Convenience-based food purchase patterns: identification and associations with dietary quality, sociodemographic factors and attitudes.

Objective: The present study aimed to derive food purchase patterns considering the convenience level of foods. Associations between identified patterns and dietary quality were analysed, as well as household characteristics associated with the dietary patterns.

Design: A Convenience Food Classification Scheme (CFCS) was developed.

Food purchase patterns: empirical identification and analysis of their association with diet quality, socio-economic factors, and attitudes.

Background: Empirically derived food purchase patterns provide information about which combinations of foods were purchased from households. The objective of this study was to identify what kinds of patterns exist, which level of diet quality they represent and which factors are associated with the patterns.

Methods: The study made use of representative German consumption data in which approximately 12 million food purchases from 13,125 households are recorded.

Association between the Healthy Eating Index-2010 and nutrient and energy densities of German households' food purchases.

The USDA Healthy Eating Index (HEI) is used widely to measure diet quality because it allows a number of different applications. Although several evaluations of the HEI-2010 have already been carried out, there is lack of those which focus on associations between the HEI and nutrient intakes. This study updates and expands upon previous findings on these associations.
