Prevalence of chronic kidney disease among Chinese adults with diabetes: a nationwide population-based cross-sectional study
Abstract
Summary Background To date, comprehensive data on the distribution of chronic kidney disease (CKD), the most prevalent comorbidity in diabetes, among Chinese adults with diabetes is lacking. Additionally, research gaps exist in understanding the association between CKD and cardiovascular health (CVH), an integrated indicator of lifestyle and metabolic control, within a nationwide sample of Chinese adults with diabetes. Methods A nationally community-based cross-sectional survey was conducted in 2018–2020. 58,560 residents diagnosed with diabetes aged 18–74 years nationwide were invited to participate, and 52,000 participants with complete CKD data were included in this study. CKD was identified by the presence of albuminuria (urine albumin-to-creatinine ratio ≥30 mg/g) and/or decreased estimated glomerular filtration rate (eGFR, <60 mL/min/1.73 m2). The latter was calculated using the CKD-EPI equation incorporating serum cystatin C and creatinine. CVH was evaluated using the “life's essential 8” (LE8) score, which ranged from 0 to 100 and included 8 components: diet, sleep duration, physical activity, nicotine exposure, hemoglobin A1c, blood pressure, non–high-density lipoprotein cholesterol, and body mass index. The total LE8 scores were categorized into low (0–49), middle (50–79), and high (80–100) according to the American Heart Association. The associations of albuminuria and decreased eGFR with potential associated factors, including CVH, socioeconomic status, clinical…
