Background:
The process of diagnosis and treatment in Persian medicine (PM) are based on the concept of Mizaj (temperament). Among the indices of Mizaj determination, anthropometric indices are less influenceable regarding age change and other environmental factors. The purpose of this study was to investigate the relationship between anthropometric indices and Mizaj.
Methods:
Four PM experts determined the Mizaj of 121 participants. Those who had ≥70% agreement in their Mizaj determination by the experts were selected and their anthropometric indices were measured. The best cutoff point of each index and its relationship with the defined Mizaj were extracted using Receiver Operative Characteristic Curve and Binary Logistic Regression.
Results:
52 out of 121 participants entered the main study. The warm-Mizaj people had larger dimensions in height, shoulder, chest, palm and sole width, and head height. Cold-Mizaj people had smaller dimensions in weight, height, shoulder, chest and head. High levels of BMI, chest depth and head dimensions had the highest correlation with the wet Mizaj and lower dimensions of these indices had the highest correlation with the dry Mizaj.
Conclusion:
Among the anthropometric indices, chest, palm, sole dimensions, head height and weight had the highest correlation with warmness/coldness and BMI, head width and chest dimensions had the highest correlation with wetness/dryness. The BMI which is more closely related to the soft tissue, only correlates with the wetness/dryness, while, bone dimensions are associated with warmness/coldness. Further studies are needed to metricize the anthropometric indices for Mizaj determination.
Insights
Persian medicine uses Mizaj (temperament) for diagnosis. This study found correlations between body measurements (anthropometric indices) and Mizaj, suggesting potential for objective temperament assessment.
Area of Science:
- Integrative medicine
- Anthropometry
- Traditional Persian Medicine
Background:
- Persian medicine (PM) diagnosis and treatment rely on the concept of Mizaj (temperament).
- Anthropometric indices offer a stable measure for Mizaj determination, less affected by age and environment.
- Understanding the link between physical measurements and Mizaj is crucial for advancing PM diagnostic tools.
Purpose of the Study:
- To investigate the relationship between anthropometric indices and Mizaj in individuals.
- To identify specific body measurements that correlate with different Mizaj types.
Main Methods:
- Mizaj determination by four PM experts for 121 participants.
- Selection of participants with ≥70% expert agreement for anthropometric measurements.
- Analysis using Receiver Operative Characteristic Curve and Binary Logistic Regression to find correlations.
Main Results:
- Warm-Mizaj individuals exhibited larger dimensions in height, shoulder, chest, palm/sole width, and head height.
- Cold-Mizaj individuals showed smaller dimensions in weight, height, shoulder, chest, and head.
- High BMI, chest depth, and head dimensions correlated with wet Mizaj; lower dimensions correlated with dry Mizaj.
Conclusions:
- Specific anthropometric indices like chest, palm, sole dimensions, head height, and weight correlate with warmness/coldness.
- BMI and head/chest dimensions correlate with wetness/dryness, distinguishing soft tissue from bone associations.
- Further research is needed to develop metricized anthropometric indices for objective Mizaj assessment in Persian medicine.
