OBJECTIVE
The aim of this study was to evaluate the associations of a lifetime history of hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM) with menopausal symptoms in midlife.
METHODS
This was a secondary analysis of women participating in Project Viva, an ongoing cohort enrolled during pregnancy. The exposure was lifetime history of HDP or GDM assessed for the index pregnancy by review of outpatient and hospital medical records and for all other pregnancies by interview or questionnaire at study entry (1999-2002) and the midlife visit (2017-2021). The primary outcome was the Menopause Rating Scale (MRS) applied at the midlife study visit. We used linear or logistic regression models adjusted for covariates such as baseline age, race/ethnicity, education, married/cohabiting, household income, baseline parity, age at menarche, and body mass index at midlife.
RESULTS
Of the 676 included participants, 120 (18%) had a history of HDP, and 47 (7%) had a history of GDM. The mean (SD) age was 52 (3.9) years at the midlife visit, and 48% of the participants had experienced menopause. There were no consistent differences in total, domain-specific, or individual symptoms in women with a history of HDP or GDM. A history of HDP and/or GDM was not associated with age at the onset of natural menopause.
CONCLUSIONS
Our findings do not support an association of a history of HDP or GDM with the severity of menopausal symptoms or age at the onset of natural menopause. Larger studies of women with a history of these pregnancy complications are needed to clarify their association with menopausal symptoms.
