To study the relations of noise expose and hypertension in mechanic factory workers.
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.
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).
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.
研究机械工厂工人噪声暴露与高血压的关系。
对湖南1205名（暴露于不同噪声水平）工人进行横断面研究，采用问卷调查、工人血压及工作场所噪声暴露水平等方法。
机械工厂工人高血压患病率为12.1%。高血压患病率随累积噪声剂量增加呈上升趋势（趋势卡方=29.932，P<0.01）。调整年龄、父母高血压病史和体重指数后进行逻辑回归分析结果显示，噪声暴露每增加1 dB(A)，高血压风险增加约5%（比值比=1.047）。
噪声暴露可能是高血压的危险因素。降低车间声压级可作为控制机械工厂工人高血压发病率的有效措施。
