摘 要：探讨学龄儿童学习日、周末久坐积累模式特征及其与体质健康之间的关系。选取长沙市550名小学生，使用加速度传感器测量并计算不同类型的单次久坐和间断时长，依据《国家学生体质健康标准(2014年修订)》对学龄儿童进行体质健康测评，采用二分类逻辑回归、两分段回归方法，分析学习日、周末久坐积累模式与学龄儿童体质健康的关系。结果：(1)学龄儿童学习日及周末的久坐积累模式均呈“碎片化”特征，学习日更偏向于长时性久坐与MVPA间断，周末则更倾向于短时性久坐与LPA间断。(2)学龄儿童学习日久坐总时长(OR=1.011，95%CI：1.007~1.015，P＜0.001)、单次≥30 min久坐(OR=1.016，95%CI：1.008~1.024，P＜0.001)为其体质健康的风险因素，≥5min MVPA间断(OR=0.962，95%CI：0.941~0.983，P＜0.001)则为保护因素；周末仅久坐总时长(OR=1.004，95%CI：1.001~1.007，P=0.007)为体质健康的风险因素。(3)学习日单次≥5 min MVPA间断与体质健康之间存在非线性关系(P =0.005)。当≥5 min MVPA时长≤36.6 min/天时，每增加1 min/天，体质健康未达标优良的比率降低5.6%(OR=0.944，95%CI：0.921~0.967，P =0.005)；而当≥5 min MVPA时长＞36.6 min/天时，每增加1 min/天，体质健康未达标优良的比率无显著变化(OR=1.032，95%CI：0.981~1.085，P =0.221)。结论：学习日限制学龄儿童久坐总时长的同时也应将单次久坐时长限制在30 min之内，鼓励单次持续5 min以上的MVPA并每天达到36.6 min，而周末干预重点在于限制久坐总时长。

Abstract: To explore the characteristics of sedentary accumulation pattern on weekdays and weekends in preschool children and their relationships with physical health. A total of 550 primary school students from Changsha were selected, and using accelerometers to measure and calculate different types of sedentary bouts and break of different intensities. According to the requirements of the “National Students’ Physical Health Standards (Revised in 2014)”, the physical health of children was assessed. A binary Logistic regression and segment regression analysis were examined the relationships of accumulation pattern on weekdays and weekends, and children’s physical health. Results: (1) The sedentary accumulation pattern on weekdays and weekends for preschool children both exhibited a fragmented characteristic. On weekdays, longer sedentary periods and MVPA break were more common, while on weekends, shorter sedentary periods and LPA break were more frequent. (2) On weekdays and for preschool children, the total sedentary time (OR=1.0111, 95% CI: 1.007-1.015, P < 0.001) and sedentary bout≥30minutes (OR=1.016, 95% CI: 1.008-1.024, P < 0.001) were identified as risk factors for physical fitness, while≥5min MVPA (OR=0.962, 95% CI: 0.941-0.983, P < 0.001) was a protective factor. On weekends, only total sedentary time (OR=1.004, 95% CI: 1.001-1.007, P = 0.007) was a risk factor for physical health. (3) Non-linear relationship between≥5 min MVPA break and physical fitness on weekdays (P = 0.005). When the≥5min MVPA was≤36.6 minutes per day, each additional minute per day decreased the rate of good-excellent physical health by 5.6% (OR=0.944, 95%CI: 0.921-0.967, P = 0.005). However, when the≥5min MVPA>36.6 minutes per day, each additional minute per day did not significantly affect the rate of good-excellent physical health (OR=1.032, 95% CI: 0.981-1.085, P = 0.221). Conclusion: On weekdays, except for limiting total sedentary time, sedentary bouts should be restricted to no more than 30 minutes, while encouraging sustained≥5min MVPA break to reach a daily total of 36.6 minutes, and on weekends, the focus should be on limiting total sedentary time.
