Objectives of the Study: This study aimed to examine demographic disparities and 5-y longitudinal and secular trends (1999–2004) in whole-grain intake among 2 cohorts of Minnesota adolescents.
Results: In 1999, 11% of adolescent males and 13% of adolescent females reported that they consumed more than one daily serving of whole grains. Whole-grain intake was lowest among youth of the Native American and white races and among youth of high socioeconomic status. During the transition from middle to late adolescence, whole-grain intake increased by a mean of 0.14 daily servings among adolescent males and 0.09 daily servings among adolescent females. No significant changes in whole-grain intake were shown among either sex during the transition from early to middle adolescence. Yeast breads, popcorn, and ready-to-eat breakfast cereals were major sources of whole grains in 1999 and 2004.
Conclusion: Findings suggest the need to advance efforts that target improvements in the amount of whole-grain foods selected by adolescents.
