Association Between Life's Essential 8 and Diabetic Kidney Disease in Patients With Diabetes Mellitus: Evidence From National Health and Nutrition Examination Survey 2005-2018

Background

Diabetic kidney disease (DKD) is often connected with an elevated cardiovascular disease risk. A novel index, the Life's Essential 8 (LE8), was developed with the American Heart Association to ascertain cardiovascular health. In people with diabetes mellitus, we aimed to estimate if LE8 possessed a connection with DKD risk.

Methods

We implemented data from the National Health and Nutrition Examination Survey from 2005 to 2018. The correlation between LE8 and DKD was evaluated with weighted multivariate logistic regression models and restricted cubic spline models with covariate adjustments. In addition, we performed subgroup analyses and interaction tests.

Results

After taking into account relevant confounding factors, the findings indicated that higher levels of LE8 was linked to a decreased probability of developing DKD (per 10-point increase in LE8, OR = 0.75, 95%CI = 0.68-0.84, P < .001). The subscales of the LE8 similarly demonstrated negative associations with DKD risk. After grouping the LE8 scores, it was found that individuals with high LE8 were significantly less likely to develop DKD compared to those with low LE8 (OR = 0.32, 95%CI = 0.15-0.70, P = .005). The association between LE8 and DKD was consistent across different subgroups.

Conclusion

LE8 scores were shown to have a significantly negative association with the risk of DKD in people with diabetes mellitus. By concentrating on the state of cardiovascular health, it may be possible to lessen the impact of DKD.
