Does a population-based multi-factorial lifestyle intervention increase social inequality in dietary habits? The Inter99 study

► Individuals with low socioeconomic position (SEP) have in general less healthy dietary habits than individuals with high SEP. ► It has been discussed, but is unclear from the scientific literature, if the social inequality in dietary quality will actually increase by giving individualised lifestyle counselling. ► Surprisingly participants with low SEP improved their dietary habits relatively more than participants with high SEP. ► The results indicate that a population-based multi-factorial lifestyle intervention may reduce social inequality in dietary habits.
