Impact of Dietary Consumer Behavior on Non-alcoholic Fatty Liver Disease Vary by Socioeconomic Status

Overview

Non-alcoholic fatty liver disease (NAFLD) affects 25% of adults, becoming the most prevalent cause of liver disease in the world. Although socioeconomic factors are known to have an effect on NAFLD, the effects of food spending and dietary consumer behavior on NAFLD are unclear. This study aims to evaluate the impact of food spending and dietary consumer behavior on NAFLD. The study used data from the National Health and Nutrition Examination Survey (NHANES) 2017 to 2018, including FibroScan, diet, and consumer behavior data. Participants (n=3486) were categorized into no NAFLD, NAFLD without advanced fibrosis, and NAFLD with advanced fibrosis based on Fibroscan. High- and low-income groups were distinguished using self-reported family monthly income and poverty index. A multivariable ordered regression model was conducted. The results showed that frequent fast food consumption was associated with more severe NAFLD in high-income(HI) groups, while more frequent home preparation of meals and greater proportion of money spent on groceries protected against NAFLD in HI groups. These findings were not found in low-income(LI) groups. HI groups have better diet quality, particularly in those who prepare meals at home more frequently. These findings indicate that dietary consumer behaviors–such as fast food consumption and home preparation of meals–are independently associated with NAFLD, but this may be affected by economic status. Thus, lifestyle interventions for NAFLD should consider patients’ dietary behavior, such as fast food consumption and home preparation of meals, but should consider diet quality which is likely affected by the individual’s socioeconomic status.
