Several obstacles can hinder breast cancer screening. This study aimed to investigate the knowledge, attitude, and practice (KAP) toward ultrasound screening for breast cancer in women.
This cross-sectional study recruited women who visited the breast specialist clinic of Zhongshan City People's Hospital (a tertiary hospital) between August 2022 and April 2023 through convenience sampling. KAP scores ≥70% were considered adequate.
This study enrolled 501 participants. The mean knowledge, attitude, and practice levels were 8.56 ± 1.81/12 (possible range 0-12, 71.33%), 29.80 ± 2.71 (possible range 8-40, 74.50%), and 32.04 ± 3.09 (possible range 8-40, 80.10%). Senior high school education (vs. junior high school and below, coefficient = 1.531, 95%CI: 1.013-2.312, = 0.044), bachelor's education and above (vs. junior high school and below, coefficient = 5.315, 95%CI: 3.546-7.966, < 0.001), housewife or unemployed (vs. employed, coefficient = 0.671, 95%CI: 0.466-0.966, = 0.032), and a history of breast ultrasound (vs. no, coefficient = 1.466, 95%CI: 1.121-1.917, = 0.005) were independently and positively associated with knowledge. Knowledge (coefficient = 1.303, 95%CI: 1.100-1.544, = 0.002) and monthly income >10,000 (vs. <5,000, coefficient = 4.364, 95%CI: 1.738-10.956, = 0.002) were independently and positively associated with attitude. Only attitude (coefficient = 1.212, 95%CI: 1.096-1.340, < 0.001) was independently and positively associated with the practice. A structural equation modeling (SEM) analysis was used to estimate causality among KAP dimensions, showing that knowledge directly influenced attitude ( = -1.090, = 0.015), knowledge did not directly influence practice ( = -0.117, = 0.681) but had an indirect influence ( = 0.826, = 0.028), and attitude directly influenced practice ( = -0.757, = 0.016).
Women in Zhongshan City had good knowledge, favorable attitudes, and active practice toward breast ultrasound screening for breast cancer. Women's characteristics associated with a poorer KAP were identified, allowing for more targeted interventions.
有多种障碍可能会阻碍乳腺癌筛查。本研究旨在调查女性对乳腺癌超声筛查的知识、态度和实践（KAP）。
本横断面研究通过便利抽样招募了 2022 年 8 月至 2023 年 4 月期间在中山市人民医院乳腺专科门诊就诊的女性。将 KAP 得分≥70%视为充足。
本研究共纳入 501 名参与者。知识、态度和实践水平的平均值分别为 8.56±1.81/12（可能范围 0-12，71.33%）、29.80±2.71（可能范围 8-40，74.50%）和 32.04±3.09（可能范围 8-40，80.10%）。高中及以上教育（与初中及以下教育相比，系数=1.531，95%CI：1.013-2.312， =0.044）、本科及以上教育（与初中及以下教育相比，系数=5.315，95%CI：3.546-7.966， <0.001）、家庭主妇或失业（与就业相比，系数=0.671，95%CI：0.466-0.966， =0.032）和有过乳房超声检查史（与无检查史相比，系数=1.466，95%CI：1.121-1.917， =0.005）与知识呈独立正相关。知识（系数=1.303，95%CI：1.100-1.544， =0.002）和月收入>10,000 元（与<5,000 元相比，系数=4.364，95%CI：1.738-10.956， =0.002）与态度呈独立正相关。只有态度（系数=1.212，95%CI：1.096-1.340， <0.001）与实践呈独立正相关。结构方程模型（SEM）分析用于估计 KAP 各维度之间的因果关系，结果表明知识直接影响态度（ =-1.090， =0.015），知识不直接影响实践（ =-0.117， =0.681），但有间接影响（ =0.826， =0.028），态度直接影响实践（ =-0.757， =0.016）。
中山市女性对乳腺癌超声筛查的知识、态度和实践较好。确定了与较差 KAP 相关的女性特征，从而可以进行更有针对性的干预。
