Psychosomatic aspects of healthy young women with orthostatic dysregulation

The Japanese Edition of the Cornell Medical Index-Health Questionnaire and the Yatabe-Guilford personality test (Y-G Test) was given to 56 young women (mean age 19.2 years) who were identified as having orthostatic dysregulation among a total of 280 healthy young women. The percentage classed as types III (possible neurotic) and IV (probable neurotic) according to the Health Questionnaire was 37.5% in the 56 with orthostatic dysregulation and 9.2% in the controls (n = 65). The percentage classed as types B and E, suggestive of emotional or psychological disturbance according to the personality test, was 59.0% in those with orthostatic dysregulation and 23.1% in the controls. These differences were statistically significant (P < 0.01). Furthermore, there was a significant correlation (P < 0.01) between the two test results for the frequency distribution of the 280 women. These results suggest a possibility that psychosomatic factors influence the occurrence of orthostatic dysregulation in young women, even if these subjects have not sought treatment for dizziness or vertigo, nor for psychosomatic disorders.
