Hypothesis
This study aims to assess leptin concentrations in breast milk during the first 180 days postpartum and determine their relationship with circulating hormone levels in lactating women.
Conclusion
Leptin concentrations in breast milk decrease with time during lactation and show significant relationships with other maternal hormones.
Supporting Evidence
- Leptin concentrations in breast milk were highest in colostrum and decreased significantly over the first 180 days.
- Colostrum leptin concentrations correlated with maternal serum leptin, cortisol, and thyroxine levels.
- Mature milk leptin concentrations correlated with maternal serum leptin and insulin levels.
Takeaway
Breast milk has a hormone called leptin that helps babies grow, and the amount of this hormone changes as the baby gets older.
Methodology
Blood and breast milk samples were collected from 160 breastfeeding women at different stages postpartum, and leptin levels were measured using various assays.
Limitations
The longitudinal study was limited to the first 30 days of lactation due to recruitment challenges.
Participant Demographics
Participants were healthy lactating women with an average age of 30 years and a BMI around 26.
