Physical Fitness In Chronic KidneyDisease Patients: A Cross-sectional Study

PURPOSE: Low physical fitness (PF) has been associated with deterioration in overall health outcomes, resulting in an increased hospitalizations, morbidity, and mortality in patients treated with maintenance dialysis. To compare self-reported PF between chronic kidney disease (CKD) patients undergoing treatment with maintenance dialysis and healthy individuals without chronic kidney disease. METHODS: In this cross-sectional study 674 CKD patients and 518 healthy individuals self-reported PF by completing the International Fitness Scale (IFIS). Ratings are separated into five dimensions of PF; general, cardiorespiratory, strength, agility, and flexibility. Odds ratio analyses were adjusted for sex, age, skin color, schooling, diabetes, smoking, physical activity, sedentary behavior, and body max index. RESULTS: CKD patients were more likely to self-report lower general (OR = 2.03, p = 0.001), cardiorespiratory (OR = 3.18, p < 0.001), strength (OR = 2.51, p < 0.001) and agility fitness (OR = 1.83, p < 0.001) in comparison to the health control group. There was no difference in self-reported flexibility (p > 0.050). CONCLUSIONS: CKD patients presented lower perception of PF than individuals without CKD supporting the need for proper exercise prescription within this group. - Odds of self-reported low physical fitness between CKD patients and healthy controls (n = 1192) OR 95%CI P General 2.03 1.35-3.05 0.001 Cardiorespiratory 3.18 2.27-4.46 <0.001 Strength 2.51 1.71-3.68 <0.001 Flexibility 1.20 0.84-1.71 0.313 Agility 1.83 1.26-2.64 0.001
