Despite caregiver and policy support for breastfeeding, rates for initiating and duration of breastfeeding fell far short of Healthy People 2000 goals during the 1980s.
Data from the 1988 National Maternal-Infant Health Survey, collected from January 1989 through June 1991, were analyzed to examine predictors of duration of lactation for a sample of 2372 breastfeeding women. We conducted comparisons between women who fully breastfed and those who partially breastfed using logistic regression analysis.
Mothers were more likely to breastfeed for longer than six months if they fully breastfed during the first month postpartum, were nonsmokers, were of higher parity, were consistent in their prenatal intent to breastfeed fully or partially and in their postpartum behaviors, participated in childbirth education classes, and delayed their return to work postpartum.
In this study sample, although rates did not meet Healthy People 2000 goals for duration of breastfeeding, some predictors of duration were identified that can be affected by programmatic support or public policy. Our findings indicated that variables that are associated with breastfeeding and longer duration of the practice are typically correlated with social status. To support the development of breastfeeding as the cultural norm, interventions targeting breastfeeding outcomes should consider social status, ethnicity, and cultural factors.
尽管有照顾者和政策对母乳喂养的支持，但在20世纪80年代，母乳喂养的开始率和持续时间远未达到《2000年健康人群》的目标。
分析了1989年1月至1991年6月收集的1988年全国母婴健康调查的数据，以检查2372名母乳喂养女性样本的泌乳持续时间的预测因素。我们使用逻辑回归分析对完全母乳喂养的女性和部分母乳喂养的女性进行了比较。
如果母亲在产后第一个月进行完全母乳喂养、不吸烟、多产、产前完全或部分母乳喂养的意愿与产后行为一致、参加分娩教育课程并推迟产后重返工作岗位，她们更有可能母乳喂养超过六个月。
在本研究样本中，尽管母乳喂养持续时间未达到《2000年健康人群》的目标，但确定了一些泌乳持续时间的预测因素，这些因素可能会受到项目支持或公共政策的影响。我们的研究结果表明，与母乳喂养及其较长持续时间相关的变量通常与社会地位相关。为了支持将母乳喂养发展为文化规范，针对母乳喂养结果的干预措施应考虑社会地位、种族和文化因素。
