This study investigates the knowledge, attitudes, and practices (KAP) regarding atherosclerosis ultrasound screening among adults in the general population of Shanghai. A cross-sectional study was conducted from April 5 to May 30, 2024, at the Department of Ultrasound Medicine, Shanghai Eighth People's Hospital, involving the general public. An investigator-designed questionnaire collected demographic information and KAP scores. Path analysis was performed to assess the relationships between overall KAP scores, with subgroup analysis for participants with atherosclerotic cardiovascular disease (CVD). A total of 617 valid questionnaires were analyzed, revealing a high reliability coefficient of 0.949. Mean KAP scores were as follows: knowledge 9.73 ± 5.80 (/24, 40.54%), attitude 56.38 ± 10.94 (/65, 86.74%), and practice 21.66 ± 5.54 (/35, 61.89%), indicating poor knowledge but positive attitudes and proactive practices. Knowledge significantly influenced both attitude (β = 0.354, P = 0.028) and practice (β = 0.357, P = 0.021). In participants with CVD, mean scores were 11.14 ± 4.10 for knowledge, 59.69 ± 11.94 for attitude, and 23.17 ± 5.32 for practice. In the general Shanghai population, knowledge about atherosclerosis ultrasound screening is poor, yet attitudes are positive, and practices are proactive. Targeted educational interventions are necessary to enhance knowledge and attitudes, thus improving screening practices.
本研究调查了上海普通人群中成年人对动脉粥样硬化超声筛查的知识、态度和实践（KAP）情况。2024年4月5日至5月30日，在上海市第八人民医院超声医学科对普通公众进行了一项横断面研究。由研究者设计的问卷收集了人口统计学信息和KAP评分。进行路径分析以评估总体KAP评分之间的关系，并对患有动脉粥样硬化性心血管疾病（CVD）的参与者进行亚组分析。共分析了617份有效问卷，可靠性系数高达0.949。KAP平均得分如下：知识9.73±5.80（/24，40.54%），态度56.38±10.94（/65，86.74%），实践21.66±5.54（/35，61.89%），表明知识水平较差，但态度积极且实践主动。知识对态度（β = 0.354，P = 0.028）和实践（β = 0.357，P = 0.021）均有显著影响。在患有CVD的参与者中，知识平均得分为11.14±4.10，态度平均得分为59.69±11.94，实践平均得分为23.17±5.32。在上海普通人群中，关于动脉粥样硬化超声筛查的知识较差，但态度积极，实践主动。需要有针对性的教育干预措施来提高知识水平和态度，从而改善筛查实践。
