Somatization in the population: from mild bodily misperceptions to disabling symptoms

Area of Science:

• Psychiatry and Psychology
• Epidemiology
• General Medicine

Background:

• Somatization, the experience of physical symptoms without clear medical explanation, is often viewed along a continuum of severity.
• Understanding the population prevalence of somatization, from mild to severe forms, is crucial for public health and clinical practice.

Purpose of the Study:

• To investigate the prevalence of current somatization in the general population, considering varying levels of symptom severity.
• To identify demographic and epidemiological correlates associated with somatization across its spectrum.

Main Methods:

• A representative sample of 2,552 individuals in Germany was surveyed.
• A screening instrument assessed medically unexplained physical complaints occurring within the past 7 days.
• All 53 symptoms categorized under somatoform disorders in ICD-10/DSM-IV were included in the assessment.

Main Results:

• 81.6% of the sample reported at least one symptom with mild impairment, while 22.1% experienced symptoms with severe impairment.
• The average individual reported 6.6 symptoms associated with at least mild distress.
• Somatization was more prevalent in females, individuals over 45, those with lower education and income, and residents of rural areas. Common symptoms included pain (back, head, joints, extremities), food intolerance, and sexual dysfunction.

Conclusions:

• Medically unexplained complaints are a frequent occurrence in the general population.
• Approximately 75% of cases exhibit low levels of impairment and may not meet clinical significance criteria.
• Epidemiological factors associated with somatization are consistent across both clinical and non-clinical presentations.
