What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Nutritional Quality of Food Purchases
Time Frame: Participants were followed for one shopping session, an average of 2.5 hours
The Overall Nutrient Quality Index (ONQI) was used to assess nutritional quality of foods purchased. The ONQI is a 1 - 100 scale in which higher numbers indicate higher nutritional quality. Each food is given a score based on a ratio with positive health nutrients in the numerator and detrimental health nutrients in the denominator, based on a proprietary algorithm created by NuVal. The average ONQI score for all the groceries purchases was used as the outcome measure, of ONQI scores on a scale.
Participants were followed for one shopping session, an average of 2.5 hours
