Distal and Proximal Influences on Self-Reported Oral Pain and Self-Rated Oral Health Status in Saudi Arabia: Retrospective Study Using a 2017 Nationwide Database

Abstract

Background: Oral health significantly influences overall well-being, health care costs, and quality of life. In Saudi Arabia, the burden of oral diseases, such as dental caries and periodontal disease, has increased over recent decades, driven by various lifestyle changes.

Objective: To explore the associations between proximal (direct) and distal (indirect) influences that affect oral pain (OP) and self-rated oral health (SROH) status in the Kingdom of Saudi Arabia (KSA) using an adapted conceptual framework.

Methods: This retrospective cross-sectional study used data from a national health survey conducted in KSA in 2017. The sample included adults (N=29,274), adolescents (N=9910), and children (N=11,653). Sociodemographic data, health characteristics, and access to oral health services were considered distal influences, while frequency and type of dental visits, tooth brushing frequency, smoking, and consumption of sweets and soft drinks were considered proximal influences. Path analysis modeling was used to estimate the direct, indirect, and total effects of proximal and distal influences on OP and SROH status.

Results: The mean age of adult respondents was 42.2 years; adolescents, 20.4 years; and children, 10.58 years. Despite OP reports from 39% of children, 48.5% of adolescents, and 47.1% of adults, over 87% across all groups rated their oral health as good, very good, or excellent. A higher frequency of tooth brushing showed a strong inverse relationship with OP and a positive correlation with SROH (P<.001). Frequent dental visits were positively associated with OP and negatively with SROH (P<.001). Sweet consumption increased OP in adolescents (β=0.033, P=.007) and negatively affected SROH in children (β=-0.086, P<.001), adolescents (β=-0.079, P<.001), and adults (β=-0.068, P<.001). Soft drink consumption, however, was associated with lower OP in adolescents (β=-0.034, P=.005) and improved SROH in adolescents (β=0.063, P<.001) and adults (β=0.068, P<.001). Smoking increased OP in adults (β=0.030, P<.001). Distal influences like higher education were directly linked to better SROH (β=0.046, P=.003) and less OP (indirectly through tooth brushing, β=-0.004, P<.001). For children, high household income correlated with less OP (β=-0.030, P=.02), but indirectly increased OP through other pathways (β=0.024, P=.003). Lack of access was associated with negative oral health measures (P<.001).

Conclusions: Among the KSA population, OP and SROH were directly influenced by many proximal and distal influences that had direct, indirect, or combined influences on OP and SROH status.
