Abstract

Background: Niacin increases blood glucose, but whether the degree of increase is associated with increasing body mass index (BMI) is unknown. We evaluated the effect of extended-release niacin initiation on fasting plasma glucose (FPG) and the development of new-onset diabetes mellitus (DM) in relation to body mass index (kg/m2) in nondiabetic patients. Methods: This retrospective observational study used data from six facilities within a geographical region of the Department of Veterans Affairs (VA). Patients included were 18 years of age or older and on a stable extended-release niacin dose (minimum 100 days) of at least 250 mg/day between January, 2001, and April, 2007. Patients were excluded if they were new to the VA, on corticosteroids or insulin, if medication adherence was <80%, or if they met criteria for DM. Results: A total of 811 nondiabetic patients taking extended-release niacin initiation were studied. FPG after niacin initiation was stastically significantly correlated with increasing BMI (P < 0.001, R = 0.144 Pearson correlation coefficient). Factors independently associated with change in FPG using multiple linear regression were BMI (P = 0.043), baseline average glucose (P < 0.001), and baseline average triglycerides (P = 0.037). Of all patients started on niacin, 220 (27.1%) patients developed DM after niacin initiation. BMI, (P = 0.002) and baseline average glucose (P < 0.001) were independent predictors of the development of new-onset DM (logistic regression analysis). Conclusions: We found an association between increasing BMI and increasing FPG and diagnosis of new-onset DM after initiation of extended-release niacin initiation. This suggests that extended-release niacin may increase FPG into the diabetic range, especially for obese patients
