ABSTRACT
<p><b>OBJECTIVE</b>To explore the correlation between syndrome types of late-onset acne female patients and constitutions of Chinese medicine (CM).</p><p><b>METHODS</b>A questionnaire was performed in 365 late-onset acne female patients and 135 healthy subjects (as the control) using Professor WANG Qi's. methods and Standards for Chinese Medical Constitutions Classification.</p><p><b>RESULTS</b>Their CM constitutions were sequenced as damp-heat constitution, yin-deficiency constitution, balanced constitution, yang-deficiency constitution, blood-stasis constitution, qi-stagnation constitution, qi-deficiency constitution, phlegm-damp constitution, inherited special constitution, with statistical difference when compared with those of the control group ( χ2 = 85.206, P < 0.01). In the 365 female late-onset acne patients, 114 (31.23%) were with Chongren imbalance syndrome, 108 (29.59%) were with blood stasis or coagulated phlegm syndrome, 83 (22.74%) were with dampness heat syndrome, and 60 (16.44%) were with wind heat syndrome. There was statistical difference in CM constitution distributions among different CM syndrome types (χ2 = 105.671, P < 0.01). The distribution of CM medical constitutions was different between the two groups. Biased constitutions were often seen in the patient group, while balanced constitution was often seen in the control group. Binary Logistic regression analysis indicated that influencing factors covered sweet food, light diet, roasted food, coffee, stress, work pressure, and family pressure. Of them light diet was one protective factor, while the rest were adverse factors.</p><p><b>CONCLUSION</b>The etiology and syndrome types of female late-onset acne female patients were associated with CM constitution.</p>
