Characteristics and Outcomes of Failure to Thrive in Pediatric Patients Referred to the King Abdulaziz Medical City Pediatric Clinic

Background: Failure to thrive (FTT) in pediatric populations is a diagnostic challenge with implications for growth and development. Despite its prevalence, detailed epidemiological data, especially concerning organic versus non -organic etiologies, are sparse. This study examines the prevalence, characteristics, and outcomes of organic and non -organic FTT in a pediatric outpatient setting at King Abdulaziz Medical City, Jeddah. Methods: This retrospective chart review included pediatric patients aged three months to 14 years diagnosed with FTT at KAMC from 2016 to 2023. FTT was defined by weights below the 3rd percentile or a decline across two major growth percentiles. Patients were stratified into organic and non -organic FTT groups based on predefined criteria. Prevalence rates, clinical characteristics, and outcomes were compared to draw distinctions between the two categories. Results: Out of 349 evaluated patients, organic FTT was present in 160 patients (45.8%), with gastrointestinal conditions and endocrine disorders being the most common etiologies. Non -organic FTT, accounting for 189 (54.2%) of cases, was primarily associated with inadequate nutritional intake and behavioral factors. Notably, the non -organic FTT group exhibited a significantly higher rate of condition resolution (45.0%) compared to their organic counterparts (32.5%). Furthermore, significant laboratory parameter differences were noted, indicating a higher white blood cell count in organic cases, among other findings. Conclusions: Non -organic FTT was more prevalent and demonstrated higher resolution rates, suggesting better outcomes with timely intervention and appropriate care strategies. The study advocates for increased educational efforts for caregivers and healthcare providers and calls for further research to explore effective management protocols for FTT.
