To identify socio-cultural, obstetric and perinatal characteristics associated with complete breastfeeding (CBF) during the first 4 months of age, depending on maternal origin.
Socio-cultural, obstetric and perinatal aspects associated with breastfeeding depending on maternal origin were evaluated in a longitudinal study in a representative infant population from Aragon (n = 1452).
The prevalence of CBF was higher in immigrant mothers than in those from Spain. CBF was maintained in 37.2% of mothers from Spain at 4 months, compared with 43% of immigrants (P=.039) (RR Spanish/immigrants=0.76; 95% CI: 0.58-0.99); at 6 months this occurred in 13.9% vs. 23.8%, respectively (P<.001) (RR Spanish/immigrants=0.52; 95% CI: 0.37-0.72). The factors associated with CBF at 4 months are different between both groups. Mothers born in Spain are older (P=.002), have higher academic level (P=.001), greater parity (P=.003), and a higher probability of vaginal delivery (P=.005); and their children have the highest anthropometric values at birth. However, in immigrant mothers, the maintenance of CBF was associated with a higher maternal body mass index and with working at home. In both groups, CBF remains more frequently in those mothers who do not smoke (P=.001).
The prevalence of CBF during the first months of life is higher in immigrant mothers than in those from Spain, and socio-cultural, obstetric and perinatal factors are different, depending on maternal origin.
根据母亲的籍贯，确定与4个月龄内纯母乳喂养（CBF）相关的社会文化、产科和围产期特征。
在一项针对阿拉贡地区具有代表性的婴儿群体（n = 1452）的纵向研究中，评估了根据母亲籍贯划分的与母乳喂养相关的社会文化
、产科和围产期方面的情况。
移民母亲的纯母乳喂养率高于西班牙母亲。4个月时，西班牙母亲中37.2%保持纯母乳喂养，而移民母亲为43%（P = 0.039）（西班牙/移民相对危险度=0.76；95%可信区间：0.58 - 0.99）；6个月时，这一比例分别为13.9%和23.8%（P<0.001）（西班牙/移民相对危险度=0.52；95%可信区间：0.37 - 0.72）。两组在4个月时与纯母乳喂养相关的因素有所不同。出生在西班牙的母亲年龄更大（P = 0.002）、学历更高（P = 0.001）、产次更多（P = 0.003），阴道分娩概率更高（P = 0.005）；并且她们的孩子出生时人体测量值最高。然而，在移民母亲中，纯母乳喂养的维持与较高的母亲体重指数以及在家工作有关。在两组中，不吸烟的母亲更常保持纯母乳喂养（P = 0.001）。
移民母亲在生命最初几个月的纯母乳喂养率高于西班牙母亲，并且根据母亲籍贯不同，社会文化、产科和围产期因素也有所不同。
