ABSTRACT
Objective@#To investigate the relationship between the use of earphone and hearing impairment and its influencing factors among students aged 14-28, so as to provide a reference for appropriate earphone usage and hearing impairment prevention.@*Methods@#A cross sectional survey was conducted through the questionnaire star platform, and 983 students aged 14 to 28 were recruited across China by snowball sampling during April 3 to May 1, 2022. The χ 2 test was used to identify indicators affecting hearing, the Logistic regression model was used to further selection.@*Results@#There were 366 students with hearing impairment, accounting for 37.23%. Univariate analysis showed significant differences in hearing impairment by gender, earphone usage duration and volume, wearing during sleep, and replacement frequency ( χ 2=6.03, 6.86, 14.87, 12.22, 11.15, P <0.05). The Logistic regression model analysis showed that girls ( OR=1.43, 95%CI =1.10-1.88), maximum earphone volume ( OR=3.08, 95%CI = 1.56- 6.08), earphone usage for >1.5-3 h each time ( OR=1.44, 95%CI =1.04-1.99), sleep with headphone ( OR= 1.53 , 95%CI = 1.11- 2.11) were positively associated with hearing impairment ( P <0.05), earphone replacement every 4-<6 months ( OR= 0.38, 95%CI =0.17-0.86) and earphone replacement every six months or longer ( OR=0.39, 95%CI =0.18-0.85) were negatively associated with hearing impairment ( P < 0.05 ).@*Conclusion@#Students aged 14 to 28 earphone usage shows adverse impact on hearing. When using earphone, it is recommended to limit time spent on earphone usage, low the volume of earphone, avoid sleeping with earphone and replace earphone frequently.
ABSTRACT
Objective@#To investigate the current situation of hearing health among college students and associated factors, and to provide a basis for universities and relevant departments to carry out hearing health work.@*Methods@#By using stratified random sampling method, 1306 students from 4 universities in Taiyuan were screened for hearing loss and were investigated with a questionnaire from March to November 2021. Data were analyzed by using the SPSS 19.0 statistical.@*Results@#The detection rate of hearing loss was 31.70%. The majority (51.91%) failed to pass the 4 000 Hz hearing screening. The total awareness rate of hearing problems was 58.96%. Logistic regression analysis showed that the total daily usage time of earphones >4 h/d, the duration of using earphones >1 h/time were positively correlated with positive screening for hearing loss among college students( OR=1.23, 1.14, P < 0.01), and good awareness of hearing health care and highest education of parents were negatively correlated with positive screening for hearing loss among coollege students( OR =0.54, 0.76, 0.37, P <0.05).@*Conclusion@#The awareness of hearing health care among college students is low. Universities and relevant departments should take targeted measures to provide the best hearing health care services.
