A CDC report found that millions of children and teenagers are not receiving recommended preventive health services. Data collected before the ACA showed low rates of immunizations, dental care, developmental screenings, and counseling for issues like tobacco use and reproductive health. Only 21.1% of young children received comprehensive developmental screening, and many children lacked basic services like vision and hearing tests. The report indicates certain groups face even lower access, and calls for increased preventive care to promote long-term health.
