The health practices of school nurses affect our role as advocates and educators to promote the health of youth. This study describes the health practices of a convenience sample of 388 school nurses who attended the business meeting at an annual school nurse conference. A self-administered, 40-item questionnaire identified health practices of school nurses in the following areas: (a) health promoting behaviors, (b) exercise, (c) nutrition, (d) relaxation and well-being, (e) safety, and (f) substance use. The subjects most often avoided tobacco and wore seatbelts. The majority did not maintain their weight or exercise consistently. Statistical relationships were explored among the subscales and background items. These data document the need to design strategies to narrow the gap between actual school nurse health practices and the important health messages being delivered in our schools. (Contains 3 tables.)
