A study of more than 4,700 postmenopausal women found that menopause before age 40 was associated with higher cardiovascular disease and coronary heart disease risks, along with insulin levels 9.3% higher. The findings do not establish that higher insulin causes the increased risk, and researchers found no corresponding increase for stroke or heart failure.
A study of more than 4,700 postmenopausal women found that menopause before age 40 was associated with higher risks of cardiovascular disease and coronary heart disease, as well as insulin levels 9.3% higher than those observed after menopause at age 45 or later. The findings, which researchers will present at The Menopause Society’s 2026 annual meeting, point to insulin resistance as a possible link, but do not prove it causes the higher heart risk.
The researchers followed participants for a mean of 21.4 years and recorded 1,570 cardiovascular events. They compared women who experienced premature menopause, defined as menopause before age 40, with those whose menopause occurred at age 45 or later. Premature menopause was associated with greater risks of cardiovascular disease and incident coronary heart disease, according to the study summary.
The association was not found for every outcome studied: premature menopause was not associated with higher stroke or heart failure risk. Nor did the researchers find a higher risk of the listed heart outcomes among women with early menopause, which the report defines as menopause between ages 40 and 44. The premature-menopause group had higher insulin levels, but fasting glucose levels did not differ.
The work is titled “Premature menopause and cardiovascular disease risk in the Aric Study: mediation by insulin resistance.” The source report says the findings will be presented at The Menopause Society meeting in San Diego, scheduled for October 20-24, 2026. The supplied report does not provide a journal publication or full study tables.
Why Insulin May Matter
The findings suggest one possible biological pathway behind a known association between menopause before age 40 and cardiovascular disease. Higher insulin alongside unchanged fasting glucose may be relevant because researchers focused on insulin resistance as a cardiometabolic factor that could help explain the relationship. But the study summary describes a possible pathway, not proof that insulin resistance accounts for the increased heart risk.
For readers, the results add detail to a health issue that can affect people well before the usual age of menopause. The study does not establish an individual’s personal risk or show that a particular test or intervention prevents heart disease. It may inform future research into how cardiovascular risk is assessed for women with premature menopause; medical decisions should be discussed with a qualified health professional.

Menopause Timing in the Study
The report defines premature menopause as menopause before age 40 and early menopause as occurring from 40 through 44. It says about 1% of women experience premature menopause. Women in this group spend more years in postmenopause, and previous research has linked premature menopause with several adverse health outcomes, including cardiovascular disease and osteoporosis.
This study examined more than 4,700 postmenopausal women aged 45 to 64 when included, according to the source report. Its focus was whether cardiometabolic factors, particularly insulin resistance, might help explain the association between premature menopause and cardiovascular disease. The results are being presented at a scientific meeting; the supplied material does not report a peer-reviewed paper or provide enough methodological detail to assess the full analysis.
“Our findings suggest that insulin resistance may be one important pathway linking premature menopause with increased cardiovascular disease risk, highlighting the importance of cardiometabolic health in women who experience menopause before age 40.”
— Dr. Zailing Xing, first author of the study
What the Findings Cannot Show
The reported results show associations, not cause and effect. The summary does not say that higher insulin caused cardiovascular events, or that insulin resistance fully explains the relationship with menopause timing. It also does not give the absolute event rates for each menopause group, the size of the risk increases, or detailed information on adjustments for other risk factors.
The source material does not include the study’s full methods, confidence intervals, or a peer-reviewed publication, so those details cannot be assessed here. It is also unclear from the report whether the analysis found that insulin resistance statistically mediated the association, despite the presentation title. The findings do not show that women with premature menopause will necessarily develop heart disease or that a specific screening or treatment approach reduces risk.
Meeting Presentation and Further Evidence
Researchers are scheduled to present the results at The Menopause Society’s annual meeting in San Diego, October 20-24, 2026. The presentation may provide fuller information about the analysis, including how the researchers measured insulin resistance and calculated cardiovascular risks. The supplied report does not state whether a journal publication is planned or when additional results may become available.
Further published research would help clarify whether insulin resistance explains part of the observed relationship and how the findings compare with other studies. Until more evidence is available, the reported results are best understood as a possible clue to cardiovascular risk, not a clinical recommendation. Anyone concerned about menopause timing or heart health should seek guidance from a qualified health professional.
Key Questions
What did the study find about premature menopause?
Among more than 4,700 postmenopausal women, menopause before age 40 was associated with higher risks of cardiovascular disease and coronary heart disease compared with menopause at age 45 or later. The report does not provide the size of those risk increases.
How were insulin levels different?
The premature-menopause group had insulin levels reported as 9.3% higher. Fasting glucose levels did not differ, according to the study summary.
Did the study link premature menopause to stroke or heart failure?
No higher risk of stroke or heart failure was reported for the premature-menopause group. The summary also says early menopause, between ages 40 and 44, was not associated with higher risks of the heart outcomes studied.
Does higher insulin prove the cause of the heart risk?
No. The researchers describe insulin resistance as a possible pathway. The reported association does not establish that higher insulin causes cardiovascular disease or accounts for the full relationship.
When will the results be presented?
The study is scheduled for presentation at The Menopause Society’s annual meeting in San Diego, October 20-24, 2026. The source report does not give a date for a journal publication.
