Abstract
The purpose of this study is to determine whether the lower intakes of yogurt, milk, and calcium are associated with periodontitis in a nationally representative sample of Korean adults. This study comprised 6,150 adults 19 or more years old who took both periodontal examination and nutrition survey. The frequency of yogurt and milk intake was examined with a food frequency questionnaire. The amount of calcium intake was calculated with dietary intakes data gained from complete one-day 24-hour recall interviews. Periodontitis was assessed using the Community Periodontal Index (CPI). Multivariate logistic regression analyses were performed for the whole sample and subgroups with the strata of age, gender, or smoking, in a complex sampling design. Less intake of yogurt was significantly associated with periodontitis (odds ratio [OR] 0.82, 95% confidential interval [CI] 0.70–0.97), but neither less intake of milk (OR 1.04, 95% CI 0.89–1.20) nor lower intake of calcium (OR 1.04, 95% CI 0.89–1.21) was significantly associated with periodontitis. In the subgroup analysis, no difference in the association of yogurt intake with periodontitis was found according to the strata of age, gender, and smoking. In conclusion, periodonitis was significantly associated with the less intake of yogurt among the Korean adults, but the calcium contained in yogurt is not likely to cause it.
Highlights
Periodontitis is a chronic inflammatory disease that leads to destruction of the connective tissue and alveolar bone around teeth [1]
The data used in this study are a subset of the fourth Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2009 by Korea Centers for Disease Control and Prevention (KCDC) [17]
The prevalence of periodontitis defined as a Community Periodontal Index (CPI) code ! 3 was 30.8% in adults over the age 19 years (n = 6,150)
Summary
Periodontitis is a chronic inflammatory disease that leads to destruction of the connective tissue and alveolar bone around teeth [1]. Due to its high prevalence in adults, it is a major cause of teeth extraction in adults and represents one of the important public health problems that increase the burden of chronic diseases in many countries [2, 3]. Several factors were suggested as risk factors of periodontitis such as smoking and diabetes [5,6]. Diet and lower intake of various nutrients were suggested as potential risk factors for periodontitis [7, 8]. In 2006, Al-Zahrani [10] proposed a novel hypothesis that dairy food intake might be inversely associated with periodontitis.
