title: Periodontitis and glycemic control in diabetes: NHANES 2009 to 2012.
abstract: BACKGROUND
  This study examines the association between periodontitis, diabetes (DM), and glycemic control.
  
  
  METHODS
  National Health and Nutrition Examination Survey data for 2009 to 2012 were analyzed. Periodontitis status of each participant was assessed using the full-mouth periodontal examination protocol, classified using the Centers for Disease Control and Prevention and the American Academy of Periodontology surveillance case definition for total periodontitis. Self-reported DM status was defined as yes or no. Glycemic control was assessed using glycohemoglobin data at cutoff points of 7.0%, 7.5%, 8.0%, 8.5%, and 9.0%. Descriptive statistics and logistic regression analyses were performed, and all analyses were adjusted for the survey design.
  
  
  RESULTS
  Overall, 7,042 adults ≥30 years old with complete data were included in the study. The mean glycohemoglobin levels for individuals with and without periodontitis were 5.9% and 5.6%, respectively, and increased to 7.4% and 7.0% for participants with DM. The majority of participants with and without periodontitis were aged 50 to 64 and 35 to 49 years (37.4% versus 44.5%), respectively. In the bivariate analysis, several demographic factors were significantly associated with having periodontitis, including self-reported DM status and glycemic control. In the multivariate analysis, demographic factors, glycohemoglobin cutoff values of 8.0%, 8.5%, and 9.0%, and mean glycohemoglobin level remained significant, but self-reported DM status was not.
  
  
  CONCLUSIONS
  This study demonstrates that glycohemoglobin and demographic factors are significantly associated with periodontitis, but not self-reported status.
