No association between glucose at age 30 and aortic diameter at age 65 in men: a population-based study

Impaired glucose metabolism and diabetes mellitus has been linked to a decreased risk for abdominal aortic aneurysm development in men. We evaluated potential relationships between blood glucose levels in 1722 men with mean age 34 years and their aortic diameter measured by ultrasound at age 65 years.

Prospective cohort study.

Mean follow-up between baseline glucose investigation and aortic ultrasound was 32.8 ± 1.8 years. There was no correlation between baseline blood glucose and later aortic diameter (r = 0.035, p = 0.146), whereas a weak correlation between body mass index (BMI) and aortic diameter was observed (r = 0.097 p < 0.001). In a partial correlation between aortic diameter and glucose levels adjusted for BMI, the correlation did not change (r = 0.011, p = 0.66). Neither were there any significant differences in mean aortic diameter between men belonging to different quartiles of baseline blood glucose levels (19.5, 19.1, 19.6 and 19.7 mm, p = 0.18).

Fasting blood glucose in 33-year-old men was not associated with their aortic diameter at age 65 years. Potential pathophysiological processes linking disturbed glucose metabolism to a decreased risk for development of abdominal aortic aneurysm in men are therefore probably not relevant until later in life.
