Influence of the chewing number among middle-aged persons on their ADL and QOL

受试者被要求设置一个由长崎大学工学院开发的装置，并记录他们在吃相同体积和内容物的标准化饭盒时的咀嚼次数。 他们还测量了身体质量指数（BMI）和一般口腔健康评估指数（GOHAI）。 测量咀嚼次数与他们的BMI和GOHAI评分相关。 在日本中年人中，为了防止超重和改善与口腔健康相关的生活质量，吃得更慢，咬得更频繁将是有效的。 第一次测量后一年，再次测量受试者的体重。 但咀嚼次数与体重增长之间无显著相关性。 咀嚼次数不能估计老年人短期内的体重增长

The subjects were asked to set a device that was developed by school of engineering Nagasaki university and recorded their chewing number during eating a standardized a lunch box with same volume and contents. They were also measured their Body Mass Index (BMI) and General Oral Health Assessment Index (GOHAI). Measured chewing number was associated with their BMI and GOHAI score. To eat more slowly and bite more frequently would be effective in order to prevent over weight and improve their oral health related QOL among Japanese middle aged persons. One year after the first body measuring, subjects were measured their body weight again. However, there was not significant relationship between their chewing number and their body weight increase. Chewing number would not estimate their body weight increase in the short-term period among old aged persons
