The Epidemiological Characteristics of High Serum Level of Homocysteine in Kazakh Population at Xinyuan County of Xinjiang / 中国循环杂志

ABSTRACT

Objective: To observe the characteristics of serum homocysteine (Hcy) distribution and the epidemiological characteristics of high serum level of Hcy (HHcy) in Kazakh population. Methods: The stratiifed cluster random sampling method was used to investigate 1003 kazakh individuals in Xinyuan county of Xinjiang including 433 male and 570 female, and they were individuals into 5 age groups①(25-34) years, n=333,②(35-44) years, n=306, ③(45-54) years, n=230, ④(55-65) years, n=90, ⑤>65 years, n=44. The questionnaire survey, physical check-up and blood biochemical examination were performed and compared among different groups. Results: ① The geometrical mean of Hcy was 13.3μmol/L, and the male was higher than female as 16.0μmol/L vs 11.6μmol/L. ②By age stratiifcation, the serum levels of Hcy elevated with the increased age accordingly. Except for those with the age>65 years, the serum levels of Hcy were all higher in male than female in other 4 age groups. ③The average rate of HHcy prevalence was 31.5%, and the male was higher than female as 49.9%vs 17.5%.④The average rate of H type hypertension prevalence was 35.1%, and the male was higher than female as 44.3%vs 28.1%. There were 87.6%of H type hypertensive patients with H type hypertension, and the male was higher than female as 95.0%vs 80.0%, all P Conclusion: The serum levels of Hcy were different from gender and age; the prevalences of HHcy and H type hypertension were higher in Kazakh population at Xinyuan county of Xinjiang. Community intervention should be conducted to improve the public health condition in Kazakh population.
