Objectives Trends between 1977/1978 and 1994/1998 in the prevalence, amounts, and sources of soft drink consumption were examined among youth age 6 to 17 years. Design Dietary intake data were examined from three national surveys: the Nationwide Food Consumption Survey 1977/1978 (n=8,908), and the combined Continuing Survey of Food Intakes by Individuals 1994/1996, and the Supplemental Children's Survey 1998 (n=3,177). Soft drinks were defined as carbonated beverages (all United States Department of Agriculture database codes starting with 924) and included flavored waters and juice drinks. Subjects/Setting A national sample of youth ages 6 to 17 years were interviewed for each of the 3 surveys. Statistical analysis t tests were conducted to examine between-survey changes in soft drink consumption and sources of soft drinks. Results The prevalence of soft drink consumption among youth ages 6 to 17 years increased 48%, from a prevalence of 37% in 1977/1978 to 56% in 1994/1998. Mean intake of soft drinks more than doubled, from 5 fl oz to 12 fl oz per day. Although the home environment remained the largest source of children's soft drink access, an increasing share was obtained from restaurants and fast-food establishments (+53%), vending machines (+48%), and other sources (+37%). Conclusions Away-from-home sources of soft drink are an important factor for dietitians to consider when evaluating the dietary intake and nutritional status of youths.
