To examine the relationship of driving status and frailty with disability in older adults.
A prospective study.
The study included 8533 participants (mean age: 72.0±6.1 years (range: 60-98 years), women: 54.1%) in a community setting.
Driving status and frailty were assessed at baseline. The clinical definition of frailty was used according to the Japanese Cardiovascular Health Study index. Disability was prospectively determined using a record of Japanese long-term care insurance (LTCI).
During the follow-up period (mean duration: 23.5 months), 58 (0.7%) participants were regarded as moving out of the city, 80 (0.9%) participants had died and 311 (3.6%) participants were certified by LTCI. The proportion of disability was 1.3% among the not-frail group and 5.3% among the frail group. The proportion of disability was 2.5% in participants who were currently driving and 7.5% in those not driving. Based on frailty status and driving, participants were further classified into four groups: not frail and currently driving (n=2945), not frail and not driving (n=642), frail and currently driving (n=3598) and frail and not driving (n=1348). Compared with older adults who are not frail and driving, the combined status of frail and not driving (adjusted HR: 2.28; 95% CI: 1.47 to 3.52) and frail and driving (HR: 1.91; 95% CI: 1.30-2.81) were risk factors for disability.
Not driving and frail were associated with a risk of disability in community-dwelling older adults.
研究老年人的驾驶状态和身体虚弱与残疾之间的关系。
一项前瞻性研究。
该研究纳入了8533名社区参与者（平均年龄：72.0±6.1岁（范围：60 - 98岁），女性占54.1%）。
在基线时评估驾驶状态和身体虚弱情况。身体虚弱的临床定义采用日本心血管健康研究指数。残疾情况通过日本长期护理保险（LTCI）记录进行前瞻性判定。
在随访期间（平均时长：23.5个月），58名（0.7%）参与者被视为搬离城市，80名（0.9%）参与者死亡，311名（3.6%）参与者通过LTCI认证。非虚弱组的残疾比例为1.3%，虚弱组为5.3%。当前仍在驾驶的参与者残疾比例为2.5%，未驾驶的参与者为7.5%。根据身体虚弱状态和驾驶情况，参与者进一步分为四组：非虚弱且当前仍在驾驶（n = 2945）、非虚弱且未驾驶（n = 642）、虚弱且当前仍在驾驶（n = 3598）以及虚弱且未驾驶（n = 1348）。与非虚弱且驾驶的老年人相比，虚弱且未驾驶（调整后HR：2.28；95%CI：1.47至3.52）以及虚弱且驾驶（HR：1.91；95%CI：1.30 - 2.81）的综合状态是残疾的危险因素。
在社区居住的老年人中，未驾驶和身体虚弱与残疾风险相关。
