Mediating effect of health literacy on the relationship between social support and treatment compliance of periodontal disease patients

摘要:
目的 牙周病作为常见慢性口腔疾病,其治疗效果高度依赖患者长期规范的治疗依从性,本研究旨在探讨健康素养在社会支持与牙周病患者治疗依从性间的中介效应,揭示社会支持影响患者治疗依从性的潜在作用路径,为临床制定针对性干预措施、提升牙周病患者治疗依从性及改善预后提供理论依据。 方法 选取2023年4月—2025年4月在温州医科大学附属口腔医院接受治疗的220例牙周病患者,采用一般资料问卷、健康素养量表、社会支持量表及治疗依从性量表,分别收集患者的一般人口学信息、健康素养水平、社会支持状况及治疗依从性情况。采用Pearson相关分析探讨健康素养、社会支持与治疗依从性之间的相关性;进一步通过结构方程模型与Bootstrap法(5 000次抽样)构建中介效应模型,分析健康素养在社会支持与治疗依从性之间的中介作用。 结果 最终纳入有效样本212例,有效回收率为96.36%。健康素养、社会支持、治疗依从性间呈两两正相关关系(P < 0.05);中介效应模型显示:社会支持可直接影响治疗依从性,也可通过健康素养间接影响治疗依从性(P < 0.001);健康素养在社会支持与治疗依从性之间的中介效应占总效应的38.25%(0.210/0.549)。 结论 牙周病患者治疗依从性受多个因素影响,健康素养在牙周病患者家庭社会支持与治疗依从性间起部分中介作用。 Abstract:Objective Periodontal disease, as a prevalent chronic oral condition, requires long-term standardized treatment adherence from patients for optimal therapeutic outcomes. This study aims to explore the mediating effect of health literacy on the relationship between social support and treatment compliance in patients with periodontal disease, in order to reveal the underlying pathways through which social support influences adherence. The findings are expected to provide a theoretical basis for developing targeted clinical interventions, enhancing treatment compliance, and improving prognosis in this patient population. Methods From April 2023 to April 2025, 220 patients with periodontal disease received treatment at the Affiliated Stomatology Hospital of Wenzhou Medical University. The study collected general demographic information, health literacy levels, social support status, and treatment adherence using a general data questionnaire, health literacy scale, social support scale, and treatment adherence scale. Pearson correlation analysis was employed to explore the relationships between health literacy, social support, and treatment adherence. Furthermore, a structural equation model and Bootstrap method (with 5 000 bootstrap samples) were used to construct a mediation effect model, analyzing the mediating role of health literacy between social support and treatment adherence. Results A total of 212 valid samples were ultimately included, with a recovery rate of 96.36%. There was a positive correlation between health literacy, social support, and treatment compliance (P < 0.05). The results of the mediation effect model showed that social support could directly influence treatment adherence and could indirectly influence treatment adherence through health literacy (P < 0.001). The mediation effect of health literacy between social support and treatment adherence accounted for 38.25% of the total effect (0.210/0.549). Conclusion The treatment compliance of periodontal disease patients is affected by many factors, and health literacy plays a partial mediating role between family social support and treatment compliance of periodontal disease patients. -
