    Gestational diabetes mellitus (GDM) affects maternal and neonatal health, with its global prevalence increasing significantly.

  • 2

    A prospective cohort study enrolled 1,030 pregnant women to investigate the impact of light exposure on GDM risk.

  • 3

    The study found that longer indoor light exposure and increased electronic device use are significant independent risk factors for GDM.

  • 4

    A dose-response relationship indicated that exceeding 3 hours of daily electronic device use and indoor light exposure significantly increased GDM risk.

  • 5

    Outdoor protective measures were identified as having a strong protective effect against the risk of developing GDM.
