Introduction: Noise-induced hearing loss is a major public health problem. Extended exposure
to noisy music can cause not only hearing loss, but also biochemical changes in exposed Disc Jockey
(DJ) workers. Aim of work: To study some health hazards; mainly biochemical changes and hearing
threshold levels among DJ workers compared with a well-matched control group and the prevalence
of using protective measures among this occupational group. Materials and methods: A crosssectional controlled study was conducted at Benha city, Kalyobiya Governorate, Egypt. Data was
collected from the beginning of May till the end of September 2017. Sixty-three DJ workers and
well-matched seventy-two ofÀce workers were subjected to an interview structured questionnaire,
clinical examinations including audiometric hearing threshold assessment, biochemical analysis and
Framingham coronary heart disease risk score was calculated. Results: The hearing threshold was
affected in 59% of DJ workers. Blood pressure, pulse and lipid proÀle were statistically signiÀcantly
higher in DJ workers (except HDL was lower). The difference in audiometric measures starts at
3000 at right ear and 4000 at left ear. The only signiÀcant predictor for hearing affection was work
duration. Conclusion: Noise is one of the disturbing factors for health. In addition to impairing of
hearing, noise affects blood pressure, blood glucose and lipid proÀles which acts as risk factor for
cardio vascular diseases. |
