Education- and income-related differences in processed meat consumption across Europe: The role of food-related attitudes.

Purpose: Dietary behaviors differ between socio-economic groups and are one key determinant of health inequalities. Psychological factors such as attitudes are assumed to underlie the relation between inequality and dietary behaviors, but this assumption has rarely been tested empirically. We focus on a specific food group shown as detrimental to health: processed meat.
Methods: In two representative international surveys (Survey 1: N = 10,226 participants from nine European countries - Austria, France, Germany, Italy, Netherlands, Poland, Russia, Spain, UK; Survey 2: N = 9149 participants from the same countries, except not including Austria and the Netherlands), participants reported inequality indicators (education, income), processed meat consumption as well as their attitudes toward nutrition and food.
Principal Results: There were diverging relationships between indicators of inequality and processed meat consumption: the higher the educational attainment, the lower the consumption of processed meat (r _Survey1  = -0.062, p < .001; r _Survey2  = -0.071, p < .001). At the same time, higher income was related to higher processed meat consumption (r _Survey1  = 0.088, p < .001; r _Survey2  = 0.152, p < .001). A path model showed that four of seven attitude factors mediated the relation between education and processed meat consumption (i.e., indifference toward nutrition and food, preference for regional and fresh food, processed food consumption, health efforts); none of the attitude factors mediated the relation between income and overall processed meat consumption.
Conclusions: Processed meats are consumed very frequently across European countries. The relation between inequality and processed meat consumption is heterogeneous and partially mediated by attitudes. More research is needed to better understand how psychological factors explain social inequality in nutrition behaviors and health in general.
