Brief Summary:
This is a randomized, double-blind trial looking at how nutrition intake is associated with labor progress and complications.

Condition or disease Intervention/treatment Phase
Labor, Obstetric Dietary Supplement: Energy-containing soft drink Not Applicable

Detailed Description:
Insufficient intake of energy during labor may result in poor labor progress. The study investigates the effect of an energy supplement during labor.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Nutrition as Determinant of Labor Outcome
Study Start Date : September 2006
Actual Primary Completion Date : October 2008
Actual Study Completion Date : December 2009

Intervention Details:
  • Dietary Supplement: Energy-containing soft drink
    Commercial energy/sports drink

Primary Outcome Measures :
  1. The course of the labor by women (parity 0) at gestational age > 36 weeks, including: total labor time [ Time Frame: At time of birth ]

Secondary Outcome Measures :
  1. Length of stage 1 (cervical opening < 10 cm) and stage 2 (pushing time)
