Age at Menarche, Menstrual Characteristics, and Risk of Preeclampsia

الملخص EN

We examined associations of age at menarche and menstrual characteristics with the risk of preeclampsia among participants (n=3,365) of a pregnancy cohort study.

Data were collected using in-person interviews and medical record abstraction.

Logistic regression was used to estimate adjusted odds ratio (OR) and 95% confidence interval (95% CI).

There was a significant inverse association between age at menarche and risk of preeclampsia (P value for trend < 0.05).

Association of long cycle length (>36 days) with higher risk of preeclampsia was present only among women who had prepregnancy body mass index <25 kg/m2 (interaction P value = 0.04).

Early menarche is associated with higher risk of preeclampsia.

Prepregnancy weight may modify associations of long menstrual cycles with risk of preeclampsia.
