This study aimed to assess the knowledge, attitudes and practices (KAP) towards cervical cancer screening among ethnic minorities in Inner Mongolia, China. A cross-sectional study was conducted in Inner Mongolia between May and September, 2023, and recruiting participants undergoing dual-cancer screening. Demographic characteristics and KAP status were assessed using a self-administered questionnaire. A total of 533 valid questionnaires were collected, with 53.66% aged 40 years or younger. Mean scores for knowledge, attitude, and practice were 13.58 ± 5.41, 41.06 ± 4.53, and 13.35 ± 1.53, respectively. Positive associations were found between knowledge and attitude (r = 0.348, p < 0.001), knowledge and practice (r = 0.288, p < 0.001), and attitude and practice (r = 0.817, p < 0.001). Structural equation modelling confirmed direct positive associations between knowledge and attitude (path coefficient = 0.307, p < 0.001) and attitude and practice (path coefficient = 0.270, p < 0.001). Additionally, knowledge demonstrated an indirectly positive association with practice (path coefficient = 0.083, p = 0.007). Ethnic minorities in Inner Mongolia exhibit insufficient knowledge, positive attitudes, and proactive practices toward cervical cancer screening. Implementing targeted educational initiatives is crucial to enhance their KAP.
