| Outline of Final Research Achievements |
We developed the first parent-reported screening questionnaire for ARFID and used it to conduct the to date largest screening studies of ARFID in children up to 7 years. We screened ~3,700 Japanese children aged 4-7 years and 670 Swedish children aged 2-4 years. The prevalence of potential ARFID was 4.6% among the Swedish children and 1.3% among the slightly older Japanese children. Our data support strongly that the questionnaire is a good measure for ARFID. Children with significant neurodevelopmental problems before age 3 had a three times increased risk of later ARFID. Our results also suggested that early neurodevelopmental problems might aid in the early detection of ARFID as they were better predictors than early feeding problems. Based on our results we have improved the questionnaire. It is currently being used in several epidemiological and clinical studies and may be used as a routine screening tool in child health care to enhance the early detection of ARFID.

| Academic Significance and Societal Importance of the Research Achievements |
Our results show that ARFID is not rare among children. We provide an effective questionnaire which may be used as a routine screening tool in child health care to enhance the early detection of ARFID. Screening for early neurodevelopmental problems might additionally aid in detecting ARFID.
