Purpose: Although premsnstrual syndromes(PMS) have long been recognized, there has been difficulty to evaluate the symtoms. Usually the questionnaire has been used to dignose the PMS. Objective is to investigate the relationship of body temperature between women with PMS and without PMS. Methods: We studied 23 patients visiting OO hospital from 26th December 2005 to 26th April 2006. The Questionnaire for PMS was used to evaluate physical, emotional, and behavioral symptoms accompanying the menstrual cycle of the subjects. The subjects were categorized in two groups, non-PMS(11) and PMS group(12). Body temperature was assessed by Dorex spectrum 9000MB (DOREX Inc., USA). We measured CV4, CV3, CV12 and CV17 to evaluate the distribution of body temperature, compared the difference of temperature(${Delta}T$) between CV17-CV4, CV17-CV3, CV17-CV12 and CV12-CV3. We investigated the of temperature and ${Delta}T$ between two groups by Mann-Whitney U-test. Results: The temperature of CV3 and CV4 of PMS located in low abdomen were lower than those of non-PMS located in chest. But there was no statistical significance of temperature between two groups. There was lower temperature of low abdomen in PMS group than non-PMS group without statistical significance. Conclusion: The results suggest that DITI could be useful to assess the PMS objectively. But more research should be needed.
