DESCRIPTION (provided by applicant): A randomized controlled trial is proposed to study the effect, in a cohort of racially and ethnically diverse group of overweight and obese pregnant women, of an Intensive Lifestyle Intervention (ILI) compared to Usual Care (UC) on gestational weight gain (GWG), infant fatness, and mothers' post-delivery weight retention. Women in the ILI arm will receive intensive counseling during pregnancy and group counseling after delivery regarding behavior, nutrition, and physical activity change. Visits to counselors will be weekly and additional telephone and internet contacts will occur. The mothers' will be assessed at 14 and 36 weeks of pregnancy and at 12 weeks and 52 weeks post-delivery. The measurements will be anthropometry, whole body MRI, EchoMRI, and whole body plethysmography (BodPod). The infants' measurements will be anthropometry, whole body MRI, EchoMRI, and whole body plethysmography (PeaPod) for fatness 12 weeks and 52 weeks. Mothers and children will have cardio-metabolic risk factors measured in plasma. Data will be collected regarding mothers' dietary intake and physical activity (questionnaires and accelerometry) to assist in counseling. Other data to be collected include questionnaires on quality of life, socio-economic status. Careful record will be kept of expenses in providing the ILI, so that cost analysis of the intervention can be calculated. The study is powered on the primary outcome, fatness of the infants at birth. We require 180 participants to attain appropriate power. We will enroll 210 so as to allow for some dropouts along the way. Each mother will be followed during pregnancy and for a year post delivery. Each infant will be followed for a year after birth. We have the ability o continue to follow these participants if further funding is forthcoming, as they are all local to or hospital's catchment area and our own physicians. If aims are achieved, namely that both children and mothers profit from the intervention, there should be a paradigm shift in how overweight pregnant women are treated. At present, there is a dearth of behavioral advice and intervention relating to GWG and physical activity provided to these women. Positive results from our study would provide evidence for ILI preventative intervention.

描述（由申请人提供）：拟进行一项随机对照试验，在一组不同种族和民族的超重和肥胖孕妇中，研究强化生活方式干预（ILI）与孕期护理（UC）对妊娠期体重增加（GWG）、婴儿肥胖和母亲产后体重保持的影响。ILI组的妇女将在怀孕期间接受强化咨询，并在分娩后接受有关行为、营养和体力活动变化的团体咨询。对辅导员的访问将每周进行一次，并将进行额外的电话和互联网联系。母亲们将在怀孕14周和36周以及产后12周和52周时接受评估。测量将包括人体测量、全身MRI、EchoMRI和全身体积描记术（BodPod）。婴儿的测量将是人体测量，全身MRI，EchoMRI和全身体积描记术（PeaPod），用于12周和52周的肥胖。母亲和儿童将在血浆中测量心脏代谢危险因素。将收集关于母亲饮食摄入和身体活动的数据（问卷和加速度计），以协助咨询。收集的其他数据包括关于生活质量、社会经济状况的问卷。将仔细记录提供ILI的费用，以便计算干预措施的成本分析。这项研究的主要结果是婴儿出生时的肥胖。我们需要180名参与者才能获得适当的权力。我们将招收210人， 让一些人沿着辍学。每位母亲将在怀孕期间和分娩后一年内接受随访。每个婴儿出生后将被跟踪一年。如果进一步的资金即将到位，我们有能力继续跟踪这些参与者，因为他们都是当地或医院的集水区和我们自己的医生。如果实现了目标，即儿童和母亲都从干预措施中受益，那么超重孕妇的治疗方式应该发生范式转变。目前，向这些妇女提供的与生殖器工作和体育活动有关的行为咨询和干预非常缺乏。 本研究的阳性结果将为ILI的预防性干预提供依据。
