To study the current prevalence of breastfeeding (BF) in Aragon (Spain) during the first 12 months of life, and analyse its demographic, perinatal and social influential factors.
Obstetric, perinatal and feeding aspects were evaluated in a longitudinal and observational study, in a representative cohort of infant population from Aragon born between March 2009 to March 2010, controlled until 12 months of age (N=1.602).
Exclusive or predominant BF was more frequent than the rest of feeding modalities during the first 4 months of life. Maintenance prevalence of any BF modality was 82.5% at 1(st) month of age, 71.8% at 3(rd), 54.3% at 6(th), and 27.8% at 12 months of age. Maternal variables that were significantly associated with BF maintenance both at 1 and 6 months of age were: delivery modality (higher probability in case of vaginal delivery), academic level (higher probability if university studies), origin (higher probability in mothers from Africa), adiposity (higher probability of normal weight or overweight mothers compared with obese ones), and not to smoke during gestation.
BF prevalence in Aragon (Spain) during the first 12 months of age is high and has increased compared with previous data. BF continues in more than half of infants at six months and in a quarter of infants at 12 months of age. Maternal factors that significantly influence BF initiation and maintenance are, delivery modality, academic level, origin (immigration), adiposity and smoking habit.
研究西班牙阿拉贡地区婴儿出生后前12个月母乳喂养的当前流行情况，并分析其人口统计学、围产期及社会影响因素。
在一项纵向观察性研究中，对2009年3月至2010年3月在阿拉贡出生的具有代表性的婴儿队列的产科、围产期及喂养情况进行评估，随访至12个月龄（N = 1602）。
在出生后的前4个月，纯母乳喂养或主要母乳喂养比其他喂养方式更为常见。任何母乳喂养方式在1月龄时的维持率为82.5%，3月龄时为71.8%，6月龄时为54.3%，12月龄时为27.8%。在1月龄和6月龄时与母乳喂养维持显著相关的母亲变量包括：分娩方式（顺产概率更高）、学历水平（大学学历概率更高）、出生地（非洲母亲概率更高）、肥胖程度（正常体重或超重母亲比肥胖母亲概率更高）以及孕期不吸烟。
西班牙阿拉贡地区婴儿出生后前12个月母乳喂养的流行率较高，与之前的数据相比有所增加。超过一半的婴儿在6个月时仍在进行母乳喂养，四分之一的婴儿在12个月时仍在进行母乳喂养。对母乳喂养开始及维持有显著影响的母亲因素包括分娩方式、学历水平、出生地（移民情况）、肥胖程度及吸烟习惯。
