The objective of this cross-sectional and quantitative study was to identify the prevalence and determinants of exclusive breastfeeding among infants less than six months of age in the city of Serrana, Sao Paulo, Brazil in 2009. A validated semi-structured questionnaire was administered to the guardians of the children less than six months of age who attended the second phase of a Brazilian vaccination campaign against polio. Univariate and multivariate analysis presented in odds ratios and confidence intervals was accomplished. Of the total of 275 infant participants, only 29.8% were exclusively breastfed. Univariate analysis revealed that mothers who work outside the home without maternity leave, mothers who did not work outside the home, adolescent mothers, and the use of pacifiers have a greater chance of interrupting exclusive breastfeeding. In the multivariate analysis, mothers who work outside the home without maternity leave are three times more likely to wean their children early. Results provide suggestions for the redirection and planning of interventions targeting breastfeeding.
这项横断面定量研究的目的是确定2009年巴西圣保罗塞拉纳市6个月以下婴儿纯母乳喂养的患病率及其决定因素。对参加巴西第二轮脊髓灰质炎疫苗接种运动的6个月以下儿童的监护人进行了一份经过验证的半结构化问卷调查。采用比值比和置信区间进行单因素和多因素分析。在总共275名婴儿参与者中，只有29.8%是纯母乳喂养。单因素分析显示，没有产假却外出工作的母亲、不外出工作的母亲、青少年母亲以及使用安抚奶嘴的母亲更有可能中断纯母乳喂养。在多因素分析中，没有产假却外出工作的母亲使孩子过早断奶的可能性高出三倍。研究结果为针对母乳喂养的干预措施的调整和规划提供了建议。
