ABSTRACT
OBJECTIVE: To examine temporal trends in routine leucorrhea test results and associated pathogen findings among women participating in sustained cervical and breast cancer screening programs in a county-level city of western China.
METHODS: In this repeated cross-sectional screening study, routine leucorrhea test data were collected from women aged 35-64 years who participated in cervical and breast cancer screenings in Jianyang City, Sichuan Province, between January 2022 and December 2024 (12,156 cases in 2022, 13,824 cases in 2023, and 11,382 cases in 2024). Participants were stratified by age and region. Vaginal cleanliness and pathogens were assessed using the normal saline wet mount method. Statistical analyses were performed using SPSS 26.0, including trend analysis, linear regression, and stratified analyses to examine age-region interaction effects.
RESULTS: Over the three-year period, the abnormal rate of routine leucorrhea tests (Grade III-IV) decreased from 34.21% to 30.00%, corresponding to an annual reduction of 6.5% (P < 0.001). Infection rates of Candida albicans, Trichomonas vaginalis, and clue cell positivity declined concurrently. The 51-55 age group had the highest baseline abnormal rate but showed the most pronounced decrease (5.40% points). Stratified analysis indicated that township perimenopausal women (51-55 years) experienced the steepest improvement (7.2% points) compared with urban counterparts (3.8% points, P < 0.01). The urban-rural gap narrowed by 3.90% points (P < 0.001). Following the 2023 township healthcare initiative, township abnormal rates declined more steeply than the pre-intervention trend would have predicted (difference of 3.10% points); given the cross-sectional design, this difference should be interpreted as a temporal association rather than causal attribution.
CONCLUSION: Participation in a sustained, population-based screening program was temporally associated with a declining trend in abnormal leucorrhea findings among women aged 35-64 years in this county-level city of western China. Based on a preliminary linear trend estimate derived from three annual data points, the abnormal rate may decrease to approximately 26% by 2026 if current intervention intensity is maintained; this projection should be interpreted with caution given the limited time series. Because this is a repeated cross-sectional analysis, causal inference is not warranted. Targeted interventions for perimenopausal women and residents of township areas should be reinforced to optimize gynecological health services in western China.
