Abstract
BACKGROUND
Non-alcoholic fatty liver disease (NAFLD) and gastroesophageal reflux disease (GERD) are both associated with obesity. However, the relationship of NAFLD with reflux esophagitis (RE) is still unclear in non-obese individuals.
METHODS
Individuals with a body mass index (BMI) of 28 kg/m2 or higher, as well as waist circumference (WC) no less than 90 cm for men and no less than 85 cm for women were excluded. After controlling for other factors, 1905 eligible adult subjects were included. The components related to metabolic syndrome and the prevalence of NAFLD in the RE group as well as the non-RE group were analyzed. Risk factors for RE were determined using logistic regression.
RESULTS
In non-obese individuals, the prevalence of RE and NAFLD increased with increasing WC and BMI (p < 0.001). Based on the results of logistic regression analysis, NAFLD was found to increase the risk of RE with statistical significance. Even after adjusting for metabolic syndrome and other related factors, NAFLD remained an independent influencing factor for the risk of RE (OR = 2.029; 95% CI 1.459-2.821, p < 0.001).
CONCLUSIONS
The prevalence of NAFLD was significantly higher in patients with RE compared to those without RE. These results indicate that NAFLD has a potential as an independent risk factor for RE, even in non-obese individuals.
