The Women, Infants, and Children (WIC) branch of the Hawaii Department of Health encourages and assists mothers in breastfeeding. A study was done to determine whether an electric breast pump (vs. a manual pump) would increase breastfeeding duration in those returning to work or school full-time.
During 2002-2003, a randomized trial was conducted among 280 women, with the duration of breastfeeding analyzed in 229 of these women. Descriptive analyses and a multivariate logistic regression analysis assessed factors associated with breastfeeding at 6 months. Unadjusted and adjusted survival analyses were performed to estimate the duration of breastfeeding.
In all, 76.8% of women using the manual breast pump and 72.3% of those using the electric breast pump breastfed for at least 6 months. This difference did not reach statistical significance. In the survival analysis adjusted for pump assignment, maternal age, race/ethnicity, marital status, and parity, women with at least some college education breastfed for a 38% shorter time than women with a high school or lower education.
Our findings suggest that the manual breast pump may work as well as the electric breast pump when breastfeeding is encouraged and supported among women returning to work or school full-time. Particular attention should be given to examining reasons why women with greater education breastfed for a shorter duration. Further research is needed to validate these results to better inform breastfeeding women returning to work or school.
夏威夷卫生部的妇女、婴儿与儿童（WIC）部门鼓励并协助母亲进行母乳喂养。开展了一项研究，以确定电动吸奶器（与手动吸奶器相比）是否会增加那些全职重返工作岗位或学校的女性的母乳喂养时长。
在2002年至2003年期间，对280名女性进行了一项随机试验，其中229名女性的母乳喂养时长进行了分析。描述性分析和多变量逻辑回归分析评估了与6个月时母乳喂养相关的因素。进行了未调整和调整后的生存分析，以估计母乳喂养的时长。
总体而言，使用手动吸奶器的女性中有76.8%、使用电动吸奶器的女性中有72.3%进行母乳喂养至少6个月。这种差异未达到统计学显著性。在根据吸奶器分配、产妇年龄、种族/族裔、婚姻状况和胎次进行调整的生存分析中，至少接受过一些大学教育的女性母乳喂养的时间比高中及以下学历的女性短38%。
我们的研究结果表明，在全职重返工作岗位或学校的女性中，当鼓励并支持母乳喂养时，手动吸奶器的效果可能与电动吸奶器一样好。应特别关注研究受教育程度较高的女性母乳喂养时间较短的原因。需要进一步研究以验证这些结果，以便为重返工作岗位或学校的母乳喂养女性提供更好的信息。
