Association between body mass index and liver disorders: an epidemiological study. Meier, C. R., Krähenbühl, S., Schlienger, R. G., & Jick, H. Journal of Hepatology, 37(6):741--747, December, 2002. abstract bibtex BACKGROUND/AIMS: Cross-sectional studies showed an association between obesity and liver disorders. Information on incidence rates from epidemiological studies is scarce. METHODS: To explore the association between body mass index (BMI) and incident liver disorders, we conducted a follow-up study with a nested case-control analysis using the UK-based General Practice Research Database. The study population encompassed normal weight (BMI \textless25 kg/m(2)), pre-obese (BMI 25-29.9 kg/m(2)) or obese (BMI \textgreater or =30 kg/m(2)) subjects aged 20-79 years, matched on age, sex and general practice attended. RESULTS: Within the study population of 207,630 subjects, we identified 2718 cases of newly diagnosed liver disorder, of whom 1524 (56.1%) had known predisposing conditions. The incidence rates were 2.48 (95% CI 2.31-2.66)/1000 person-years (py) in normal weight, 2.91 (95% CI 2.72-3.11)/1000 py in pre-obese, and 3.83 (95% CI 3.62-4.07)/1000 py in obese subjects. In the nested case-control analysis, the adjusted odds ratio (OR) for obese, as compared to normal weight subjects, was 1.2 (95% CI 1.1-1.4). The OR for idiopathic cases (without known risk factors for liver disorders) was 1.3 (95% CI 1.1-1.6). CONCLUSIONS: The study indicates that obesity is associated with a modest increase in the incidence of newly diagnosed liver disorder.

RESULTS: Within the study population of 207,630 subjects, we identified 2718 cases of newly diagnosed liver disorder, of whom 1524 (56.1\%) had known predisposing conditions. The incidence rates were 2.48 (95\% CI 2.31-2.66)/1000 person-years (py) in normal weight, 2.91 (95\% CI 2.72-3.11)/1000 py in pre-obese, and 3.83 (95\% CI 3.62-4.07)/1000 py in obese subjects.
