As cervical cancer becomes one of the most preventable cancers worldwide due to the extensive use of HPV vaccines and screening techniques, the cervical cancer death rate has decreased in high-income countries (HICs) in the past few decades while the burden is still increasing in low- and middle-income countries (LMICs), especially those in Africa, Asia, and Latin America. As a populous country, China has launched the "Healthy China 2030” strategy with the cervical cancer screening program as a key objective of the reform to accelerate the elimination of cervical Cancer. Shenzhen was selected as a pilot city for the reform of the cervical cancer screening program. However, because of the lagging integration of the information system, the current coverage of cervical cancer screening is hard to estimate.

Collaborating with the Shenzhen Maternity and Child Hospital, we aim to estimate the cervical cancer screening coverage among women aged 30 or older in Longhua District, Shenzhen, examine factors associated with cervical cancer screening participation, and explore facilitators and barriers to cervical cancer screening participation and follow-up among Chinese women. This study is a cross-sectional study with a mixed methodology. A quantitative approach will be used to estimate the cervical cancer screening coverage and examine its risk factors by questionnaire survey. A qualitative approach will be used to explore the underlying reasons of the existing facilitators and barriers to cervical cancer screening participation and following-up by in-depth interviews.
