Functional roles of today's public health nutritionist.
This study found that functional roles of public health nutritionists in eight southeastern states differed significantly on the basis of education, dietetic registration status, years of experience, and type and level of service. Subjects (n = 992) were mailed a 95-item questionnaire with three parts: demographic, professional practice, and grant-writing experience. Results based on a 59% response rate indicated that most of the 14 functional roles studied were practiced in accordance with guidelines presented in Personnel in Public Health Nutrition for the 1980's. Only two roles, counselor and educator, were performed somewhat inconsistently. Personnel with bachelor's degrees did have more counseling responsibilities than those with more advanced degrees. However, nonregistered dietitians also had more counseling responsibilities than did registered dietitians. Direct care providers had fewer educator responsibilities than did personnel with administration/management job responsibilities. All personnel reported research responsibilities that increased with advanced education, training, years of experience, and type and level of service. We found that beyond-entry-level personnel had more administrative and policy-setting responsibilities, which is consistent with The American Dietetic Association's Role Delineation for Registered Dietitians and Entry-Level Dietetic Technicians (1990). We conclude that, with the exceptions of the counselor and educator roles, public health nutrition practice is consistent with personnel guidelines.
