Often, efforts to improve overall population health require identifying and targeting programs to specific high-risk populations. Breastfeeding is an example. In order to determine initiation and duration rates among various groups in the City of Toronto, a random sample of 434 mothers with infants at four months of age was surveyed to determine the prevalence of breastfeeding and major impacts on its duration. The study found that, overall, 83% of mothers initiated breastfeeding at birth. The greatest rate of decline occurred during the first month. At four months postpartum, 57% of mothers continued to breastfeed, including 35% who were exclusively breastfeeding and 22% who were supplementing breast milk with formula. Breastfeeding duration was related to a number of factors, including information and support, parity, education, use of formula supplements and country of birth. Specific groups are identified for targeted programs, and a number of strategies are proposed.
通常，改善总体人群健康的努力需要确定特定的高危人群并针对他们开展项目。母乳喂养就是一个例子。为了确定多伦多市不同群体的母乳喂养起始率和持续率，对434名有四个月大婴儿的母亲进行了随机抽样调查，以确定母乳喂养的普及率及其持续时间的主要影响因素。研究发现，总体而言，83%的母亲在婴儿出生时开始母乳喂养。下降率最高的时期是在第一个月。产后四个月时，57%的母亲仍在继续母乳喂养，其中35%是纯母乳喂养，22%是用配方奶补充母乳喂养。母乳喂养的持续时间与多种因素有关，包括信息和支持、产次、教育程度、配方奶补充剂的使用以及出生国家。确定了特定群体以开展针对性项目，并提出了一些策略。
