Association of kidney function and proteinuria with lower-extremity dysfunction in older Korean adults: a cross-sectional study.

ABSTRACT:

Background/aims

Chronic kidney disease (CKD) is associated with complications that affect physical function and mobility. This study investigated the associations between kidney function, proteinuria, and lower-extremity dysfunction.

Methods

Data were obtained from the Korean National Health Insurance Service Health Screening Program, including individuals aged 66 years who participated in the National Screening Program for Transitional Ages in Korea. Participants were stratified based on estimated glomerular filtration rate (eGFR) into four groups: Group 1 (eGFR ≥ 90 mL/min/1.73 m2), Group 2 (60 ≤ eGFR < 90 mL/min/1.73 m2), Group 3 (30 ≤ eGFR < 60 mL/min/1.73 m2), and Group 4 (eGFR < 30 mL/min/1.73 m2). Lower-extremity dysfunction was assessed using two physical tests measu
