Objective:

To investigate the associations of sleep variability and irregularity with the odds of gestational metabolic syndrome (GMS) and its components during pregnancy, highlighting the significance of these relationships.

Key Findings:
  • Greater sleep variability is associated with increased odds of GMS (aOR 1.348; 95% CI: 1.136-1.559) and dyslipidemia (aOR 1.086; 95% CI: 1.019-1.159).
  • No significant associations were found for hyperglycemia or hypertension.
  • Sleep irregularity showed no significant association with GMS or its components.
  • Increased vulnerability to GMS was noted in older women and those with a history of multiple pregnancies.
Interpretation:

Higher sleep variability during pregnancy is linked to a greater risk of developing GMS and dyslipidemia, with certain demographic factors influencing this risk, particularly maternal age and pregnancy history.

Limitations:
  • The study may not account for all confounding factors affecting sleep and metabolic health, such as [insert specific factors].
  • The findings are based on a specific population and may not be generalizable.
Conclusion:

The study highlights the importance of monitoring sleep variability in pregnant women as a potential modifiable risk factor for GMS and its components, suggesting avenues for future research and clinical practice.
