Shim, Kim, Ji, Sohn, Hwang, and Chung: The Effects of a Nutrition and Body Shape Education Program as Part of Health Promoting Projects in an Elementary School

Abstract

The purpose of this study was to evaluate the effects of a nutrition education program as part of health promoting projects in an elementary school. A total of 168 students in the 4th grade were enrolled in the program for 6 months. A self-administered questionnaire was developed to assess nutrition knowledge and dietary habit. Nutrient intakes and body shape perceptions were measured using 24-hour recall method and self-ratings of body shape figures, respectively. The education program was conducted in various ways, focused on healthy dietary behavior, nutrients' roles and sources, and proper body shape perceptions, etc. After the education program, nutrition knowledge and dietary habit were significantly improved. Dietary habit scores were significantly and positively related to nutrition knowledge levels. Body shape perceptions were significantly and properly changed after the program. Dissatisfaction with perceived current body shape and discrepancy between shapes desired and considered healthy were significantly decreased. But girls still indicated a desire to be leaner than shapes which were perceived current and considered healthy. Nutrient intakes were partly improved by the program, but some nutrients, such as calcium, folate, zinc, sodium and niacin, were still remained deficient or excessive. These findings indicate that enhancement of nutrition knowledge is extended to the improvement of dietary habit. In addition, establishment of proper body shape perception is closely related to healthy dietary habits and is required to good nutrition and health.

Figures and Tables

Fig. 1
Body mass and Rohrer's indices by perceived current body shape. 1) Body mass index = body weight (kg)/height (m)2, 2) Rohrer's index = {body weight (g)/height (cm)3} × 100. Analysis of variance (Student-Newman-Keuls test) was performed to test the difference between means of each body shape groups. Bars with a different letter or letters are significantly different at p < 0.05.
