摘要

目的:本研究探讨尿液中重金属和桥本甲状腺炎(hashimoto's thyroiditis,HT)之间的潜在关系,为正常人群和HT人群的重金属暴露的预防和控制提供依据.方法:基于2007-2012年美国国家健康和营养调查(NHANES)数据库,纳入5 011例同时具有尿重金属(镉、钴、钡、铅、铀)浓度指标和甲状腺过氧物酶抗体(TPOAb)或甲状腺球蛋白抗体(TgAb)数据的人群.采用逻辑回归模型探讨尿液中重金属与HT的关系,运用限制立方样条模型检查可能的非线性关联,将不同浓度的镉、钴、钡与HT的剂量-反应关系可视化,同时针对性别进行亚组分析.结果:HT患者的尿镉浓度(0.27 μg/L)显著高于正常人群(0.24 μg/L),其余几种重金属浓度在HT分布中无统计学差异(P>0.05).多因素Logistic回归显示,尿镉每上升一个四分位数,HT的患病风险增加23.7％(OR=1.237,95％CI:1.083～1.414);尿钴每上升一个四分位数,HT的患病风险增加9.7％(OR=1.097,95％CI:1.021～1.177);与尿钡浓度最低组(Q1)相比,尿钡浓度最高组(Q4)HT的患病风险降低48％(OR=0.520,95％CI:0.295～0.916).但限制性三次样条回归结果显示三者与HT的患病率均无剂量反应关系.结论:重金属(镉、钴、钡)暴露与HT有关.镉、钴可能是HT的危险因素,钡可能是HT的保护因素,镉、钴与女性患病相关性显著,为制定干预措施和健康促进指导提供证据,提高人们对重金属暴露的关注度.

Abstract

Objective This study aimed to expore the potential relationship between heavy metals in urine and Hashimoto's thyroiditis(HT),providing a basis for the prevention and control of heavy metal exposure in the general population and in those with HT.Methods Data included 5 011 cases with both urinary heavy metals(cadmium,cobalt,barium,lead,uranium)con-centration indexes and thyroid peroxidase antibody(TPOAb)or thyroglobulin antibody(TgAb)from the 2007-2012 National Health and Nutrition Examination Survey(NHANES)(2007-2012).Logistic regression models were used to explore the re-lationship between heavy metals in urine and HT,and restricted cubic spline models were used to examine possible nonlinear associations and to use restricted cubic spline models to visualize the dose-response relationship between different concentra-tions of cadmium,cobalt,and barium and HT.Furthermore,subgroup analyses were performed for gender.Results The urinary cadmium concentration in HT patinets(0.27 μg/L)was significantly higher than that in the normal population(0.24 μg/L),while the concentrations of the other heavy metals showed no statistical difference in HT distribution.Multifactorial logistic re-gression showed that the risk of HT increased by 23.7%for each quartile increase in urinary cadmium(OR=1.237,95%CI 1.083-1.414),and by 9.7%for each quartile increase in urinary cobalt(OR=1.097,95%CI 1.021-1.177).Compared to the group with the lowest urinary barium concentration(Q1),the group with the highest urinary barium concentration(Q4)had a 48%reduction of the risk of HT(OR=0.520,95%CI 0.295-0.916).However,the results of restricted cubic spline regres-sion showed no dose-response relationship between the three and the prevalence of HT.Conclusion Exposure to heavy metals(cadmium,cobalt,barium)is associated with HT.Cadmium and cobalt may serve as potential risk factors for HT,while barium may have a protective effect against the disease.Cadmium and cobalt may be more pronounced in women.This provides the evidence for the development of intervention and health promotion guidelines,raising awareness of heavy metal exposure.
