Abstract:
Objective:To explore the relationship between the binaural high-frequency mean hearing threshold and the hypertension of female workers exposed to noise, and to understand the application significance of the binaural high-frequency mean hearing threshold as an internal effect indicator of the risk of hypertension in female workers exposed to noise.Methods:From January to December 2018, a total of 20882 female workers exposed to noise in Guangzhou were selected by cluster sampling. Pure tone audiometry, blood pressure, age and length of service were collected. Trend test was used to evaluate the effects of exposure to noise and binaural high-frequency mean hearing threshold on blood pressure. Binary logistic regression model was used to evaluate the risk of hypertension associated with exposure to noise and binaural high-frequency mean hearing threshold.Results:The detection rate of normal hearing threshold, mild hearing loss and severe hearing loss was 80.73% (16858/20882) , 16.21% (3384/20882) and 3.06% (640/20882) respectively. The prevalence of hypertension was 6.04% (1018/16858) in normal hearing group, 10.28% (348/3384) in patients with high frequency mild hearing loss, and 11.25% (72/640) in patients with high frequency severe hearing loss. There was a linear relationship between the increase of working age and high-frequency mean hearing threshold and the increase of systolic and diastolic blood pressure ( P< 0.05) . Compared with those exposed to noise for less than 1 year, the risk of hypertension in female workers with 7-9 years and more than 9 years was decreased ( OR= 0.79, 0.75, P<0.05) . Compared with normal hearing group, the risk of hypertension in high frequency mild hearing loss group was increased ( OR=1.31, P<0.05) . Conclusion:The increase in the binaural high-frequency mean hearing threshold of female workers exposed to noise can increase the blood pressure level and the risk of hypertension, and attention should be paid to female workers with high-frequency mild hearing loss.
