Families with children have become the fastest growing segment of the homeless population; they accounted for 34% of the homeless in 1990 ( 1. US Conference of Mayors A Status Report on Hunger and Homelessness in America's Cities: 1990. A 30-City Survey. US Conference of Mayors, Washington, DC1990 Google Scholar ). The Institute of Medicine ( 2. Institute of Medicine Homelessness, Health and Human Needs. National Academy Press, Washington, DC1988 Google Scholar ) estimates that there are at least 100,000 homeless children every night, and approximately half of these children are younger than 6 years of age ( 3. US General Accounting Office Children and Youths: About 68,000 Homeless and 186,000 in Shared Housing at Any Given Time. in: 10th ed. GAO publication. PEMD-89-14. US General Accounting Office, Washington, DC1989 Google Scholar ). Despite recent studies examining the health of homeless children ( 4. Alperstein G Rappaport C Flanigan JM Health problems of homeless children in New York City. Am J Public Health. 1988; 78: 1232-1237 Google Scholar , 5. Miller DS Lin EHB Children in sheltered homeless families: reported health status and use of health services. Pediatrics. 1988; 81: 668-673 Google Scholar ), little research has been done on homeless children's dietary intake or growth status ( 6. Fierman AH Dreyer BP Quinn L Shulman S Courtlandt CD Guzzo R Growth delay in homeless children. Pediatrics. 1991; 88: 918-925 Google Scholar , 7.

This article provides information about the diets and physical growth of preschool boys and girls living in shelters for the homeless in Baltimore, Md, and suggests ways for dietitians to work with homeless parents and shelter staff to improve diets available to homeless families.
