Elevated homocysteine and hypertension in Xinjiiang Province, China.

Results: Hcy levels of Kazak in no hypertension and hypertension patients were highest (11.969.8 vs 19.0611.8 umol/L, respectively, unadjusted P5.004, adjusted P5.016). This pattern of higher Hcy values in hypertension patients was consistent across all ethnic groups even after adjustment (all P,0.05). The hypertension risks in the elevated Hcy (.13.9 umol/L) was 3.5 (95% CI, 2.2–5.4) times the normal Hcy (#13.9 umol/L) (P,0.001). Even after adjustment for potential confounders, this difference remained 3.1 times higher (95% CI, 1.9–4.8) (P,.001). Bivariate correlation analysis revealed a statistically significant relationship of Hcy with systolic or diastolic blood pressure across all ethnic groups.
