Proper nutrition and physical exercises are essential to prevent frailty in older adults. Proper masticatory performance and oral function may influence on physical activities as well since the mouth is the entrance of nutrition and digestion. Thus, the present study aimed to test the combined program of specially devised lunch gatherings containing textured foods with oral and physical exercises on the improvement of oral and physical function in community-dwelling older adults.
A Cluster randomized controlled trial; Setting and Participants: Eighty-six community-dwelling older adults in Daito city, Japan, were randomly assigned into control (n = 43) or intervention (n = 43) groups.
The control group performed the physical exercise regimen only. The intervention group participated in a 12-week physical and oral exercise program and ate a so-called "munchy lunch" that introduced textured foods with proper nutrients together after performing the physical exercise twice a week following brief dietary instruction at the intervention onset. Physical training and lunch gatherings were held at local public centers.
The differences in measured variables for physical and oral function between baseline and 12 weeks of intervention were statistically tested.
Oral function as measured by tongue pressure increased significantly in the intervention group (p=0.031), but not in the control group. Physical properties and activities, including body fat percentage and results of the timed up and go test, decreased more significantly in the intervention group than in controls (p<0.05).
Our findings suggest that a combined program of textured lunch gatherings with oral and physical exercises may improve physical and oral function as a preventative approach for frailty in community-dwelling older adults.
适当的营养和体育锻炼对于预防老年人虚弱至关重要。适当的咀嚼性能和口腔功能也可能影响身体活动，因为口腔是营养和消化的入口。因此，本研究旨在测试专门设计的含质地食物的午餐聚会与口腔和身体锻炼相结合的方案，以改善社区居住的老年人的口腔和身体功能。
集群随机对照试验；地点和参与者：日本大府市的 86 名社区居住的老年人被随机分为对照组（n=43）或干预组（n=43）。
对照组仅进行体育锻炼方案。干预组参加了为期 12 周的身体和口腔运动计划，并在干预开始时进行两次每周的体育锻炼后，在当地公共中心一起食用所谓的“嚼劲午餐”，这种午餐引入了含有适当营养的质地食物，并在进行体育锻炼后接受简短的饮食指导。
在干预 12 周前后，对身体和口腔功能的测量变量差异进行了统计学检验。
干预组的舌压等口腔功能显著增加（p=0.031），而对照组则没有。干预组的身体物理性质和活动，包括体脂百分比和计时起立行走测试的结果，比对照组下降得更明显（p<0.05）。
我们的发现表明，含质地食物的午餐聚会与口腔和身体锻炼相结合的方案可能改善身体和口腔功能，作为预防社区居住的老年人虚弱的一种方法。
