Longer shared parental leave is associated with longer duration of breastfeeding: a cross-sectional study among Swedish mothers and their partners

BackgroundBreastfeeding 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.AimTo 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.MethodsThis 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.ResultsInfants 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.ConclusionThe duration of partial breastfeeding was associated with higher parental educational level, higher age, non-instrumental vaginal birth and longer parental leave.

Breast size increment during pregnancy and breastfeeding in mothers with polycystic ovary syndrome: a follow‐up study of a randomised controlled trial on metformin versus placebo

To study the significance of breast size increment in pregnancy, and the impact of metformin during pregnancy on breastfeeding in women with polycystic ovary syndrome (PCOS). A follow-up study of a randomised controlled trial (the PregMet study). Eleven secondary care centres. Women with PCOS during pregnancy and postpartum. Women with PCOS were randomised to treatment with metformin or placebo from the first trimester to delivery. Questionnaires were sent to 240 participants 1 year postpartum: 186 responded. Pre-pregnancy and late-pregnancy brassiere size and breastfeeding patterns were registered, and androgen levels were measured in the mothers. No difference in breast size increment and breastfeeding were found between the placebo and metformin groups. Breast size increment correlated positively with the duration of both exclusive and partial breastfeeding, whereas body mass index (BMI) correlated negatively with the duration of partial breastfeeding. Dehydroepiandrostenedione-sulphate (DHEAS), testosterone and free testosterone index (FTI) in pregnancy did not correlate with breast size increment or duration of breastfeeding. Women with no change in breast size were more obese, had higher blood pressure, serum triglycerides and fasting insulin levels, and had a shorter duration of breastfeeding compared with those with breast size increment. Metformin and androgens had no impact on breastfeeding. Women with PCOS who had no breast size increment in pregnancy seem to be more metabolically disturbed and less able to breastfeed.

Momentos críticos de abandono de la lactancia materna en un seguimiento de 6 meses

ObjectiveTo identify critical moments for discontinuing full breast feeding (FBF) and any breast feeding (BF) in the first 6 months. MethodWe performed an observational, 6-month follow-up study of an accidental sample of 270 mothers with healthy breastfed infants. Survival analyses and the incidence rates (IR) of discontinuance of FBF and ABF every fortnight were obtained. ResultsLoss to follow-up: 10% at 4 months and 17% at 6 months. The median length of FBF was 120 days (95% CI=111.17-128.83) and the median length of BF was 171 days (95% CI =151.40-190.60). The median duration of partial breast feeding (PBF) was 30 days (95% CI=19.49-40.51). IR peaks of BF were found in the first and second weeks and after week 17. Increases of the IR of BF coincided with IR peaks of FBF and also included subsequent weeks. ConclusionsThe highest IR for discontinuance of BF were found at hospital discharge and return to work. PBF was related to weaning. These results suggest the need to increase support after discharge, especially to mothers PBF and those returning to work.
