Impact of Physical Activity on Patients With Chronic Kidney Disease Not Receiving Dialysis Followed in the TIRCEL Network. An Exposed / Unexposed Study (PHYSALYS)

Completed

• Conditions: Renal Insufficiency, Chronic
• Interventions: Other: Global Physical Activity Questionnaire

• Registration Number: NCT02818010
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

PHYSALYS is an observational multicenter study. It's an analytical study comparing 2 groups: patients exposed to physical activity and unexposed. The main objective of the study is to compare the evolution of glomerular filtration rate at inclusion and 12 months later between patients practicing physical activity and patients not practicing. If necessary, the renal disease-related complications, which are not influenced by physical activity: (type of kidney disease, age and tobacco), would be taken into account. TIRCEL patients with chronic kidney disease (CKD) at stages 3, 4 or 5 can be included in the study. Their serum creatinine data, 12 months prior to inclusion, is collected retrospectively. Patients are followed in the trial during 12 months. To evaluate physical activity, patients respond to Global Physical Activity Questionnaire 2 (GPAQ2) at inclusion and 12 months later. During this 12 months period, the same biological data are collected prospectively.

Arm && Interventions

Group	Intervention	Description
exposed = patient practicing physical activity	Global Physical Activity Questionnaire	The practice of physical activity is measured by the GPAQ 2 questionnaire (Global Physical Activity Questionnaire) A patient is defined as practicing physical activity (exposed) when he meets one of the conditions following: * At least 20 minutes of vigorous-intensity physical activity for at least 3 days per week * At least 30 minutes of moderate-intensity physical activity or walking daily for at least 5 days per week * At least 5 days of walking and moderate- or vigorous-intensity physical activity achieving at least 600 MET-minutes per week. The Metabolic equivalents (MET) is the ratio of metabolic rate during activity physical and metabolic rate at rest. One MET corresponds to the energy spent by a person sitting still and is equivalent to a consumption of 1 kcal / kg / hour. It is estimated that a moderately active person has an energetic cost four times higher, and a very active person eight times higher than the energy cost of a person sitting without move.
unexposed = patient not practicing physical activity	Global Physical Activity Questionnaire	The practice of physical activity is measured by the GPAQ 2 questionnaire(Global Physical Activity Questionnaire) A patient is defined as unexposed if he does not fulfill any of these conditions : * At least 20 minutes of vigorous-intensity physical activity for at least 3 days per week * At least 30 minutes of moderate-intensity physical activity or walking daily for at least 5 days per week * At least 5 days of walking and moderate- or vigorous-intensity physical activity achieving at least 600 MET-minutes per week. The Metabolic equivalents (MET) is the ratio of metabolic rate during activity physical and metabolic rate at rest. One MET corresponds to the energy spent by a person sitting still and is equivalent to a consumption of 1 kcal / kg / hour.

Primary Outcome Measures

Name	Time	Method
Change of the Glomerular Filtration Rate (GFR)	Month 0, Month 12	The Glomerular Filtration Rate (GFR) annual slope between inclusion (M0) and 12 months (M12) after inclusion in exposed and unexposed groups.
