CFS tend to focus on the psychosocial and ignore other variables such
as weight gain as a side effect of many medications used to control
symptoms in such patients. As well role emotional scores could
possibly be related to cultural expectations regarding weight and
unrelated to fibromyalgia in this particular instance. Careful
interpretation and accounting for as many variables as possible makes
for better studies.

Abstract
Patients suffering from fibromyalgia (FM) had widespread
musculoskeletal pain and stiffness, fatigue, sleep disorders,
cognitive impairment and other symptoms, which seriously affects their
quality of life (QoL), making it difficult to perform normal
activities.
Moreover, FM has been associated with a higher prevalence of
overweight and obesity than in the general population.
Weight reduction has been beneficial in both FM and other rheumatic
patients. Obesity and overweight have been pointed as playing a
relevant role in FM symptoms; however, it is necessary to find out
more about this relationship.
The objective of this study was to evaluate the relationship between
body mass index (BMI), fat mass (fM) and lean mass (lM) with quality
of life in a group of FM patients. 103 women, with a mean age of 53.74
=B1 7.81, and members of different FM patient associations from Spain
participated in our study. Some anthropometric measures were taken
like weight, height, BMI, body fat mass and lean mass.
FM patients QoL was assessed by the Short-Form Health Survey, SF-36
questionnaire. Statistical reports were based on mean, standard
deviation and correlation, but significance was tested by
nonparametric methods.
BMI, fM and lM correlated differently with the specific SF-36 scores.
BMI had a high negative correlation with emotional role, fM with
bodily pain and lM almost with all scores but specially with emotional
role, vitality and physical role.
The outcome of this study reveals some interesting relationships,
which need to be further investigated to improve the management of FM
patients.
