Main findingResult — go to the resultOdds ratio 12Authors' conclusion
Results highlight potentiating effects of cannabis exposure in the context of maternal tobacco use in pregnancy on obesity risk and the importance of multi-method assessments of obesity.
Study context
- Population
- Diverse sample of pregnant women and their children followed from birth to mid-childhood (9–12 years)128 with adiposity outcomes
- Participants
- 262 participants
- Exposure
- Prenatal tobacco-only or tobacco + cannabis co-exposure vs no exposure
- Outcome
- Child BMI (kg/m²) trajectories, overweight/obese status by BMI percentiles, and adiposity (fat mass [kg], fat mass [%], fat free mass [kg])
- Follow-up
- Birth to mid-childhood (9-12 years)
Methodological detailsoversampled for prenatal substance use
- Oversampled for prenatal substance use
Main finding
As reported in the abstract
birth to mid-childhood
Odds ratio
12
Observational data: associations, not effects.
Further findings
Adiposity (fat mass, fat mass %) · mid-childhood
- Co-exposure: significantly greater fat mass and fat mass % vs no exposure
- Tobacco-only: no different from no exposure
