目的通过比较职业性噪声暴露人群与非职业性噪声暴露人群的血脂各项指标之间的差异,探索噪声对血脂的影响规律,为预防和减轻噪声作业对工人的影响提供科学依据。方法通过检测血脂中总胆固醇(CHO)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)指标的含量水平进行横断面研究,比较职业性噪声暴露人群与非职业性噪声暴露人群的血脂各指标差异。结果血脂异常检出率观察组为51.18%,对照组为43.38%,差异有统计学意义(χ2=5.674,P<0.05);噪声观察组工人血脂成分中TG、CHO、LDL-C含量与对照组比较明显提高,HDL-C含量较对照组低,差异均有统计学意义(P<0.01);随着工龄的增加,TG、CHO、LDL-C含量也增高,各工龄之间,TG、CHO、LDL-C、HDL-C差异有统计学意义(P<0.01),工龄5~9年组和10年~组与对照组比较,差异有统计学意义(P<0.05)。结论长期噪声接触可使工人血脂代谢紊乱,应加强对噪声暴露人员的宣传教育与防治。
Objective To explore the influence of noise on blood lipids by comparing the differences of blood lipid among people exposed to occupational noise and those exposed to non-occupational noise, and to provide a scientific basis for preventing and mitigating the noise impact on workers. Methods The levels of total cholesterol (CHO), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) Difference of blood lipid among sex noise exposed and non-occupational noise exposed people. Results The detection rate of dyslipidemia was 51.18% in the observation group and 43.38% in the control group, the difference was statistically significant (χ2 = 5.674, P <0.05). The content of TG, CHO and LDL- The levels of HDL-C and HDL-C were significantly lower than those of the control group (P <0.01) CHO, LDL-C and HDL-C had statistical significance (P <0.01). There was significant difference between the 5-year-9 and 10-year-old groups and the control group (P <0.05). Conclusion Long-term noise exposure can disrupt blood lipid metabolism in workers, and publicity, education and prevention of noise exposure personnel should be strengthened.
