Abstract

Assessing the dietary intake is quite technical component of determining the overall nutritional status of people. There are several dietary assessment tools available for gathering data on dietary intake. However, the food consumption being a complicated human behavior makes it difficult to state the validity of these tools. Recent advances in application of computer methods in health sector have led to focusing on technology in gathering diet related data. There can be some feasibility issues that may hamper the practicality of these technologies in contextual usage. Unavailability of local food data base and portion sizes make it difficult to use in specific areas. This study was designed to establish a protocol for an image based, digital dietary assessment tool and test its validity against the simplified version of same tool (24 hour recall [24HR]). This paper presents the prototype for PakNutriStudy, Pakistan. A digitalized version of 24HR was developed with incorporation of local features. The tool aims at reducing the biases and errors that arise during dietary data collection. We expect that the two versions would yield comparable results and that technological advancements can offer promising outcomes for better quality dietary assessment.
