Pregnancy can significantly alter posture and stability, thereby affecting spine curvatures. A positive relationship between the number of full-term pregnancies and the prevalence of low back pain (LBP) has been reported previously. This study aimed to analyze the impact of pregnancy on spine posture and LBP. Thirty pregnant females who were nulliparous (Group 1, n = 15) or had one or two pregnancies (Group 2, n = 15) were examined using the photogrammetric method in the first, second, and third trimesters of pregnancy. Further, a correlation analysis was conducted among the body mass index (BMI), pain intensity (VAS scale), and spine posture parameters. The parous groups did not differ significantly in the parameters of the spinal posture. The thoracic angle decreased in trimester II compared to trimester I (157.77° vs. 160.55°, = 0.004), which, according to the measurement methodology used, means that the thoracic kyphosis curvature increased. BMI was associated with the angle of trunk inclination in trimester I in Group 1 ( = 0.54, = 0.04), as well as with the thoracic angle in trimesters II and III in Group 2 ( = 0.54-0.62, < 0.05). A statistically significant correlation between pain intensity and spine posture parameters was more frequently observed in Group 2. Parity does not affect spine posture during pregnancy or pain intensity. The intensity of LBP was associated with spine posture changes during pregnancy, but the character of association differs between groups of parity. Alterations in spine posture should be monitored during pregnancy to prevent back pain.
怀孕会显著改变姿势和稳定性，从而影响脊柱曲度。此前已有报道称足月妊娠次数与下背痛（LBP）患病率之间存在正相关关系。本研究旨在分析怀孕对脊柱姿势和LBP的影响。对30名未生育的怀孕女性（第1组，n = 15）或有过一次或两次怀孕经历的女性（第2组，n = 15）在妊娠的第一、第二和第三个月使用摄影测量法进行检查。此外，还对体重指数（BMI）、疼痛强度（视觉模拟量表）和脊柱姿势参数进行了相关性分析。经产组在脊柱姿势参数方面没有显著差异。与妊娠第一个月相比，妊娠第二个月胸椎角度减小（157.77°对160.55°，P = 0.004），根据所使用的测量方法，这意味着胸椎后凸曲度增加。在第1组中，BMI与妊娠第一个月的躯干倾斜角度相关（r = 0.54，P = 0.04），在第2组中，BMI与妊娠第二和第三个月的胸椎角度相关（r = 0.54 - 0.62，P < 0.05）。在第2组中更频繁地观察到疼痛强度与脊柱姿势参数之间存在统计学显著相关性。产次在怀孕期间不影响脊柱姿势或疼痛强度。LBP的强度与怀孕期间脊柱姿势的变化有关，但不同产次组之间的关联特征有所不同。怀孕期间应监测脊柱姿势的变化以预防背痛。
