Abstract: Objective
To explore the clinical correlation between map tongue and allergic constitution in children.
Methods
According to the selection criteria of allergic constitution，the children in Xiangyang Hospital of Traditional Chinese Medicine were screened from March 2014 to December 2017,and 245 children with allergic constitution and 283 children with nonallergic constitution in the control group were collected. The percentage of children with map tongue and the percentage of the area of map tongue exfoliation in each group were analyzed statistically.
Results
The HardyWeinberg equilibrium law detection was performed in the two groups of children, and they were in accordance with the HardyWeinberg equilibrium law(P>0.05)，indicating that the observed population was representative of the group. There were 72 children with map tongue in allergic constitution group (29.39% ,72/245) and 39 children with map tongue in control group(13.78% ,39/283)， and the incidence in allergic constitution group was significantly higher than that in nonallergic constitution group(P<0.05). There was no significant difference between the two groups in the exfoliation area of tongue(P>0.05).
Conclusion
There is a correlation between map tongue and allergic constitution in children. The incidence of map tongue in children with allergic constitution is higher than that in children with nonallergic constitution.
