Performance of Current Chronic Kidney Disease Screening Criteria in Women and Men Across Ethnic Groups: The HELIUS Study

Objective: To investigate whether the currently recommended screening criteria in Kidney Disease: Improving Global Outcomes 2024 guidelines (hypertension, diabetes mellitus, and cardiovascular disease) equally detect women and men across ethnic groups and whether consideration of optional criteria (education level, occupation, obesity, and genetic risk factors) listed in the guideline improves performance. Patients and Methods: or albumin-to-creatinine ratio of >3 mg/mmol. Poisson regression analyses estimated associations between CKD and optional criteria on top of current screening criteria. Model comparisons were made with likelihood ratio tests and Akaike information criterion estimations in women and men. Area under the curve (AUC), sensitivity, specificity, and positive and negative predictive values were calculated by sex and ethnicity. Results: Chronic kidney disease prevalence ranged from 2.9% to 8.8% in women and 3.2% to 8.6% in men. Low educational level (women only) and obesity significantly improved the models with current criteria with CKD. High-risk occupations and polygenic risk score did not improve the model. However, these criteria did not improve predictive measures across ethnic groups. Overall, the AUCs for the current screening criteria were acceptable in men (AUC, 0.75; 95% CI, 0.73-0.77) and poor in women (AUC, 0.65; 95% CI, 0.63-0.67), and showed minimal change after adding the optional criteria. Conclusion: Current screening criteria may not be equally detecting women and men across ethnic groups with CKD. Optional criteria had limited added value.
