Relationship between the consumption of wholegrain and nonalcoholic fatty liver disease: The TCLSIH cohort study
Clinical nutrition (Edinburgh, Scotland)(2022)
摘要
Background & aims: Wholegrain contributes a range of beneficial nutrients and is considered to play a role in the prevention of chronic diseases, but evidence of their influence on nonalcoholic fatty liver disease (NAFLD) is limited. We conducted this study to investigate the prospective association between daily wholegrain consumption and NAFLD in the general population. Methods: This prospective cohort study included a total of 14,968 (42.2% men) inhabitants living in Tianjin, China. Participants without a history of CVD, cancer, alcoholic fatty liver disease, other liver diseases, or NAFLD were followed up for 1-6 years with a median follow-up duration of 4.2 years. Wholegrain consumption was assessed using a validated self-administered food frequency questionnaire. NAFLD was diagnosed with the results of liver ultrasonography without significant alcohol consumption and other causes of liver disease. Cox proportional hazards regression models were used to estimate the association between wholegrain consumption and NAFLD. Results: A total of 3505 (2171 men) first incident cases of NAFLD occurred during 53,303 person-years of follow-up (median follow-up of 4.2 years). After adjusting for several potential confounders and setting "almost never" as the control group, the multivariable hazard ratios (95% confidence intervals) of the NAFLD were 0.82 (0.73, 0.92) when they consuming <1 time/week, 0.78 (0.69, 0.88) when they consuming 2-6 time/week and 0.77 (0.66, 0.90) when they consuming >1 time/day (p for trend <0.001). Conclusion: The results from our prospective study demonstrated that the higher consumption of wholegrain is associated with a decreased risk of NAFLD in Chinese adults.
