Risk factors for primary Raynaud's include:

  • Your gender. Primary Raynaud's affects women more than men.
  • Your age. Although anyone can develop the condition, primary Raynaud's often begins between the ages of 15 and 30.
  • Where you live. The disorder is also more common in people who live in colder climates.
  • Your family history. Additionally, a family history appears to increase your risk of primary Raynaud's. About one-third of people with primary Raynaud's have a first-degree relative — a parent, sibling or child — with the disorder.

Risk factors for secondary Raynaud's include:

  • Associated diseases. These include conditions such as scleroderma and lupus.
  • Certain occupations. People in occupations that cause repetitive trauma, such as workers who operate tools that vibrate, also may be more vulnerable to secondary Raynaud's.
  • Exposure to certain substances. Smoking, medications that affect the blood vessels and exposure to chemicals such as vinyl chloride are associated with an increased risk of Raynaud's.
