BACKGROUND: The relationship between orthostatic blood pressure (BP) changes and incident chronic kidney disease (CKD) has not been explored in Asian populations.
METHODS: We reviewed the data of 7,039 participants from the Ansung-Ansan cohort study. BP was measured in the supine position and 2 minutes after standing. The change in BP from the supine to upright position was defined as orthostatic BP change. Orthostatic systolic BP (SBP) decline was defined as an orthostatic SBP change of <-2 mm Hg. The primary outcome was the development of CKD, defined as the first event of an estimated glomerular filtration rate <60 ml/min/1.73 m2 at least twice during the follow-up period.
RESULTS: Of 7,039 participants, 949 (13.5 %) developed incident CKD over a mean of 11.9 years. Although orthostatic diastolic BP change was not associated with incident CKD, every 1 mm Hg increase in orthostatic SBP change was associated with a decreased risk of incident CKD (HR, 0.989; 95% CI, 0.982-0.995; P = 0.001). Orthostatic SBP decline was associated with an increased risk of incident CKD (HR, 1.337; 95% CI, 1.163-1.537; P < 0.001). Older age and diabetes were associated with increased odds of orthostatic SBP decline, whereas male sex and high body mass index were associated with decreased odds of orthostatic SBP decline. Subgroup analysis revealed that orthostatic SBP decline was associated with incident CKD only in non-diabetic participants.
CONCLUSIONS: Orthostatic SBP decline was independently associated with an increased risk of future incident CKD, whereas orthostatic DBP decline was not.
