Abstract:
Objective:To investigate the prevalence of Kashin-Beck disease (KBD) in Liaoning Province, analyze its disease progression, and provide a scientific basis for timely adjustment in prevention and control strategies and work priorities.Methods:From March 2019 to October 2024, a cross-sectional study was conducted in five KBD endemic townships in Liaoning Province. The monitoring was conducted on a village by village basis, including the name of the administrative village, the name of the natural village (township), the number of permanent households (residing for ≥6 months), the number of permanent residents, the number of permanent residents aged 7 to 12, the management and treatment of adult patients, the implementation of prevention and control measures, and the implementation of child nutrition improvement programs (grain replacement). Anteroposterior X-rays of both hands were taken for children with abnormal signs or suspected KBD. Cases were confirmed as KBD if both clinical examination and X-ray review were positive. Five-year KBD surveillance data were analyzed, including the numbers of clinically positive and X-ray positive cases at each monitoring site, with positive detection rates calculated to macroscopically analyze the dynamic changes in KBD status.Results:From 2019 to 2024, a total of 180 103 children aged 7 - 12 years old were monitored in KBD endemic villages in Liaoning Province. Among them, 321 children showed abnormal clinical signs, but hand X-rays revealed no positive changes indicative of KBD. The annual positive detection rate for KBD was 0 throughout the study period. In 2024, in 1 500 endemic natural villages (hamlets) in Liaoning Province, 39 205 acres of farmland were converted to economic crops (1.96% of original farmland), and 16 520 acres were returned to forest or grassland (1.74% of original farmland). There were 534 KBD patients, with a prevalence rate of 6.7/10 000. All patients had completed patient information management, follow-up evaluation, achieving a 100% management rate. Four hundred thirty-five patients with Kashin Beck disease were planned for treatment, but, 476 patients were actually treated with medication, resulting in a planned treatment completion rate of 109.43% and a patient treatment rate of 89.14%.Conclusion:From 2019 to 2024, Liaoning Province has achieved the goal of eliminating KBD and maintained sustained elimination status.
