The objective of this study was to evaluate the association between breastfeeding duration and child neurodevelopment based on the Polish Mother and Child Cohort Study.
The current analysis included 501 mother-child pairs. The analysis evaluating the association between the length of breastfeeding and child neurodevelopment considered the following variables: maternal age and body mass index, weight gain during pregnancy, parental level of education, marital status, socioeconomic status, child gender, birthweight, type of delivery, preterm delivery, pre- and postnatal exposure to tobacco constituents and child day care attendance. Psychomotor development was assessed in 1-year-olds on the .
The length of breastfeeding correlated positively with maternal age at delivery (ρ = 0.13), maternal and paternal level of education (ρ = 0.2 and ρ = 0.14 respectively), birthweight (ρ = 0.1) and marital status (ρ = 0.16) (p < 0.05). A negative correlation between the length of breastfeeding and maternal smoking status during the first year after delivery (ρ = -0.19) and weight gain during pregnancy (r = -0.1) was observed (p < 0.05). The association between the duration of breastfeeding and child development was not statistically significant in the model with the inclusion of confounding variables. A significant association between language development and maternal level of education (p = 0.004), gender of the child (p = 0.0007) and maternal weight gain during pregnancy (p = 0.01) was found. A negative association between cognitive development and maternal salivary cotinine during pregnancy (p = 0.03) and a negative association between motor development and maternal smoking status during the first year after delivery (p = 0.007) were also found.
This study found no significant association between the duration of breastfeeding and child development after adjustment for confounders. Int J Occup Med Environ Health. 2019;32(2):175-84.
本研究的目的是基于波兰母婴队列研究评估母乳喂养持续时间与儿童神经发育之间的关联。
当前分析纳入了501对母婴对。评估母乳喂养时长与儿童神经发育之间关联的分析考虑了以下变量：母亲年龄和体重指数、孕期体重增加、父母教育水平、婚姻状况、社会经济地位、儿童性别、出生体重、分娩类型、早产、产前和产后接触烟草成分以及儿童日托情况。对1岁儿童进行了心理运动发育评估。
母乳喂养持续时间与分娩时母亲年龄（ρ = 0.13）、母亲和父亲的教育水平（分别为ρ = 0.2和ρ = 0.14）、出生体重（ρ = 0.1）和婚姻状况（ρ = 0.十六）呈正相关（p < 0.05）。观察到母乳喂养持续时间与产后第一年母亲吸烟状况（ρ = -0.19）和孕期体重增加（r = -0.1）之间呈负相关（p < 0.05）。在纳入混杂变量的模型中，母乳喂养持续时间与儿童发育之间的关联无统计学意义。发现语言发育与母亲教育水平（p = 0.004）、儿童性别（p = 0.0007）和母亲孕期体重增加（p = 0.01）之间存在显著关联。还发现认知发育与孕期母亲唾液可替宁之间呈负相关（p = 0.03），运动发育与产后第一年母亲吸烟状况之间呈负相关（p = 0.007）。
本研究发现，在对混杂因素进行调整后，母乳喂养持续时间与儿童发育之间无显著关联。《国际职业医学与环境卫生杂志》。2019年；32(二):175 - 84。
