The use of oral contraceptive before pregnancy and breastfeeding duration: A cross-sectional study with retrospective ascertainment

Abstract Background 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. Aim 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. Methods 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. Results 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. Conclusion The duration of partial breastfeeding was associated with higher parental educational level, higher age, non-instrumental vaginal birth and longer parental leave.

Abstract Background The effect of joint health on quality of life in middle-aged and older women is becoming more widely recognized with the aging of the world’s population. However, the association of long-term breastfeeding with joint pain and knee osteoarthritis has not been fully examined. The aim of this study was to determine the association of long-term breastfeeding with joint pain and knee osteoarthritis in middle-aged Korean women. Methods A cross-sectional study was conducted among 3,454 women aged ≥50 years who underwent knee radiography and answered a questionnaire on breastfeeding and joint pain for the 5 th Korean National Health and Nutrition Examination Survey (2010–2011). After adjusting for confounding sociodemographic, medical history, and obstetric and gynecologic variables, logistic regression analysis was conducted to analyze the incidence of joint pain and knee osteoarthritis according to breastfeeding and its duration. Among the 3,454 participants, 298 had not breastfed and 1,042, 815, and 1,299 had breastfed for 1–24, 25–48, and ≥49 months, respectively. Of all participants, 1,731 had joint pain and 739 were diagnosed with knee osteoarthritis after radiography. Results The odds ratio (OR) for joint pain among women who breastfed was 1.493 times higher than that among women who did not (p=0.044). As breastfeeding duration increased, the OR of joint pain incidence also increased (p for trend; p=0.002). For knee osteoarthritis, the OR was significantly different between the 25–48 and ≥49 months groups (2.299 [p=0.03] and 2.166 [p=0.047], respectively). Reanalysis after selecting only participants aged ≥60 years showed that the prevalence of joint pain and knee osteoarthritis was more positively correlated with extended breastfeeding duration (joint pain, p for trend; p=0.005) (knee osteoarthritis, p for trend; p=0.012). Conclusions Long-term feeding of more than 25 months was associated with an increased prevalence of arthralgia and degenerative arthritis after menopause in Korean elderly women.

Abstract Background The effect of joint health on the quality of life of middle-aged and older women is becoming more widely recognized with the aging of the world’s population. However, the association of long-term breastfeeding with joint pain and knee osteoarthritis has not been fully examined. The aim of this study was to determine the association of prior breastfeeding duration with current joint pain and knee osteoarthritis in middle-aged Korean women. Methods This cross-sectional study was conducted among 3,454 women aged ≥50 years who underwent knee radiography and answered a questionnaire on breastfeeding and joint pain for the 5th Korea National Health and Nutrition Examination Survey (2010–2011). After adjusting for confounding sociodemographic, medical history, and obstetric and gynecologic variables, logistic regression analysis was conducted to analyze the prevalence of joint pain and knee osteoarthritis according to breastfeeding and its duration. Results Among the 3,454 participants, 298 had not breastfed and 1,042, 815, and 1,299 had breastfed for 1–24, 25–48, and ≥49 months, respectively. Of all participants, 1,731 had joint pain and 739 were diagnosed with knee osteoarthritis after radiography.Using the non-breastfeeding group as a reference, the odds ratio (OR) for joint pain among women who breastfed ≥1 month was 1.49 (95% confidence interval [CI] 1.01-2.21). As the breastfeeding duration increased, the OR of joint pain prevalence also increased (p for trend; p=0.002). For knee osteoarthritis, the OR was 2.30 in the 25–48 months group (95% CI 1.09-4.86). The OR of knee osteoarthritis in the ≥49 months group was 2.17 (95% CI 1.01-4.64). Sensitivity analysis after selecting only participants aged ≥60 years showed that the prevalence of joint pain and knee osteoarthritis was more positively correlated with extended breastfeeding duration (joint pain, p for trend; p=0.005) (knee osteoarthritis, p for trend; p=0.012).Conclusions Long-term feeding for more than 25 months was associated with an increased prevalence of joint pain and degenerative arthritis in Korean women aged ≥50 years.
