The aim of this study was to measure the frequency of hearing loss in a sample of typical public high-school students exposed to recreational noise, and determine associated risk factors. The sample was made up of 214 teenagers from a high-school in Mexico City; subjects were selected randomly per strata. We applied a questionnaire to identify risk factors for hearing loss and performed a battery of audiologic tests consisting of otoscopy, tympanometry, and pure-tone audiometry. The mean age of the sample was 16 ± 1.07 years; 73% were male and 27%, female. Hearing loss was found in 21% of students. The main hearing loss-related risk factor was exposure to recreational noise: frequent attendance at discotheques and pop-music concerts; use of personal stereos; and noise exposure in school workshops. The high frequency of hearing loss in high school students from one Mexico City school (nearly one fifth of the sample) was found to be related to noise exposure mainly during recreational activities.

Although the rate of sexual intercourse among adolescents has increased in Asian countries, including Korea, many sexually active adolescents still do not use contraception. The aim of this study was to identify the risk factors for contraceptive nonuse among adolescents using decision tree analysis of the 2018 Korea Youth Risk Behavior Survey data from 2,460 high school students who had an experience of sexual intercourse. The findings indicated that the highest risk group who did not use contraception during sexual intercourse did not receive sexual health education in school and was involved in habitual or purposeful drug use. The experience of ever receiving treatment due to violence and the experience of sexual intercourse after drinking were also identified as risk factors for contraceptive nonuse. To encourage contraceptive use, development of standard sexual health education, counseling, and educational intervention intended to prevent risky behaviors is needed.
