Pregnancy-related low back/pelvic girdle pain: Prevalence, severity, and risk factors in Zhengzhou, China

Abstract

BACKGROUND: Pregnancy-related low back pain (LBP) and pelvic girdle pain (PGP) significantly affect the quality of life of pregnant women. Understanding their severity and risk factors may help prevent and alleviate such pain and their resulting dysfunction. OBJECTIVE: This study investigated the prevalence, severity, and biopsychosocial risk factors of pregnancy-related LBP and PGP in Zhengzhou, China. METHODS: The Numeric Pain Rating Scale (NPRS), Chinese version of the Roland-Morris Disability Questionnaire (RMDQ), and other questionnaires were self-administered by 1020 pregnant women undergoing treatment at a tertiary hospital between July and December 2019. Binary logistic regression was used to identify factors associated with pregnancy-related LBP and/or PGP. RESULTS: The prevalence of LBP and/or PGP during pregnancy was 63.0%, and most participants (80.4%) had both. The mean NPRS and RMDQ disability scores were 2.44 ± 2.10 and 6.66 ± 4.65, respectively. A higher gestational body mass index, LBP and/or PGP during menstruation, history of pregnancy-related LBP and/or PGP, and constant pressure were significantly associated with pregnancy-related LBP and/or PGP. Subjective support was a protective factor against LBP and/or PGP. CONCLUSION: The prevalence of LBP and/or PGP was high. The risk factors should be included in routine prenatal care to identify patients at risk of LBP and/or PGP.
