An eHealth Intervention in Pregnancy on Maternal Body Composition and Subsequent Perinatal Outcomes: A Randomized Trial
Authors' conclusion
Lifestyle interventions during pregnancy may attenuate gestational fat mass gain, particularly among women with normal weight and those who exceed GWG guidelines, with potential implications for neonatal health outcomes.
Study context
- Population
- Pregnant individuals enrolled in Louisiana's Women, Infants, and Children program
- Participants
- 351 individuals
- Comparison
- Multicomponent eHealth intervention in pregnancy vs usual care
- Interventionn = 179
- Usual Caren = 172reference
- Primary endpoint
- Body composition changes (fat percentage, fat mass, fat-free mass by bioelectrical impedance)
- Follow-up
- Early to late pregnancy
Methodological detailspragmatic
- Pragmatic
Primary result
As reported in the abstract
Fat mass, fat mass index and fat percentage gains
- No significant between-group differences in fat-free mass
- Intervention vs Usual Care: P < 0.05
Further findings
- Fat mass change interacted with intervention effects on neonatal health outcomes
- P = 0.01
