Maternal Gestational Diabetes and Trajectories of Offspring Fat–Lean Balance in the Millennium Cohort Study

Diabetes Obes MetabPublished Prospective cohort study

Authors' conclusion

Maternal GDM exposure was associated with age-varying differences in offspring fat mass and fat-lean balance during childhood and adolescence, and these associations were attenuated after adjustment for maternal pre-pregnancy adiposity.

Study context

Population
Offspring in the UK Millennium Cohort Study, body composition trajectories from ages 7–17 years
Participants
14,329 offspring
Exposure
Offspring exposed to maternal gestational diabetes mellitus (GDM) vs unexposed offspring
  • GDM-exposedn = 170
Outcome
Body composition trajectories: FM, BF%, FMI, FFMI and FMI/FFMI ratio
Follow-up
Ages 7-17 years
Methodological detailslinear mixed-effects models, adjusted for maternal pre-pregnancy adiposity
  • Linear mixed-effects models
  • Adjusted for maternal pre-pregnancy adiposity

Main finding

As reported in the abstract

Body composition indices (primary adjusted model)
GDM-by-age interaction: age-varying between-group differences for fat mass (FM), fat mass index (FMI) and FMI/fat-free mass index (FFMI) ratio
all p < 0.05
GDM-by-age interaction for BF%: borderline evidence
p = 0.050

Observational data: associations, not effects.

Further findings

Body composition after additional adjustment for maternal pre-pregnancy adiposity

Between-group differences attenuated; some age-specific contrasts, particularly at age 7 years, no longer statistically significant; age-varying patterns remained evident for several indices
