Effect of Fructose Reduction on Non-alcoholic Fatty Liver Disease (NAFLD) and Metabolic Syndrome in Overweight Children

February 28, 2011 updated by: University of Hohenheim

Investigation on the Preventive Effect of Reduced Fructose Consumption on the Development of Non-alcoholic Fatty Liver Disease in Children in a Long Term Study

The aim of the present study is to find out if a dietary intervention mainly focusing on fructose reduction has a preventive effect on the development and progression of NAFLD and the metabolic syndrome in overweight children.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In the intervention study a total of 100 overweight and 50 normal weight children, aged 5-8 years have to be included. At the beginning, two 24-h dietary recalls are performed to assess nutritional intake and fructose consumption. Anthropometric parameters (body weight and height) are measured to calculate BMI and BMI-SDS of the children. Physical activity during leisure time as well as socio-demographic status and "family background" are assessed using different questionnaires. An ultrasound examination of the liver is performed in all participants for detection of signs of fatty liver. From each child included in the study a fasting blood sample is taken to determine the following blood parameters: ALT, AST, γ-GT, uric acid, blood lipids (TG, HDL, LDL, Total cholesterol), blood alcohol, PAI-1 and endotoxin concentration. A part of the blood sample is used for DNA-analysis. In all children systolic (SBP) and diastolic (DBP) blood pressure are also measured. An oral glucose tolerance test (OGTT) is performed after an overnight fast of 12 h (glucose concentration: 1.75 g/kg body weight, maximum 75g). Simultaneously a glucose hydrogen breath test is performed to assess small intestinal bacterial overgrowth (SIBO). After the check-ups at the beginning of the study, children are divided into two study groups: the intervention group and the control group. Based on the daily fructose intake assessed at the beginning of the study, children participating in the intervention group are advised to reduce their daily fructose intake by 50%. In the first study year, every three months and in the second study year, every six months, nutritional counseling is repeated in small groups in which parents and children are separately trained. If families participating in the control group wish, they receive a dietary counseling based on the references of the "DGE" at the beginning of the study. After the first and the second study year the examinations are repeated in all participants (ultrasound examination only after the second study year).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

5 years to 8 years (Child)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study
