Serum N-Terminal Pro-B-Type Natriuretic Peptide Is Associated With Insulin Resistance in Chinese: Danyang Study.

Abstract

The association of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) with insulin resistance (IR), as measured by homeostasis model assessment of insulin resistance (HOMA-IR), in the general population is unclear. Our study aimed to characterize its relationship in a large community-based population. Subjects were recruited from the Danyang city between 2017 and 2019. Serum NT-proBNP was measured using an enhanced chemiluminescence immunoassay. IR was defined by a HOMA-IR in the highest sex-specific quartile. Categorical and continuous analyses were performed with sex-specific NT-proBNP tertiles and naturally logarithmically transformed NT-proBNP (lnNTproBNP), respectively. The 2945 participants (mean age 52.8 years) included 1728 (58.7%) women, 1167 (39.6%) hypertensive patients, 269 (9.1%) diabetic patients, and 736 (25.0%) patients with IR. In simple and multivariate-adjusted regression analyses, serum lnNTproBNP were both negatively associated with HOMA-IR (β = -0.19 to -0.25; p < 0.0001). Similar results were also obtained in multiple subgroup analyses. In multiple logistic regression analyses, elevated serum NT-proBNP was associated with lower risks of IR (odds ratios: 0.68 and 0.39; 95% confidence intervals: 0.61-0.74 and 0.30-0.50 for lnNTproBNP and top vs. bottom tertiles, respectively; p < 0.0001). In conclusion, increased serum NT-proBNP level was strongly associated with a lower risk of IR in Chinese.
