How does education affect diet in women? A comparison between Central and Southern Europe cohorts


 
 
 Comparisons among European populations is useful to identify opportunities for planning nutrition strategies to reduce social inequalities in health. Our study aims to identify dietary patterns in adult women and to evaluate their association with educational level in Czech Republic and Italy, which display different health inequalities.
 
 
 
 We performed a cross-sectional analysis of women (aged 25-64 years) with no history of severe diseases, who have been recruited in Brno (Czech Republic; n = 957) and in Catania (Italy; n = 841). Dietary patterns were derived by Food Frequency Questionnaire and Principal Component Analysis. We tested the association between educational level (low vs. high) and adherence to dietary patterns. Logistic regression models were used to assess Odds ratio (OR) and 95% confidence interval (CI), after adjusting for age, employment status, marital status, smoking status, parity, BMI, and menopause.
 
 
 
 In both cohorts, we identified the healthy and the unhealthy dietary patterns. We observed that women with high adherence to the healthy dietary pattern were less educated in Czech Republic, and more educated in Italy. After adjusting for covariates, low educational level was positively associated with adherence to the healthy dietary pattern among Czech women (OR = 2.033; 95%CI=1.301-3.176; p = 0.002), and negatively associated among Italian women (OR = 0.166; 95%CI=0.029-0.952; p = 0.044). No association was identified between educational level and the unhealthy dietary pattern.
 
 
 
 In the Italian cohort, findings were consistent with the notion that healthy dietary choices are less common among low-educated groups. By contrast, in newly developed countries such as the Czech Republic, the “nutrition transition” from traditional staples to western foods might be more common in highly-educated groups, probably due to the advocacy of Western culture through mass media and commercial marketing.
 
 
 
 Low educational level has an opposite effect on healthy diet, exhibiting a positive association in Czech women, and a negative association in Italian women. From a broader perspective, the observed effect of education on diet quality helps explain social health inequalities in Central and Southern Europe.
