Development of Screening for Common Gynecological Diseases in Chinese Women (2007- 2020)

Abstract Background: The study aimed to analyze trends in the implementation of common gynecological disease screening in China under the influence of policies. Methods: An interrupted time series analysis with segmented linear regression was performed using gynecological disease screening data from 2007 to 2020 obtained from the official government statistical website. Statistical analysis focused on two important time points: the relaxation of the family planning policy and the major institutional reforms in the health sector in 2014 and the elevation of the "Healthy China Strategy" as a fundamental national policy in 2017. Results: Our results indicate an overall increasing trend in the screening rate, increasing from 38% to 86.58%. Prior to the relaxation of the family planning policy and the health sector reforms, the screening rate increased annually by 4.64% (P < 0.0001, CI= [3.06, 6.21]). However, in the first year of policy implementation, there was a 21% decrease (P ＜ 0.0001, CI= [-27.8, -14.2]). The COVID-19 pandemic in early 2020 also partially hindered screening progress, resulting in a decline in the annual growth rate from 10.16% to 4.13%. Conclusion: Women's health issues are receiving increasing attention, and the rising screening rates for gynecological diseases are due to the joint efforts of various stakeholders, including the government, society, and individuals. However, policy changes and environmental factors can impact the organized implementation of gynecological disease screening. Therefore, it is necessary to establish robust implementation plans and efficient process management to effectively address potential risks.
