Objectives: This study aimed to analyze the impact of health-related quality of life and oral health on depression in seniors aged 65 and older, proposing measures to improve their quality of life and prevent depression. Methods: Data from the 2022 Community Health Survey, conducted by the Korea Disease Control and Prevention Agency, were analyzed, focusing on 79,441 seniors. Results: Of the participants, 57.2% were female, and 42.8% were male. Poor oral health was associated with worse general health perception. Depression was linked to stress, suicidal thoughts, chewing discomfort, and cognitive impairment, while happiness and positive health perceptions were protective factors. Conclusions: Managing stress and enhancing positive health perceptions are key to reducing depression among the elderly.
