As a widespread toxic metal, arsenic had potential effect for hypertensive. We evaluated the association between urinary arsenic and the incidence of hypertension in adult residents along the Yangtze River of China.
We conducted the study of 1358 adults 18 to 74 years of age from Chizhou, Maanshan, and Tongling of Anhui province, who participated in the baseline study in 2014 to 2015. Inductively coupled plasma optical emission spectrometry was used to measure urinary as of residents, and follow-up extended through 2016 to 2017.
We identified 275 hypertension events. The hazard ratios (HRs) of highest quartile arsenic compared with lowest quartile was 1.49 for hypertension events (95% confidence interval [CI] = 1.05 to 2.12), and HRs (≥P 20 vs <P 20) was 1.37 (95% CI = 1.02 to 1.84).
Higher level of arsenic exposure might play a role in increasing the incidence of hypertension.

Clinical Significance: To control the blood pressure in the normal range, the hypertensive living in areas with higher levels of arsenic not only take antihypertensive medication, but also reduce the consumption of food contaminated with arsenic. And the regulation on minimizing the exposure to arsenic may be considered in policies of environmental health and intervention programs.
