Abstract
Objectives: Periodontitis is a common chronic disease affecting nearly half of adults in the United States. Sleep problems have been increasingly recognized as serious public health problems that may have negative effects on health. While it is plausible that sleep problems may negatively influence periodontal health, there is paucity of research on this topic. Therefore, we aim to investigate the association between sleep problems and periodontitis among US adults.
Method: This study analyzed the data from 3,743 participants who were surveyed between 2009 and 2010 as a part of the National Health and Nutritional Examination Survey (NHANES). Participants who underwent periodontal examinations and had completed the sleep habits questionnaire were included in the study. Subjects were categorized into short sleepers ([less than] 6 hrs.), average sleepers (7-8 hrs.), and long sleepers (2-9 hrs.) based on how much sleep an individual got at night, and into three sleep problems groups based on the answers to two self-reported sleep disorder questions: diagnosed sleep disorders, having trouble sleeping, and no sleep problems. The Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC/AAP) case definition for moderate or severe periodontitis was used as a final outcome. Analyses were conducted using the Rao-Scott Chi-Square test and logistic regression modeling taking into account the complex sampling design of the survey to obtain unbiased estimates and variance.
Results: The odds ratio (OR, 95% Confidence Interval (CI)) of having periodontitis among short sleepers was 1.19 (95% CI= 1.02 - 1.40) compared to average sleepers. Having sleep disorders was only associated with an increased likelihood of having periodontitis (OR =1.44, 95% CI=1.11-1.89) among subjects [greater than] 50 years. Additionally, among all adults, a significant association was observed when sleep disorders were combined with short sleep (OR=l.50; 95% CI= 1.03-2.44). The strongest association was found when sleep disorders were combined with short sleep among adults [greater than] 50 years of age (OR, 1.77; 95% CI= 1.05-3.00).
Conclusion: Our population based study revealed that sleep problems may be risk indictors for periodontitis. Further studies are needed to better understand the complex interplay between sleep problems and periodontitis.
