ABSTRACT
<p><b>OBJECTIVE</b>To study the relations of noise expose and hypertension in mechanic factory workers.</p><p><b>METHODS</b>A cross-sectional study on 1205 workers (exposed to different noise levels) in Hunan was carried out, using questionnaire, blood pressure of the workers and the exposure level to noise at workplace.</p><p><b>RESULTS</b>The prevalence of hypertension was 12.1% in mechanic factory workers. There was an increasing tendency of hypertension rate along with the increase of accumulative noise doses (tendency chi-squared = 29.932, P < 0.01). Result by logistic regression analysis after adjusting age, history of hypertension in parents and body weight index showed that the risk of hypertension increased about 5% by 1 dB(A) of more noise exposure (OR = 1.047).</p><p><b>CONCLUSION</b>Noise exposure might serve as a risk factor of hypertension. Reducing the sound pressure level in workshops could work as an effective measure to control the incidence rate of hypertension in mechanic factory workers.</p>

OBJECTIVE@#To determine the status and influence factors of hypertension on mechanic factory workers and to provide reference for further hypertension prevention and control.@*METHODS@#A cross-sectional study on 1205 workers (exposed to different noise levels) in Hunan was carried out by using questionaire and measuring the blood pressure of the workers and the noise exposure level in the workplace. The prevalence and the influence factors of hypertension among mechanic factory workers were analysed.@*RESULTS@#The hypertension prevalence was 12.1%. Logistic regression analysis showed the body weight index (BMI), age, and history of hypertension in parents and accumulative noise dose levels influenced the hypertension prevalence.@*CONCLUSION@#Controlling the body weight, reducing alcohol consumption, decreasing the sound pressure level in workshops and advocating healthy diet may reduce the prevalence rate of hypertension among mechanic factory workers.
