Despite the benefits of breastfeeding, rates in the United States are low. Shorter maternity leave is associated with lower initiation and shorter durations of breastfeeding; however, little is known about how paid maternity leave may influence breastfeeding rates.
We used data from the 2006-2010 U.S. National Survey of Family Growth on the most recent birth to employed women who delivered a child within the previous 5 years. Separate multivariable logistic regression models were used to describe the associations between paid leave duration (0, 1-5, 6-11, ≥ 12 weeks, maternity leave not taken) and three outcomes: 1) breastfeeding initiation, 2) 6-month duration, and 3) 6-month duration among initiators.
Twenty-eight percent of prenatally employed women received no paid leave. Women who received 12 or more weeks of paid leave were more likely to initiate breastfeeding compared to women with no paid leave (87.3% vs 66.7%, adjusted odds ratio [aOR] 2.83 [95% confidence interval {CI} 1.23-6.48]). Similarly, women with 12 or more weeks of paid leave were more likely to breastfeed at 6 months, compared to women with no paid leave (24.9% vs 50.1%, aOR 2.26 [95% CI 1.20-4.26]). Among women who initiated breastfeeding, having received 12 or more weeks' paid leave increased the odds of breastfeeding for 6 or more months; however, the association was not statistically significant in the adjusted model (aOR 1.81 [95% CI 0.93-3.52]).
Employed women who received 12 or more weeks of paid maternity leave were more likely to initiate breastfeeding and be breastfeeding their child at 6 months than those without paid leave.
尽管母乳喂养有诸多益处,但美国的母乳喂养率较低。产假较短与较低的母乳喂养起始率及较短的母乳喂养持续时间相关;然而,关于带薪产假如何影响母乳喂养率,人们了解甚少。
我们使用了2006 - 2010年美国全国家庭成长调查的数据,这些数据来自过去5年内生育孩子的在职女性的最近一次分娩情况。采用单独的多变量逻辑回归模型来描述带薪休假时长(0周、1 - 5周、6 - 11周、≥12周、未休产假)与三个结果之间的关联:1)母乳喂养起始情况;2)6个月的母乳喂养持续时间;3)开始母乳喂养的女性中6个月的母乳喂养持续时间。
28%的产前在职女性未获得带薪休假。与未获得带薪休假的女性相比,获得12周或更长时间带薪休假的女性更有可能开始母乳喂养(87.3%对66.7%,调整后的优势比[aOR]为2.83[95%置信区间{CI}为1.23 - 6.48])。同样,与未获得带薪休假的女性相比,获得12周或更长时间带薪休假的女性在6个月时更有可能进行母乳喂养(24.9%对50.1%,aOR为2.26[95%CI为1.20 - 4.26])。在开始母乳喂养的女性中,获得12周或更长时间带薪休假会增加母乳喂养6个月或更长时间的几率;然而,在调整后的模型中该关联无统计学意义(aOR为1.81[95%CI为0.93 - 3.52])。
与未获得带薪休假的在职女性相比,获得12周或更长时间带薪产假的在职女性更有可能开始母乳喂养并在6个月时仍进行母乳喂养。
