Evaluation of Oxidative Stress, Antioxidant Power, and Antioxidant Potential of Breastmilk of Breast-Feeding Mothers
Abstract: Purpose: The purpose of this study was to evaluate oxidative stress, antioxidant power, and antioxidant potential of breastmilk of breast-feeding mothers from the early postpartum period to the first 3 months postpartum, and to examine the dynamics and the relationships among them. Method: For 47 pu-erperant women who gave vaginal birth without any pregnancy complications, the oxidative stress levels (d-ROMs levels) and antioxidant power (BAP levels) in the maternal plasma as well as antioxidant potential of breastmilk (BAP levels in breastmilk) were measured 3 times, i.e., in the early puerperium (4 or 5 days after giving birth), one month after giving birth, and 3 months after giving birth. Results: The d-ROMs levels in the maternal plasma were significantly high in the early puerperium (p < 0.001), and decreased gradually in the post-partum period (p < 0.001). On the other hand, BAP levels were significantly low in the early puerperium (p < 0.001), and increased to the almost normal level during one month after giving birth. BAP levels in breastmilk were significantly high in the early puerperium compared with the other periods (p < 0.001), and decreased gradually until 3 months after giving birth (p < 0.001). BAP levels in breastmilk in the early puerperium were higher compared with the maternal BAP levels, and there was a positive correlation between BAP levels in breast-milk and those in the maternal plasma (p < 0.05). Discussion: Regarding the oxidative stress and the antioxidant defense system of breast-feeding mothers, the d-ROMs level was highest and the BAP level was lowest in the early puerperium. The BAP level then showed a clear tendency to recover in the first 3 months after giving birth. Conclusion: When the maternal antioxidant potential remains at a low level after giving birth, careful consideration should be given to the mother’s health and wellbeing because there is a possibility that it might affect the antioxidant potential of breastmilk.
