Study summary

The efficacy of PUFAs (as nutritional supplement) in/for pre-school children with ADHS symptoms will be evaluated in a randomised controlled doubleblind trail with children aged 3-6 years.

Read the detailed description

The study aims at the reduction of hyperactivity, inattention and impulsivity in pre-school children aged 3-6 years, visiting a preschool, and the prevention of clinical ADHD symptoms. The 3-6 years old children will be identified by a combined parent and teacher rating ADHD-symptoms questionnaire (FBB-ADHS-V). Children with ADHD symptoms >90th percentile will participate in a following diagnostic process. The children (n = 150) will be randomised doubleblind to a control group (taking every day four capsules Equazen eye q, containing 400 mg fish oil and 100mg evening primrose oil - EPA (372mg), DHA (116mg), GLA (40mg) and vitamin E (7.2 mg) ) or placebo group. The study is divided into two phases with four months each. After unblinding after the first phase pre-school children taking placebo receive Omega-3/Omega-6 Fatty Acids. Children (n = 75) taking verum during first four months will be randomised doubleblind to verum or placebo. In this way the progress of the behaviour symptoms will be evaluated after a significant period of time (eigth months). Clinical examination (questionnaires, intelligence test, medical examination) and evaluation of ADHD symptoms through parents and teachers with several questionnaires will be used before beginning, after four months and after eight months. In addition the pre-school children will be taken a blood sample (finger prick test) to measure the omega-3/omega-6 fatty acids levels. Additionally regular phone calls will be implemented. Medical examinations and meetings will taken place if required. If symptoms increase, children will be treated medical and/ or psychotherapeutically.

What researchers measure

Primary outcomes

  1. Change in Symptom Checklist for pre-school children with ADHD symptoms (FBB-ADHS-V) total score rated by parents and teachers

    The FBB-ADHS-V Questionnaire is a developed parent and teacher rating scale which assesses several factors of hyperactivity, impulsivity and inattention problems in pre-school or at home.

    Time frame: Change from pre- assessment to post assessment four months after treatment begin and to post assessment eight months after treatment begin

Secondary outcomes

  1. Change in ODD symptoms -parent/ teacher rated (FBB-ADHD-V)

    Time frame: Change from pre- assessment to post assessment four months after treatment begin and to post assessment eight months after treatment begin

  2. Change in Child Behavior Checklist (CBCL) and Teacher Report Form (TRF)

    The CBCL and the TRF are well evaluated rating scales for the assessement of a broad spectrum of child behavioral and emotional problems as perceived by parents and teachers respectively

    Time frame: Change from pre- assessment to post assessment four months after treatment begin.

  3. Diagnostic checklist for ADHD (DCL-ADHS) and diagnostic checklist for odd (DCL-SSV)

    The DCL-ADHD and the DCL-ODD are external assessment questionnaires. Parents were asked 18 questions to hyperactivity, impulsivity and inattention by the rater or to symptom criteria for ODD.

    Time frame: Change from pre- assessment to post assessment four months after treatment begin and to post assessment eight months after treatment begin

  4. Change in intelligence: Sequential & Simultaneous Processing, Achievement (K-ABC)

    The Kaufman Assessment Battery for Children (K-ABC) is a standardized test that assesses intelligence and achievement in children aged 2;6 to 12;6 years. It is comprised of four global test scores that include: sequential processing scales, simultaneous processing scales, achievement scales and mental processing composite. There is an additional nonverbal scale.

    Time frame: Change from pre- assessment to post assessment four months after treatment begin.

Other outcomes

  1. finger prick test to measure the PUFA blood concentration

    It will taken a blood sample (finger prick test) to measure the omega-3/omega-6 fatty acids levels.

    Time frame: Change from pre- assessment to post assessment four months after treatment begin
