Supplemental Digital Content is available in the text. The association of blood pressure (BP) with manganese—an essential trace element required for human health—remains poorly studied. In 734 randomly recruited Swiss participants (mean age, 47.5 years; 51.4% women), we related ambulatory BP to 2 biomarkers, plasma manganese (pMn) and the urinary manganese (uMn) excretion. To allow for diurnal variation, we assessed BP and uMn over 24 hours and during wakefulness and sleep, using split urine samples. Twenty-four-hour, daytime, and nighttime systolic/diastolic BPs averaged 119.8/78.1, 123.8/81.2, and 107.0/68.3 mm Hg; the corresponding median uMn were 199.5, 83.0, and 51.5 μmol and median pMn, 0.52 μg/L. In analyses dichotomized by the median of the biomarkers, greater pMn was associated with higher 24-hour systolic/diastolic BP (+4.1/+2.3 mm Hg; P≤0.0003), greater daytime uMn with lower daytime BP (−3.5/−1.9 mm Hg; P≤0.0067), and greater nighttime uMn with higher nighttime BP (+2.9/+1.2 mm Hg; P≤0.046). In multivariable-adjusted analyses, significance (P≤0.030) was retained for the positive association of 24-hour and daytime diastolic BP with pMn and for systolic BP in relation to uMn at night. The association sizes for a 2-fold increment in the biomarkers amounting to 0.77 mm Hg (95% CI, 0.08–1.47 mm Hg), 0.97 (CI, 0.20–1.76) and 1.33 (CI, 0.20–2.50 mm Hg), respectively. In conclusion, there were positive associations between diastolic BP and pMn over 24 hours and during daytime and between systolic BP and uMn at night.

与血浆和尿锰相关的动态血压

补充数字内容在文本中可用。血压 (BP) 与锰(人类健康所需的一种必需微量元素)之间的关联仍然缺乏研究。在 734 名随机招募的瑞士参与者(平均年龄 47.5 岁;51.4% 女性)中,我们将动态血压与 2 个生物标志物、血浆锰 (pMn) 和尿锰 (uMn) 排泄联系起来。为了考虑到昼夜变化,我们使用分离的尿液样本评估了 24 小时内以及清醒和睡眠期间的 BP 和 uMn。24 小时、白天和夜间收缩压/舒张压平均为 119.8/78.1、123.8/81.2 和 107.0/68.3 mm Hg;相应的中值 uMn 分别为 199.5、83.0 和 51.5 μmol,中值 pMn 为 0.52 μg/L。在按生物标志物中位数划分的分析中,较高的 pMn 与较高的 24 小时收缩压/舒张压相关(+4.1/+2.3 mmHg;P≤0.0003),白天 uMn 较大,白天 BP 较低(-3.5/-1.9 毫米汞柱;P≤0.0067),夜间 uMn 较大,夜间 BP 较高(+2.9/+1.2 毫米汞柱;P≤0.046)。在多变量调整的分析中,24 小时和白天舒张压与 pMn 的正相关以及收缩压与夜间 uMn 的正相关性仍保持显着性(P≤0.030)。生物标志物增加 2 倍的关联大小分别为 0.77 毫米汞柱(95% CI,0.08-1.47 毫米汞柱)、0.97(CI,0.20-1.76)和 1.33(CI,0.20-2.50 毫米汞柱) . 总之,24 小时内和白天舒张压与 pMn 之间以及夜间收缩压与 uMn 之间存在正相关。在多变量调整分析中,24 小时和白天舒张压与 pMn 的正相关性以及收缩压与夜间 uMn 的正相关性仍保持显着性(P≤0.030)。生物标志物增加 2 倍的关联大小分别为 0.77 毫米汞柱(95% CI,0.08-1.47 毫米汞柱)、0.97(CI,0.20-1.76)和 1.33(CI,0.20-2.50 毫米汞柱) . 总之,24 小时内和白天舒张压与 pMn 之间以及夜间收缩压与 uMn 之间存在正相关。在多变量调整的分析中,24 小时和白天舒张压与 pMn 的正相关以及收缩压与夜间 uMn 的正相关性仍保持显着性(P≤0.030)。生物标志物增加 2 倍的关联大小分别为 0.77 毫米汞柱(95% CI,0.08-1.47 毫米汞柱)、0.97(CI,0.20-1.76)和 1.33(CI,0.20-2.50 毫米汞柱) . 总之,24 小时内和白天舒张压与 pMn 之间以及夜间收缩压与 uMn 之间存在正相关。0.20–2.50 毫米汞柱),分别。总之,24 小时内和白天舒张压与 pMn 之间以及夜间收缩压与 uMn 之间存在正相关。0.20–2.50 毫米汞柱),分别。总之,24 小时内和白天舒张压与 pMn 之间以及夜间收缩压与 uMn 之间存在正相关。
