Relationship of Depression Scores and Ranges in Women Who Suffer From Fibromyalgia by Age Distribution: A Case-Control Study

Abstract

Background: Fibromyalgia may be defined as a chronic widespread pain condition that generates a functional impairment with various symptoms, such as depression.

Purpose: The main aim of this research was to compare the Beck Depression Inventory (BDI) scores and depression ranges in women who suffered from fibromyalgia with respect to healthy controls, overall and by age distributions.

Methods: A case-control observational study was performed. Two hundred women with a mean age of 58.61 ± 15.65 years old were recruited. The women were divided into case (women with fibromyalgia) and control (healthy women) groups. The BDI scores and depression ranges were collected.

Results: The depression ranges and BDI scores mean ± SD showed statistically significant differences (p < .001) between participants with fibromyalgia (19.30 ± 11.21 points; moderate depression) and healthy controls (6.37 ± 5.35 points; no depression). Regarding the age distributions, statistically significant differences were shown between fibromyalgia and control groups for adults (p < .001; 19.06 ± 6.55 vs. 4.69 ± 4.48 points) and older adults (p = .001; 20.25 ± 13.79 vs. 7.63 ± 5.47 points), respectively. ANOVA of the BDI scores with two factors and interaction (fibromyalgia presence and age distribution) determined no interaction between the two factors (p = .534) and statistically significant differences of BDI scores for fibromyalgia presence (p < .001; R² = 35.50%), but not for age distribution (p = .144).

Linking evidence to action: Measurable differences in higher BDI scores and depression ranges were shown in women who suffered from fibromyalgia with respect to healthy controls, regardless of age distribution. Greater probabilities (odds ratio = 15.88) of suffering from some level of depression (according to BDI scores) were found in women with fibromyalgia in comparison with healthy women. Although these findings did not seem to be influenced by age distribution, interventions targeting depression in practice, research, policy, management, or education must equally include adult and older adult women who suffer from fibromyalgia.
