BackgroundFalls in older people are a major public health problem due to associated morbidity and mortality. Their origin is most often multifactorial.Objective, Design And SubjectsThe objective of the present study, called ChuPaDom, was to identify patterns or profiles of home fallers (HF) - understood here as people who fall in their place of residence - among a sample of persons aged 65 and over who were hospitalized after a fall, and to study their association with falling-induced injuries using data from the ChuPAdom study.MethodsMultiple correspondence analysis and Hierarchical Clustering on Principal Components were performed. Multivariate logistic regression was used to test for associations between HF profiles and injuries.ResultsThe sample comprised 1467 patients (69% female, average age = 84.5 years). Five profiles were identified: youngest seniors who took risks and fell from a raised height, youngest seniors with specific health problems who fell down a stairs, autonomous seniors who fell because they lost their balance or fell from their own height, dependent seniors who fell during low-intensity activities, very old seniors for whom missing data were frequent. Fractures were more frequent among the first profile than the last two profiles constituted with more dependent individuals (p < 0.001).ConclusionThese results highlight the heterogeneity of the circumstances in which older people fall. A greater understanding of these circumstances is needed to implement targeted prevention actions.Copyright © 2022. Published by Elsevier Ltd.
