Objectives: This study aimed to investigate the oral health-related quality of life of middle-aged and elderly in Chengdu and analyze the influencing factors.
Methods: Six hundred middle-aged and elderly people in Chengdu were randomly selected, and their demographic and social characteristics, general health status, oral health behavior, and other information were investigated. The oral health-related quality of life of these individuals was evaluated using the oral health impact profile (OHIP-14).
Results: The score of oral health-related quality of life was 3.91±6.67, and regression analysis results indicated that its influencing factors included income level (OR=0.387, P <0.05), chronic diseases (OR=0.665, P <0.05), oral diseases (OR=0.260, P <0.05), self-evaluation of mental health status (OR=0.338, P <0.05), brushing teeth twice a day (OR=1.846, P <0.05), smoking (OR=0.566, P <0.05), oral health awareness (OR=2.431, P <0.05), and convenience of medical treatment (OR=0.499, P <0.05).
Conclusions: Oral health-related quality of life is affected by multiple factors. Comprehensive oral intervention measures should be actively carried out to improve the oral health behavior of residents and oral health-related quality of life of middle-aged and elderly people in communities.
