Breastfeeding promotion is one of the most effective strategies to prevent child malnutrition; it reduces costs to families, health services and society. In Colombia, exclusive breastfeeding is practiced only by 10% of women.
To identify factors associated with the duration of exclusive breastfeeding.
A cohort of 438 primiparous women was followed during 6 months by means of 8 home interviews, in order to determine the duration of exclusive breastfeeding. Individual, family and health service factors were studied; and survival analysis was carried out.
At 8 days, only a few more than half of the participants maintained exclusive breastfeeding; at month 6 of follow-up, this proportion was reduced to 1.4%. The duration of exclusive breastfeeding was determined by: initiation of breastfeeding in the first 4 hours after delivery (HR= 4.07, 95% CI: 0.96-16.67), self-perceived sureness for breastfeeding (HR= 1.28, 95% CI: 1.04 -1.58), positive opinion of the baby's father regarding breastfeeding (HR= 1.26, 95% CI: 1.01-1.57), and newborn weight (HR= 1.23, 95% CI: 1.00-1.53).
There are factors before delivery and in the immediate puerperium that determine, partially, the duration of exclusive breastfeeding.
促进母乳喂养是预防儿童营养不良最有效的策略之一；它降低了家庭、卫生服务机构和社会的成本。在哥伦比亚，只有10%的女性进行纯母乳喂养。
确定与纯母乳喂养持续时间相关的因素。
对438名初产妇进行为期6个月的队列研究，通过8次家访来确定纯母乳喂养的持续时间。研究了个人、家庭和卫生服务机构等因素，并进行了生存分析。
在第8天时，只有略超过一半的参与者坚持纯母乳喂养；在随访的第6个月时，这一比例降至1.4%。纯母乳喂养的持续时间取决于以下因素：产后4小时内开始母乳喂养（风险比=4.07，95%置信区间：0.96-16.67）、自我感知的母乳喂养信心（风险比=1.28，95%置信区间：1.04-1.58）、婴儿父亲对母乳喂养的积极看法（风险比=1.26，95%置信区间：1.01-1.57）以及新生儿体重（风险比=1.23，95%置信区间：1.00-1.53）。
分娩前和产褥早期存在一些因素，这些因素部分决定了纯母乳喂养的持续时间。
