To investigate the prevalence and influencing factors of hyperhomocysteinemia among Tibetan residents in the west of Xizang Ali.
By using the method of multi-stage cluster random sampling, Tibetan residents were randomly selected from the western area of Xizang Ali for physical examination and questionnaire survey, and blood routine and biochemical indexes were collected. The prevalence and influencing factors of hyperhomocysteinemia in this area were analyzed by chi-square test and multivariate logistic regression.
A total of 1 362 Tibetan residents in the western region of Xizang Ali were investigated. The results showed that there were 1 044 patients with hyperhomocysteinemia, with a prevalence rate of 76.7%. The prevalence rate of males (84.8%) was higher than that of females (71.5%). Smoking (OR=1.988, 95%CI:1.076-3.675), poor household (OR=1.775, 95%CI: 1.204-2.540), hyperuricemia (OR=3.416, 95%CI: 2.494-4.679), hypercholesterolemia (OR=4.051, 95%CI: 2.811-5.838), and hypertriglyceridemia (OR=2.589, 95%CI: 1.765-3.798) were risk factors of hyperhomocysteinemia. Female (OR=0.538, 95%CI: 0.384-0.752) and agricultural and pastoral areas (OR=0.312, 95%CI:0.156-0.625) were protective factors.
The prevalence rate of hyperhomocysteinemia is high in the western region of Xizang Ali. Sex, residence, smoking, and poor households are the influencing factors of hyperhomocysteinemia. Hyperhomocysteinemia is significantly associated with hyperuricemia, hypercholesterolemia, hypertriglyceridemia, and other diseases.
