Abstract:
Objective
To work out a classification of TCM constitution at different ages by investigating the children aged 0 to 6 in Wuhan, in order to provide guidance for TCM health care in healthy children.
Methods
By cross-sectional survey, the healthy children aged 0 to 6 were divided into 4 age groups, and the questionnaire survey on TCM constitution was performed in them.
Results
A total of 350 valid questionnaires were collected, which showed that the distribution of mild constitution was 65%(228/350), biased constitution 35%(122/350).When the children grew older, the percentage of mild constitution was decreasing(84% to 52%), while that of biased constitution was increasing(16% to 48%), in which the percentage of combined constitution was increasing(0% to 30%). The constitution distribution of different age groups had their own features. In lung-deficiency constitution, the difference on Tebing constitution was of statistical significance(P<0.05),which meant that the lung-deficiency constitution was often combined with Tebing constitution. There was statistical difference on the probability of being biased constitution in the children whose parents only had middle school education or lower(P<0.05).
Conclusion
The distribution percentage of TCM biased constitution in children aged 0 to 6 in Wuhan increases with the increase of age and also becomes complex, and different age group has different features, which indicates that it is of practical significance to divide the children into 4 age groups. It also shows that attention should be paid to different points in different groups during the constitution intervention. In the treatment it's necessary to pay attention to different features and perform treatment based on constitutions differentiation in order to improve the effect.
