| bers of the EXERNET research network. Introduction: A previous study showed that body composition assessment in women over 55 by bioelectric impedance analysis (BIA) had some signifi cant deviations according to Dual X-ray absorptiometry (DXA) which is considered the gold standard on body composition measure. The aim of this study was to identify any factors that might cause an erroneous estimation in body fat and muscular mass assessment in women over 55 when using BIA. Method: BIA analysis (TANITA Corp, BC-418MA) and DXA (GE/Lunar- PRODIGY. GEHealthCare, Wisconsin, USA) were applied to a sub-sample of the FIS PI11/01791 study (58 women, 55-82 years old). The variables analysed were body mass, fat mass percentage and muscular mass percentage. The EXERNET questionnaire was used to determine the daily time spent walking and performing sedentary activities. As covariates taken into account were age, height, body mass index, waist and hip perimeter and arm muscle strength measured with the arm curl test. Results: There was a signifi cant and positive correlation (p<0.01) between both methods for all study variables, although weight and fat mass are slightly underestimated and fat-free mass overestimated with BIA. However, diff erences greater than 6 percentage points were observed on 2 women (3.4% of the sample) in body mass assessment and on 11 participants (19%) in muscular mass percentage. When compared with the rest of the sample, these participants showed signifi cant diff erences (p<0.05) in daily time spent walking and the best result on arm curl tests (which were higher than those of the rest of the sample). There were also variations in body mass, hip perimeter, time spent sitting per day and practising intense physical activity per week (> 5 MET), although these diff erences were not signifi cantConclusions: BIA is an adequate method for measuring body composition in the frame of our study.
