Context:
Metabolic disorders and cardiovascular disease (CVD) threaten human health. Many studies have assessed the phenomenon of metabolic disorders and CVD in patients with diabetes. However, in euglycemic individuals, the relationships between glucose regulation, metabolism, and CVD remain unclear.
Objective:
This work aimed to explore the associations between postprandial glucose dips, metabolic disorders, and CVD risk.
Methods:
We analyzed data from the Thyroid disorders, Iodine status and Diabetes Epidemiological survey (TIDE study), which included 38 878 euglycemic individuals from all 31 provinces of mainland China. The prevalence of metabolic disorders and their related components and CVD risk were calculated according to postprandial glucose dips. Logistic regression models of quartiles of postprandial glucose dips were used to further explore whether the prevalence of these disorders was associated with postprandial glucose dips.
Results:
Odds ratios for the fourth vs the first quartile of glucose dips were 0.59 (95% CI, 0.55-0.63) (P < .001) for metabolic disorders, 0.48 (95% CI 0.44-0.53) (P < .001) for metabolic syndrome (MetS), and 0.54 (95% CI, 0.50-0.59) (P < .001) for hyperuricemia. The odds ratio of a 10-year CVD risk greater than 20% for the fourth vs the first glucose dip quartile was 0.67 (95% CI, 0.52-0.85) (P < .001). Models adjusted for body mass index yielded similar results.
Conclusion:
Postprandial glucose dips are associated with metabolic disorders, MetS and its related component diseases, and CVD risk. Glucose dips may be a marker of underlying metabolic abnormalities.
