Background: Micronutrients play an important role in the development, progression, and complications of diabetes mellitus (DM). Specifically, vitamin C appears to be associated with DM, although its precise role remains unclear. The purpose of this study was to determine the association between vitamin C intake and DM.
Methods: The data for this study were obtained from the Korean National Health and Nutrition Examination Survey 2012?2015. A total of 6,548 individuals (2,542 men and 4,006 women) were involved in this analysis. The participants were divided into two groups according to daily vitamin C intake. The first group included participants ingesting ≥90 mg/day of vitamin C per day. The second group included participants ingesting ＜90 mg/day of vitamin C per day, which is lower than the recommended daily dose. Logistic regression analysis was performed to determine the association between vitamin C intake and DM.
Results: Overall, 2,801 (44.9 weighted %) individuals had an inadequate intake of vitamin C of ＜90 mg/day. Multiple logistic regression analysis revealed that male sex, age, waist circumference, family income, hypertension, and dyslipidemia were associated with an increased prevalence of DM. The odds ratio for DM with inadequate vitamin C intake was 1.41 (95% confidential interval [CI], 1.72?1.70) and this was statistically significant.
Conclusion: Inadequate daily vitamin C intake (＜90 mg/day) is associated with an increased prevalence of DM.
