Fig. 1a. Mean Calcium Consumption (mg) and 95% Confidence Intervals for Adolescents 12–15 y, 1971–1998.

SOURCE: Adapted from data in Third Report on Nutrition Monitoring in the United States, Table A-6v [21]. Original data sources were HHS, First National Health and Nutrition Examination Survey. 1971–74; USDA, Nationwide Food Consumption Survey, 1977–78; HHS, Second National Health and Nutrition Examination Survey, 1976–80; USDA, Continuing Survey of Food Intakes by Individuals, 1985–86; HHS, Third National Health and Nutrition Examination Survey, 1988–91; USDA, Continuing Survey of Food Intakes by Individuals, 1989–91. Means and confidence for CSFII 1994–96, 1998 were calculated by the authors.

NOTES: The data for CSFII 1985–86 for this age range were missing in the source table. The surveys in the figure used different methods to assess calcium consumption, so caution should be used in making comparisons. However, each was designed to provide a nationally representative estimate of calcium consumption for the time period in which it was conducted.
