There is little information regarding food practices of Puerto Rican children and information about the adequacy of their diet, particularly of vitamin C intake. This cross-sectional study aimed to assess the diet, particularly in terms of vitamin C content, of a representative sample of children from private and public elementary (first to sixth grade) schools in Cayey, Puerto Rico. A two-stage stratified cluster sampling design was used (n=251). Information was collected using a personal interview of the child, a 24-hour recall, and by taking physical measurements (weight, height). Chi-square and Fisher tests were used to compare proportions. Means were compared using ANOVA and T-tests. Half of the students were male (51%); mean age was 9±2 years. About 28% of students did not reach dietary recommendations (RDI's) for vitamin C, with an average intake of 164±468 mg (median=79 mg). More girls (79%) than boys (64%) reached RDI's, with a higher average intake (186 vs. 143 mg). Younger students (≤8 y/o) reached RDI's better than those >8 y/o (77% vs. 69%). However, average intake was lower among younger students (96 vs. 196 mg). More children with healthy weight (74%) reached RDI's than overweight or at risk of overweight students (67%). The lowest average intake was reported among overweight children. Vitamin C intake considerably exceeds RDI's, which could be associated to a high intake of vitamin-added fruit beverages.

Learning Objectives: 1. Assess vitamin C dietary intake of elementary school students in Puerto Rico.
2. Identify subgroups of elementary school students who do not reach dietary recommendations for vitamin C consumption.
3. Identify nutritional needs of Puerto Rican children for nutritional interventions.
