N/ACompletedNCT01968330

University of South Florida53 enrolled

Overview

This study will be a randomized controlled trial involving obese women obtaining prenatal care at an obstetric care clinic. Study subjects will undergo prenatal care in a group setting or prenatal care with a behavioral intervention to improve sleep. Anthropometric measurements, blood draws, questionnaires and at home sleep studies will be completed at three specified times (two antepartum and one postpartum). Primary outcome will be a comparison of postpartum weight loss amongst the intervention and control groups.

Outcomes

Primary Outcomes

Weight loss at 6 weeks postpartum.

The Primary objective of this study is to determine if a sleep intervention delivered in a group prenatal care setting of obese women can improve weight loss at one year postpartum (i.e. patient's ability to loose weight gained in pregnancy). This will be accomplished by: * Randomizing study subjects to groups with or without a sleep intervention component * Assessing weight, neck and abdominal circumference at each prenatal visit and at six weeks postpartum * Obtaining information regarding the patient's pre-pregnancy weight. * Assessing baseline sleep habits with at home polysomnography and actigraphy and repeating these measurements in the late third trimester as well as postpartum. * Assessing sleep habits through the Epworth Sleepiness scale and Pittsburgh Sleep Quality Index at baseline. * Obtaining qualitative feedback on the patient's experience with the sleep program and their sleep habits.

Time frame: six weeks postpartum

Secondary Outcomes

Affects of improved sleep on insulin resistance and cholesterol levels

The secondary objective will be to assess the affect of a sleep intervention on insulin resistance and cholesterol levels. This will be accomplished by: * Assessing glucose, insulin, HOMA, AUCgluc, leptin, adiponectin, total cholesterol, HDL, LDL, triglyceride levels at four time points in pregnancy and postpartum. * Completing the PRIME screen, a diet assessment tool, at approximately 20 weeks, 34 weeks and 6 and weeks postpartum * Assessing the neonates body composition at birth.

Time frame: From the second trimester of pregnancy to six weeks postpartum
