编辑先生，由于认知障碍，老年人的生活质量(QOL)显著下降，因此，显然需要有效的干预措施来减少这种损失。集体锻炼不仅改善了健康老年人的身体和认知功能，而且还改善了他们的生活质量。此外，它还为社交提供了机会，这可能会对生活质量产生积极影响，因为频繁的社交活动与认知衰退的速度较慢有关。到目前为止，还没有研究表明集体锻炼是否可以改善患有轻度认知障碍(MCI)的老年人的生活质量。我们之前发现，参加团体多成分锻炼计划对患有MCI的老年人的认知功能有积极影响。在这项研究中，我们研究了集体锻炼是否对患有MCI的老年人的生活质量产生了积极的影响。随机对照试验的方案和设计已经在前面描述过了。100名符合彼得森MCI标准的参与者在基线评估后被分配到运动组或教育控制组。国家老年医学和老年学中心伦理委员会(OBU，日本)批准了该研究方案。所有受试者在参与前都给予书面知情同意。我们使用医疗结果研究八项简明健康调查(SF-8)，一份包含八项的问卷，评估生活质量概况。这项调查着眼于以下健康领域：身体功能、角色限制--身体、身体疼痛、一般健康、活力、社交功能、角色限制--情感和心理健康。为期12个月的多项运动计划包括每周两次90分钟的训练，内容包括有氧运动、耐力步行、肌肉力量训练、姿势平衡再训练、步行训练和组合训练。运动组参与者被鼓励在家中进行自我指导的练习，并与组成员讨论他们的成就水平。对于运动组和控制组之间的基线比较，采用学生t检验或χ检验来检验连续变量。分析是在意向治疗的基础上进行的；没有完成计划的受试者在6个月和12个月时缺失的数据被每个时间点的平均测试值取代。比较两组在三个时间点(基线、6个月和12个月)的SF-8评分，采用双向重复测量方差分析。统计学意义为P<；0.05。DOI：10.1111/心理。12165老年精神病学2016年；··：··-··
Dear Editor, Quality of life (QOL) among the elderly decreases dramatically with cognitive impairments, and therefore, there is a clear need for effective interventions to reduce such loss. Group exercise improves not only physical and cognitive function, but also QOL in healthy older adults. Furthermore, it provides an opportunity for social interaction, which may have a positive effect on QOL, as frequent social activity has been associated with slower rates of cognitive decline. To date, no studies have examined whether group exercise can improve QOL in older adults with mild cognitive impairment (MCI). We previously found that participation in a group multicomponent exercise programme had a positive impact on cognitive function in older adults with MCI. In the present study, we examined whether group exercise exerted a positive effect on QOL in older adults with MCI. The protocol and design of the randomized controlled trial have been previously described. One hundred participants meeting the Petersen criteria for MCI were allocated to an exercise group or an education control group after a baseline assessment. The Ethics Committee of the National Center for Geriatrics and Gerontology (Obu, Japan) approved the study protocol. All subjects gave written, informed consent before participation. We used the Medical Outcome Study eight-item Short-Form Health Survey (SF-8), an eight-item questionnaire, to assess QOL profiles. The survey looked at the following health domains: physical functioning, role limitations– physical, bodily pain, general health, vitality, social functioning, role limitations–emotional, and mental health. The 12-month multicomponent exercise programme consisted of 90-min sessions twice weekly involving aerobic exercise, endurance walking, muscle strength training, postural balance retraining, walking training, and combination training. Exercise group participants were encouraged to perform selfdirected exercises at home, and their level of achievement was discussed with the group. For baseline comparisons between the exercise and control groups, continuous variables were examined with Student’s t-tests or χ tests. Analysis was on an intention-to-treat basis; data missing at 6 and 12 months for subjects who did not complete the programme were replaced with the mean test values for each time point. SF-8 scores at three time points (baseline, 6 months, and 12 months) in each group were compared with a two-way repeatedmeasures ANOVA. Statistical significance was set at P < 0.05. doi:10.1111/psyg.12165 PSYCHOGERIATRICS 2016; ••: ••–••
