Key result
Plasma beta-endorphin levels increased significantly during labor and correlated strongly with uterine muscle contraction (r = 0.966, P<0.05) and cervical effacement (r = 0.974, P<0.05).
Why the study?
Do plasma beta-endorphin levels correlate with uterine muscle contractions and cervical effacement during labor?
Population
Pregnant women in the third trimester, during labor, and 72 hours after delivery, and non-pregnant controls.
Design
Cohort
Follow-up
Up to 72 hours after delivery

Should not change labor practice; leaves open causal role and need for prospective validation.
Observational
Do plasma beta-endorphin levels correlate with uterine muscle contractions and cervical effacement during labor?
Effect estimate: r = 0.966
p-value: p=<0.05
Plasma beta-endorphin levels increase significantly during labor and strongly correlate with uterine muscle contraction and cervical effacement.
Weissberg et al. (1990) conducted an observational in Pregnancy and labor. Beta-endorphin levels vs. Non-pregnant controls was evaluated on Correlation of beta-endorphin levels with uterine muscle contraction (r = 0.966, p=<0.05). Plasma beta-endorphin levels increased significantly during labor and correlated strongly with uterine muscle contraction (r = 0.966, P<0.05) and cervical effacement (r = 0.974, P<0.05).
