【摘要】 目的 分析2017-2021年中山市跌倒/坠落病例的流行病学特征，为制定相关防控措施提供依据。方法 通过中山市伤害监测系统收集2017年1月-2021年12月跌倒/坠落病例资料，采用描述性流行病学方法分析病例的人口学分布、发生地点、活动状态、受伤部位及严重程度等病例特征。结果 2017-2021年中山市哨点医院报告跌倒/坠落病例56 787例，占伤害总数的30.60%,连续5年为伤害发生的首要原因。男女性别比例为1.58∶1。跌倒/坠落主要发生在0～14岁人群（44.29%）,不同年龄段间比较差异有统计学意义（χ²=1 782.872,P<0.001）。发生地点以家中（36.14%）为主，不同发生地点间比较差异有统计学意义（χ²=1 681.733,P<0.001）。常见于休闲活动（40.48%）,不同活动状态间比较差异有统计学意义（χ²=1 522.181,P<0.001）。主要导致锐器伤/开放伤（53.48%）,不同伤害性质间比较差异有统计学意义（χ²=262.312,P<0.001）。常见部位为头颈部（36.15%）和下肢（22.98%）,不同伤害部位间比较差异有统计学意义（χ²=126.970,P<0.001）。随着年龄增长重度伤构成比呈上升趋势(χ²_趋势=106.901,P<0.001),伤害结局的严重程度也随着年龄增长呈上升趋势(χ²_趋势=894.915,P<0.001)。结论 中山市伤害发生的首要原因是跌倒/坠落，男性多于女性，要重点关注0～14岁人群，加强头部及下肢的防护，减少家中致跌因素。更多还原

【Abstract】 Objective To explore the epidemiological characteristics of falls in Zhongshan city from 2017 to 2021,so as to provide scientific basis for falls prevention and control measures. Methods The fall cases from the Injury Surveillance System of Zhongshan city from January 2017 to December 2021 were collected, descriptive epidemiological methods were used to analyze case characteristics such as demographic distribution of cases, location of occurrence, activity status, site of injury and severity. Results A total of 56 787 cases of falls were reported in injury surveillance hospitals, accounting for 30.60% of all the injuries cases, and had occupied the first place in the cause of injury in 5 consecutive years.Falls occurred predominantly in the age group of 0-14 years（44.29%）,with a statistically significant difference in the comparison between different age groups（χ²=1 782.872,P<0.001）.The place of occurrence was predominantly at home（36.14%）,with a statistically significant difference in comparison between different places of occurrence（χ²=1 681.733,P<0.001）.It was commonly seen in leisure activities（40.48%） and the difference was statistically significant when comparing between different activity states（χ²=1 522.181,P<0.001）.It mainly resulted in sharp/open injuries（53.48%）,with a statistically significant difference in comparison between different nature of injuries（χ²=262.312,P<0.001）.The common sites were head and neck（36.15%） and lower limbs（22.98%） with statistically significant difference in comparison between different injury sites（χ²=126.970,P<0.001）.The composition ratio of severe injuries tended to increase with age(χ²_trend=106.901,P<0.001),and the severity of injury outcomes also tended to increase with age(χ²_trend=894.915,P<0.001). Conclusion The leading cause of injuries in Zhongshan city is falls/trips, with males outnumbering females.It is important to focus on the 0-14 year olds, strengthen head and lower extremity protection, and reduce fall-causing factors in the home.更多还原
