title: BMI, pain and hyper-mobility are determinants of long-term outcome for women with low back pain and pelvic pain during pregnancy.
abstract: Low back pain and pelvic pain (LBPP) is common during pregnancy and up to 40% of women still have symptoms half a year after delivery. The aim of the study was to investigate determinants and the prevalence of persistent LBPP after pregnancy in a Swedish cohort. In a previous study 891 women had responded to a questionnaire on risk factors and prevalence of LBPP during pregnancy. Altogether 72% (n=639) of the women had reported LBPP during pregnancy. These respondents were sent a second questionnaire at approximately 6 months after delivery. The response rate was 72.6% (n=464). Independent t-test and Pearson's chi-squared test were used to test the difference between the two groups. In response to the questionnaire, 43.1% of the women reported persistent LBPP 6 months after delivery. Women with persistent LBPP after pregnancy had had significantly earlier onset of pain during pregnancy, higher maternal age, higher body mass index (BMI), and assessed a higher level of pain due to LBPP during pregnancy and after pregnancy, and included a higher proportion of women with joint hyper-mobility. In summary, recurrent or continuous LBPP is prevalent after pregnancy. BMI as well as hyper-mobility are prominent determinants of persistent LBPP after pregnancy. Level and onset of pain during pregnancy were strong predictors of persistent LBPP.
