Knowledge and opinions of asymptomatic adolescents and their caregivers on celiac disease screening

Objectives: Celiac disease (CD) is an immune enteropathy caused by sensitivity to gluten affecting one per cent of the general population. Most people with CD are asymptomatic and some may be affected from childhood. Despite the latest recommendations of paediatric gastroenterology societies, targeted screening is still uncommon in clinical paediatric settings. A poor understanding of the asymptomatic population's opinions creates obstacles for broader implementation of CD screening. This study aims to fill this gap by reporting on the knowledge and opinions of adolescents and caregivers of children on CD screening. Methods: Adolescents with absence of classical symptoms of CD and caregivers of presumably asymptomatic children were asked about their knowledge and opinions of CD through a self-administered questionnaire. Results: There were 227 respondents including 76 adolescents and 151 caregivers. A minority of respondents (8% of caregivers and 23% of adolescents) were identified as having a CD-associated condition (such as hypothyroidism, type 1 diabetes, Down syndrome, etc.). A majority of caregivers (84%) and half of adolescents (49%) already knew about CD. Half of the respondents (46%) were in favour of screening asymptomatic paediatric populations and this agreement increased to 81.7% when they were confronted with hypothetical risks of 10%. Conclusion: This study reveals an increased willingness to screen when participants were faced with increasing hypothetical risks. This suggests that screening recommendations targeting high-risk populations, such as those of paediatric and non-paediatric gastroenterology societies, may be more widely accepted.
