Identifying Undetected Cases of Chronic Kidney Disease in Mexico. Targeting High-risk Populations

Background and Aims c kidney disease (CKD) is a major public health problem in Mexico. Current guidelines recommend routine CKD testing in patients at increased risk for CKD. We undertook this study to examine the diagnostic yield of targeted screening (case-finding) for CKD in high-risk populations in rural and urban communities in Jalisco, Mexico. s ross-sectional study, we did laboratory tests searching for CKD and its risk factors and compared the characteristics of participants with those reported by the National Health and Nutrition Survey 2006 (NHNS). Individuals who were aware that they had CKD and those <18 years of age were excluded. s were 9,169 participants assessed: 28.7% were men and mean age was 55.6 ± 13.7 years. They were predominantly female (71.3 vs. 55.6%, p = 0.0001) and older (55.59 ± 0.1 vs. 42.5 ± 0.3 years, p = 0.0001) than the NHNS population. Self-reported diabetes (41.9 vs. 7.3%, p = 0001) and fasting blood sugar >126 mg/dl (56.1 vs. 14.4%, p = 0.0001) were more prevalent among the participants; self-reported hypertension (41.9 vs. 7.3%, p = 0.0001), systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg (52.5 vs. 43.2%, p = 0.0001), and obesity (42.8. vs. 29.3%, p = 0.0001) were also more frequent among participants. There were 19.7% with proteinuria; CKD was more prevalent among the high risk participants in our study (31.3 vs. 8.0%, p = 0.0001) than in the general population. sions s detected frequently in high-risk Mexican populations. Trials of case-finding and intervention are feasible and warranted in Mexico.
