Brief summary

The aim of the present study was to evaluate the association between ferritin levels and clinical parameters in patients with fibromyalgia syndrome.

Detailed description

This sectional study included 100 patients with non-anemic FMS diagnosis and 100 patients with non anemic non FMS diagnosis whose ferritin levels were measured within the last four weeks. The participants were evaluated using Fibromyalgia Impact Questionnaire (FIQ), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and Pittsburg Sleep Quality Index (PSQI) as well as with a questionnaire form about descriptive characteristics. Serum ferritin level of \<30 ng/mL was considered iron deficiency.

Design outcomes

Primary

MeasureTime frameDescription
Pitsburgh Sleep Quality Index1 yearPittsburgh Sleep Quality Index (PSQI) is an 18-item questionnaire measuring sleep quality and disorders in a time period of one month. PSQI measures subjective sleep quality, duration and latency of sleep, sleep disorders, habitual sleep efficiency, daytime dysfunction and use of medication for sleeping. PSQI distinguishes poor sleep from good sleep. minimum score 1 maximum score 9 ≥5 total points in PSQI mean poor sleep. \<5 total points in PSQI mean good sleep.

MeasureTime frameDescription
Fibromyalgia Impact Questionnarie Scores1 yearFibromyalgia Impact Questionnaire (FIQ) is a 10-item evaluation tool developed to measure status, prognosis and outcomes of FMS patients. Total points vary from 0 to 100. Higher points show the effect of FMS on functionality. mimimum score 0 maximum score 100 higher scores shows poor functionality.
Beck Depression Inventory1 yearBeck Depression Inventory (BDI) is a 21-item questionnaire evaluating the presence and severity of depression. Higher points mean heavier depression (0-9 points: minimum depression; 10-18 points: slight depression; 19-29 points: moderate depression; 30-63 points: severe depression). minimum 0 maximum 63 points higher scores mean worse outcome.
Beck Anxiety Inventory1 yearBeck Anxiety Inventory is a short, easily applied and graded, 21-item questionnaire to evaluate the severity of patients' anxiety. Total points vary from 0 to 63 (0-9 points: normal; 10-18 points: slight to moderate anxiety; 19-29 points: moderate to severe anxiety and 30-63 points: very severe anxiety). minimum 0 maximum 63 points higher scores mean worse outcome
