Abstract

Background: Rates of chronic kidney disease (CKD) may change with ageing populations, rising metabolic and cardiovascular disease prevalence, increasing CKD awareness and new treatments. We examined sex-specific temporal trends in CKD incidence and prevalence from 2011 through 2021.

Methods: We conducted a population-based cohort study among adults residing in the North and Central Denmark Regions (population ∼1.5 million in 2021), utilizing routinely collected individual-level laboratory data. We identified individuals with incident or prevalent CKD, using data on plasma creatinine and urine albumin-creatinine ratios from samples performed in outpatient hospital settings or primary care. We estimated annual sex-specific crude and age-standardized incidence and prevalence and tabulated clinical characteristics.

Results: Throughout 2011-2021, CKD incidence and prevalence remained higher among females than males. A transient increase in the crude incidence was observed during 2011-2013, followed by a decrease from 11.8 per 1000 person-years in 2013 [95% confidence interval (CI) 11.5-12.1] to 10.7 in 2021 (95% CI 10.5-11.0) among females and from 10.9 (95% CI 10.7-11.2) to 10.6 (95% CI 10.3-10.8) among males. During 2011-2021, the crude prevalence increased among females from 85.1 per 1000 individuals (95% CI 84.4-85.8) to 99.9 (95% CI 99.2-100.6), and among males from 55.3 (95% CI 54.7-55.9) to 82.4 (95% CI 81.8-83.0). After age standardization, declines in incidence persisted, while the prevalence was stable among females, and the increase persisted among males.

Conclusions: The CKD incidence and prevalence remained higher among females than males during 2011-2021. Despite a notable decline in incidence rates from 2013 onwards, the crude prevalence increased during 2011-2021.
