To investigate the prevalence and factors associated with no intention to exclusively breastfeed for the first 6 months of life in a sample of women in the first 24 h postpartum during the hospital stay.
Cross-sectional study with data from screening phase of a birth cohort. The proportion of mothers who did not intend to breastfeed exclusively for 6 months (primary outcome) derived from a negative response to the question "Would you be willing to try to breastfeed exclusively for the first 6 months?", in an interview conducted by previously trained interviewers. Crude and adjusted prevalence ratios (PR) with 95% confidence intervals were obtained by Poisson regression with robust variance.
A total of 2964 postpartum women were interviewed. The overall prevalence of mothers who did not intend to breastfeed exclusively for 6 months was 17.8% (16.4-19.1%). After adjusting for maternal age and type of pregnancy (singleton or multiple), no intention to exclusively breastfeed was higher in mothers with a monthly household income < 3 minimum wages (PR, 1.64; 1.35-1.98) and in those who intended to smoke 4-7 days/week after delivery (PR, 1.42; 1.11-1.83). The presence of significant newborn morbidity (PR, 0.32; 0.19-0.54) and intention to breastfeed up to 12 months (PR, 0.46; 0.38-0.55) had a protective effect against not intending to breastfeed exclusively for 6 months.
Approximately 1 in every 5 mothers did not intend to breastfeed exclusively for 6 months. Strategies aimed at promoting exclusive breastfeeding should focus attention on mothers from lower economic strata and smokers.
在住院期间，对产后 24 小时内的妇女样本进行调查，了解她们在头 6 个月内完全不打算母乳喂养的流行情况及其相关因素。
这是一项横断面研究，数据来自于一个出生队列的筛查阶段。通过询问“你愿意尝试在前 6 个月内完全母乳喂养吗？”，对先前经过培训的访视员进行访谈，从母亲的回答中得出不打算完全母乳喂养 6 个月的比例（主要结局）。使用泊松回归和稳健方差获得未经调整和调整后的粗患病率比（PR）及其 95%置信区间。
共对 2964 名产后妇女进行了访谈。不打算完全母乳喂养 6 个月的母亲总体比例为 17.8%（16.4-19.1%）。调整母亲年龄和妊娠类型（单胎或多胎）后，月收入低于 3 个最低工资的母亲不打算完全母乳喂养的比例更高（PR，1.64；1.35-1.98），打算在分娩后 4-7 天/周吸烟的母亲也更高（PR，1.42；1.11-1.83）。新生儿有明显的发病率（PR，0.32；0.19-0.54）和打算母乳喂养至 12 个月（PR，0.46；0.38-0.55）的母亲不太可能不打算完全母乳喂养 6 个月。
大约每 5 位母亲中就有 1 位不打算完全母乳喂养 6 个月。旨在促进纯母乳喂养的策略应关注经济水平较低的母亲和吸烟者。
