Beskrivelse
Inclusion Criteria:
- Pregnant female
- BMI between 18.5 kg/m2 and 30.0 kg/m2 prior to the current pregnancy (determined by self report and confirmation of pregravid BMI of the index pregnancy from the prenatal record)
- Medically cleared for participation in the study by primary care obstetrician or midwife
- Medically cleared for participation by the Medical Investigator
- Medical record release (prenatal record, hospital delivery record) for study staff to access information in the medical record related to the current and if applicable, the prior pregnancy.
Exclusion Criteria:
- Risk of early delivery (eg. history of preterm birth, spontaneous abortion, evidence of gestational hypertension (SBP >160 mmHg & DBP >110 mmHg) or pre-eclampsia in the current pregnancy)
- History of intrauterine growth-restriction
- Persistent second- or third-trimester bleeding
- Placenta previa after 26 weeks gestation
- Incompetent cervix or cerclage
- Severe anemia
- High-order pregnancy (e.g. triplets)
- Family history of diabetes
- Heart or lung disease
- HIV or AIDS (self-reported)
- Individuals with contraindication to magnetic resonance spectroscopy such as having magnetic metallic objects in their body
- Unwillingness for placental biospecimens to be collected at delivery

Kohorter og interventioner
Gruppe / kohorteGruppe / kohorte |
Intervention / BehandlingIntervention / Behandling |
|---|---|
|
Active
Physically active will be defined by self-report and confirmed by step counts >8,000 per day from activity monitoring.
|
No behavioral intervention included but the exposure is level of physical activity.
Individuals in the Active group will be categorized by their own routine physical activity levels.
|
|
Sedentary
Sedentary lifestyle will be defined by self-report and confirmed by step counts <5,000 per day from activity monitoring.

No behavioral intervention included but the exposure is level of physical activity.
Individuals in the Sedentary group will be categorized by their own routine physical activity levels.

Relationship between in vivo mitochondrial capacity and infant in vitro mitochondrial capacity (by oxygen consumption rates)
Tidsramme: About 20 weeks

Relationship between in vivo mitochondrial capacity and maternal in vitro mitochondrial capacity (by oxygen consumption rate)
Tidsramme: About 15 weeks
|
Relationship between in vivo and in vitro mitochondrial capacity will be measured with in vivo mitochondrial capacity measured by 31P-MRS and maternal in vitro mitochondrial capacity measured by oxygen consumption rates in maternal primary myotubes
