: Excess weight in women with fibromyalgia syndrome (FMS) may further contribute to joint pain and fatigue. However, there is little research addressing weight issues in this population.
: This study examined the relationship of body mass index (BMI) to quality of life.
: Quality of life was measured by the 36-Item Short Form Health Survey, severity of FMS, nutritional intake, Barriers to Health Promoting Behaviors for Disabled Persons Scale (BS), and self-efficacy for health-promoting behaviors (Self-Rated Abilities for Health Practices Scale) in women with FMS. Baseline data were collected on 179 women diagnosed with FMS.
: Controlling for age, BMI was significantly (p < .05) correlated with 36-Item Short Form Health Survey subscales of physical functioning, bodily pain and vitality, severity of FMS using the Tender Point Index, calories, protein, fat, saturated fat, BS, and Self-Rated Abilities for Health Practices Scale subscale for exercise. The findings support a growing body of evidence that excess weight is negatively related to quality of life and pain in women with FMS.

ABSTRACT: The purpose of this study is to determine whether there are some differences in the treatment responses to a multidisciplinary fibromyalgia (FM) treatment related with the baseline body mass index (BMI) of the participants. Inclusion criteria consisted of female sex, a diagnosis of FM (American College of Rheumatology criteria), age between 18 and 60 years, and between 3 and 8 years of schooling. Baseline BMI was determined, and patients were randomly assigned to one of the two treatment conditions: conventional pharmacologic treatment or multidisciplinary treatment. Outcome measures were pain intensity, functionality, catastrophizing, psychological distress, health-related quality of life, and sleep disturbances. One hundred thirty patients participated in the study. No statistical significant differences regarding pre-treatment outcomes were found among the different BMI subgroups, and between the two experimental conditions for each BMI category. General linear model analysis showed a significant interaction group treatment × time in pain intensity (p < .01), functionality (p < .0001), catastrophizing (p < .01), psychological distress (p < .0001), sleep index problems (p < .0001), and health-related quality of life (p < .05). No significant interactions were found in BMI × time, and in BMI × group treatment × time. There are not differences among normal weight, overweight and obese patients with FM regarding their response to a multidisciplinary treatment programme for FM which combines pharmacological treatment, education, physical therapy and cognitive behavioural therapy.

Although previous studies report associations between increased body mass index (BMI) and fibromyalgia symptoms, there is uncertainty whether this relationship is driven by physical factors, psychological factors, or both.
To assess these relationships in a clinical sample of patients with fibromyalgia.
Tertiary care facility
686 patients from an existing national fibromyalgia registry.
Patients completed a demographic form and self-report questionnaires including the Fibromyalgia Impact Questionnaire-Revised (FIQ-R), the Medical Outcomes Study Short Form-36 (SF-36), Brief Pain Inventory (BPI), and the 30-item Profile of Mood States (30-item POMS).
Main Outcome Measurements
FIQ-R overall impact subscale
BMI was significantly correlated with fibromyalgia impact (p<.001). The relationship between BMI and fibromyalgia impact was almost fully accounted for by physical factors and not psychological factors.
Despite patient report that pain hinders physical activity, clinicians who encounter patients with fibromyalgia, particularly patients with increased BMI, should be cognizant to invest time and resources to counsel patients on physical factors (i.e. physical activity) that could improve the patient’s symptom experience.
