Background: Diabetes mellitus (DM) is one of the most common chronic diseases worldwide, and its prevalence has increased rapidly with economic growth. Although many researchers have previously examined the association between niacin intake and diabetes prevalence, only a few studies have evaluated the association between dietary niacin overdose and the prevalence of diabetes. Moreover, studies involving Korean subjects are scarce. The aim of this study was to determine the effect of over-consumption of niacin on the prevalence of DM.
Methods: We analyzed data derived from the 2012?2015 Korean National Health and Nutrition Survey, which included 6,548 respondents aged >45 years, who had accurately completed a questionnaire on the frequency of their food intake. Niacin overdose was defined as an intake of ≥30 mg of niacin equivalent (NE) per day and diabetes was defined as fasting blood glucose levels of ≥126 mg/dL or hemoglobin Alc of >6.5%, or based on the diagnosis made by a physician. Propensity score-matching was used for sensitivity analysis. Multivariate logistic regression analysis was performed with significant variables, adjusted to analyze the association between the prevalence of diabetes and niacin overdose.
Results: Overall, 70 individuals (64.1 weighted %) had excessive intake of niacin of ≥30 mg NE/day. Multiple logistic regression analysis after propensity score-matching revealed that inadequate niacin intake was associated with an increased prevalence of DM. The odds ratio for diabetes with inadequate niacin intake was statistically significant at 4.995 (95% confidence interval, 1.298?19.218).
Conclusion: The prevalence of DM correlated significantly with niacin overdose.
