Dairy products frequency questionnaire (ADOS-CA) calibration for calcium intake evaluation

Abstract

2test) in calcium intake classes ( 90% of RDI = no calcium deficiency risk). Moreover sensitivity, specificity and accuracy indices were calculated for the prepared test. No differences between mean calcium intake from dairy products estimated by the ADOS-Ca test and the 24-hour recall method repeated seven times (men: 619 mg vs. 661 mg; p=0.263; women: 434 mg vs. 442 mg; p=0.645) were revealed, but calcium intake correlation was noted. No differentiation in the population distribution in three calcium intake classes was noted, and the percentage of people classified accurately into the same class by the ADOS-Ca test and the 24-hour recall method repeated seven times was high (71% of the population). The noted high sensitivity index value (88%), shows high ability of the test to classify people properly to a group under calcium deficiency risk. The prepared ADOS-Ca diagnostic test was proved to be a good tool for quantitive evaluation of calcium intake from dairy products and enabled accurate classification of people with different calcium intake with regards to risk of its deficiencies.
