The association between sedentary behavior and obstructive sleep apnea: a cross-sectional study from the NHANES (2007-2008 to 2015-2020).

Background: Sedentary behavior (SB) may contribute to obesity and lower extremity fluid retention, which may favor the development of obstructive sleep apnea (OSA). However, linking sedentary behavior to OSA is unclear. The purpose of this study was to determine if there is an association between SB and OSA.

Heel bone mineral density and various oral diseases: a bidirectional Mendelian randomization.

Introduction: Observational studies demonstrated that the relationship between bone mineral density and oral diseases is mixed. To access the association between heel bone mineral density and various oral diseases, we conducted the Mendelian randomization analysis to explore the association.

Materials And Methods: Two-sample bidirectional Mendelian analysis was used to explore the relationship between heel bone mineral density and various oral diseases.
