The Incidence Of Premenstrual Syndrome (PMS) And Characteristics Of Constitutional Type Of Female Univerity Students In Guangzhou

Objective:Based on the Chinese constitution theory, to study the distribution characteristics of constitutional type in Premenstrual Syndrome (PMS) patients. Besides, to analyze the correlation between constitutional type and PMS symptoms severity, find out the some constitutional type which is more likely to have PMS, then some means might be taken to against PMS. It will be a contribution for the prevention of PMS.Methods:1253 female university students were collected. 179 premenstrual syndrome (PMS) cases were selected by present state questionnaire of premenstrual syndrome.179 normal cases were selected randomly from the leaving 1074 normal female university students.179 premenstrual syndrome (PMS) cases were then be divided into mild group and moderate group and severe group by Symptoms of PMS scoring table. All 358 cases were analyzed by TCM physical investigation questionnaire and Chinese constitution classification standards. The incidence of PMS and physical types and distribution of PMS patients were obtained. Applying SPSS16.0 for Windows software, to find out the the relationship between PMS and constitutional type.Results:1.1253 female university students in some medical colleges and universities in Guangzhou were collected,179 cases is PMS, the incidence of PMS is 14.3%. 2. Among 179 PMS cases, the mile is 29.1%, the moderate is 61.5%, the severe is 9.4%. the proportion of the moderate is the biggest.3.16 symptoms of PMS is surveyed in this study, the most frequent symptoms of the first eight are as follows:fatigue and asthenia (85.5%), distending pain in the lower abdomen (82.7%), distending pain in the side abdomen (69.3%), dysphoria and irritation (65.4%), depression (42.5%), working enthusiasm decreasing (42.5%), inattention (41.9%), insomnia and dreaminess (38%), mammary swelling pain (35.2%).4.The distribution of constitutional type shows that:in 179 PMS patients, the more proportion is Qi-deficiency type (48.6%), Qi-depression type (37.4%), Yang-deficiency type (32.4%), blood stasis type (30.2%).On the other hand, the control group is gentleness type (25.1%), Qi-deficiency type (29.1%), Yin-deficiency type (21.2%) and Qi-depression type (19%).The difference of two groups is statistically significant(P< 0.05).5. The constitution type might affect the symptom severity. In the gentleness type, patients with mild symptoms are more than that with moderate or severe symptoms. The difference is statistically significant(P< 0.01). but in the Qi-deficiency type and Yang-deficiency type and Qi-depression type, patients with moderate symptoms are much more than that with mild or severe symptoms. The difference is statistically significant(P< 0.01).6. The result of correlation analysis reveals that the incidence of PMS is related to constitution type, but no Height, weight, Exercise frequency.7. The result of regression analysis reveals that the Qi-depression type and the blood stasis type are more likely to be PMS, however, the Yin-deficiency type, gentleness type and special diathesis type are more not easily to get PMS.Conclusions:1.The incidence of Premenstrual Syndrome(PMS) is 14.3%in this study, it is lower than the reported in the literature. It might be relevant to People features, such as age, living environment, pressure, etc.2. In this study, the proportion of the moderate PMS is the biggest.3. Symptoms like fatigue and asthenia, distending pain in the lower abdomen, distending pain in the side abdomen and dysphoria and irritation are the mostfrequent in PMS.4. The incidence of PMS is related to constitution type, but no Height, weight, Exercise frequency.5. PMS is highly relevant to constitution type. The Qi-depression type and the blood stasis type are more likely to get PMS, however, the Yin-deficiency type, gentleness type and special diathesis type are more not easily to get PMS.6.

In the gentleness type, patients with mild symptoms are more than that with moderate or severe symptoms. but in the Qi-deficiency type and Yang-deficiency type and Qi-depression type, patients with moderate symptoms are much more than others.7. The incidence of PMS and the symptoms severity all can be affected by constitution type, so some means can be taken to prevent it for those are more likely to have PMS.
