【摘要】：目的探讨铅作业工人体内血铅水平与膳食营养素的关系。方法以福建省南平市某蓄电池厂427名铅作业工人为调查对象,采用自行设计问卷调查作业工人工龄、接铅方式和膳食情况,测定其血铅水平。结果铅作业工人血铅水平中位数为340.1μg/L,血铅水平超标率为45.9%(196/427)。铁摄入过量的铅作业工人血铅超标率高于铁摄入适宜的铅作业工人(P0.012 5);维生素B2摄入过量的铅作业工人血铅超标率高于维生素B2摄入适宜的铅作业工人(P0.012 5)。Logistic回归分析结果显示:蛋白质摄入过量的铅作业工人发生血铅超标的风险低于蛋白质摄入适宜者(P0.01),硒摄入不足的铅作业工人发生血铅超标的风险低于硒摄入适宜者(P0.01);男性铅作业工人发生血铅超标的风险高于女性(P0.01),工龄越长的铅作业工人发生血铅超标的风险越高(P0.01),单纯接触铅尘的铅作业工人发生血铅超标的风险高于接触混合铅者(P0.01),能量摄入不足或过量的铅作业工人发生血铅超标的风险高于能量摄入适宜者(P0.01)。结论应建立膳食平衡、健康促进和工作环境控制的复合式干预模式。平衡铅作业工人膳食营养,增加能量和维生素B2的摄入。
[Abstract]:Objective to study the relationship between blood lead level and dietary nutrients in workers exposed to lead. Methods 427 lead-exposed workers in a storage battery factory in Nanping, Fujian Province were investigated. The working age, lead exposure and diet of workers were investigated by self-designed questionnaire survey, and their blood lead levels were measured. Results the median of blood lead level in workers exposed to lead was 340.1 渭 g / L, and the excess rate of blood lead level was 45.9%. The lead excess rate of lead exposed workers with excessive iron intake was higher than that of lead workers with proper iron intake, while the lead excess rate of lead exposed workers with excessive vitamin B2 intake was higher than that of lead workers exposed to vitamin B2 intake with P0.012 5).Logistic regression. The results showed that the risk of blood lead exceeding in workers exposed to excessive protein intake was lower than that of those with suitable protein intake (P 0.01), and that of lead workers with insufficient selenium intake was lower than that of those exposed to selenium. The risk of excessive blood lead in workers exposed to lead was higher than that of female workers. The risk of blood lead exceeding was higher in workers exposed to lead than in women. The higher the risk of excessive blood lead in workers exposed to lead dust was, the higher the risk of exposure to lead dust was compared with that of exposed workers exposed to lead dust. The risk of blood lead excess in workers exposed to insufficient or excessive energy intake was higher than that in those with suitable energy intake. Conclusion the compound intervention model of dietary balance, health promotion and working environment control should be established. Balance lead exposure to dietary nutrition, increase energy and vitamin B 2 intake.
