Objective:
We assessed association between periodontitis and sleep patterns.
Methods:
Our study included 7289 participants based on a large-scale study in NHANES. Periodontitis was defined through an oral examination. We used logistic regression to explore association between sleep status and risk of periodontitis. Further, stratified analysis was conducted. We performed a Mendelian randomization (MR) analysis using publicly available genetic data from corresponding studies.
Results:
Odds Ratio (OR) of periodontitis was 1.25 (1.07-1.46) in individuals with < 7 hours/per night. Stratification analysis showed individuals under 45 years old (OR: 1.28, 95% CI: 1.07-1.54), women (1.28(1.07-1.54)), education levels below high school (1.45(1.03-2.05)) and higher family income (-1.28(1.06-1.56)) were more likely to deteriorate to periodontitis if sleep time less than 7 hours. IVW-MR showed periodontitis risk was not associated with genetically increased levels of sleep time (0.22 (0.02-3.05)) or insomnia (0.83(0.55-1.24)).
Conclusion:
There was no indication that sleep status was associated with periodontitis.
