Objective: To investigate the current status and influencing factors of moderate and severe injuries caused by falls among the elderly in Longhua District, Shenzhen City, Guangdong Province, so as to provide a basis for formulating prevention and control policies and intervention measures. Methods: Data on elderly patients (aged ≥60 years) who sought first-time outpatient or emergency treatment for falls at sentinel hospitals in Longhua District from January 1, 2021, to December 31, 2024, were collected through the Shenzhen Injury Surveillance System. The data included general information, basic characteristics of the fall incidents, and clinical characteristics of the fall-related injuries. Factors affecting moderate and severe injuries caused by falls among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 2 797 elderly fall cases were reported in Longhua District from 2021 to 2024, including 990 males (35.40%) and 1 807 females (64.60%). The mean age was (70.56±8.85) years. There were 1 305 cases of moderate and severe injuries, accounting for 46.66%. Multivariable logistic regression analysis showed that female (OR=1.428, 95%CI: 1.211-1.684); 70-<80 years (OR=1.391, 95%CI:1.153-1.679), or ≥80 years (OR=1.586, 95%CI: 1.260-1.996); falls occurring at home (OR=1.659, 95%CI: 1.142-2.409), or in public residential settings (OR=1.666, 95%CI: 1.029-2.697); and activities during the fall such as walking (OR=1.738, 95%CI: 1.383-2.183) or performing life activities (OR=1.562, 95%CI: 1.254-1.947) were associated with a higher risk of moderate and severe injuries among elderly fall cases. High school/secondary technical school education level (OR=0.695, 95%CI: 0.526-0.919) and occupation as professional and technical/clerical staff (OR=0.540, 95%CI: 0.310-0.942) were associated with a lower risk of moderate and severe injuries among elderly fall cases. Conclusions The proportion of moderate and severe injuries caused by falls among the elderly in Longhua District is relatively high, which is mainly associated with gender, age, education level, occupation, fall location and activity during the fall.

Objective: To understand the characteristics of injury cases in Longhua District, Shenzhen City, Guangdong Province from 2021 to 2024, so as to provide the evidence for the development of injury prevention and control measures. Methods: The data of injury cases in the first visit due to injury in the sentinel hospitals of Longhua District from 2021 to 2024 were collected from the Shenzhen Injury Surveillance System. The time, cause, place, activity, intention, nature, position, severity, and outcome of injury were described. Results: From 2021 to 2024, a total of 167 524 injury cases were reported in Longhua District, with a male-to-female ratio of 1.89∶1. The incidence of injuries was higher in cases aged 30-<45 years (49 957 cases, 29.82%). Injuries mainly occurred from July to August (31 272 cases, 18.67%). The main cause of injury was falls (52 048 cases, 31.07%). Injuries mainly occurred at home (64 110 cases, 38.27%). Leisure activities were the main activities when injuries occurred (79 008 cases, 47.16%). Most of the injuries were unintentional (159 173 cases, 95.02%). The main type of injury was contusion/abrasion (71 900 cases, 42.92%). The main injury site was upper limb (64 247 cases, 38.35%). Most injuries were mild (131 369 cases, 78.42%). The main injury outcome was discharge after treatment, 160 882 cases (96.04%). The second cause of male injury was blunt force injury (30 140 cases, 27.49%), and the second cause of female injury was animal injury (14 648 cases, 25.31%). Fall was the leading cause of injury in people aged 0-<15 years and ≥65 years, and blunt force injury was the leading cause of injury in people aged 15-<65 years. The second place for male injuries was industrial and construction places (23 722 cases, 21.64%), and for female injuries was school/public places (9 644 cases, 16.66%). The first place for injuries in people aged 45-<65 years was in industrial and construction places. The proportions of fractures, moderate injuries, and hospitalizations increased with age (all P<0.05). Conclusions The main injury cases in Longhua District were males and people aged 30-<45 years. July and August were a period of high risk for injuries. People aged 0-<15 years and ≥65 years were the high-risk groups of falls. More attention should be paid to the fracture risk in the elderly.
