| ObjectiveTo explore the incidence of primary menorrhalgia, condition of menorrhalgia, relevant factors, reasons to aggravate or cause menorrhalgia, methods to release menorrhalgia, condition of help-seeking for menorrhalgia, condition of Chinese medicine syndrome classification and relevance of Chinese constitution type to menorrhalgia, the cross-sectional investigation study of female patients with primary menorrhalgia in Tai Wan area, was undertaken.MethodsInvestment questionnaire was distributed to female patient who came to the clinic. After reclaim of questionnaires, patients were divided into group of primary menorrhalgia and group of non-primary menorrhalgia according to diagnosis criteria of Western medicine and Chinese medicine. Then incidence of menorrhalgia, severity of menorrhalgia, relevant risk factors of menorrhalgia,relevance of Chinese medicine syndrome distribution to constitution type were analyzed.ResultsIn the study,464 investigation questionnaires were reclaimed, after 35 ones of error and negligence, contradiction and defect, were excluded,429 ones remained, and the effective response rate was 92.46%. In the 429 investigation questionnaires,111 ones were patients with primary menorrhalgia and 318 ones were non-primary menorrhalgia.1. In the primary menorrhalgia group, the average age of patients was 18.87±1.23 years, the average weight was 52.45±9.53Kg, the average height was 160.09±6.12cm. Compared with those of control group, there was no difference (P>0.05).2. Among non-primary menorrhalgia patients,there were 218 cases Gynecology diseases, accounting for 66.98%, such as Uaginitis,Uterine Cervicitis, Pruritus Vulvae, Condylomata Acuminata, Hysteromyoma, Polycystic Ovary Sundrome,Sterility. The statistics reflect Uaginitis, Pruritus Vulvae, Sterility were the most common diseases in young female.3. In the cross-sectional investigation, there were 111 cases with primary menorrhalgia, accounting for 25.87% of the total effective cases; and the incidence of primary menorrhalgia was 27%(116/429). Among them, patients with slight pain accounting for 28.83%, moderate pain as 54.95% and serious pain as 9.91%.4. In the observation group, there were four patients who addicted to eat hot and pungent, occupying 3.6%; and in the control group, there were five patients who addicted to eat hot and pungent, occupying 11.57%. In the observation group, there were sixty nine patients addicting to hot and pungent, raw or cold food, occupying 62.16%; and in the control group, there were two hundreds and eleven patients addicting to hot and pungent, raw or cold food, occupying 66.35%. Though the cases in the observation group were less than that in the control group, but there was no significant difference (P>0.05).5. In the observation group,63.96% cases had symptoms of difficulty to fall asleep, then 28.83% cases had symptoms of dreaminess; yet in the observation group,48.74% cases had symptoms of difficulty to fall asleep, then 44.65% cases had symptoms of dreaminess. Cases that had difficulty to fall asleep in the observation were far more than those in the control group, and only 3.60% cases with good quality of sleep. Sleep quality had significant difference statistically in two groups (P<0.05), which indicated that quality of sleep was relevant to primary menorrhalgia.6. In the investigation, there was no relevance of primary menorrhalgia to sport habit, menarche age, menstrual cycle, menstrual period and distribution of blood type.7. Syndrome of damp-heat-static blood blocking was the most common syndrome in both groups, and syndrome of deficiency of liver and kidney was the second. There was no statistic significant difference of Chinese medicine syndrome distribution in two groups (P>0.05). 8. In the observation group, arrangement of constitution distribution from high to low was dull and obscure constitution(48,43.24%), greasy and stagnate constitution (41,36.94%), dry and heat constitution(20,18.02%), slow and cold constitution(1,0.90%), normal constitution(1,0.90%) and fatigue and trance constitution(0,0.00%). In the control group, arrangement of constitution distribution from high to low was dull and obscure constitution(141,44.34%), greasy and stagnate constitution((128,40.25%), dry and heat constitution (43,13.52%), slow and cold constitution (4,1.26%), fatigue and trance constitution(2,0.63%) and normal constitution(0,0.00%). Distribution of constitution type had no significant difference analyzed by chi-square analysis (P>0.05).ConclusionsResults of the investigation showed primary menorrhalgia was relevant to quality of sleep, and patients with dull and obscure constitution or greasy and stagnate constitution could be sensitive to had primary menorrhalgia; and syndrome of damp-heat-static blood blocking was the most common type of primary menorrhalgia.
