Overview

Global modeling study demonstrates high chronic kidney disease burden attributable to poor diet across 204 territories, indicating distinct disparities tied to socioeconomic status.

Key Points

  • To quantify the global, regional, and national burden of chronic kidney disease attributable to specific dietary risk factors between 1990 and 2021.
  • Extracted disability-adjusted life-year (DALY) estimates from the Global Burden of Disease Study 2021 across 204 countries and territories.
  • Assessed 7 dietary risk factors for chronic kidney disease stratified by age, sex, Socio-demographic Index (SDI), and underlying causes including type 2 diabetes mellitus and hypertension.
  • In 2021, the global age-standardized DALY rate of chronic kidney disease attributable to dietary risks was 93.52 (95% UI: 54.29–134.38) per 100,000, with low fruit intake (38.68 [95% UI: 20.15–57.77]), low vegetable intake (30.84 [95% UI: 14.80–50.20]), and high sodium intake (19.81 [95% UI: 2.51–54.57]) as leading contributors.
  • Low SDI regions experienced higher hypertension-related CKD burden from fruit (54.23) and vegetable (55.99) deficiencies, while high SDI regions showed greater diabetes-related CKD burden from processed meat (11.36), red meat (6.59), and sugar-sweetened beverages (4.01; a 121.08% increase).
