Hypothesis
Is there an association between cigarette smoking during pregnancy and the risk of developing gestational diabetes mellitus?
Conclusion
Current data do not support an association between cigarette smoking during pregnancy and the risk of gestational diabetes.
Supporting Evidence
- The review included 32 studies, but only 12 met the criteria for inclusion.
- Most studies provided only unadjusted measurements.
- The overall odds ratio for the association was 1.03, indicating no significant risk.
- Only four studies provided adjusted measurements, with an odds ratio of 0.95.
Takeaway
The study looked at whether smoking while pregnant causes diabetes in pregnant women, and it found that it doesn't seem to be a problem.
Methodology

Potential Biases
Potential information bias due to self-reported smoking habits.
Limitations
The number of studies is small, and there is significant heterogeneity in research design and findings.
Participant Demographics
Studies included various populations, but specific demographics were not detailed.
