Motherhood has been associated with reduced leisure-time physical activity (LTPA) levels. We aim to assess maternal LTPA patterns from preconception to 4 years postpartum.
The study was developed with mothers from the Pelotas 2015 Birth Cohort, Southern Brazil (n = 4273). LTPA data were self-reported for preconception, antenatal, and 3, 12, 24, and 48 months postpartum. Information on LTPA referring to preconception (3 mo before pregnancy) and each gestational trimester was retrospectively collected in perinatal. The prevalence of active mothers was calculated according to recommendations (≥150 min/wk). We described changes in LTPA between follow-ups and estimated the probability of mothers being active according to previous LTPA. We used group-based trajectory analysis to identify patterns of LTPA throughout the follow-ups.
The prevalence of active mothers during leisure time decreased in pregnancy and postpartum compared with preconception. At 12 months postpartum, LTPA levels rose again, but at 48 months, the rates of active mothers still had not returned to preconception levels. Prior LTPA engagement was an important determinant of the maintenance of LTPA. Trajectory analysis identified 4 patterns of maternal LTPA, and ∼80% of mothers were allocated to the "always inactive" group. Higher education and income, working outside the home, multiple births, and participating in the PAMELA study intervention were associated with a higher probability of mothers not being included in this predominantly inactive group.
Motherhood is associated with declining rates of women meeting physical activity recommendations during pregnancy and early postpartum.
母亲身份与休闲时间体力活动（LTPA）水平降低有关。我们旨在评估从受孕前到产后 4 年的产妇 LTPA 模式。
该研究是在巴西南部佩洛塔斯 2015 年出生队列中的母亲（n=4273）中进行的。受孕前、产前和产后 3、12、24 和 48 个月时，自我报告 LTPA 数据。受孕前（怀孕前 3 个月）和每个妊娠三期中关于 LTPA 的信息是在围产期回顾性收集的。根据建议（≥150 分钟/周）计算活跃母亲的患病率。我们描述了随访期间 LTPA 的变化，并根据之前的 LTPA 估计母亲活跃的概率。我们使用基于群组的轨迹分析来确定整个随访期间 LTPA 的模式。
与受孕前相比，怀孕期间和产后休闲时间活跃母亲的比例下降。产后 12 个月，LTPA 水平再次上升，但产后 48 个月，活跃母亲的比例仍未恢复到受孕前水平。之前的 LTPA 参与是维持 LTPA 的一个重要决定因素。轨迹分析确定了产妇 LTPA 的 4 种模式，约 80%的母亲被分配到“始终不活跃”组。较高的教育和收入、外出工作、多胎妊娠以及参与 PAMELA 研究干预与母亲不太可能被归入这个主要不活跃组有关。
母亲身份与怀孕期间和产后早期女性满足身体活动建议的比例下降有关。
