Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Women presenting will be randomized to a lifestyle modification intervention or standard care control group before 16 gestational weeks. The intervention will focus on improving: (1) physical activity levels and (2) diet quality and calorie intake. The lifestyle intervention will be delivered within an empowerment theoretical framework through individualized intervention sessions, intensive group sessions, and by phone calls. The intervention will continue through the first postpartum year and will include the infants. A key objective is to evaluate whether the intervention optimizes infant BMI z-score. We will also evaluate whether the intervention increases the number of women who experience appropriate gestational weight gain, and evaluate several additional aims including relating the interventions with improved insulin sensitivity and beta-cell function in the women, and insulin concentrations adjusted for glucose in their infants.This study will also help us to identify and overcome barriers to develop effective ways of intervening during pregnancy to meaningfully improve cardio-metabolic risk trajectories of future generations.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Lifestyle and nutrition control group
The control arm will receive routine prenatal care in the prenatal clinic. They will receive regular phone calls and mailings, token gifts and some useful information from data collected in the study, such as physical activity, feedback on behavior throughout the study. To additionally promote adherence (since they will have less contact with study staff), we will include 2 pre-partum and 1 post-partum group sessions meant to increase bonding between participants and retention of control participants. These sessions will include general pregnancy information not related to our interventions.
No interventions assigned to this group
Lifestyle intervention group
The lifestyle intervention will be delivered within an empowerment framework which promotes behavioral changes by facilitating health self-efficacy, utilizing self-praise and using active coping skills to address and manage emotions. A nutrition component primarily focuses on total calories, for which energy requirements will be individually calculated for each pregnant women and on general diet quality with an emphasis on carbohydrate quality. It will also promote an overall healthy diet, emphasizing improvement of fat quality and reducing salt intake. A physical activity component focuses on promoting regular movement and minimizes the duration of bouts of sitting or lying during waking hours as well as non-exercise activity.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Gestational age at randomization no earlier than 9 weeks 0 days and no later than 15 weeks 6 days based on an algorithm that compares the last menstrual period (LMP) date and data from the earliest ultrasound.\*
* BMI ≥25 kg/m2 based on first trimester measured weight and on measured height. The earliest weight measurement before randomization, measured specifically for the study will be used. Reported pre-pregnancy weight will not be used to determine eligibility because of the potential for inaccuracy. If the earliest weight measurement is conducted at 140 to 146 weeks or 150 to 156 weeks, 1 lb or 2 lbs will be subtracted from the measured weight respectively, to adjust to a first trimester weight.\*
* Age ≥ 18\*
Exclusion Criteria
* Known fetal anomaly \*
* Planned termination of pregnancy\*
* History of three or more consecutive first trimester miscarriages\*
* Past history of anorexia or bulimia by medical history or patient report. Binge eating disorder is not an exclusion\*
* Current eating disorder diagnosed by EDE-Q questions 2-4 and confirmed after discussion with the participant by study staff\*
* Actively suicidal defined as a value ≥ 2 on the BDI-II question 9\*
* Prior or planned (within 1 year of expected delivery) bariatric surgery\*
* Current use of one or more of the following medications: \*
* Metformin
* Systemic steroids
* Antipsychotic agents
* Anti-seizure medications or mood stabilizers that would be expected to have a significant impact on body weight
* Medications for ADHD including amphetamines and methylphenidate
* Continued use of weight loss medication including OTC and dietary supplements for weight loss \*
* Contraindications to aerobic exercise in pregnancy specified in the ACOG Committee Opinion #267, 2002 (reaffirmed 2009) \*
* Hemodynamically significant heart disease defined as an AHA class II (short of breath with exercise) or greater
* Restrictive lung disease (e.g. pulmonary fibrosis)
* Poorly controlled seizure disorder
* Poorly controlled hypertension (blood pressure ≥160/110)
* History of extreme sedentary lifestyle (e.g. bed bound)
* Orthopedic limitations to aerobic exercise
* Severe anemia defined as a hemoglobin \< 8 g/dl or hematocrit \<24 %
* Participation in another interventional study that influences weight control\*
* Enrollment in this trial in a previous pregnancy\*
* Intention of the participant or of the care provider for the delivery to be outside the LIFE-Moms Consortium hospital\*
* Participant's unwillingness or inability to commit to a 1 year follow-up of herself or her child, including planning to move away\*
* Past or current intravenous drug use (visual check for injection marks, recorded methadone use, self-report)
* Self-reported HIV infection (confirmed from medical records or baseline test results)
* Inability to functionally participate in group sessions and other study requirements on a regular basis during the complete duration of the study, including but not limited to the documented use of the accelerometer for the periods required by the study
* Non Spanish speaking
* Plan on giving up infant for adoption
