Background: Looking at the overall diet quality, through dietary patterns, is believed to represent a valid and meaningful measure of the overall nutrient intake and is a promising approach when studying diet related associations. The aim of the study was to evaluate the correlates of maternal diet during pregnancy. Methods: The analysis is based on the data from Polish Mother and Child Cohort (REPRO_PL). During the second trimester of pregnancy 1318 women filled in the Food Frequency Questionnaire (FFQ). In the questionnaire the women were asked to report how often, on average, they consumed specified amounts of each food. The selected frequency category for each food item was converted into the daily intake. Based on the factor analysis two dietary patterns were identified. ‘Healthy dietary pattern’ was characterized by a high intake of fish, chicken, wholegrain products, fruit and vegetables, while ‘unhealthy dietary  pattern’ was related to a high intake of processed food, high-fat dairy, refined grains and sweets. Results: ‘Healthy dietary pattern’ was represented more frequently by the older (p=0.05), married women (p=0.03) and  those who declared a higher level of education (p≤0.001) and a higher socio-economic status (p=0.01). In the group of women that could be classified based on BMI as overweight or obese (≥25kg/m2) 23% of them represented ‘unhealthy”  and 37% ‘healthy’ style of eating (p=0.015). Pregnancy weight gain was not a significant correlate of maternal diet (p=0.3). The women who were classified as smokers during pregnancy reported ‘unhealthy dietary pattern’ more frequently than the non-smokers did (p=0.02).  Conclusions: The study results highlight the need for educational programs and interventions focusing on the diet quality and consumption of healthy food during pregnancy.
