Objectives: This study aims to assess adequacy in micronutrient intake in comparison with
reference nutrient intakes (RNI) and to identify differences in intakes between normal
weight and overweight individuals.
Study design: A sample of 542 university students (18e25 years), normal weight (N ¼ 369)
and overweight (N ¼ 173), was included in a cross-sectional study.
Methods: A three-day diet diary was used to assess energy and nutrient intake. BMI and
waist circumference were measured.
Results: Mean dietary vitamin D intake was lower than RNI in both men (4.44 mg) and
women (5.04 mg). Mean intakes of calcium (597.44 mg), iron (8.62 mg) and folate (171.29 mg)
were also lower than recommendations in women. Weight status (normal weight versus
overweight) was significantly associated with micronutrient intake, and a trend towards a
decrease in vitamin and mineral intake with increasing weight was noted.
Conclusions: Results suggest the need to increase the intake of some micronutrients to meet
the RNI, to ensure optimal health. This study provides a helpful tool to reinforce recommendations
and potential health promotion and intervention strategies in university settings
and could influence manufacturers involved in new food product development
targeted to this young population.
