摘要目的:了解苏州市孕妇人群流感及流感疫苗的知识、态度和行为（KAP）现状，分析其影响因素，为推动孕妇人群流感疫苗接种的公共卫生策略提供支撑。方法:采用分层抽样的方法，对2023年在苏州市不同等级医疗机构接受体检的不同妊娠期的孕妇进行面对面调查，分析其KAP现状，并采用 χ2检验和logistic回归进行影响因素分析。 结果:本研究共回收有效问卷2 195份。苏州市孕妇人群流感和流感疫苗相关知识的得分 M（ Q1， Q3）为7.60（5.23，9.80）分，得分范围为0.20~14.71分，及格率为34.12%，流感疫苗的知晓率为57.45%，过去1年接种过流感疫苗者占1.91%，妊娠期有流感疫苗接种意愿者占3.57%。有关流感和流感疫苗相关知识得分的多因素分析显示，及格率与文化程度、孕周及家庭年收入呈正相关，居住在农村地区、职业为农民工、无医保与及格率呈负相关，接种意愿的多因素分析显示，流感疫苗有效性降低、不良反应增多会降低妊娠期的接种意愿。 结论:苏州市孕妇人群对流感的关注度较高，妊娠期接种率和接种意愿普遍较低。早、中妊娠期、低文化程度、居住在农村地区、职业为农民工以及无医保的孕妇是普及流感和流感疫苗相关知识的重点人群。

abstractsObjective:To understand the current knowledge, attitude, and practice (KAP) on influenza and influenza vaccine among pregnant women in Suzhou and to analyze its influencing factors to provide technical support data for public health strategies for promoting influenza vaccination in pregnant women.Methods:A questionnaire was designed, and a stratified sampling method was used to conduct a face-to-face survey among pregnant women at different stages of pregnancy who received antenatal examinations at different levels of medical institutions in Suzhou, Jiangsu Province, in 2023. KAP status and influencing factors were analyzed by χ2 test and logistic regression analysis. Results:A total of 2 195 valid questionnaires were collected in this survey. The M( Q1, Q3) of knowledge about influenza and influenza vaccine among pregnant women in Suzhou was 7.60 (5.23, 9.80) points, and the score range was 0.20-14.71 points, the passing rate was 34.12%, the awareness rate of influenza vaccine was 57.45%, and the vaccination rate of influenza vaccine was 1.91% within one year before the survey. The willingness to receive influenza vaccine during pregnancy was only 3.57%. Multivariate analysis of influenza and influenza vaccine-related knowledge scores showed that the passing rate was positively correlated with education level and gestational age. In contrast, family income was negatively correlated with living in rural areas, working as migrant workers, and having no medical insurance. Multivariate analysis of vaccination intention showed that decreased effectiveness of influenza vaccine and increased adverse reactions decreased vaccination intention during pregnancy. Conclusions:The pregnant women in Suzhou pay more attention to influenza, and vaccination rates and intentions are generally low. Pregnant women with early and second trimester of pregnancy, low education, living in rural areas, working as migrant workers, and not purchasing medical insurance are the key groups to popularize the knowledge about influenza and influenza vaccine.
