The Kidney Early Evaluation Program (KEEP): Program Design and Demographic Characteristics of the Population

Cumulative number of Kidney Early Evaluation Program participants and affiliates.

Kidney Early Evaluation Program participants who have a physician, by age, sex, race, and ethnicity (n = 73,460).

Demographic characteristics for Kidney Early Evaluation Program (KEEP) and National Health and Nutrition Examination (NHANES) participants. For comparison purposes, the KEEP data set is restricted to participants 20 years and older (n = 72,963), and the NHANES data set, to participants 20 years and older with 1 or more of the following: self-reported hypertension, self-reported diabetes, and family history of hypertension, stroke, or diabetes (n = 10,865). Missing KEEP data were included in the analysis; however, χ² values were similar regardless of whether missing data were included. For sex, 0.09% of data were missing, and for race, 0.6%.

Education level of Kidney Early Evaluation Program (KEEP) and National Health and Nutrition Examination (NHANES) participants by race and ethnicity. For comparison purposes, the KEEP data set is restricted to participants 20 years and older (n = 72,963), and the NHANES data set, to participants 20 years and older with 1 or more of the following: self-reported hypertension, self-reported diabetes, and family history of hypertension, stroke, or diabetes (n = 10,865). Missing KEEP data (3.5% of data) were included in the analysis; however, χ² values were similar regardless of whether missing data were included.

Insurance status for Kidney Early Evaluation Program (KEEP) and National Health and Nutrition Examination (NHANES) participants by race and ethnicity. For comparison purposes, the KEEP data set is restricted to participants 20 years and older (n = 72,963), and the NHANES data set, to participants 20 years and older with 1 or more of the following: self-reported hypertension, self-reported diabetes, and family history of hypertension, stroke, or diabetes (n = 10,865). Missing KEEP data (6.1%) were included in the analysis; however, χ² values were similar regardless of whether missing data were included.

Prevalence of self-reported comorbid conditions and chronic kidney disease (CKD) for Kidney Early Evaluation Program (KEEP) and National Health and Nutrition Examination (NHANES) participants. CKD is defined as estimated glomerular filtration rate (eGFR) less than 60 mL/min/1.72 m² (<1.0 mL/s/1.72 m²) or eGFR of 60 mL/min/1.72 m² or greater (≥1.0 mL/s/1.72 m²) and albumin creatinine ratio of 30 mg/g or greater. For comparison purposes, the KEEP data set is restricted to participants 20 years and older (n = 72,963), and the NHANES data set, to participants 20 years and older with 1 or more of the following: self-reported hypertension, self-reported diabetes, and family history of hypertension, stroke, or diabetes (n = 10,865). Missing KEEP data were included in the analysis. Reported χ² values were similar regardless of whether missing data were included. Abbreviations: SR, self-reported; DM, diabetes mellitus; HTN, hypertension; CVD, cardiovascular disease; KD, kidney disease.
