<p><b>PURPOSE: </b>To (1) assess dietary intakes of pregnant women with previous bariatric surgery in comparison with Dietary Reference Intakes (DRIs); (2) compare their dietary intakes as well as their diet quality with a control group of pregnant women with no history of bariatric surgery.</p><p><b>METHODS: </b>Twenty-eight (28) pregnant women with previous surgery (sleeve gastrectomy, n = 7 and biliopancreatic diversion with duodenal switch, n = 21) were matched for pre-pregnancy body mass index with 28 pregnant women with no history of bariatric surgery. In at least one trimester, participants completed a minimum of 2 Web-based 24-h dietary recalls from which energy, macro- and micronutrient intakes as well as the Canadian Healthy Eating Index (C-HEI) were derived.</p><p><b>RESULTS: </b>No differences were observed for energy intake between groups. All women had protein intakes within the recommended range, but most women with previous surgery had carbohydrate (67%) and dietary fiber intakes (98%) below recommendations. In both groups, mean total fat, saturated fatty acids, free sugars and sodium intakes were above recommendations, as opposed to mean vitamin D, folic acid and iron dietary intakes below recommendations for most women. Compared with the control group, pregnant women with previous bariatric surgery had lower overall C-HEI scores.</p><p><b>CONCLUSION: </b>These results suggest that pregnant women with previous bariatric surgery would benefit from a nutritional follow-up throughout their pregnancy.</p><p><b>LEVEL OF EVIDENCE: </b>III: Evidence obtained from well-designed cohort or case-control analytic studies.</p>
