摘要:
目的 分析2005—2023年云南省学校学生梅毒流行趋势与变化特征,为学校梅毒综合防控工作提供依据。 方法 从中国疾病预防控制信息系统中获得2005—2023年云南省学生梅毒病例资料,采用Joinpoint回归模型对梅毒报告发病率进行时间趋势分析。 结果 2005—2023年云南省累计报告学生梅毒病例3 191例(男生1 248例,女生1 943例),报告发病率由2005年的0.17/10万上升至2023年的8.26/10万,AAPC为24.89%(Z=13.18, P < 0.01)。女生报告发病率高于男生(χ2=229.48);小学、初中、高中、高等教育阶段发病率分别为0.21/10万、2.42/10万、4.45/10万、6.29/10万,差异有统计学意义(χ2=3 432.84),初中阶段发病率平均每年增长幅度最大(AAPC=30.68%,Z=7.57),高中阶段次之(AAPC=24.28%,Z=5.70);一、二期梅毒报告发病率由2005年的0.12/10万上升到2023年的2.06/10万,AAPC为16.86%(Z=4.57)(P值均 < 0.05)。 结论 云南省学生梅毒报告发病率总体呈持续上升趋势,初中阶段报告发病率平均每年增长幅度最大。学校需重视梅毒宣教,扩大宣教覆盖面,遏制校园梅毒的发生与传播。 Abstract:Objective To analyze epidemiological trends and changing characteristics of syphilis among students in Yunnan Province from 2005 to 2023, so as to provide evidence for the comprehensive prevention and control of syphilis in schools. Methods The case data of syphilis among students in Yunnan Province from 2005 to 2023 were obtained from the China Information System for Disease Control and Prevention. The Joinpoint regression model was used to conduct a time trend analysis of the reported incidence rate of syphilis. Results From 2005 to 2023, a cumulative total of 3 191 cases of syphilis were reported in schools in Yunnan Province(1 248 male cases and 1 943 female cases). The reported incidence rate rose continuously from 0.17/100 000 in 2005 to 8.26/100 000 in 2023, with an average annual percent change (AAPC) of 24.89%(Z=13.18, P < 0.01). The reported incidence rate was higher in female students than in male students (χ2=229.48, P < 0.05). The incidence rates in the primary school, junior high school, senior high school and higher education were 0.21/100 000, 2.42/100 000, 4.45/100 000 and 6.29/100 000 respectively, and the difference was statistically significant(χ2=3 432.84, P < 0.05). The average annual growth rate was the highest in the junior high school stage(AAPC=30.68%, Z=7.57, P < 0.05), followed by the senior high school stage (AAPC=24.28%, Z=5.70, P < 0.05).The reported incidence rate of primary and secondary syphilis increased from 0.12/100 000 in 2005 to 2.06/100 000 in 2023, with an AAPC of 16.86% (Z=4.57, P < 0.05). Conclusions The overall reported incidence rate of syphilis among students in schools in Yunnan Province shows a sustained upward trend, with the most rapid annual increase observed in junior high schools. Schools should prioritize syphilis education and expand awareness campaigns to curb transmission. -
