Generalized linear regression with a gamma error distribution and a log-link function. Level of Physical activity is defined as a continuous variable (1 = inactive, 2 = moderate, 3 = Ideal); Model 1 adjusted for Physical activity, age, sex, current smoker, DM, hypertension, hyperlipidemia and obesity; Model 2 adjusted for all variables in model 1 + history of CVD and history of cancer. NAFLD: Nonalcoholic fatty liver disease.
