Questionnaires are typically used for collecting information
describing health behavior in areas such as diet, physical activity and sleep.
Utilization of the digital footprint, formed from an individual’s unique digital
activities, forms a potential new opportunity for describing lifestyle and
health-related behavior. We studied if passively collected shopping data
describes food intake when compared to food frequency questionnaire (FFQ)
data providing information on food and beverage consumption. For 4 out of 21
food groups the results were comparable. Shopping information from only one
department store chain gives only a partial picture of the food consumption and
differing family sizes add noise to the estimate. If the whole digital footprint
would be available, including detailed product-level shopping information from
all stores and restaurants, the food intake could probably be estimated more
accurately and applied e.g. in personalized coaching.
