[including the WHO Working Group on Infant Growth, of which Kathryn Dewey is a member] Growth of breast-fed infants deviates from current reference data: a pooled analysis of US, Canadian and European datasets. Pediatrics 1995;96(3):495-503, the full report of the WHO Working Group on Infant Growth. document WHO/NUT/94.8, 83 pages, including pooled data presented in growth chart form, is available through Distribution and Sales, World Health Organization, 1211 Geneva 27, Switzerland, fax (41-22) 791-4857. The implications of adopting an international growth chart using reference data based on breast-fed infants are discussed in: An evaluation of infant growth: the use and interpretation of anthropometry in infants. Bulletin of the World Health Organization 1995, 73(2):165-174.
