Social determinants of dietary habits in Denmark

Objective: To investigate whether there is an association between socioecon omic status and a healthy diet, taking the possible influence of other soci al variables such as age, gender, income and household composition into con sideration. Design: Cross-sectional study. Setting: Nationwide study in Denmark, 1995. Subjects: Random sample from the civil registration system. A total of 852 men and 870 women aged 18-80y participated, a response rate of 58%. Interventions: A 7 day estimated dietary record was used to obtain informat ion about the diet. Information about social background was gained through face-to-face interview. Results: The intake of fruit and vegetables and the percentage energy (E%) from fat in the diet were significantly associated with the educational lev el of both men and women. For men with only basic schooling, the mean intak e of vegetables and fat was 84 g/10 MJ and 41 E% respectively. Men with lon g higher education had a mean intake of 119 g/10 MJ of vegetables and 37 E% of fat. For women, the corresponding figures for the intake of vegetables and fat were 131 g/10 MJ and 38 E% and 175 g/10 MJ and 37 E%, respectively. For women, age, income and household composition were also significantly a ssociated with the intake of fruit and vegetables.
