在美国营养健康抽查中,对有代表性1240位妇女(年龄16岁-49岁)做了横断面调查,发现血汞水平与血压值有相关关系。在多元模型中,整体人群的血汞水平与血压无相关关系。但依据是否摄入鱼类(假定n-3系列的长链脂肪酸摄入可以降低血压水平),对数据进行分层,分为759位摄入鱼类者和481位非摄入鱼类者。发现在非摄入鱼类者中,血汞水平增加1.3mg/L(四分位间距),收缩压就显著的增加0.244 kPa(95%CI:0.36,3.30)。同样舒张压与血汞水平也有相似的关系,但无统计学意义。在整体人群中未发现本底水平的汞暴露对血压有负面影响,但在非摄入鱼类者中的年轻和中年妇女本底汞暴露与血压有负相关。
A cross-sectional survey of 1,240 representative women (aged 16-49) conducted in the US Nutritional Health Check found a correlation between blood mercury levels and blood pressure. In the multivariate model, there was no association between blood mercury levels and overall blood mercury levels in the general population. However, the data were stratified into 759 fish intake and 481 non-fish intake, depending on whether fish were taken (assuming that n-3 series long-chain fatty acid intake reduced blood pressure). A significant increase of 0.244 kPa (95% CI: 0.36, 3.30) in systolic blood pressure was found with a 1.3 mg / L increase in blood mercury levels in non-ingested fish. The same diastolic blood pressure and blood mercury levels also have a similar relationship, but no statistically significant. No background-level mercury exposure was found to have a negative effect on blood pressure in the general population, but background mercury exposure in young and middle-aged women with non-fish intake was negatively correlated with blood pressure.
