Objective: To provide the basis of prevention and control risk of virus transfusion, this study discusses the status quo of voluntary blood donation in Urumqi. Furthermore, the detected results of voluntary blood donors and their influential factors are analyzed. Methods: To collect the statistical data of Urumqi's blood donors in January and May from 2004 to 2008, which including demographic characteristics and five detected results of voluntary blood donors. Multivariable logistic regression were employed to explore influential factors of the detected results; the dependent variable was detected results; the independent variables were gender, age, nation, occupation, frequency of donating blood, et al. Results: Among the 26262 voluntary blood donors,the blood detected positive rate was 3.5% (917/26262). There were significant associations with the positive rate among year, sex, age, nation, education level, marriage and occupation. The positive rates of ATL, HBsAg, anti-HCV, anti-HIV and syphilis are 1.2%, 0.7%, 0.8%, 0.2% and 0.6% respectively. The positive rate of ATL was significantly associated with sex, age, education level, marriage and occupation, rather than nation; HBsAg with sex, age, education level and occupation, rather than marriage and nation; anti-HCV with age, education level and occupation, rather than sex, marriage and nation; anti-HIV only with sex; syphilis with age, education level, nation, marriage and occupation, rather than sex. The positive rates in 200ml, 300ml and 400ml voluntary blood donors were 3.9%, 3.1% and 3.0% respectively; in 1 time, 2 times and 3 or more times voluntary blood donors were 4.8%, 2.2% and 1.2% respectively, and they were all significant. Multivariable logistic regression revealed that: (i) The influential factors of detected results were sex, age, nation, education level, occupation, amount of donating blood, frequency of donating blood, and body mass index (BMI). (ii) The influential factors of ALT detected results were sex, age, occupation, amount of donating blood, frequency of donating blood, and body mass index. (iii) The influential factors of HBsAg detected results were sex, age, occupation and frequency of donating blood. (iv) The influential factors of anti-HCV detected results were age, marriage, education level and frequency of donating blood. (v) The influential factors of anti-HIV detected results were sex and frequency of donating blood. (vi) The influential factors of syphilis detected results were age, nation, education level, occupation and frequency of donating blood. Conclusions: The blood detected positive rates of voluntary blood donors were significant different among sex, age, nation, education level, occupation and frequency of donating blood. The influential factors of detected results were sex, age, nation, education level, occupation, amount of donating blood, frequency of donating blood, body mass index and so on. The effective ways to ensure blood safety are to strengthen the propaganda of blood knowledge and transfusion transmitted diseases detection, advocate female, repeat blood donors and people with high education lever to donate blood.
