Bilateral high-frequency hearing loss is associated with elevated blood #pressure and increased hypertension risk in occupational #noise exposed workers

..bilateral high-frequency hearing loss (BHFHL)

Increasing years of occupational noise exposure and BHFHL were significantly associated with systolic and diastolic blood pressure increase (all P<0.001). The lineal trend was only significant in males, with adjusted ORs for hypertension gradually increasing with increasing years of occupational noise exposure (P<0.001). Furthermore, subjects having mild and high BHFHL had a higher hypertension risk of 34% and 281%, respectively (both P<0.001). Dose-response relationship between BHFHL and hypertension was found in both males and females.

Occupational noise exposure was positively associated with blood pressure levels and hypertension risk.
