title: ABO blood groups and risk of deep venous thromboembolism in Chinese Han population from Chaoshan region in South China.
abstract: Objectives: To demonstrate the prevalence of ABO blood groups with deep venous thromboembolism in Chinese Han population.
  
  
  METHODS
  A retrospective study was conducted between January 2010 and March 2015 in The First Affiliated Hospital of Shantou University Medical College in Chaoshan District of Guangdong Province in South China. Eighty nine patients with confirmed diagnosis of deep venous thromboembolism were included. Frequency of blood groups was determined. Results: Of 89 patients with deep venous thromboembolism, 28 patients had blood group A (31.5%), 28 patients had blood group B (31.5%), 13 patients had blood group AB (14.6%), and 20 patients had blood group O (22.5%). Compared with O blood type, the odds ratios of deep venous thromboembolism for A, B and AB were 2.23 (95% CI, 1.27-3.91), 2.34 (95% CI, 1.34-4.09) and  4.43 (95% CI, 2.24-8.76). Conclusion: There is a higher risk of venous thromboembolism in non-O blood groups than O group.
