Association Between Hemoglobin Glycation Index and Metabolic Syndrome in Middle-Aged and Older People

Abstract

Purpose Hemoglobin glycation index (HGI) is used to describe the difference between estimated and measured glycated hemoglobin A1c (HbA1c). The present study aimed to investigate the association between metabolic syndrome (MetS) and HGI in middle-aged and elderly Chinese. Patients and Methods In this cross-sectional study, a multi-stage random sampling method was used to select objects from the permanent residents aged 35 years and above living in Ganzhou, Jiangxi, China. The demographic information, history of illness, physical examination, and blood biochemistry data were obtained. HGI was calculated from fasting plasma glucose (FPG) and HbA1c (HGI = measured HbA1c value - predicted HbA1c value). All participants were divided into low HGI and high HGI groups using the median HGI as a cut-off value. Univariate analysis was used to detect the influencing factors of HGI, and Logistic regression analysis was adopted to analyze the relationship between significant variables found in univariate analysis, MetS, or MetS’s components and HGI. Results A total of 1826 participants were enrolled in the study, and the prevalence of MetS was 27.4%. There were 908 in the low HGI group and 918 in the high HGI group, and the prevalence of MetS was 23.7% and 31.0%, respectively. Logistic regression analysis showed that the prevalence of MetS in the high HGI group was higher than that in the low HGI group (OR=1.384, 95% CI:1.110~1.725), further analysis showed that HGI was related with abdominal obesity (OR=1.287, 95% CI:1.061~1.561), hypertension (OR=1.349, 95% CI:1.115~1.632), and hypercholesterolemia (OR=1.376, 95% CI:1.124~1.684) (all P < 0.05). After adjusting for age, sex, and serum uric acid (UA), the relationship still existed. Conclusion This study found that HGI is directly associated with MetS.

Síndrome metabólico y hemoglobina glicosilada en Latinoamérica

“…Huang, X y col, evidenciaron durante el 2023 en una investigación de cohorte prospectivo de 4074 participantes que los niveles de HbA1c estaban estrechamente relacionados con la incidencia de síndrome metabólico durante el seguimiento (Huang et al, 2023). Xie, S y col en el año 2023 realizaron un estudio a 1826 pacientes, donde encontraron que en 918 pacientes los niveles de hemoglobina glicosilada estaban alterados, relacionándose directamente con el padecimiento de síndrome metabólico (Xie et al, 2023).…”
