Abstract
BACKGROUND
Dietary fiber (DF) intake may have a protective effect against type 2 diabetes (T2D); however, its relationship with diabetic kidney disease (DKD) remains unclear.
AIM
To investigate the potential association between DF intake and the prevalence of DKD in individuals diagnosed with T2D.
METHODS
This cross-sectional study used data from the National Health and Nutrition Examination Survey collected between 2005 and 2018. DF intake was assessed through 24-h dietary recall interviews, and DKD diagnosis in individuals with T2D was based on predefined criteria, including albuminuria, impaired glomerular filtration rate, or a combination of both. Logistic regression analysis was used to assess the association between DF intake and DKD, and comprehensive subgroup and sensitivity analyses were performed.
RESULTS
Among the 6032 participants, 38.4% had DKD. With lower DF intake-T1 (≤ 6.4 g/1000 kcal/day)-as a reference, the adjusted odds ratio for DF and DKD for levels T2 (6.5-10.0 g/1000 kcal/day) and T3 (≥ 10.1 g/1000 kcal/day) were 0.97 (95%CI: 0.84-1.12, P = 0.674) and 0.79 (95%CI: 0.68-0.92, P = 0.002), respectively. The subgroup analysis yielded consistent results across various demographic and health-related subgroups, with no statistically significant interactions (all P > 0.05).
CONCLUSION
In United States adults with T2D, increased DF intake may be related to reduced DKD incidence. Further research is required to confirm these findings.
Core Tip: This cross-sectional analysis of National Health and Nutrition Examination Survey data, spanning 2005 to 2018, explored the potential correlation between dietary fiber (DF) intake and the prevalence of diabetic kidney disease (DKD) in individuals diagnosed with type 2 diabetes (T2D). The study, which involved 6032 participants, reveals that higher DF intake, particularly in the tertile with ≥ 10.1 g/1000 kcal/day, is associated with a statistically significant reduction in DKD incidence. These findings suggest a potential protective effect of increased DF intake against DKD in adults with T2D in the United States. Further investigation is warranted to corroborate these observations.
