A previous study suggested older drivers with subjective memory concerns (SMC) had increased odds of experiencing car collisions, but whether SMC in different contexts and the number of SMC applicable items change this association is unknown. The aim of this study was to examine the association between SMC and car collisions among older drivers in Japan.
This cross-sectional study was conducted using data from a Japanese community-based cohort study. Participants were community-dwelling older adults aged ≥60 years. SMC was assessed using five questions: 1) "Do you feel you have more problems with memory than most?" 2) "Do you have any difficulty with your memory?" 3) "Do you forget where you have left things more than you used to?" 4) "Do you forget the names of close friends or relatives?" and 5) "Do other people find you forgetful?" Participants were asked about their experiences with car collisions during the previous two years.
A total of 13,137 older drivers (72.1 ± 5.5 years old, and 43.6 % female) were analyzed. Cochran-Armitage trend test showed that as the number of SMC applicable items increased, the percentage of the experiences of car collisions significantly increased (6.8 %-15.8 %, P < 0.001). Logistic regression models showed each SMC question was associated with an increased odds ratio (OR) of car collisions (OR 1.26 to 1.71, all P < 0.001) after adjusting for confounding factors. As the number of SMC applicable items increased, the OR of car collisions significantly increased (OR 1.19 to 2.28, all P < 0.05, P for trend <0.001).
This cross-sectional study among community-dwelling older drivers in Japan suggested each SMC question and the number of applicable items were associated with car collisions. SMC may be a sign of increased risk of traffic incidents for older drivers.
先前的一项研究表明，有主观记忆问题（SMC）的老年驾驶员发生汽车碰撞的几率增加，但在不同背景下的SMC以及适用的SMC项目数量是否会改变这种关联尚不清楚。本研究的目的是调查日本老年驾驶员中SMC与汽车碰撞之间的关联。
本横断面研究使用了一项基于日本社区的队列研究的数据。参与者为年龄≥60岁的社区居住老年人。使用五个问题评估SMC：1）“你是否觉得自己的记忆力问题比大多数人多？”2）“你的记忆力有困难吗？”3）“你是否比过去更容易忘记东西放在哪里？”4）“你是否会忘记亲密朋友或亲戚的名字？”以及5）“其他人是否觉得你健忘？”询问参与者在前两年内的汽车碰撞经历。
共分析了13137名老年驾驶员（年龄72.1±5.5岁，女性占43.6%）。 Cochr an-Armitage趋势检验表明，随着适用的SMC项目数量增加，汽车碰撞经历的百分比显著增加（6.8%-15.8%，P<0.001）。逻辑回归模型显示，在调整混杂因素后，每个SMC问题都与汽车碰撞的优势比（OR）增加相关（OR为1.26至1.71，所有P<0.001）。随着适用的SMC项目数量增加，汽车碰撞的OR显著增加（OR为1.19至2.28，所有P<0.05，趋势P<0.001）。
这项针对日本社区居住老年驾驶员的横断面研究表明，每个SMC问题和适用项目数量都与汽车碰撞相关。SMC可能是老年驾驶员交通事故风险增加的一个迹象。
