Abstract

Introduction Alcohol and fat are major causes of chronic liver disease (CLD), however their relative influences are not well understood. We aimed to determine liver-related morbidity and mortality attributable to fat and alcohol by stratifying a cohort of 202,638 women according to BMI and alcohol intake.

Methods 107,742 women participating in the UK Collaborative Trial of Ovarian Cancer Screening where self-reported height, weight and alcohol intake were available were included. First episode related to cirrhosis (ICD-10 codes K70, K73, K74) either from inpatient Hospital Episode Statistics or death certificate was recorded following trial entry. Participants were stratified by low or high BMI ( < 25 or ≥25 kg/m2), low or high alcohol intake (0–15 or over 15 units/week) and combinations of these parameters.

Results Median age at recruitment was 60 years (50–75). Mean BMI was 26.4 kg/m2. There were 90 events (54 inpatient episodes and 36 deaths). There was no difference in risk of event between the BMI groups, however there was a significant increase in risk in the high alcohol group (Log-Rank < 0.001). Cox proportional hazards regression analysis (covariates age, smoking, BMI and alcohol intake), found that compared to the low BMI/low alcohol group, there was an incremental increase in risk of event in the high BMI/low alcohol, low BMI/high alcohol and high BMI/high alcohol groups respectively. However, only the combination of high BMI and high alcohol reached significance (table and figure).

Abstract OC-006 Table

Conclusion These data indicate that the combination of high BMI and alcohol intake is associated with a synergistically increased risk of CLD. Alcohol may be the more significant contributing factor. Further work will define thresholds for each risk factor that independently and in combination increase CLD risk.
