The authors aimed to examine the association between meeting the integrative movement behavior guidelines (physical activity, screen viewing, and sleep) and cardiometabolic risk (CMR) factors in young children.
In this cross-sectional study, physical activity, screen viewing, and sleep were assessed using parent-reported data. The 24-Hour Movement Guidelines for the Early Years (0-4 y) were defined as 180 minutes of physical activity/day (of which ≥60 min should be moderate-to-vigorous intensity), ≤1 hour of screen viewing/day, and 10 to 13 hours of sleep/night. Waist circumference, glucose, high-density lipoprotein cholesterol, triglycerides, and systolic blood pressure were measured in a clinical setting by trained staff. A total CMR score and individual CMR factors served as primary and secondary outcomes, respectively.
Of the 767 participants (3-4 y), 26.4% met none of the guideline's recommendations, whereas 41.3%, 33.1%, and 10.6% of the sample met 1, 2, or all 3 recommendations, respectively. The number of recommendations met was not associated with the total CMR score or individual CMR factors (P > .05), with the exceptions of high-density lipoprotein (odds ratio = 1.61; 95% confidence interval, 1.11 to 2.33; P = .01).
Meeting the 24-Hour Movement Guidelines in early childhood was not associated with overall CMR, but was associated with favorable cholesterol outcomes.
本研究旨在探讨儿童期符合综合运动行为指南（体力活动、屏幕时间和睡眠）与心血管代谢风险（CMR）因素之间的关系。
在这项横断面研究中，使用家长报告的数据评估体力活动、屏幕时间和睡眠。《0-4 岁儿童 24 小时运动指南》将 180 分钟/天的体力活动（其中≥60 分钟应是中等到剧烈强度）、每天≤1 小时的屏幕时间和 10-13 小时/夜的睡眠时间定义为符合指南的标准。由经过培训的工作人员在临床环境中测量腰围、血糖、高密度脂蛋白胆固醇、甘油三酯和收缩压。总 CMR 评分和单个 CMR 因素分别作为主要和次要结局。
在 767 名参与者（3-4 岁）中，26.4%的人不符合指南的任何建议，而 41.3%、33.1%和 10.6%的人分别符合 1、2 或 3 项建议。符合指南建议的数量与总 CMR 评分或个别 CMR 因素无关（P＞0.05），但高密度脂蛋白除外（比值比=1.61；95%置信区间，1.11-2.33；P=0.01）。
儿童早期符合 24 小时运动指南与整体 CMR 无关，但与良好的胆固醇结果相关。
