Abstract

Abstract : Objective . Neuropeptide Y (NPY), an orexigenic peptide known to cause hyperphagia, has been involved in the occurrence and development of obesity. However, differences in the distribution of serum NPY levels in obese phenotypes (including metabolically unhealthy obesity (MUO) phenotype and metabolically healthy obesity (MHO) phenotype) and the association of NPY with MUO phenotype have not been unequivocally established. We therefore determined associations of serum NPY levels with MUO phenotype in obese Chinese adults. Methods . A cross-sectional study was conducted from 400 obese adults in Hunan province, who underwent a health examination in the Second Xiangya Hospital, and 164 participants were finally enrolled in the study and divided into MHO and MUO groups. Serum NPY levels were examined; univariate and multivariate analyses as well as smooth curve fitting analyses were conducted to measure the association of NPY serum levels with the MUO phenotype. Results . Serum NPY levels were significantly elevated in the MUO group compared with the MHO group ((667.69 ± 292.90 ) pg/mL vs. (478.89 ± 145.53 ) pg/mL, p < 0.001 ). A threshold and nonlinear association between serum NPY levels and MUO was found (p = 0.001 ). When serum NPY levels exceeded the turning point (471.5 pg/mL), each 10 pg/mL increment in the NPY serum level was significantly associated with an 18% increased odds ratio of MUO phenotype (OR: 1.18, 95% CI: 1.07–1.29, p = 0.0007 ) after adjusted for confounders. Conclusions . Higher NPY serum levels were positively correlated with MUO phenotype in obese Chinese adults.
