The relationship between self-rated health status and the overall quality of dietary intake of US adolescents.

The objective of this study was to compare the quality of overall dietary intake of US adolescents by self-rated health status. Using 2 nonconsecutive days of dietary recall data and responses to a single question describing self-rated health status from the Continuing Survey of Food Intakes by Individuals 1994-1996, linear regression analysis was used to detect differences in Healthy Eating Index (HEI) scores by self-rated health status for 1,504 adolescents, ages 11 to 18 years. After adjusting for factors related to both overall dietary quality and self-rated health status, overall HEI scores did not differ by self-reported health status. However, two individual HEI component scores were found to be significantly related to adolescent self-rated health status: the vegetables score (P=0.01) was higher among those with positive self-rated health status, and the total fat score (P=0.01) was higher among those with negative self-rated health status. Self-perception of health status is not related to the overall quality of the adolescent diet; therefore, food and nutrition professionals should focus on understanding motivators other than health status when exploring adolescent dietary behaviors.
