Suicidal ideation in patients with fibromyalgia: a cross-sectional study

Chronic pain, sleep disturbances, and depression, which are relevant symptoms of fibromyalgia syndrome, have been demonstrated to be associated with an increased likelihood of suicidal behaviors. Mortality from suicide has been shown to be greater among patients with fibromyalgia. This study aimed to assess the prevalence of suicidal ideation among a sample of patients with fibromyalgia and to evaluate its relationship with the clinical symptomatology of fibromyalgia. Baseline data from fibromyalgia patients willing to participate in different clinical studies were collected. Outcome measures included the Fibromyalgia Impact Questionnaire, the Beck Depression Inventory, the Pittsburgh Sleep Quality Index, the Brief Pain Inventory, and the SF-12 Health Survey. The scores for these scales were compared between patients with and without suicidal ideation. The presence of suicidal ideation was assessed using the answer provided to item 9 of the Beck Depression Inventory. The results were adjusted by age, sex, total comorbidity, and time since diagnosis with multiple linear regression. The sample comprised 373 patients of whom one hundred and seventy-nine (48%) reported suicidal ideation: 148 (39.7%) reported passive suicidal ideation and 31 (8.3%) active suicidal ideation. Suicidal ideation was markedly associated with depression, anxiety, sleep quality, and global mental health, whereas only weak relationships were observed between suicidal ideation and both pain and general physical health.
