To identify maternal characteristics associated with 24-month postpartum weight retention.
Data were collected from the 2016 Los Angeles Mommy and Baby (LAMB) Follow-Up Survey, a population-based prospective cohort study that assesses maternal and infant health in Los Angeles County. In 2014, LAMB initially surveyed 6035 women 6 months following a live birth. The 2016 LAMB Follow-Up reevaluated this same cohort after the index child's second birthday. 2679 women completed 2016 LAMB Follow-Up (52% adjusted response rate). The final sample size was 1524 after excluding subjects with subsequent pregnancies after the index child and missing information for postpartum weight. Eight predictors were included in this analysis: gestational weight gain, pre-pregnancy BMI, exercise, depressed mood since having child, age, race, education, and job loss during pregnancy. Chi-square tests and logistic regression analyses were performed using SAS 9.3.
Two years after delivery, women with postpartum weight retention weighed on average of 15.3 lb. more than before the index pregnancy. Women were more likely to retain postpartum weight when they exceeded gestational weight gain guidelines (AOR = 2.03, 95% CI = 1.40-2.93), did not exercise (AOR = 3.32, CI = 1.85-5.98), were between ages 20-29 (AOR = 1.54, CI = 1.01-2.36), were Hispanic (AOR = 1.51, CI = 1.02-2.24), completed high school only (AOR = 1.77, CI = 1.15-2.73), or lost a job during pregnancy (AOR = 2.62, CI = 1.39-4.93).
Modifiable risk factors and sociodemographic characteristics can impact maternal weight retention 24 months after pregnancy. Understanding postpartum weight retention is essential for guiding future public health research, programming, and policy. Tailoring appropriate public health interventions may help women sustain healthy weight during their reproductive years and beyond.
确定与产后 24 个月体重滞留相关的产妇特征。
数据来自 2016 年洛杉矶母婴（LAMB）随访调查，这是一项基于人群的前瞻性队列研究，评估了洛杉矶县产妇和婴儿的健康状况。2014 年，LAMB 最初对 6035 名产后 6 个月的女性进行了调查。2016 年 LAMB 随访在指数儿童满 2 岁后重新评估了同一队列。2679 名女性完成了 2016 年 LAMB 随访（调整后应答率为 52%）。在排除指数儿童后再次怀孕和产后体重信息缺失的受试者后，最终样本量为 1524 例。本分析纳入了 8 个预测因素：妊娠期体重增加、孕前 BMI、运动、产后情绪低落、年龄、种族、教育和孕期失业。使用 SAS 9.3 进行卡方检验和逻辑回归分析。
分娩后 2 年，体重滞留的女性比怀孕前平均多增重 15.3 磅。当女性超过妊娠期体重增加指南（AOR=2.03，95%CI=1.40-2.93）、不运动（AOR=3.32，CI=1.85-5.98）、年龄在 20-29 岁之间（AOR=1.54，CI=1.01-2.36）、为西班牙裔（AOR=1.51，CI=1.02-2.24）、仅完成高中学业（AOR=1.77，CI=1.15-2.73）或在孕期失业（AOR=2.62，CI=1.39-4.93）时，更有可能出现产后体重滞留。
可改变的危险因素和社会人口特征可能会影响产后 24 个月的产妇体重滞留。了解产后体重滞留对于指导未来的公共卫生研究、规划和政策至关重要。制定适当的公共卫生干预措施可能有助于女性在生殖期及以后保持健康的体重。
