Self efficacy associated with regression from pregnancy-related pelvic girdle pain and low back pain following pregnancy

Self-efficacy, one's ability to deal with pain, disability, and other symptoms through self-management techniques, positively affect the quality of life in patients with chronic diseases. Pregnancy-related back pain is a common musculoskeletal disorder pre- and postnatally. Hence, the study aimed to determine whether self-efficacy is associated with the development of back pain during pregnancy. Between February 2020 and February 2021, a prospective case-control study was performed. Women with back pain were included. The self efficacy was assessed by the Chinese version of the General Self-efficacy Scale (GSES). Pregnancy-related back pain was measured using a self-reported scale. No regression from pregnancy-related back pain is defined as a recurrent or persistent pain score ≥ 3 over a week around 6 months postpartum. Women experiencing back pain during pregnancy are classified according to whether having a regression. This problem can be divided into pregnancy-related low back pain (LBP) and posterior girdle pain (PGP). The differences in variables were compared between groups. A total of 112 subjects have completed the study finally. These patients were followed up with an average of 7.2 months after childbirth ranging from six to 8 months. 31 subjects (27.7%) of the included women did not report regression 6 months postpartum. The mean self efficacy was 25.2 (SD:10.6). Patients with no regression tended to be older (LBP:25.9 ± 7.2 vs.31.8 ± 7.9, P = 0.023; PGP: 27.2 ± 7.9 vs. 35.9 ± 11.6, P
