Evaluation of energy, nutrient and dietary fiber intakes of adolescent males.
J Am Coll Nutr 2007; 26(3):264-71JA

Abstract

OBJECTIVE

The minimal data available on the current energy, nutrient and dietary fiber intakes of adolescent males challenges the development of effective nutrition education programs. There is a need for research into the current intakes of adolescent males and in particular their relation to the current Dietary Reference Intakes (DRIs). The primary objective of this study was to assess the diet of adolescent males and relate energy, nutrient and dietary fiber intakes to the DRIs. Secondary objectives were to relate energy, macronutrient and dietary fiber intakes to body mass index (BMI)-for-age percentile categories as well as to explore vitamin/mineral supplement use and soft drink consumption.

METHODS

Three-day food records were completed by 180 healthy adolescent males for analysis of energy, nutrient and dietary fiber intakes from food and supplements. Following adjustment for intra-individual variability, nutrient intake percentile distributions were related to the DRIs. Energy, macronutrient and dietary fiber intakes were compared among BMI-for-age percentile categories and diets were evaluated for vitamin/mineral supplement use and soft drink consumption.

RESULTS

Median intakes for percent energy from carbohydrate, fat and protein were within the Accepted Macronutrient Distribution Ranges. Intakes of micronutrients with Estimated Average Requirement values indicated that greater than 50% of subjects consumed inadequate amounts of vitamin A and vitamin B6, and greater than 75% of subjects consumed inadequate amounts of magnesium, phosphorus and zinc. Subjects classified as overweight had significantly lower energy and carbohydrate intakes compared with subjects classified as having an acceptable body weight. The prevalence of vitamin/mineral supplement use was 16.1% and 67% of subjects reported daily consumption of soft drinks.

CONCLUSION

Results of this study reveal that adolescent males are consuming the recommended amounts of macronutrients but may be at risk for consuming inadequate levels of specific micronutrients. Nutrition education programs should consider targeting select micronutrients to improve nutritional intakes of adolescent males.
