This is a cross-sectional school-based study, with the participation of 306 adolescents aged 14 to 18 years. A questionnaire with structured questions was applied to collect data on physical activity, screen time, and sleep duration. Cardiometabolic health was assessed by the calculation of a continuous risk score, including twelve markers related to body fat, blood pressure, plasma lipids and lipoproteins, glycemia, and insulin.
Only 4.8% (4.3-5.4) of the adolescents met the three healthy movement behavior guidelines, while 9.3% (8.4-10.4) of the sample did not meet any of the guidelines. No significant difference between sexes was found in the simultaneous compliance of the three movement guidelines. Adolescents who did not meet any of the movement guidelines were twice as likely to have higher cardiometabolic risk (OR = 2.05 (1.41-3.17)) than their peers who met all three guidelines.
Considering the high proportion of adolescents who did not meet the movement behavior guidelines and the negative effects on cardiometabolic health, it is suggested that future policies and interventions should consider an integrated and holistic approach aimed at simultaneous actions of maximizing physical activity, minimizing screen time, and ensuring sufficient sleep duration.
这是一项基于学校的横断面研究,参与了306名14至18岁的青少年。使用带有结构化问题的问卷来收集有关身体活动的数据,屏幕时间,和睡眠时间。通过计算连续风险评分来评估心脏代谢健康,包括与身体脂肪有关的十二个标记,血压,血浆脂质和脂蛋白,血糖,和胰岛素。
只有4.8%(4.3-5.4)的青少年符合三项健康运动行为指南,而9.3%(8.4-10.4)的样本不符合任何指南。在同时遵守三个运动指南方面,性别之间没有显着差异。不符合任何运动指南的青少年的心脏代谢风险(OR=2.05(1.41-3.17))是符合所有三个指南的同龄人的两倍。
考虑到不符合运动行为指南的青少年比例很高,以及对心脏代谢健康的负面影响,建议未来的政策和干预措施应考虑采取综合和整体的方法,旨在同时采取最大限度地提高身体活动的行动,最小化屏幕时间,保证充足的睡眠时间。
