• Chronic Fatigue Syndrome Risk Factors

Risk Factors

Research is ongoing to explore the possible causes and risk factors for CFS. There are some characteristics that indicate individuals at greater risk for developing CFS:

  • CFS occurs four times more frequently in women than in men, although people of either sex can develop the disease
  • CFS occurs most often in people in their 40s and 50s, but people of all ages can get CFS
  • CFS is less common in children than in adults
  • CFS is more common in adolescents than in younger children
  • CFS occurs in all ethnic and racial groups and in all the countries of the world
  • CFS affects people of all socioeconomic strata
  • CFS is sometimes seen in members of the same family, but that does not indicate that it is contagious. However, there may be a familial or genetic link.
  • CFS affects people who are overweight and inactive.
  • Chronic unresolved stress also predisposes an individual to CFS.
