Background:To assess the degree of gastric dilatation in patients undergoing abdominal contrast-enhanced computer tomography (CT) and to identify factors associated with gastric dilatation. Materials and Methods: This study adopted a cross-sectional design. Participants ingested water to distend the stomach 10 minutes prior to CT examination. After baseline assessment, participants self-administered the STAI under research assistant supervision. The degree of gastric dilation positively correlated with image clarity score (scale 1~5). Ordinal logistic regression analysis was used to identify influencing factors. Results: A gastric dilation score of 5 (indicating maximal dilation) was recorded in 14.0% of case, with median oral contrast volume reaching 1000ml. Ordinal logistic regression analysis confirmed five independent predictors of gastric dilation quality: education (OR=1.534, 95%CI=1.056-5.138, P=0.008), BMI(OR=4.025, 95%CI=2.284-7-092, P<0.001, water intake (OR=13.317, 95%CI 5.681-11.565, P<0.001), fasting status (OR=1.544, 95%CI=1.323-1.916, P=0.022) and ethnicity (OR=1.679, 95%CI=1.311-1.916, P=0.023). Inter-reader agreement was excellent (ICC=0.943). Conclusions: In individuals who underwent abdominal contrast-enhanced CT, the general state of stomach filling was poor. The education level, dietary intake, the consumed amount of water, BMI and ethnicity contributed to gastric dilatation.
