- 3,774 women
Plasma glucose concentration 1 hour after a 50-g oral glucose challenge and complete information on pregnancy outcome was obtained.
- Average 1-hour plasma glucose concentration (mg/dl) was elevated in women who smoked at study enrolment compared with women who had never smoked.
- Women who smoked 10 or more cigarettes per day have a greater risk of gestational diabetes mellitus than women who smoked less.
- These findings support an association between smoking and gestational diabetes mellitus.
- Yes (with confidence)
- Gestational diabetes mellitus, or glucose intolerance first detected during pregnancy, affects 3–5 percent of pregnancies
