| This study examined differences in total calorie and % calories from fat consumed between three different methods of measurement (Record 1; 24-hour recall, record 2; 24-hour weighed food record and 48-hour weighed home food record, and record 3; 24-hour recall and 48-hour home food record). A total of 81 participants, ages 9-12, were used in the analysis. A multivariate approach to repeated measures ANOVA was used to test for differences in total caloric intake and % calories from fat among the three methods of measurement. A significant difference in the mean caloric intake of study participants was found between record 1 and record 3 (p < .0005), and record 2 and record 3 (P < .0005). A Bonferroni correction was used to test for differences in variability in total caloric intake and % calories from fat among the three methods of measurement. A statistically significant difference was found in variability of caloric intake between record 1 and 2, and between record 1 and 3 (p < .0167). A statistically significant difference was found in variability of % calories from fat between record 1 and record 2, and record 2 and 3 (p < .0167). In conclusion, it was found that record 2 had the least variability and was therefore the best way to collect dietary intake records of adolescents. |
