This study assessed the associations between lifestyle factors and the progression of chronic liver disease. It found that high-risk lifestyle factors played a key role in all stages of disease transition, from healthy to chronic liver disease, subsequently to cardiometabolic disease, and then to death, with varying magnitudes of associations.
Background Lifestyle factors are associated with chronic liver disease (CLD) and death after CLD diagnosis. How-ever, their associations with pathways of CLD progression have been unclear, particularly transition to cardiometabolic disease (CMD), a major comorbid condition with CLD. We assessed the associations of lifestyle factors with CLD progression. Methods The study population involved 486,828 participants of the prospective China Kadoorie Biobank (CKB) aged 30-79 years without a history of cardiovascular disease, diabetes, CLD, or cancer at baseline. Liver-cardiometa-bolic comorbidity (LCC) was defined as developing CMD subsequently after first CLD (FCLD) in an individual. A multi-state model was used to estimate the associations of high-risk lifestyle factors (smoking, alcohol, physical inactivity, and central adiposity) with CLD progression from healthy to FCLD, subsequently to LCC, and further to death. Findings During a median follow-up of 11 years, 5046 participants developed FCLD, 519 developed LCC, and 157 died afterwards. There were positive associations between the number of high-risk lifestyle factors and risks of all transitions. The hazard ratios (95% CIs) per 1-factor increase were 1.30 (1.25-1.35) for transitions from baseline to FCLD, 1.21 (1.09-1.34) for FCLD to LCC, 1.20 (1.17-1.23) for baseline to death, 1.15 (1.09-1.22) for FCLD to death, and 1.17 (1.06-1.31) for LCC to death. For CLD subtypes, lifestyle factors showed different associations with disease -specific transitions even within the same transition stage. Interpretation High-risk lifestyle factors played a key role in all disease transition stages from healthy to FCLD, sub-sequently to LCC, and then to death, with different magnitude of associations.
