The incidence of fall-related hip fractures in old patients aged over 85 years was reported to be higher than that in old patients aged between 65 and 84 years; however, there are no known studies that reported differences of these age groups with respect to the falling situation.
This study investigated the association between age and falling direction in patients with hip fractures.
This study analyzed the medical records of older patients with fall-related hip fractures who were hospitalized in 2011-2018. Demographic (sex, age, and body mass index, BMI), medical and clinical (body mineral density, type of fracture, and cognitive function), and lifestyle variables (use of assistive device for locomotion and place of residence) and characteristics of falling (direction and location) were extracted. These were compared between the patients aged between 65 and 84 years (65-84 group) and over 85 years (85+ group). Multivariable logistic regression analysis was conducted to investigate associations with each falling direction (forward, sideways, and backward) with other variables.
Compared with the 65-84 group, the proportion of hip fractures due to sideways falls was lower in the 85+ group (P < 0.05) while the proportion of hip fractures due to backward falls was higher in the 85+ group. The multivariable logistic regression analysis showed the sideways and backward falling were only associated with the age group.
These results suggested that the falling direction was associated with age but not with other variables investigated in this study in older patients with hip fractures.
85 岁以上老年患者跌倒相关性髋部骨折的发生率高于 65-84 岁老年患者；然而，目前尚无研究报道这两个年龄组在跌倒情况方面存在差异。
本研究旨在探讨髋部骨折患者年龄与跌倒方向之间的关系。
本研究分析了 2011-2018 年因跌倒相关性髋部骨折住院的老年患者的病历。提取了人口统计学（性别、年龄和体重指数，BMI）、医疗和临床（身体矿物质密度、骨折类型和认知功能）以及生活方式变量（助行器的使用和居住地点）和跌倒特征（方向和地点）。将这些变量在年龄在 65-84 岁之间的患者（65-84 岁组）和 85 岁以上的患者（85+ 组）之间进行比较。多变量逻辑回归分析用于调查与每个跌倒方向（向前、侧向和向后）相关的其他变量。
与 65-84 岁组相比，85+ 岁组因侧向跌倒导致髋部骨折的比例较低（P<0.05），而因向后跌倒导致髋部骨折的比例较高。多变量逻辑回归分析显示，侧向和向后跌倒仅与年龄组有关。
这些结果表明，跌倒方向与年龄有关，但与本研究中髋部骨折老年患者调查的其他变量无关。
