Objective

To analyse the trend of the disease burden of common malignancies of the female reproductive system and the influence of age, period and birth cohort in China from 1990 to 2019.

Design

We used the joinpoint model based on the global burden of disease (GBD 2019) database to explore the trend of the burden of common malignancies of the female reproductive system in China from 1990 to 2019, and further analyzed the impact of age, period, and birth cohort using the age-period-cohort model.

Setting

GBD data from 1990 to 2019.

Participants

Data were publicly available and individuals were not involved.

Main outcomes

Outcomes included age standardised incidence rate, standardised mortality, standardised disability-adjusted life year (DALY), annual percentage change, average annual percentage change, age (period, cohort) effect coefficient, relative coefficient and SE. Akchi information criterion and Bayesian information criterion were used to estimate model goodness of fit.

Results

From 1990 to 2019, the standardised incidence and prevalence of cervical cancer and endometrial cancer increased, while the standardised mortality and DALY rate decreased. The standardised incidence, prevalence, mortality and DALY rates of ovarian cancer increased. The risk of cervical cancer, ovarian cancer and endometrial cancer increased first and then decreased with age, reaching its peak at ages 55, 70 and 55, respectively, while the risk of death increased with age. The risk of the onset and death of cervical cancer and ovarian cancer increased with the period, while those of endometrial cancer increased first and then decreased. The cohort with later female reproductive system malignancies had a lower risk of morbidity and mortality than the previous cohort.

Conclusion

From 1990 to 2019, the disease burden of malignant tumours in the female reproductive system in China was high. Relevant departments should pay attention to the prevention and treatment of malignant tumours in the reproductive system. Middle-aged and elderly women are the key target group for prevention and control.
