AIM:The aim of the study was to analyze the correlations between age, BMI, fat mass, muscle mass, GFR and factors related to physical activity (PA) of predialysis individuals with chronic kidney disease (CKD).
METHODS: Into the study were enrolled 24 predialysis CKD patients: 6 male, 18 female (mean age 60.3±10.2 years, BMI 27.5±4.5 kg/m2, GFR 17.67±6.52 mL/min/1.73 m2). PA was assessed during 24-hours using the multisensor system Armband SenseWear Pro 3. Body composition (BC) was measured using bioimpedance.
RESULTS: Total energy expenditure was 32.4±5.8 kcal/kg of body mass. Number of steps was 10423±3680/day. Average lying down duration was 527±107 min, median of physical activity duration was 74 min. All analyzed factors, exept sleep duration, were dependent on the age. Fat mass and muscle mass were correlated with total energy expenditure (respectively r=-0.59, P=0.003; r=0.56, P=0.005), lying down duration (r=0.43, P=0.030; r=-0.52, P=0.009), physical activity duration (r=-0.53, P=0.008; r=0.56, P=0.004). GFR was correlated with lying down duration (r=-0.42, P=0.046).
CONCLUSION: PA of CKD patients was satisfactory – all patients demonstrated PA duration higher than 40 min. No influence of gender on the level of PA was observed, but PA decreased with the age progress. Higher level of PA was connected with favourable BC. The GFR level in the observed patients did not influence PA, except lying down duration, which was longer in patients with lower GFR.
