Results of two models : EU label (p = 0.005; p = 0.005) and TL label (p = 0.011; p = 0.022)3.0
Grunert, Fernández-Celemín, et al., 2010 UK, Sweden, France, Germany, Poland, HungaryFOP labels in Europe including: GDA Color-coded GDA TL Keyhole (Sweden only)In-store observation, in-store interview, and in-home questionnaire in six European countries. In UK and Sweden, 3 retailers x 3 locations x 6 product categories. In France, Germany, Poland, and Hungary, 2 retailers x 3 locations x 6 product categories. Use and understanding of GDA FOP nutrition labels measured via in-home questionnaire. Regarding understanding, subjects were presented with GDA and asked to indicate healthier food. When respondents were asked to choose the healthiest product for 3 ready meals, all products tested for all countries included the GDA label except Sweden. (In Sweden tested Keyhole label.)For in-store observations and interviews, 2,019 shoppers recruited in UK, 1,858 Sweden, 2,337 France, 1,963 Germany, 1,800 Poland, and 1,804 Hungary. Subjects recruited via retail store intercept. Same respondents for the in-home questionnaires. However, return rates were 46% UK, 65% Sweden, 36% France, 42% Germany, 83% Poland, and 39% Hungary.

Subjects did not consult TL, health logo, specific nutrition claims, or colored-GDA as frequently. Use increases with social grade (several p-values listed for different grades) and interest in healthy eating (p < 0.0001).3.0
