Medical examination of school entrants: later school problems and absenteeism of attenders and non-attenders.

Children who were scheduled for medical examination before entering school were followed in school one or two years later. Non-attenders had a two-fold risk of repeating grades, special class placement, referral for speech/language problems, teacher-reported learning or behavior problems, failure of vision or hearing screening, and transfer between schools. Absenteeism was also significantly more common. Children not brought in for preventive health care are at greater risk than others for difficulties in school.
