Abstract:

Objective To investigate the influence factors for the levels of serum homocysteine(Hcy) in middle-aged and elderly people in Dongjing community of Shanghai.Methods A total of 2 336 healthy subjects ≥55 years old were enrolled from Dongjing community. Their blood pressure,serum Hcy,blood lipid,glucose(Glu) and so on were determined. According to age,sex,systolic blood pressure,diastolic blood pressure and body mass index(BMI),they were classified into hypertension group and non-hypertension group,diabetes mellitus group and non-diabetes mellitus group,heart disease group and non-heart disease group,respectively. According to biochemical indices,results were classified into normal and abnormal groups. The levels of serum Hcy and the influence factors were evaluated. Results The prevalence rate of hyperhomocysteinemia in males(23.0%) was higher than that in females(8.1%,P<0.01). Serum Hcy levels increased with ages,while the prevalence rate of hyperhomocysteinemia had statistical significance(P<0.01). In different systolic blood pressure groups of <15.96,15.96-18.49 and ≥18.62 kPa,the prevalence rates of hyperhomocysteinemia were 11.5%,14.8% and 17.1% (P<0.05). The prevalence rates of hyperhomocysteinemia in heart disease and non-heart disease groups were 18.0% and 13.1%(P<0.01). The prevalence rates of hyperhomocysteinemia in abnormal creatinine(Cr),uric acid(UA) and urea groups (44.1%,24.6% and 24.2%) were higher than those in normal Cr,UA and urea groups(12.9%,12.3% and 14.2%,P<0.01). In abnormal total cholesterol(TC) group,the prevalence rate of hyperhomocysteinemia was lower than that in normal TC group(12.8% and 16.3%,P<0.05). The prevalence rates of hyperhomocysteinemia had no statistical significance in groups with normal and abnormal Glu,triglyceride(TG),BMI and systolic blood pressure,and there was no statistical significance for diabetes mellitus and hypertension or not(P>0.05). Bivariate logistic regression analysis showed that heart disease,male,UA,Cr and systolic blood pressure were influence factors for the levels of Hcy.Conclusions Male,heart disease,UA,Cr and systolic blood pressure are risk factors of hyperhomocysteinemia among middle-aged and elderly people.
