Effect of cigareet smoking on air-conduction hearing threshold level in adult men.: Jin Seok Kim, Min Hae Yeh, Byung Yeol Chun, Kuck Hyeun Woo, Yune Sik Kang, Keon Yeop Kim, Young Sook Lee; Korean J Prev Med. 1998;31(2):285-292.

Abstract PDF: To investigate the effect of smoking on the hearing threshold, l,887 adult male workers who visited health care center during the period l January 1996 - 31 July 1997 were selected. Air-conduction hearing threshold level, diastolic blood pressure(DBP), total cholesterol, fasting blood sugar(FBS), hematocrit and obesity, were measured. The data on age, occupation, and smoking were collected. Air-conduction hearing threshold in smoker was significantly higher than non-smoker in categories of 250, 500, 1000 and 4000 Hz(p<0.05). Mean values of PTA-low, PTA-mid, and PTA-high in smoker were also significantly higher than non-smoker(p<0.05). In multiple regression analysis, smoking is likely to play a significant role after controlling age, occupation, DBP, FBS, total cholesterol, hematocrit, and obesity,(p<0.05). The hearing threshold was significantly increased with increasing age(p<0.05), the manufacturing worker may have higher hearing threshold(p<0.05). The higher hematocrit and the more obese, the higher hearing threshold(p<0.05). However, DBP, total cholesterol and FBS were not significantly related with hearing threshold level. In conclusion, smoking was significantly related with the hearing threshold level in adult men.; Summary

Association between air conduction hearing threshold and blood viscosity in normal adult males.: Sang Woo Kim, Jong Young Lee, Wan Seup Park, Kuck Hyeun Woo; Korean J Prev Med. 1997;30(3):623-629.

Abstract PDF: This is cross-sectional study a potential relationship between air conduction hearing threshold and blood viscosity in normal adult males(n=1677). We measure hearing threshold in frequency level at 500, 1000, 2000, 4000Hz by pure-tone audiometry and RBC profiles contains red cell number, hemoglobin, hematocrit. Blood viscosity replaced by hematocrit that are one major factor of influencing blood viscosity. PTAs(pure-tone averages) measured by hearing threshold averages level at 500Hz, 1000Hz, 2000Hz by pure-tone audiometry. Grades of PTAs(pure-tone averages) are less then 10.0dB group, between 10.0-19.9dB group and excess 20.0dB. The results are significantly association among hematocrit, red cell number and hearing loss(age adjust by ANACOVA).; Summary
