Background Fibromyalgia isa chronic pain syndrome of unknown etiology associated to emotional disorders and low levels in health related quality of life.
Objectives To compare socio-demographic variables, psychiatric comorbidity, and pain among fibromyalgia patients and a healthy control group.
Methods Observational quantitative research through the collection of socio-demographic data, psychiatric disorders (Structured Clinical Interview DSM-IV – SCID) and pain (Visual Analogue Scale – VAS). In 100 patients in the rheumatology outpatient clinic of the Universidade Federalde São Paulo (UNIFESP) and 50 people without a diagnosis of fibromyalgia in São Paulo were recruited.
Results Results have shown that fibromyalgia patients present ahigher frequency of psychiatric comorbidity, a lower rate ofcollege graduates, and more difficultyin performing professional activities compared to the healthy group. In terms of working status, there is a higher prevalence of unemployment, sick-leave, and precarious employment among fibromyalgia patients. The contributionto the household budget between patients and healthy individuals is 42% - 58%.In 14% of patients have their own income compared to 34% of healthy group.SCID have revealed that the most prevalent psychiatric disorders among fibromyalgia patients are: previous major depression (14%), current major depression (25%), consumption of alcohol (12%), panic associated to agoraphobia (9%), panic without agoraphobia (13%), agoraphobia (18%), hypochondria (13%), and bulimia (1%). Comparing fibromyalgia patientsand healthy individuals in terms of psychiatric comorbidity the following percentages must be noted:dysthymic mood (21% - 4%), social phobia (27% - 2%), specific phobia (42% - 9%), obsessive compulsive disorder (57% -11%), generalized anxiety disorder (76% -17%), somatization (72%>6%), and binge eats (10% - 6%). In 94% of patients have mild, moderate, or severe social – occupational difficulties; 26% of healthy individuals do not present this kind of difficulty,and the remaining report minimal difficulties which do not interferewith daily activities. In fibromyalgia patients thetimeof illnessranges between 5 to10 years. VAS has shown that patients have a high rate of pain,given that 61% of them have scores above 6 cm (on a scale of 0 to 10 cm) and 15% report 10 cm.
Conclusions Fibromyalgiapatients have more psychiatric disorders and worst socio-demographic indicators compared to healthy individuals.
