The nature and correlates of hypochondriasis are still poorly understood, especially in settings other than those in North America and Western Europe.
A total of 25916 consecutive patients making ambulatory visits to primary care clinics at 15 sites in 14 countries were screened using the 12-item General Health Questionnaire (GHQ-12).
Based on the screen-score performance, a stratified sample of 5447 of respondents was evaluated at the second-stage (response rate : 62%). Evaluation consisted of physician-rated physical and psychological health status and self-ratings of overall health, physical disability and GHQ-28.
Interviewers conducted assessment of psychiatric status, using the Composite International Diagnostic Interview (CIDI) and occupational disability.
Across the sites, the occurrence of ICD-10 hypochondriasis was 0.8% (95% Confidence Interval, 0.5-1.0%) and over 1.5% at only two sites.
A less restrictively-defined form of the disorder had a pooled frequency of 2.2% (95% Confidence Interval, 1.8-2.6%) across the sites.
Patients with this abridged hypochondriasis were more likely than those without to have co-morbid major depression and generalized anxiety disorder.
They had a poorer perception of their health, were more physically disabled, were more impaired in the performance of occupational role, and were above-average utilizers of health service. (...)
