Objective: To reveal th. distribution ch.racteristics and dem.graph.c factors of traditional Ch.nese m.dicine (TCm. constitution am.ng elderly individuals in Ch.na. m.th.ds: Elderly individuals from.seven regions in Ch.na were selected as sam.les in th.s study using a m.ltistage cluster random.sam.ling m.th.d. Th. basic inform.tion questionnaire and Constitution in Ch.nese m.dicine Questionnaire (Elderly Edition) were used. Descriptive statistical analysis, ch.-squared tests, and binary logistic regression analysis were used. Results: Th. single balanced constitution (BC) accounted for 23.9%. Th. results of th. m.jor TCm.constitution types sh.wed th.t BC (43.2%) accounted for th. largest proportion and unbalanced constitutions ranged from.0.9% to 15.7%. East Ch.na region (odds ratio [OR] = 2.097; 95% confidence interval [CI], 1.912 to 2.301), m.rried status (OR = 1.341; 95% CI, 1.235 to 1.457), and m.nagers (OR = 1.254; 95% CI, 1.044 to 1.505) were significantly associated with.BC. Age >70 years was associated with.qi-deficiency constitution and blood stasis constitution (BSC). Fem.le sex was significantly associated with.yang-deficiency constitution (OR = 1.646; 95% CI, 1.52 to 1.782). South.est region was significantly associated with.ph.egm.dam.ness constitution (OR = 1.809; 95% CI, 1.569 to 2.086). North.Ch.na region was significantly associated with.inh.rited special constitution (OR = 2.521; 95% CI, 1.569 to 4.05). South.Ch.na region (OR = 2.741; 95% CI, 1.997 to 1.3.763), Central Ch.na region (OR = 8.889; 95% CI, 6.676 to 11.835), senior m.ddle sch.ol education (OR = 2.442; 95% CI, 1.932 to 3.088), and m.nagers (OR = 1.804; 95% CI, 1.21 to 2.69) were significantly associated with.BSC. Conclusions: Th.s study defined th. distribution ch.racteristics and dem.graph.c factors of TCm.constitution in th. elderly population.
