The aim of this study was to compare the sexual function of women with and without pregnancy-related PGP, and to investigate its relationship with physical activity (PA), kinesiophobia, and body image (BI). Demographic characteristics, sexual function (Pregnancy Sexual Response Inventory), PA (Pregnancy Physical Activity Questionnaire), kinesiophobia (Tampa Kinesiophobia Scale), and BI (Body Image in Pregnancy Scale) of 125 pregnant women were recorded. In the PGP group (n = 46), visual analogue scales were used to assess the pain intensity during resting and sexual activity, and Pelvic Girdle Questionnaire was used to evaluate the activity limitation. Although total sexual function and BI scores of the groups were similar (p > 0.05), dyspareunia during pregnancy and level of kinesiophobia were higher, and energy expenditure during moderate-intensity PA was lower in pregnant women with PGP (p < 0.05). The PGP group had moderate activity limitation and reported increased PGP intensity during sexual activities (p < 0.001). PA level was significantly correlated with sexual desire (r = 0.180), and overall sexual function was correlated with kinesiophobia (r = -0.344) and BI (r = -0.199) during pregnancy (p < 0.05). These findings suggest that pregnant women with PGP are more vulnerable to sexual dysfunctions, and there is a need to develop biopsychosocial framework-oriented management strategies which aim to improve PA level and to eliminate psychological factors such as kinesiophobia and negative BI.

本研究的目的是比较有和没有妊娠相关 PGP 的女性的性功能，并研究其与身体活动 （PA） 、运动恐惧症和身体形象 （BI） 的关系。记录了 125 名孕妇的人口统计学特征、性功能 （妊娠性反应量表）、PA （妊娠体力活动问卷）、运动恐惧症 （坦帕运动恐惧症量表） 和 BI （妊娠体象量表）。在 PGP 组 （n = 46） 中，使用视觉模拟量表评估静息和性活动期间的疼痛强度，使用 Pelvic Girdle Questionnaire 评估活动限制。尽管各组的总性功能和 BI 评分相似 （p > 0.05），但患有 PGP 的孕妇的妊娠期痛和运动恐惧症水平较高，中等强度 PA 期间的能量消耗较低 （p < 0.05）。PGP 组有中度活动受限，并报告性活动期间 PGP 强度增加 （p < 0.001）。PA 水平与（r = 0.180） 显著相关，总体性功能与怀孕期间运动恐惧症 （r = -0.344） 和 BI （r = -0.199） 相关 （p < 0.05）。这些发现表明，患有 PGP 的孕妇更容易出现性功能障碍，需要制定以生物心理社会框架为导向的管理策略，旨在提高 PA 水平并消除心理因素，如运动恐惧症和负面 BI。
