Effects of a nutrition curriculum on selected T.M.R. students

The purpose of this study was to determine the effectiveness of a nutrition education curriculum on: 1) the level of knowledge held by the trainable mentally retarded about nutrition, 2) modification of food selection practices among the study population, and 3) weight loss among participating students. The pretest-posttest control group design was employed to determine, the extent to which, if any, changes in levels of knowledge and weight occurred. The one-group pretest-posttest design was employed to determine observations of behavioral change. The Dairy Council of California "Balanced Meals Posttest" for Grade 2 was utilized as the pretest-posttest instrument for nutrition knowledge. An observation schedule was designed in order to assess any behavioral change(s) in relation to food selections. Pre and post weights were determined by weighing the students on a balance scale. Data obtained from the pre and posttests was subjected to t-Test ratios. Charts obtained from pre and post behavior observations were collected and tabulated to develop a contingency table.
