Epidemiological status and risk factors of hypertension in very high altitude area of Naked in Tibet.

Objective To understand the epidemiological status of hypertension and related influencing factors in the areas of very high altitude in Tibet, and provide a basis for the prevention and control of hypertension in high altitude areas. Methods Using the whole-group random sampling method, questionnaires and physical examinations were conducted to collect basic personal information, height, weight, and blood pressure from adult Tibetan residents living in Jiaqiong Township, Bange County, Naked City, Tibet Autonomous Region. SPSS 26. 0 software was used for descriptive analysis, univariate analysis and Logistic regression analysis. Results The prevalence of hypertension among native adult Tibetan residents in Jiaqiong Town, Bange County, Naked City was 25. 4%, with 30. 5% in males and 21. 3% in females. The results of the multifactorial logistic regression analysis showed that the age group was middle-aged group (45 -59 years old) (OR = 3. 570, 95% CI = 2. 036-6.260, P <0. 001), elderly group (≤60 years old) (OR =6.213, 95% CI = 2. 744-14.067, P < 0. 001), obesity (OR = 3. 292,95% CI = 1. 721-6. 298, P < 0. 001), waist-to-height-ratio 0. 5 (OR =2. 733, 95% CI = 1. 278-5. 844, P < 0. 05 ) were the independent risk factors for hypertension. Female gender (OR = 0. 402,95 % CI =0. 237-0. 682, P = 0. 001) were protective factors for hypertension. Conclusion The prevalence of hypertension in native Tibetans living in the very high altitude areas of Tibet is at an average level, and people with advanced age, obesity, and waist-to-height ratio ≤0. 5 are at high risk of hypertension.
