To explore the relationship between oral health-related quality of life (OHRQoL) and dental care-seeking behavior among the elderly in Sichuan Province, while analyzing the impact of income on this relationship.
A total of 744 elderly individuals aged 65 to 74 years from Sichuan Province were included in this study through multi-stage stratified random sampling during the Fourth National Oral Health Epidemiological Survey conducted from 2015 to 2016. A questionnaire was used to assess the participants’ income levels, dental care-seeking behavior, and OHRQoL. Stratified logistic regression was employed to examine the relationship between dental care-seeking behavior and OHRQoL, as well as the moderating effect of income.
Among the 744 participants, 552 (74.2%) reported engaging in dental care-seeking behavior. Lower overall (β=-0.040, P < 0.001), functional (β=-0.028,P=0.002), pain-related (β=-0.037, P < 0.001), and psychological (β=-0.029, P=0.002) dimensions of OHRQoL were associated with an increased likelihood of dental care-seeking among the elderly. Additionally, income had a positive moderating effect only on the relationship between oral health-related psychological discomfort and dental care-seeking behavior; specifically, lower income was associated with a weaker correlation between psychological discomfort related to oral health and dental care-seeking behavior (β=-0.007,P=0.039).
The utilization of oral health services among the elderly in Sichuan Province is suboptimal, with poor OHRQoL being a primary driving factor for dental care-seeking behavior. High income only facilitates dental visits when oral health issues lead to psychological discomfort. Public health efforts targeting oral health among the elderly should focus on updating their perceptions of oral health and addressing the psychological impacts associated with oral health.
