Hepatic steatosis is associated with lower levels of physical activity measured via accelerometry.

ABSTRACT:

Objective

Prior studies on the association of physical activity (PA) and nonalcoholic fatty liver disease are limited by reliance on subjective measures of PA. We examined the association between objectively measured PA and hepatic steatosis defined by computed tomography (CT).

Methods

We conducted a cross-sectional study of 1,060 Framingham Heart Study participants who participated in the Multidetector CT 2 substudy and who underwent assessment of PA via accelerometry. Hepatic steatosis was estimated by liver attenuation, as measured by CT. We explored the relationship between liver attenuation and PA using multivariable regression models.

Results

In multivariable-adjusted models, we observed an inverse association between PA and liver attenuation. Each 30 minutes/da
