A three-day nutrition education program on calcium nutriture for female adoles cents ages 14-16 was presented at a midwestern high school. The purpose of the program was to increase the adolescents' knowledge of calcium balance and its importance, thus prompting healthy food and lifestyle habits. The study was conducted using a pretest, posttest, and post-posttest one month later. Each testing period consisted of a nutrition examination, lifestyle questionnaire, and 24-hour diet recall. Data were analyzed by a two-way ANOVA with repeated mea sures. Female adolescents were randomly assigned to an experimental (n = 29) or a no-treatment control group (n = 20). The findings were: (a) the experimental group's nutrition knowledge scores increased significantly following the program and remained significantly higher 30 days later; (b) calcium and vitamin D intakes increased between the pretest and posttest by 27% and 30%, respectively, in the control group and by 24% and 51%, respectively, in the experimental group; and (c) compared to the control group, the mean intakes for calcium, vitamin D, and phosphorus in the experimental group were closer to the RDA for those nutrients, and the calcium:phosphorus ratio was closer to the recommended ratio of 1:1 at the posttest period and at the post-posttest period.
