Exclusive breastfeeding (EBF) has multiple benefits for both the child and the mother; however, there is little data regarding the reason why Mexican mothers with a high socio-economic level abandon EBF before 6 months, and there is limited information about the practice of breastfeeding in private hospitals. The objective was to identify the factors associated with the cessation of exclusive breastfeeding in Mexican mothers at two private hospitals. A cross-sectional study was conducted with 218 upper-class mothers selected according to their place of residence by geographic location, socio-economic level, and pediatric consultations cost. They were over 18 years old and with children aged 6 to 24 months. Data were collected between July and November 2016 by face to face interview using a structured questionnaire while the mothers waited for the pediatric postnatal care consultation in two private hospitals in northeastern Mexico. Exclusive breastfeeding was measured according to World Health Organization (WHO) recommendations, which consist of providing only breast milk for the first 6 months of life. Chi-squared tests and multivariate logistic regression were performed. Mean maternal age was 31.4 years (SD of 4.4) and most of the participants had an undergraduate education, were married, and worked outside the home. The prevalence of exclusive breastfeeding at 6 months was 28%. Upper-class working mothers are less likely to continue breastfeeding. There was a negative association with employment (AOR 13.69; 95% CI 1.59, 111.11), bottle use in the first 6 months (AOR 7.93; 95% CI 3.07, 20.48), and a low level of knowledge (AOR 2.18; 95% CI 1.04, 4.56). After 6 months, only 61 mothers (28%) maintained exclusive breastfeeding. Knowledge level, bottle use, and employment are associated with premature cessation of EBF in Mexican upper-class mothers, attending two private hospitals. There was a high percentage of breastfeeding cessation in the sample. It is necessary to reinforce a strategy that coordinates the action of the different laws, regulations and programs affecting the exclusive breastfeeding practice, in order to adequately promote breastfeeding and support mothers in both public and private sectors.

在两家私立医院与墨西哥母亲放弃纯母乳喂养相关的因素。

纯母乳喂养 (EBF) 对孩子和母亲都有多重好处；然而，关于社会经济水平较高的墨西哥母亲在 6 个月前放弃 EBF 的原因的数据很少，关于私立医院母乳喂养实践的信息有限。目的是确定与两家私立医院的墨西哥母亲停止纯母乳喂养相关的因素。一项横断面研究对 218 名上流社会的母亲根据居住地的地理位置、社会经济水平和儿科咨询费用进行了选择。他们年满 18 岁，有 6 至 24 个月大的孩子。数据是在 2016 年 7 月至 11 月期间使用结构化问卷通过面对面访谈收集的，同时母亲们在墨西哥东北部的两家私立医院等待儿科产后护理咨询。纯母乳喂养是根据世界卫生组织 (WHO) 的建议衡量的，该建议包括在生命的前 6 个月仅提供母乳。进行卡方检验和多元逻辑回归。平均产妇年龄为 31.4 岁（SD 为 4.4），大多数参与者都接受过本科教育，已婚，并在外工作。6 个月时纯母乳喂养的流行率为 28%。上层阶级的职业母亲不太可能继续母乳喂养。与就业呈负相关（AOR 13.69；95% CI 1.59, 111.11），前 6 个月使用奶瓶（AOR 7.93；95% CI 3.07, 20.48），知识水平低（AOR 2.18；95% CI 1.04, 4.56）。6 个月后，只有 61 位母亲 (28%) 保持纯母乳喂养。知识水平、奶瓶使用和就业与就诊于两家私立医院的墨西哥上流社会母亲的 EBF 过早停止有关。样本中停止母乳喂养的比例很高。有必要加强一项战略，协调影响纯母乳喂养实践的不同法律、法规和计划的行动，以便在公共和私营部门充分促进母乳喂养和支持母亲。只有 61 位母亲（28%）坚持纯母乳喂养。知识水平、奶瓶使用和就业与就诊于两家私立医院的墨西哥上流社会母亲的 EBF 过早停止有关。样本中停止母乳喂养的比例很高。有必要加强一项战略，协调影响纯母乳喂养实践的不同法律、法规和计划的行动，以便在公共和私营部门充分促进母乳喂养和支持母亲。只有 61 位母亲（28%）坚持纯母乳喂养。知识水平、奶瓶使用和就业与就诊于两家私立医院的墨西哥上流社会母亲的 EBF 过早停止有关。样本中停止母乳喂养的比例很高。有必要加强一项战略，协调影响纯母乳喂养实践的不同法律、法规和计划的行动，以便在公共和私营部门充分促进母乳喂养和支持母亲。
