Energy Intake
Prazo: 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
Prazo: 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
Prazo: 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.
|
Approximately 7 days within 35-37 weeks gestation

|
Energy Expenditure During Sleep
Prazo: 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).
