Aim: To investigate the gender and socioeconomic disparities in the global burden of chronic kidney disease (CKD) due to glomerulonephritis from 1990 to 2019.
Methods: Data were extracted from the global burden of diseases (GBD) 2019 study, including incidence, prevalence and disability-adjusted life-years (DALYs). Estimated annual percentage changes (EAPCs) were calculated to quantify the temporal trends in age-standardized rate (ASR) of CKD due to glomerulonephritis. Paired t-test, paired Wilcoxon signed-rank test and Spearman correlation were performed to analyse the association and gender disparity in CKD due to glomerulonephritis.
Results: Globally, incident cases of CKD due to glomerulonephritis increased 81% from 9 557 397 in 1990 to 17 308 071 in 2019. The age-standardized incidence rate increased by 1.47 compared with 1990 and DALYs increased by 1.35 compared with 1990 (per 100 000). The number of patients with CKD due to glomerulonephritis in low-middle SDI (3829917) and middle SDI (6268817) regions accounts for more than 55% of the total cases. CKD due to glomerulonephritis caused a higher burden including the incidence rate (p < .0001) and DALY rate (p < .0001) in men compared to women. The age-standardized DALY rate was negatively correlated with SDI (ρ = -0.64, p < .001). In the analysis of risk factors for DALYs, male individuals had a larger burden of hypertension, high BMI and high sodium diet in the DALY rates than female subjects.
Conclusion: The burden of CKD due to glomerulonephritis was more skewed towards developing and less developed economies and differed by gender, so certain nations should implement far more focused and targeted policies.
