Abstract:
Objective:To investigate the relationship between individual arsenic exposure and hypertension of Tibetan residents in Nyingchi City, Tibet Autonomous Region (referred to as Tibet).Methods:From June to August 2023, Tibetan residents aged 18 to 78 years who had resided in Bomi County and Chayu County of Nyingchi City, Tibet for at least 10 years were selected as the study subjects by cluster sampling. Questionnaire survey, physical examination, and biochemical index testing were conducted on the study subjects. Meanwhile, hair samples were collected to determine the arsenic content. Binary logistic regression was used to analyze the influencing factors of hypertension.Results:A total of 447 Tibetan residents were included, with a hair arsenic content of (1.24 ± 0.02) mg/kg, including 155 hypertensive patients (34.68%). There were statistically significant differences in age, blood oxygen saturation, neck circumference, waist hip ratio, hemoglobin, hair arsenic, blood glucose, uric acid, and smoking status between the hypertension and normal blood pressure groups ( P < 0.05). The results of binary logistic regression analysis showed that age ( OR = 1.05, 95% CI: 1.03 - 1.07), uric acid ( OR = 1.00, 95% CI: 1.00 - 1.01), hair arsenic ( OR = 1.75, 95% CI: 1.07 - 2.84), and smoking ( OR = 2.22, 95% CI: 1.05 - 4.69) were risk factors for hypertension. Conclusion:The hair arsenic content is a risk factor for hypertension of Tibetan residents in Nyingchi City, Tibet.
