Abstract
Few studies have evaluated the global burden of chronic kidney disease (CKD) in adolescents and young adults (AYAs). Age-standardized rates of incidence (ASIR), mortality (ASMR), and disability-adjusted life-years (ASDR) were used to describe the CKD burden in AYAs. The estimated annual percentage changes (EAPCs) were calculated to evaluate the temporal trends from 1990 to 2019. Risk factors were calculated by population attributable fractions. In 2019, the ASIR, ASMR, and ASDR of CKD in AYAs were 32.21 (95% uncertainty interval [UI], 23.73-40.81) per 100,000, 2.86 (2.61-3.11) per 100,000 and 236.85 (209.03-268.91) per 100,000, respectively. The ASIR was higher among females than males, whereas the ASMR was higher among males than females in 2019. From 1990 to 2019, significant increases in ASIR were found for CKD (EAPC, 0.98%; 95% confidence interval [CI], 0.95%-1.01%), although the ASMR had decreased (EAPC, -0.40%; 95% CI, -0.56% to -0.24%). The largest increase in ASIR was observed in countries with a middle sociodemographic index (SDI) (EAPC, 1.30%; 95% CI, 1.28%-1.33%), while the largest increase in ASMR was observed in high SDI. Globally, the proportional contribution of risk factors for CKD mortality varied across regions, with the highest proportions of high fasting plasma glucose being 14.04% in low SDI, compared with 24.01% in high SDI. CKD is a growing global health problem in AYAs, especially in countries with a middle SDI. Targeted measures are needed to address the rising burden of CKD in AYAs, focusing on prevention, early diagnosis, and reducing disparities.
