Recent Developments in Eating Disorders in Children: A Comprehensive Perspective

Recent years have witnessed a concerning rise in early-onset eating disorders (EDs), prompting a re-evaluation of their etiology, diagnosis, and treatment within pediatric populations. This perspective article synthesizes emerging evidence on the multifactorial origins of EDs in children, emphasizing a biopsychosocial framework that integrates genetic, epigenetic, psychological, and environmental factors. While early manifestations often diverge from adolescent or adult profiles—marked by somatic complaints, selective eating, and ritualistic behaviors—the disorders significantly interfere with developmental milestones. The COVID-19 pandemic has further exacerbated vulnerabilities, acting as a catalyst for disordered eating behaviors through increased familial stress, isolation, and disrupted routines. Central to this framework is the role of parental psychopathology and parent–child feeding interactions, which profoundly shape children’s emotional regulation and attachment patterns. Recent studies also underscore genetic susceptibilities—especially variants in the DRD4 and DAT1 genes—and epigenetic modifications that may mediate the transmission of risk across generations. The article reviews evidence from observational and genomic studies, highlighting how altered gene expression linked to early environmental stress contributes to the heterogeneity of EDs. Finally, it evaluates prevention and intervention strategies, including family-based treatments, digital health tools, and school-based programs. These strategies are essential for timely detection, individualized care, and reducing long-term impairment. Overall, the paper advocates for a nuanced understanding of EDs in children—recognizing their complex origins and developmental implications—to inform clinical practice, public health policy, and future research in pediatric mental health.
