Patient characteristics and frequency of bodily distress syndrome in primary care: a cross-sectional study

BackgroundBodily distress syndrome (BDS) is a newly proposed diagnosis of medically unexplained symptoms, which is based on empirical research in primary care.AimTo estimate the frequency of BDS in primary care and describe the characteristics of patients with BDS.MethodData were obtained from GP one-page registration forms, patient questionnaires (including a checklist for BDS), and national registers.ResultsA total of 1356 primary care patients were included, of whom 230 patients (17.0%, 95% confidence intervals CI] = 15.0 to 19.1) fulfilled the BDS criteria. BDS was more common among primary care patients aged 41–65 years (odds ratio OR] = 1.9, 95% CI = 1.3 to 3.0) and was equally frequent among males and females (female sex, OR 0.9, 95% CI = 0.6 to 1.3). Patients with BDS were characterised by poor health-related quality of life (HRQOL) on the 12-item Short-Form Health Survey, that is, physical component summary scores <40 (OR 20.5, 95% CI = 12.9 to 32.4) and mental component summary scores <40 (OR 3.5, 95% CI = 2.2 to 5.6). Furthermore, patients with BDS were more likely to have high scores on the Symptom Checklist for anxiety (OR 2.2, 95% CI = 1.4 to 3.4) and depression (OR 5.1, 95% CI = 3.3 to 7.9), but regression analyses showed that mental morbidity did not account for the poor HRQOL.ConclusionBDS is common among primary care patients, and patients with BDS have a higher probability of poor HRQOL and mental health problems.
