RESUMEN
This study aims to investigate both the prevalence and associated factors of frailty, pre-frailty, and each criterion of frailty according to the Fried phenotype criteria among older adult outpatients receiving care from geriatric services. A cross-sectional study was conducted between 2020 and 2022 and included 335 older adults. Fried's criteria and a comprehensive geriatric assessment, including physical, clinical and mental health variables were investigated. More than half of participants presented frailty (11.6 %) and/or pre-frailty (43.3 %) according to Fried's criteria, with physical inactivity and low gait speed as the most prevalent criteria. Several factors demonstrated associations with the diagnosis of frailty/pre-frailty, including retirement status, marital status (unmarried), the use of walking aids, lower educational attainment, decreased functional status, and poor mental health. Furthermore, various factors were associated with each of Fried's criteria, highlighting that certain factors might align with a specific criterion without necessarily correlating with the diagnosis of frailty and pre-frailty.
RESUMEN
Purpose: We evaluated the effects of supervised intradialytic resistance training on physical activity in daily life (PADL), muscle strength, physical capacity and quality of life (QoL) in hemodialysis patients.Methods: Twenty-four hemodialysis patients were randomly assigned to either a 12-weeks moderate-intensity resistance training or a control period. An accelerometer evaluated PADL for seven consecutive days, measuring the time spent in different activities and positions of daily routine and the number of steps taken. Muscle strength, physical capacity and QoL were evaluated.Results: After 12 weeks of training, we did not find significant difference (post-pre values) in walking time (-1.2 ± 18.3 vs. -9.2 ± 13.1 min/day); standing time (-10.2 ± 28.6 vs. 3.2 ± 20.1 min/day); sitting time (20.8 ± 58.9 vs. -30.0 ± 53.0 min/day); lying down time (-9.3 ± 57.9 vs. 34.6 ± 54.0 min/day); number of steps taken [-147 (1834) vs. -454 (2066)] and muscle strength in training and control group, respectively. There was a significant increase in the six-minute walking test distance (48.8 ± 35.9 vs. 6.9 ± 45.9 m, p < 0.05) and some domains of QoL in the training compared to the control group.Conclusions: PADL was not modified after 12 weeks of intradialytic resistance training in hemodialysis patients. However, the exercise program was able to increase the physical capacity and some domains of QoL.Implications for rehabilitationPhysical activity in daily life was not modified after 12 weeks of intradialytic resistance training in hemodialysis patients.The exercise program was able to increase the physical capacity, efficacy of dialysis and some domains of quality of life in hemodialysis patients.The protocol used in this study was safe since no complications were observed during and after resistance training.These results should be interpreted with caution because we applied a moderate resistance training in both lower limbs and in the contralateral arteriovenous fistula upper limb, using perceived exertion by Borg scale to exercise prescription. Moreover, the safety protocol evaluation was not conducted.
