Randomized Trial of Exercise and Social Interaction in a Community-Based Sample of Non-Demented Chinese Elders (SCIBHI)
2012年9月27日 更新者：University of South Florida
A Pilot Randomized Intervention Study of Physical Exercise and Social Engagement in Chinese Elders
A pilot randomized clinical trial was conducted in a random sample of 120 non-demented Chinese elders (ages 60-79) living in a defined community in Shanghai, China to compare the effects of interventions (fast walking, Tai Chi, group intellectual discussion) to no intervention with respect to change in cognition and whole brain volume determined by repeated neuropsychological batteries and MRI scans.
Aims included determining the feasibility of recruiting and retaining a random sample of people age 60+ for such a trial as well as collection of preliminary data on the efficacy of the interventions.
The long-term goal of this research program is to determine whether sustained physical and/or mental exercise interventions are efficacious in delaying the onset of dementia and to understand the role and mechanisms of brain growth in this process.

詳細な説明
Physical exercise has been shown to increase brain volume and improve cognition in randomized trials of non-demented elderly.
Although greater social engagement was found to reduce dementia risk in observational studies, randomized trials of social interventions have not been reported.
A representative sample of 120 elderly from Shanghai, China was randomized to four groups (Tai Chi, Walking, Social Interaction, No Intervention) for 40 weeks.
Two MRI's were obtained, one before the intervention period, the other after.
A neuropsychological battery was administered at baseline, 20 weeks and 40 weeks.
Comparison of changes in brain volumes in intervention groups with the No Intervention group were assessed by t-tests.
Time-intervention group interactions for neuropsychological measures were evaluated with repeated-measures mixed models.

実験的：Fast walking
Participants assigned to this group met with two group leaders three times per week in the morning in Jing An Park and were encouraged to walk quickly around a 400 meter circular route.
Each session consisted of 10 minutes of warm-up stretching, 30 minutes of brisk walking, and 10 minutes of cool-down exercises.
Prior to the first session, each participant was given a pedometer with their name on it.
They were asked to take 100 steps and the sensitivity and positioning of the pedometer was adjusted to assure accurate measurement.
At the termination of each session, the pedometers were collected and the number of steps taken by each participant at that session recorded.
A record of the number of steps taken for every participant at each session over the 40 week period was maintained.

アクティブコンパレータ：Tai Chi
Participants assigned to this group met with a Tai Chi master and assistant three times per week in the morning in Jing An Park or at a nearby gymnasium depending on weather conditions.
Each session included 20 min of warm-up exercises (lower back and hamstring stretching, gentle calisthenics, and balance training), 20 min of Tai Chi practice, and 10 min of cool-down exercises.

アクティブコンパレータ：Intellectual stimulation
Participants assigned to this group met with a group leader and an assistant for one hour three times a week in the morning at the neighborhood community center.
Although direction was initially given regarding subjects for discussion, the participants decided on their own to organize and select topics themselves.

プラセボコンパレーター：Contact and testing only
The fourth group received no intervention.
Contact was maintained by phone during the intervention period to reduce dropout.
Participants were called four times during the 40 weeks intervention period by the study coordinator.
