How many pregnant women were in the Lp(a) gestational diabetes risk study?
The question asks about the number of pregnant women with normal glucose tolerance (NGT) in a study on lipoprotein(a) (Lp(a)) and gestational diabetes risk. The study, a retrospective cohort, matched 922 women with GDM to 922 women with NGT, so there were 922 women in the NGT group.
What the research says
The study was a retrospective cohort of 14,527 pregnant women, from which 922 women with GDM were matched to 922 women with normal glucose tolerance (NGT) using propensity score matching 7. The NGT group served as the control for comparing Lp(a) levels and GDM risk 7. Other studies on GDM have included varying numbers of NGT women; for example, a systematic review included 285,351 women with NGT 10, and a smaller study had 44 NGT women 9.
What to ask your doctor
- What does my Lp(a) level mean for my risk of gestational diabetes?
- Should I have my Lp(a) checked early in pregnancy?
- How does Lp(a) compare to other risk factors for GDM?
- Are there any lifestyle changes that can lower Lp(a) or GDM risk?
