目的通过分析贵州省老年梅毒流行特点,为改进梅毒防治策略提供科学依据。方法利用2005—2007年我省法定传染病网络直报系统的梅毒报告疫情资料,运用流行病学方法对疫情进行统计分析。结果2005—2007年,贵州省共报告≥60岁的老年梅毒626例,老年梅毒报告发病率由2005年的2.58/10万上升到2007年的8.58/10万(χ2=123.7029,P<0.01);其中男性病人448例,女性病人178例,男、女性别比为2.52∶1;71.24%的病人是离退休人员;各期梅毒均有不同程度的增长,老年隐性梅毒报告病例增长最快、所占比例最高(49.36%);隐性梅毒报告病例显著高于20～59岁年龄段的成人病例(χ2=50.2405,P<0.01);男、女老年各期梅毒所占比例不同,男性Ⅰ期梅毒报告病例显著多于女性报告病例(FisherTestP=0.0001354)。结论贵州省老年梅毒流行呈上升趋势,需采用适合老年人群的干预措施,以城镇离退休人员中男性人群作为干预的高危人群,减少梅毒在老年人群中的扩散。
Objective To analyze the epidemic characteristics of syphilis among old people in Guizhou Province and provide a scientific basis for the improvement of syphilis prevention and control strategies.

Results A total of 626 elderly syphilis aged 60 or older were reported in Guizhou Province during 2005-2007. The incidence of syphilis in elderly patients increased from 2.58 / 100,000 in 2005 to 8.58 / 100,000 in 2007 (χ2 = 123.7029, P <0.01) Among them, 448 were male patients and 178 were female patients. The male-female ratio was 2.52:1. 71.24% of the patients were retired. The syphilis in different stages had different degrees of growth, (49.36%). The reported cases of latent syphilis were significantly higher than those of adults aged 20-59 (χ2 = 50.2405, P <0.01). The proportion of syphilis among men and women was different The number of stage Ⅰ syphilis cases was significantly higher than that of female cases (Fisher Test P = 0.0001354). Conclusion The prevalence of syphilis among elderly people in Guizhou province is on the rise.
