Objective. To determine the clinical manifestations associated with overweight/obesity in Hispanics from Puerto Rico with
ibromyalgia syndrome (FMS). Methods. A cross-sectional study was performed in 144 patients with FMS (per American College of
Rheumatology (ACR) classiication criteria). Sociodemographic features, FMS-related symptoms, tender points (per ACR criteria),
comorbidities, and FMS treatment were examined. BMI was calculated and patients were grouped into two categories: BMI ≤
24.9 kg/m
2
(nonoverweight/obese) and BMI ≥ 25 kg/m
2
(overweight/obese). Bivariate and multivariate analyses were used to
evaluate diferences between the study groups. Results. he mean (standard deviation (SD)) age of patients was 50.2 (9.9) years;
95.1% were females and 75.7% were overweight/obese. In the bivariate analysis, overweight/obese patients were more likely to
have self-reported memory impairment, anxiety, shortness of breath, and urinary frequency than nonoverweight/obese patients.
In addition, the tender point count was higher in the overweight/obese group. In the logistic regression analyses, self-reported
memory impairment and urinary frequency diferences remained signiicant ater adjusting for confounding variables. Conclusion.
In this population of Puerto Ricans with FMS, overweight/obese patients experienced more FMS-related manifestations than
nonoverweight/obese individuals. However, prospective studies are needed to conirm these associations and to elucidate if weight
reduction interventions could favorably impact the severity of FMS.
1. Introduction
Fibromyalgia syndrome (FMS) occurs predominantly in
women and is characterized by difuse musculoskeletal
pain, tiredness, sleep disorder, headaches, and cognitive
impairment, among several other manifestations [1, 2]. he
exact pathogenesis of FMS remains to be elucidated as well
as the contributing factors associated with the severity of
symptoms [3–6]. Obesity and overweight status are common
comorbidities in FMS patients [3, 4, 7]. Obesity is associated
with increased sensitivity to pain, poor health status, and
a low health-related quality of life [8–10]. Because obesity
and FMS share some clinical features it is not surprising
that some studies have found that FMS patients with obesity
have worse symptoms including higher pain perception,
lower physical strength, poorer sleep quality, and lower self-
reported quality of life [3, 4, 6]. In addition, obesity was found
to be an independent risk factor for FMS in a longitudinal
cohort of Norwegian women [11]. he full spectrum of FMS
manifestations has not been fully studied in overweight/obese
FMS patients. hus, we sought to examine the clinical
manifestations associated with overweight/obesity in a group
of Puerto Ricans with FMS.
