摘　　要：目的探讨青少年日常身体活动量与青春期性发育水平的关系,为采取针对性的干预措施提供依据。方法采用多阶段整群抽样法,选取上海市中小学生共1 348名,调查年龄、性发育水平、父母文化程度和日常身体活动情况。结果女生乳房、阴毛、腋毛的发育水平与中高水平身体活动量呈负相关(r值分别为-0.067,-0.074,-0.078,P值均<0.05),男、女生性发育水平与学习日r值分别为0.117,0.134,0.177,0.158,0.137,0.156,0.181,0.156,和周末r值分别为0.085,0.106,0.588,0.115,0.130,0.153,0.157,0.189的静态行为时间均呈正相关(P值均<0.05)。在控制年级和父母平均受教育程度的混杂作用下,男生腋毛和胡须发育水平每增加1级,学习日静态行为时间≥120 min的可能性分别增加了0.79和0.78倍;腋毛发育水平每增加1级,周末静态行为时间≥265 min的可能性增加了0.49倍;已经月经来潮女生中高水平身体活动量和周末静态行为时间≥265 min的可能性分别是月经未来潮女生的2.11和2.10倍。结论青少年性发育水平与身体活动量之间存在独立的关联性。应针对不同青春期发育阶段的青少年采取适宜的干预措施。Objective To explore the relationship between adolescent pubertal development status and daily physical activity.

Age, pubertal development, parental educations and daily physical activity were investigated.Results It showed negative correlation between girls＂ breast, pubic hair and armpit hair development levels with moderate-vigorous physical activity. Sedentary behavior positively related with pubertal development in beth boys and girls. Controlling the confounding effects of grade and parental education, armpit hair and facial hair development of boys was protective for sedentary behavior of weekdays（ r = 0.79,0.78, respectively）. The armpit hair development levels of boys＂ for each additional level, the possibility of sedentary behavior of weekends increased 0.49 times. The possibility of moderate-vigorous physical activity and sedentary behavior of weekends was 2.11 and 2.10 times in girls who had menarche than girls those did not.
