The department's scope of diagnosis and treatment includes intellectual developmental disability, language developmental disorder, childhood autism, attention deficit hyperactivity disorder, feeding difficulties, malnutrition, non-organic enuresis, sleep disorders, tic disorders, rickets, and others. Patient sources span Shanghai, nationwide, and overseas, with outpatient visits reaching 240,000 in the past three years. The department pioneered the integration of medical and educational intervention models, adhering to a combination of pharmacological treatment and family therapy. Through the establishment of a green channel for medical access, health education, parent training, family therapy, and behavioral interventions, individualized treatment is provided with significant efficacy. A tiered diagnosis and treatment system for child health diseases within the pediatric medical consortium has been established, promoting nationwide initiatives such as "Intervention for Early Glucose Metabolism Abnormalities in Obese Children" and the "Diagnosis and Treatment Management System for Infant Feeding Difficulties," serving as a professional leader. The department leads research on the infant brain and intelligence plan, constructing cohorts for embryonic brain, preterm infant brain, developing brain from 0-6 years, and abnormal developmental brains such as autism, to elucidate the rules of child brain and intelligence development and formulate strategies for brain and intelligence enhancement. Department members have contributed to the writing of multiple professional guidelines to guide clinical and educational practice, including "Principles for Identifying and Managing Common Comorbid Problems in Children with Autism Spectrum Disorder," "Expert Consensus on Early Identification, Screening, and Early Intervention for Children with Autism Spectrum Disorder," "Physical Activity Guidelines for Chinese Children and Adolescents," "Sleep Hygiene Guidelines for Children Aged 0-5 Years," "Infant Feeding Guidelines," "Chinese Guidelines for the Prevention and Treatment of Attention Deficit Hyperactivity Disorder (Second Edition)," "Chinese Expert Consensus on Monosymptomatic Enuresis in Children," and public health policy recommendations for children's sleep. The department has led projects that have received two National Science and Technology Progress Second Prizes, one Ministry of Education Science and Technology Progress First Prize, and one Natural Science Award from the Maternal and Child Health Science and Technology Award. The Department of Developmental and Behavioral Pediatrics (Child Health Care) at Shanghai Children's Medical Center has maintained close exchanges and cooperative relationships with developmental and behavioral pediatrics departments in developed countries in Europe and America, such as Cincinnati Children's Hospital in the United States and Children's Wisconsin in the United States. Each subspecialty lead physician has received medium- or long-term professional training abroad, mastering the latest international developments and technologies in the field, and has played an outstanding role in diagnosing and treating rare and difficult cases.
