The aim of this randomized controlled pilot study is to describe the effects of a physical training and nutritional intervention program on the physical activity level and activities of daily living (ADL) in frail elderly people. Ninety-six community-dwelling frail elderly people (58 women) above the age of 75 were included in the study. The 12-week physical and/or nutritional intervention program was followed by six months of home-based exercises for the training groups, followed up with training diaries. At baseline the subjects were screened for physical activity level, walking habits, and ADL. These measurements were repeated immediately after the intervention at 3 months, and at 2nd follow-up at 9 months. ADL data were also collected 24 months after baseline at 3rd follow-up. The intention-to-treat analyses showed an increase of the habitual physical activity level and walking duration at 1st follow-up for the two training groups compared to the other groups. These increases remained at 2nd follow-up. The nutrition intervention did not show any significant results. No significant effects on ADL were shown however, there were moderate correlations between increases in physical activity level and ADL as well as between the amounts of home-based exercises and ADL for the two training groups.
本随机对照初步研究的目的在于描述一项身体训练和营养干预计划对虚弱老年人身体活动水平和日常生活活动（ADL）的影响。96 名居住在社区的虚弱老年人（58 名女性）年龄超过 75 岁，纳入本研究。为期 12 周的身体和/或营养干预计划后，为训练组提供为期 6 个月的家庭锻炼，并进行训练日记记录。在基线时，对受试者的身体活动水平、行走习惯和 ADL 进行筛查。这些测量在干预后立即在 3 个月时、第 2 次随访时在 9 个月时进行重复。ADL 数据还在基线后 24 个月时的第 3 次随访时进行收集。意向性治疗分析显示，与其他组相比，两组训练组在第 1 次随访时的习惯性身体活动水平和行走时间增加。这些增加在第 2 次随访时仍然存在。营养干预并未显示出任何显著结果。然而，对于 ADL 并未显示出显著影响，但两个训练组的身体活动水平增加与 ADL 之间以及家庭锻炼量与 ADL 之间存在中度相关性。
