The influence of mobile phone addiction (MPA) on physical exercise in university students was explored, and peer relationships were introduced as a moderating variable.
A cross-sectional study design was adopted, and an online survey questionnaire was conducted to investigate two universities in Nantong City, Jiangsu Province, and Chongzuo City, Guangxi Zhuang Autonomous Region. A total of 4959 university students completed the questionnaire. Measurement tools included the Mobile Phone Addiction Tendency Scale, the Physical Activity Rating Scale, and the Peer Rating Scale of university students.
University students scored 39.322 ± 15.139 for MPA and 44.022 ± 7.735 for peer relationships, with 87.8% of their physical exercise, in terms of exercise grade, being classified as medium or low intensity. The MPA of the university students was negatively correlated with peer relationships (r = -0.377, < 0.001) and physical exercise behavior (r = -0.279, < 0.001). The moderating effect of peer relationships on the MPA-physical exercise behavior relationship was significant (ΔR = 0.03, < 0.001).
The physical exercise of university students was at a medium or low intensity. The more serious the university students' addiction to mobile phones was, the lower the amount of physical exercise. The physical activity of males was higher than that of females. MPA and peer relationships were the limiting factors of the physical exercise behavior of university students. Under the lower effect of peer relationship regulation, MPA had a greater negative impact on physical exercise behavior. The data from this research can provide theoretical support to improve the participation of university students in physical activities.
探讨大学生手机成瘾（MPA）对体育锻炼的影响，并引入同伴关系作为调节变量。
采用横断面研究设计，对江苏省南通市和广西壮族自治区崇左市的两所高校进行在线问卷调查，共 4959 名大学生完成了问卷。测量工具包括手机成瘾倾向量表、体育活动等级量表和大学生同伴评价量表。
大学生的手机成瘾得分为 39.322±15.139，同伴关系得分为 44.022±7.735，运动等级 87.8%为中低强度。大学生的手机成瘾与同伴关系（r=-0.377，<0.001）和体育锻炼行为（r=-0.279，<0.001）呈负相关。同伴关系对手机成瘾与体育锻炼行为关系的调节作用显著（ΔR=0.03，<0.001）。
大学生的体育锻炼处于中低强度水平。大学生手机成瘾越严重，体育锻炼量越低。男生的体育活动量高于女生。MPA 和同伴关系是大学生体育锻炼行为的限制因素。在同伴关系调节作用较低的情况下，MPA 对体育锻炼行为的负面影响更大。本研究数据可为提高大学生参与体育活动的积极性提供理论支持。
