In order to develop Evidence Based Nutrition (EBN), it is important to conduct a reliable assessment of dietary intake and to examine the effectiveness of dietary education through a randomized controlled trial. This paper mainly describes two important issues. The one is the assessment of the validity and reproducibility of a self-administered food frequency questionnaire as a tool for assessing appropriate dietary intake. Another is the approach for examining the effectiveness of dietary education for a practical nutrition education study based on EBN. Through the empirical studies, we suggest the importance of promoting effective nutrition education method based on the scientific basis.
To provide effective nutrition education for improving behavioral change on subject's lifestyle, type specific education may be effective. The aim of the study is to classify the subjects into several types based on their behavioral pattern. In total, 270 outpatients in clinics who underwent nutrition counseling were the subjects of this study. The assessment questionnaire consists of 14 items including questions of awareness of their illness, willingness to change their lifestyle. Hayashi's quantification method 3 was used (Q3) to examine the response pattern. As a result, the outpatients were classified into four types based on the analysis by Q3 and we proposed an approach corresponding to each type. Possibility to classify the patients into the four types with less items was examined by correlation coefficients. Short version of assessment using four items was suggested to be practically useful. The adequate approach for each type is expected to increase the effectiveness of nutrition education compared to the conventional nutrition education that is based on nutritionist own experience. Further study is needed to examine the effectiveness of this method.
In this report, we show the process, the feature, and the outline of the personalized health education program based on a behavior metrics approach. According to the program, we conducted the health education for 6 months for the subjects of specific health guidance for “motivational support” and “active support”. The changes from baseline of weight, waist circumference, consciousness and behavior were examined including a trial to perform Adachi's Type Specific Education. From the results, feasibility of the type specific education was suggested. In the discussion, issues for further study was discussed.
In this report, we analyzed the effectiveness of our measure in streamlining national registered dietitians' work process in a nutritional support team (NST). After introducing the measure to improve the identification of various oral nutritional supplements (ONS), the occupancy rate of ONS explanation by dieticians' work process during NST inspection was reduced from 22.2% to 5.5%. Furthermore, the average monthly prescription of ONS to patients increased. This measure not only streamlined dieticians' work process but also encouraged the nurses to participate in nutritional management.
