Prevalence and factors associated with lumbopelvic pain among pregnant women in their third trimester: a cross-sectional study.

Introduction: pregnancy related lumbopelvic pain, which refers to low back pain and pelvic girdle pain, is a common musculoskeletal disorder affecting quality of life. The purpose of this study was to establish the prevalence and the factors associated with lumbopelvic pain among pregnant women in their third trimester. Methods: four hundred and nineteen pregnant women were included in this institutional-based cross-sectional study. The study was carried out from October 2018 to March 2019 at Kawempe national referral hospital in Uganda. Pregnant women in the third trimester participated in the study. Pregnant women with preexisting backache, a fracture or surgery to the back, hip or pelvic area in the preceding 12 months were excluded. Lumbopelvic pain was defined as low back pain and pelvic girdle pain. Bivariate and multivariable logistic regression were carried out to establish the factors associated with lumbopelvic pain. The presence of lumbopelvic pain was assessed for and diagnosed using the illustrations in the pelvic girdle questionnaire. Results: the prevalence of pregnancy related lumbopelvic pain was 46% (95% CI: 40.8-50.4). Most women who had pregnancy related lumbopelvic pain experienced lumbar pain. The factors independently associated with pregnancy related lumbopelvic pain (PLPP) were being HIV sero positive [adjusted odds ratio (AOR) 2.25, 95% CI: 1.17-4.35] and having no monthly income (AOR 0.53, 95% CI: 0.30-0.94). Conclusion: in this study, PLPP is common in women attending antenatal clinic in their third trimester. The factors associated with PLPP were being HIV positive and having no income. In future pregnant women who come for antenatal care with pregnancy related lumbopelvic pain should be given appropriate advice and support.
