To explore the causal relationship between serum micronutrients and hypertension using Mendelian randomization, thereby promoting the prevention and health management of hypertension.
Fourteen serum micronutrients were selected as exposure factors, with hypertension as the outcome. Two-sample Mendelian randomization analyses were conducted based on genome-wide association study data from European populations, followed by multivariable Mendelian randomization analyses to identify variables that may have a causal relationship with the outcome, determining the independent effects of each exposure factor on the outcome.
Univariate Mendelian randomization analysis indicated a positive causal effect of elevated copper levels on the incidence of hypertension (P<0.05). Multivariable Mendelian randomization showed that the causal relationship between copper and hypertension remained significant after controlling for potassium and vitamin B6 (OR=1.028, 95%CI: 1.009-1.047, P<0.05).
There is a causal relationship between elevated copper levels and hypertension. However, the findings of this study require validation through randomized controlled trials.
