Background: Good nutrition during pregnancy is critical for optimal maternal and neonatal outcomes1-3.There are a lack of studies investigating the dietary intake of pregnant women in Australia, and more specifically, in areas of high-risk for obesity and nutritional deficiencies such as Western Sydney4.
Aim: The aim of this study was to collect the self-reported dietary intake data of pregnant women attending Nepean hospital and compare findings with existing published data.
Method: A survey was designed to collect current dietary intake of pregnant women, including self-reported anthropometric measures, dietary intake, food security and food safety questions. After giving informed consent, participants chose to complete the survey, either on paper or electronically. Descriptive analysis was performed using Excel to describe the cohorts under study. The number and percentage of women meeting national recommendations were determined and compared with published data5-8. Common dietary changes made on establishment of pregnancy were grouped and reported.
Results: A total of 195 participants were recruited for the study over 5 consecutive days in January 2019. The results are displayed in Tables 1, 2 and 3. More than half of pregnant women reported dietary changes after pregnancy. The common changes included eating healthier diets, avoiding unsafe foods (e.g. soft cheeses) and decreasing carbohydrate consumption (with a few participants reported on keto diets).

Discussion: The study revealed the dietary intake of pregnant women in a western Sydney antenatal clinic. Overall, it showed that their intake was inadequate in nutrition, when compared to national recommendations.
