Fig 1.
Demography characteristics of estimated US adult population with inflammatory bowel disease (IBD) from National Health Interview Survey (NHIS), 2015.
(A) IBD prevalence (%) in sample US adult survey participants and estimated US adult population. B) Distribution of gender, poverty status, and ethnicity shown in percentages. (C) Age, (D) race, (E) regions of residence, and (F) education. Values in panels C, D, E, and F reflect those of IBD population. Error bars indicate lower and upper bound of 95% confidence interval. N = (Number of people with IBD/Total number) *Asterisks indicate statistically significant difference (p-value < 0.05) when compared to estimated non-IBD population.
Fig 2.
Lifestyle characteristics of estimated US adult population with inflammatory bowel disease (IBD) from National Health Interview Survey (NHIS), 2015.
(A) Alcohol user status, (B) alcohol consumption status, (C) smoking, and (D) Body Mass Index (BMI, kg/m2). Values in panels A, B, C, and D reflect those of IBD population. Error bars indicate lower and upper bound of 95% confidence interval. N = (Number of people with IBD/Total number) *Asterisks indicate statistically significant difference (p-value < 0.05) when compared to estimated non-IBD population. K-Kindergarten; HS-High school; GED -General Education Development.

Comparison of weighted proportion of food intake between estimated US population with IBD and without IBD, NHIS 2015.
Values in panels A, B, C, and D reflect those of IBD population. *Asterisks indicate statistically significant difference (p-value < 0.05) when compared to estimated non-IBD population.

This figure does not imply or establish causal relationship of food items assessed with IBD. The picture only depicts general association found in this current study.
