Relationship between physical activity and physical health of preschool children in Tibet

doi:10.11852/zgetbjzz2024-0986

Abstract

Abstract: Objective To investigate the relationship between different levels of physical activity, sedentary time, and physical health among preschool children (aged 3 - 6 years) in specific regions of Tibet. Methods Data were obtained from the Tibetan National Physical Fitness Monitoring database, including 1 035 preschool children as study subjects. The physical fitness test assessed both body shape and physical function. The chi-square test and binary logistic regression models were used to analyze factors affecting physical health. Results The overall physical fitness qualification rate among preschool children in these Tibetan regions was 84.25%, significantly lower than the national average (P<0.001). Children exercising 3 - 4 times per week, for 30 - 120 minutes per session, and with sedentary time <2 hours per day, achieved better total physical fitness scores (P<0.05). Compared to the reference group (exercising <3 times/week), logistic regression showed that physical activity significantly increased the odds of passing the fitness qualification. This effect was observed in normal-weight preschool children (3 - 4 times/week: OR=23.88; ≥5 times/week: OR=9.54), obese children (3 - 4 times/week: OR=3.87), and children with high body fat (≥10.10%) (3 - 4 times/week: OR=9.65;≥5times/week:OR=4.97;60 - 120 min/session: OR=12.11) (all P<0.05). Conclusion Controlling sedentary time (<2h/d) and increasing physical activity (30 - 120min/session, 3 - 4 times/week) are crucial strategies for improving the physical fitness of preschool children in Tibet. For obese preschool children and those with high body fat, increasing both the frequency and duration of exercise is essential for enhancing their physical health outcomes.

摘要： 目的探讨西藏部分地区学龄前儿童不同体育锻炼程度、久坐时间与体质健康的关系。方法数据来源于西藏国民体质监测(幼儿部分),共纳入1 035名学龄前儿童为研究对象。体质测试内容包括身体形态及身体素质。采用卡方检验和二元logistic回归模型分析影响幼儿体质健康的因素。结果西藏部分地区学龄前儿童体质总合格率为84.25%,显著低于全国平均水平 (P<0.001)。学龄前儿童体质总分在锻炼频率为3~4次/周、锻炼时间为30~120分钟/次、久坐时间<2h/d的组别中表现更优 (P<0.05)。logistic回归分析显示,与低运动量(<3次/周)相比,体育锻炼能显著提高体质合格率:在正常体重学龄前儿童中,锻炼3~4次/周 (OR=23.88) 和≥5次/周 (OR=9.54) 效果显著;在肥胖幼儿中,锻炼3~4次/周 (OR=3.87) 效果显著;在高体脂率(≥10.10%)学龄前儿童中,锻炼3~4次/周 (OR=9.65)、≥5次/周 (OR=4.97) 以及锻炼60~120min/次(OR=12.11)其体质合格率更高(P<0.05)。结论控制久坐时间(<2h/d)并加强体育锻炼(30~120min/次, 3~4次/周)是提高西藏学龄前儿童体质的重要策略。对于肥胖及高体脂率的学龄前儿童,增加体育锻炼的频率和时长对改善其体质健康具有重要意义。
