The International Classification of Diseases 10^th revision served as a tool for identifying and coding injury death (V01-Y98), including unintentional injury, intentional injury and other injuries. <b>Results:</b> From 2009 to 2022, a total of 4 452 injury deaths were recorded.

The top four causes of injury death were road traffic injuries (22.3/100 000 person-years), falls (18.0/100 000 person-years), suicide (9.1/100 000 person- years), and drowning (4.4/100 000 person-years).

The overall incidence showed stable fluctuation before 2020, and the annual incidence was high during February to May. The incidence was significantly higher in men (1.24/100 000) than in women (0.53/100 000) (<i>χ</i>²=207.86,<i>P</i><0.001). A higher incidence was observed in age group ≥60 years (2.37/100 000). Global spatial autocorrelation was identified in 2015, 2017, 2022, 2023, and 2024 (<i>P</i><0.001). High-high clustering areas were in Baodi, Hebei, Nankai, Hexi and Heping districts. Spatiotemporal scanning analysis identified five high-incidence clustering areas, with the first-level clustering area in Baodi, involving Jizhou, Wuqing, Beichen, Ninghe, and Hongqiao districts (<i>RR</i>=3.76, log-likelihood ratio=148.21, <i>P</i><0.001). <b>Conclusions:</b> From 2015 to 2024, the incidence of hepatitis E in Tianjin showed an overall increasing trend with significant spatiotemporal clustering. The prevention and control of hepatitis E should be strengthened in populations at high risk, especially in those aged ≥60 years, and targeted intervention should be conducted for high incidence clusters in both central urban area and outer suburban area.</p>","PeriodicalId":23968,"journal":{"name":"中华流行病学杂志","volume":"47 7","pages":"1311-1317"},"PeriodicalIF":0.0,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148593607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
