Abstract:

A Fibromyalgia Syndrome (FMS) is a chronic illness, with unknown etiology characterized by diffuse generalized muscle pain, fatigue and non repairing sleep, which leads to a physical and psychological damage. The FMS patients show a higher fat percentage and lower index of fat free mass when compared to the general population. This condition stress the sensitivity to pain affecting the life quality. The objective of this study was to compare the results of body composition evaluation by the convencional anthropometric methodology, bioimpedance and DEXA applied in women with FMS. There were 37 participants, all female, and the data were collect with three different protocols. They were: Bioimpedance, anthropometry and DEXA. There were prevalence of 27% and 37% over weight and obesity respectively, although in relation to the fat mass, it can be concluded that all correlations found by the results from the three used methods are very strong (r > 0,9). About the lean mass, a very strong correlation was found (r = 0,902) only with bioimpedance and DEXA only. It can be concluded that the usage of the three methodologies (anthropometry, bioimpedance and DEXA) to evaluate fat and lean mass are valid and useful to analyze the nutrition state evolution of women who present Fibromyalgia Syndrome.
