目的探讨母乳喂养与婴儿社会性反应的关系。方法以2012年1—12月在安徽省马鞍山市妇幼保健院儿童保健门诊进行常规体检的3个月±7 d的1 943名婴儿作为研究对象建立队列并定期随访,采用社会性反应问卷定期评价其社会性反应,同时收集婴儿父母的人口统计学资料、围生期情况和每月龄母乳喂养情况等进行分析。结果控制人口统计学特征和围生期因素后,结果显示,在2、3、4、5月龄完全母乳喂养是婴儿社会性反应的促进因素,其OR值(95%CI)分别为1.384(1.086~1.765)、1.279(1.023~1.599)、1.361(1.023~1.599)、1.461(1.043~2.046);在5~11月龄部分母乳喂养的婴儿其社会性反应得分均高于人工喂养婴儿,其OR值(95%CI)分别为1.378(1.139~1.668)、1.297(1.086~1.551)、1.265(1.066~1.501)、1.225(1.036~1.447)、1.183(1.000~1.398)、1.214(1.021~1.442)、1.269(1.055~1.527)。结论完全母乳喂养持续2月以上或部分母乳喂养持续5月以上是婴儿社会性反应的积极促进因素。

Results After controlling for demographic characteristics and perinatal factors, the results showed that complete breastfeeding at 2, 3, 4, and 5 months of age was a contributing factor in the social response in infants with OR values (95% CI) of 1.384 1.086-1.765), 1.279 (1.023-1.599), 1.361 (1.023-1.599), and 1.461 (1.043-2.0446). The part-time breastfeeding infants aged 5 to 11 months had higher scores of social reaction than those of artificial feeding infants OR values (95% CI) were 1.378 (1.139-1.668), 1.297 (1.086-1.551), 1.265 (1.066-1.501), 1.225 (1.036-1.447), 1.183 (1.000-1.398), 1.214 (1.021-1.482) , 1.269 (1.055 ~ 1.527).
