Determinants of Gestational Weight Gain in Obese Pregnant Women (MomEE)
23. august 2021 oppdatert av: Leanne Redman, Pennington Biomedical Research Center
MomEE: Determinants of Gestational Weight Gain in Obese Pregnant Women
The purpose of this study is to measure energy intake and energy expenditure during and after pregnancy.
The investigators hypothesize that obese pregnant women with weight gain above the Institute of Medicine (IOM) guidelines, 'High Gainers', will have increased energy intake but no evidence for changes in energy expenditure after adjustment for the weight gained when compared to women with appropriate gestational weight gain, 'Normal Gainers'.
Additionally, the investigators will measure the babies born to the pregnant women enrolled in MomEE at one time point before 10 days of life.

|
Energy Intake
Tidsramme: Approximately 6 months (from 13-16 weeks gestation to 35-37 weeks gestation)
|
Energy intake is determined using the energy intake-balance method.
Energy intake was calculated as the sum of energy expenditure by doubly labeled water and energy deposition of fat and fat-free tissues by 3 compartment model using plethysmography and isotope dilution.
|
Approximately 6 months (from 13-16 weeks gestation to 35-37 weeks gestation)

Physical Activity
Tidsramme: Approximately 7 days within 13-16 weeks gestation
|
Physical activity is determined using daily mean amplitude deviation in milligrams by wrist worn accelerometer over a period of approximately 7 days within early pregnancy (13-16 weeks gestation).
Mean amplitude deviation describes the mean distance of data points from the mean, and higher values denote higher levels of physical activity.

Physical Activity
Tidsramme: Approximately 7 days within 35-37 weeks gestation
|
Physical activity is determined using daily mean amplitude deviation in milligrams by wrist worn accelerometer over a period of approximately 7 days within late pregnancy (35-37 weeks gestation).
Mean amplitude deviation describes the mean distance of data points from the mean, and higher values denote higher levels of physical activity.

Energy Expenditure During Sleep
Tidsramme: 1 day within 13-16 weeks gestation
|
Energy expenditure during sleep is determined by 1 overnight stay in a whole body calorimeter within early pregnancy (13-16 weeks gestation).
