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（χ2=11.488，P=0.009）、中等（χ2=7.829，P=0.050）强度体力活动，平均每天睡眠时间（χ2=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 understand boys’ pubertal timing in school in two urban districts of Chongqing and explore the relationship between pubertal timing and physical activity or sleeping time. Methods · Using a stratified random cluster sampling, 3 403 boy students (10-18 year-old) were selected and completed the physical examination and questionnaire survey. 1 282 participants experiencing first spermatorrhea were chosen as research objects. According to age of first spermatorrhea, the objects were divided into on-time group (964 cases) and later group (318 cases). Results · The composition of weekly high (χ2=11.488, P=0.009), medium (χ2=7.829, P=0.050) physical activity and daily sleeping time (χ2=17.803, P=0.000) in two groups were significantly different. Controlling covariates (age, height and weight), compared with boys in on-time group, later group boys were less likely to engage in 5-7 days (OR=0.596, 95% CI: 0.367-0.967) and 3-4 days (OR=0.590, 95% CI: 0.370-0.941) high physical activity every week, and 9-11h (OR=0.207, 95% CI: 0.088-0.489) sleep every day. Conclusion · The age of first spermatorrhea in boys might be associated with the intensity of weekly physical activity and daily sleeping time.
