With the global population growing older, there is a need for more knowledge of how to improve and/or maintain functional capacities to promote healthy ageing. In this study we aimed to assess the effect of several known health-promoting behaviors in old age with intrinsic capacity ten years later.
This was a prospective cohort study looking at participants that were ≥ 65 years at the time of the third wave of the Trøndelag Health Study (HUNT3, 2006-2008) who also took part in the 70 + sub-study of the fourth wave (HUNT4 70+, 2017-2019). Self-reported behavior data from short questionnaires, including diet and physical activity, were collected in HUNT3, and data on the five domains of intrinsic capacity defined by the World Health Organization were collected in HUNT4 70+. A composite index was created for both healthy life and intrinsic capacity, awarding points for how well participants adhered to guidelines for healthy living and their level of functional impairment, respectively. Ordinal logistic regression was used to assess the relationship between health-promoting behaviors and intrinsic capacity.
Of 12,361 participants in HUNT3 ≥ 65 years, 4699 (56.5% women) also participated in HUNT4 70+. On the health-promoting behaviors, lowest adherence to healthy living guidelines were seen for fruit and vegetables intake (47.2%), milk intake (46.7%) and physical activity (31.1%). On intrinsic capacity domains, highest impairment was seen in the domains of locomotion (29.7%), hearing (11.1%) and vitality (8.3%). A higher adherence to guidelines for healthy living was associated with higher intrinsic capacity 10 years later. A one-point increase in the healthy life index was associated with a 1.15 (95% confidence interval 1.10-1.21) times increased odds of being in a higher intrinsic capacity category.
Health-promoting behaviors in old age are associated with better intrinsic capacity ten years later. In clinical settings assessment of health-promoting behaviors could potentially be done using short questionnaires.
随着全球人口老龄化，需要更多关于如何提高和/或维持功能能力以促进健康老龄化的知识。在这项研究中，我们旨在评估老年时的几种已知健康促进行为对 10 年后内在能力的影响。
这是一项前瞻性队列研究，观察第三波特隆德拉格健康研究（HUNT3，2006-2008 年）时年龄≥65 岁且参加第四次波的 70+子研究（HUNT4 70+，2017-2019 年）的参与者。HUNT3 中通过简短问卷收集了自我报告的行为数据，包括饮食和体育活动，而 HUNT4 70+中收集了世界卫生组织定义的内在能力的五个领域的数据。为健康生活和内在能力创建了一个综合指数，分别为参与者遵守健康生活指南的程度和功能障碍程度打分。使用有序逻辑回归评估健康促进行为与内在能力之间的关系。
在 HUNT3 中，有 12361 名年龄≥65 岁的参与者，其中 4699 名（56.5%为女性）也参加了 HUNT4 70+。在健康促进行为方面，最不遵守健康生活指南的是水果和蔬菜摄入（47.2%）、牛奶摄入（46.7%）和体育活动（31.1%）。在内在能力领域，运动能力（29.7%）、听力（11.1%）和活力（8.3%）受损最高。更遵守健康生活指南与更高的内在能力 10 年后相关。健康生活指数增加一个点与更高内在能力类别的几率增加 1.15 倍（95%置信区间 1.10-1.21）相关。
老年时的健康促进行为与 10 年后的内在能力更好相关。在临床环境中，健康促进行为的评估可以使用简短的问卷进行。
