摘要
目的了解中小学生身体活动、能量消耗及睡眠现状,为制定学龄期身体活动相关健康干预措施提供依据。方法采用分层随机整群抽样方法,在国际体力活动问卷(IPAQ)基础上调整设计问卷,调查沈阳、广州、成都、武汉4城市的10 909名中小学生的身体活动及睡眠状况,并进行性别、学段、城市间的比较。结果调查对象每周平均有(4.0±1.9)d、每天(44.9±39.5)min参加中等强度身体活动,有(3.1±1.8)d、平均每天(38.5±38.5)min参加高强度身体活动,身体活动能量代谢当量平均每周为(1602.2±1939.3)MET-miniutes,每周达到中等和高身体活动水平的学生分别占29.1%和31.5%;男生的身体活动强度和时间高于女生,低学段高于高学段,城市间存在差异。调查对象每天闲暇时平均静坐活动时间为(158.6±154.3)min,53.7%的人每天静坐活动2 h及以上,随着学段升高,静坐活动时间和比例升高。平均每天睡眠时间为(7.7±1.6)h,睡眠不足的比例是79.9%,女生高于男生,高学段高于低学段。结论中小学生中高身体活动水平比例较低,静坐活动时间较长,睡眠不足的比例较高,性别、学段和城市间存在差异。
Objective To understand the status of physical activity and sleeping status among students in primary and secondary school, and provide evidence for the health intervention strategies in order to boost physical activity. Methods Random cluster sampling method was applied for the investigation. Among students from Shenyang, Guangzhou, Chengdu and Wuhan, information about intensity and duration of physical activity, sedentary activity and sleeping hours were collect- ed by a self-reported questionnaire, which was derived from International Physical Activity Questionnaire （IPAQ）. This present study also analyzed and compared the indicators among different genders, school stages and cities. Results Totally 10 909 students were enrolled in this survey, the participants did moderate physical activity for （44. 9 ＋ 39. 5 ） minutes/clay and （4. 0 _＋ 1.9） days/week, rigorous physical activity for （38. 5 ~ 38. 5） minutes/day and （3.1 ＋ 1.8） days/ week. Physical activity energy consumption was （ 1602. 2 ＋ 1939. 3 ） MET-minintes in a week, 31.5% of students met high level of physical activity according to IPAQ criteria and 29. 1% of them met moderate level. As to intensity and duration of physical activity, boys were higher than girls, students in higher school grade were lower, and differences were found a- mong different cities. Participants spent （ 158. 6 ± 154.3） minutes on sedentary activity every day, 53.7% of them engaged in this activity for 2 hours and above. There were （7. 7± 1.6） hours spent on sleeping on a typical day, and 79. 9% of students suffered from insufficient sleep, the numbers were higher in females than males, and higher in students in higher school grade. Conclusion The physical activity level of students was fairly low, duration of sedentary activity was long, and majority of subjects lacked sleep, the differences was statistically significant among gender, school grade and cities.
