After 3 years, 9·3% of subjects developed IFG (<italic>n </italic>=<italic> </italic>56). Age, gender, BMI and fasting glucose were used to match the remaining NFG subjects (<italic>n </italic>=<italic> </italic>546) that were included for the control group (NFG group, <italic>n </italic>=<italic> </italic>80).</p> </sec> <sec id="cen12821-sec-0003" sec-type="section"> <title>Results</title> <p>After 3 years, levels of fasting glucose, insulin and malondialdehyde, and brachial–ankle pulse wave velocity (baPWV) were significantly greater in the IFG group than in the NFG group after adjusting for baseline values. The IFG group had a greater increase in lactosylceramide (<italic>P </italic>=<italic> </italic>0·001, <italic>q </italic><<italic> </italic>0·05) and a greater reduction in phosphatidylcholine (PC) (18:0/20:4) than the NFG group. Multiple linear regression analysis showed that the change in baPWV was independently and positively associated with changes in fasting glucose and lactosylceramide. In all subjects, lactosylceramide levels positively correlated with changes in baPWV and fasting glucose, while premenopausal women were not shown, and negatively correlated with changes in PC and LDL particle size.</p> </sec> <sec id="cen12821-sec-0004" sec-type="section"> <title>Conclusions</title> <p>This study indicates that age‐related increase in circulating lactosylceramide is an independent predictor of increased arterial stiffness in subjects with impaired fasting glucose.</p> </sec> </abstract>
