Exploration into the Distribution of Constitutions of Teenagers Based on Latent Class Analysis
Objective:To provide the reference for physical intervention in the teenagers,and to improve their health by investigating the distribution of TCM constitutions of different potential groups of adolescents.Methods:A questionnaire survey was conducted to investigate the exercise habits,sleep status,diet,depression and the constitution of more than 5,000 adolescents;latent class analysis(LCA)was used to explore the best latent class model of health behavior pattern indicators,and χ2 test was used to study the relationship between latent class groups and TCM constitutions.Results:A total of 5285 valid questionnaires were collected in the survey,and the questionnaire validity reached 98.2%;the proportions of male and female were 49.8%and 50.2%respectively;average age was(20.75±1.39)years;the results of LDA showed that four latent class models were the best,named as depression hypomotility type,smoking and drinking type,diet preference type and basic health type respectively;χ2 test showed that the difference in TCM constitutions existed among the population with different health behaviors.Conclusion:Depression hypomotility type is mainly characterized by Qi stagnation constitution,smoking and drinking type by Yin deficiency constitution and Qi stagnation constitution,diet preference type by Qi deficiency constitution and phlegm-dampness constitution,and basic health type by Qi deficiency constitution and Qi stagnation constitution;and the basic health types contain specific constitution and peace constitution,suggesting that targeted health guidance and intervention should be given according to TCM constitutions of different groups of adolescents,in order to raise the teenagers'health.
