Evaluating the Dietary Intake of Children With Esophageal Atresia: A Prospective, Controlled, Observational Study

Objectives: Children with esophageal atresia (EA) often have feeding difficulties and dysphagia, which may compromise their nutritional status. This study aimed to compare dietary intake between children with EA and matched healthy controls (HC) and to investigate the relationship between dietary factors, growth, dysphagia, and feeding difficulties in the EA cohort. Methods: This cross-sectional cohort study recruited children with EA and HC aged 2-17 years from a tertiary pediatric hospital in Australia. Growth parameters were measured. Dietary intake was assessed using the validated Australian Child and Adolescent Eating Survey. Dysphagia and feeding difficulties were assessed using objective questionnaires. Results: Twenty-one children with EA were matched for age and sex with 21 HC. Compared to HC, children with EA had lower mean z scores for height-for-age, but mean weight-for-age and body mass index-for-age z scores were similar. Energy intake was similar between the groups. The diet of children with EA consisted of a higher proportion of fats and lower proportion of carbohydrates compared to matched HC. Dysphagia severity in children with EA positively correlated with proportion of energy from fats and saturated fats. Conclusions: Children with EA have similar energy intake and growth parameters to HC, but their diet consists of a higher proportion of fats and lower proportion of carbohydrates compared to HC. Targeted dietary interventions and parental education are necessary.
