Self-concept as a factor in the quality of diets of adolescent girls.

The effect of self-concept on the quality of diets of adolescent girls was investigated. Scores for self-concept as measured by the Tennessee Self Concept Scale (TSCS) and fat area values were obtained from 160 15-year-old girls. Twenty-four-hour dietary recall interviews were conducted with a random subsample of 40 girls. Mean dietary adequacy ratios (MARs) were calculated to assess dietary quality. Girls in this study had larger arm fat areas than did their national counterparts. Mean intakes of energy and nine nutrients met or exceeded their respective RDAs except for vitamin A, calcium, and iron. MAR values were correlated positively with Self-Satisfaction scores and negatively with carbonated beverages, candy, and baked desserts. Fat area values were correlated negatively with Physical Self scores. Significant predictors of MAR values below 80% were Total Conflict, Moral-Ethical Self, Family Self, Identity, and Physical Self scores.
