Aging decreases physical function which can increase dependence in activities of daily living (ADL) and disability. However, physical activity (PA) may improve physical function and prevent disability in older adults. In addition, it is important to emphasize that research concerning the domains in which PA is practiced and the benefits for physical function of older adults is also important for the elaboration of preventative health measures for this population. Thus, the aim of this study was to analyse the association of total PA and PA in different domains and odds of disability in older adults in a 24-month follow-up. The study included 211 older adults, aged ≥60 years (72 ± 7 years, 72% women). Handgrip strength was measured using a digital dynamometer, gait speed and chair stand by functional tests. PA and dependence in ADL were self-reported. Older adults who remained sufficiently active in the occupational (OR:0.11;CI95%:0.01-0.93, OR:0.21;CI95%:0.07-0.69, and OR:0.13;CI95%:0.05-0.34) domain presented protection for high dependence in basic (BADL), instrumental (IADL) and advanced (AADL), respectively, as well as in total ADL (OR:0.25;CI95%:0.07-0.92). Older adults who remained sufficiently active in the leisure-time exercise (OR:0.28;CI95%:0.11-0.72, OR:0.44;CI95%:0.20-0.93 and OR:0.15;CI95%:0.04-0.49) domain presented protection for high dependence in IADL, AADL and total ADL, respectively. Moreover, older adults who remained sufficiently active in total PA (OR:0.11;CI95%:0.01-0.94, OR:0.30;CI95%:0.11-0.80 and OR:0.21CI95%:0.10-0.46) presented protection for high dependence in BADL, IADL and AADL, respectively, as well as in total ADL (OR:0.28;CI95%:0.09-0.86). The odds of disability are lower in older adults who are sufficiently active, especially in occupational and leisure-time exercise domains.
衰老是身体机能下降的主要原因，这会导致老年人日常生活活动能力（ADL）下降和残疾。然而，身体活动（PA）可以改善老年人的身体机能，预防残疾。此外，强调 PA 实践的领域以及对老年人身体功能的益处的研究对于制定这一人群的预防保健措施也很重要。因此，本研究旨在分析在 24 个月的随访中，总 PA 以及不同领域的 PA 与老年人残疾几率之间的相关性。该研究纳入了 211 名年龄≥60 岁的老年人（72±7 岁，72%为女性）。使用数字测力计测量握力，通过功能测试测量步态速度和椅站起。PA 和 ADL 依赖情况由自我报告得出。在职业（OR：0.11；95%CI：0.01-0.93，OR：0.21；95%CI：0.07-0.69，OR：0.13；95%CI：0.05-0.34）领域保持足够活跃的老年人，在基本日常生活活动能力（BADL）、工具性日常生活活动能力（IADL）和高级日常生活活动能力（AADL）以及总 ADL 方面都表现出了对高依赖的保护（OR：0.25；95%CI：0.07-0.92）。在闲暇时间锻炼（OR：0.28；95%CI：0.11-0.72，OR：0.44；95%CI：0.20-0.93，OR：0.15；95%CI：0.04-0.49）领域保持足够活跃的老年人，在 IADL、AADL 和总 ADL 方面都表现出了对高依赖的保护。此外，在总 PA（OR：0.11；95%CI：0.01-0.94，OR：0.30；95%CI：0.11-0.80，OR：0.21；95%CI：0.10-0.46）领域保持足够活跃的老年人，在 BADL、IADL 和 AADL 以及总 ADL 方面都表现出了对高依赖的保护（OR：0.28；95%CI：0.09-0.86）。在足够活跃的老年人中，残疾的几率较低，尤其是在职业和闲暇时间锻炼领域。
