Objectives: We assessed body composition, level of physical activityand cognitive dysfunction in patients with new low-energyfractures.Methods: The study group included 33 patients (28 women) withnew low-energy fracture. The average age was 75.7±12.6 y. Weassessed the level of physical activity, and MMSE (Mini-MentalState Examination) score. We performed bioelectrical impedanceanalysis to assess body composition.Results: The mean MMSE score was 20,8±8.4. 17 patients (52%)had MMSE score more or equal 24 (no dementia), 6 patients(18%) demonstrated mild dementia, 6 patients (18%) demonstratedmoderate dementia, and 4 patients (12%) showed severecognitive impairment. We assessed patients’ physical activitywith the original questionnaire, where 0 means bed-ridden levelof physical activity (2 patients, 6%), 1 means ambulatory withinown apartment/house (11 patients, 33%), 2 means ambulatoryto and from a shop/workplace (13 patients, 39%), 3 means dailywalking no <2 hours (4 patients, 12%), 4 means moderate physicalactivity daily (1 patient, 3%), 5 means vigorous physical activitymost days of the week (1 patient, 3%). We asked about the numberof spontaneous falls during the last year. The mean numberwas 2.1±2.8 (quartile 1 to quartile 3, 0.0-4.0). The weight meanwas 80.3±5.5 kg in men and 68.2±13.9 kg in women. The meanfat mass value was 20.5±9.7 kg. Fat free mass mean value was54.7±9.1 kg in men and 48.5±9.1 kg. Mean skeletal muscle massin men was 31.0±5.2 kg, mean skeletal muscle mass in womenwas 27.5±3.4 kg. There was no correlation between number offalls for the last year and level of physical activity of MMSE score.We found a negative correlation between the level of physical activityand number of falls for the last year (Rs=- 0.69; p<0.05).We couldn’t find any correlation between weight of different bodycompartments and the MMSE level, level of physical activity, andnumber of falls.Conclusion: Patients with new low-energy fractures demonstratedhigh prevalence of cognitive impairment and low level of physicalactivity. There was a significant correlation between the levelof physical activity and number of spontaneous falls.
