A new model for the breastfeeding intervention program was implemented in a Korean community health center and the effectiveness of the program was evaluated. Thirty health care personnel from 29 smaller community health centers and 23 breastfeeding helpers were trained in four workshops. They then gave information on breastfeeding to pregnant and lactating women, living in each community in groups or individually. The breastfeeding rate after intervention has significantly increased at 1 week and 9 months of age. These results indicate that the community-based breastfeeding intervention program by training both the health care professionals and peer helpers is effective in promoting breastfeeding.
