title: Identifying somatization disorder in a population-based health examination survey: psychosocial burden and gender differences.
abstract: Despite its enormous medical burden, little is known about the epidemiology of somatization in the community. The present study screened a representative population-based survey of 7,466 subjects in the age range of 25 to 69 years for the occurrence of somatization. A total of 137 (1.84%) individuals experienced six or more symptoms from at least two different body sites without an identifiable organic cause. These patients exhibited a lower quality of life (P < or = 0.0001) and suffered from higher levels of emotional stress (P < or = 0.0001) than their counterparts in the healthy subsample (n=906). Somatization was not associated with a medical diagnosis, but disability days, the use of medical services, and the level of medication was higher in the somatization disorder group (P < or = 0.004). The somatization risk was only 1.6-fold higher for women in comparison to men but escalated for women rapidly to an approximately 4-fold risk when being female was combined with low social class and high emotional distress. Against expectation, the somatization risk for men also mounted 3-fold under the identical risk constellation.
