A6373 Prevalence and risk factors of H-type hypertension in Qinghai-Tibet plateau

Objectives: To investigate the prevalence and risk factors of hypertension combined with hyperhomocysteinemia (H-type hypertension) in Qinghai-Tibet Plateau, China. Methods: A total of 2058 hypertension patients who were hospitalized in Qinghai Cardio-Cerebrovescular Hospital from Feb 2014 to Dec 2016 were enrolled in this study. physical examination and laboratory examination were done for everyone. The risk factors of H-type hypertension was analyzed. Results: There were 1605 cases of H-type hypertension among the 2058 patients,which accounting for 78% of total hypertension patients. The average level of Hcy was 21.8 ± 10.2umol/L, which was higher than that in plain areas. Logistics regression analysis showed that male (β = 1.226, P = 0.003), Tibetan (β = 1.756, P = 0.000), high altitude residence (β = 1.067, P = 0.017), smoking (β = 1.565, P = 0.000) and too little vegetable intake (β = 0.884, P = 0.033) were risk factors of H-type hypertension. Conclusion: There was a greater incidence of H-hypertension in Qinghai-Tibet Plateau. Targeted prevention and treatment measures should be made for people accompanied by risk factors.
