Three-day dietary records obtained from female nutrition students between the years of 1986 and 1991 were examined for secular trends in nutrient intake.
Students kept diet records for two weekdays and one weekend day as part of a course assignment in an introductory nutrition course.
They hand-calculated their mean intakes of energy, macronutrients, calcium, iron, vitamin A, thiamin, riboflavin, niacin, folate, and vitamin C. The students' data were checked for errors, and entered into a data file.
Oneway analysis of variance and correlation analysis were used to detect secular trends in intake.
Over the six years of the study, no changes in energy intake were observed.
