(Press-News.org) PITTSBURGH, July 9, 2025 — During the menopause transition, only 1 in 5 women have optimal scores using the American Heart Association’s health-assessment tool, known as Life’s Essential 8 (LE8). Among the tool’s eight components, four of them — blood glucose, blood pressure, sleep quality and nicotine use — are key in driving future cardiovascular risks, with sleep being particularly crucial for long-term cardiovascular health.
The findings – published today in Menopause – were made by researchers at the University of Pittsburgh, Albert Einstein College of Medicine and Baylor University.
“Previously we’ve shown that the menopause transition is a time of accelerating cardiovascular risk,” said senior author Samar R. El Khoudary, Ph.D., M.P.H., professor of epidemiology at Pitt’s School of Public Health. “This study underscores that it’s also an opportunity for women to take the reins on their heart health.”
The team analyzed health data collected from about 3,000 women who participated in the Study of Women’s Health Across the Nation (SWAN), an ongoing, longitudinal, multi-site, multi-ethnic study of midlife women that began in 1996. The researchers compared the women’s LE8 scores at baseline, around age 46, to their evolving health trajectories over time, from subclinical cardiovascular disease measures, such as increased carotid-artery thickness, to cardiovascular events, including heart attacks and strokes, to mortality of all causes. The team also examined impacts of each of the individual LE8 components: nutrition, physical activity, smoking abstinence, sleep, body mass index, blood lipids, blood sugar and blood pressure.
The analysis showed that four LE8 components — blood glucose, blood pressure, sleep quality and nicotine use — were the most important factors driving the study participants’ future cardiovascular risks.
Above all, sleep emerged as a potential predictor for long-term effects of cardiovascular disease events and all-cause mortality, though it was not linked to the shorter-term effects of carotid-artery thickening. The team found that at midlife, meeting the bar for healthy sleep, defined in Life’s Essential 8 as seven to nine hours on average for most adults, may contribute to women’s heart health and longevity, a hypothesis that should be tested in a future clinical trial, said Ziyuan Wang, Ph.D. candidate at Pitt Public Health and first author.
Low total LE8 scores correlated with increased cardiovascular risk, as expected—however, only 21% of the midlife women studied had an ideal LE8 score.
“With heart disease being the leading cause of death in women, these findings point to the need for lifestyle and medical interventions to improve heart health during and after menopause among midlife women,” said El Khoudary.
Other authors on the study were Ziyuan Wang, M.S., Emma Barinas-Mitchell, Ph.D., Maria M. Brooks, Ph.D., Jared W. Magnani, M.D., M.Sc., and Rebecca C. Thurston, Ph.D., all of Pitt; Carol A. Derby, Ph.D., of Albert Einstein College of Medicine; and Kelly R. Ylitalo, Ph.D., of Baylor University.

Why do some brain regions resist Alzheimer’s?
2025-07-09
It’s been recognized for some time that Alzheimer’s disease affects brain regions differently and that tau — a protein known to misbehave — plays an important role in the disease. Normally, tau helps stabilize neurons, but in Alzheimer’s disease, it begins to misfold and tangle inside neurons. It spreads across the brain forming toxic clumps that impair neuronal function and ultimately lead to cell death.
Brain areas like the entorhinal cortex and hippocampus succumb early to tau tangles, while other areas, like the primary sensory cortices, remain resilient to the disease. In the quest to better understand this selective ...
Like humans, monkeys are attracted to videos showing conflict
2025-07-09
COLUMBUS, Ohio – Have you ever wondered what kind of video content would most grab the attention of monkeys?
A new study of long-tailed macaques suggests the monkeys seem to like some of the same kind of content that humans do: videos featuring aggression and individuals they know.
“Humans and macaques are both social animals who have a fundamental need to belong,” said Brad Bushman, co-author of the study and professor of communication at The Ohio State University.
“It’s not surprising that they both would be most interested in the video content that may help ...

Addressing “spay-neuter syndrome" with testosterone restoration for neutered male dogs
2025-07-09
The Parsemus Foundation, a nonprofit dedicated to advancing pet health, today announced the publication of groundbreaking research on the safety and dosing of testosterone therapy for neutered male dogs. Published in BMC Veterinary Research, this pivotal study provides crucial data for veterinarians to treat "spay-neuter syndrome” - a collection of health and behavioral problems associated with hormone loss following sterilization. Results show that injectable testosterone can safely restore physiological hormone levels in neutered dogs, offering ...

More rural, minoritized people get amputations – AI gets closer to why
2025-07-09
Why do rural adults and racial and ethnic minorities with vascular disease get major leg amputations more often? A new study out today in Epidemiology uses AI to solve the mystery, finding an unaccounted-for factor that researchers think points to implicit bias in the clinical decision-making process.
“The AI model allowed us to distinguish among the many reasons behind these much higher rates of amputation among certain groups of people with vascular disease,” said Paula Strassle, ...
First look at defects in single-crystal indium gallium zinc oxide could fix persistent display instability
2025-07-09
Many displays found in smartphones and televisions rely on thin-film transistors (TFTs) made from indium gallium zinc oxide (IGZO) to control pixels. IGZO offers high transparency due to its large bandgap (the gap existing between the valence and conduction bands), high conductivity, and can operate even in an amorphous (non-crystalline) form, making it ideal for displays, flexible electronics, and solar cells. However, IGZO-based devices face long-term stability issues, such as negative bias illumination stress, ...
Understanding childhood maltreatment and its effect on biological aging
2025-07-09
Childhood maltreatment leaves a lasting impact that goes far beyond physical injuries or fading memories. Scientific evidence has long shown that children who experience abuse and neglect face increased risk of chronic diseases, mental health disorders, and premature death throughout their lives. Beneath these visible signs lies a deeper truth: childhood maltreatment can fundamentally alter a child’s biology, triggering molecular changes that can last for decades.
Recent research is unravelling that childhood maltreatment doesn’t ...
Turning step-growth into chain-growth with click polymerization
2025-07-09
A controlled/“living” click polymerization method developed by researchers at Institute of Science Tokyo and Nagoya University enables precise chain-growth of AB-type monomers—traditionally limited to step-growth processes—by leveraging copper-catalyzed azide–alkyne cycloaddition. The approach achieves well-defined polymers with narrow dispersity and enables the bidirectional synthesis of ABA-type block copolymers, offering a powerful new strategy for constructing functional macromolecular architectures from a wide range of monomers.
Traditional polyaddition reactions involving AB-type monomers, which contain both azide and alkyne ...
Researchers find surgical technique reduced risk of early preterm birth for patients with cervical insufficiency
2025-07-09
A new study by investigators from Mass General Brigham adds evidence that the most effective way to prevent preterm birth among patients with a history of cervical insufficiency is to place a cervical stitch higher in the abdomen rather than vaginally. This difference in surgical technique was associated with a 70% reduction in risk of preterm birth (birth before 34 weeks) among patients at Brigham and Women’s Hospital (BWH), a founding member of the Mass General Brigham healthcare system, where approximately 6,200 babies are born every year. ...
