Factors associated with hyperhomocysteinemia in relatively healthy Taiwanese adults: A retrospective medical record study

Elevated homocysteine levels have been proposed as a risk factor for cardiovascular disease. The aim of this study was to evaluate factors associated with hyperhomocysteinemia in relatively healthy Taiwanese adults.A retrospective cross-sectional study was conducted using data from the health examination database in a medical center located in southern Taiwan. Hyperhomocysteinemia was defined as a plasma homocysteinemia level >15 μmol/L. Factors associated with hyperhomocysteinemia were evaluated using univariate and multiple stepwise logistic regression analyses.A total of 817 adults with a mean age of 55.5 years were included in the present study, and of them, 67 (8.2%) had hyperhomocysteinemia. Results from multiple logistic regression analysis showed that male sex (Odd ratio OR] = 12.28, 95% CI = 2.94–51.27, P = .001), advanced age (OR = 1.37 per 10 years, 95% CI = 1.06–1.77, P = .017), triglycerides (OR = 1.02 per 10 mg/dL, 95% CI = 1.01–1.04, P = .010), and uric acid (OR = 1.27, 95% CI = 1.09–1.49, P = .004) were significantly and independently associated with hyperhomocysteinemia.In this retrospective medical record study, male sex, advanced age, higher plasma level of triglyceride, and uric acid were significantly associated with hyperhomocysteinemia in relatively healthy Taiwanese adults.
