Key result
Atherogenic risk factors, including smoking, high BMI, high triglycerides, and low HDL, were associated with increased low-frequency hearing thresholds.
Why the study?
Do atherogenic risk factors increase hearing thresholds in white- and blue-collar workers?
Cross-Sectional (n=576)
Do atherogenic risk factors increase hearing thresholds in white- and blue-collar workers?
Atherogenic risk factors, including smoking, high BMI, and dyslipidemia, are associated with worse low-frequency hearing thresholds.

Association in cross-sectional data does not support practice change; leaves open causal effects on hearing.
The objective of this study was to evaluate the influence of atherogenic risk factors on hearing thresholds. In a cross-sectional study we analyzed data from a Danish survey in 2009-2010 on physical and psychological working conditions. The study included 576 white- and blue-collar workers from children's day care units, financial services and 10 manufacturing trades. Associations between atherogenic risk factors (blood lipids, glycosylated hemoglobin, smoking habits, body mass index (BMI), and ambulatory blood pressure) and hearing thresholds were analyzed using multiple linear regression models. Adjusted results suggested associations between smoking, high BMI and triglyceride level and low high-density lipoprotein level and increased low-frequency hearing thresholds (average of pure-tone hearing thresholds at 0.25, 0.5 and 1 kHz). Furthermore, an increasing load of atherogenic risk factors seemed associated with increased low-frequency hearing thresholds, but only at a borderline level of statistical significance. Associations were generally strongest with hearing levels of the worst hearing ear. We found no statistically significant associations between atherogenic risk factors and high-frequency hearing thresholds (average of pure-tone hearing thresholds at 4, 6 and 8 kHz).

Frederiksen et al. (2014) reported a cross-sectional. Atherogenic risk factors (blood lipids, glycosylated hemoglobin, smoking, BMI, blood pressure) was evaluated on Hearing thresholds (low-frequency and high-frequency). Atherogenic risk factors, including smoking, high BMI, high triglycerides, and low HDL, were associated with increased low-frequency hearing thresholds.
