Abstract:
ObjectiveTo explore the epidemiological characteristics of poisoning cases in Qingpu District, Shanghai, and to provide a scientific basis for the prevention and control of poisoning within the district. MethodsA retrospective study was conducted to collect the information of 3 415 poisoning cases admitted to sentinel hospitals from 2018 to 2024. Descriptive statistical analyses were performed regarding the causes of poisoning, types of toxicants, gender and age distribution, and temporal distribution. Chi-square tests were used to analyze differences among groups. ResultsMales accounted for 64.30% of the poisoning cases, and the 20‒39 years old group (51.27%) constituted the largest proportion. The top three causes of poisoning were alcohol abuse (61.00%), suicide (15.20%), and accidental ingestion (9.93%). The distribution of poisoning causes varied significantly by gender and age groups (P<0.001). Among cases aged 10 years old and below, the main causes of poisoning were accidents/disasters and accidental ingestion; among cases aged 20 to 69 years old, alcohol abuse was the primary cause; among cases aged 11 to 19 years old and 70 years old and above, suicide was the primary cause of poisoning. The categories of toxic subtances included alcohol (61.41%), drugs (21.93%), pesticides or rodenticides (6.21%), toxic gases or liquids (5.68%), and venomous animals (3.95%). The composition of toxic subtance categories differed by gender (χ²=714.8, P<0.001): males were primarily poisoned by alcohol (78.32%), while females were primarily poisoned by drugs (45.53%). Poisoning occurred most frequently in January, July, and August. Alcohol poisoning peaked in January; pesticide or rodenticide poisoning peaked in June‒July; toxic gas or liquid poisoning (CO accounted for 69.59%) peaked in December and January; venomous animal poisoning (bee stings accounted for 97.78%) peaked from June to August. There were 8 deaths for the poisoning cases, with a case fatality rate of 0.23%. ConclusionThe situation of poisoning in this district was relatively severe. Prevention and control measures targeting the characteristics of poisoning in different populations and the distinct peak periods should be implemented to reduce the incidence of poisoning in the district.
