Plain English Summary
Background and study aims
There is evidence that family dietary education programmes are effective in children with obesity, but there is little evidence of this in children with non-alcoholic fatty liver disease (a build-up of fat in the liver cells). The aim in this study is to assess the effect of a nutritional counselling programme on hepatic abnormalities associated with non-alcoholic fatty liver disease in obese children.
Who can participate?
Children who are obese and have non-alcoholic fatty liver disease
What does the study involve?
Patients will have a clinical assessment and liver function tests at baseline and after 4 months of intervention. They will attend nutrition counselling sessions with their parents or guardians every 15 days.
What are the possible benefits and risks of participating?
The possible benefits are body-mass index reduction and improvement in the primary alterations in liver function associated with non-alcoholic fatty liver disease in obesity. Risks not provided at time of registration.
Where is the study run from?
Pediatric Hospital of the National Medical Center XXI Century (Mexico)
When is the study starting and how long is it expected to run for?
From October 2008 to December 2012
Who is funding the study?
National Council of Science and Technology (Mexico)
Who is the main contact?
Dr Segundo Moran

Patient information sheet
Non-alcoholic liver dsease
From the start of the study and every 15 days thereafter during 4 months, both children and their parents in small groups had one-hour sessions conducted by a dietitian and a medical doctor. These sessions provided educational material about the importance of adequate food intake, with emphasis on lowering the amount of refined sugar and sugary sodas, reducing the amount of carbohydrates and fat consumed every day, and increasing the amount of fibre.
