  1. Fulltext. Portion-size estimation training in second-and third-grade American Indian children.

    Article - En anglais


    Training in portion-size estimation is known to improve the accuracy of dietary self-reporting in adults, but there is no comparable evidence for children.

    To obtain this information, we studied 110 second-and third-grade American Indian schoolchildren (34 control subjects were not trained), testing the hypotheses that a 45-min portion-size estimation training session would reduce children's food quantity estimation error, and that the improvement would be dependent on food type, measurement type, or both.

    Training was a hands-on, 4-step estimation and measurement skill-building process.

    Mixed linear models (using logarithmic-transformed data) were used to evaluate within-and between-group differences from pre-to posttest.

    Test scores were calculated as percentage estimation errors by difference and absolute value methods.

    Mean within-group estimation error decreased significantly (P<0.05) from pre-to posttest for 7 of 12 foods (trained group) by both calculation methods, plus 3 additional foods by the difference method and one additional food by the absolute value method.

    Significant (P<0.05) between-group differences occurred for 3 foods, reflecting a greater decrease in estimation error for the trained group.

    Improvement was greatest for solid foods estimated by dimensions (P>0.05) or in cups (P<0.05), for liquids estimated by volume or by label reading (P<0.001), and for one amorphous food estimated in cups (P<0.01). (...)
