A more convenient approach would enable researchers to perform analyses online, without the need to coordinate additional analysis tools. This paper presents a system illustrating such an approach, using as a testbed the WAVE project, which is a 5-year childhood obesity prevention initiative being conducted at Oregon State University by health scientists utilizing a web application called WavePipe. This web application has enabled health scientists to create studies, enrol subjects, collect physical activity data, and collect nutritional data through online surveys. This paper presents a new sub-system that enables health scientists to analyse and visualize nutritional profiles based on large quantities of 24-hour dietary recall records for sub-groups of study subjects over any desired period of time. In addition, the sub-system enables scientists to enter new food information from food composition databases to build a comprehensive food profile. Interview feedback from novice health science researchers using the new functionality indicated that it provided a usable interface and generated high receptiveness to using the system in practice.
