Perinatal low back and pelvic girdle pain (LBPGP) are very common symptoms. In Japan, where the birthrate is declining and the population is aging rapidly, it is one of the most urgent issues to be solved. It is important to gain knowledge on perinatal LBPGP as one of the countermeasures against the declining birthrate in Japan. In this study, a questionnaire survey was conducted among expectant and nursing mothers to understand the current status of LBPGP. If the current status of LBPGP among expectant and nursing mothers can be ascertained through this study, it may lead to the development of preventive measures.

Questionnaires were distributed at obstetrics and gynecology offices, and responses were obtained from 35 pregnant women. Pelvic pain, mainly in the buttocks and groin area, was observed in approximately 30% of pregnant women in the perinatal period. The site was more common in the posterior pelvic region than in the lumbar region and was considered to be around the sacroiliac joint area. Compared to women of the same age group, seven of the eight SF-36 national reference values were lower in the pregnant women who participated in this study.It is necessary to examine measures to prevent and improve low back and pelvic pain during the perinatal period.

The results of present study, including data to be collected in the future and data that is currently unanalyzed, will be published as academic conferences and papers at domestic and overseas.
