To describe the characteristics of mothers and children and to evaluate the factors associated with discontinuation of exclusive breastfeeding.
A cross-sectional study on infants under six months of age who attended the vaccination campaign in 2008. In the sample design, vaccination units were selected by drawing lots and infants were similarly selected later at each unit systematically. A semi-structured instrument was used for data collection, containing questions about children's nutrition and socio-demographic characteristics. We used Odds Ratio and the χ² test for data analysis, accepting as the critical level p<0.05.
The prevalence of breastfeeding for infants under 120 and 180 days of age was 89.5 and 85% respectively, and exclusive breastfeeding was 50.6 and 39.7% for infants less than 120 and 180 days of age, respectively. The factors most related to the abandonment of exclusive breastfeeding in infants under six months were maternal employment outside the home (OR=2.73; 95%CI=1.74-4.29) and use of pacifiers (OR=4.26; 95%CI=2.85-6.38). The mother being multiparous (OR=0.57; 95%CI=0.40-0.81) and receiving postpartum care in the public health care network (OR=0.55; 95%CI=0.39-0.79) represented protective factors against the practice of early cessation of breastfeeding.
The prevalence of breastfeeding and exclusive breastfeeding in the municipality of Uberlândia is among the highest in the country and the factors most often associated with the practice of early weaning were maternal employment outside the home, offering pacifiers to the infants, receiving postpartum care in the private health sector, and primiparity.
描述母亲和儿童的特征，并评估与纯母乳喂养中断相关的因素。
对2008年参加疫苗接种活动的6个月以下婴儿进行横断面研究。在样本设计中，通过抽签选择疫苗接种单位，随后在每个单位系统地类似地选择婴儿。使用半结构化工具进行数据收集，其中包含有关儿童营养和社会人口学特征的问题。我们使用优势比和χ²检验进行数据分析，将临界水平p<0.05作为接受标准。
120日龄和180日龄以下婴儿的母乳喂养率分别为89.5%和85%，120日龄以下和180日龄以下婴儿的纯母乳喂养率分别为50.6%和39.7%。与6个月以下婴儿纯母乳喂养中断最相关的因素是母亲外出工作（优势比=2.73；95%置信区间=1.74-4.29）和使用安抚奶嘴（优势比=4.26；95%置信区间=2.85-6.38）。母亲多产（优势比=0.57；95%置信区间=0.40-0.81）和在公共卫生保健网络接受产后护理（优势比=0.55；95%置信区间=0.39-0.79）是预防早期停止母乳喂养的保护因素。
乌贝兰迪亚市的母乳喂养和纯母乳喂养率在该国处于最高水平，与早期断奶最常相关的因素是母亲外出工作、给婴儿使用安抚奶嘴、在私立卫生部门接受产后护理以及初产。
