청소년의 스마트폰 사용이 구강건강행태에 미치는 영향 : 수면과 스트레스의 매개효과를 중심으로
The effects of smartphone use on oral health behaviors among adolescents : focusing on the mediating effects of sleep and stress
Purpose: This study aimed to examine the association between smartphone use time and oral health behaviors among Korean adolescents and to investigate the mediating effects of mental health factors. Methods: Data from the 2025 Korea Youth Risk Behavior Survey (n=52,385) were analyzed. Smartphone use time was used as the independent variable, and the oral health behavior index (0~5) was used as the dependent variable. Multiple regression and bootstrap mediation analyses were conducted. Results: Longer smartphone use duration was significantly associated with poorer oral health behavior (β=–0.095, p<0.001). Adolescents with higher levels of smartphone use showed lower rates of tooth brushing, flossing, scaling, and dental check-ups. Stress, sleep insufficiency, and depressive experience exerted significant partial mediating effects, with depressive experience demonstrating the strongest indirect effect. Conclusion: Excessive smartphone use negatively affects oral health behaviors directly and indirectly through mental health factors.
