Mizaj assessment and data analysis methods in Amirkola health and aging project (AHAP cohort).

Abstract

One of the principles of Persian medicine (PM) is the individualized approach that is presented with the concept of Mizaj. In this viewpoint, on the whole body, Mizaj is determined for every person based on 10 criteria, which is a result of the Mizaj of the main organs, including the brain, liver, and heart. There is no standard diagnostic tool for Mizaj assessment yet. The purpose of this study is to explain the method of Mizaj assessment and data analysis in the elderly in one of the biggest health and aging projects in Iran. The second phase of the Amirkola health and aging project (AHAP) evaluated more than 1,700 clinical and laboratory examinations of 2135 elderly people. In this study, a novel Mizaj assessment method in two phases is presented. In the first phase, 1541 elderly were assessed by a PM expert and typical diagnoses (the high confidence of expert's proficiency) were determined. At the second phase, an expert panel including 5 PM experts evaluated the cases. The data of the elderly whose Mizaj agreed in the expert panel was used to assess its correlation with Mizaj. Also, the Mizaj of the main organs of these cases was evaluated this way. In the lack of valid and reliable questionnaires to assess the personalized viewpoint of PM, a new expert-based method has been introduced that can be used in similar studies. The result of the Mizaj assessment in this way will be used to obtain objective values for the Mizaj assessment.
