Hyperhomocysteinemia is an emerging risk factor causing early-onset cardiovascular events. The objective of the study was to assess serum homocysteine levels in newly diagnosed young persons (age < 30 years) with abnormal glucose tolerance.


This cross-sectional study included 40 young participants with newly diagnosed abnormal glucose tolerance (including prediabetes and diabetes mellitus) and an equal number of young persons with normal glucose tolerance (normal glucose tolerance vs prediabetes vs. diabetes mellitus-age (years): 25.0 (22.0, 28.0) vs 25.50 (21.50, 27.0) vs 28.0 (25.0, 29.0), median (interquartile range)). Glycemic status was diagnosed by American Diabetes Association, 2021 criteria. After taking clinical information, fasting blood was collected to measure homocysteine by chemiluminescent immunoassay.


Homocysteine level was different across the spectrum of glycemic status (normal glucose tolerance vs. prediabetes vs. diabetes mellitus: 15.57 (13.89–20.71) vs 13.19 (11.40–18.11) vs 12.27 (9.97–14.42) µmol/L; median (interquartile range); p = 0.006). Serum homocysteine was significantly elevated in participants with normal glucose tolerance than diabetes mellitus ( p = 0.006) but statistically similar in prediabetes in comparison to both normal glucose tolerance and diabetes mellitus ( p = NS for both). Homocysteine level was above the normal level in 47.5% of participants with normal glucose tolerance and in 22.5% with abnormal glucose tolerance ( p = 0.019).


Patients under 30 years with diabetes mellitus had lower homocysteine levels than those with normal glucose tolerance.
