International Journal of Epidemiology 1995 ; 24 : 763-770. Background. There is growing interest in the potential role of calcium in the prevention of osteoporosis. Therefore a quantitative dairy questionnaire (DO) was developed to estimate the calcium intake from dairy products. The aim of this study was to evaluate the relative validity and reproducibility of the DO in 27-29 year old males and females. Methods. The DO was validated against a cross-check dietary history method (DH) in 160 subjects, and the reproducibility was assessed in 29 subjects by repeating the administration of the DO with a one-year interval. Results. In the validity study, the nutrient calcium and the food groups cheese and milk and milk products measured by the DO tend to show higher intakes as compared to the results of the DH. However, only for the calcium intake was the difference between the DO and DH (7%) significant. The Bland-Altman plot showed that this bias was constant over the range of calcium intakes. Conclusions. These data indicate that the DO is reasonably accurate in young adults as a means of assessing the calcium intake from dairy products.
