Abstract:
Objective Serum glycated albumin (GA) is associated with the levels of blood glucose and short term glycemic fluctuation. The aim of this study was to investigate the associations between GA and arterial stiffness in a health screening population. Method A total of 11 014 participants (men, 56.2%;mean age, 46.8±7.8 years) who attended physical examination were invited and had completed standardized questionnaires. Serum GA and homocysteine (HCY), brachial-ankle pulse wave velocity (baPWV), and central systolic blood pressure (cSBP) were measured. A series of single and multiple factor analyses and stratified analysis were performed. Result The mean level of serum GA was lower in men (13.69 ± 2.69) than in women (13.82 ± 1.92) (t=2.78, P=0.005). The values of baPWV (men: F=53.9, P for trend<0.001;women:F=37.7, P for trend<0.001) and cSBP (men:F=10.3, P for trend<0.001;women:F=13.5, P for trend<0.001) increased with quartiles of GA levels in both men and women. After adjustment for age, history of hypertension, diabetes, family history of diabetes, smoking status, body mass index, waist circumference, blood pressure, blood lipids, kidney function, fasting glucose, postprandial glucose, and hemoglobin A1c, GA was positively associated with baPWV (βestimate, 0.019;95%CI:0.002-0.036;P=0.032) and cSBP (βestimate, 0.251; 95% CI: 0.107-0.394; P=0.001) in men. Stratified analysis also showed that the positive associations of GA with baPWV and cSBP remained significant in men both with and without diabetes or hypertension (P<0.05). However, the association between GA and HCY was not significant in multifactor analysis and stratified analysis. The above results were similar in women. Conclusion Serum GA levels were positively associated with baPWV and cSBP not only in patients with diabetes or hypertension but also in participants without diabetes or hypertension after adjusting for conventional factors and glucose markers. The findings suggest that GA may help detect the development of arterial stiffness in the health screening population.
