This study investigated the prevalence of eating disorders, including avoidant/restrictive food intake disorder (ARFID), in adolescents and young adults with cystic fibrosis (CF). The results showed a clinically significant number of participants screened positive for eating disorders. The eating and weight scales of the CF questionnaire were associated with the scores on these surveys. Further research is needed to understand the optimal way to screen and treat eating disorders in individuals with CF.
Introduction There is evidence for increased risk of eating disorders in individuals with diet-treated chronic illnesses, however, data in patients with cystic fibrosis (CF) is less clear. No studies have evaluated avoidant/restrictive food intake disorder (ARFID) in the CF population. We investigated the prevalence of eating disorders, including ARFID, in adolescents and young adults with CF. Methods Patients with CF aged 14-35 years were recruited to complete three validated surveys: (1) Eating Disorder Examination Questionnaire (EDE-Q), (2) Nine-Item Avoidant/Restrictive Food Intake Disorder Scale (NIAS), and (3) Cystic Fibrosis Questionnaire-Revised (CFQ-R). Univariate linear regression analysis identified baseline risk factors associated with these survey scores. Variables with univariate p < 0.20 were considered for inclusion in a multivariable linear regression model. Backwards stepwise linear regression was used to identify the final model. Results A total of 52 patients enrolled. The prevalence of a positive screen on the EDE-Q was 9.6%, and on the NIAS was 13.5%. The CFQ-R eating and weight subscales were associated with scores on the EDE-Q, and CFQ-R eating subscale and being dF508 homozygous were correlated with the NIAS total score. Discussion A clinically significant number of participants screened positive for eating disorders on the EDE-Q and NIAS. Scores on the eating and weight scales of the CFQ-R were associated with the scores on these surveys. Further work is needed to better understand the optimal way to use such tools to screen and treat for eating disorders in individuals with CF.
