Abstract:
Cervical cancer is one of the most common malignant tumors among women worldwide and represents a significant public health issue threatening women's health. In recent years, the disease burden of cervical cancer in China has been increasing, with women aged 45 and older bearing a particularly heavy burden. This population not only has the highest incidence and mortality rates but also represents the second peak age group for high-risk human papilloma virus (HR-HPV) infection, with the HR-HPV infection rate remaining consistently high. The causes of this situation are multifaceted. On one hand, the target group for HPV vaccination in China is women aged 9-45, which has resulted in very limited vaccination rates among middle-aged and older women when they were within the recommended age range. Additionally, this demographic has relatively low awareness of the HPV vaccine. On the other hand, aging-related declines in immune function and hormonal changes increase the risk of persistent HR-HPV infection in this group. The latent nature of HPV infection further complicates the early detection of the disease. At the same time, cervical cancer screening coverage among middle-aged and older women in China remains low and shows significant regional disparities, with screening rates in economically disadvantaged areas being markedly lower than those in more affluent regions. Furthermore, physiological changes associated with aging reduce the accuracy of conventional screening methods in this population, leading to insufficient early detection and intervention for cervical cancer. As a result, many patients are diagnosed at an advanced stage of the disease, significantly increasing treatment difficulty and disease burden. This article reviewed the burden of cervical cancer and HR-HPV infection among middle-aged and older women in China, the associated influencing factors, and the status of comprehensive prevention and control measures, aiming to provide a reference for improving cervical cancer prevention strategies for middle-aged and older women in China and contribute to the country's efforts to eliminate cervical cancer.
