Cardiometabolic & kidneyCross-sectional study
Chronic Kidney Disease Prevalence and Awareness Among US Adults
- Serial cross-sectional study
- nationally representative
- survey-weighted
Authors' conclusion
In this nationally representative study, CKD affected 1 in 6 US adults with cardiometabolic conditions, and only a minority of respondents were aware of "weak/failing" kidneys.
Study context
- Population
- US adults aged ≥20 y in NHANES 2011–March 2020, overall and with cardiometabolic risk factors (hypertension, DM, hyperlipidemia, obesity) or cardiovascular disease (CVD)20,224 with cardiometabolic risk factors or CVD
- Participants
- 24,646 adults
- Outcome
- CKD prevalence (eGFR <60 mL/min/1.73 m² or urine albumin to creatinine ratio ≥30 mg/g) and awareness (self-reported "weak/failing kidneys")
Main finding
As reported in the abstract
Chronic kidney disease (CKD) prevalence, all US adults
14.6% (95% CI, 14.0%-15.3%)
Awareness of weak/failing kidneys, all US adults
12.3% (95% CI, 11.1%-13.5%)
CKD prevalence, adults with cardiometabolic risk factors or CVD
16.7% (95% CI, 16.0%-17.4%)
Awareness, adults with cardiometabolic risk factors or CVD
13.2% (95% CI, 11.9%-14.4%)
Observational data: associations, not effects.
Further findings
Temporal change in awareness, CKD with cardiometabolic conditions · 2011-2012 to 2017 through March 2020
- Overall: 11.5% (95% CI, 8.5%-14.5%) to 15.1% (95% CI, 13.1%-17.2%)
- P = 0.02
- Aged ≥65 y: 10.8% (95% CI, 6.9%-14.6%) to 17.7% (95% CI, 14.2%-21.3%)
- Men: 9.7% (95% CI, 5.6%-13.8%) to 18.4% (95% CI, 15.5%-21.4%)
- Non-Hispanic White: 10.8% (95% CI, 6.1%-15.5%) to 16.3% (95% CI, 13.4%-19.2%)
- No significant improvement among aged 20 to 64 y, women, or Black and Hispanic adults
Awareness gaps, cardiometabolic risk factors or CVD
- Largest awareness gaps among aged 20 to 64 y, women and Hispanic adults
