Data processing using DINER and DINERMO: introduction

A series of programs and databases that constitute the DINER program has been developed at EPIC-Norfolk to convert 7DD or 24HR information into structured data for nutrient analysis. Trained data enterers code the data from food diaries according to specified guidelines by selecting items from the extensive food list within DINER (nearly 11,000 items) and entering the associated portion size and any other information. DINER allows food intake and the amount consumed to be translated exactly as recorded in the original diary.

DINERMO consists of further programs and databases which translate the structured data into weights of food and nutrient data for analysis.

 

When EPIC-Norfolk began in 1993, there were no data entry and nutrient analysis systems suitable for a large-scale study with a long period of data collection. A system was needed that would be robust enough to deal with the changes that would occur within the food supply over time and also to investigate the many hypotheses of interest. Systems available in 1993 were unable to record sufficient detail, as they were based on the limited number of food types available within the available national food composition databases. The range of published portion sizes was also limited. Extensive databases have had to be developed and maintained to support DINER and DINERMO. All databases can be updated and extended as new data becomes available without the re-coding of food records.
