Sleep bruxism and daily life behaviors in university students: a cross-sectional analysis of free time management, sedentary behaviors, and smartphone use
Cross-sectional analysis reveals links between sleep bruxism, smartphone addiction, and TMD severity in university students, indicating lifestyle implications.
Key Points
This study aims to explore the relationship between sleep bruxism and various lifestyle factors among university students.
Conducted a cross-sectional analysis with 113 university students.
Used the Fonseca Anamnestic Index (FAI) for screening sleep bruxism.
Assessed free time management with the Free Time Management Scale (FTMS), sedentary behaviors with the Sedentary Behavior Questionnaire (SBQ), and smartphone addiction with the Smartphone Addiction Scale-Short Version (SAS-SV).
Employed independent samples t-tests and Pearson Chi-square tests for statistical comparisons.
No significant differences in total free time management scores or sedentary behaviors between sleep bruxers and non-bruxers.
The sleep bruxism group displayed significantly higher smartphone addiction scores (30.94 ± 10.03) compared to the non-bruxer group (27.25 ± 8.68) with p = 0.04.
A strong positive association was found between sleep bruxism and the severity of temporomandibular disorders (p < 0.001).
Students with sleep bruxism were 10.9 times more likely to report moderate-to-severe symptoms of temporomandibular disorders compared to non-bruxers.
