Path analysis of the factors associated with oral health literacy among community-dwelling elderly individuals: a cross-sectional study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe growing global aging population and the high prevalence of oral diseases among the elderly significantly affect their quality of life. This study aimed to assess the current status of oral health literacy (OHL) among community-dwelling elderly individuals in urban China, analyze its associated factors and theoretical pathways, and provide a scientific basis for targeted oral health interventions.
methodsBetween December 2024 and April 2025, 346 community-dwelling elderly individuals in Shenzhen were recruited via a combined snowball and convenience sampling method. OHL was measured via the simplified Chinese version of the Health Literacy in Dentistry scale (HeLD-14). Multidimensional data were collected through a structured questionnaire and analyzed via descriptive statistics, the Mann‒Whitney U test, Spearman’s correlation, multivariate linear regression, and path analysis based on structural equation modeling.
resultsThe median HeLD-14 score was 36.6 (P25-P75: 27–47), indicating a moderately low level of OHL. Multiple linear regression identified several significant predictors: education (B = 4.626, P < 0.001), monthly income (B = 2.475, P = 0.001), self-efficacy in oral health behavior (SEOH; B = 0.138, P < 0.001), social support rating scale (SSRS; B = 0.221, P < 0.001), oral health knowledge (B = 0.317, P = 0.002), and oral health attitudes (B = 0.365, P = 0.035), collectively explaining 66.3% of the variance (adjusted R² = 0.663). Path analysis revealed that education (β = 0.379, P < 0.001), SEOH (β = 0.383, P < 0.001), monthly income (β = 0.117, P < 0.001) and social support (β = 0.216, P < 0.001) were directly and positively associated with OHL. Additionally, SEOH acted as a mediator in the associations of oral health knowledge, attitudes, and social support with OHL.
conclusionThis is the first study to identify the mediating role of SEOH in relation to OHL among community-dwelling elderly individuals in urban China. OHL was found to be associated with a range of interrelated factors. Based on these associations, interventions could focus on populations with lower education and income, strengthen family and community support, and integrate oral health into chronic disease management at the community level.
