Analysis of Traditional Chinese Medicine Constitution and Its Correlation with Syndromes in Adolescents with Non-Suicidal Self-Injury

This paper aims to investigate the distribution of Traditional Chinese Medicine (TCM) constitution and its correlation with TCM syndromes in adolescents with non-suicidal self-injury (NSSI), so as to provide a basis for TCM prevention and treatment of NSSI. The method applied in this paper is to use the TCM Nine Constitution Classification Scale to survey the constitution of 100 NSSI adolescents (NSSI group) and 100 healthy adolescents (control group), and determine TCM syndromes through clinical differentiation. Then, χ² test, Spearman correlation analysis, and logistic regression are used to analyze the correlation between constitution and syndromes. The results show that the detection rates of Qi Stagnation Constitution (46.0%) and Blood Stasis Constitution (18.0%)in the NSSI group are significantly higher than those in the control group (10.0%, 7.0%, all P<0.05), while the Peaceful Constitution (19.0%) is significantly lower than that in the control group (63.0%, P<0.001). The detection rate of Qi Stagnation Constitution in male NSSI patients (55.0%) is higher than that in females (35.0%, P=0.032). TCM syndromes are dominated by Liver Qi Stagnation Syndrome (46.0%). Qi Stagnation Constitution is strongly positively correlated with Liver Qi Stagnation Syndrome (r=0.79, P<0.001) and is an independent risk factor for Liver Qi Stagnation Syndrome (OR=6.15, 95%CI=3.42–11.05). In conclusion, Qi Stagnation Constitution is the core Pianpo constitution in adolescents with NSSI, which is closely related to Liver Qi Stagnation Syndrome. TCM constitution identification can be an important basis for NSSI syndrome differentiation.
