Background
Lifestyle modification is currently the only treatment for nonalcoholic fatty liver disease (NAFLD). The most effective way to motivate behavior change in this population is not well understood.
Aims
The aims of this study were to characterize the association between patient disease knowledge, attitudes, and behaviors and to determine the impact of an educational intervention.
Methods
Adults with NAFLD had the following assessed before and after an educational intervention: (1) disease knowledge; (2) health-related quality of life (HRQOL); (3) physical activity; (4) diet; (5) stages of change; and (6) clinical variables.
Results
Median age of the cohort (N = 248) was 53.5, 46% were male, 85% were white, and median body mass index was 33.9. Forty-eight percentage had nonalcoholic steatohepatitis, and 28% had cirrhosis. The median correct knowledge score was 73.6%, median Chronic Liver Disease Questionnaire-NAFLD was 5.2/7, and diet score was 7/16 (higher indicating unhealthy diets). The cohort was sedentary at baseline, with 46% and 60% in active phases of change for nutrition and physical activity, respectively. Fifty-six (22%) had all three high-risk behaviors (sedentary, poor diet scores, low stage of change), which was independently associated with depression. The educational intervention improved diet scores, HRQOL, stages of change, and weight.
Conclusions
Despite good disease knowledge, NAFLD participants were sedentary and 1/4 had high-risk lifestyle behaviors. An educational intervention had positive impacts on clinical outcomes, though effect size was small. Pairing educational interventions with targeted interventions to motivate behavior change can improve care for patients with NAFLD.
