尽管孕前体重指数（BMI）、妊娠体重增加（GWG）和产后体重（PPW）之间存在密切关系，但这些因素往往被单独研究。没有数据表明非洲城市人口中孕妇和产后妇女的纵向体重轨迹。我们研究了母亲从怀孕到产后12个月的体重轨迹，与较高体重轨迹班级成员相关的因素以及体重轨迹与12个月婴儿生长的关联。使用潜在级生长模型，研究了989名妇女从怀孕第一次产前检查到产后12个月的体重轨迹。使用多项逻辑回归评估与班级成员相关的基线因素。在参与研究的妇女中，613名婴儿在12个月时接受了生长发育评估。母亲和婴儿的人体测量由训练有素的研究护士进行。采用线性回归分析母体体重轨迹等级与婴儿12月龄体重（WAZ）、年龄身高（LAZ）、体重身高（WLZ）之间的关系。确定了四种不同类型的母亲体重轨迹。类别包括一致的低（29%）、一致的中（37%）、中高（24%）和一致的高（10%）轨迹。与观察到的中高水平轨迹趋势相似，与持续高级别成员呈正相关的基线因素包括年龄（OR 1.05, 95% CI 1.01-1.09）、孕前BMI （OR 2.24, 95% CI 1.97-2.56）、1期高血压（OR 3.28, 95% CI 1.68-6.41）、血红蛋白水平（OR 1.39, 95% CI 1.11-1.74）和胎次（OR 1.39, 95% CI 1.15-1.67）；感染HIV （OR 0.47, 95% CI 0.30-0.74）呈负相关。在调整分析中，与一致的中等体重轨迹相比，一致的低体重轨迹（平均差值-0.41,95% CI -0.71;-0.12）与12月龄婴儿WAZ下降相关，一致的高体重轨迹（平均差值1.21,95% CI 0.59-1.83）与婴儿WAZ增加相关。确定独特的纵向体重轨迹分组可能为改善健康的母亲体重和婴儿结局的综合努力提供信息。在线版本包含补充材料，可在10.1186/s12889-023-16963-3获得。
Despite the close relationship between pre-pregnancy body mass index (BMI), gestational weight gain (GWG) and postpartum weight (PPW), these factors are often studied separately. There are no data characterising longitudinal weight trajectories among pregnant and postpartum women in urban African populations. We examined maternal weight trajectories from pregnancy through to 12 months postpartum, factors associated with higher weight trajectory class membership and associations of weight trajectories with infant growth at 12 months. Data from 989 women were examined for weight trajectories from first antenatal care visit in pregnancy to 12 months postpartum using latent-class growth models. Baseline factors associated with class membership were assessed using multinomial logistic regression. Of the enrolled women, 613 of their infants were assessed for growth at 12 months. Anthropometry measurements for mothers and infants were conducted by a trained study nurse. Associations between maternal weight trajectory class and infant weight-for-age (WAZ), length-for-age (LAZ), weight-for-length (WLZ) at 12 months of age were analysed using linear regression. Four distinct classes of maternal weight trajectories were identified. The classes included consistent low (29%), consistent medium (37%), medium–high (24%) and consistent high (10%) trajectories. Similar to trends observed with medium–high trajectory, baseline factors positively associated with consistent high class membership included age (OR 1.05, 95% CI 1.01–1.09), pre-pregnancy BMI (OR 2.24, 95% CI 1.97–2.56), stage 1 hypertension (OR 3.28, 95% CI 1.68–6.41), haemoglobin levels (OR 1.39, 95% CI 1.11–1.74) and parity (OR 1.39, 95% CI 1.15–1.67); living with HIV (OR 0.47, 95% CI 0.30–0.74) was inversely associated. In adjusted analyses, compared to consistent medium weight trajectory, consistent low weight trajectory (mean difference -0.41, 95% CI -0.71;-0.12) was associated with decreased, and consistent high weight trajectory (mean difference 1.21, 95% CI 0.59–1.83) with increased infant WAZ at 12 months of age. Identification of unique longitudinal weight trajectory groupings might inform comprehensive efforts targeted at improving healthy maternal weight and infant outcomes.
