Examining the Impact of Natural Teeth Trajectory on Mortality Among CLHLS.

ABSTRACT:

Background

To investigate the associations between trajectories of the number of natural teeth and all-cause mortality among Chinese middle-aged and older adults.

Methods

Data for this study were sourced from the 2002, 2005, 2008, 2011, 2014, and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). The number of natural teeth was assessed through self-reports. Population-based trajectory models were utilised to explore potential heterogeneity in longitudinal changes over 16 years and to examine the associations between baseline predictors and different trajectories among cohort members. Additionally, the Cox proportional hazards model was employed to assess the risk factors associated with these trajectories.

Results

Three distinct trajectories in
