Data from Seoul National University Provide New Insights into Periodontitis (The association of dietary vitamin C intake with periodontitis among Korean adults: Results from KNHANES IV)

By a News Reporter-Staff News Editor at China Weekly News -- Investigators publish new report on Periodontal Diseases and Conditions - Periodontitis. According to news reporting out of Seoul, South Korea, by VerticalNews editors, research stated, "The association of dietary vitamin C (vit C) on periodontitis requires more valid evidence from large representative samples to enable sufficient adjustments. This study aimed to evaluate the association between dietary vit C intake and periodontitis after controlling for various confounders in the representative Korean adult population."

Financial support for this research came from National Research Foundation of Korea (KR).

Our news journalists obtained a quote from the research from Seoul National University, "A total of 10,930 Korean adults ( greater than or equal to19 years) from the fourth Korean National Health and Nutrition Examination Survey data set were included in this cross-sectional study. Periodontitis was defined as community periodontal index score of 3 or 4. Dietary vit C intake was estimated from a 24-hour dietary record, and categorized into adequate and inadequate according to the Korean Estimated Average Requirement value. Potential confounders included age, sex, income, frequency of tooth brushing, use of floss, dental visit, drinking, smoking, diabetes, hypercholesterolemia, hypertension, and obesity. A multivariable logistic regression analysis and stratified analysis were applied. Those with inadequate dietary vit C intake were more likely by 1.16 times to have periodontitis than those with adequate dietary vit C intake (adjusted odds ratio [aOR]=1.16, 95% confidence interval=1.04-1.29). Lowest and middle-low quartile of dietary vit C intake, compared to highest quartile of dietary vit C intake, showed significant association (aOR=1.28 and 1.22 respectively), which was in a biological-gradient relationship (trend-p <0.05). Our data showed that inadequate dietary vit C intake was independently associated with periodontitis among Korean adults."

According to the news editors, the research concluded: "Hence, adequate intake of dietary vitamin C could be substantially important on the promotion of periodontal health among Korean adults."
