南京市大学生对细颗粒物污染影响呼吸系统健康的知信行调查OA
A survey on the knowledge,attitudes,and practices of college students in Nanjing regarding the impact of fine particulate matter pollution on respiratory health
目的:探究南京市大学生关于细颗粒物(fine particulate matter,PM2.5)污染及其对呼吸系统健康影响的知信行(knowledge,attitudes,and practices,KAP)现状,为大学生呼吸系统健康教育提供理论与实践指导.方法:招募2024年8-11月南京市550名在校大学生作为研究对象,采用在线调查问卷形式,针对PM2.5污染影响呼吸系统健康KAP开展调查.结果:在451份完整有效调查问卷中,PM2.5相关知识得分正确率仅为43.53%,呼吸系统健康知识得分正确率仅为40.30%,态度平均得分3.38分(总分4分),行为平均得分3.00分(总分4分).多元线性回归分析显示,经济水平(生活开销、家庭收入)正向影响知识和行为评分(β=0.283,P<0.01),而家族病史对知识评分起负效应(β=-0.108,P<0.05).经济水平(生活开销、家庭收入)正向影响知识(β=0.162,P<0.01)和行为评分(β=0.283,P<0.01).结构方程模型(structural equation model,SEM)证实知识、态度[标准化路径系数(standardized path coefficients,SPC=0.270,P<0.01)]、行为(SPC=0.148,P<0.01)的显著因果传递效应,并识别出42条显著的影响路径关系,但部分知识条目与行为呈负相关,提示情境因素(如生活压力、时间紧张等)抑制行为转化.结论:南京市大学生对PM2.5污染及其对呼吸系统健康影响的认识与应对措施整体薄弱.应基于大学生专业背景、家庭收入、年龄等因素,开展针对性PM2.5防治知识普及与呼吸系统健康教育,通过多主体协同干预促进大学生KAP的有效转化.
Objective:To investigate the knowledge,attitudes,and practices(KAP)of college students in Nanjing regarding fine particulate matter(PM2.5)pollution and its impact on respiratory health,providing theoretical and practical guidance for respiratory health education.Methods:From August to November 2024,550 college students in Nanjing were recruited as study participants.An online questionnaire survey was conducted to assess KAP related to PM2.5 pollution and respiratory health.Results:Among 451 valid responses,the accuracy rates of PM2.5-related knowledge and respiratory health knowledge were only 43.53%and 40.30%,respectively.The mean attitude score was 3.38(out of a total of 4),while the mean behavior score was 3.00(out of a total of 4).Multiple linear regression analysis revealed that economic status(monthly expenditure,household income)positively influenced knowledge(β=0.162,P<0.01)and behavior scores(β=0.283,P<0.01),whereas family history of respiratory diseases negatively affected knowledge scores(β=-0.108,P<0.05).The structural equation model(SEM)confirmed the significant causal transmission effect of knowledge,attitude[standardized path coefficients(SPC)=0.270,P<0.01],and behavior(SPC=0.148,P<0.01).A total of 42 significant influence pathways were identified,though some knowledge components including respiratory protection exhibited negative associations with behavior,suggesting that contextual factors such as life stress and time constraints may hinder behavioral adoption.Conclusion:The awareness and countermeasures of PM2.5 pollution and its impact on respiratory health among college students in Nanjing City are generally weak.Respiratory health education based on factors such as university students'professional background,family income and age,targeted popularization of PM2.5 prevention and control knowledge and should be carried out,and the effective transformation of college students'knowledge,attitude,and behavior should be promoted through multi-subject collaborative intervention.
