Raynaud's disease:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Although the cause is unknown, several theories account for the reduced digital blood flow: intrinsic vascular wall hyperactivity to cold, increased vasomotor tone due to sympathetic stimulation, and antigen-antibody immune response (the most likely theory because abnormal immunologic test results accompany Raynaud’s phenomenon). Risk factors include associated diseases (Buerger’s disease, atherosclerosis, rheumatoid arthritis, scleroderma, and SLE) and smoking.
This disorder affects females more often than males.

About prevalence and incidence statistics:
The term 'prevalence' of Raynaud's phenomenon usually refers to the estimated population
of people who are managing Raynaud's phenomenon at any given time.
The term 'incidence' of Raynaud's phenomenon refers to the annual diagnosis rate,
or the number of new cases of Raynaud's phenomenon diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
