In a retrospective cohort of 954 pregnant individuals with type 2 diabetes, weight gain <5 kg is linked to lower risk of large-for-gestational-age birth weight (aOR 0.42, 95% CI 0.29–0.59).
- Why it matters: Pregnancies complicated by type 2 diabetes face elevated adverse perinatal outcomes, and it is unclear whether restricted weight gain changes risk for key complications.
- What they did: The study compared perinatal outcomes between 327 pregnancies with weight gain <5 kg and the remainder with ≥5 kg, using logistic regression adjusted for covariates.
- The result: Weight gain <5 kg was also associated with reduced neonatal intensive care unit admission (aOR 0.74, 95% CI 0.55–0.98), hypertensive disorders of pregnancy (aOR 0.56, 95% CI 0.42–0.75), and cesarean delivery (aOR 0.66, 95% CI 0.48–0.91), without significant increases in small-for-gestational-age birth weight or preterm birth.
