Socio-economic circumstances and food habits in Eastern, Central and Western European populations

Objective: To assess the relationship between several socio-economic indicators and frequency of consumption of seven predefined healthy foods (consumption of fruit, vegetables, wholegrain bread, vegetable-fat spread, vegetable cooking fat, low-fat milk and low-fat cheese) in populations from Eastern, Central and Western Europe. Design: Analysis of baseline data collected in two cross-sectional cohort studies between 2000 and 2005: the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) study and the Finnish Helsinki Health Study (HHS). Setting: Urban populations in the Czech Republic, Russia, Poland and Finland. Subjects: In the HAPIEE study, random samples of men and women aged 45-69 years were drawn from population registers and electoral lists of selected cities. In the HHS, men and women aged 40-60 years employed by the City of Helsinki were recruited. Data on 21 326 working subjects from both cohorts were analysed. Results: Healthy food habits were, in general, positively associated with higher education, occupational position and fewer economic difficulties, but there were differences in the strength of the gradient by food and country. Fruit consumption showed the most consistent gradients, especially in relation to socio-economic status among men (country-specific relative index of inequality (RII) =2.02-5.17) and women (RII=2.09-3.57). Conclusions: The associations between socio-economic indicators and healthy food habits showed heterogeneity between countries. Future studies of dietary behaviours should consider multiple measures of socio-economic position.
