RESUMO
OBJECTIVE: To assess the prevalence of pediatric feeding disorder (PFD) in US children. STUDY DESIGN: We conducted a retrospective cohort study of Medicaid Databases from Arizona (2009-2017) and Wisconsin (2005-2014) (public insurance databases) and The Truven Health Analytics MarketScan Commercial Claims and Encounters Database (2009-2015) (a nationwide private insurance database). Diagnoses and procedures were identified from inpatient and outpatient claims using the International Classification of Diseases (ICD)-9 and ICD-10 diagnostic codes and ICD and Current Procedural Terminology-4 procedure codes. Children with PFD were identified by presence of 1 or more PFD diagnosis and absence of any eating disorder diagnoses within a calendar year. RESULTS: We identified 126 002 and 367 256 children 5 years of age or younger with PFD with public and private insurance, respectively. Over a 5-year period (2009-2014) the prevalences of PFD in children with public insurance in Arizona and Wisconsin were 32.91 (95% CI, 32.61-33.20) and 34.73 (95% CI, 34.37-35.09) children per 1000 child-years, respectively. Similarly, the prevalence of PFD in private insurance carriers was 21.07 (95% CI, 21.00-21.14) children per 1000 child-years. The prevalence trends showed a significant linear increase in children within both insurance cohorts. In 2014, the annual prevalence of PFD was 1 in 23, 1 in 24, and 1 in 37 in children under 5 years in the publicly insured cohorts in Wisconsin, Arizona, and the privately insured cohort, respectively. CONCLUSIONS: The prevalence of feeding disorders in the US rivals that of commonly diagnosed conditions such as eating disorders and autism.
