CORRELATION OF MALONDIALDEHYDE AND HEARING THRESHOLD LEVEL AT FREQUENCY 4000 HZ POST GUNSHOT EXPOSURE
Background: The incidence of acoustic trauma after gunshot exposure in students of the Sekolah Polisi Negara (SPN) is quite high. Malondialdehyde (MDA) is a compound that can portray oxidative stress due to free radicals. The correlation between the levels of MDA and the hearing threshold frequenc...

Malondialdehyde (MDA) is a compound that can portray oxidative stress due to free radicals. The correlation between the levels of MDA and the hearing threshold frequency post gunshot exposure could be used as the base for administering antioxidants to prevent acoustic trauma. Objective: To find out the correlation between the levels of MDA and the hearing threshold frequency post gunshot exposure, in East Java SPN students. Method: An observational analytic study with a retrospective cross sectional approach using secondary data of medical records of the East Java SPN students batch 2017/2018. The samples were selected by simple random sampling. Result: Out of 50 students, the mean of age was 19.62 years. All samples were male with mean 559.17 and standard deviation (SD) 959.86. The calculation of the 4000 Hz frequency threshold value obtained an average value of 31.52 and SD of 13.4. Hearing loss complaint was found in 1 student (2%). No complaints of tinnitus and vertigo were found. Statistical tests with Pearson correlation between serum MDA levels and 4000 Hz frequency threshold values showed a correlation coefficient (r) of 0.74 and p = 0.00 (p<0.05). Conclusion: There was a significant correlation between MDA levels and the hearing threshold at 4000 Hz frequency after gunshot exposure in East Java SPN students.

Background: The incidence of acoustic trauma after gunshot exposure in students of the Sekolah
Polisi Negara (SPN) is quite high. Malondialdehyde (MDA) is a compound that can portray oxidative
stress due to free radicals. The correlation between the levels of MDA and the hearing threshold frequency
post gunshot exposure could be used as the base for administering antioxidants to prevent acoustic
trauma. Objective: To find out the correlation between the levels of MDA and the hearing threshold
frequency post gunshot exposure, in East Java SPN students. Method: An observational analytic study
with a retrospective cross sectional approach using secondary data of medical records of the East Java
SPN students batch 2017/2018. The samples were selected by simple random sampling. Result: Out of
50 students, the mean of age was 19.62 years. All samples were male with mean 559.17 and standard
deviation (SD) 959.86. The calculation of the 4000 Hz frequency threshold value obtained an average
value of 31.52 and SD of 13.4. Hearing loss complaint was found in 1 student (2%). No complaints of
tinnitus and vertigo were found. Statistical tests with Pearson correlation between serum MDA levels and
4000 Hz frequency threshold values showed a correlation coefficient (r) of 0.74 and p = 0.00 (p<0.05).
Conclusion: There was a significant correlation between MDA levels and the hearing threshold at 4000
Hz frequency after gunshot exposure in East Java SPN students. |
