Objectives: To determine the validity and reproducibility of a food frequency questionnaire (FFQ) in order to assess calcium intake in women. Design: Longitudinal and prospective study. Location: Homes of Nutrition EAP students’ family environment in Lima. Participants: Women volunteers 30 to 50 year-old. Methods: Seventy-eight women volunteers 30 to 50 year-old were trained to keep food records (REC) for 7 days in two distinct periods four months apart. In the second period a FFQ survey with 24 food and preparations in normal portions was applied. Correlation was determined with Spearman rho and Kappa coefficient, as well as FFQ sensitivity and specificity; we present a Bland and Altman graphic. Main outcome measures: Milligrams of calcium consumed by REC and FFQ. Results: Mean calcium intake for 14 days obtained by 24 h record was 415 mg ± 130.4 mg for FFQ1 and 490 mg ± 338.3 mg fo...
