To investigate whether the willingness to exercise (WTE) and exercise habits affect the incidence of disability among older adults.
This study included 8,354 individuals (72.5 ± 6.2 years, 55.9% female). The participants were divided into three categories based on their WTE: unwillingness to exercise, willingness to exercise (but without exercise habits), and exercise habits. The incidence of disability was prospectively determined within 24 months of the follow-up. Cox regression analysis was used to examine the relationship between WTE and the incidence of disability.
Overall, 600 (7.2%), 4,703 (56.3%), and 3,051 (36.5%) participants were classified as unwillingness to exercise, willingness to exercise, and exercise habits, respectively. Compared with the unwillingness to exercise group, the willingness to exercise group (hazard ratio [HR] 0.71, 95%Confidence Interval [CI] 0.52-0.96) and the exercise habits group (HR 0.65, 95%CI 0.46-0.92) had a lower risk of disability incidence.
These results suggest that WTE reduces the risk of disability in older adults. Therefore, the importance of increasing WTE to prevent the occurrence of disabilities is clear. Our results suggest that even though physical activity declines with age, it is important to have the desire to exercise and develop exercise habits.
探讨运动意愿（WTE）和运动习惯是否会影响老年人的残疾发生率。
本研究纳入了8354名个体（年龄72.5±6.2岁，女性占55.9%）。参与者根据其运动意愿分为三类：不愿运动、有运动意愿（但无运动习惯）和有运动习惯。在随访的24个月内前瞻性地确定残疾发生率。采用Cox回归分析来检验运动意愿与残疾发生率之间的关系。
总体而言，分别有600名（7.2%）、4703名（56.3%）和3051名（36.5%）参与者被归类为不愿运动、有运动意愿和有运动习惯。与不愿运动组相比，有运动意愿组（风险比[HR]0.71，95%置信区间[CI]0.52 - 0.96）和有运动习惯组（HR 0.65，95%CI 0.46 - 0.92）的残疾发生率风险较低。
这些结果表明运动意愿可降低老年人的残疾风险。因此，提高运动意愿以预防残疾发生的重要性显而易见。我们的结果表明，尽管身体活动会随着年龄增长而减少，但有运动的欲望并养成运动习惯很重要。
