This study aimed to identify factors associated with interruption of exclusive breastfeeding (EBF) in low birth weight infants receiving primary care. This was a cross-sectional study of 170 infants treated at primary care units on the urban periphery of São Paulo, Brazil. The sample included infants with birth weight ≤ 2,500g (including twins) and 5-minute Apgar ≥ 7, followed until the third month of life, and excluded infants/mothers with complications that would impede EBF, besides infant/maternal deaths. Data were collected from forms completed during consultations and patient records. Prevalence ratios were obtained by Poisson regression. The following factors were associated with interruption of EBF in the first three months of life: maternal age ≤ 18 years; informal employment (protective factor); alcohol intake during pregnancy; < 6 prenatal visits; multiple gestations; birth weight ≤ 2,000g; difficulty breastfeeding in the first month; complaints in breastfeeding during the first month; and use of pacifiers in the first two months. Prior knowledge of these factors can help plan measures and policies to increase EBF rates among low birth weight infants.
本研究旨在确定在接受初级保健的低体重婴儿中，与纯母乳喂养（EBF）中断相关的因素。这是一项针对巴西圣保罗市郊区初级保健单位治疗的170名婴儿的横断面研究。样本包括出生体重≤2500克（包括双胞胎）且5分钟阿氏评分≥7分的婴儿，随访至其生命的第三个月，排除有妨碍纯母乳喂养的并发症的婴儿/母亲以及婴儿/母亲死亡情况。数据从会诊期间填写的表格和患者记录中收集。通过泊松回归获得患病率比。以下因素与生命前三个月的纯母乳喂养中断相关：母亲年龄≤18岁；非正规就业（保护因素）；孕期饮酒；产前检查次数<6次；多胎妊娠；出生体重≤2000克；第一个月母乳喂养困难；第一个月母乳喂养时有不适；以及前两个月使用安抚奶嘴。了解这些因素有助于制定措施和政策，以提高低体重婴儿的纯母乳喂养率。
