Ultra-processed Foods and Diet Quality in Association With Long-term Weight Change and Progression to Type 2 Diabetes Among Individuals With a History of Gestational Diabetes Mellitus—A Prospective Study

Diabetes CarePublished Prospective cohort study

Authors' conclusion

In women with a history of GDM, UPF consumption was associated with weight gain and higher T2D risk, even among those with higher diet quality.

Study context

Population
Women with a history of gestational diabetes mellitus (GDM), Nurses' Health Study II (1991–2021)
Participants
4,207 women
Exposure

Outcome
Long-term weight change and progression to T2D
Methodological detailstime-updated cumulative averages, generalized estimating equations, Cox regression
  • Time-updated cumulative averages

Observational data: associations, not effects.

Further findings

Weight change with increased UPF consumption (quartiles of change) · greater weight gain with increased UPF

P for trend < 0.0001

  • Weight change with increased UPF consumption (quartiles of change): Generalized estimating equations (GEE) analysis, n = 3,781

Associations in women with higher AHEI scores

Associations persisted in women with higher AHEI scores

Joint UPF and AHEI modelling · 4 years

Only women with stable or decreased UPF intake and increased AHEI achieved 4-year weight maintenance
