Abstract

Background: Chlamydia is common among women of reproductive age and can cause serious health issues. This study aimed to examine the trends and factors linked to newly diagnosed and reported chlamydia cases in women aged 15-49 in Guangdong Province from 2006 to 2020.

Methods: We included all newly diagnosed and reported chlamydia cases from January 1, 2006, to December 31, 2020. Data from 21 cities in Guangdong Province were sourced from the National Notifiable Infectious Disease Reporting Information System in China. Temporal trends were analyzed using Joinpoint regression models. City-level factors (population density, net migration rate, and male-to-female sex ratio) were derived from the Guangdong Statistical Yearbook and the Guangdong Health and Family Planning Statistical Yearbook. Quasi-Poisson regression models were used to explore the relationship between sociodemographic factors and chlamydia incidence.

Results: From 2006 to 2020, 523,367 new chlamydia cases were reported among women of reproductive age in Guangdong. The mean reported rate was 122.6 per 100,000 population over 15 years, significantly increasing from 1.4 in 2006 to 179.7 in 2020 (average annual percent change [AAPC] = 47.4%, 95% CI: 42.8%-52.2%, P < 0.05). The highest rate was 196.8 per 100,000 population in 2019. Among older women, 9,045 cases were reported, with a mean reported rate of 4.9 per 100,000, rising significantly from 0.01 in 2006 to 9.6 in 2020 (AAPC = 52.6%, 95% CI: 30.3%-78.8%, P < 0.05). The reported rate among women of reproductive age correlated with the net migration rate (RR = 1.2; 95% CI: 1.2-1.3) and the ratio of those participating in child-bearing insurance to the permanent population (RR = 1.5; 95% CI: 1.4-1.6).

Conclusion: The reported rate of new chlamydia cases among women of reproductive age was significantly higher than among older adults and increased markedly from 2006 to 2020. These findings underscore the urgent need for targeted prevention strategies for women of reproductive age.

2006-2020年中国南方育龄妇女衣原体病例监测数据分析
背景:衣原体在育龄妇女中很常见,可引起严重的健康问题。本研究旨在探讨2006 - 2020年广东省15-49岁女性衣原体新诊断和报告病例的趋势和相关因素。方法:纳入2006年1月1日至2020年12月31日所有新诊断和报告的衣原体病例。来自广东省21个城市的数据来自中国国家法定传染病报告信息系统。使用Joinpoint回归模型分析时间趋势。城市层面的因素(人口密度、净迁移率和男女性别比)来自广东省统计年鉴和广东省卫生和计划生育统计年鉴。采用准泊松回归模型探讨社会人口学因素与衣原体发病率的关系。结果:2006 - 2020年,广东省育龄妇女衣原体新发病例523367例。15年平均报告检出率为122.6 / 10万,从2006年的1.4 / 10万显著增加到2020年的179.7 / 10万(年均变化率[AAPC] = 47.4%, 95% CI: 42.8% ~ 52.2%, P结论:2006 - 2020年育龄妇女衣原体新发病例报告率显著高于老年人,且显著增加。这些发现强调了迫切需要为育龄妇女制定有针对性的预防战略。
