Background Hypertension among young adults is common. However, the effect of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), or systolic and diastolic hypertension (SDH) among young adults on chronic kidney disease (CKD) development is unknown. Methods and Results From a nationwide health screening database, we included 3 030 884 participants aged 20 to 39 years who were not taking antihypertensives at baseline examination in 2009 to 2010. Participants were categorized as having normal blood pressure (BP), elevated BP, stage 1 IDH, stage 1 ISH, stage 1 SDH, stage 2 IDH, stage 2 ISH, and stage 2 SDH. The primary outcome was incident CKD. A total of 5853 (0.19%) CKD events occurred. With normal BP as the reference, multivariable‐adjusted hazard ratios (HRs) (95% CIs) for CKD were 1.14 (95% CI, 1.04–1.26), elevated BP; 1.19 (95% CI, 1.10–1.28), stage 1 IDH; 1.24 (95% CI, 1.08–1.42), stage 1 ISH; 1.39 (95% CI, 1.28–1.51), stage 1 SDH; 1.88 (95% CI, 1.63–2.16), stage 2 IDH; 1.84 (95% CI, 1.54–2.19), stage 2 ISH; 2.70 (95% CI, 2.44–2.98), stage 2 SDH. The HRs for CKD were attenuated in the patients who were antihypertensive and began medication within 1 year of medical checkup than in those without antihypertensives. Conclusions Among Korean young adults, those with elevated BP, stage 1 IDH, stage 1 ISH, stage 1 SDH, stage 2 IDH, stage 2 ISH, and stage 2 SDH were associated with a higher CKD risk than those with normal BP. The CKD risk in ISH and IDH groups was similar but lower than that in the SDH group. Antihypertensives attenuated the risk of CKD in young adults with hypertension.

Background: Little is known regarding health outcomes associated with isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), or systolic and diastolic hypertension (SDH) among young adults with stage 1 hypertension, defined using the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline. Methods: From a nationwide health screening database, we included 6 424 090 participants, aged 20 to 39 years, who were not taking antihypertensive medication at the baseline examination in 2003 to 2007. Participants were categorized as having normal BP (untreated systolic BP [SBP] <120/diastolic BP [DBP] <80 mm Hg; n=2 665 310); elevated BP (SBP 120–129/DBP <80 mm Hg; n=705 344); stage 1 IDH (SBP <130/DBP 80–89 mm Hg; n=1 271 505); stage 1 ISH (SBP 130–139/DBP <80 mm Hg; n=255 588); stage 1 SDH (SBP 130–139/DBP 80–89 mm Hg; n=711 503); and stage 2 hypertension (SBP ≥140, DBP ≥90 mm Hg; n=814 840). The primary outcome was composite cardiovascular disease (CVD) events, including myocardial infarction, stroke, heart failure, and CVD-related death. Results: The median age of the participants was 30 years and 60.9% were male. Over a median follow-up of 13.2 years, 44 070 new CVD events occurred. With normal BP as the reference, multivariable-adjusted hazard ratios (95% CIs) for CVD events were 1.14 (1.09–1.18) for elevated BP, 1.32 (1.28–1.36) for stage 1 IDH, 1.36 (1.29–1.43) for stage 1 ISH, 1.67 (1.61–1.72) for stage 1 SDH, and 2.40 (2.33–2.47) for stage 2 hypertension. Conclusions: Among young adults, stage 1 ISH, IDH, and SDH were all associated with higher CVD risks than normal BP. The CVD risks of stage 1 ISH and IDH were similar to each other but lower than the risk of stage 1 SDH. Categorizing young adults with stage 1 hypertension further into stage 1 ISH, IDH, and SDH may improve risk stratification for identifying high-risk individuals.

Obesity has become a pandemic. It is one of the strongest risk-factors of new-onset chronic kidney disease (CKD). However, the effects of obesity and abdominal obesity on the risk of developing CKD in young adults has not been elucidated. From a nationwide health screening database, we included 3,030,884 young adults aged 20–39 years without CKD during a baseline examination in 2009–2010, who could follow up during 2013–2016. Patients were stratified into five levels based on their baseline body mass index (BMI) and six levels based on their waist circumference (WC; 5-cm increments). The primary outcome was the development of CKD. During the follow up, until 2016, 5853 (0.19%) participants developed CKD. Both BMI and WC showed a U-shaped relationship with CKD risk, identifying the cut-off values as a BMI of 21 and WC of 72 cm in young adults. The obesity group (odd ratio [OR] = 1.320, 95% confidence interval [CI]: 1.247–1.397) and abdominal obesity group (male WC ≥ 90, female WC ≥ 85) (OR = 1.208, 95%CI: 1.332–1.290) showed a higher CKD risk than the non-obesity or non-abdominal obesity groups after adjusting for covariates. In the CKD risk by obesity composite, the obesity displayed by the abdominal obesity group showed the highest CKD risk (OR = 1.502, 95%CI: 1.190–1.895), especially in those under 30 years old. During subgroup analysis, the diabetes mellitus (DM) group with obesity or abdominal obesity paradoxically showed a lower CKD risk compared with the non-obesity or non-abdominal obesity group. Obesity and abdominal obesity are associated with increased risk of developing CKD in young adults but a decreased risk in young adults with diabetes.
