Children with intellectual disabilities have an increased risk of visual impairment, caused by both ocular and cerebral abnormalities, but this risk has not been quantified. The same applies to preterm children and children with cerebral palsy with a normal intelligence. Many cases probably go unidentified, because participation of these children in preschool vision screening programs is not guaranteed, or because no screening program is available. Although there may be a case for specific screening, there is insufficient scientific evidence supporting such a claim. A "safety net" construction for vision screening is proposed by a Dutch expert working party, based on scientific information and joint professional expertise, to improve identification of both ocular and cerebral visual impairment in at-risk groups. Costs and gains of the model should be scientifically evaluated in a test region.

Air-Displacement-Plethysmography (ADP) by BOD POD is widely used for body fat assessment in children. Although validated in healthy subjects, studies about use in pediatric patients are lacking. We evaluated user experience and usability of ADP measurements with the BOD POD system in healthy children and pediatric and young adult patients. Using the experiences of seven cohort studies, which included healthy children and patients aged 2–22 years, we retrospectively evaluated the user experience with the User Experience Questionnaire (UEQ) (n = 13) and interviews (n = 7). Technical performance was studied using the quality control data collected by the ADP-system. From 2016 to 2022, 1606 measurements were scheduled. BOD POD was mostly rated 'user-friendly', with a generally neutral evaluation on all scales of the UEQ. However, questionable reliability and validity of the results were frequently (86%) reported. We found a high technical failure-rate of the device, predominantly in stability (17%) and accuracy of the measurement (12%), especially in the 'pediatric option' for children aged <6 years. Measurement failure-rate was 38%, mostly due to subject's fear or device failure, especially in young and lean children, and in children with physical and/or intellectual disabilities. We conclude that ADP by BOD POD in children and young adults is non-invasive and user-friendly. However, in specific pediatric populations, BOD POD has several limitations and high (technical) failure-rates, especially in young children with aberrant body composition. We recommend caution when interpreting body composition results of pediatric patients as assessed with BOD POD using the current default settings. [ABSTRACT FROM AUTHOR]
