Adherence to the dietary approaches to stop hypertension diet and non‐alcoholic fatty liver disease

摘要

Abstract Background and Aims The evidence of the relationship between dietary approaches to stop hypertension (DASH) and non‐alcoholic fatty liver disease (NAFLD) is limited. Thus, we conducted a cohort‐based case‐control study to examine whether adherence to the DASH diet was associated with lower NAFLD risk in China. Methods We included 11?888 participants (2529 incident NAFLD and 9359 non‐NAFLD) from the Kailuan cohort with no history of hepatitis B/C infection and alcohol drinking. DASH score was calculated based on the energy‐adjusted consumption of vegetables, fruits, dairy, beans, grains, meats, fat, sodium and beverage, collected by a validated food frequency questionnaire. We used Logistic regression analysis to determine the NAFLD's risk according to the DASH score. Results Higher DASH score was associated with lower risk of NAFLD. Compared with the lowest quintile of DASH score, the highest DASH quintile had a lower risk of occurring NAFLD, with odds ratio (OR) of 0.82 (95% confidence interval [CI]: 0.70‐0.96) in the multivariate model. Stratified analysis showed that the inverse association was only observed in women (OR?=?0.67, 95% CI: 0.48‐0.94), and participants with overweight/obesity (OR?=?0.79, 95% CI: 0.66‐0.94), fasting blood glucose <6.1?mmol/L (OR?=?0.80, 95%: 0.67‐0.96), low density lipoprotein ≥3.4?mmol/L (OR?=?0.71, 95% CI: 0.53‐0.96), high density lipoprotein ≥1.0?mmol/L (OR?=?0.81, 95% CI: 0.69‐0.96), ALT?
