Obesity has been associated with liver fibrosis, yet guidelines do not emphasize it as an independent risk factor in which to have a high index of suspicion of advanced disease..
..We prospectively recruited patients from a primary care practice with hazardous alcohol use and/or type 2 diabetes and/or obesity. Subjects were invited for a transient #elastography reading. A threshold of ≥8.0 kPa defined an elevated reading consistent with clinically significant liver disease..
..The proportion of patients with an elevated reading was similar among those with obesity (8.9%) to patients with more recognized solitary risk factors (type 2 diabetes 10.8%; hazardous alcohol use 4.8%). Obesity in combination with other risk factors further increased the proportion of patients with an elevated reading. In multivariate logistic regression, increasing body mass index and type 2 diabetes were significantly associated with an elevated reading.
DISCUSSION: Obesity as a single or additive risk factor for chronic liver disease is significant. Future case-finding strategies using a risk factor approach should incorporate obesity within proposed algorithms.
