The Healthy Mothers, Healthy Babies Coalition is a cooperative venture of 80 national voluntary, health professional, and governmental organizations committed to improving maternal and infant health through education. In the 4 years since its creation, the Coalition has grown in scope and size, established an Executive Secretariat, and begun activities directed at breastfeeding, substance use, injury prevention, genetics, oral health, adolescent pregnancy, and motivation of low-income women. National Coalition educational materials on these subjects are produced by representatives of the national organization members contributing time and their organization's resources. In addition, member organizations sponsor the publication of a quarterly newsletter and other coalition-building materials including an exhibit, slide-tape show, television production kit, and a community organization guide. Combined with State and community enthusiasm for the Healthy Mothers, Healthy Babies concept, technical assistance from national members has led to the formation of coalitions in many States--more than 40 States have designated contacts with the national coalition. The State coalitions have undertaken a variety of campaigns; the achievements in 12 States are outlined. Of high priority during the next year will be support of these developing State coalitions through co-sponsorship of regional conferences. The national Coalition will also continue to recognize innovative programs through annual national achievement awards. The Healthy Mothers, Healthy Babies Coalition is dedicated to continued development and promotion of educational programs for pregnant women, those planning a pregnancy, and their caregivers until 1990, in support of the health Objectives for the nation.
