Type of delivery lacks the association with dietary patterns followed by pregnant women in their third trimester.

Background: Maternal nutrition plays a crucial role in fetal development, women's health, and reproductive capacity. Dietary pattern (DP) is a measure of overall diet and has become widespread in nutrition research as an alternative method to studying individual components of the diet. Aim: this study aims to determine the adopted DPs by Jordanian pregnant women and evaluate their potential associations with the mode of delivery. Methods: A cross-sectional study included 249 healthy Jordanian pregnant women in their third trimester of pregnancy who attended antenatal clinics at Jordan University. Personal information was gathered using a pre-tested structured questionnaire. To investigate dietary patterns, a valid and reliable food frequency questionnaire was employed, and a pregnant physical activity questionnaire was used to estimate physical activity levels. The mode of delivery data was collected from the medical records after delivery. Results: The majority of pregnant women (82.3%) fell within the age range of 20 to 35 years. Notably, 34.5% of the mothers were classified as overweight or obese. Additionally, around one in five deliveries involved emergency cesarean sections. Four distinct DPs were identified and labelled as "fruit and vegetables", "healthy", "traditional", and 'fat and sugar" dietary patterns. However, no significant association was found between these identified dietary patterns and the occurrence of Caesarean section (CS) across all tertiles. Conclusion: The analysis revealed no substantial protective effect of the DPs against the occurrence of CS across all tertiles of dietary patterns. However, further studies are needed to either confirm or challenge our findings.
