Breastfeeding is associated with health benefits for both the mother and infant and is therefore important to support; moreover, parental leave is a beneficial factor for breastfeeding. The Swedish parental leave is generous, allowing each parent to take 90 days; additionally, a further 300 days can be taken by either parent. Generally, mothers take 70% of the parental leave days, mainly during the first year. However, breastfeeding duration has declined in the last decade, and it is not known how shared parental leave is associated with the duration of breastfeeding.
To investigate how parental leave is associated with the duration of exclusive and partial breastfeeding of the infant during the first 12 months after birth. An additional aim was to describe infants' and parents' characteristics and mode of birth in association with the duration of exclusive and partial breastfeeding.
This cross-sectional study was part of the Swedish Pregnancy Planning Study, conducted in Sweden in 2012-2015. The parents were recruited at 153 antenatal clinics in nine counties. In total, 813 couples completed a follow-up questionnaire 1 year after birth. Linear regression models were used to analyse the association between parental leave and the duration of breastfeeding.
Infants were exclusively breastfed for, on average, 2.5 months (range 0-12 months) and partially breastfed, on average, 7 months (range 0-12 months). Most of the parental leave was taken by the mother (mean = 10.9 months) during the infant's first 12 months, while the partner took 3 months, on average. The parental leave (used and planned) during the infant's first 24 months were, on average, 21 months. In the multivariate linear regression analysis, mothers' and partners' high level of education (p < 0.001, p = 0.044, respectively), mothers' higher age (p = 0.049), non-instrumental vaginal birth (p = 0.004) and longer parental leave for the first 24 months (p < 0.001) were associated with longer duration of partial breastfeeding.
The duration of partial breastfeeding was associated with higher parental educational level, higher age, non-instrumental vaginal birth and longer parental leave.
母乳喂养对母婴健康都有好处，因此需要加以支持；此外，父母假是母乳喂养的一个有益因素。瑞典的父母假很慷慨，允许每位父母休 90 天；此外，父母中任何一方还可以再休 300 天。通常，母亲会休 70%的父母假，主要是在孩子出生的第一年。然而，在过去的十年中，母乳喂养的持续时间有所下降，目前尚不清楚共享父母假与母乳喂养持续时间有何关联。
调查父母假如何与婴儿出生后 12 个月内的纯母乳喂养和部分母乳喂养持续时间相关。另一个目的是描述婴儿和父母的特征以及分娩方式与纯母乳喂养和部分母乳喂养持续时间的关系。
这是一项在瑞典于 2012-2015 年进行的瑞典妊娠计划研究中的横断面研究。在 9 个郡的 153 个产前诊所招募了父母。共有 813 对夫妇在孩子出生 1 年后完成了随访问卷。线性回归模型用于分析父母假与母乳喂养持续时间之间的关联。
婴儿平均纯母乳喂养 2.5 个月（0-12 个月），部分母乳喂养 7 个月（0-12 个月）。在婴儿出生后的 12 个月中，母亲主要休（平均 10.9 个月）了大部分父母假，而伴侣平均休了 3 个月。婴儿出生后的前 24 个月内，父母总共休了 21 个月的假。在多变量线性回归分析中，母亲和伴侣的高教育水平（p<0.001，p=0.044）、母亲年龄较高（p=0.049）、非器械性阴道分娩（p=0.004）和较长的前 24 个月父母假（p<0.001）与部分母乳喂养持续时间较长相关。
部分母乳喂养的持续时间与父母较高的教育水平、较高的年龄、非器械性阴道分娩和较长的父母假有关。
