【摘要】 目的 了解贵州省中老年人口腔健康知信行现状，评估其影响因素，为中老年群体口腔健康促进策略提供参考依据。方法 采用多阶段分层整群随机抽样方法抽取贵州省35～44岁中年人2 040人，65～74岁老年人2 023人。使用χ~2检验和非参数检验分析知信行现状，Spearman检验分析知信行的相关性，负二项回归模型分析知信行的相关因素。结果 知识知晓率与态度持有率低于全国平均水平，进食甜食频率低于全国平均水平。知识与态度、口腔清洁行为呈正相关（r=0.511、0.174），态度与口腔清洁行为呈正相关（r=0.140）。经多因素调整后发现，性别、年龄、经济地区、教育年限及医保类型是知识知晓和积极态度持有情况的影响因素；饮食行为得分与女性（OR=1.015,95%CI:1.002～1.028）、65～74岁（OR=1.038,95%CI:1.024～1.052）、教育年限≤9年（OR=1.099,95%CI:1.052～1.149）、农村（OR=1.051,95%CI:1.028～1.075）呈正向关系，与三类地区（OR=0.971,95%CI:0.944～0.998）呈负向关系；口腔清洁行为得分与女性（OR=1.087,95%CI:1.056～1.119）、三类地区（OR=1.080,95%CI:1.012～1.152）呈正向关系，与65～74岁（OR=0.930,95%CI:0.902～0.959）、农村（OR=0.929,95%CI:0.879～0.981）、居民医保（OR=0.852,95%CI:0.816～0.890）呈负向关系。结论贵州省中老年人群口腔健康知信行水平具有独特特征，有必要通过开发适老化宣教，优化口腔疾病保险政策等措施促进知识、态度、行为合理转化。更多还原

【Abstract】 Objective To investigate the current status of oral health knowledge, attitudes and practices(KAP) of middle-aged and elderly populations in Guizhou Province, to identify their influencing factors, and to provide a reference basis for oral health promotion strategies among middle-aged and elderly populations. Methods A multistage stratified cluster random sampling method was employed to select 2 040 middle-aged people aged 35-44 years and 2 023 elderly people aged 65-74 years. The χ~2 test and non-parametric test were used to analyse status of oral health KAP. The Spearman test was used to assess their correlations, while a negative binomial regression model was applied to examine associated factors. Results Levels of knowledge and attitudes were lower than the national average, and the frequency of consuming sweets was lower than the national average. Knowledge was positively correlated with attitudes and oral hygiene practices(r=0.511, r=0.174),and attitudes were positively correlated with oral hygiene practices(r=0.140). After adjustment for multiple variables, gender,age, economic region, education, and type of health insurance were identified as significant factors influencing knowledge and positive attitudes. Dietary behaviour scores were associated with females(OR=1.015, 95% CI: 1.002-1.028), those aged 65-74(OR=1.038, 95% CI: 1.024-1.052), those with ≤9 years of education(OR=1.099, 95% CI: 1.052-1.149), and rural residents(OR=1.051, 95% CI: 1.028-1.075), while negatively associated with residents in Category III regions(OR=0.971,95% CI: 0.944-0.998). Oral hygiene behaviour scores showed a positive association with female gender(OR=1.087, 95% CI:1.056-1.119) and Category III regions(OR=1.080, 95% CI: 1.012-1.152), and a negative association with those aged 65-74(OR =0.930, 95% CI: 0.902-0.959), rural residents(OR =0.929, 95% CI: 0.879-0.981), and residents with basic medical insurance(OR=0.852, 95% CI: 0.816-0.890). Conclusion The level of oral health knowledge, attitudes and practices of the middle-aged and elderly populations in Guizhou Province has distinctive characteristics. Strengthening age-appropriate health education and optimizing oral disease insurance policies are essential to promote the effective translation of knowledge and attitudes into positive health practices among middle-aged and elderly populations.更多还原
