倾向评分加权应用于四分位数，并使用一般线性模型比较四分位数与CmH变量的相关性。结果显示为符合指南（DMG）的天数百分比（95% CI）; MVPA min/week：Q1（n=156; DMG=45.8%（43.4-48.1）; MVPA 467.5min/周）; Q2（n=165; DMG=62.6%（61.6-63.7）; MVPA 474.4min/周）; Q3（n=148; DMG=75%（74.1-75.8）; MVPA 446.5min/周）; Q4（n=187; DMG=92.2%（87.7-96.6）; MVPA 453.2min/周）。在调整混杂因素和多重比较后，DMG四分位数之间的体重状态/人体测量学、血压、胆固醇或空腹血清实验室检查无临床显著差异。我们发现儿童和青少年DMG和CmH的比例之间没有关联。我们的研究表明，无论PA指南要求的每周7天的频率如何，每周平均60分钟的MVPA似乎足以治疗CmH。
The current physical activity (PA) guidelines for children and adolescents in the U.S. recommend ≥60 minutes of moderate-to-vigorous intensity PA (MVPA), 7 days per week for cardiometabolic health (CmH) benefits. Although the duration and intensity components of the PA guidelines have been rigorously studied, the frequency (7 days/week) component has not been thoroughly researched. To examine the association of the frequency component of the weekly PA guidelines on CmH in youth. Cross-sectional accelerometer data from the 2003–06 National Health and Nutrition Examination Survey included youth aged 6–18 years with ≥4 days, ≥10 hours of wear time, and averaging ≥60min/day of MVPA (n=656). Participants were categorized into quartiles based on the proportion of days where they met the guidelines (≥60min of MVPA). CmH variables were categorized as weight status/body anthropometrics, blood pressure, cholesterol, and fasting serum labs. Propensity score weighting was applied to quartiles and general linear modeling was used to compare associations of quartiles to CmH variables. Results are displayed as percent of days meeting guidelines (DMG) (95% CI); MVPA min/week: Q1 (n=156; DMG=45.8% (43.4–48.1); MVPA 467.5min/week); Q2 (n=165; DMG=62.6% (61.6–63.7); MVPA 474.4min/week); Q3 (n=148; DMG=75% (74.1–75.8); MVPA 446.5min/week); Q4 (n=187; DMG=92.2% (87.7–96.6); MVPA 453.2min/week). After adjusting for confounders and multiple comparisons, there were no clinically significant differences in weight status/body anthropometrics, blood pressure, cholesterol, or fasting serum labs between DMG quartiles. We found no association between proportion of DMG and CmH in children and adolescents. Our study suggests that achieving an overall weekly average of 60 minutes/day of MVPA appears to be sufficient for CmH regardless of the 7 day/week frequency requirement of the PA guideline.
