Objective: This study was carried out to examine the frequency of lumbopelvic pain in pregnant women, the level of disability associated with it, and the factors that may affect the level of disability. Methods: The descriptive, cross-sectional and analytical study was carried out with 381 pregnant women who received service from the routine pregnancy follow-up outpatient clinic of a state hospital. A form including demographic, obstetric, and other descriptive characteristics of the cases, a visual pain zone diagram to determine the pain area, and the Roland–Morris Disability Questionnaire (RMDQ) to determine the disability level were used as data collection tools. Descriptive statistical methods and non-parametric tests were used in the analysis of the data. Results: It was determined that 86.35% (n=329) of the participants had lumbopelvic pain and were mildly disabled according to the RMDQ total score (12.0 ± 7.3). In the analysis performed according to subgroups, the mean RMDQ scores of pregnant women with pelvic girdle pain were found to be statistically significantly higher than those with low back pain (P < .05). Other variables associated with high disability scores were education level, parity, occupation, gestational week (trimester), presence of lumbopelvic pain in the previous pregnancy, work stress, and negative sexual life history (P < .05). Conclusion: Lumbopelvic pain is a condition that is common in pregnancy, can cause differ ent levels of disability depending on some factors, and should not be ignored by antenatal care providers.
