Dietary Intake of Pregnant Women with and without Inflammatory Bowel Disease in the United States.

Abstract

Pregnancy is a vulnerable time where the lives of mother and baby are affected by diet, especially high-risk pregnancies in women with inflammatory bowel disease (IBD). Limited research has examined diet during pregnancy with IBD. Describe and compare the diet quality of pregnant women with and without IBD, and examine associations between dietary intake and guidelines during pregnancy. Three 24 h recalls were utilized to assess the diets of pregnant women with IBD (n = 88) and without IBD (n = 82) during 27-29 weeks of gestation. A customized frequency questionnaire was also administered to measure pre- and probiotic foods. Zinc intake (p = 0.02), animal protein (g) (p = 0.03), and ounce equivalents of whole grains (p = 0.03) were significantly higher in the healthy control (HC) group than the IBD group. Nutrients of concern with no significant differences between groups included iron (3% IBD and 2% HC met the goals), saturated fat (only 1% of both groups met the goals), choline (23% IBD and 21% HC met the goals), magnesium (38% IBD and 35% HC met the goals), calcium (48% IBD and 60% HC met the goals), and water intake (49% IBD and 48% HC met the goals). Most pregnant women in this cohort fell short of the dietary nutrients recommended in pregnancy, especially concerning for women with IBD.
