【摘要】：目的·通过了解重庆市主城区中小学男生首次遗精发生情况,探讨首次遗精发生年龄与体力活动和睡眠时间的关系。方法·采用分层随机整群抽样抽取重庆市主城区男生3 403人(10~18岁),进行体格检查和问卷调查,选择其中经历首次遗精的1 282人作为研究对象。根据首次遗精发生年龄,分为适时组(964人)和较晚组(318人)。结果·2组在平均每周进行高等(χ~2=11.488,P=0.009)、中等(χ~2=7.829,P=0.050)强度体力活动,平均每天睡眠时间(χ~2=17.803,P=0.000)构成上均存在差异。控制年龄、身高、体质量等协变量,与适时组相比,较晚组的男生更少进行每周5~7 d(OR=0.596,95%CI:0.367~0.967)和3~4 d(OR=0.590,95%CI:0.370~0.941)高等强度体力活动,也更少有平均每天9~11 h(OR=0.207,95%CI:0.088~0.489)睡眠时间。结论·男生首次遗精发生年龄可能与其每周进行体力活动的强度和每天睡眠时间有关。
[Abstract]:Objective to investigate the relationship between the age of first spermatozoa and physical activity and sleep time in primary and middle school boys in Chongqing. Methods A stratified random cluster sampling was used to select 3 403 male students (10 ~ 18 years old) from the main urban area of Chongqing. The physical examination and questionnaire survey were conducted, and 1 282 of them who had experienced the first spermatozoa were selected as the research objects. According to the age of the first spermatozoa, they were divided into timely group (964) and late group (318). Results there were significant differences between the two groups in the composition of physical activity of high intensity (蠂 ~ 2 / 2) and moderate (蠂 ~ (2 / 2) 7.829 / P ~ (0.050) and average daily sleep time (蠂 ~ (2 / 2) = 17.803 / P ~ (0.000) in the two groups (蠂 ~ (2 / 2) = 11.488 / P ~ (0.009). Control age, height, body mass and so on. Compared with the timely group, the boys in the later group had less physical activity of higher intensity for 5 days a week (ORO 0.596 + 95CI: 0.3670.967) and 3days (ORO 0.590 95CI: 0.3707: 0.941), and less sleep time for an average of 9 hours a day (ORO 0.20795 CI: 0.0888.0.489). Conclusion the age of first spermatozoa in male students may be related to the intensity of physical activity and the daily sleep time.
