Periodontitis and intake of thiamine, riboflavin and niacin among Korean adults.

Objectives: Adequate intake of vitamin B complex could be prerequisite to health. However, few studies have been reported on the association of thiamine (vit B ), riboflavin (vit B ) and niacin (vit B ) with periodontal health. This study described the association between periodontal health and dietary vit B , vit B and vit B intake in the Korean population.

Methods: A total of 12 750 adults aged over 19 years were selected for this study as a sub-sample of the national data set from Korean National Health and Nutrition Examination Survey (IV and V). Periodontitis and gingivitis were defined as Community Periodontal Index (CPI) scores of 3-4 and 1-2, respectively. Information on dietary vit B , vit B and vit B intake was from 24-hour dietary recall method. Multivariable complex logistic regression analyses estimated association between vit B , vit B and vit B intakes and periodontal health after adjusting for various potential confounders. Stratified analyses by age, sex, dyslipidemia and total energy intake were also undertaken.

Results: The overall estimated prevalence of periodontitis (CPI 3-4) and gingivitis (CPI 1-2) was 29.9% and 46.6%, respectively. Our data showed none of the inadequate intake of vit B , vit B and B showed significant association with gingivitis after adjusting for potential confounders. Inadequate intake of vit B showed higher prevalence odds of periodontitis by 1.25 times (adjusted odds ratio = 1.25, 95% CI = 1.07-1.46). The association of vit B with periodontitis was stronger in females and participants aged 40-59 years.

Conclusions: Inadequate dietary intake of vit B was associated with periodontitis.
