Background: Studies on the association between vegetarian diets and nonalcoholic fatty liver disease (NAFLD) are limited and have inconsistent results. This study aims to explore the association between vegetarian diets and NAFLD and compare the stage of fibrosis between vegetarians and nonvegetarians in a US representative sample. Methods: Cross‐sectional data from 23,130 participants aged ≥20 years were obtained from the National Health and Nutrition Examination Survey, 2005–2018. Vegetarian status was classified based on two 24‐h dietary recalls. We examined the association between vegetarian diets and the risk of NAFLD using the propensity score weighting method. Results: Vegetarian diets were significantly associated with decreases in hepatic steatosis index (HSI), US fatty liver index and nonalcoholic fatty liver disease fibrosis score with mean differences of −2.70 (95% confidence interval [CI]: −3.69, −1.70), −3.03 (95% CI: −7.15, −0.91) and −0.12 (95% CI: −0.26, −0.01), respectively. While modelling the risk of NAFLD, we estimated that vegetarians were 53% less likely to have NAFLD assessed by HSI (odds ratios [OR]: 0.47; 95% CI: 0.34, 0.65). The effect of vegetarian diets was higher among individuals with lower waist circumferences (OR: 0.20) than among those with higher waist circumferences (OR: 0.53, pinteraction ${p}_{\text{interaction}}\,$= 0.004). However, the association was largely attenuated after adjusting for body mass index and diabetes status. No significant association was identified between vegetarian diets and advanced fibrosis. Conclusions: Vegetarian diets were associated with a lower prevalence of NAFLD among US adults, and the association appeared to be stronger in people with lower waist circumferences. Further studies are warranted to replicate our findings. Key points: Vegetarians had low risks of nonalcoholic fatty liver disease (NAFLD) development.A stronger association was observed among people with lower waist circumferences.Vegetarians were observed to have lower degrees of fibrosis among people with NAFLD.Future nutritional interventions may prioritise a low‐inflammatory dietary plan.

I Background: i Severe maternal morbidity (SMM) during hospitalizations for deliveries affects more than 50 000 U.S. women annually, with risks for long-term morbidity and immediate health care costs more than double that of unaffected deliveries ([1], [2]). I Objective: i To compare delivery hospitalization costs between rural and urban residents by SMM status and degree of complexity (no SMM, any SMM, 1 SMM, and >=2 SMMs). To compare cost between rural and urban residents, multivariable generalized linear models were applied using a gamma distribution with a log-link function within 4 strata of SMM status and complexity: no SMM, any SMM, 1 SMM, and 2 or more SMM indicators.
