Abstract

OBJECTIVE

To investigate the effects of an aerobic dancing program on sleep quality of older adults with mild cognitive impairment (MCI) and poor sleep.

DESIGN

The study adopted a single-blinded randomized controlled trial design.

SETTINGS AND PARTICIPANTS

Community-dwelling adults older than 60 years screened with the coexistence of MCI and poor sleep were included. A total of 89 eligible participants were randomly assigned to receive either the aerobic dancing program or the health education attention placebo control group.

METHODS

The primary outcome was sleep quality, which was measured by the Pittsburgh Sleep Quality Index. The second outcome was cognitive function, which was assessed by the Montreal Cognitive Assessment. Analysis followed the intention-to-treat principle. Generalized estimating equation was adopted to compare the changes in outcomes over the pre-post test periods between groups.

RESULTS

The average adherence rate of the exercise program was 73.1%. No adverse events occurred during the study period. Participants in the intervention group had a significantly greater improvement in terms of general sleep quality (β, -1.74; 95% CI, -3.41 to -0.08; P = .04), sleep latency (β, -0.19; 95% CI, -0.37 to -0.02; P = .03), sleep duration (β, 0.51; 95% CI, 0.24 to 0.99; P = .04), sleep efficiency (β, 0.11; 95% CI, 0.07 to 1.12; P = .04), and cognitive function (β, 1.64; 95% CI, 0.43 to 2.86; P = .008) compared with the control group over the pre-post test periods.

CONCLUSIONS AND IMPLICATIONS

This study demonstrated that a 16-week aerobic dancing program is feasible and effective in improving sleep quality and cognitive function among older adults with coexistence of MCI and poor sleep. The feasibility and effectiveness of this exercise program promoted the need to increase its application against deteriorating poor sleep and cognitive decline in older adults with MCI.

摘要

目的

探讨有氧舞蹈项目对轻度认知障碍（MCI）且睡眠质量差的老年人睡眠质量的影响。

设计

本研究采用单盲随机对照试验设计。

设置与参与者

纳入年龄在60岁以上、经筛查并存MCI和睡眠质量差的社区居住成年人。共有89名符合条件的参与者被随机分配接受有氧舞蹈项目或健康教育关注安慰剂对照组。

方法

主要结局为睡眠质量，采用匹兹堡睡眠质量指数进行测量。第二个结局为认知功能，通过蒙特利尔认知评估进行评估。分析遵循意向性分析原则。采用广义估计方程比较组间前后测试期结局的变化。

结果

运动项目的平均依从率为73.1%。研究期间未发生不良事件。与对照组相比，干预组在前后测试期的总体睡眠质量（β，-1.74；95%CI，-3.41至-0.08；P = .04）、睡眠潜伏期（β，-0.19；95%CI，-0.37至-0.02；P = .03）、睡眠时间（β，0.51；95%CI，0.24至0.99；P = .04）、睡眠效率（β，0.11；95%CI，0.07至1.12；P = .04）和认知功能（β，1.64；95%CI，0.43至2.86；P = .008）方面有显著更大的改善。
