| Research Abstract |
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
