The extent of the use of services for the new morbidity, that is, children's behavioral, educational, and family-social problems, has not previously been the subject of a community-based prospective study. The demographic characteristics and utilization of school and community health care resources over a two-year period are compared for two groups selected from a random sample (n = 671) of elementary school children. Twentyfour percent (n = 164) were observed to have behavioral, educational, or social-family problems requiring attention or intervention by health or educational personnel. This group was compared to their schoolmates (n = 507) not so identified. Although no overall differences in sex, ethnic background, or family structure were identified, the children with new morbidity problems were more frequently in the lowest socioeconomic group, and had lower reading achievement scores and higher rates of absenteeism. The new morbidity group also had higher rates of utilization of services both at school and at community sites of health care, not only for new morbidity complaints, but for other problems as well. The data suggest that this portion of the school-aged population places a significant demand for health care resources on both community and school sites. The findings support the need for training of physicians in the care and prevention of such problems.
