Listening to music through portable MP3 players has become a very popular mode among young people and adolescents. The aim of this study is to investigate the behaviors of adolescents engaged in listening to music with MP3 player and the attendance at clubs (pubs, discotheques) where music is played at high volume.
Among the 1470 students attending a secondary school in Scandicci (FI) during the school year 2009/2010, 1278 (86.9%) were at school the day of the examination and 1276 completely filled in the questionnaire. Descriptive analysis and univariate and multivariate logistic regression were performed to calculate the degree of association (OR) among the sociodemographic characteristics, listening habits and some factors identified as risky or protective as regards the possibility of developing health disorders.
MP3 player users are 88.2% of the sample. Among these, a high proportion engaged behaviours that increase the risk of presenting disorders, including the exposure to high-volume (27.4%). Furthermore, 44.6% use the MP3 while driving. From the regression analysis it emerges that MP3 users showed a sort of addiction: by increasing the time and the occasions of exposure to music, they increased the volume, used maximum or medium-high volume, did not take breaks and did not decrease the volume.
The study points out the spread of risky behavior in music listening, so it is necessary to better inform especially the youngsters and achieve specific preventive interventions.
通过便携式MP3播放器听音乐已成为年轻人和青少年中非常流行的一种方式。本研究的目的是调查青少年使用MP3播放器听音乐的行为以及在播放高分贝音乐的俱乐部（酒吧、迪斯科舞厅）的出勤情况。
在2009/2010学年就读于斯坎迪奇（佛罗伦萨）一所中学的1470名学生中，1278名（86.9%）在考试当天在校，1276名学生完整填写了问卷。进行描述性分析、单变量和多变量逻辑回归，以计算社会人口统计学特征、听力习惯与一些被确定为与健康障碍发生可能性相关的风险或保护因素之间的关联程度（比值比）。
MP3播放器用户占样本的88.2%。其中，很大一部分人有增加出现障碍风险的行为，包括暴露于高分贝环境（27.4%）。此外，44.6%的人在开车时使用MP3。回归分析表明，MP3用户表现出一种成瘾性：随着听音乐时间和次数的增加，他们提高音量，使用最大音量或中高音量，不休息且不降低音量。
该研究指出了听音乐时危险行为的传播，因此有必要更好地向年轻人提供信息并实施具体的预防干预措施。
