Background

Chronic kidney disease (CKD) is a leading risk factor for cardiovascular disease (CVD). Asian adults in the United States (US) have high rates of CVD. We hypothesized that Asian adults have a higher burden of CKD and associated conditions than White individuals, and risk may vary across Asian ethnicities.

Methods

Using cross-sectional data from NHANES 2011-2018 (N=21,566), we calculated weighted, age-adjusted prevalence of CKD and associated conditions (hypertension (HTN), diabetes (DM), obesity, metabolic acidosis, albuminuria, CVD) among non-Hispanic adults. CKD was defined as an estimated GFR<60ml/min per 1.73m² or albuminuria ≥30mg/g. Using the National Health Interview Survey (NHIS;N=14,194), we explored heterogeneity in self-reported prevalence across Asian ethnicies.

Results

The NHANES population was 37% White, 23% Black, 13% Asian, and 28% other race, with a mean age of 48 years. Overall CKD prevalence was 12.7% (95%CI 12.1, 13.4). Asians had a 1.5- and 1.3-fold higher prevalence of CKD compared to White and Black participants, respectively. Among Asians, the prevalence of HTN and obesity increased over time (p-trend=0.001 for both) and remained significantly greater than among White and Black participants throughout the study period. In the NHIS, there was higher prevalence of HTN and obesity among Filipino participants and lower prevalence of HTN, DM, and obesity among Chinese participants.

Conclusion

Analysis of nationally representative data from the US demonstrates a disproportionately high prevalence of CKD and associated conditions among Asian adults, with prevalence rates for some conditions exceeding those of Black and White participants.
