OBJECTIVE: This study aimed to investigate the association between general physical activity level and TMD pain in Koreans in a large-scale national database established through a nationwide survey.
METHODS: Data from the Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV), which was conducted from 2007 to 2009, were analysed. In total, 16 941 participants were included in this cross-sectional study. Data on sociodemographic characteristics, TMD-related variables, and general physical activity level were collected. Participants were divided into moderate- and low-intensity exercise groups according to their physical activity levels. Multivariate logistic regression analyses were performed, adjusting for sociodemographic and other covariates.
RESULTS: The adjusted odds ratio (OR) (95% confidence interval; CI) for TMD pain was 1.373 (1.017-1.854) for people doing moderate-intensity exercises and 0.797 (0.629-1.008) among people doing low-intensity exercises. Those who did moderate-intensity exercises had significantly more TMD pain. This was higher in the 30- to 39-year age group (OR: 1.991, 95% CI: 1.137-3.488), with significantly higher risk for TMD pain in those who did moderate-intensity exercise, whereas low-intensity exercise significantly decreased the risk for TMD pain in the same age group (OR: 0.625, 95% CI: 0.409-0.958).
CONCLUSIONS: Moderate-intensity physical activity is associated with more TMD pain. Patients with TMD should avoid high-intensity level exercises and continue low-intensity exercises to prevent pain aggravation.
