Special Health Care Needs in Internationally Adopted Children: Prevalence of Chronic Conditions and Interesting Origin-correlated Risk Factors

Introduction: The Federal Maternal and Child Health Bureau defines Children with special health care needs (CSHCN) as those who have, or are at increased risk for, chronic physical, developmental, behavioral, or emotional conditions, and require health and related services beyond what is generally required by other children. More than half of the entire Italian internationally adopted children (IAC) population has special needs. This monocentric retrospective study aims to describe the demographic features and prevalence of several chronic conditions in a large cohort of IAC. Methods: Between 1 January 2009 and 31 October 2023, we consecutively enrolled all IAC referred to Anna Meyer Children's University Hospital, in Florence. This process followed a standardized operative protocol developed internationally. Then, univariate logistic regression analyses were performed. Results: Among 2694 IAC, 315 children (11.89%) were found to be affected by a chronic condition. Asia appears to have 101/561 (18.00%) prevalence of diseases in the total number of IAC from this region of origin, followed by Eastern Europe with 135/1030 (13.11%), Latin America 63/598 (10.54%) and Africa 16/435 (3.68%). The countries of origin with higher prevalence of chronic conditions were China (57.75%), India (15.89%), Russia (15.44%), and Ukraine (13.79%). Children adopted from China and India have a high prevalence of malformations (p = 0.016), while children adopted from Russia accounted for 69.77% of the total fetal alcohol syndrome affected in our cohort. Mental and behavioral disorders appear significantly more prevalent in children from Latin America (p = 0.015), whereas endocrinological disorders predominate in children from Africa (p = 0.014). High rates of precocious puberty were recorded in Asia (p = 0.018) and Africa (p = 0.001) in comparison with the other regions of origin. Conclusion: A revision of the current definition of special needs for adoptive purposes is recommended. Italian screening of the adopted child could be tailored considering the country of origin, and the study of mental health should definitively become part of it.
