To examine associations of workplace leave length with breastfeeding initiation and continuation at 1, 2, and 3 months. We analyzed 2016 to 2018 data for 10 sites in the United States from the Pregnancy Risk Assessment Monitoring System, a site-specific, population-based surveillance system that samples women with a recent live birth 2 to 6 months after birth. Using multivariable logistic regression, we examined associations of leave length (< 3 vs ≥ 3 months) with breastfeeding outcomes. Among 12 301 postpartum women who planned to or had returned to the job they had during pregnancy, 42.1% reported taking unpaid leave, 37.5% reported paid leave, 18.2% reported both unpaid and paid leave, and 2.2% reported no leave. Approximately two thirds (66.2%) of women reported taking less than 3 months of leave. Although 91.2% of women initiated breastfeeding, 81.2%, 72.1%, and 65.3% of women continued breastfeeding at 1, 2, and 3 months, respectively. Shorter leave length (< 3 months), whether paid or unpaid, was associated with lower prevalence of breastfeeding at 2 and 3 months compared with 3 or more months of leave. Women with less than 3 months of leave reported shorter breastfeeding duration than did women with 3 or more months of leave. (. 2021;111(11):2036-2045. https://doi.org/10.2105/AJPH.2021.306484).
探讨工作假期长度与产后 1、2 和 3 个月时开始和持续母乳喂养的关联。
我们分析了美国 10 个地点 2016 年至 2018 年期间妊娠风险评估监测系统的数据，该系统是一个特定地点的、基于人群的监测系统，对最近分娩后 2 至 6 个月的妇女进行抽样。我们采用多变量逻辑回归，分析了假期长度（＜3 个月与≥3 个月）与母乳喂养结局的关联。在 12301 名计划或已返回妊娠期间工作的产后妇女中，42.1%报告休无薪假，37.5%报告休带薪假，18.2%报告休无薪和带薪假，2.2%报告无休假。大约三分之二（66.2%）的妇女报告休假时间少于 3 个月。尽管 91.2%的妇女开始母乳喂养，但分别有 81.2%、72.1%和 65.3%的妇女在产后 1、2 和 3 个月时持续母乳喂养。与休假 3 个月或以上相比，较短的休假长度（＜3 个月），无论是带薪还是无薪，与产后 2 和 3 个月时母乳喂养率较低相关。与休假 3 个月或以上的妇女相比，休假少于 3 个月的妇女报告母乳喂养持续时间更短。（Am J Public Health. 2021;111(11):2036-2045. https://doi.org/10.2105/AJPH.2021.306484）。
