The aim of this article is to study the associations between healthy lifestyle in old age and decline in physical, psychological, cognitive, and social functioning. A population-based sample of 3,107 Dutch men and women aged 55 and 85 years (1992/1993; Longitudinal Aging Study Amsterdam) was used with five 3-yeary follow-up examinations. Lifestyle score, based on smoking status, alcohol consumption, physical activity, and body mass index (BMI), ranged from 0 () to 4 (). Outcomes included gait speed, depressive symptoms, cognitive status, and social contacts. Persons with a healthy lifestyle had a 10.6% slower decline in gait speed (0.04 m/s, 95% confidence interval [CI] = [0.03, 0.05]), 10.8% slower increase in depressive symptoms (-1.07 [-1.70, -0.44]), a 1.8% slower decline in cognitive functioning (0.47 [0.23, 0.70]), and a 4.9% slower decline in social contacts (0.58 [0.01, 1.15]) compared with persons with no or one healthy lifestyle factor. A healthy lifestyle benefits physical, psychological, cognitive, and social functioning up to very old age.
本文旨在研究老年人健康生活方式与身体、心理、认知和社会功能下降之间的关系。研究使用了一个基于人群的样本，包括 3107 名 55 岁和 85 岁的荷兰男女（1992/1993 年；阿姆斯特丹纵向老龄化研究），并进行了五次 3 年的随访检查。生活方式评分基于吸烟状况、饮酒量、身体活动和体重指数（BMI），范围从 0（）到 4（）。结果包括步态速度、抑郁症状、认知状态和社会联系。与没有或只有一个健康生活方式因素的人相比，具有健康生活方式的人步态速度下降速度慢 10.6%（0.04m/s，95%置信区间[CI]：[0.03，0.05]），抑郁症状增加速度慢 10.8%（-1.07[-1.70，-0.44]），认知功能下降速度慢 1.8%（0.47[0.23，0.70]），社会联系下降速度慢 4.9%（0.58[0.01，1.15]）。健康的生活方式有益于身体、心理、认知和社会功能，直至非常高龄。
