Analysis of the Epidemiological Characteristics and Influencing Factors of Fall Severity among Older Adults in Jiulongpo District,Chongqing
摘要
Abstract
Objective The aim of this study was to investigate the epidemiological characteristics and independent risk factors for fall-related injury severity among older adults in Jiulongpo District,Chongqing,providing evidence for developing targeted strate-gies to prevent severe fall injuries.Methods This study employed a cross-sectional survey design.Data were sourced from all injury cases reported through the"Chongqing Chronic Disease Surveillance System-Injury Surveillance"by 22 sentinel hospitals in Jiulongpo District,Chongqing,between July 2024 and July 2025.Cases aged≥60 years with falls as the injury cause were selected as study subjects.Demographic characteristics,injury circumstances,and underlying medical conditions were collected.Injury severity(classified as mild or moderate/severe)served as the dependent variable.Univariate analysis employed the chi-square test,while uni-variate analysis and multivariate unconditional logistic regression models identified independent factors associated with moderate/severe injuries following falls among the elderly.The significance level was set at α=0.05.Results A total of 3,709 elderly fall cases were included.Females predominated,accounting for 68.46%.The primary age groups were 60～69 years(1,502 cases,40.50%)and 70～79 years(1,336 cases,36.02%).The main location of falls was at home(2,675 cases,72.12%).Mild injuries occurred in 1,842 cases(49.66%),while moderate/severe injuries occurred in 1,867 cases(50.34%).The nature of injury was closely correlated with injury severity,with fractures accounting for 91.64%(1,711/1,867)of moderate/severe injuries.Multivariate logistic regression analy-sis revealed that female gender(OR=1.376,95%CI:1.194～1.585),age 70～79 years(OR=1.415,95%CI:1.159～1.727)and≥80 years(OR=1.221,95%CI:1.045～1.425),diabetes(OR=2.181,95%CI:1.680～2.831),central obesity(OR=1.342,95%CI:1.040～1.731)had higher detection rates of moderate/severe injuries.Individuals with primary school education(OR=0.749,95%CI:0.597～0.940)and junior high school education or higher(OR=0.784,95%CI:0.633～0.971)had lower detection rates of moderate/severe injuries.Conclusion The incidence of moderate/severe injuries following falls among older adults in Jiulongpo District,Chongqing is high.Key risk factors include female gender,advanced age(≥70 years),diabetes,and central obe-sity.Fall prevention strategies should target high-risk populations through comprehensive measures such as health education,chronic disease and weight management,and home modifications for aging-friendly environments to effectively reduce the risk of severe injury.关键词
