Abstract
Objectives
This study assessed the impact of education on diet and compliance with the national recommendations.
Methods
The study included 4338 adult participants of the Colaus study, a cross-sectional, population-based study conducted between 2009 and 2012 in Lausanne (Switzerland). Education was categorized as primary, apprenticeship, secondary, and tertiary.
Results
Men with primary vs. tertiary education had a lower intake of monounsaturated fatty acids (29.4 vs. 30.9 g/day), iron (11.4 vs. 11.8 mg/day), vitamin A (758.2 vs. 904.2 retinol equivalents/day), and vitamin D (2.3 vs. 3.0 μg/day). Women with primary vs. tertiary education had a lower intake of monounsaturated fatty acids (25.5 vs. 27.4 g/day), fiber (15.6 vs. 17.2 g/day) and iron (9.8 vs. 10.3 mg/day). Men with primary vs. tertiary education had a better compliance with protein recommendations [odds ratio (95 % CI): 2.31 (1.37; 3.90)], while women with primary vs. tertiary education had a better compliance with vitamin A recommendations [odds ratio 1.74 (1.15; 2.65)].
Conclusions
Overall, our results do not confirm a unidirectional association between education and diet, and question the approach of targeted interventions alone in selected educational groups to prevent chronic diseases.
