Project LEAN--lessons learned from a national social marketing campaign.

The Henry J. Kaiser Family Foundation initiated a social marketing campaign in 1987 to reduce the nation's risk for heart disease and some cancers. Consensus on recommendations for dietary change have stimulated the development of a variety of social marketing campaigns to promote behavior change. Project LEAN (Low-Fat Eating for America Now) is a national campaign whose goal is to reduce dietary fat consumption to 30 percent of total calories through public service advertising, publicity, and point-of-purchase programs in restaurants, supermarkets, and school and worksite cafeterias. The public service advertising reached 50 percent of the television viewing audience and the print publicity, more than 35 million readers. The toll-free hotline received more than 300,000 calls. Thirty-four organizations joined the foundation in partnership and raised $350,000 for collaborative activities. Thirteen States implemented local campaigns. Lessons have been learned about the use of the media, market segmentation, effective spokespersons, and successful partnerships. These lessons will be valuable to others planning social marketing campaigns on nutrition and other preventive behaviors.
