%X The aim of this study was to determine whether the blood pressure (BP) classification recommended in the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) hypertension guidelines is useful for the prediction of chronic kidney disease (CKD) in adults. We conducted a retrospective cohort study using annual health check data in Iki City, Nagasaki, Japan. A total of 3269 adults without CKD, who were not on BP-lowering medication, were included in the present analysis. BP was classified as: normal (systolic BP (SBP)£¿<120£¿mmHg and diastolic BP (DBP)£¿<80£¿mmHg), elevated BP (120£¿¡Ü£¿SBP£¿<£¿130 and/or DBP£¿<£¿80), stage 1 hypertension (130£¿¡Ü£¿SBP£¿<£¿140 and/or 80£¿¡Ü£¿DBP£¿<£¿90), and stage 2 hypertension (SBP£¿¡Ý£¿140£¿mmHg and/or DBP£¿¡Ý£¿90£¿mmHg). The primary outcome of the study was new-onset CKD. The effects of BP on the development of CKD were evaluated using Cox¡¯s proportional hazards modelling. During a mean follow-up of 4.8 years, 472 (14.4%) participants developed CKD. The incidence (per 1000 person-years) of new-onset CKD was higher in individuals with elevated BP. After adjustment for other risk factors, there were significant associations between elevated BP and new-onset CKD: hazard ratio 1.11 (95% confidence interval 0.87¨C1.42) in elevated BP, 1.25 (1.01¨C1.54) in stage 1 hypertension, and 1.45 (1.18¨C1.79) in stage 2 hypertension, compared with the reference group with normal BP (P£¿<£¿0.001 for trend). Thus, the findings of this study confirm the definition of hypertension (¡Ý130/80£¿mmHg) recommended by the 2017 ACC/AHA guidelines for the management of hypertension to be useful for the prediction of new-onset CKD
