Overview

Risk factors for development of Hemophilia A and B include being of male sex and having a positive family history of the disease.

It is of note that acquired forms of the disease occur in specific circumstances including Malignancies, Pregnancy, Autoimmune disorders, Certain medications; All of which could be considered as Hemophilia risk factor either. 

Risk Factors

Common risk factors in the development of Hemophilia A are:

Best-studied risk factors of the acquired form of the disease include:[2][3][4]

Of note, the majority of reported acquired cases of Hemophilia are about Hemophilia A type. It appears that, the same as hereditary form, acquired form of Hemophilia B is rarer than Hemophilia A too.

The remaining cases of acquired Hemophilia are idiopathic or the underlying etiology is not known yet.
