ResearchResearch and Professional BriefUsing Dietary Reference Intake–Based Methods to Estimate Prevalence of Inadequate Nutrient Intake among Female Students in Brazil
Section snippets
Subjects
This was a cross-sectional study to evaluate dietary intake among 119 female nutrition students, aged between 19 and 30 years, at a public university in the state of São Paulo, Brazil, during the 1997 and 1998 school years. Participation was voluntary and the sample loss was 1.65%, due to refusal. Data were collected using a lifestyle and diet questionnaire. The study protocol was approved by the ethics committee of the School of Public Health, University of São Paulo.

Results and Discussion
The present study is the first done in Brazil to assess the adequacy of nutrient intake of women, using data adjusted for day-to-day variability in intake (within-person variation) and recently released Dietary Reference Intakes. As has been clearly demonstrated by the National Research Council (8) and Institute of Medicine (1), adjusting for day-to-day variation in intake may substantially reduce the error when estimating the proportion of a given population group whose intakes are less than a
Conclusions
The diets of the female college students studied did not contain adequate quantities of folate or calcium. The results demonstrate the need for guidance for the population studied to improve intake of these nutrients by means of foods or supplements.
