OBJECTIVE The postpartum period is a vulnerable time for sexual health, yet the relationship between biopsychosocial factors and sexual function over time remains unclear. Our aim was to identify trajectories of postpartum sexual function in first-time mothers (N = 646) and examine associations with biopsychosocial factors. METHODS Biopsychosocial factors were assessed at delivery and 3 months postpartum. Sexual function was assessed during pregnancy, 3, 6, and 12 months postpartum using the Female Sexual Function Index. Latent class growth analysis was conducted to identify distinct sexual function trajectories. Multinomial logistic regressions examined associations between biopsychosocial factors and membership in the trajectories. RESULTS Three trajectories were identified: 52% of women reported minimal sexual function problems at 3 months postpartum and improved the least over time, 35% of women reported moderate sexual function problems at 3 months and improved the most over time, and 13% of women reported marked sexual function problems at 3 months and improved somewhat over time. Biomedical factors were not significantly related to trajectory membership. Higher sexual distress at 3 months postpartum was associated with increased odds of being in the moderate and marked sexual function problems subgroups, whereas higher sexual function in pregnancy was associated with decreased odds of being in these subgroups. Lower depressive symptoms and higher relationship satisfaction was associated with reduced odds of being in the marked problems subgroup. CONCLUSIONS Improvement in sexual function postpartum is heterogeneous. Psychosocial, but not biomedical factors were significantly associated with the trajectories. This information may be integrated into psychoeducation, and for informing earlier assessment and intervention practices. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

初生妈妈产后性功能轨迹的生物心理社会预测因子。

目的产后时期是性健康的脆弱时期，但随着时间的流逝，生物心理社会因素与性功能之间的关系仍不清楚。我们的目的是确定初次母亲产后性功能的轨迹（N = 646），并检查与生物心理社会因素的关联。方法在分娩时和产后3个月评估生物心理因素。使用女性性功能指数评估怀孕期间，产后3、6和12个月的性功能。进行潜伏类增长分析以识别不同的性功能轨迹。多项逻辑回归检验了生物心理社会因素与轨迹成员之间的关联。结果确定了三个轨迹：52％的妇女在产后3个月内报告了最小的性功能问题，并且随着时间的推移改善得最少，35％的妇女在3个月后报告了中度的性功能问题，并且随着时间的推移改善得最多，而13％的妇女在产后3个月报告了明显的性功能问题3个月，随着时间的推移有所改善。生物医学因素与轨迹成员关系不显着。产后3个月时较高的性困扰与中度和明显性功能障碍亚组的机率增加有关，而妊娠中较高的性功能与这些亚组的机率降低有关。较低的抑郁症状和较高的人际关系满意度与出现明显问题的可能性降低有关。结论产后性功能的改善是异质的。社会心理因素，而不是生物医学因素与轨迹显着相关。该信息可以整合到心理教育中，并为早期评估和干预实践提供信息。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
