This study is designed to evaluate the amount of heart rate variability (HRV) for women with gestational diabetes mellitus (GDM) and to determine whether women with GDM have transient sleep-disordered breathing (SDB) during pregnancy.

Condition Intervention
Gestational Diabetes Mellitus
Other: Determining a change in heart rate variability post delivery of the baby

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: A Pilot Study to Evaluate the Association Between Gestational Diabetes, Heart Rate Variability and Sleep-Disordered Breathing

Further study details as provided by Christiana Care Health Services:

Primary Outcome Measures:
  • Improvement in heart rate control post-GDM [ Time Frame: Two months after delivery ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Study Start Date: November 2008
Estimated Study Completion Date: July 2016
Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
