Theory of planned behavior is cost-effective strategy in nonalcoholic fatty liver disease

Theory of planned behavior (TPB), an idea that links beliefs to behavior, is more effective and cost-effective in changing the nutritional behavior and physical activity of patients with nonalcoholic fatty liver disease (NAFLD), according to a study.

The randomized controlled clinical trial included 87 overweight or obese patients with NAFLD randomized to intervention (n = 42) consisting of 8 training sessions based on TPB or control (n = 45) consisting of nutritional and physical activity recommendations from their internal specialist and nutritionist.

Significant differences in increased mean scores of TPB constructs, decreased liver enzymes, and decreased degree of NAFLD ultrasound were demonstrated between the groups after undergoing the respective interventions.

Those in the intervention group also experienced more activity and healthy diet compared with the control group.
