Abstract

Purpose

Attrition of participants over time poses a challenge in longitudinal research. This study aimed to explore how partner participation influenced maternal retention.

Methods

Using data from the P3 Cohort (a longitudinal pregnancy cohort), study retention was assessed at each stage of data collection up to 1 year postpartum. Participants were grouped according to their partner's level of participation in the study (participants who did not consent to the study team contacting their partners, participants whose partners were contacted but did not consent to participate, and participants whose partners actively participated). Cox proportional hazards models were used to evaluate the association between partner participation and participant attrition.

Results

Of 2194 eligible participants, 38.9 % did not provide consent for the study team to contact their partner, and 42.1 % of partners that were contacted agreed to participate in the cohort. Retention rates in the cohort were high (97.5 % at 1 year postpartum) but varied by partner participation. Partner participation was associated with a significantly reduced hazard of attrition (HR=0.38, 95 % CI:0.15–0.92).

Conclusions

Active partner participation significantly enhances maternal participant retention. Inclusion of partners in pregnancy research may help reduce attrition and gain a more comprehensive understanding of family dynamics.

夫妇与个人参与妊娠研究的影响：参与者特征和研究保留的比较分析。

目的：随着时间的推移，参与者的流失对纵向研究提出了挑战。本研究旨在探讨伴侣参与如何影响母亲保留。方法：使用P3队列（纵向妊娠队列）的数据，在数据收集的每个阶段评估研究保留情况，直至产后1年。参与者根据其伴侣参与研究的程度进行分组（不同意研究小组联系其伴侣的参与者，联系了其伴侣但不同意参与的参与者，以及其伴侣积极参与的参与者）。采用Cox比例风险模型评价同伴参与与参与者流失之间的关系。结果：在2194名符合条件的参与者中，38.9%的人没有同意研究小组联系他们的伴侣，42.1%的被联系的伴侣同意参加队列。队列中的保留率很高（产后1年为97.5%），但因伴侣参与而异。伴侣参与与人员流失风险显著降低相关（HR=0.38, 95% CI:0.15-0.92）。结论：积极的伴侣参与显著提高了母亲参与者的保留。在怀孕研究中纳入伴侣可能有助于减少损耗，并对家庭动态有更全面的了解。
